ABSTRACT

Objective: To review the literature on the cognitive-behavioral treatment of children and adolescents with anxiety and

depressive disorders within the conceptual framework of evidence-based medicine. Method: The psychiatric and

psychological literature was systematically searched for controlled trials applying cognitive-behavioral treatment to

pediatric anxiety and depressive disorders. Results: For both anxiety and depression, substantial evidence supports the

efficacy of problem-specific cognitive-behavioral interventions. Comparisons with wait-list, inactive control, and active

control conditions suggest medium to large effects for symptom reduction in primary outcome domains. Conclusions:

From an evidence-based perspective, cognitive-behavioral therapy is currently the treatment of choice for anxiety and

depressive disorders in children and adolescents. Future research in this area will need to focus on comparing cognitive-

behavioral psychotherapy with other treatments, component analyses, and the application of exportable protocol-driven

treatments to divergent settings and patient populations. J. Am. Acad. Child Adolesc. Psychiatry, 2004;43(8):930–959.

Key Words: outcome studies, children and adolescents with major depression and dysthymic disorder, children and

adolescents with anxiety disorder, literature review.

Due in part to a productive interplay between researchand clinical practice (Rutter, 1999), many clinical re-searchers now believe that cognitive-behavioral therapy(CBT) administered within an evidence-based, multi-modal, multidisciplinary practice model is the psycho-therapeutic treatment of choice for youth withinternalizing disorders (Geddes et al., 1997; March andWells, 2003). In this context, the past 10 years wit-nessed the emergence of diverse, sophisticated, and em-pirically supported CBTs covering the range ofchildhood-onset anxiety and depressive disorders

(Bernstein and Shaw, 1997; Birmaher et al., 1996a,b).Using the tools of evidence-based medicine (EBM)(Sackett et al., 1997), this article provides a criticalreview of CBT for these conditions. We do not addressobsessive-compulsive disorder and posttraumatic stressdisorder, for which recent critical reviews are available(Cohen et al., 2000; Franklin et al., 2002; March,1995), or bipolar disorder, for which cognitive-behavioral interventions are just now emerging (Mc-Clellan and Werry, 1997). The reader interested in a“how-to-do-it” perspective may wish to pursue recentoverviews of CBT (Hibbs and Jensen, 1996; Reineckeet al., 2003) interventions for childhood-onset anxiety(Kendall et al., 1999, 2000, 2003; March and Mulle,1998; Rapee et al., 2000; Silverman and Kurtines,1996) and depressive disorders (Brent et al., 1997;Clarke et al., 1990).

dall and Panichelli-Mindel, 1995), a short overview isheuristically valuable. Historically, behavior therapy(the BT in CBT) evolved within the theoretical frame-work of classical and operant conditioning, with cog-nitive interventions (the C in CBT) assuming a moreprominent role with the increasing recognition thatperson–environment interactions are mediated by cog-nitive processes (Van Hasselt and Hersen, 1993).Looked at in the context of situational and/or cognitiveprocesses, BT is sometimes referred to as nonmedia-tional (emphasizing the direct influence of situationson behavior) and CT as mediational (emphasizing thatthoughts and feelings underlie behavior). Hence, be-havioral psychotherapists work with patients to changebehaviors and thereby to reduce distressing thoughtsand feelings. Cognitive therapists work to first changethoughts and feelings, with improvements in func-tional behavior following in turn.

Although CBT is often referred to as a unitary treat-ment, it is actually a diverse collection of complex andsubtle interventions that must each be mastered andunderstood from the social learning perspective. Sub-sequently, a cognitive-behavioral case formulationguides the therapist in administering treatment tech-niques in a flexible manner for the patient presentingwith any one disorder or comorbid presentation ofmental disorders (for an overview of a modular ap-proach to CBT interventions, see Curry and Reinecke[2003]). Nonetheless, despite their seeming differences,cognitive-behavioral interventions typically share fivequalities: (1) adherence to the scientist–clinicianmodel, whereby treatments are chosen based on dem-onstrated evidence or are applied within a case evalu-ation format to determine efficacy; (2) a thoroughidiographic assessment (e.g., functional analysis) of tar-get behaviors and the situational, cognitive, and behav-ioral factors that have established or are maintainingthe symptoms of interest (for a detailed overview ofhow to conduct a functional analysis, see Haynes andO’Brien [1990]); (3) an emphasis on psychoeducation;(4) problem-specific treatment interventions designedto ameliorate the symptoms of concern; and (5) relapseprevention and generalization training at the end oftreatment. For example, using cognitive restructuringand exposure-based interventions, CBT for anxiety dis-orders encourages cognitions and behaviors designed topromote habituation or extinction of inappropriatefears. Likewise, CBT for depression directly confronts

