Changes in adolescent interpersonal behavior before and after an acute course of psychotherapy were investigated as outcomes and mediators of remission status in a previously described treatment study of depressed adolescents. Maternal depressive symptoms were examined as moderators of the association between psychotherapy condition and changes in adolescents' interpersonal behavior.
Adolescents (n = 63, mean age = 15.6 years, 77.8% female, 84.1% White) engaged in videotaped interactions with their mothers before randomization to cognitive behavior therapy (CBT), systemic behavior family therapy (SBFT), or nondirective supportive therapy (NST) and after 12-16 weeks of treatment. Adolescent involvement, problem solving, and dyadic conflict were examined.
Improvements in adolescent problem solving were significantly associated with CBT and SBFT. Maternal depressive symptoms moderated the effect of CBT, but not SBFT, on adolescents' problem solving; adolescents experienced increases in problem solving only when their mothers had low or moderate levels of depressive symptoms. Improvements in adolescents' problem solving were associated with higher rates of remission across treatment conditions, but there were no significant indirect effects of SBFT on remission status through problem solving. Exploratory analyses revealed a significant indirect effect of CBT on remission status through changes in adolescent problem solving, but only when maternal depressive symptoms at study entry were low.
Findings provide preliminary support for problem solving as an active treatment component of structured psychotherapies for depressed adolescents and suggest one pathway by which maternal depression may disrupt treatment efficacy for depressed adolescents treated with CBT.
在一项先前描述的针对抑郁青少年的治疗研究中,调查青少年在急性心理治疗疗程前后人际行为的变化,将其作为缓解状态的结果和中介因素。将母亲的抑郁症状作为心理治疗条件与青少年人际行为变化之间关联的调节因素进行检验。
青少年(n = 63,平均年龄 = 15.6岁,77.8%为女性,84.1%为白人)在被随机分配到认知行为疗法(CBT)、系统行为家庭疗法(SBFT)或非指导性支持疗法(NST)之前,以及在治疗12 - 16周后,与他们的母亲进行录像互动。对青少年的参与度、解决问题的能力和二元冲突进行了检查。
青少年解决问题能力的改善与CBT和SBFT显著相关。母亲的抑郁症状调节了CBT对青少年解决问题能力的影响,但未调节SBFT的影响;只有当母亲的抑郁症状水平较低或中等时,青少年的解决问题能力才会提高。青少年解决问题能力的改善与各治疗条件下较高的缓解率相关,但SBFT通过解决问题对缓解状态没有显著的间接影响。探索性分析显示,CBT通过青少年解决问题能力的变化对缓解状态有显著的间接影响,但仅在研究开始时母亲的抑郁症状较低时才成立。
研究结果为解决问题作为抑郁青少年结构化心理治疗的一个积极治疗成分提供了初步支持,并表明母亲抑郁可能破坏CBT治疗抑郁青少年疗效的一种途径。
