Outcome Research Design
A Best Kept Secret: Single-Subject Research Design in Counseling
Linda H. Foster1
Abstract Since the beginning of the counseling profession, there have been calls for counselors to support their effectiveness with clients in various counseling settings. Research methods that emphasize the individual do exist; however, professional counselors are reluctant to document their work through research. Single-subject research design methods help counselors report their client work and show effectiveness of counseling. More importantly, single-subject research provides counselors with a scientific method of inquiry to examine counseling techniques and ultimately help their clients.

In response to demand to provide evidence of
the effectiveness of counseling (Astramovich,
Hoskins, & Erford, 2008; Lundervold &
Belwood, 2000; Sheperis & Miller, 2008), there
is a renewed interest in the professional counsel-
ing community appealing to counselors for more
research to provide evidence of the effectiveness
of therapeutic interventions (Foster, 2009;
Ray, Minton, Schottelkorb, & Brown, 2010;
Sharpley, 2007; Sheperis, Sheperis, & Simpson,
2010; Sheperis & Miller, 2008). Ray, Minton,
Schottelkorb, and Brown (2010) urged counse-
lors to conduct empirically based research in
order to comply with ethical codes not merely for
the sake of compliance but in order to contribute
to the professional knowledge base, thereby
enhancing client wellness. Nevertheless, there
appears to be a lack of enthusiasm for outcome
research by counselors in school counseling,
career counseling, and clinical counseling
(Foster, Watson, Meeks, & Young, 2002; Hinkle,
1992; Huber & Savage, 2009; Lundervold &
Belwood, 2000; McDougall & Smith, 2006;
Reisetter et al., 2004).
The intensive study of one individual, as in
the case of single-subject research, is appropri-
ate for professional counselors working with
individuals and couples. This idea is rooted
in the early 1900s when the individual case
study was widely recognized as the accepted
methodology for investigating emotional and
behavioral problems within the field of psy-
chiatry and psychology (Heppner, Kivlighan,
& Wampold, 2008). Barlow and Hersen
(1976, 1984) noted that study of the individual

was paramount for studying human behavior
change. They cited several advantages to this
case study approach including advancing clini-
cal innovation, development and refinement of
technical skills, among others. Studying the indi-
vidual and the effectiveness of the counselor’s
interventions can be accomplished with single-
subject research and also provide a culturally sen-
sitive research tool (Lundervold & Belwood,
2000; Sheperis et al., 2010).
Early case studies were not tightly controlled
and therefore as the professions of psychiatry
and psychology developed, more rigorous
methods of research regarding the efficacy of
therapy developed, but these methods relied on
group findings rather than individualist results.
There have been continued calls for outcome
research by professional counselors utilizing
an individual perspective, and fortunately
individualized research has been used since
the beginning of our profession. Barlow and
Hersen (1976, 1984) acknowledged the lack of
an adequate research method to document
individualist behavior change: dissatisfaction
with some of the early appraisal methods and
criticism of the measurement techniques led
researchers to investigate additional research
methods, and through the next several decades
the development and strengthening of applied
research methods continued.
There may be a myriad of reasons for the
lack of outcome research but one reason
mentioned by Lundervold and Belwood (2000)
is the perception that counseling and research
are antithetical. Other reasons suggested in
professional literature include a lack of knowl-
edge and training in research methods, legal and
ethical considerations regarding minors, time
constraints, and not surprisingly, a lack of
confidence (Fairchild, 1993; Fairchild & Zins,
1986; Myrick, 1997). Hinkle (1992) asserted the
absent outcome research is due, in part, to the
lack of practical methodologies and overreli-
ance on statistical rather than clinical signifi-
cance. Sheperis and Miller (2008) agreed that
clinical significance is more interesting, appro-
priate, and useful to counseling practitioners than
statistical significance. Therefore, single-subject
research design (SSRD) methodologies are better
suited for counseling practitioners to document
their work and provide evidence of the effective-
ness of counseling. Increasingly, SSRDs are
being promoted because of the applicability to
practice settings and the ability to easily incorpo-
rate into a client’s treatment (Ray et al., 2010;
McDougall & Smith, 2006; Sharpley, 2007).
Consequently, the focus of this article is to assist
counseling professionals and counselor educa-
tion students in gaining an understanding of the
usefulness of SSRD methodology.
