Disabil Rehabil. 2025 Apr;47(7):1854-1860. doi: 10.1080/09638288.2024.2387688. Epub 2024 Aug 20.
To investigate the test-retest reliability and construct validity of the Brief Pain Inventory-Short Form (BPI-SF) in individuals with rotator cuff-related shoulder pain (RCRSP).
Sixty-one participants with RCRSP completed the BPI-SF twice with an interval of two to seven days and Shoulder Pain and Disability Index (SPADI) at the initial visit. The BPI-SF pain severity subscale, pain interference subscale, and stand-alone pain severity items were analysed using intraclass correlation coefficients (ICCs) and minimal detectable change at the 95% confidence interval (MDC). The construct validity of BPI-SF was assessed against SPADI using Pearson's correlation.
The BPI-SF pain severity and pain interference subscales presented moderate test-retest reliability (ICC = 0.73, 0.53) and MDC were 2.05 and 2.36. All stand-alone BPI-SF pain severity items presented a moderate reliability (ICC = 0.62, 0.70). BPI-SF interference items presented poor to moderate reliability (ICC = 0.39, 0.68). The correlation coefficients between the BPI-SF and SPADI subscales or total scores were large ( = 0.61, 0.75).
BPI-SF pain severity and pain interference subscales have a moderate reliability in individuals with RCRSP. BPI-SF pain severity and interference subscales showed high construct validity in individuals with RCRSP. MDC values are useful metrics for interpreting a true change in BPI-SF scores following interventions in individuals with RCRSP.
探讨简式疼痛问卷-简短形式（BPI-SF）在肩袖相关肩部疼痛（RCRSP）患者中的重测信度和结构效度。
61例RCRSP患者在初次就诊时完成BPI-SF问卷，间隔2至7天后再次完成该问卷，并完成肩部疼痛和功能障碍指数（SPADI）评估。使用组内相关系数（ICC）和95%置信区间的最小可检测变化（MDC）分析BPI-SF疼痛严重程度分量表、疼痛干扰分量表及独立的疼痛严重程度项目。采用Pearson相关性分析评估BPI-SF与SPADI的结构效度。
BPI-SF疼痛严重程度和疼痛干扰分量表呈现出中度重测信度（ICC分别为0.73和0.53），MDC分别为2.05和2.36。所有独立的BPI-SF疼痛严重程度项目呈现出中度信度（ICC分别为0.62和0.70）。BPI-SF干扰项目呈现出从差到中度的信度（ICC分别为0.39和0.68）。BPI-SF与SPADI分量表或总分之间的相关系数较大（分别为0.61和0.75）。
BPI-SF疼痛严重程度和疼痛干扰分量表在RCRSP患者中具有中度信度。BPI-SF疼痛严重程度和干扰分量表在RCRSP患者中显示出较高的结构效度。MDC值是解释RCRSP患者干预后BPI-SF评分真实变化的有用指标。
