Abstract

Within social networks, relationships are “enacted.” They grow or decline through

communication and the exchange of social resources. Although geographic

distance can inhibit enactment, telecommunication technologies (e.g., phone, e-

mail, IM) are increasingly being used to maintain relationships over long

distances. In this paper, we examine the role these technologies play in

maintaining friendships. Taking advantage of a natural situation in which

friendships are at risk of ending, we follow students in their transition from high

school to college. When students move away from home, they reduce both their

communication with their old high school friends and their sense of psychological

connection to them. Longitudinal analyses show that communication slows the

decline in psychological closeness, but psychological closeness does not slow the

decline in communication. E-mail and IM are telecommunication technologies

that are especially useful among these students for maintaining friendships. The

usefulness of these technologies may stem from arbitrary pricing decisions, which

allow students to use them frequently, rather than from their intrinsic features,

such as media richness. Unlike the phone, pricing of e-mail and IM does not

depend on either message length or the distance the message must travel.

Introduction

People maintain only a limited number of personal relationships. Researchers

estimate that people typically keep ten to twenty important relationships, out of

the approximately 1,000 individuals whom they interact with or can identify (e.g.,

Fisher, 1982; Wellman, 1992). Friendships, in contrast to family relationships, are

especially fragile, and require active maintenance or they die (Canary & Stafford,

1994). While family ties exist because of the accident of birth and are often

maintained through obligation, friendship and romantic relationships are

voluntary. They grow, decline, and end through concrete actions (Allan, 1979).

In this paper we examine how young adults maintain friendships when faced with

life events that threaten them, such as moving from high school to college. In

particular, we examine the role that phone and computer communications play in

maintaining these friendships as the parties move geographically apart.

In Duck’s analogy (1988), friendships need a regular investment of effort;

otherwise, normal centripetal forces cause the friendship to come apart. In this

view, people develop and maintain particular relationships by enacting them, i.e.,

by carrying them out through regular exchanges of communication or social

support (Duck, 1988). Initial factors that bring people together, such as common

interests, shared work goals, beauty, or charm, lose power with time (Berg &

Clark, 1986). These factors must be supplemented with behavioral exchanges that

affect whether the relationship will be valued and retained, or devalued and

dropped (Berg & Clark, 1986). Regular contact is at the heart of friendship (Allan,

1979). We typically grow to like others with whom we communicate and spend

time, and this liking drives further companionship (Newcomb, 1961). It is in this

sense that friendships are enacted. They are maintained through communication

and other behavioral exchanges.

Since at least the 1930s, we have known that physical proximity increases the

likelihood of friendships and romantic relationships (e.g., Bossard, 1932;

Festinger, Schachter, & Back, 1950). However, when people are separated by

geographic distance, it becomes more difficult to enact relationships through

communication and the exchange of social support. As a result, when people

change residences and move away, personal ties often fade and dissolve. Rose

(1984), for example, found geographic separation to be the factor most often

associated with the disintegration of friendships.

Physical proximity is conducive to the growth and maintenance of personal

relationships, whereas physical distance leads to their dissolution. In part, this is

because proximity decreases the behavioral costs of communication between

people and hence increases its frequency, while distance increases the costs and

decreases the frequency. Proximity not only increases the frequency of

communication, but also shifts the types of interactions between individuals. For

instance, even if distant friends communicate frequently by phone and e-mail, the

distance itself make it difficult for them to spend leisure time together, to share

common activities, to be physically intimate, or to exchange certain types of

social support.

When people move apart, two factors contribute to the decline of the original

relationships. First, it becomes difficult to communicate with the people in the

original location. Second, building relationships in the new location consumes

some of the time and attention the person would need to maintain the old

relationships. As a result, friendships change after a move: one may drop a friend

altogether or shift that person from the active list to the list of those whom one

sends holiday greetings.

