Patient-reported experience measures (PREMs) are recommended for use in evaluating person-centred care. To date, a PREM has not been validated for residential alcohol and other drug (AOD) treatment. Utilising items developed through a previously published qualitative study informing the development of the PREM for Addiction Treatment (PREMAT), the current study conducted a psychometric evaluation and validation of the PREMAT.
Cross-sectional survey data were collected from six Australian residential AOD treatment facilities (N = 178). Psychometric evaluation included examining the factor structure, internal consistency, and construct validity of the PREMAT. Test re-test reliability was conducted at one treatment site (n = 24).
The total PREMAT score demonstrated strong internal consistency (α = 0.91). Principle components analysis identified six factors (all α > 0.72). The PREMAT total score and factor scores were negatively skewed. Concurrent validity was demonstrated by strong positive correlations with measures of satisfaction (ρ = 0.81, Client Satisfaction Questionnaire-8; ρ = 0.78, Treatment Perceptions Questionnaire), and divergent validity was demonstrated with weaker correlations with Drug-Taking Confidence Questionnaire (ρ = 0.25) and Kessler-10 (ρ = -0.20). Test-retest reliability was strong for the total PREMAT (ρ = 0.89).
Results support the use of the PREMAT as a valid measure of experience in residential AOD treatment settings. Future research should examine the use of the PREMAT across the course of treatment to examine if experience is related to client characteristics, outcome, dropout or re-engagement in treatment.
患者报告的体验测量（PREMs）被推荐用于评估以患者为中心的护理。迄今为止，尚未针对住院酒精和其他药物（AOD）治疗验证过 PREM。本研究利用先前发表的一项定性研究中开发的项目，该研究为治疗成瘾的 PREM（PREMAT）的开发提供了信息，对 PREMAT 进行了心理测量评估和验证。
从澳大利亚六家住院 AOD 治疗机构（N=178）收集了横断面调查数据。心理测量评估包括检查 PREMAT 的结构、内部一致性和构念效度。在一个治疗地点（n=24）进行了测试再测试的可靠性。
PREMAT 的总分表现出很强的内部一致性（α=0.91）。主成分分析确定了六个因素（所有α>0.72）。PREMAT 的总分和因子得分呈负偏态。与满意度测量（ρ=0.81，客户满意度问卷-8；ρ=0.78，治疗感知问卷）呈强烈正相关，与药物使用信心问卷（ρ=0.25）和 Kessler-10（ρ=-0.20）呈较弱相关，表明具有良好的同时效度。PREMAT 的总分具有很强的测试再测试可靠性（ρ=0.89）。
结果支持将 PREMAT 作为住院 AOD 治疗环境中体验的有效测量工具。未来的研究应该在治疗过程中检查 PREMAT 的使用情况，以研究经验是否与患者特征、结果、脱落或重新参与治疗有关。
