Given the excessive length and inconsistent validity of the existing long stroke-specific quality of life (SS-QOL) scales, there is a need to validate a shorter measuring tool. The aim of this study was to validate the Arabic version of the short 12-item SS-QOL (SS-QOL-12-AR) and examine its validity measures and psychometric properties. Additionally, the study aimed to assess the QOL after stroke and identify the sociodemographic and clinical factors that influence it in Lebanon.
A cross-sectional study was conducted. The SS-QOL-12-AR structure was validated, and its reliability and internal consistency were assessed. The scale's specificity and sensitivity were evaluated and then compared with those of other SS-QOL scales. The correlation between each item and the overall scale were examined, and its convergent validity was evaluated.
A total of 172 stroke survivors were included. The SS-QOL-12-AR structure was validated with a solution of two factors, with a Kaiser-Meyer-Olkin measure of sampling adequacy of 0.850 and a significant Bartlett's test of sphericity ( < 0.001). The Cronbach's alpha of the scale was 0.917. According to ROC curve analysis, the optimal cut-off point for distinguishing between lower and better QOL was 32.50. At this cut-off, the sensitivity and specificity were 70.0% and 71.2%, respectively. The area under the curve was 0.779 (95% CI 0.704-0.855, < 0.001). The SS-QOL-12-AR demonstrated a strong and highly significant correlation with existing versions of the SS-QOL, confirming its convergent validity. 61.6% of stroke survivors had a lower QOL, which was significantly associated with poor stroke prognosis, increased physical dependence, current smoking, and alcohol abstinence.
The SS-QOL-12-AR exhibits strong validity and reliability, demonstrating excellent psychometric properties. The scale holds potential for application in clinical practice and research settings, enabling the measurement of stroke-related consequences and evaluation of management outcomes.
鉴于现有的长版卒中特异性生活质量（SS-QOL）量表过长且效度不一致，需要验证一种更短的测量工具。本研究的目的是验证阿拉伯语版的简短12项SS-QOL（SS-QOL-12-AR），并检验其效度指标和心理测量特性。此外，该研究旨在评估黎巴嫩卒中后的生活质量，并确定影响生活质量的社会人口统计学和临床因素。
进行了一项横断面研究。对SS-QOL-12-AR的结构进行了验证，并评估了其信度和内部一致性。对该量表的特异性和敏感性进行了评估，然后与其他SS-QOL量表进行了比较。检验了每个项目与总量表之间的相关性，并评估了其收敛效度。
共纳入172名卒中幸存者。SS-QOL-12-AR的结构通过两个因素的解决方案得到验证，Kaiser-Meyer-Olkin抽样适当性度量为0.850，Bartlett球形检验具有显著性（<0.001）。该量表的Cronbach's alpha系数为0.917。根据ROC曲线分析，区分较低和较好生活质量的最佳临界点为32.50。在此临界点，敏感性和特异性分别为70.0%和71.2%。曲线下面积为0.779（95%CI 0.704-0.855，<0.001）。SS-QOL-12-AR与现有版本的SS-QOL表现出强烈且高度显著的相关性，证实了其收敛效度。61.6%的卒中幸存者生活质量较低，这与卒中预后不良、身体依赖性增加、当前吸烟和戒酒显著相关。
SS-QOL-12-AR具有很强的效度和信度，显示出优异的心理测量特性。该量表在临床实践和研究环境中具有应用潜力，能够测量与卒中相关的后果并评估管理结果。