Communication technology and social relationships

Telecommunications technologies—literally communications at a distance—can

change the amount and type of communication between people who are located

remotely from each other, and thus can allow them to maintain friendships at a

distance. If friendships are enacted and maintained through communication, as

Duck proposed, then friendships among those who live far from each other are

less likely to decline the more they communicate. This hypothesis—that

communication regardless of the modality leads to the maintenance of friendships

at a distance— is over simplistic, and needs elaboration. In the section below we

discuss the evidence for how telecommunications affects friendship and features

of the relationships and the technology that moderate the link between

communication and friendship.

Differences among communication modalities. Phone, e-mail, and IM are the

three main telecommunication technologies used by American consumers. In

1876 the phone was invented, and in 1915 the first U.S. transcontinental phone

call was placed. According to AT&T, in 1945, a 10 minute evening phone call

between New York and Los Angeles cost $56.80 in 1995 dollars. By 1995, the

cost of this same call dropped to $1.50. At such a price, pre-World War II

conversations required good reasons to call. With today’s pricing, however,

people call anytime, just to talk. This drop in costs influences the extent to which

friendships can be sustained at a distance (Fischer, 1992). The first e-mail

message was sent in 1971 (Leiner et al., 2002) and the first of the IM programs,

ICQ (I seek you), was released in 1996 by Mirabilis (History of IM).

Scholars have argued that these media are not equally useful for building and

maintaining social relationships. In this section, we briefly review the empirical

evidence that suggests that these technologies differ in their usefulness for starting

and maintaining social relationship. We also identify three reasons why they

differ: (1) intrinsic properties of the media that influence both social presence and

how much information is exchanged during a communication session, (2) cost

structures that change how frequently people communicate over them, and (3)

features of the technologies and communication genres associated with them that

change the content of the communication.

A growing empirical literature examines the hypothesis that communication

modalities differ in their ability to support social relationships. Most of this

research compares text-based, computer-mediated communication with face-to-

face communication (e.g., Walther, 1995), although sometimes comparisons are

made to the phone as well. Cross-sectional research by Parks and Roberts (1998)

and by Cummings, Butler and Kraut (2002) have suggested that ties created or

primarily maintained online are of lower quality than those sustained through

other means. For example, Parks and Roberts (1998) surveyed respondents in an

electronic group about their relationships with another member of the group, as

well as with a matched person in their social network outside of the electronic

group. The authors found that respondents spent less time, were less

interdependent with, and were less committed to their on-line partner compared to

the off-line one. Cummings, Butler, and Kraut (2002) reported similar results.

They asked respondents to indicate how close they felt toward two different

people outside of the household. The first was the individual with whom they

communicated most often by e-mail, and the second was the person with whom

they reported communicating most using other modalities, including personal

visits and the phone. Respondents reported feeling significantly less close to the

e-mail partner.

816

In contrast to these survey studies, experimental studies suggest that social

relationships through computer-mediated communication can be as strong as

those that develop face-to-face, if participants are allowed to communicate for

enough time (Walther, 2002). McKenna (this volume) reports research showing

that cross-sex undergraduate pairs who met each another for the first time in an

Internet chat room tended to like one another more compared to those who met

face-to-face.

As these conflicting results demonstrate, social relationships that are maintained

using different communication media do not necessarily grow at the same rate or

to the same depth. Research currently presents no clear consensus about whether

one communication modality is better than another for the maintenance of social

relationships. The reason for these conflicting results may be that the

communication media themselves may inconsistently influence fundamental

communication variables; these variables may then mediate their influence on the

social relationships. In particular, the communication media may influence both

the frequency of communication sessions and the quality of communication

during a communication session.

Cost structures and the frequency of communication. Different communication

modalities impose both financial and behavioral costs, which are likely to affect

how frequently people use one or the other modality to communicate. For

example, telecommunication providers typically charge for each long distance

phone call based on distance and duration, while Internet service providers’ rates

for e-mail or instant message sessions are independent of distance and duration.

