The Patient Evaluation Measure (PEM) is a region-specific patient reported outcome measure (PROM) for hand and wrist disorders, first introduced in English for patients with hand surgery in 1995. The purpose of the study was to assess the psychometric properties of the translated and cross-culturally adapted Slovenian version of PEM (PEM-Slo).
The study was designed as a single-centre observational prospective study conducted from July 2020 to March 2021. The psychometric evaluation was performed on fifty-one patients with miscellaneous hand and wrist disorders. Reliability was tested for internal consistency and test-retest reliability. Convergent and divergent validity, responsiveness, floor and ceiling effect, and interpretability with the determination of minimal detectable change (MDC) and minimal clinically important difference (MCID) were assessed.
The PEM-Slo has excellent internal consistency (Cronbach's α 0.932) and good to excellent test-retest reliability (intraclass correlation coefficient=0.874). Convergent validity was proved with high to moderate correlations of PEM-Slo with DASH, grip strength and self-care, usual activities, and pain EQ-5D-5L subscales, whereas no correlation of PEM-Slo with EQ-5D-5L mobility and anxiety/depression subscale confirmed divergent validity. The PEM-Slo responsiveness was high (standardised response mean=1.42, effect size=1.25). MDC was 18.01 and MCID was 17.31. No floor or ceiling effect was found.
The PEM-Slo is a reliable, valid and responsive PROM for Slovenian-speaking patients with hand and wrist disorders.
患者评估量表（PEM）是一种针对手部和腕部疾病的特定区域患者报告结局量表（PROM），于1995年首次以英文引入用于手部手术患者。本研究的目的是评估经翻译和跨文化适应的斯洛文尼亚语版PEM（PEM-Slo）的心理测量特性。
本研究设计为一项单中心观察性前瞻性研究，于2020年7月至2021年3月进行。对51例患有各种手部和腕部疾病的患者进行了心理测量评估。测试了内部一致性和重测信度的可靠性。评估了收敛效度和区分效度、反应性、地板效应和天花板效应，以及通过确定最小可检测变化（MDC）和最小临床重要差异（MCID）进行的可解释性。
PEM-Slo具有出色的内部一致性（Cronbach's α 0.932）和良好至出色的重测信度（组内相关系数=0.874）。PEM-Slo与DASH、握力以及自我护理、日常活动和疼痛EQ-5D-5L子量表具有高至中度相关性，证明了收敛效度，而PEM-Slo与EQ-5D-5L活动能力和焦虑/抑郁子量表无相关性，证实了区分效度。PEM-Slo的反应性较高（标准化反应均值=1.42，效应量=1.25）。MDC为18.01，MCID为17.31。未发现地板效应或天花板效应。
PEM-Slo是一种可靠、有效且具有反应性的PROM，适用于讲斯洛文尼亚语的手部和腕部疾病患者。
