ABSTRACT—There are growing levels of chaos in the lives
of American children, youth, and families. Increasingly,
children grow up in households lacking in structure and
routine, inundated by background stimulation from noise
and crowding, and forced to contend with the frenetic pace
of modern life. Although widespread, chaos does not occur
randomly in the population. We document that low-income
adolescents face higher levels of chaos than their more af-
fluent counterparts and provide longitudinal evidence that
some of the adverse effects of poverty on socioemotional
adjustment are mediated by exposure to chaotic living
conditions.
There is widespread evidence of growing levels of chaos in
the lives of American children and youth (Bronfenbrenner,
McClelland, Wethington, Moen, & Ceci, 1996). The amount of
time parents can devote directly to their children is declining
precipitously as more hours are spent away from home, working,
commuting, and delivering children to and from child care,
school,andotheractivities;familiesarelesslikelytosharemeals
and otherritualstogetherasdomestic time becomes compressed;
more and more children live in crowded, noisy, and substandard
housing; and increasingly, family members characterize home
life as hectic, unstructured, unpredictable, and, at times, simply
out of control. Although such trends are ubiquitous, chaos is not
evenly distributed in the population. Low-income families are
more likely to face chaotic living conditions than are their mid-
dle- and upper-income counterparts. In this article, we bring
together two strands of thinking about risk factors in human de-
velopment to examine the role of chaos in poverty’s adverse im-
pacts on children’s socioemotional adjustment.
In the bioecological model of human development, Bronfen-
brenner (Bronfenbrenner & Evans, 2000) offers the following
proposition:
Throughout the life course, human development takes place
through processes of progressively more complex reciprocal in-
teractions between an active, evolving biopsychological human
organism and the persons, objects, and symbols in its immediate
externalenvironment.Tobeeffective,theinteractionmustoccuron
a fairly regular basis over extended periods of time. Such enduring
formsofinteractionintheimmediateenvironmentarereferredtoas
proximal processes. (p. 117)
Chaosmayinterferewiththedevelopmentandsustainabilityof
proximal processes because it shortens their duration and in-
creases interruptions, rendering exchanges of energy between
thedevelopingchildandherorhissurroundingslesspredictable.
Chaos may also lower the intensity of proximal processes, given
stress and fatigue in parents and other caregivers who must also
contend with chaos. Frenetic activity, lack of structure, and un-
predictability, in conjunction with intense background stimula-
tion, take their toll by depriving the developing organism of the
kinds of well-structured, predictable, and sustained exchanges
of energy with the persons, objects, and symbols in the immedi-
ate environment critical to fostering and sustaining healthy
development (Bronfenbrenner & Evans, 2000; Bronfenbrenner
& Morris, 1998).
Chaotic living conditions might also interfere with the devel-
opment of competency, the belief that one is an effective agent in
coping with one’s surroundings (White, 1959). Unpredictable,
nonroutine, inconsistent, and noncontingent physical and social
surroundings can interfere with a sense of mastery and lead to
helplessness in the developing person. Lack of routines and
structureandlargelyintractablestimulationmayalsoundermine
the child’s ability to self-regulate and manage his or her own
behaviors and emotions.

Lack of routines, structure, and rituals in the home has been
shown tobe negatively associated withpsychological adjustment
in children and adolescents, parental competency ratings, sat-
isfaction with family, and school achievement (Fiese et al., 2002;
Repetti, Taylor, & Seeman, 2002). Noise, crowding, and poor
housing quality are positively associated with children’s psy-
chological distress (Evans, 2001; Evans, Wells, & Moch, 2003;
Wachs & Corapci, in press), as well as learned helplessness
(Cohen, 1980; Evans & Stecker, 2004).
