Implementation fidelity is a critical component of intervention science, which aims to understand how interventions unfold in practice to improve outcomes. A key element of fidelity is facilitator competent adherence—the extent to which a program is delivered as prescribed with the specified level of quality. We conducted a two-part systematic review examining these aspects in parenting programs aiming to reduce child behavior problems and maltreatment. Part One reviews measures of facilitator competent adherence and Part Two examines the psychometric properties of the observational measures found. Searches identified 9153 articles from electronic databases, citation tracking, and expert input. After screening using pre-specified criteria, 156 (Part One) and 41 (Part Two) articles remained. In Part One, measure, facilitator, and intervention characteristics were extracted and synthesized from 65 measures. Most measures were observational, used by facilitators and researchers, and employed Likert-scale ratings. In Part Two, evidence on the reliability (internal consistency, inter-rater, intra-rater, test–retest) and validity (content, construct, convergent/divergent, criterion) of 30 observational measures identified from Part One was synthesized and evaluated. An adapted COSMIN checklist was used to assess study and measure quality. We found most studies to be of reasonably high quality. This is the first review to summarize and critically appraise measures of facilitator competent adherence used in the parenting program literature and establish their psychometric properties. The findings underscore the need to advance research on measures of facilitator competent adherence; reliable, valid, and high-quality implementation measures allow for evidence-based decisions regarding the delivery and scale-up of parenting programs.

实施保真度是干预科学的重要组成部分，旨在了解干预措施在实践中如何展开以改善结果。保真度的一个关键要素是促进者有能力的遵守——按照规定的质量水平交付计划的程度。我们进行了一项分为两部分的系统回顾，检查旨在减少儿童行为问题和虐待的育儿计划中的这些方面。第一部分回顾促进者有能力遵守的措施，第二部分检查所发现的观察措施的心理测量特性。搜索从电子数据库、引用跟踪和专家输入中识别出 9153 篇文章。使用预先指定的标准筛选后，剩下 156 篇（第一部分）和 41 篇（第二部分）文章。在第一部分中，测量，促进者，从 65 项措施中提取和综合干预特征。大多数措施都是观察性的，由协调员和研究人员使用，并采用李克特量表评级。在第二部分中，对从第一部分中确定的 30 个观察措施的可靠性（内部一致性、评分者间、评分者内、重测）和有效性（内容、结构、收敛/发散、标准）的证据进行了综合和评估。使用经过改编的 COSMIN 检查表来评估研究和衡量质量。我们发现大多数研究的质量相当高。这是第一个总结和批判性评价在育儿计划文献中使用的促进者能力依从性措施并确定其心理测量特性的综述。调查结果强调需要推进对促进者有能力遵守措施的研究；可靠、有效和高质量的实施措施可以让有关实施和扩大育儿计划的循证决策成为可能。PROSPERO 注册号：CRD42020167872。