Previous research has shown that communication volume is highly sensitive to

these costs, and that people communicate substantially more when these costs are

reduced (e.g., see Mayer, 1977, Figure 7). The medium’s design affects the

behavioral cost of communication as well; for example, phones require

communicators to be simultaneously available before they can converse. To

overcome these limitations, people play “phone tag,” use answering machines to

convert synchronous to asynchronous communication, or they may restrict their

calling to known times of availability (Lacohee & Anderson, 2001). In contrast, e-

mail is asynchronous and does not require simultaneous availability. Yet another

medium, IM, requires simultaneous availability. Many IM applications (IM)

provide awareness services, which inform users when a potential partner is online

and available. In contrast to phone calls, however, the awareness services in IM

software help to synchronize the simultaneous availability of partners, and are

therefore likely to increase the frequency of communication.

Quality of communication. Communication media differ on the amount of

information they transmit and their interactivity, among other features (Clark &

Brennan, 1991). These features have implications for relationships that are

maintained using these media (Sproull, 1991). Social presence theory suggests

that media differ on the social presence that they afford; for example, face-to-face

communication provides more social presence than the phone, which in turn

818

provides more than text-based communication. The thesis is that media with more

social presence should be better at supporting social relationships (Short, 1976).

Although many scholars contrast computer-mediated communication to face-to-

face communication without differentiating among the varieties of text-based

communication, the degree of interactivity is likely to be especially important

both for language understanding in general (Clark & Brennan, 1991) and for

companionship (Rafaeli & Sudweeks, 1997). In contrast to the relatively

contemplative style of composing and reading e-mail messages, the

conversational style of an IM session makes the event more engaging and

analogous to “being with” a communication partner; i.e., IM offers more social

presence than e-mail. This interactivity encourages users to tailor messages to

particular recipients (Kraut, Lewis, & Swezey, 1982) and to use an informal of

communication style, making it easier for communicators to quickly repair

mistakes.

Media richness theory suggests that media can be differentiated on the number of

social cues that they convey, and their level of interactivity (Daft, 1984; Dennis &

Kinney, 1998). IM is richer than e-mail because it is more interactive. Among the

interactive media, face-to-face communication is richer than the phone, which in

turn is richer than IM, because both face-to-face and phone communications offer

more affective and interpretive cues such as tone of voice. These richer media are

better at reducing ‘uncertainty’ and ‘equivocality’ than leaner media such as IM

and e-mail; hence richer media are better suited to maintain relationships. Walther

(Walther & Parks, 2002) argues that because writing is slower than talking, less

information per unit time is conveyed in computer-mediated communication than

in face-to-face and phone conversations. As a result, people need more time to

develop relationships conducted over the Internet, although he argues that given

enough time, people can develop and maintain strong social relationships online.

In contrast to research suggesting that more social cues, social presence, and

interactivity are better for supporting social relationships, other researchers have

identified conditions under which fewer social cues, reduced social presence, and

less interactivity may be better. For example, Postmes and his colleague (Postmes,

Spears, & Lea, 1998, 2000) propose that the individuating information available

in rich communication media interferes with identification with a group as a

source of social influence. McKenna and colleagues (this volume) argue that the

lack of social presence and superficial social cues that are available in text-based,

computer-mediated communication allows individuals a better opportunity to

display and learn about each others’ true selves, and may be especially useful for

introverts or socially awkward individuals to slowly form social relationships,

without the pressures of face-to-face meetings.

Method

Overview

To examine the role of communication technologies in sustaining friendships, we

tracked high school students as they moved to college, a situation that places

existing social relationships at risk. As they move from high school to college,

students go from a secure world populated with high school friends who often

attend the same school and lived in the same town, to a world where these

relationships disperse as both the student and friends relocate. Relationships that

were once supported by geographic proximity are threatened. On the other hand,

new relationships form at the beginning of college, which are supported by

physical proximity; these new relationships may squeeze out the old ones. By

following the course of old high school and new college friendships, we evaluate

how communication in general, and different media in particular, facilitate the

development and maintenance of relationships.

