几个青少年抑郁症预防计划已经证明了对抑郁症状和整体功能的影响。然而，尽管人们越来越重视阐明干预措施的变化机制，但很少有研究确定这些预防性干预措施的中介因素。在这项研究中，我们研究了人际心理治疗-青少年技能训练(IPT-AST)的人际中介，这是一个循证的抑郁症预防计划。抑郁症预防计划是一项以学校为基础的随机对照试验，共186名青少年(女性占66.7%，少数族裔占32.2%)被分配接受IPT-AST(n=995)或团体咨询(GC)(n=991)。我们考察了从基线到干预中期的人际冲突、社会支持或社会功能的变化是否中介了IPT-AST对干预后抑郁症状和整体功能的影响。干预后，IPT-AST组青年的抑郁症状(d=0.31)低于GC组青年(d=0.31)，总体功能评分(d=0.32)高于GC组青年组(d=0.32)。青少年恋爱功能的改善，同伴冲突的减少，以及反映母子冲突和家庭功能困难的因素得分的改善，都是重要的中介因素。然而，干预对调节因子变化的影响在统计学上并不显著。这些发现补充了关于心理社会干预中介因素的稀少文献，为IPT-AST变化的理论机制提供了部分支持，并强调了未来预防和干预研究的重要方向。
Several adolescent depression prevention programs have demonstrated effects on depressive symptoms and overall functioning. Yet, despite an increasing emphasis on elucidating mechanisms of change in interventions, few studies have identified mediators of these preventive interventions. In this study, we examined interpersonal mediators of Interpersonal Psychotherapy–Adolescent Skills Training (IPT-AST), an evidence-based depression prevention program. The Depression Prevention Initiative is a school-based randomized controlled trial in which 186 adolescents (Mage = 14.01,SD= 1.22; 66.7% female; 32.2% racial minority) were assigned to receive either IPT-AST (n= 95) or Group Counseling (GC) (n= 91). We examined whether change in interpersonal conflict, social support, or social functioning from baseline to midintervention mediated the effects of IPT-AST on depressive symptoms and overall functioning at postintervention. At postintervention, youth in IPT-AST had lower depressive symptoms (d= −.31) and higher overall functioning scores (d= .32) than youth in GC. Improvements in adolescent romantic functioning, reductions in peer conflict, and improvements in a factor score reflecting mother–adolescent conflict and difficulties in family functioning emerged as significant mediators. However, the effects of the intervention on change in the mediators were not statistically significant. These findings add to the sparse literature on mediators of psychosocial interventions, provide partial support for the theoretical mechanisms underlying change in IPT-AST, and highlight important directions for future prevention and intervention research.