maladaptive depressogenic cognitions, including help-lessness, hopelessness, and hostility, and aims behavior-ally to reconstitute pleasant relationships, be theyintrapsychic, interpersonal, school, or spiritual. As evi-dence-based therapies, each is supported by a more orless robust research literature, and manuals are usuallyavailable to guide practitioners in using CBT for spe-cific problems. Thus, CBT fits nicely into the currentmedical practice environment that appropriately valuesempirically supported, brief, problem-focused treat-ments.

From this vantage point, CBT represents a develop-mentally sound approach to pediatric mental illness.Children normally acquire social-emotional (self andinterpersonal) competencies across time. The failure todo so, relative to age, gender, and culture-matchedpeers, may reflect capacity limitations, individualdifferences in the rate of skill acquisition for specificcompetencies, environmental factors, and/or the devel-opment of a mental illness. In CBT, the task of themental health practitioner is to understand the present-ing symptoms in the context of child-specific con-straints to normal development and to devise a tailoredtreatment program that eliminates those constraints sothat the youngster can resume a normal developmentaltrajectory insofar as is possible.

To the extent that symptom relief occurs, it can beassumed that improvement reflects concurrent changes(e.g., learning) in the CNS (Andreason, 1997; Hyman,2000). Thus, the cognitive-behavioral treatment of pe-diatric mental illness can be thought of as partiallyanalogous to the treatment of, for example, juvenile-onset diabetes, with the caveat that the target organ, thebrain in the case of major mental illness, requires in-terventions of much greater complexity. Althoughmedications are of importance—in diabetes, insulin,and in the anxiety or affective disorders, a serotoninreuptake inhibitor—the critical point is that each alsoinvolves crucial psychosocial interventions that work inpart by biasing the somatic substrate of the disordertoward more normal functioning (Hyman, 2000). Indiabetes, the behavioral intervention of choice is dietand exercise, and in the anxiety or affective disorders, itis cognitive-behavioral psychotherapy.

METHOD

EBM has emerged as a promising paradigm for medical practice(for a comprehensive review, see Sackett et al. [2000]) and is clini-

RESEARCH UPDATE REVIEW: CBT

J. AM. ACAD. CHILD ADOLESC. PSYCHIATRY, 43:8, AUGUST 2004 931

cally akin to the scientist–practitioner model in academic psychol-ogy (Barlow, 1993). EBM deemphasizes the more typical relianceon unsystematic clinical experience as a sufficient ground for clini-cal decision making. Instead, EBM stresses the examination of evi-dence from systematic diagnostic assessment technologies andclinical research as a tool to inform clinical practice, and it providesa heuristically valuable organizing focus for the individual clinicianseeking to transition efficacy and effectiveness studies into clinicalpractice at the level of the individual patient (Geddes et al., 1997).

Using established EBM criteria for assessing the validity of treat-ment studies as guides to clinical practice (Guyatt et al., 1993,1994, 1999), a search for relevant literature was conducted viaMedline and PsycINFO, using the following text terms: anxiety,depression, cognitive therapy, and behavior therapy. Only random-ized, controlled trials (RCTs) for individuals with a specific disorderwere included. Additionally, to be included, articles must have metthe following criteria: published in an English-language, peer-reviewed journal between 1990 and 2002; included children be-tween the ages of 8 and 18; included an outcome measure of knownclinical significance; and used an analytic strategy consistent withthe study design. A follow-up assessment was preferred but notrequired. Excluded from consideration were articles concerning thetreatment of obsessive-compulsive disorder, posttraumatic stressdisorder, or bipolar disorder; included were articles concerning thetreatment of specific phobias, social phobia, selective mutism, over-anxious disorder, separation anxiety disorder, panic disorder, gen-eralized anxiety disorder, major depression, and dysthymia.

The text of this article is supported by a series of tables thatsummarize the main findings of each study identified during theliterature search. The tables are organized by type of disorder (anxi-ety versus depression); within each disorder, separate tables sum-marize findings at post-treatment and at long-term follow-up.