This study had two samples, representing two different high school graduation

years. In both samples, we asked respondents at the end of high school to identify

up to 20 friends and acquaintances from high school; at end of their first semester

in college, those same respondents again identified up to 20 friendships that they

formed in college. Out of these, in the first group, we sampled 4 high school

friends and 4 college friends in the first sample; in the second group we sampled 3

high school friends and 3 college friends. Respondents reported on the frequency

of their communication with each relationship partner in-person as well as by

phone, e-mail, and IM, and their psychological closeness to that partner. We

followed these relationships for up to three years. We use hierarchical linear

growth models to examine the influence of time and communication frequency on

changes in psychological closeness.

Sampling respondents

We collected data from two samples of high school students. Sample 1 included

500 high school students who were admitted to Carnegie Mellon University

(Pittsburgh, PA) in the Spring of 2000, stratified by distance from home: 100

were students randomly selected within 15 miles of Pittsburgh, 100 were foreign

residents, and 300 were students randomly selected by U.S. zip code. Sample 2

included 500 high school students who were admitted to Carnegie Mellon in the

Spring of 2001, also stratified by distance from home: 100 students randomly

selected within 15 miles of Pittsburgh, 100 students randomly selected between

100-200 miles from Pittsburgh, 100 students randomly selected between 400-800

miles from Pittsburgh, 100 students randomly selected between 1700-5000 miles

from Pittsburgh, and 100 randomly selected international students. Participants

were sent a $2 bill before each survey was administered, and were entered into a

lottery for prizes after they completed the survey.

In each sample, survey data were collected during the spring of the students’

senior year in high school (June), at the end of their first freshman semester in

college (December), at the end of their freshman year (May), at the end of their

sophomore year (May), and for sample 1, the end of their Junior year (May). Of

the 1000 students initially invited to participate, 62.9% completed the first survey,

48.2% completed the second survey, 39.6% completed the third survey, 31.3%

孙家乐

822

completed the fourth survey, and 22.8% completed the fifth survey (sample 1

only).

Sampling relationships

We used name generators to sample the respondents’ high school and college

relationships. The purpose of the name generators was to elicit a wide variety of

social ties, from which we randomly selected individual relationships to follow.

We used this procedure rather than allowing respondents to nominate

relationships on their own, because the self-nomination would have restricted

variance on the outcomes of interest (i.e., psychological closeness). People tend to

select individuals who are emotionally close and currently provide support in their

lives (Burt, 1986). This selection on the dependent variable would either have

lead to regression towards the mean or made differences in changes in closeness

difficult to observe.

The name generators were phrased, “Think about relationships with specific

people in your (high school | college) social circle…(a) who provide you with

practical assistance, (b) with whom you discuss hobbies, sports, movies, and other

spare-time activities, (c) with whom you socialize, (d) who give you advice about

important issues, and (e) who are in the same organizations as you.” For each of

the 5 types of relationships, respondents entered up to 4 names along with the

gender and age of the tie.

823

Respondents used a web-based survey to complete the name generators; the

software then randomly selected a subset of the relationships that students

identified, stratified by gender. In Sample 1 were 4 high school relationships (two

males and two females) and 4 college relationships (two males and two females).

Sample 2 included 3 high school relationships (at least one male and at least one

female) and 3 college relationships (at least one male and at least one female). We

wanted to balance the gender of partners in order to broaden the kinds of

relationships studied, and again, to create variance on the outcome measures since

people, in general, feel closer to women than to men (e.g., Duck, Rutt, Hurst, &

Strejc, 1991; Wheeler & Nezlek, 1977). For the high school and college

relationships, respondents were asked whether each tie was a relative, romantic

partner, acquaintance, friend, close friend, or other. In the analyses reported

below, only acquaintances, friends, and close friends are included as “friends” to

avoid idiosyncrasies associated with relatives and romantic partner.

