The Origins and Current Status of Behavioral Activation Treatments for Depression

Sona Dimidjian; Manuel Barrera; Christopher R. Martell; Ricardo F. Muñoz; Peter M. Lewinsohn

The past decade has witnessed a resurgence of interest in behavioral interventions for depression. This contemporary work is grounded in the work of Lewinsohn and colleagues, which laid a foundation for future clinical practice and science. This review thus summarizes the origins of a behavioral model of depression and the behavioral activation (BA) approach to the treatment and prevention of depression. We highlight the formative initial work by Lewinsohn and colleagues, the evolution of this work, and related contemporary research initiatives, such as that led by Jacobson and colleagues. We examine the diverse ways in which BA has been investigated over time and its emerging application to a broad range of populations and problems. We close with reflections on important directions for future inquiry.

Extreme nonresponse in cognitive therapy: can behavioral activation succeed where cognitive therapy fails?

Sandra J. Coffman; Christopher R. Martell; Sona Dimidjian; Robert Gallop; Steven D. Hollon

In a recent placebo-controlled comparison, behavioral activation was superior to cognitive therapy in the treatment of moderate to severely depressed adults. Moreover, a subset of patients exhibited a pattern of extreme nonresponse to cognitive therapy on self-reports of depression not evident on the clinician ratings. These patients were severely depressed, functionally impaired, and had primary support group problems; most also described themselves as having life-long depressions. Comparable numbers of patients with such characteristics were assigned to behavioral activation, indicating that randomization did not fail, and most instances occurred in the context of adequate cognitive therapy. If this pattern of self-reported extreme nonresponse to cognitive therapy replicates, it would suggest that there might be a subset of patients who see themselves as doing better with sustained attention to behavior change in time-limited treatment.

BackgroundDespite their potential as low-threshold, low-cost and high-flexibility treatments of depression, behavioural activation and physical exercise have not yet been directly compared. This study will examine the effects of these interventions, administered via the Internet. The added effect of providing a treatment rationale will also be studied, as well as a relapse prevention program featuring cognitive behavioural therapy components.Methods/DesignThis randomised controlled trial will include 500 participants meeting the diagnostic criteria for major depression, recruited in multiple cycles and randomised to either a waiting list control group with delayed treatment, or one of the four treatment groups: (1) physical exercise without a clear treatment rationale; (2) physical exercise with treatment rationale; (3) behavioural activation with treatment rationale; or (4) behavioural activation without a clear treatment rationale. Post treatment, half of the participants will be offered a relapse prevention program. Primary outcome measure will be the Patient Health Questionnaire 9-item. Secondary measures include diagnostic criteria for depression, as well as self-reported anxiety, physical activity and quality of life. Measurements - done via telephone and the Internet - will be collected pre-treatment, weekly during treatment period, immediately post treatment and then monthly during a 24-month follow-up period.DiscussionThe results of this study will constitute an important contribution to the body of knowledge of the respective interventions. Limitations are discussed.Trial registrationClinicalTrials.gov: NCT01619930

BackgroundCognitive behaviour therapy (CBT) is an effective treatment for depression. However, CBT is a complex therapy that requires highly trained and qualified practitioners, and its scalability is therefore limited by the costs of training and employing sufficient therapists to meet demand. Behavioural activation (BA) is a psychological treatment for depression that may be an effective alternative to CBT and, because it is simpler, might also be delivered by less highly trained and specialised mental health workers.Methods/DesignCOBRA is a two-arm, non-inferiority, patient-level randomised controlled trial, including clinical, economic, and process evaluations comparing CBT delivered by highly trained professional therapists to BA delivered by junior professional or para-professional mental health workers to establish whether the clinical effectiveness of BA is non-inferior to CBT and if BA is cost effective compared to CBT. Four hundred and forty patients with major depressive disorder will be recruited through screening in primary care. We will analyse for non-inferiority in per-protocol and intention-to-treat populations. Our primary outcome will be severity of depression symptoms (Patient Health Questionnaire-9) at 12 months follow-up. Secondary outcomes will be clinically significant change and severity of depression at 18 months, and anxiety (General Anxiety Disorder-7 questionnaire) and health-related quality of life (Short-Form Health Survey-36) at 12 and 18 months. Our economic evaluation will take the United Kingdom National Health Service/Personal Social Services perspective to include costs of the interventions, health and social care services used, plus productivity losses. Cost-effectiveness will explored in terms of quality-adjusted life years using the EuroQol-5D measure of health-related quality of life.DiscussionThe clinical and economic outcomes of this trial will provide the evidence to help policy makers, clinicians and guideline developers decide on the merits of including BA as a first-line treatment of depression.Trial registrationCurrent Controlled Trials ISRCTN27473954