The information presented in each table includes study citation(studies are listed in alphabetical order by first author), researchdesign (type, control condition, analysis sample), sample informa-tion (total number, age range, percentage of males, and ethnicity),the diagnoses targeted by the intervention, brief details about theintervention, primary dependent measures (both categorical andscalar), sample size in each treatment condition, proportion ofsample responding, magnitude of the treatment effect (portrayed interms of number needed to treat [NNT] and standardized effectsize estimates), and general comments by the authors.

The NNT is a measure of the average response, presented as theprobability of response in single patient units. Arithmetically, theNNT is the inverse of the absolute risk reduction (1/ARR), definedas the percentage of response in the experimental group minus thepercentage of response in the control condition. In practice, NNTrepresents the number of patients who need to be treated with theactive treatment to produce one additional positive outcome be-yond that obtainable with the control or comparison condition. Forexample, an NNT of 10 describes the number of patients whom aclinician would need to treat with the active treatment rather thanthe control treatment to see one additional positive outcome. A verysmall NNT (that is, an NNT that approaches 1) suggests that afavorable outcome occurs in nearly every patient who receives thetreatment and in relatively few patients in the comparison group.An NNT of 2 or 3 indicates that a treatment is quite effective.

Standardized effect size estimates were calculated with the assis-tance of ES (Shadish et al., 1999), a computer software programdesigned to calculate effect size estimates from published studies. EScalculates the standardized mean difference statistic, commonly re-ferred to as Cohen’s d and computed as d = (Mt − Mc)/SD, where

Mt is the mean of the treatment group, Mc is the mean of thecomparison group, and SD is the pooled within-group standarddeviation. All effect size estimates are reported such that positivescores indicate that the treatment group improved more than thecomparison group.

TREATMENT OF ANXIETY DISORDERS

To their advantage, cognitive-behavioral therapistshave a robust literature validating the effectiveness ofspecific psychological techniques for anxiety disordersand a steadily growing literature supporting the use ofprescriptive treatment protocols for these disorders.

Types of Investigations

Twenty-one RCTs evaluating a variety of cognitive-behavioral interventions for the treatment of child andadolescent anxiety disorders were identified (Table 1).As a group, these studies are noteworthy for their meth-odological rigor and the systematic way in which theyhave advanced the understanding of childhood anxietydisorders and how best to treat this important popula-tion. With respect to methodological rigor, all studiesused contrasting group designs in which active treat-ments were compared with either a wait-list or no-treatment control condition (Cornwall et al., 1996;Hayward et al., 2000; Kendall, 1994; Kendall et al.,1997; King et al., 1998; Shortt et al., 2001; Silvermanet al., 1999a) or an attention placebo-controlled con-dition (Beidel et al., 2000; Last et al., 1998; Muris etal., 2002). Moreover, several studies compared morethan one active treatment condition (Barrett, 1998;Barrett et al., 1996; Beidel et al., 2000; Cobham et al.,1998; Flannery-Schroeder and Kendall, 2000; Mend-lowitz et al., 1999; Menzies and Clarke, 1993; Muris etal., 2001; Nauta et al., 2003; Silverman et al., 1999b;Spence et al., 2000).

Investigators in this area have also systematicallyevaluated a variety of clinically relevant questions: forinstance, whether group CBT is more effective thanindividual CBT (Flannery-Schroeder and Kendall,2000; Manassis et al., 2002; Muris et al., 2001), wheth-er adding parental participation enhances treatmentoutcomes (Barrett, 1998; Barrett et al., 1996; Cobhamet al., 1998; Mendlowitz et al., 1999; Nauta et al.,2003; Shortt et al., 2001; Spence et al., 2000), whetherconcurrent treatment of parental anxiety enhancestreatment outcomes (Cobham et al., 1998), andwhether two active treatment components, which are

RESEARCH UPDATE REVIEW: CBT

J. AM. ACAD. CHILD ADOLESC. PSYCHIATRY, 43:8, AUGUST 2004 939

often combined in traditional cognitive-behavioral pro-tocols (e.g., behavioral contingency management versuscognitive self-control), are differentially effective (Sil-verman et al., 1999b). Moreover, several of the studiescited were replications and extensions of existing pro-tocols by independent researchers (Barrett, 1998; Bar-rett et al., 1996; Manassis et al., 2002; Mendlowitz etal., 1999; Muris et al., 2001, 2002).

