研究设计：横断面调查的心理测量评估。目的：本研究的目的是检查 Penn 肩部评分 (PSS) 的可靠性和有效性的心理测量特性。背景：肩部结果测量用于评估患者自我报告的疼痛、满意度和功能水平。 PSS 是一份 100 分的肩部自我报告问卷，由疼痛、满意度和功能 3 个分量表组成。该量表已在文献中使用。然而，需要建立 PSS 子量表和整体量表的信度和效度（包括反应性）的测量特性。 方法和测量：接受门诊物理治疗疗程的肩部疾病患者 (n = 40) 在初次就诊时完成 PSS，并在 72 小时内再次完成 PSS，以评估重测可靠性。初次就诊时还完成了恒定肩部评分 (CSS) 和美国肩肘外科医生肩部评分 (ASES)，并与 PSS 进行比较，以评估收敛结构的有效性。另一组患者 (n = 109) 在初次就诊时和 4 周后完成了 PSS。这些分数用于评估内部一致性和响应性。结果：可靠性分析显示重测 IC2,1 为 0.94（95% CI，0.89-0.97）。内部一致性分析显示 Cronbach alpha 为 0.93。测量标准误差 (SEM) 为 8.5 个刻度点（基于 90% CI），最小可检测变化 (MDC) 为 12.1 个刻度点（基于 90% CI）。改善的最小临床重要差异 (MCID) 为 11.4 分。 PSS 与CSS 和ASES 之间的皮尔逊积矩相关系数分别为0.85 和0.87。反应性分析显示，效应大小为 1.01，标准化反应平均值为 1.27。结论：本研究表明，PSS 是报告各种肩部疾病患者预后的可靠且有效的衡量标准。
Study Design: Psychometric evaluation of a cross-sectional survey.Objectives: The purpose of this study was to examine the psychometric properties of reliability and validity of the Penn Shoulder Score (PSS).Background: Shoulder outcome measures are used to assess patient self-report levels of pain, satisfaction, and function. The PSS is a 100-point shoulder-specific self-report questionnaire consisting of 3 subscales of pain, satisfaction, and function. This scale has been utilized in the literature. However, the measurement properties of reliability and validity, including responsiveness, of the PSS subscales and overall scale need to be established.Methods and Measures: Patients (n = 40) with shoulder disorders undergoing a course of outpatient physical therapy completed the PSS at initial visit and again within 72 hours to assess test-retest reliability. The Constant Shoulder Score (CSS) and the American Shoulder and Elbow Surgeons Shoulder Score (ASES) were also completed at the initial visit and compared to the PSS to assess convergent construct validity. A separate cohort of patients (n = 109) completed the PSS at initial visit and 4 weeks later. These scores were used to assess internal consistency and responsiveness.Results: Reliability analysis revealed a test-retest IC2,1 of 0.94 (95% CI, 0.89-0.97). Internal consistency analysis revealed a Cronbach alpha of 0.93. The standard error of measurement (SEM) was 8.5 scale points (based on a 90% CI) and the minimal detectable change (MDC) was 12.1 scale points (based on a 90% CI). The minimal clinically important difference (MCID) for improvement was 11.4 points. Pearson product moment correlation coefficients between the PSS and the CSS and ASES were 0.85 and 0.87, respectively. Responsiveness analysis revealed an effect size of 1.01 and a standardized response mean of 1.27.Conclusions: This study has demonstrated that the PSS is a reliable and valid measure for reporting outcome of patients with various shoulder disorders.