Measures

Psychological closeness. Though both samples used the same questions, response

options in Sample 1 during the first three time periods are slightly different than

those used in Sample 2 and the final two time periods in Sample 1. Closeness was

measured on a 5-pt scale with the question “How close do you feel to…”. In the

first sample (during Spring 2000, Fall 2000, and Spring 2001), the response

options only included (1) not very and (5) very, while in the second sample (and

during Spring 2002 and Spring 2003 in the first sample) the response options

824

included (1) Not at all, (2) Not too much, (3) Neutral, (4) Somewhat, and (5)

Very.

Time. The purpose of this paper is to examine how the relationship between

respondents and their partners change over time. We code time in months as the

interval between questionnaires: six months between the first three questionnaires

and 12 months thereafter. Time is 0 when a partner first appears in the data set,

i.e., at the initial questionnaire for high school friends and at the second

questionnaire for college friends.

Communication frequency. For each time period, respondents reported the

frequency with which they communicated with each partner (a) in-person, (b) by

phone, (c) by e-mail, and (d) by IM. They answered on 7-point Likert scales,

ranging from never to multiple times per day. For ease of interpretation, we

transformed the Likert scales to days per months of communication1. Overall

communication was the sum of communication across the four modalities. Since

our goal is to predict changes in psychological closeness among respondents and

their partners based on communication frequency, we use lagged communication

frequency to reduce ambiguity in making causal claims. That is, in the analyses

below, communication in the preceding time period predicts communication at

the subsequent time period, and changes in psychological closeness between the

two periods.

825

Analysis

In order to examine how communication using different technologies influences

changes in social relationships, we used hierarchical linear growth modeling, also

known as multi-level modeling (Bryk & Raudenbush, 1992; Singer & Willett,

2003). Multi-level modeling takes into account the non-independence of the data,

with each respondent describing multiple partners during multiple questionnaire

administrations. For the data described above, a 3-level model is required. In this

model, level 1 represents the respondent (e.g., the respondent’s sex, age, and

race), level 2 represents the relationship (e.g., partner’s sex and age,

communication frequency, and closeness with that partner), and level 3 represents

time (e.g., repeated observations).

In these analyses, the coefficients for time-invariant level 1 variables (e.g.,

respondents’ gender, age at the first time period, and race) and time-invariant

level 2 variables (e.g., partner’s gender and age at the first time period) represent

cross-sectional associations. The coefficients indicate whether, for example,

women report closer relationships with their partners on average than men, or

whether respondents report closer relationships on average with women partners

than males. The coefficients for time-varying level 2 variables (e.g., prior

frequency of communication with a partner) test whether communication predicts

subsequent psychological closeness. We can do this because, as shown below,

both the communication variables and the closeness variable are moderately

stable over time. The association of communication frequency with subsequent

826

closeness primarily represents the cross-sectional association of communication

and closeness.

The main effects and interactions with time represent the variables that predict

change in psychological closeness. The coefficient for the main effect of time

indicates the degree to which a participant’s closeness with a particular partner

changes over twelve months. A negative coefficient indicates a decline in

psychological closeness. The time X communication interactions indicate how

frequency of communication moderates the effects of time on changes in the

relationship. A positive coefficient for the interaction of time with communication

indicates that partners who communicate more have a slower decline in closeness.

We test the effects of communication frequency both for overall communication

and for the four modes of communication.

Results

Preliminary statistics. Combined descriptive statistics for respondents from

Sample 1 and Sample 2 are shown in Table 1. Approximately 51% of the

respondents were males; 30% were Caucasian, 30% were Asian, and they were 18

years old at the time of the first questionnaire. Of the friends and acquaintances

they described, 65% were from the high school years and 35% were added during

the first semester in college. All matched the respondents in gender and age.

827

At the time of the initial questionnaire, when friends and acquaintances were

initially described, respondents were communicating with them approximately 60

times per month or roughly twice a day. Participants communicated most with

those they felt closest to. The contemporaneous Pearson correlation between

overall communication with a partner and closeness to that partner, measured on

the same questionnaire was .41, p < .001.