Assessment Issues

Diagnosis and Symptom Profile. Valid and reliableassessment is essential to the skillful application andevaluation of cognitive-behavioral treatments (Thyer,1991) and is a strength of the cited studies taken as awhole. All but 2 of the 21 studies cited in Table 1(Cornwall et al., 1996; Menzies and Clarke, 1993) usedsemistructured clinical interviews to identify subjects ashaving an anxiety disorder as well as documenting di-agnostic comorbidities and assessing treatment out-comes. By a significant margin (13 of 21), the mostwidely used semistructured clinical interview was theAnxiety Disorders Interview Schedule, Child and Par-ents Versions (ADIS-C/P) (Silverman, 1987; Silver-man and Albano, 1996a,b; Silverman and Nelles,1988). This interview is most commonly administeredseparately to children and parents, and then data arecombined from both sources to derive a final “com-posite” diagnosis; however, several studies deviatedfrom this standard practice and relied solely on infor-mation obtained from parents to determine diagnosticstatus (Shortt et al., 2001; Spence et al., 2000) andtreatment outcome (Cobham et al., 1998; Flannery-Schroeder and Kendall, 2000; Kendall, 1994; Kendallet al., 1997; Shortt et al., 2001; Spence et al., 2000). Inaddition to providing a diagnosis, the ADIS requiresthe clinician to provide a clinician severity rating(CSR). The CSR is the clinician’s estimate of the de-gree of functional impairment and distress engenderedby the disorder (Albano and Silverman, 1996). Unfor-tunately, only two studies characterized the sample interms of the CSR (Hayward et al., 2000; Silverman etal., 1999a). Because the CSR may predict the natureand outcome of treatment, the failure of researchers toadequately characterize the baseline characteristics oftheir sample along this dimension is a notable defi-ciency.

Demographics and Severity. Both genders are largelyrepresented in the treated population, with only one

study containing a sample that was limited to females(Hayward et al., 2000). Although the majority of stud-ies attempted to recruit children and adolescents, theaverage age of subjects across all studies was approxi-mately 9.85 years. This leaves open the question ofgeneralizability of the research findings, as well as pro-tocol-driven interventions, to older adolescent popula-tions. Other demographic variables, such as ethnicityor socioeconomic status, were generally well docu-mented. However, with the exception of two trials (Sil-verman et al., 1999a,b), most studies had extremelylow rates of ethnic minority participation (see Pina etal. [2003] who examined the differential treatment re-sponse of Hispanic/Latino youth and European-American youth). A noted strength of the citedinvestigations was the clinical severity of the researchsample. All studies focused on subjects who soughtclinical services and whose impairment was severeenough to warrant a psychiatric diagnosis. No studyincluded children who were simply endorsing symp-toms of anxiety on a self-report measure.

Outcome Measures. To their credit, the majority ofcited investigations relied on a multimethod (e.g., clini-cal interview, self-report measures), multiinformant(e.g., child, parent, clinician) approach to documenttreatment outcomes. Both scalar and dichotomousmeasures that sampled specific symptom domains wereregularly reported. Another strength of many of thecited investigations was that outcomes were not re-stricted to the simple reporting of statistically signifi-cant symptom improvement or symptom change.More clinically informative outcomes were commonlyreported, such as clinically significant improvement(defined as changes that return deviant subjects towithin nondeviant limits [Kendall and Grove, 1988])and posttreatment diagnostic status (defined as the per-centage of children who no longer meet criteria for acurrent anxiety disorder). For instance, 14 of the 21investigations reported the posttreatment diagnosticstatus of subjects. However, the methods used to quan-tify diagnostic status varied moderately from study tostudy, which made it difficult to compare outcomesacross trials. For instance, some studies combined in-formation obtained from separate child and parentclinical interviews to determine posttreatment diagnos-tic status (Barrett, 1998; Barrett et al., 1996; Beidel etal., 2000; Last et al., 1998; Nauta et al., 2003; Silver-man et al., 1999a,b), whereas others relied solely on

COMPTON ET AL.

information obtained from the parent (Cobham et al.,1998; Flannery-Schroeder and Kendall, 2000; Kendall,1994; Kendall et al., 1997; Shortt et al., 2001; Spenceet al., 2000). Moreover, some studies defined a subjectas diagnosis free if criteria for his or her primary anxietydiagnosis were no longer met (Last et al., 1998),whereas others used a more restrictive definition anddefined a subject as diagnosis free if criteria for both hisor her primary and secondary (if present) anxiety di-agnoses were no longer met (e.g., Barrett, 1998).

