BACKGROUND
The Shoulder and Pain Disability Index (SPADI) is a widely used outcome measure. The aim of this study is to explore the reliability and validity of SPADI in a sample of patients with idiopathic frozen shoulder.
METHODS
The SPADI was administered to 124 patients with idiopathic frozen shoulder. A sub-group of 29 patients were retested after 7 days. SPADI scores were correlated with other outcome measures (i.e., Disabilities of the Arm, Shoulder and Hand Questionnaire - DASH; Numerical Pain Rating Scale-NPRS; and 36-item Short Form Health Survey-SF-36) to examine construct validity. Structural validity was assessed by a Two-Factors Confirmatory Factor Analysis (CFA). Internal consistency, test-retest reliability, and measurement error were also analyzed.
RESULTS
The construct validity was satisfactory as seven out of eight of the expected correlations formulated (≥ 75%) for the subscales were satisfied. The CFA showed good values of all indicators for both Pain and Disability subscales (Comparative Fit Index = 0.999; Tucker-Lewis Index = 0.997; Root Mean Square Error of Approximation = 0.030). Internal consistency was good for pain (α = 0.859) and disability (α = 0.895) subscales. High test-retest reliability (Intraclass correlation coefficient [ICC]) was found for pain (ICC = 0.989 [95% Confidence Interval (CI = 0.975-0.995]) and disability (ICC = 0.990 [95% CI = 0.988-0.998]). Standard Error of Measurement values of 2.27 and 2.32 and Minimal Detectable Change values of 6.27 and 6.25 were calculated for pain and disability subscales, respectively.
CONCLUSION
The SPADI demonstrated satisfactory reliability and validity properties in a sample of patients with idiopathic frozen shoulder.
背景
肩痛和上肢功能障碍指数（SPADI）是一种广泛使用的结果测量工具。本研究的目的是探讨 SPADI 在特发性冻结肩患者中的可靠性和有效性。
方法
对 124 例特发性冻结肩患者进行 SPADI 评估。其中 29 例患者在 7 天后进行了复测。将 SPADI 评分与其他结果测量指标（即手臂、肩和手残疾问卷-DASH；数字疼痛评分量表-NPRS；36 项简短健康调查-SF-36）进行相关性分析，以检验结构有效性。通过双因素验证性因子分析（CFA）评估结构有效性。还分析了内部一致性、重测信度和测量误差。
结果
结构有效性令人满意，因为 7 个（≥75%）预期的子量表相关性得到了满足。CFA 显示疼痛和残疾子量表的所有指标值均较好（比较拟合指数=0.999；塔克-刘易斯指数=0.997；均方根误差近似值=0.030）。疼痛（α=0.859）和残疾（α=0.895）子量表的内部一致性较好。疼痛（ICC=0.989 [95%置信区间（CI）=0.975-0.995]）和残疾（ICC=0.990 [95% CI=0.988-0.998]）的重测信度高。疼痛和残疾子量表的测量误差值分别为 2.27 和 2.32，最小可检测变化值分别为 6.27 和 6.25。
结论
SPADI 在特发性冻结肩患者中具有较好的可靠性和有效性。
