Abstract

Purpose: Psychosocial determinants influence healthcare workers’ compliance with surgical site infection (SSI) preventive interventions. In order to design needs-based interventions promoting compliance, such determinants must first be assessed using valid and reliable questionnaire scales. To compare professional groups without bias, the scales must also be measurement-equivalent. We examine the validity/reliability and measurement equivalence of four scales using data from physicians and nurses from outside the university sector. Additionally, we explore associations with self-reported SSI preventive compliance.
Participants and Methods: N = 90 physicians and N = 193 nurses (response rate: 31.5%) from nine general/visceral or orthopedic/trauma surgery departments in six non-university hospitals in Germany participated. A written questionnaire was used to assess the compliance with SSI preventive interventions and the determinants of compliance based on the Capability-Opportunity-Motivation-Behavior-Model. Psychometric testing involved single- and multiple-group confirmatory factor analyses, and explorative analyses used t-tests and multiple linear regression.
Results: The scales assessing individual determinants of compliance (capability, motivation, and planning) were found to be reliable (each Cronbach’s α ≥ 0.85) and valid (each Root-Mean-Square-Error of Approximation ≤ 0.065, each Comparative-Fit-Index = 0.95) and revealed measurement equivalence for physicians and nurses. The scale assessing external determinants (opportunity) did not demonstrate validity, reliability, or measurement equivalence. Group differences were found neither in compliance (p = 0.627) nor determinants (p = 0.192; p = 0.866; p = 0.964). Capability (β = 0.301) and planning (β = 0.201) showed associations with compliance for nurses only.
Conclusion: The scales assessing motivation, capability, and planning regarding SSI preventive compliance provided reliable and valid scores for physicians and nurses in surgery. Measurement equivalence allows group comparisons of scale means to be interpreted without bias.

评估工作人员遵守手术部位感染预防措施的社会心理决定因素的量表的心理计量特性：WACH-研究

目的：社会心理决定因素会影响医护人员对手术部位感染（SSI）预防干预措施的依从性。为了设计基于需求的干预措施以促进遵从性，必须首先使用有效可靠的问卷量表对这些决定因素进行评估。为了不带偏见地对专业群体进行比较，量表还必须具有测量等效性。我们使用来自大学以外的医生和护士的数据，对四个量表的有效性/可靠性和测量等效性进行了研究。此外，我们还探讨了与自我报告的 SSI 预防依从性之间的关联：来自德国六所非大学医院九个普通/内脏或骨科/创伤外科的 90 名医生和 193 名护士（回复率：31.5%）参与了此次研究。调查采用书面问卷的形式，以能力-机会-动机-行为模型为基础，对SSI预防干预措施的依从性和依从性的决定因素进行评估。心理测试包括单组和多组确认性因素分析，探索性分析采用 t 检验和多元线性回归：结果发现，评估遵医行为个体决定因素（能力、动机和计划）的量表是可靠的（每个 Cronbach's α ≥ 0.85），有效的（每个 Root-Mean-Square-Error of Approximation ≤ 0.065，每个 Comparative-Fit-Index = 0.95），并显示出医生和护士的测量等效性。评估外部决定因素（机会）的量表未显示有效性、可靠性或测量等效性。在依从性（p = 0.627）和决定因素（p = 0.192；p = 0.866；p = 0.964）方面均未发现组间差异。只有护士的能力（β = 0.301）和计划（β = 0.201）与依从性有关：结论：评估 SSI 预防依从性的动机、能力和计划的量表为外科医师和护士提供了可靠有效的评分。关键词：感染预防与控制；手术部位感染；依从性；护士；医生；能力-机会-动机-行为（COM-B）模型；测量等效性
