Internet-delivered therapist-guided physical activity for mild to moderate depression: a randomized controlled trial

Objective: The main hypothesis, and the objective of the study, was to test if the participants allocated to the treatment group would show a larger reduction in depressive symptoms than those in the control group. Methods: This study was a randomized nine week trial of an Internet-administered treatment based on guided physical exercise for Major Depressive Disorder (MDD). A total of 48 participants with mild to moderate depression, diagnosed using the Structured Clinical Interview for DSM-IV Axis I Disorders , were randomized either to a treatment intervention or to a waiting-list control group. The main outcome measure for depression was the Beck Depression Inventory-II (BDI-II), and physical activity level was measured using the International Physical Activity Questionnaire (IPAQ). The treatment program consisted of nine text modules, and included therapist guidance on a weekly basis. Results: The results showed significant reductions of depressive symptoms in the treatment group co...

研究目标：本研究的核心假设与目标为检验干预组参与者的抑郁症状减幅是否显著大于对照组。方法：本研究为一项为期9周的随机对照试验，所采用的互联网辅助干预方案基于针对重性抑郁障碍（Major Depressive Disorder, MDD）的指导性体育锻炼。研究共纳入48名经《DSM-IV轴I障碍结构化临床访谈》确诊的轻中度抑郁患者，将其随机分配至干预组或等待列表对照组。抑郁症状的主要评估指标为贝克抑郁量表第二版（Beck Depression Inventory-II, BDI-II），身体活动水平则采用国际体力活动问卷（International Physical Activity Questionnaire, IPAQ）进行测量。本干预方案包含9个文本模块，并配备每周一次的治疗师指导。结果：结果显示干预组抑郁症状出现显著降低……