POVERTY, CHAOS, AND SOCIOEMOTIONAL ADJUSTMENT
The immediate living environment of many low-income families
can be fairly characterized as chaotic, consisting of numerous
intractable and unpredictable conditions (Bronfenbrenner et al.,
1996; Evans, 2004; McLoyd, 1998; Repetti et al., 2002; Sher-
man, 1994; Taylor, Repetti, & Seeman, 1997). Low-income
children and youth face a bewildering array of suboptimal,
chaotic living conditions. Relative to their more affluent coun-
terparts, they reside inmorecrowded, noisier,and poorer-quality
housing (Evans, 2004; Saegert & Evans, 2003). Poor children
must also contend with less structure, routine, and predictability
in their daily home life (Brody & Flor, 1997; Jensen, James,
Boyce, & Hartnett, 1983; Matheny, Wachs, Ludwig, & Phillips,
1995). Thus, chaos is a plausible mechanism to account for the
adverse impacts of poverty on socioemotional adjustment.
Numerous studies have documented negative relations be-
tween household income and psychological distress in children
and adolescents (Bradley & Corwyn, 2002; Duncan & Brooks-
Gunn, 1997; Grant et al., 2003; Luthar, 1999; McLoyd, 1998).
Grant et al. found an average effect size of .22 for internalizing
symptoms and .17 for externalizing symptoms across 46 studies
of children and poverty. Cross-sectional and longitudinal results
converged. Moreover, the longer the duration of exposure to
poverty, particularly in early childhood, the greater the adverse
impact (Bradley & Corwyn, 2002; Duncan & Brooks-Gunn,
1997; Luthar, 1999; McLoyd, 1998).
Although no researchers have directly investigated poverty
and learned helplessness, a few have shown that lower socio-
economic status (SES) is associated with diminished mastery
beliefs in children (Bandura, Barbaranelli, Caprara, & Pastor-
elli, 2001; Battle & Rotter, 1963). Low-SES parents discourage
self-directedness in their children (Kohn, 1977) and are more
restrictive than high-SES parents (Luster, Rhoades, & Haas,
1989); these trends, in turn, lead to lower self-efficacy among
low-SES adolescents (Whitbeck et al., 1997).
Children’sself-regulatoryabilitymay beinfluencedbypoverty
as well. Studies have shown that income is positively associated
with maternal and teacher ratings of self-regulatory behavior
among 6- through 9-year-olds (Brody, Flor, & Morgan Gibson,
1999) and with delay of gratification among third through fifth
graders(Evans&English,2002).Moreover,Lengua(2003)found
that self-regulatory ability in third through fifth graders buffered
some of the ill effects of multiple risk exposure on psychological
distress.
Three studies provide more direct evidence that chaos may
account for some of the ill effects of poverty on children. In a
study of inner-city 8- to 12-year-olds, Kliewer and Kluger (1998)
discovered that children with regular and predictable house-
holdroutineswere buffered from theharmfuleffects ofhassles on
adjustment. Bresnahan and Blum (1972) studied concept for-
mation in low- and middle-SES 7-year-olds who were asked to
discover what combination of color and form was correct (e.g.,
triangle on green background). The children initially received
either 0, 6, or 12 trials of random feedback (acquisition phase)
and then received accurate, contingent feedback on each test
trial. When there was no initial random feedback, low-SES
children had a 15% error rate on test trials, and high-SES chil-
dren had a 5% error rate. However, when noncontingent, random
feedback (6 or 12 trials) was given during the acquisition phase,
low- and high-SES children had the same error rate, 15%, at test.
In a third investigation, parenting practices (a latent construct
including mother-child harmony, maternal involvement in
school, and maintenance of household routines) significantly
mediated the effects of poverty on cognitive and emotional
competency (Brodyetal., 1999).These three studies suggestthat
chaos could convey some of the harm associated with childhood
poverty.
SUMMARYAND HYPOTHESES
There are growing levels of chaos in the lives of many children.
Chaos, however, is not randomly distributed in the population.
Low-income households experience a disproportionate share of
chaotic living environments characterized by high levels of am-
bient stimulation (e.g., noise, crowding), minimal structure and
routine,andconsiderableunpredictabilityandconfusionindaily
activities. Such conditions have been linked to psychological
distress in the developing person. Furthermore, poverty is neg-
atively associated with good adjustment in children.
Thus, we hypothesized that compared with middle-income
adolescents, low-income adolescents experience greater chaos
and manifest more socioemotional distress. Moreover, we hy-
pothesized that exposure to chaos accounts for some of the
elevation in socioemotional distress among lower-income ado-
lescents. To assess these two hypotheses, we incorporated mul-
tiple indicators of socioemotional distress into a longitudinal
study.