This study aimed to examine implementation feasibility and initial treatment outcomes of a behavioral activation (BA) based treatment for adolescent depression, the Adolescent Behavioral Activation Program (A-BAP). A randomized, controlled trial was conducted with 60 clinically referred adolescents with a depressive disorder who were randomized to receive either 14 sessions of A-BAP or uncontrolled evidenced-based practice for depression. The urban sample was 64% female, predominantly Non-Hispanic White (67%), and had an average age of 14.9 years. Measures of depression, global functioning, activation, and avoidance were obtained through clinical interviews and/or through parent and adolescent self-report at preintervention and end of intervention. Intent-to-treat linear mixed effects modeling and logistic regression analysis revealed that both conditions produced statistically significant improvement from pretreatment to end of treatment in depression, global functioning, and activation and avoidance. There were no significant differences across treatment conditions. These findings provide the first step in establishing the efficacy of BA as a treatment for adolescent depression and support the need for ongoing research on BA as a way to enhance the strategies available for treatment of depression in this population.

BACKGROUND A major problem today is that only about fifty percent of those affected by depression seeks help. One way to reach more sufferers would be by offering easily accessible internet based treatments. The purpose of this study was to compare/evaluate four therapist supported internet administered treatments. METHOD/RESULTS Two hundred eighty six participants were included. The treatment period lasted twelve weeks, consisting of the following treatments: 1) physical activity without treatment rational, 2) physical activity with treatment rational, 3) behavioral activation without treatment rational and 4) behavioral activation with treatment rational. All groups (including a control-group) showed a significant decrease in depressive symptoms. When the treatment groups were pooled and compared to the control group, there were significant differences from pretest to posttest (Hedges gav treatment =1.01, control group =0.47). This held true also when each of the four treatment groups was compared to the control group, with one exception: Physical activity without treatment rationale. LIMITATIONS The differences between how many modules the participants completed could indicate that there are other factors than the treatments that caused the symptom reduction, however, the dose-response analysis did not detect any significant differences on account of modules completed. CONCLUSIONS The results support the positive effects of internet administered treatments for depression, and highlights the importance of psychoeducation, which tends to affect both the treatment outcome and the probability of remaining in treatment. These aspects need to be considered when developing and conducting new treatments for depression, since they would increase the likelihood of positive treatment outcomes.

Clinical validation of a non-heteronormative version of the Social Interaction Anxiety Scale (SIAS)

Philip Lindner; Christopher R. Martell; Jan Bergström; Gerhard Andersson; Per Carlbring

IntroductionDespite welcomed changes in societal attitudes and practices towards sexual minorities, instances of heteronormativity can still be found within healthcare and research. The Social Interaction Anxiety Scale (SIAS) is a valid and reliable self-rating scale of social anxiety, which includes one item (number 14) with an explicit heteronormative assumption about the respondent´s sexual orientation. This heteronormative phrasing may confuse, insult or alienate sexual minority respondents. A clinically validated version of the SIAS featuring a non-heteronormative phrasing of item 14 is thus needed.Methods129 participants with diagnosed social anxiety disorder, enrolled in an Internet-based intervention trial, were randomly assigned to responding to the SIAS featuring either the original or a novel non-heteronormative phrasing of item 14, and then answered the other item version. Within-subject, correlation between item versions was calculated and the two scores were statistically compared. The two items’ correlations with the other SIAS items and other psychiatric rating scales were also statistically compared.ResultsItem versions were highly correlated and scores did not differ statistically. The two items’ correlations with other measures did not differ statistically either.ConclusionsThe SIAS can be revised with a non-heteronormative formulation of item 14 with psychometric equivalence on item and scale level. Implications for other psychiatric instruments with heteronormative phrasings are discussed.

Using Acceptance in Integrative Behavioral Couple Therapy

Christopher R. Martell; David Atkins

Publisher Summary This chapter focuses on acceptance techniques as they pertain to integrative behavioral couple therapy (IBCT), which focuses on helping couples give up their agenda to change one another and interact in such a way to build greater intimacy through acceptance. IBCT therapists use standard assessment measures such as the dyadic adjustment scale (DAS) and the marital satisfaction inventory (MSI). When working with same-sex couples, the MSI is less desirable because it has forms for ‘‘husband’’ and ‘‘wife,’’ but the DAS is gender neutral. The conflict tactics scale (CTS) is a good assessment tool for domestic violence. A final tool, currently under development, is the frequency and acceptability of partner behavior scale (FAPB), which measures areas of concern to each partner, and how acceptable (or not) the behavior is to the partner, as well as frequency of occurrence. The assessment phase covers four sessions, where the couple is interviewed together, each partner is interviewed individually, and the therapist provides feedback and a case formulation to the couple. IBCT therapists may use techniques such as behavior exchange that utilize arbitrary reinforcement in the form of assigning partners to do nice things for one another, such techniques are used sparingly.
