Terapia de Activación Conductual Transdiagnóstica en Grupo para la Depresión y la Ansiedad Coexistente en Adolescentes

Specific Aims and Hypotheses: This study will develop treatment materials for a transdiagnostic Group Behavioral Activation Therapy (GBAT). It will then conduct a double-gated screening of middle-school students (N=895) to identify youth with subclinical or clinical DSM-IV-TR anxiety or mood disorders. Eligible youth (N=35) will then participate in a randomized clinical trial of GBAT where 21 will be randomly assigned to GBAT and 14 to a 15-week waitlist period. This addresses critical needs to develop first-line early interventions that are evidence-based and can efficiently address commonly co-occurring problems in settings where treatment is needed most. Aim 1. To develop treatment materials and test GBAT's feasibility (e.g., recruitment and retention rates, therapist adherence) and acceptability to youth participants (client satisfaction, group cohesion, homework completion). Aim 2. To estimate initial efficacy of GBAT compared to a waitlist (WL) control in a randomized pilot study with 35 youth (21 assigned to two GBAT groups; 14 assigned to WL). It is hypothesized that GBAT will show greater pre- to post-treatment outcomes on primary (clinical diagnosis, symptom severity) and secondary measures (achievement of target goals, reduced avoidance, social and academic adjustment). Youth who receive GBAT will also show linear improvement on outcome measures from pretreatment through four-month follow-up. A second major goal of the project is to understand the functional role of avoidance in depression. Participating youth will carry Electronic Diaries (EDs; i.e., ipod touch) throughout the active treatment and follow-up phases and complete twice-daily reports of negative events, emotional and behavioral responses, and perceived function of one's responses. A non-clinical comparison group (n=18) will also carry EDs during a two-week period. Such Ecological Momentary Assessment (EMA) data has been used effectively with youth populations to determine the impact of positive and negative coping responses on depressive symptoms. Aim 3. The research suggests that depressed youth seek out depressogenic activities and respond less to positive events. Based on EMA data, the study hypothesizes that, compared to non-clinical comparisons: (a) depressed youth will identify more events as negative during the day, (b) depressed youth will respond with greater negativity than non-depressed youth, (c) the coping strategies used will be more avoidant or aimed at disengagement, and (d) the function of these strategies will be to minimize distress and conflict. Furthermore, youth who receive GBAT, compared to WL participants, will demonstrate increased ratio of engagement-based to avoidance-based coping strategies from pre- to post-treatment and 4-mo FU.