SSRD Description
Simply defined single-subject research metho-
dology allows for the study of one individual
or one group that is treated as a single entity
(Foster, 2009). More formally defined, SSRD
examines variables that may change over time
within an individual subject (Heppner et al.,
2008). An essential feature of single-subject
research is systematic, repeated, and multiple
observations over time of a client, dyad, or group.
Client behaviors measured may range from overt
to covert behaviors (e.g., self-mutilation or
self-defeating thoughts). SSRD allows counse-
lors to research behaviors and interventions with
an individualized focus.
SSRDs, also known as time series designs or
equivalent time series designs, are quasi-
experimental designs. Unlike true experimental
designs, they do not use a formal control
group. Rather, they use the subject as his or her
own experimental control. SSRD examines
the change in a client’s or group’s behavior
(dependent variable) following a counselor’s
intervention (independent variable). As an exam-
ple, the counselor can use SSRD to determine
whether a change occurred in a client’s stress
level, but the possibility exists that other variables
also influenced the change. A simple A-B design
cannot unequivocally prove that the counselor’s
intervention was responsible for the change. The
counselor’s intervention may have been responsi-
ble for the observed change, but there may be
other extraneous conditions that also influenced
the client’s change. In research parlance, the
researcher cannot eliminate or rule out threats
to the internal validity. The practical or clinical
Foster 31
significance may outweigh the lack of statistical
significance if the client improves. In order to
determine whether the client change was due
solely to the counselors intervention, the inter-
vention must be replicated a second time. Repli-
cation should only be used if a return to the
baseline would not endanger the client.
Although professional counselors have been
resistant to conduct outcome research, SSRDs
can offer professional counselors a method to
evaluate, document, and communicate their
work to clients as well as provide needed data
to enhance evidence-based practice. De Los
Reyes and Kazdin (2008) noted evidence-
based practice encompasses many disciplines
from medicine and education to psychology
and counseling and beyond. Researchers offer
SSRD as a method to carefully explore charac-
teristics of therapeutic relationships (see Foster
et al., 2002; Heppner et al., 2008; Hinkle, 1992;
Lundervold & Bellwood, 2000; McDougall &
Smith, 2006; Ray et al., 2010; Sheperis & Miller,
2008). Many professionals have already adopted
SSRDs including special education teachers,
school psychologists, and therapeutic recreation
therapists because of the low data collection
costs, lack of complicated statistics, and ability
to assess individualized interventions (De Los
Reyes & Kazdin, 2008; Foster, 2009).
Heppner, Kivlighan, and Wampold (2008)
have long touted the benefits of using SSRDs.
The simplicity of SSRDs can be used to test new
theories or interventions or can be used to dis-
cover new information which can be very helpful
with clients. Many professionals (e.g., school
counselors, therapeutic recreation therapists,
special education teachers, and school psycholo-
gists) use SSRDs because of low data collection
costs and ease of uncomplicated statistics and
individualized approach. Additionally, for pro-
fessional counselors who work within a managed
care environment, providing evidence of effec-
tiveness or outcome research is a prime reason for
utilizing SSRDs (Sheperis & Miller, 2008).
Classic SSRD Designs
SSRDs involve a concentrated focus and study
on an individual or a single group over time to
determine the effects of an intervention. SSRDs
begin with the repeated measurement of a
dependent variable and systematically move
to the application and withdrawal of an indepen-
dent variable. The individual or single group
functions as the control for this experimental
research design.
SSRDs are also identified with a variety of
other names such as small-N designs, within
subject comparisons, single-case experimental
designs, and time series designs (Hadley &
Mitchell, 1995; Heppner et al., 2008). Time
series designs can also involve the study of only
one individual or a single through multiple
observations. Again, the dependent variable is
of interest as to whether it increases or decreases
in response to the independent variable. Some of
the threats to internal validity of time series
designs include instrumentation, testing, and
pretest treatment interaction (Sheperis & Miller,
2008). One of the more serious threats to a time
series design is history or maturation. Heppner
et al. (2008) suggested using a simple inter-
rupted time series design which allows for the
researcher to detect maturational changes that
can occur prior to initiation of treatment.
Another concern using time series design is an
appropriate length of time for collection of data
or the number of data points collected. Hadley
and Mitchell (1995) offered guidance regarding
time sampling keeping in mind the purpose of
the data collection. Their suggestions include
whole-interval time sampling (i.e., for increas-
ing behaviors), partial-interval time sampling
(i.e., to decrease behavior), and momentary time
sampling (i.e., occurrence of behavior only).
