ABSTRACT

Process evaluation enables us to gain insights into the complex organisational intervention processes, but has mostly taken place post intervention, thus failing to support implementation. Using the theory of planned behaviour, we developed and validated a 7-item process evaluation questionnaire (the Intervention Preparedness Tool) that aims to evaluate the preparatory phases of the intervention and may be used to optimise the intervention process. The study was conducted in two Italian hospitals participating in an organisational intervention (N = 1,654 healthcare workers).

We conducted exploratory factor analysis (EFA) on one half of the sample and cross-validated the best factor structure identified through confirmatory factor analysis (CFA) on the other half of the sample. Results showed that the Intervention Preparedness Tool composed of 7 items has a three-factor structure (readiness for change, intervention-context fit, and communication). To perform nomological validation, we correlated the Intervention Preparedness Tool with seven psychosocial working conditions (demand, control, peer support, supervisor support, roles, relationships, changes) and job satisfaction. We found that the dimensions of the Intervention Preparedness Tool were significantly related to these working conditions and job satisfaction suggesting that the organisational context may be related to participants’ appraisals of the early phases of participatory interventions.

摘要

过程评估使我们能够洞察复杂的组织干预过程，但大多是在干预后进行，无法支持实施。利用计划行为理论，我们开发并验证了包含 7 项的过程评估问卷（干预准备工具），旨在评估干预的准备阶段，并可用于优化干预过程。该研究在参与组织干预的两家意大利医院进行（N  = 1,654 名医护人员）。

我们对一半样本进行了探索性因素分析 (EFA)，并交叉验证了通过对另一半样本进行验证性因素分析 (CFA) 确定的最佳因素结构。结果显示，干预准备工具由 7 个项目组成，具有三因素结构（变革准备、干预情境契合和沟通）。为了进行法理验证，我们将干预准备工具与七种心理社会工作条件（需求、控制、同伴支持、主管支持、角色、关系、变化）和工作满意度相关联。
