Self-help cognitive behavior therapy (CBT) is a useful approach for the treatment of psychological problems. Recent research on the effectiveness of self-help internet-based CBT (ICBT) indicates that the paradigm moderately improves psychological problems. Furthermore, previous studies have shown that food and drinks containing supplements improve various health conditions. We investigated the effect of a brief self-help ICBT administered with a supplement drink on psychological well-being and somatic symptoms.
In total, 101 healthy workers were enrolled in the 4-week ICBT program, which consisted of psychoeducation on stress management, behavior activation, and cognitive restructuring. The supplement soft drink was taken every day during the program. The participants were instructed to watch on-demand video clips and read the self-help guidebook and supporting comic strip weekly on the Internet or smartphone. The Japanese version of the Profile of Mood States (POMS) was administered before and after completion of the program. Scores on the POMS tension-anxiety (POMS-TA), depression (POMS-D), and fatigue (POMS-F) subscales were used to assess the effect of the program. Somatic symptoms were assessed using the Brief Job Stress Questionnaire.
In total, 75 participants continued the program for 4 weeks; however, of those, 27 failed to complete all weekly tasks or meet the post-assessment deadlines. Therefore, the data of 48 participants were included in the analysis. Pre-post intervention comparisons using paired -tests revealed significant improvement on the POMS-TA, but not the POMS-D or POMS-F subscales. Moreover, participants reported a significant reduction in the severity of low back pain.
Our brief intervention moderately improved anxiety levels and the symptom of low back pain. These findings suggest that the brief ICBT program is effective in non-patient populations. Future directions for brief ICBT are discussed.

自助式认知行为疗法（CBT）是治疗心理问题的一种有效方法。近期关于基于互联网的自助式CBT（ICBT）有效性的研究表明，该模式能适度改善心理问题。此外，先前的研究表明，含有补充剂的食物和饮料能改善各种健康状况。我们研究了一种结合补充剂饮料的简短自助式ICBT对心理健康和躯体症状的影响。
共有101名健康工作者参加了为期4周的ICBT项目，该项目包括压力管理、行为激活和认知重构方面的心理教育。在项目期间，每天饮用补充剂软饮料。参与者被要求每周在互联网或智能手机上观看按需提供的视频片段，并阅读自助指南和配套的连环漫画。在项目开始前和结束后，使用日语版的情绪状态量表（POMS）进行测评。POMS紧张焦虑（POMS-TA）、抑郁（POMS-D）和疲劳（POMS-F）分量表的得分用于评估该项目的效果。使用简短工作压力问卷评估躯体症状。
共有75名参与者持续参与该项目4周；然而，其中27人未能完成所有每周任务或未在评估截止日期前完成。因此，分析纳入了48名参与者的数据。使用配对t检验进行干预前后比较发现，POMS-TA有显著改善，但POMS-D或POMS-F分量表没有。此外，参与者报告腰痛严重程度显著降低。
我们的简短干预适度改善了焦虑水平和腰痛症状。这些发现表明，简短的ICBT项目对非患者群体有效。讨论了简短ICBT的未来发展方向。