Although there may be questions and concerns
about using SSRDs or time series designs, they
are considered very useful in examining
relationships in settings such as counseling and
are practical for counselors to use in conducting
research with their clients. Moreover, these
designs have been cited as useful in program
evaluation as well.
SSRDs can take several forms including
A-B design, A-B-A design, A-B-A-B design,
B-A-B design, A-B-C-D design, and the multi-
ple baseline design. Although there are many
useful variations in SSRDs descriptions of three
32 Counseling Outcome Research and Evaluation 1(2)
classic designs and examples are provided: A-B,
A-B-A-B, and multiple baseline.
A-B Design
The initial phase of any SSRDs begins with
a baseline or pretreatment phase known as
Phase A. It is during this phase that repeated
measurement or observation gives the researcher
a quantifiable condition. The A phase can also be
thought of as the pretesting phase and also has
been coined simple phase change (Sheperis &
Miller, 2008). The B phase is designated as the
period of time when treatment or the intervention
is delivered along with continued measurement
or observation (see Figure 1). An examination
of the two phases ends this experiment. Infer-
ences are then drawn from a visual examination
of the graphed data and researchers look for
changes in trends or patterns (Lundervold &
Belwood, 2000; Sheperis & Miller, 2008).
However, Sharpley (2007) noted that researchers
may be restricted from using A-B design because
of the inability to concretely demonstrate the
effectiveness of an intervention. The most signif-
icant drawback in using the simple A-B design is
the lack of control for internal validity threats
such as extraneous variables. Extraneous vari-
ables such as holidays, crisis, illness, and so on
cannot be discounted in affecting the results,
thereby affecting internal validity. In order to
alleviate concerns over the internal validity,
researchers may implement a second A phase.
It is assumed that a return to the original baseline
will strengthen the inferences noted in the first
treatment phase, thereby creating a more robust
experiment (Sharpley, 2007).
One example of using an A-B design with a
client might involve thought-stopping interven-
tions. During the treatment Phase A, the coun-
selor and client would explore the frequency,
intensity, and duration of negative self-talk.

The client would be asked to chart their own
behavior, so there might be some discrepancies
in actual reporting. After a designated baseline
period of charting behaviors, the client and
counselor would examine the data and discuss
possibilities for intervention. This process
might take a few weeks during which the client
would continue to chart their negative self-talk.
After an agreed upon intervention, the client
would enter the treatment B phase and
implement the intervention. The client would
then begin to chart their progress using the
intervention. Again at the end of a determined
period, the client and counselor would examine
the data and evaluate the effectiveness of the
intervention. There could be other extraneous
variables that influence the effect of the inter-
vention, but the goal is to alleviate the client’s
distress.
A-B-A Design
The A-B-A design is an extension of the A-B
design which adds another baseline period. The
addition of another baseline creates a return to
baseline by removing the intervention also
known as the independent variable. It is
expected that the return to the second baseline
would result in a condition similar to the first
baseline, therefore allowing for a stronger infer-
ence regarding the effectiveness of the interven-
tion/interventions. Removal of an intervention
(which may have been successful) can result in
a deterioration of the client’s well-being in order
to return to the baseline. Although this design
strengthens the relationship of the variables, it
could result in deleterious effects for the client.
If the interventions are successful, the client
gains insight and hopefully generalization
of the intervention/interventions will occur in
other situations. Although a change occurs, the
counselor cannot be certain the intervention
alone caused the change, as there may be other
extraneous conditions influencing and affecting
the outcome. In order to fully demonstrate that
the counselor’s intervention was responsible,
replication would be accomplished through a
further extension of the A-B design. The design
would then become an A-B-A-B design. If the
intervention was not successful and a return
to baseline would not endanger the client, the
process can begin and the treatment phase may
consist of different interventions.
A-B-A-B Design
One method to resolve the internal validity
problem is the use of the A-B-A-B design also
known as a reversal design. This design is
simply a replication of the A-B design using
two baselines and two treatment phases. Using
the A-B-A-B design allows the researcher to
make a stronger statement regarding the inter-
nal validity and minimize extraneous variables.