Moderators of Outcome. Ten of the 21 cited investi-gations reported results of secondary analyses that at-tempted to determine whether basic demographic andclinical variables moderated treatment outcome (e.g.,age, sex, ethnicity, clinical severity, pretreatment diag-nosis, comorbidities). The most frequent finding is thatnone of the variables analyzed moderate treatment out-come (for a notable exception, see Barrett et al.[1996]). However, the strength of this conclusion mustbe tempered because few studies were sufficiently pow-ered to adequately address this important question.

Long-Term Follow-up. Although the follow-up pe-riod varied widely across the cited investigations (from3 months to 6 years, with a modal length of 12months), the general conclusion that can be reached isthat CBT for anxiety disorders in children and adoles-cents is a durable intervention (Table 2). With fewexceptions (Cobham et al., 1998), posttreatment gainswere largely maintained at follow-up and showed littledeterioration. Interestingly, several studies that foundsignificant differences between two active treatmentspost-treatment reported that, at follow-up, the twotreatments were equally effective. However, because allcited studies lacked an adequate control group duringthe follow-up period, competing explanations for thepositive results reported cannot be dismissed.

Treatments

The behavioral treatment of fear and anxiety in chil-dren builds on early studies indicating that anxiety isreadily conceptualized as a set of classically conditionedresponses that can be unlearned or counterconditionedthrough associative pairing with anxiety-incompatiblestimuli and responses. For example, in systematic de-sensitization (SD), anxiety-arousing stimuli are system-atically and gradually paired (imaginally or in vivo)with competing stimuli such as food, praise, imagery,or cues generated from muscular relaxation. SD with

children consists of three basic steps: (1) training inprogressive muscle relaxation, (2) rank ordering of fear-ful situations from lowest to highest, and (3) hierarchi-cal presentation of fear stimuli via imagery while thechild is in a relaxed state (Eisen and Kearney, 1995).SD appears to work well with older children and ado-lescents. Younger children, however, often have diffi-culty with both obtaining vivid imagery and acquiringthe incompatible muscular relaxation. Strategies suchas using developmentally appropriate imagery and ad-junctive use of workbooks may boost the effectivenessof these procedures with younger children.

Without encouragement, anxious children and ado-lescents often find it difficult to remain in the presenceof anxiety-arousing stimuli for a sufficient length oftime to allow habituation to occur in the natural en-vironment. In fact, in some cases, the process of nega-tive reinforcement maintains the anxiety response.That is, when an individual initially confronts an anxi-ety-provoking situation (e.g., the assignment of an oralreport for the socially anxious youth), there is an in-crease in discomforting sensations and anxiousthoughts (e.g., rapid heart rate, sweating, thoughts suchas “I’ll look stupid to others”). By escaping or avoidingthe situation, such as through complaints of feeling illand needing to leave class or the behavior of schoolavoidance/refusal, the individual feels immediate relieffrom the anxiety. This is the process of negative rein-forcement. The escape behavior is reinforced by therelief and sets the stage for cycles of anxiety arousalfollowed by escape or avoidance and relief.

After the adult treatment literature, the identifica-tion of the negative reinforcement paradigm led to thedevelopment of exposure-based interventions for awide range of pediatric anxiety disorders. Because es-cape and avoidance behaviors are negatively reinforcedby the cessation of anxiety, exposure-based proceduresrequire extended presentation of fear stimuli with con-current prevention of escape and avoidance behaviorsin order for the extinction of the conditioned responsesto occur. Unlike systematic desensitization, stimuluspresentation is not accompanied by progressive musclerelaxation. Rather, graduated imaginal and/or in vivoexposure to hierarchically presented fear stimuli is usedto attenuate anxiety to phobic stimuli. Gradual expo-sure, with the consent of the child, is generally consid-ered to produce less stress for the client (and therapist)and thus is often preferred over the use of more pre-

scriptive techniques, especially massed exposure orflooding.

