Intervention fidelity is the core component of a well-designed clinical trial and processes that are used to ensure that the study intervention is delivered as planned. It affects the design and implementation of a study as well as the analysis of the results and interpretation of the findings. The objectives of this study are (a) to describe the methods of assessing the intervention fidelity used in the peer-led chronic pain management program (PAP) and (b) to report the findings on the PAP’s intervention fidelity. To optimize fidelity to the intervention, we used various strategies and measured them in a continuous process using several different approaches: (a) peer volunteer (PV) training workshop, (b) biweekly meetings with the research team, (c) a detailed teaching manual, (d) a fidelity checklist, (e) on-site visits and direct observations, and (f) semi-structured interview. The PVs’ attendance was high, and most of them achieved a high level of implementation in following the fidelity checklist. As part of a large clustered RCT, the fidelity assessment was carried out to help determine the effectiveness of the intervention. Overall, the PVs successfully delivered the intervention, and the results of the study indicate the effectiveness of the PAP. ClinicalTrials.gov NCT03823495 . Registered on 30 January 2019.

评估同伴主导的慢性疼痛管理计划 (PAP) 的保真度

干预保真度是精心设计的临床试验和流程的核心组成部分，用于确保研究干预按计划交付。它影响研究的设计和实施，以及结果的分析和结果的解释。本研究的目的是 (a) 描述评估同伴主导的慢性疼痛管理计划 (PAP) 中使用的干预保真度的方法，以及 (b) 报告 PAP 干预保真度的调查结果。为了优化干预的保真度，我们使用了各种策略，并使用几种不同的方法在连续过程中对其进行了测量：(a) 同伴志愿者 (PV) 培训研讨会，(b) 与研究团队的双周会议，(c) 详细的教学手册，(d) 保真检查表，(e) 现场访问和直接观察，(f) 半结构化面试。PV 的出席率很高，其中大多数人在遵循保真检查表方面取得了较高的执行水平。作为大型集群 RCT 的一部分，进行了保真度评估以帮助确定干预的有效性。总体而言，PV 成功实施了干预，研究结果表明 PAP 的有效性。ClinicalTrials.gov NCT03823495。2019 年 1 月 30 日注册。研究结果表明行动计划的有效性。ClinicalTrials.gov NCT03823495。2019 年 1 月 30 日注册。研究结果表明行动计划的有效性。ClinicalTrials.gov NCT03823495。2019 年 1 月 30 日注册。