The A-B-A-B design is an extension of the
A-B design wherein baseline and treatment
phases are repeated therefore it becomes a four
phase design. The initial baseline period is the
time of data gathering (A1) and a treatment
phase (B1). It then returns to a second baseline,
A phase is followed by another treatment
B phase (i.e., A2 and B2). The assumption
underlying the A-B-A-B design is that the
removal of the intervention in B1 will return the
subject to a level similar to the baseline A1 (Heppner et al., 2008). The idea is that a repli-
cation of intervention used in B1 will result
in reinforcement of the causal relationship
shown during the first A1 and B1 phases. This
greatly increases the ability of the counselor
(researcher) to infer the effectiveness of the
intervention.
The A-B-A-B design might be useful for a
child who has difficulty staying seated during
the school day. First, the counselor might act
as the observer and collect data to illustrate the
amount of time that the child is out of his or her
seat. During the course of counseling, questions
are asked to determine whether the out-of-seat
behavior serves a particular function. Several
reasons may be the root of the problem ranging
from avoidance of work that is too difficult, as
attention-seeking behavior, or because school-
work is not challenging. Understanding the
cause of the out-of-seat behavior is important
in order to develop the treatment plan. If the
clinician finds the child is feeling inadequate,
three treatment components might be used:
34 Counseling Outcome Research and Evaluation 1(2)
(a) modifying (i.e., decreasing) the complexity
of the work; (b) providing direct skill instruc-
tion, or (c) providing brief breaks contingent
upon completed work. A treatment plan would
be developed with the child, teacher, parents,
and counselors to determine what might be the
best intervention. If a token reinforcement is
used, it helps to make sure the reinforcement is
something desirable to the child. After complet-
ing the treatment plan, the Phase B treatment
would begin. Again observations and measure-
ment of the out-of-seat behaviors would begin.
In order to see whether changes occurred
because of the treatment, the intervention
would be removed with a return to the baseline
phase. If the treatment was responsible for
changes in behavior, the child’s behavior would
return to the level seen in the first baseline
period. This design would be implemented with
caution to ensure the child’s safety. The Phase A
baseline period would again be examined and a
second phase B treatment would begin.
Careful consideration must be given to using
this design because of the application and
withdrawal of interventions. The attempt of this
design is to provide evidence of the causal
effect of the independent variable. The assump-
tion of the clinician–researcher is that the
independent variable caused the change in the
dependent variable in Phase B1 and that
removal of the intervention would result in a
similar baseline period. If indeed the second
baseline phase closely resembled the first
baseline phase, this would strengthen the causal
relationship between the independent and
dependent variables and decrease the threats
to internal validity (Frankel & Wallen, 2009).
Ethical concerns are also addressed because the
problem of leaving the client without an inter-
vention is avoided.
Heppner et al. (2008) noted several limitations
of the A-B-A-B design: (a) a lack of reporting of a
statistical test (i.e., a quantitative value such as
a t test of F test); (b)carryover effects which
could be that the effects of the intervention are
irreversible and cannot be withdrawn; and (c)
potentially undesirable or unethical withdrawal
of an effective treatment. An alternative to the
A-B-A-B design is the multiple baseline design.
Multiple Baseline Designs
A multiple baseline design is basically a series
of A-B designs that are replicated in several
ways: (a) with the same individual across dif-
ferent behaviors known as multiple baseline
across behaviors; (b) with the same individual
across different settings known as multiple
baseline across settings; or (c) with the same
behavior across different individuals known
as multiple baseline across subjects. In the
multiple baseline across behaviors, there is a
baseline and treatment phase for two or more
different behaviors of the same subject. In a
multiple baseline across settings, there is
baseline and treatment phase for two or more
settings in which the same behavior of the
same subject is measured. Finally, the last
multiple baseline design known as multiple
baseline across subjects consists of a baseline
and treatment phase for the same behavior for
two or more subjects (Miltenberger, 1997).
Multiple baseline designs strengthen the
supposition that an intervention caused a beha-
vior change but still do not allow for statements
of causality (Polaha & Allen, 1999). This
may be one of the reasons for the lack of use
of multiple baseline designs by counselors.
Despite numerous examples of the use of mul-
tiple baseline designs cited by several authors,
multiple baseline design is not being used by
counseling professionals (Hadley & Mitchell,
1995; Heppner et al., 2008; Miltenberger,
1997). Heppner et al. (2008) found that the use
of multiple baseline research design is rarely
cited in counseling literature in contrast to
numerous citations found in clinical psychology
literature. Professional counselors may find this
design helpful especially for clients that are exhi-
biting a specific problematic behavior in more
than one setting such as in the home and at work.
