Validation of a performance scale.
The purpose of this study is to investigate adaptation, validity, and reliability of the Turkish version of the Back Performance Scale (BPS).
Low back pain affects people of all ages and causes pain, disability, and psychosocial problems. BPS is a condition-specific performance measure of activity limitation in patients with low back pain. The purpose of this study is to investigate the cross-cultural adaptation, validity, and reliability of the Turkish version of the BPS.
The study included 180 patients with low back pain. For the reliability assessment of the scale, test-retest, and internal consistency analyses were performed. The results of the test-retest analysis were analyzed by Intraclass Correlation Coefficient (ICC) method. For the internal consistency, Cronbach Alpha value was calculated and to construct validity, total points of the BPS were compared with the total points of Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) using Pearson correlation coefficient analysis.
BPS was found to have high internal consistency (Cronbach alpha value 0.827). Test-retest results were found highly correlated (range from 0.723 to 0.899). Factor analysis indicated that the scale had one factor. BPS is well correlated with RMDQ and ODI (Pearson correlation coefficient with RMDQ 0.576 and with ODI 0.603).
The Turkish version of BPS is valid and reliable.
性能量表的验证。
本研究旨在探讨土耳其版背部绩效量表（BPS）的适用性、有效性和可靠性。
腰痛影响各个年龄段的人群，导致疼痛、残疾和心理社会问题。BPS 是一种针对腰痛患者活动受限的特定于病情的绩效测量方法。本研究旨在探讨土耳其版 BPS 的跨文化适应性、有效性和可靠性。
该研究纳入了 180 名腰痛患者。为了评估量表的可靠性，进行了重测信度和内部一致性分析。重测分析的结果通过组内相关系数（ICC）法进行分析。为了评估内部一致性，计算了 Cronbach Alpha 值，并通过 Pearson 相关系数分析比较了 BPS 的总分与 Roland Morris 残疾问卷（RMDQ）和 Oswestry 残疾指数（ODI）的总分，以构建效度。
BPS 具有较高的内部一致性（Cronbach alpha 值为 0.827）。重测结果高度相关（范围为 0.723 至 0.899）。因子分析表明该量表具有一个因子。BPS 与 RMDQ 和 ODI 具有良好的相关性（与 RMDQ 的 Pearson 相关系数为 0.576，与 ODI 的 Pearson 相关系数为 0.603）。
土耳其版 BPS 具有良好的有效性和可靠性。