Cognitive interventions, usually combined with ex-posure, also play a prominent role in CBT for anxiouschildren and adolescents. For example, Kendall andcolleagues developed a comprehensive cognitive-behavioral protocol for anxious youth that focuses ontransmitting coping skills to children in need (Kendall,1994; Kendall et al., 1997). Based on the premise thatanxious children view the world through a “template”of threat, automatic questioning (e.g., “What if . . .”),and behavioral avoidance, treatment is focused on pro-viding educational experiences to build a new “copingtemplate” for the child. Therapists assist the children toreconceptualize anxiety-provoking situations as prob-lems to be solved and situations with which to cope. Avariety of cognitive-behavioral components assist thetherapist and child in building the coping template:relaxation training, imagery, correcting maladaptiveself-talk, problem-solving skills, and managing rein-forcers. Therapists use coping modeling, role-play re-hearsals, in vivo exposure, and a collaborativetherapeutic relationship with the child to facilitate thetreatment progress. As a rule, parents are actively in-volved in all facets of treatment as collaborators in thechange process.

For example, when significant others are trapped inthe child’s anxiety symptoms, it is crucial that they stopparticipating in or reinforcing the child’s avoidancestrategies or rituals. To test the hypothesis that addinga family anxiety management component would boosttreatment effectiveness, Barrett et al. (1996) developeda parallel family program to Kendall’s “Coping Cat”based on behavioral family intervention strategiesfound effective for the treatment of externalizing dis-orders in youth. After the completion of each childsession with the therapist, the child and parents wouldparticipate in a family anxiety management sessionwith the therapist. The crux of the program is to em-power parents and children by forming an “expertteam” to overcome and master anxiety. Parents aretrained in reinforcement strategies, with an emphasison differential reinforcement and systematic ignoringof excessive complaining and anxious behavior. How-ever, unilateral extinction strategies, such as when aparent returns the school-phobic child to school byforce, have significant disadvantages relative to consen-sual child involvement: (1) lack of a workable strategy

RESEARCH UPDATE REVIEW: CBT

J. AM. ACAD. CHILD ADOLESC. PSYCHIATRY, 43:8, AUGUST 2004 947

for managing the child’s distress, (2) disruption of thetreatment relationship, (3) inability to target symptomsthat are out-of-sight for parents and teachers, and (4),most important, failure to help the child internalize amore skillful strategy for coping with current and po-tential future anxiety symptomatology.

MAJOR DEPRESSION

At any one time, approximately 1 in 20 children andadolescents suffers from major depressive disorder, withrates of depression rising dramatically in adolescents,especially in girls. Although the economic burden ofdepression in youth is uncertain, the human burden isconsiderable, especially with teenage suicide. Hence, itis of critical importance to note that the empirical lit-erature is more supportive for problem-specific psycho-therapies, especially CBT, than for medicationmanagement of pediatric depressive disorders (Birma-her et al., 1996a; Hoberman et al., 1996). In particular,several controlled trials have demonstrated that indi-vidual or group administered cognitive-behavioral psy-chotherapy is an effective treatment for depressedyouth (Brent et al., 1997; Lewinsohn et al., 1994), andsome investigators now consider CBT to be the treat-ment of choice for this disorder (Reinecke et al., 1998).

Types of Investigations

Twelve articles describing a variety of cognitive-behavioral intervention packages for the treatment ofchild and adolescent depression were identified (Table3). Although these depression trials are equally meth-odologically rigorous when compared with child andadolescent anxiety trials (e.g., contrasting group designscomparing one or more active treatments with eitherno treatment, wait-list, or attention placebo controls),the number of studies is significantly fewer, and theresearch agenda to date has been less coherent andsystematic. Moreover, several of the studies with nullfindings likely had insufficient power to detect a be-tween-group treatment effect due to the small samplesize of each treatment condition. This is a notable de-ficiency and contributes to the widely held notionamong practitioners that all treatments for depressionare equally effective. It also makes it difficult, if notimpossible, to reach strong conclusions regarding thedifferential efficacy of the treatments evaluated.