[Insert Table 1 about here]

About half of this communication was conducted in-person (28 times per month),

with phone (15 times per month) and IM (15 times per month) occurring more

frequently than e-mail communication (9 episodes per month). Surprisingly, face-

to-face communication predicted closeness less well than phone, e-mail, or IM

communication: the contemporaneous correlation between closeness and

communication frequency was .10 for in-person communication, .41 for phone

communication, .35 for electronic mail, and .39 for IM. Presumably, this is

because phone, e-mail, and IM communication is primarily volitional (i.e., at least

one party intended the communication to occur), while in-person communication

is to a degree involuntary. Whether they wanted to or not, participants talked to

each other when they were in the same place (possibly to avoid being perceived as

rude).

828

All communication dropped over time, with the largest declines for face-to-face

communication. This supports our hypothesis that geographic distance affects the

patterns of communication in relationships (see Figure 1).

[Insert Figure 1 about here]

Table 1 also shows the inter-temporal stability of the time-varying measures:

communication frequency and psychological closeness. These were computed by

taking the Pearson correlation between the same variable measured on adjacent

questionnaires. The inter-temporal stability is moderate. Correlations for the

communication measures range from .44 to .49. Since the response rate to the

questionnaires dropped over time, this stability measure is most heavily

influenced by questionnaires early in the study. Because one might expect most

change in communication and relationships to occur during this period, this was

also the period that we sampled at 6-month intervals rather than yearly intervals.

The closeness that respondents expressed towards their partners also declined

across time (see Figure 2). Table 2 shows moderate stability in the measure of

psychological closeness, with the test/retest correlations being .65.

[Insert Figure 2 and Table 2 about here]

829

Predicting psychological closeness. Table 2 describes hierarchical linear growth

models, predicting psychological closeness with a partner from respondent

characteristics, partner characteristics, time, and overall communication

frequency. In these models, we standardized the psychological closeness variable,

with a mean of zero and a standard deviation of one. Thus we interpret the

coefficients as the extent to which a unit increase in an independent variable is

associated with psychological closeness, as measured in standard deviation units.

Model 1 examines the associations of psychological closeness with stable

characteristics of respondents and partners, and time. Older respondents reported

feeling less close to their partners than younger respondents felt to their partners

(and older respondents felt less close to older partners). In addition, respondents

reported feeling moderately closer to their high school friends than the ones they

met in college (by .3 standard deviation units). The highly reliable negative

coefficient for time confirms the pattern seen in Figure 2; respondents’ closeness

to their partners declines with time. On average, closeness to these friends and

acquaintances declines a fifth of a standard deviation per year. The non-

significant coefficient for the Time X Partner that was added in college indicates

that closeness diminishes approximately equally with time both for high school

and college friends, even though participants felt moderately closer to their high

school than college friends.

830

Model 2 in Table 2 adds the overall frequency of communication to the model.

The coefficient for lagged communication indicates that respondents felt closer to

partners with whom they had more communication in the previous time period.

Because communication frequency is measured on a log scale, the coefficient

means that respondents report feeling approximately 7% of a standard deviation

unit closer to partners with whom they communicate twice as frequently. The

positive Time X communication frequency interaction indicates that the decline in

psychological closeness is less for partners with whom respondents communicate

with more. Doubling communication with a partner reduces the decline in

closeness to that person by about 13% (ratio of the coefficients .026/.206).

[Insert Table 3 about here]

To predict psychological closeness, Table 3 decomposes the overall frequency of

communication into the modalities through which it occurs. We use the same

analysis framework as in Table 2 (Model 2), except that we include the

communication frequency for the four communication modalities in place of

overall communication frequency. The coefficients for the main effects of the

communication are in Table 3, Model 3; all are positive and significantly greater

than zero. This pattern indicates that respondents feel closer to friends with whom

they communicate using each of the four modalities. Differences in the size of the

coefficients are instructive. The coefficient for phone communication is twice is

high as the coefficients for e-mail and IM, the two computer-mediated

831

communication modalities. These results suggest that respondents are more likely

to talk by phone to those with whom they feel closer, than to communicate to

those same partners with either e-mail or IM. The two computer-mediated

communication coefficients in turn are twice as high as that for in-person

communication, again reflecting the frequent non-volitional nature of in-person

communication.