METHOD
Participants
Three hundredthirty-ninechildrenparticipatedinWave1ofthis
study when they were in Grades 3 through 5 (M 5 9.2 years, 51%
male). Three to 4 years later, 223 of these same children were
Volume 16—Number 7 561

reevaluated(Wave2)whentheywereinGrades7and8(M513.1
years, 52% male). All of the families in the sample lived in rural
areas in upstate New York. They were recruited from public
schools, New York State Co-Operative Extension programs, and
variousantipovertyprograms(refusalrateinWave1waslessthan
5%).Low-income families were oversampled (53%) because this
research program focuses on rural poverty. The mean income-to-
needs ratio was1.66atWave1and2.34atWave2.Thisratioisan
annually adjusted, per capita index, comparing household in-
come with federal estimates of minimally required expenditures
for maintaining a household. Only one child per household par-
ticipated in the study. The sample was predominantly White
(94%), reflecting the demographics of rural upstate New York.
The mean income-to-needs ratio at Wave 1 was 1.81 for chil-
drenwhoremainedinthesampleatWave2and1.41forthosewho
did not participate in the second wave, t(338) 5 3.24, p < .01.
ChildrenwholeftthesamplebythetimeofWave2datacollection
were disproportionately from low-income families. None of the
outcome measures, however, were related to attrition.
Procedure
All data were collected with a standardized protocol in partici-
pants’ residences (see Evans, 2003, for more details).
Chaos
Chaos was assessed with a standard scale that possesses excel-
lent reliability and converges with independent ratings of noise,
crowding, foot traffic, and confusion in the home (Matheny et al.,
1995). We added items to increase coverage of routines and rit-
uals in the home (a for revised chaos scale 5 .77). These addi- tional items came from the Family Ritual Questionnaire (Fiese &
Kline, 1993) and the Family Routines Inventory (Jensen et al.,
1983). For this measure of chaos, the mother answered ‘‘true’’ or
‘‘false’’ to statements describing environmental stimulation
(‘‘Youcan’thearyourselfthinkinourhome’’),confusion(‘‘Wecan
usuallyfindthingswhenweneedthem’’),andritualsandroutines
(‘‘[Target child] does his[her] homework at the same time each
day’’). Chaos, unlike all other measures we report here, was as-
sessed only at Wave 2.
Learned Helplessness
In Wave 2, learned helplessness was evaluated with a standard
behavioral protocol (Glass & Singer, 1972) adapted for children
(Bullinger,Hygge,Evans,Meis,&vanMackensen,1999;Cohen,
Evans,Stokols,&Krantz,1986).Thechildwasshownapictureof
a tangram and instructed to reproduce the illustration with
multiple plastic pieces that fit into a rectangular frame. The child
could work on the puzzle until it was solved or until he or she felt
unabletosolveit.Atthatpoint,thechildcouldmoveontoanother
tangrampuzzle.Oncethechildmovedontothesecondpuzzle,he
or she could not return to the first puzzle. The child received the
first test puzzle after the experimenter ensured that he or she
comprehended the task. Unbeknownst to the child, this first
problem was unsolvable. The second puzzle was solvable. A total
of 15 min was available for the two test puzzles. The number of
seconds the child persisted on the first puzzle was the index of
learned helplessness. This learned-helplessness measure is re-
lated to beliefs about personal control, experimental manipula-
tions of control, and chronic exposure to uncontrollable stressors
(Cohen, 1980; Cohen et al., 1986; Evans & Stecker, 2004; Glass
&Singer,1972).LearnedhelplessnesswasassessedinWave1by
giving children 10 min to draw linkages between familiar pic-
tures without doubling back or lifting their pencil. Time spent
working on the first problem, which could not be solved, was the
measure of learned helplessness. Children were also given a
second, solvable problem to work on (Evans, 2003).
