Initial findings indicate the effectiveness of internet-based interventions for body dysmorphic disorder (BDD). In order to substantiate these findings, a seven-module guided internet-based intervention was created and examined. We report the mixed data of participants with clinical and subclinical BDD of the treatment group (n = 18). We investigated the feasibility, the quality of the program content, the design and usability, and its effects on symptom severity and related psychopathology. Adherence to the intervention was low and dropout rate high (55.6%). The program content, perceived website usability, and visual aesthetic were rated high. Credibility and expectancy were on a medium level. Satisfaction with appearance improved significantly in the intention-to-treat analysis (d = 0.58). In sum, symptom-related outcomes and program evaluation showed a positive trend albeit the study conduction was difficult. Future programs should investigate the role of additional motivation strategies and more flexible support addressing the known treatment barriers.
初步研究结果表明，基于互联网的干预措施对躯体变形障碍（BDD）有效。为了证实这一发现，我们创建并检验了一个包含七个模块的有指导的基于互联网的干预措施。我们报告了治疗组中具有临床和亚临床 BDD 的参与者的混合数据（n=18）。我们调查了该措施的可行性、方案内容质量、设计和可用性，以及其对症状严重程度和相关精神病理学的影响。对干预措施的坚持度低，脱落率高（55.6%）。方案内容、感知网站可用性和视觉美学得到了高度评价。可信度和期望处于中等水平。意向治疗分析显示，对外观的满意度显著提高（d=0.58）。总的来说，尽管研究实施困难，但症状相关结果和方案评估显示出积极趋势。未来的方案应研究额外动机策略的作用以及更灵活的支持，以解决已知的治疗障碍。
