Background

Perfectionism is elevated across a range of psychopathologies and has been shown to impede treatment outcomes. There is also evidence suggesting elevated perfectionism may contribute to the onset and maintenance of non-suicidal self-injury. There is a growing body of evidence suggesting that Internet-delivered cognitive-behavioural therapy for perfectionism reduces perfectionism and symptoms of psychological disorders and that reductions are maintained at 3-month and 6-month follow-up. There may also be reductions in non-suicidal self-injury, although no study has investigated this potential benefit. Given that associations between perfectionism and psychopathology are observed across both adults and adolescents, the need for the development of interventions targeting adolescents is essential for early intervention and prevention.

Methods

The present study will employ a randomised controlled trial to examine the efficacy of 8-week guided Internet-delivered cognitive-behavioural therapy for perfectionism in adolescents compared to a waitlist control group. The primary outcome is perfectionism, and secondary outcomes include symptoms of psychological disorders, well-being, and non-suicidal self-injury. Outcomes will be assessed at pre-intervention, post-intervention, 1-month follow-up, 3-month follow-up, and 6-month follow-up. A minimum of 240 participants will be recruited online through social media, Australian universities, and schools across Australia. Generalised linear mixed models will be used to test for changes in outcomes between the intervention group and the waitlist control.

Discussion

The outcomes of this trial will contribute to the literature on perfectionism and psychopathology in adolescents, as well as the efficacy of guided Internet-delivered interventions for adolescents.

Trial registration

The trial was registered on the 20th of June 2019 at the Australia New Zealand Clinical Trials Registry (ACTRN12619000881134).

Trial status

This is protocol version 1.0. Participant recruitment began on 31 July 2019 and is still actively running with an anticipated completion date in the fourth quarter of 2020.

针对青少年非临床样本中完美主义的引导式互联网认知行为疗法：一项随机对照试验的研究方案。

背景

完美主义在一系列精神病理学中得到提升，并已被证明会阻碍治疗结果。还有证据表明，完美主义的提高可能会导致非自杀性自伤的发生和维持。越来越多的证据表明，通过互联网提供的完美主义认知行为疗法可以减少完美主义和心理障碍的症状，并且在 3 个月和 6 个月的随访中保持这种减少。非自杀性自伤也可能减少，尽管没有研究调查过这种潜在的好处。鉴于成人和青少年都观察到完美主义和精神病理学之间的关联，因此需要开发针对青少年的干预措施对于早期干预和预防至关重要。

方法

本研究将采用一项随机对照试验，与候补名单对照组相比，检验为期 8 周的互联网引导认知行为疗法对青少年完美主义的疗效。主要结果是完美主义，次要结果包括心理障碍症状、幸福感和非自杀性自伤。将在干预前、干预后、1 个月随访、3 个月随访和 6 个月随访时评估结果。将通过社交媒体、澳大利亚大学和澳大利亚各地的学校在线招募至少 240 名参与者。广义线性混合模型将用于测试干预组和候补名单控制之间的结果变化。

讨论

该试验的结果将有助于有关青少年完美主义和精神病理学的文献，以及对青少年进行指导的互联网干预措施的有效性。

试用注册

该试验于 2019 年 6 月 20 日在澳大利亚新西兰临床试验注册中心 (ACTRN12619000881134) 注册。

试用状态

这是协议版本 1.0。参与者招募于 2019 年 7 月 31 日开始，目前仍在积极进行中，预计完成日期为 2020 年第四季度。
