The Shoulder Pain and Disability Index (SPADI) is a valid and reliable questionnaire used in shoulder disorders. The purpose of this study was to test the convergent validity and the reliability of the SPADI.
A total of 101 female patients with shoulder pain were enrolled in the study. The SPADI and the Health Assessment Questionnaire (HAQ) were completed by all the participants. Pain was measured using the Visual Analogue Scale (VAS) during the active range of motion. Reliability was measured by internal consistency and test-retest reliability. Internal consistency was determined by calculating Cronbach's alpha value. Convergent validity was examined by correlating the SPADI questionnaire with the VAS and HAQ scales.
Cronbach's alpha value for the SPADI was found to be 0.94. Test-retest reliability of the SPADI was found to be high (0.92). The correlation coefficient for convergent validity of the SPADI was 0.65 and 0.67 for the VAS and HAQ overall scores, respectively.
The results of the present study suggest that the SPADI is a valid and reliable instrument to assess shoulder pain in Turkish female patients.
肩痛和残疾指数（SPADI）是一种用于肩部疾病的有效且可靠的问卷。本研究的目的是测试 SPADI 的聚合效度和可靠性。
共有 101 名患有肩部疼痛的女性患者入组本研究。所有参与者均完成了 SPADI 和健康评估问卷（HAQ）。在主动运动范围内，使用视觉模拟量表（VAS）测量疼痛。通过内部一致性和重测信度来衡量可靠性。通过计算 Cronbach's alpha 值来确定内部一致性。通过将 SPADI 问卷与 VAS 和 HAQ 量表相关联来检查聚合效度。
SPADI 的 Cronbach's alpha 值为 0.94。SPADI 的重测信度很高（0.92）。SPADI 的聚合效度的相关系数为 0.65，与 VAS 和 HAQ 总分的相关系数分别为 0.67。
本研究结果表明，SPADI 是一种有效且可靠的工具，可用于评估土耳其女性患者的肩部疼痛。