Psychological Distress
Psychological distress was measured in Wave 1 using the Rutter
Child Behavior Questionnaire (Rutter, Tizzard, & Whitmore,
1970) and in Wave 2 using the Youth Self Report instrument. The
Youth Self Report has excellent reliability and has undergone
extensive validation across a wide range of samples, 11 through
18 years of age (Achenbach, 1991). On a scale from 0 (not true) to
2 (very true or often true), participants answer whether symptoms
describethem.Thesesymptomsinclude‘‘Ifeellonely,’’ ‘‘Iworrya
lot,’’ and ‘‘I get in many fights.’’ We combined internalization and
externalization symptoms into one scale because the overall
scale was reliable (a 5 .93), the two subscales were intercorre- lated (r 5 .70), and the Rutter Child Behavior Questionnaire
combines both types of symptoms.
Self-Regulatory Behavior
For Wave 1, a behavioral measure of delayed gratification was
used to assess self-regulatory behavior (Evans, 2003). Self-reg-
ulation was assessed in Wave 2 with the Children’s Self-Control
Scale (Humphrey, 1982). The children’s English teachers rated
their behaviors on a 5-point rating scale (from never through al-
most always true). Examplesof itemson this scale are ‘‘This child
thinksaheadoftimeabouttheconsequencesofhisorheractions’’
and ‘‘This child sticks to what he or she is doing, even on long,
unpleasant tasks, until finished.’’ The scale has excellent relia-
bility (a 5 .91 in the present study) and has been validated against multiple criteria (Humphrey, 1982).
RESULTS
Cross-Sectional and Longitudinal Analyses
Longitudinal analyses regressed socioemotional outcomes onto
income-to-needs ratios at Wave 2 (Grades 7–8), controlling for
the respective Wave 1 (Grades 3–5) outcome. In addition to these
longitudinal results, we report cross-sectional data from Wave 1.
For descriptive purposes, Table 1 reports means and standard
errors for the Wave 2 sample split into poverty and middle-in-

come groups. However, all inferential analyses maintained the
continuous nature of the income-to-needs variable.
Income predicted learned helplessness among the middle
school youth when learned helplessness at Wave 1 was statisti-
cally controlled, b 5 31.03, t(219) 5 2.33, p < .02, f 2 5 .02.
These longitudinal findings replicate the cross-sectional asso-
ciation between income-to-needs ratio and learned helplessness
at Wave 1, b 5 22.91, t(276) 5 2.35, p < .02, f 2 5 .03.
The youths’ self-report of psychological distress was signifi-
cantly affected by income, statistically controlling for Wave I
distress, b 5 �0.86, t(220) 5 2.50, p < .01, f 2 5 .03. At Wave 1, income-to-needs ratio was also significantly related to psycho-
logical distress, b 5 �1.99, t(337) 5 6.55, p < .01, f 2 5 .14. Teachers’ ratings of self-regulatory behavior were also signif-
icantly related to income when Wave 1 self-regulatory behavior
was controlled statistically, b 5 1.14, t(120) 5 2.70, p < .01,
f 2 5 .05.
1 There was also a significant relation between income
and self-regulatory behavior at Wave 1, b 5 112.35, t(199) 5
3.41, p < .01, f 2 5 .07.
Chaos as a Mediator of the Relation Between Poverty and
Socioemotional Development
In order to examine whether each of the longitudinal effects of
income-to-needs ratio on socioemotional development was me-
diated by chaos, we conducted a series of hierarchical regression
equations. As shown in Table 2, the first equation regressed
learnedhelplessnessontoincome-to-needsratioatWave2.(Note
that in all the analyses reported in Tables 2 through 4, the re-
spective Wave 1 outcome measure was included as a statistical
control.)ThesecondlineofTable2showstheresultsofregressing
learned helplessness onto chaos, the hypothetical mediator, and
thethirdlineshowstheresultsofregressinglearnedhelplessness
onto income-to-needs ratio after controlling for chaos. Of par-
ticularinteresttothemediationalhypothesisisthechangeinDR2
from row 1 (DR2 5 .02) to row 3 (DR2 5 .01). The significant DR2
for income-to-needs ratio in row 1 becomes statistically nonsig-
nificant in row 3, after chaos is partialed out. Note also the 26%
shrinkage in the beta weight ( p < .05) for income-to-needs ratio
after chaos waspartialedout(row 1:b 531.03,row3:b522.88).
