    Esta investigación buscó adaptar a formato grupal el protocolo Breve de Activación Conductual para Depresión - BATD-R (Lejuez et al., 2011), y evaluar su efecto sobre las conductas depresivas y saludables en un grupo de universitarios con síntomas depresivos mediante un diseño de caso único AB con seguimiento. Se obtuvo excelente consistencia en las calificaciones realizadas por tres evaluadores del BATD-G (Kfree= .85; 95% IC= [.65, 1.00]). Posteriormente, se probó su efecto en siete estudiantes universitarios mayores de edad con sintomatología depresiva leve y moderada. El análisis visual y pruebas tau-U mostraron efectos significativos sobre las frecuencias de las conductas depresivas (tau-U = -.58, p=.00) y saludables (tau-U= .92, p=.00), al comparar la fase A con el seguimiento. Las comparaciones de las puntuaciones de las escalas aplicadas evidenciaron la disminución de la sintomatología depresiva (Zung SDS) en las medidas antes y después del tratamiento, y un incremento significativo en la Percepción de Refuerzo Medioambiental (EROS) en 5 de los 7 participantes. El BATD-G se constituye en un protocolo prometedor para tratar la sintomatología depresiva por las ventajas de la administración de una terapia grupal.

    This research was aimed to adapt the Brief Behavioral Activation Treatment for Depression (BATD-R) (Lejuez et al., 2011) to a group format, and evaluate its effect on healthy and depressive behaviors of a group of college students with depressive symptoms using an experimental single-case AB design with follow-up. Three judges with experience and training in AC management assessed the level of adaptation of the treatment session by session with a Likert scale from 1 to 5. An excellent consistence in its quantitative assessments (Kfree = .85; 95% IC= [.65, 1.00]) and high agreement (87.9%) was found. Means under 5 in each session were taken as an indicator of revision and adjusting. In eight out of the eleven assessed sessions, means equal to the maximum assessment (M=5.0) were reached. In the preliminary session (M=4.0; D.E.=0), a space to foster motivation and specify the structure of the treatment was implemented. In sessions 1 (M=4.7; D.E.=0.6) and 3 (M=4.7; D.E.=0.6) minimal adjustments were made. To assess the effect of the treatment, 100 college students with subclinical depression according to the Zung SDS scale (35 or over) were chosen; nine gave their consent and two drop out the process. After the whole application with seven participants, its effect on depressive symptomatology from mild to moderate was tested. The visual analysis, tau-U tests as well as pre and post treatment comparisons of the scales demonstrated significant effects on the frequencies of healthy (tau-U = .92, p=.00) and depressive (tau-U = -.58, p=.00) behaviors in the comparison A-monitoring. A decrease of the depressive symptomatology measured by the Zung SDS scale was observed when comparing the pre (M=43.4; D.E.=5.8) and post (M=40.3; D.E.=8.4) treatment measures and monitoring (M=35; D.E.=5.6). All participants had a decrease in the score of the Zung SDS test with severe changes according to the cut points suggested in three of them. Regarding the Environmental Reward Observation Scale (EROS), a progressive increase in the score of the pre (M=25.0; D.E.=3.5) and post (M=29.7; D.E.=3.9) treatment and monitoring (M=32.6; D.E.=3.9) was evidenced. Five out of the seven participants obtained measures over RCCrit, which shows a significant increase, from a clinical point of view, in the score of the EROS. The BATD-G could be a promising treatment to treat the depressive symptomatology since it would provide a higher efficiency due to the advantages of group therapy.