Model 4 in Table 3 adds the Time X Communication interactions to examine the

association of communication with changes in closeness. The positive coefficients

for both e-mail and IM suggest that communication using these modalities

reduces the decline in closeness. Doubling e-mail communication with a partner is

associated with a 34% reduction in the decline in closeness with that partner

(.036/.104). Similarly, doubling IM communication with a partner is associated

with an 18% reduction in the decline in closeness with that partner (.020/.104).

Predicting communication. The longitudinal results in Tables 2 and 3 are

consistent with the claim that communication prevents declines in psychological

closeness. However, to examine the causal direction in more detail, we conducted

supplementary analyses predicting changes in communication from closeness.

Table 4 presents results from hierarchical linear growth models that predict

frequency of communication (in the log scale) based on time, psychological

closeness at the prior time period, and their interactions. Stable characteristics of

the respondents and their partners were included as control variables. Overall,

832

during their college years, respondents communicated 175% more with partners

whom they added during college than with their high school friends. This

difference depended on the media that respondents selected. The gap was largest

for in-person communication and phone communication than for e-mail and IM.

[Insert Table 4 about here]

Consistent with Figure 2, the analyses show that overall communication drops

with time by about 43%, and that this effect is larger for in-person than for other

types of communication. Consistent with the correlations between closeness and

communication frequency that were reported previously, the multivariate analyses

show that students communicate more across all modalities with partners with

whom they felt closer in the previous time period.

The interactions between time and psychological closeness are the most

interesting results to assess the direction of the causal link between

communication and closeness. The non-significant interaction between time and

psychological closeness for overall communication suggests that respondents’

preexisting closeness with a partner does not mitigate the drop in communication.

The time and psychological closeness interactions were non-significant for both e-

mail and IM, again suggesting that respondents’ preexisting closeness with a

partner does not mitigate the drop in computer-mediated communication. The

positive time and psychological closeness interaction for in-person

communication suggests that prior closeness mitigates the drop in face-to-face

833

communication. We speculate that this result occurs because students make an

effort to see only their closest friends when they return from school for breaks or

summer vacation. In contrast, the negative interaction for phone communication

suggests that the drop in calls is especially steep for partners with whom the

respondent had previously felt very close. We speculate that financial costs force

students to refrain from calling once-close friends; people whom they called

frequently when they lived in the same town and attended the same school.

Discussion

Our findings indicate that when students move from home to college, they reduce

both their communication with their high school friends and their closeness, that

sense of psychological connection. This same effect occurs with new friends that

students make during their first semester in college as they get further into their

college career. The purpose of this paper was to see how these factors were

causally related, and to assess whether modern telecommunication technologies

change the risk to relationships that distance and time can introduce.

To summarize the main results, longitudinal analyses show that although

psychological closeness to high school and college friends declines with time, this

decline is less steep among pairs who communicate more. This pattern is

consistent with Duck’s hypothesis (1998) that communication can mitigate the

centripetal forces causing social relationships to split apart. Surprisingly, when we

looked at the influence of different communication modalities, communication by

孙家乐
孙家乐
孙家乐
孙家乐

834

e-mail and IM seem to retard the drop in closeness, but communication in-person

and by phone do not. This pattern of interactions occurs even though phone

communication is the technology that best predicts psychological closeness at any

given time.

Why do computer-mediated communications seem to guard against the disruption

of social relationships more than in-person and phone communication for these

students? This finding is inconsistent with some of the literature reviewed in the

introduction which focused on the media’s respective intrinsic properties. Both its

media richness and social presence suggest that communicating by phone would

be most useful for guarding against threats to relationships.