Thus, the significant effect of income on learned helplessness
was attenuated once chaos was controlled for. Income levels
were significantly related to chaos, b 5 �0.85, t(223) 5 4.65, p < .0001.
Table 3 depicts the parallel set of hierarchical regression
equations for psychological distress. As in the analysis for
learned helplessness, the statistically significant, longitudinal
effect of income-to-needs ratio on psychological distress be-
came nonsignificant, and the beta weight shrank significantly
( p < .05), after chaos was partialedout.The longitudinalrelation
between income and psychological distress was mediated
by chaos.
The results for teachers’ ratings of self-regulatory behavior
(Table 4) are similar. The statistically significant longitudinal
effect of income on self-regulatory behaviors was significantly
attenuated ( p < .01) when chaos was partialed out.
DISCUSSION
A healthy childhood environment requires regularity, consis-
tency, predictability, and controllability. In order for proximal

processes to be effective, they need to occur in a predictable
manner, with some intensity over time, and with minimal inter-
ruption (Bronfenbrenner & Evans, 2000; Bronfenbrenner &
Morris, 1998). The immediate surroundings of low-income ado-
lescents are more chaotic, consisting of noisier, more crowded,
more frenetic, and less structured and predictable routines of
dailyliving,thanarethehouseholdsofwealthieradolescents(see
Table 1). Moreover, these chaotic conditions convey some of the
adverse, longitudinal effects of poverty on children’s socioemo-
tional development (Tables 2–4). The longitudinal research de-
sign of this study, coupled with the cross-sectional replications
plus multiple measures of socioemotional adjustment, lend
confidence to these conclusions.
Study Limitations
More low-income children than middle-income children left the
sample between the first and second waves. Although none of the
socioemotional outcomes showed selective attrition, concerns
remain. For example, perhaps selective attrition biased our re-
sultsbecausefamilieswhomovedorcouldnotbecontactedagain
dealt with more chaos than those who remained in the sample. A
related drawback is the absence of a chaos measure in Wave 1.
Because we learned of the chaos index following Wave 1, we
could not examine whether greater chaos was associated with an
increased likelihood of dropping out of the sample. The absence
ofaWave1chaosmeasurealsoprecludedourexaminingwhether
changes in chaos over time explain changes in the outcome
measures, which would have provided a more rigorous media-
tional test. Furthermore, although it is valuable to study rural
poverty given researchers’ nearly exclusive focus on inner-city
deprivation, there may be critical aspects of inner-city chaos not
captured in this study.
Poverty, Self-Regulatory Behavior, and Learned
Helplessness
In addition to showing that poverty is directly related to chaos,
which, in turn, conveys some of poverty’s impact on socioemo-
tional development, the present study broadens the literature on
chaos. Prior studies have relied primarily on self-reported out-
comes, whereas we included a behavioral measure and teachers’
ratings. Also, this is the only longitudinal study of household
chaos and children’s well-being (Fiese et al., 2002; Repetti et al.,
2002; Wachs & Corapci, in press). Furthermore, we have
broadened the measurement of chaos by employing a multidi-
mensionalindexthatincorporatesassessmentofnoise,crowding,
confusion, and lack of structure and routinesin the households of
children and youth.
The learned-helplessness and poverty data are also notewor-
thy, given prior work showing negative associations between
parentalSES and children’scontrol beliefs (Bandura etal.,2001;
Battle & Rotter, 1963), as well as parenting practices that en-
courage self-directedness (Kohn, 1977; Luster et al., 1989). We
build on this literature in two respects. First, our findings are
longitudinal, and second, we demonstrate a link between poverty
and an overt, behavioral index of learned helplessness rather
than strictly subjective ratings. The present findings are also
noteworthy in light of previous research showing that exposure to
uncontrollableenvironmentalstressorssuchasnoiseorcrowding
induces learned helplessness in humans (Cohen, 1980; Evans &
Stecker, 2004).
Thereiswidespreadevidenceofchaosanddisarrayinthelives
of contemporary American children and youth, particularly
among economically disadvantaged families. Levels of chaos are
accelerating and pushing beyond the confines of poverty into
middle- and upper-income families. Scholars and policymakers
alike need to attend to these trends and contemplate their im-
plications for future generations.
