Hoarding disorder can cause problems with work performance, personal hygiene, health and well-being. The disorder is a growing social problem in Japan. Having difficulty discarding rubbish, decluttering and organising can signal a future hoarding disorder, and early intervention is important. We developed an educational workshop on decluttering and organising for teens and adults with difficulty organising. The objective of this study is to evaluate the effectiveness of a workshop for reducing clutter and improving quality of life among younger people with difficulty decluttering and organising.
An open-label, parallel-group, randomised controlled trial will be conducted among volunteers aged 12-55 years with mild difficulty decluttering and organising. Those in the intervention group will attend the workshop and receive a visit from a professional cleaning company to declutter their living space. The control group will have only the latter. The primary outcome will be the score on the Japanese version of the Saving Inventory-Revised. Secondary outcomes will be scores on the Clutter Image Rating Scale, the Japanese version of the Rosenberg Self-Esteem Scale and the Roles of Private Space Scale. The results will be examined for differences between the two groups in changes from baseline to 7 months. We will examine crude effects and adjust for gender and age using a general linear model for continuous variables and a logistic regression model for dichotomous variables. Sample size was calculated assuming a significance level of 5% (two tailed), a power of 80% and an effect size of 0.75. In total, 60 subjects (30 in each group) will be required.
The study protocol has been approved by the Medical Ethical Committee of Teikyo University (No. 15-065). The findings will be disseminated widely through peer-reviewed publication and conference presentations.

囤积障碍会导致工作表现、个人卫生、健康和幸福感方面出现问题。该障碍在日本是一个日益严重的社会问题。难以丢弃垃圾、整理和收纳可能预示着未来会出现囤积障碍，早期干预很重要。我们为整理和收纳有困难的青少年及成年人开展了一个关于整理和收纳的教育工作坊。本研究的目的是评估一个工作坊在减少杂乱和改善难以整理和收纳的年轻人生活质量方面的效果。
将对年龄在12 - 55岁、在整理和收纳方面有轻度困难的志愿者进行一项开放标签、平行组、随机对照试验。干预组的参与者将参加工作坊，并接受一家专业清洁公司的上门服务，以清理他们的生活空间。对照组仅接受后者。主要结局将是日本版修订版储蓄量表的得分。次要结局将是杂乱图像评分量表、日本版罗森伯格自尊量表和私人空间角色量表的得分。将检验两组从基线到7个月变化的差异。我们将检验原始效应，并使用连续变量的一般线性模型和二分变量的逻辑回归模型对性别和年龄进行调整。样本量是在假设显著性水平为5%（双侧）、检验效能为80%和效应量为0.７5的情况下计算得出的。总共需要60名受试者（每组30名）。
本研究方案已获得帝京大学医学伦理委员会批准（编号15 - 065）。研究结果将通过同行评审发表和会议报告广泛传播。
