摘要

背景焦虑和抑郁症在巴西非常普遍，在年轻人中易感程度更高。尽管患病率很高，但巴西的精神卫生保健系统面临着重大挑战，只有少数人接受治疗。量身定制的互联网认知行为疗法（ICBT）为解决这种治疗与需求之间的差距提供了一个有希望的策略。本研究考察了个性化ICBT干预与按需支持对减少年轻人焦虑和抑郁症状的疗效。方法：这项两组随机对照试验涉及巴西年轻人（18-24岁），他们被随机分配到治疗组（n = 46）和候补对照组（n = 46）。为期8周的治疗包括在在线平台上进行个性化定制的ICBT，并通过聊天按需提供治疗师支持。主要结局是焦虑和抑郁症状。次要指标包括压力、失眠、智能手机和社交媒体使用、完美主义和生活质量。进行了为期六个月的随访。结果多元回归分析显示，与对照组相比，治疗组在焦虑、抑郁、压力、失眠等方面均有显著减少，生活质量也有显著改善，且效应量为中大型。结论icbt是巴西青少年常见心理健康症状的有效干预手段。需要进一步研究以探讨执行情况及其对其他人群的影响。

Internet-based cognitive behavioral therapy for anxiety and depressive symptoms in Brazilian emerging adults: A pilot randomized controlled trial

Background

Anxiety and depressive disorders are highly prevalent in Brazil, with higher vulnerability among young adults. Despite the high prevalence, Brazil faces significant challenges in its mental health care system, with only a minority receiving treatment. Tailored internet-delivered cognitive behavioral therapy (ICBT) offers a promising strategy to address this treatment versus demand gap. This study examines the efficacy of individually tailored ICBT intervention with on-demand support for reducing anxiety and depressive symptoms in young adults.

Methods

This two-arm randomized controlled trial involved Brazilian young adults (aged 18–24 years) who were randomly assigned to either a treatment group (n = 46) or a waitlist control group (n = 46). The 8-week treatment included individually tailored ICBT with therapist support on-demand via chat, conducted on an online platform. Primary outcomes were symptoms of anxiety and depression. Secondary measures included stress, insomnia, smartphone and social media use, perfectionism, and quality of life. A six-month follow-up was conducted.

Results

Multiple regression analysis indicated that the treatment group, in comparison to the control group, showed significant reductions in anxiety, depression, stress, and insomnia, as well as improvements in quality of life, with moderate to large effects sizes.

Conclusion

ICBT is a viable intervention for young Brazilians experiencing common mental health symptoms. Further research is needed to explore implementation and impact on other populations.