Heppner et al. (2008) provided a good
example of a multiple baseline design. A coun-
selor may want to examine the effectiveness
of an intervention on family communication.
The counselor may determine two identifiable
behaviors such as (a) the amount of time after
dinner the husband and wife spend talking, and
(b) the amount of time after dinner the parents
Foster 35
spend talking with the children. During the
baseline A phase, the interaction time would be
measured for both of these. An intervention is
developed by the counselor and client to increase
communication between the spouses with the
assumption that the control would be communi-
cation between parents and children. The
intervention is implemented and the counselor
might expect that there would not be a difference
in the parent–child communication because no
intervention was implemented. Next step would
be to implement an intervention for parent–child
communication and the counselor would expect
that communication would increase. Other
targeted behaviors could also be addressed
over successive time periods to assess other
interventions.
Multiple baseline designs can be used with
individuals, couples, groups, or classrooms;
however, this type design is rarely seen in the
journals of counseling research. It is primarily
used in behaviorally oriented journals although
is gaining acceptance by the counseling profes-
sion. Acceptance by the counseling profession
may be due, in part, to the versatility of this
design with one individual across different
behaviors, settings, or for the same behavior
with several individuals. There are advantages
to using multiple baselines due to the generali-
zation of behaviors that may occur across
settings. The usefulness to counselors is the
ability to show clients their progress using a
visual reference. Another relevant and important
advantage for counselors is the ability to provide
outcome research and evidence of accountability
in managed care settings (Sheperis, Gardner,
Erford, & Shoffner, 2008; Sheperis & Miller,
2008).
SSRD Application Models
Sheperis and Miller (2008) used Data-based
Problem Solver (DBPS) model to help connect
clinical practice and research methods. DBPS
utilizes four phases: problem identification,
problem analysis, problem solution, and problem
evaluation. These four phases closely resemble
stages of the counseling process and can be used
as to think about the A-B design description as
well. The A phase or baseline is the period of time
in which no intervention or treatment is applied
and might be most commonly known to profes-
sional counselors as the rapport building stage.
As the counseling relationship is developed and
trust gained, the identification of the client’s
problem begins and research can provide
evidence of the effectiveness of treatment.
Another useful way to connect the counseling
process and research is to use the skilled-helper
model (Egan, 2007). First, in Egan’s model,
Stage 1 is ‘‘The Current Picture’’ of a client’s life
or situation (i.e., defining the problem). This
stage allows for relationship building between
counselor and client and begins the discovery
and clarification of problems, issues, and/or
concerns. This stage of discovery leads to the
assessment of the troublesome factors.
Data collection during this time investigates
the frequency, intensity, and/or duration of the
client’s problem. The client’s issue, concern, or
problem is categorized as the dependent
variable. The dependent variable can consist
of behaviors, emotional reactions, physiological
responses, personality traits, and thoughts.
Heppner et al. (2008) also suggested that
system characteristics (e.g., communication
patterns, cohesion, involvement) can also be the
dependent variable when researching groups,
families, or couples. It is during this period that
the professional counselor continues forming a
relationship and gathering information from the
client about their distress. Using the basic
sequence of who, what, where, when, how, and
why to help evaluate the client’s functioning
during the baseline Phase A period, the depen-
dent variable is measured (i.e., frequency, inten-
sity, or duration). Clients may even be unaware
of their level of their distress and measurement
can improve recognition of problematic beha-
viors (i.e., either overt or covert). A common
feature of SSRD is the repeated measurement
of the dependent variable over time. For
example, if a client engages in self-defeating
thoughts, the counselor might suggest measuring
the thoughts on a weekly, daily, or even hourly
basis to create the baseline. It should be noted that
the measurement during the Phase A relies on the
client’s self-report. It might be helpful for the
36 Counseling Outcome Research and Evaluation 1(2)
counselor to provide the client with a tally sheet
or some type form to complete during the Phase
A. Although self-report can be considered a
limitation in research, there are advantages.
Some of the advantages include ease of use, little
training required for the client, and SSRDs
are compatible with phenomenological views
(Heppner et al., 2008). On the other side, disad-
vantages to self-reporting can be the distortions
(either intentional or unintentional) by the client.
