La investigación hasta la fecha ha prestado poca atención a la regulación del afecto positivo en la adolescencia. Nuestros objetivos fueron construir un cuestionario para evaluar las respuestas al afecto positivo en adolescentes y estudiar las relaciones que presentan con el ajuste psicológico. Una muestra de 1.810 adolescentes completó el cuestionario de respuestas al afecto positivo (con tres dimensiones: rumiación positiva centrada en la emoción, rumiación positiva centrada en uno mismo e inhibición) y tres autoinformes de ajuste psicológico (satisfacción vital, autoestima y síntomas depresivos). El cuestionario mostró buena fiabilidad por consistencia interna y la misma estructura factorial que estudios previos con adultos. Un modelo de ecuaciones estructurales indicó que las respuestas de rumiación positiva centrada en la emoción y en uno mismo se relacionaron positivamente con la satisfacción vital y la autoestima, y negativamente con los síntomas depresivos, mientras que la inhibición del afecto positivo presentó asociaciones opuestas.

This study tested the plausibility of a theoretical model of change for the Penn Resiliency Program (PRP), a cognitive-behavioral (CB) depression prevention program for adolescents. Middle school students (N = 697) were randomized to PRP, an assessment-only control condition (CON), or a placebo-control condition (PLA). Explanatory style and depressive symptoms were evaluated over 24 months of follow-up. Relative to both CON and PLA, there were significant indirect effects of PRP on 12-month levels of depressive symptoms through improvements in explanatory style in two of three participating schools. Within a third school, where PRP was not effective in targeting depressive symptoms (Gillham et al. in J Consult Clin Psychol 75(1):9–19, 2007), there was no evidence of group differences in growth in explanatory style or indirect effects. When effective, PRP’s CB training provides incremental value over non-specific components and there are indirect effects on depressive symptoms through improvements in explanatory style.

This study aimed to analyze the prospective associations during adolescence between depressive symptoms and response styles to positive affect and to examine gender differences. A longitudinal study was conducted with three waves separated by 1 year each to assess a non‐clinical sample of 622 Spanish adolescents who were 13 and 14 years old (50.2% boys, 49.8% girls). The participants completed self‐report measures of depressive symptoms and responses to positive affect (emotion‐focused positive rumination, self‐focused positive rumination and dampening of positive emotion). The results showed that the increase in depressive symptoms was associated with an increase in dampening and decreases in emotion‐focused and self‐focused positive rumination. Furthermore, girls presented more depressive symptoms, as well as higher dampening and lower self‐focused positive rumination, than boys. The conclusions highlight the need to consider responses to positive affect in explaining gender differences in depressive symptoms during mid‐adolescence, as well as in designing prevention programs.

Adolescence represents a vulnerable developmental period for depression and an opportune time for prevention efforts. In this study, 186 adolescents with elevated depressive symptoms (M age = 14.01, SD = 1.22; 66.7% female; 32.2% racial minority) were randomized to receive either Interpersonal Psychotherapy–Adolescent Skills Training (IPT-AST; n = 95) delivered by research clinicians or group counseling (GC; n = 91) delivered by school counselors. We previously reported the short-term outcomes of this school-based randomized controlled trial: IPT-AST youth experienced significantly greater improvements in depressive symptoms and overall functioning through 6-month follow-up. Here, we present the long-term outcomes through 24 months postintervention. We examined differences in rates of change in depressive symptoms and overall functioning and differences in rates of depression diagnoses. Youth in both conditions showed significant improvements in depressive symptoms and overall functioning from baseline to 24-month follow-up, demonstrating the efficacy of school-based depression prevention programs. However, the two groups did not differ in overall rates of change or in rates of depression diagnoses from baseline to 24-month follow-up. Although IPT-AST demonstrated advantages over GC in the short term, these effects dissipated over long-term follow-up. Specifically, from 6- to 24-month follow-up, GC youth showed continued decreases in depressive symptoms, whereas IPT-AST youth showed a nonsignificant increase in symptoms. GC youth remained relatively stable in overall functioning, whereas IPT-AST youth experienced a small but statistically significant worsening in functioning. This study highlights the potential of school-based depression prevention efforts and the need for further research.

This study examined how social support seeking and rumination interacted to predict depression and anxiety symptoms 6 months later in early adolescents (N = 118; 11-14 years at baseline). We expected social support seeking would be more helpful for adolescents engaging in low rather than high levels of rumination. Adolescents self-reported on all measures at baseline, and on depression and anxiety symptoms 6 months later. Social support seeking predicted fewer symptoms of depression and anxiety at low rumination levels but was not associated with benefits as rumination increased. For depression symptoms, social support seeking predicted more symptoms at high rumination levels. Results were stronger for emotion-focused than problem-focused support seeking and for depression compared with anxiety symptoms. These findings suggest that cognitive risk factors like rumination may explain some inconsistencies in previous social support literature, and highlight the importance of a nuanced approach to studying social support seeking.
