Conduct a pilot trial testing whether a brief cognitive-behavioral (CB) group reduced depressive symptoms and secondary outcomes relative to bibliotherapy and brochure controls in college students with elevated depressive symptoms.
82 college students (M age=19.0, SD=0.9; 70% female, 80% White) with elevated self-assessed depressive symptoms were randomized to a 6-session CB group, bibliotherapy, or educational brochure control condition, completing assessments at pretest, posttest, and at 6- and 12-month follow-up.
Planned contrasts found no significant effects for CB group on depressive symptoms compared to either bibliotherapy or brochure controls at posttest (d=-.08 and .06, respectively) or over follow-up (d=-.04 and -.10, respectively). There were no intervention effects for social adjustment and substance use, though CB group participants had improved knowledge of CB concepts at posttest, versus brochure controls. Condition differences in major depression onset were nonsignificant but suggested support for CB interventions (CB group=7.4%, bibliotherapy=4.5%, brochure control=15.2%).
Unexpectedly modest support was found for a brief CB group depression prevention intervention, compared to bibliotherapy or brochure control, when provided to self-selected college students, suggesting that alternative screening or interventions approaches are needed for this population.
开展一项试点试验，测试与阅读疗法及宣传手册对照相比，简短的认知行为（CB）小组干预能否减轻抑郁症状及大学生抑郁症状加重时的次要结果。
82名自我评估抑郁症状加重的大学生（平均年龄=19.0，标准差=0.9；70%为女性，80%为白人）被随机分配至6节CB小组干预、阅读疗法或教育宣传手册对照组，在预测试、后测试以及6个月和12个月随访时完成评估。
计划对比发现，与阅读疗法或宣传手册对照相比，CB小组在后测试时（效应量分别为-.08和.06）或随访期间（效应量分别为-.04和-.10）对抑郁症状无显著影响。社会适应和物质使用方面无干预效果，不过与宣传手册对照相比，CB小组参与者在后测试时对CB概念的了解有所改善。重度抑郁症发作的条件差异不显著，但表明对CB干预有支持作用（CB小组=7.4%，阅读疗法=4.5%，宣传手册对照=15.2%）。
当对自我选择的大学生提供简短的CB小组抑郁症预防干预时，与阅读疗法或宣传手册对照相比，意外发现支持力度不大，这表明该人群需要其他筛查或干预方法。