Two studies addressed the question of whether add-ing a separate treatment module for parents incremen-

tally improves outcomes (Clarke et al., 1999;Lewinsohn et al., 1990). One study compared indi-vidual CBT to systemic behavioral family therapy(Brent et al., 1997). Another study evaluated the rel-evant question of whether adding CBT to usual care ina health maintenance organization is better than usualcare alone (Clarke et al., 2002). Five studies evaluatedthe efficacy of one or more CBT interventions in de-signs that included either an attention placebo condi-tion (Kahn et al., 1990; Liddle and Spence, 1990;Vostanis et al., 1996; Wood et al., 1996) or a no-treatment control (Weisz et al., 1997). One studycompared individual CBT with interpersonal psycho-therapy (Rossello and Bernal, 1999). One investigationevaluated the effects of maintenance CBT for depressedadolescents (Clarke et al., 1999). One study evaluatedthe acceptability and efficacy of a combined cognitive-behavioral family education treatment (Asarnow et al.,2002). Finally, one study evaluated the efficacy of cog-nitive bibliotherapy for adolescents with mild to mod-erate depressive symptoms (Ackerson et al., 1998). Nopublished investigations compared components oftreatments, and there were no systematic replicationstudies by independent investigators.

Assessment Issues

Diagnosis and Symptom Profile. Six of the 12 studiesused semistructured clinical interviews to identify sub-jects as having DSM major depressive disorder or dys-thymia (Brent et al., 1997; Clarke et al., 1999, 2002;Lewinsohn et al., 1990; Vostanis et al., 1996; Wood etal., 1996). The most commonly used interview was theSchedule for Affective Disorders and Schizophrenia forSchool-Age Children (Chambers et al., 1985; Orvas-chel and Puig-Antich, 1986; Puig-Antich and Cham-bers, 1978). The remaining six studies either failed tomention the specific assessment procedures used to de-termine inclusion criteria (Rossello and Bernal, 1999)or enrolled subjects solely on the basis of mild to mod-erate levels of self-reported depressive symptomatology(Ackerson et al., 1998; Asarnow et al., 2002; Kahn etal., 1990; Liddle and Spence, 1990; Weisz et al., 1997).The same six investigations that used semistructuredclinical interviews also assessed comorbidity but failedto analyze whether comorbidity status was related totreatment outcome. Thus, failure to systematically as-sess the impact of comorbidity on outcome is a criticaldeficiency in both the anxiety and depression literature.

RESEARCH UPDATE REVIEW: CBT

J. AM. ACAD. CHILD ADOLESC. PSYCHIATRY, 43:8, AUGUST 2004 951

Demographics. Although both males and females arerepresented in the treated populations, other basic de-mographic variables, such as ethnicity, were generallynot well documented. Only 7 of the 12 cited investi-gations provided the ethnic breakdown of the sample.Moreover, the majority of children who have partici-pated in research studies to date have been overwhelm-ingly white, suggesting that future studies will beneeded to evaluate the exportability of protocol-drivenCBT treatment packages to divergent patient popula-tions.

Outcome Measures. All the cited investigations reliedon psychometrically sound measures to documenttreatment results and changes in specific symptom do-mains. One-half of the studies reported the percentageof subjects who no longer met criteria for a depressivedisorder after treatment (Brent et al., 1997; Clarke etal., 1999, 2002; Lewinsohn et al., 1990; Vostanis et al.,1996; Wood et al., 1996), and several studies reportedthe percentage of subjects who returned to the nonde-viant ranges on the primary outcome measures. Onlythree investigations provided quantitative measures ofchange in functional status (Brent et al., 1997; Clarkeet al., 1999, 2002). Because little is currently knownabout how treatments affect academic, social, and fam-ily domains, future studies would benefit from includ-ing a more diverse range of outcomes (Compton et al.,2002).

Long-Term Follow-up. The data addressing the du-rability of CBT for adolescent depression are mixed(Table 4). In general, studies characterized by a rela-tively short follow-up period (from 1 to 9 months)report that posttreatment gains are largely maintained,with several studies showing continued improvement.However, studies with longer follow-up periods (from9 months to 2 years) and low attrition rates at follow-up found that a sizable percentage of subjects contin-ued to report significant depressive symptoms or arecurrence of their depressive illness (Birmaher et al.,2000; Vostanis et al., 1996, 1998; Wood et al., 1996).Factors found to predict a lack of recovery or relapseinclude low self-esteem (Vostanis et al., 1996, 1998),comorbidity at post-treatment (Vostanis et al., 1998),severity of depression or high level of functional im-pairment at baseline (Birmaher et al., 2000), the pres-ence of subsyndromal depression (Brent et al., 2001),parental depression (Brent et al., 1998; Clarke et al.,2002), parent–child conflict (Birmaher et al., 2000),

and the source of treatment referral (Birmaher et al.,2000). These studies suggest that depression in adoles-cence is associated with a high risk of recurrence. Theyalso underscore the importance of developing interven-tions that specifically target adolescents at risk of re-lapse and investigate the impact of continuationtreatment on long-term outcomes.