It is from this baseline that the counselor and
client examine the distress and move into the
working stage to create strategies or a treatment
plan to help the client.
Egan’s second stage is referred to as ‘‘The
Preferred Picture,’’ which allows the client to
explore options to create a better future (Egan,
2007). The working alliance between counselor
and client develops alternatives to alleviate the
client’s distress. It is during this stage of coun-
seling that counselor and client work together
to create realistic and challenging goals along
with moving into Stage 3 ‘‘The Way Forward’’
to develop strategies to accomplish goals
(Egan, 2007). This working stage develops into
the treatment B phase wherein interventions are
applied to the client’s situation. The counselor
continues to work with the client as the inter-
ventions are tried and plans for being successful
are reviewed. Assessment of the client’s func-
tioning occurs again during this phase to deter-
mine the effectiveness of the interventions. The
interventions are considered the independent
variable that can be manipulated or controlled.
An assessment of the intervention is then
compared to the baseline phase, allowing both
the client and the counselor to determine
whether the intervention was effective.
Discussion
The usefulness of SSRD as a tool for counselors
is multifaceted. First and foremost, the ease
with which SSRDs can be adapted into a
counselors’ practice is easily accomplished.
The low cost of data collection and the lack
of complicated statistics also create a user-
friendly tool for conducting outcome research.
As the era of accountability continues,
counselors can adopt SSRDs to create outcome
research needed to provide effectiveness of
counseling interventions. In order to encourage
more research in the counseling profession,
new ways of thinking about research must be
promoted. The counseling profession is still a
relatively new profession in relation to other
helping professions and as such strives to gain
recognition and provide evidence of the
effectiveness of counseling interventions, and
this can be accomplished through more empha-
sis on outcome research. Case studies were
early individualized research methods and
have evolved from uncontrolled methods to a
more scientific and controlled approach.
Since professional counselors generally focus
on individual clients it seems appropriate to
continue developing and implementing indivi-
dualized research evaluating the outcome of
our counseling practice (Heppner et al., 2008;
Sheperis et al., 2008).
A common goal of counseling outcome
research must be to help facilitate an under-
standing of human behavior. It is generally
accepted that SSRD is a useful tool for examin-
ing change within a single individual and is
ideal for describing individualist idiosyncrasies
(Heppner et al., 2008). Providing a visual
representation to the client will likely provide
evidence of the problematic behavior and
possibly provide reinforcement for the inter-
ventions (if successful). Visual representations
for both client and counselor are considered
more user-friendly and reinforce the clinical
significance of interventions (Sheperis & Miller,
2008). Alternatively, it can also provide useful
material for the counseling session by an investi-
gation of who, what, why, and how a specific
intervention did or did not work.
Early in counselor education programs,
outcome research must be promoted for several
reasons. First, accreditation of counselor educa-
tion training programs is one of the many steps
involved in creating a profession. In a classic
article by Klatt (1967), steps in the formation
of any profession include development of a
systematic body of knowledge, requiring
specific training. Council for Accreditation of
Counseling and Related Educational Programs
Foster 37
(CACREP) ensures that accredited counselor
education programs adhere to a systematic
curriculum, promoting standardized preparation
of future counselors (CACREP, 2009). Huber
and Savage (2009) suggest by promoting
research as a core value in graduate counselor
education programs, the identity of clinicians
as researchers would be strengthened. A final
point for consideration is the importance of
the ethical responsibility incumbent on the
counseling profession to provide interventions
and techniques that are effective, and the
documentation of our effectiveness can be
provided through research (American Counseling
Association [ACA], 2005).
Conclusion
SSRD has been called the best kept secret in
counseling (Lundervold & Bellwood, 2000).
Single-subject research can become an avenue
for counseling professionals in all settings, as
well as students and counselor educators to
evaluate their practice of counseling. In order
to promote the use of SSRD, counselor educa-
tion programs must be diligent in preparing
students to become producers of research
rather than consumers only. Likewise, counsel-
ing professionals must also answer the call to
provide the necessary outcome research pro-
viding evidence of counseling’s effectiveness.
Caveats include responsibility for adequate
training and attention to ethical considera-
tions; nevertheless SSRDs are easily incorpo-
rated into any counseling practice setting.
SSRD is only one of many research designs,
which can be used to enhance the counseling pro-
fession, our identity, our practice, and ultimately
and most importantly our client’s wellness.
