Psychological interventions for adolescents have shown mixed efficacy, and including parents in interventions may be an important avenue to improve treatment outcomes. Evidence from meta-analyses examining the role of parents in interventions for youth is inconsistent and has typically combined findings for both children and adolescents together. No prior meta-analysis has examined the specific role of parents in adolescent interventions as compared with interventions focused solely on adolescents across several disorders. To address this gap, systematic literature reviews were conducted utilizing a combination of searches among keywords including (parent * OR family) AND (intervention OR therap * OR treatment OR prevent*) AND (adolescen*). Inclusion criteria were (1) a randomized controlled trial of an individual psychological intervention compared to the same intervention with a parental component, and (2) adolescents must have at least current symptoms or risk to be included. Literature searches identified 20 trials (N = 1251). Summary statistics suggested that interventions involving parents in treatment have a significantly greater impact on adolescent psychopathology when compared to interventions that targeted adolescents alone (g = − 0.18, p < .01, 95% CI [− 0.30, − 0.07]). Examination with symptom type (internalizing or externalizing) as a moderator found that the significant difference remained for externalizing (g = − 0.20, p = .01, 95% CI [− 0.35, − 0.05]) but not internalizing psychopathology (p = .11). Findings provide evidence of the importance of including parents in adolescent therapy, particularly for externalizing problems.

针对青少年的心理干预显示出混合疗效，让父母参与干预可能是改善治疗结果的重要途径。检查父母在青少年干预中的作用的荟萃分析证据不一致，并且通常将儿童和青少年的研究结果合并在一起。与仅针对青少年的几种疾病的干预措施相比，先前的荟萃分析没有检查父母在青少年干预中的具体作用。为了解决这一差距，利用关键词之间的组合搜索进行了系统文献综述，包括 （parent * OR family） AND （intervention OR therap * OR treatment OR prevent*） AND （adolescen*）。纳入标准是 （1） 个体心理干预与具有父母成分的相同干预相比的随机对照试验，以及 （2） 青少年必须至少具有当前症状或风险才能被纳入。文献检索确定了 20 项试验 （N = 1251）。汇总统计数据表明，与仅针对青少年的干预措施相比，让父母参与治疗的干预措施对青少年精神病理学的影响明显更大 （g = − 0.18， p < .01， 95% CI [− 0.30， − 0.07]）。以症状类型 （内化或外化） 作为调节因素的检查发现，外化 （g = − 0.20， p = .01， 95% CI [− 0.35， − 0.05]） 仍然存在显着差异，但未内化精神病理学 （p = .11）。 研究结果证明了让父母参与青少年治疗的重要性，特别是对于外化问题。