Treatments

Like other cognitive-behavioral treatment packages,CBT for depression in youths is a present-oriented,skills-based treatment that, in this case, is based on theassumption that depression is either caused or main-tained by the way one perceives situations and events(e.g., cognitions about the world and self) and the pres-ence of skill deficits (both emotional and behavioral)that prevent the patient from interacting effectivelywith the world. Because personality is an interactivemultidirectional system of cognitions, behaviors, andemotions, depression is manifested in each of the threecomponents of the personality. However, CBT for de-pression assumes that symptom change is most likely tooccur through interventions that modify patterns ofbehavior through skills acquisition and patterns of cog-nition, with changes in depressed mood following inturn. Among the behavioral and cognitive skill deficitsthat may characterize a depressed youth are low levelsof involvement in pleasant activities, poor problem-solving and assertion skills, cognitive distortions thatnegatively bias perceptions, negative automaticthoughts, negative views of self and future, and failureto attribute positive outcomes to internal, stable, orglobal causes. The role of the therapist, therefore, is toestablish a collaborative working relationship with theadolescent and to help the adolescent learn new ways ofbehaving and thinking, which in turn reduces depres-sive severity and risk of relapse.

Current cognitive-behavioral treatment packagesfor depressed youths share two salient characteristics:(1) general and “required” skill building sessions andoptional “modular” sessions for specific problems and(2) the integration of parent and family sessions withindividual CBT (Treatment for Adolescents with De-pression Study, 2003). Treatment is generally designedto improve the teenager’s problem-solving abilitywhen faced with a stressful situation, for example,parent–child conflict, role transitions, grief reactions,or peer problems. Therefore, the required aspects of

treatment include psychoeducation about depressionand its causes, goal setting with the adolescent, andgeneral problem-solving skills. Modules, chosen jointlyby the therapist and adolescent, then address thespecific skill deficits of the teenager. Because parent–child conflict is both a risk factor for depression andpredictive of poor treatment outcome and relapse, in-cluding a parent component in CBT is justified on anad hoc basis. Moreover, evidence is beginning toemerge that combined child and parent treatment maybe more effective than treatment directed at the teen-ager alone (Lewinsohn et al., 1990). In addition toteaching contingency management procedures, parentsare provided with alternative, effective methods for par-enting and creating a more positive family environ-ment. Furthermore, family interactions are targeteddirectly to shape and reinforce effective communica-tion and to increase pleasant activities and positive af-fect.

DISCUSSION

A substantial evidence base supports the efficacy ofproblem-specific cognitive-behavioral interventions fora variety of childhood and adolescent anxiety and de-pressive disorders. Unlike other psychotherapeutictechniques that have been applied to these disorders,CBT is consistent with an EBM perspective that valuesempirically supported problem-focused treatments.CBT presents a logical theoretical framework to guidepractitioners through an idiographic assessment of spe-cific problem domains, the delivery of problem-specifictreatment interventions, and well-specified outcomesto monitor treatment progress. However, CBT is notsimplistic. Helping children, adolescents, and parentsmake rapid and difficult behavior change over shorttime intervals requires considerable expertise and train-ing.

Future research in the areas of childhood and ado-lescent anxiety and depressive disorders will need tofocus on the following areas. First, controlled trialscomparing medications, CBT, and their combinationare needed to determine whether combined treatmentprovides an additive benefit in terms symptom reduc-tion. Second, treatment-dismantling studies are neededto identify the relative contributions of specific CBTcomponents to symptom reduction and treatment ac-ceptability. Third, mediational analyses (how a treat-

ment works) are needed to refine treatmentinterventions and better understand the mechanism(s)through which treatments achieve their therapeutic ef-fect. Fourth, follow-up studies with adequate controlgroups will be necessary to evaluate the long-term ben-efit of CBT, including examining whether boosterCBT sessions reduce relapse rates and whether inter-vening in childhood prevents the onset of adult psy-chiatric disorders. Finally, studies with diverse patientpopulations are needed to evaluate the exportabilityand generalizability of currently available protocol-driven treatments.