Why does closeness drop least among partners who regularly use e-mail and IM?

One possibility is that frequency of communication for computer-mediated media

is less affected by distance than communication by phone. The technological

advantages of computer-mediated communications are irrelevant in mitigating

distance as a factor; rather, this advantage is simply the result of government

regulations and corporate marketing decisions. Unlike traditional long distance

phone providers, Internet service providers do not charge more to send data

packets across town or across the country. Moreover, pricing schemes used by

long distance carriers are not fixed. This may change, however, if Internet phone

technologies become more popular since the Internet is regulated less by the

孙家乐

835

Federal Communications Commission and state agencies than are conventional

phone services (E.g., Federal Communications Commission, 2003).

One strength of our research is the use of longitudinal data, which enabled us to

follow relationships over time. As a result, we were not constrained by the

ambiguities inherent in cross-sectional analyses of how strong ties were at a single

point in time. For example, the cross-sectional results suggest that communication

by phone is the strongest predictor of psychological closeness with a

communication partner. This result is consistent with predictions from media

richness and social presence theories; i.e., that richer and more interactive media

will better support social relationships. However, the cross-sectional results are

also consistent with an alternative explanation: students primarily call people with

whom they feel close, while they are more careless with their computer-mediated

communication. The longitudinal results tell a different story. They show that

communication over a computer is associated with less erosion in social

relationships, while communication by phone is not. Our conclusion from this

pattern of results is that communication frequency, not communication quality, is

the important element that sustains relationships; we also conclude that for

economic reasons, the frequency of communication by phone is especially

sensitive to distance, while communication by computer is not.

One weakness in this research is the lack of an identifiable mechanism for why

different communication technologies had varied effects on relationship

孙家乐
孙家乐

836

maintenance. It is likely that norms of communication technology use contribute

to how a change in that communication will influence the relationship. For

example, the norm among some high school students is to congregate on IM at

specified times in the evening to “hang out” with friends, whereas college

students tend to make themselves available whenever their computers are

connected to a network. These norms of availability can shape how just one

computer-mediated communication, IM, influences relationship maintenance.

Future research would benefit from measuring communication norms. Students

may believe that regular use of a particular media, regardless of content, can

sustain a relationship at the desired level of closeness and support.

Equally important, the communication content that is exchanged over different

media will undoubted influence how a communication change influences

relationships. As Lacohee and Anderson (2001) note, phone conversations are

often used to exchange social support, especially among women (see also Boneva

& Kraut, 2003). In contrast, as Boneva and colleagues (this volume) note, much

of IM communication is used for exchanging chitchat, and social support is rare.

An obvious issue raised by the discussion of maintaining personal relationships

during the transition from high school to college is whether or not there are

academic consequences. Are students more likely to stay in college when

relationships are maintained successfully? Do students perform better in their

courses? Is college more satisfying for them than high school? We do not have

孙家乐

837

answers to these questions, but would speculate that personal relationships

contribute to a positive quality of life for students in college.

Summary. For students who move off to college, the ties with their high school

friends and the friends that they make their first semester in college are fragile.

On average, these relationships decline with time. Consistent with an enactment

model of relationship, however, communicating with these friends prevents the

relationships from declining as swiftly as they otherwise would. Communication

seems to inject energy into a relationship and prevents it from going dormant. In

contrast, simply feeling close to these friends does not prevent the communication

from declining.

E-mail and IM seem to be the telecommunication technologies that are especially

useful for maintaining friendships among young adults. The utility of these

technologies may not stem from their intrinsic features, for example, their

interactivity, media richness, the effort needed to type messages, or their ability to

convey social presence. Rather, we suspect that arbitrary economic decisions may

be more important. Unlike the phone, which costs more when talking longer to

someone farther away, pricing for the computer-mediated communication

technologies does not depend upon either the length of a message or the distance

it must travel.
