Abstract

High costs, long wait times, and lack of access to mental health supports in Ontario are leaving millions with unmet treatment needs. To address this need, Ontario launched BounceBack, a large-scale coach-supported intervention grounded in cognitive behavioral therapy (CBT) to target symptoms of anxiety, depression, and functional impairment. The objective of this program evaluation was to examine the effectiveness of the BounceBack program in Ontario by exploring (a) changes in participants’ depression and anxiety symptoms and functional impairment (as measured by the PHQ-9, GAD-7, and WSAS, respectively); and (b) rates for recovery and reliable improvement. Multilevel modelling (MLM) results indicated that participants reported significant improvements in their depression, anxiety, and functioning symptoms over time, which are not better accounted for by other demographic factors. Higher baseline severity of symptoms were associated with greater decreases in these symptoms. The strong recovery and reliable improvement rates identified further support the effectiveness of BounceBack as a potent intervention that leads to improvements in symptoms of anxiety and/or depression for the majority of its participants.

低强度的高影响：安大略省抑郁和焦虑症反弹计划的效果

在安大略省，高昂的费用、漫长的等待时间以及缺乏获得心理健康支持的途径，使得数百万人的治疗需求得不到满足。为了满足这一需求，安大略省推出了以认知行为疗法（CBT）为基础的大规模教练支持干预措施 "BounceBack"，以治疗焦虑、抑郁和功能障碍症状。本项目评估的目的是通过探究 (a) 参与者抑郁和焦虑症状及功能障碍（分别通过 PHQ-9、GAD-7 和 WSAS 测量）的变化；以及 (b) 康复率和可靠改善率，来检验 BounceBack 项目在安大略省的有效性。多层次建模（MLM）结果表明，随着时间的推移，参与者的抑郁、焦虑和功能症状均有显著改善，而其他人口统计学因素并不能更好地解释这些改善。基线症状的严重程度越高，这些症状的减轻程度就越大。已确定的强劲恢复率和可靠的改善率进一步证明了 "反弹疗法 "的有效性，它是一种有效的干预措施，能使大多数参与者的焦虑和/或抑郁症状得到改善。

期刊介绍： Behavior Therapy is a quarterly international journal devoted to the application of the behavioral and cognitive sciences to the conceptualization, assessment, and treatment of psychopathology and related clinical problems. It is intended for mental health professionals and students from all related disciplines who wish to remain current in these areas and provides a vehicle for scientist-practitioners and clinical scientists to report the results of their original empirical research. Although the major emphasis is placed upon empirical research, methodological and theoretical papers as well as evaluative reviews of the literature will also be published. Controlled single-case designs and clinical replication series are welcome.
