Abstract

Aim: This pilot RCT evaluated the feasibility, acceptability, and preliminary effects of Metacognitive Interpersonal Group Therapy for Adolescents (MIT-GA) compared with waiting list plus treatment-as-usual (WL+TAU).

Methods: One hundred adolescents (14-18 years) meeting DSM-IV criteria for PDs (excluding antisocial PD) were randomized to MIT-GA or WL+TAU for 4 months. Primary outcomes included treatment acceptability, psychosocial functioning (CGAS, IIP-64), and symptom severity (SCL-90-R GSI). Secondary outcomes were depression (Y-BDI), caregiver stress (PSS), and parental self-efficacy (BPSES). Mechanisms of change included metacognition (MAS-A), alexithymia (TAS-20), and impulsivity (BIS-11).

Results: MIT-GA participants showed greater improvements in psychosocial functioning (d = 0.80) and parental stress (d = 0.65) versus WL+TAU. No significant between-group differences were found in overall symptom severity. MIT-GA also improved metacognition, alexithymia, and attentional impulsivity. No adverse events were reported.

Conclusions: These findings support the feasibility and potential utility of MIT-GA for adolescents with PDs.

青少年人格障碍的元认知人际团体治疗：meta - a随机对照试验的结果。

目的：本试验评估青少年元认知人际团体治疗（MIT-GA）与等候名单加照例治疗（WL+TAU）的可行性、可接受性和初步效果。方法：100名符合DSM-IV PD（不包括反社会PD）标准的青少年（14-18岁）随机分为MIT-GA组或WL+TAU组，为期4个月。主要结局包括治疗可接受性、社会心理功能（CGAS, IIP-64）和症状严重程度（SCL-90-R GSI）。次要结局是抑郁（Y-BDI）、照顾者压力（PSS）和父母自我效能（bpse）。改变的机制包括元认知（MAS-A）、述情障碍（TAS-20）和冲动性（BIS-11）。结果：与WL+TAU相比，MIT-GA参与者在心理社会功能（d = 0.80）和父母压力（d = 0.65）方面表现出更大的改善。总体症状严重程度组间无显著差异。MIT-GA也改善了元认知、述情障碍和注意力冲动。无不良事件报告。结论：这些发现支持MIT-GA治疗青少年pd的可行性和潜在效用。

期刊介绍： The Journal of Nervous and Mental Disease publishes peer-reviewed articles containing new data or ways of reorganizing established knowledge relevant to understanding and modifying human behavior, especially that defined as impaired or diseased, and the context, applications and effects of that knowledge. Our policy is summarized by the slogan, "Behavioral science for clinical practice." We consider articles that include at least one behavioral variable, clear definition of study populations, and replicable research designs. Authors should use the active voice and first person whenever possible.
