Abstract

Background: Perceived social support represents a key factor influencing both mental and physical health, yet brief Arabic measures are scarce.

Objectives: To assess the psychometric properties of the Arabic version of the abbreviated 6-item Medical Outcomes Study-Social Support Survey (MOS-SSS-6) among Saudi adults.

Methods: An online questionnaire was distributed via social media platforms to assess perceived social support, psychological distress, quality of life (QoL), and coping. Cronbach's alpha (α), McDonald's omega (ω), and corrected item-total correlations were used to evaluate the scale's reliability. Exploratory factor analysis (EFA) was conducted on 50% of the sample, using maximum likelihood with varimax rotation to identify factor structure. Confirmatory factor analysis (CFA) validated the model in the other 50%, with fit assessed through RMSEA, SRMR, CFI, TLI, and other indices. Concurrent validity was evaluated through Pearson's correlations with relevant psychological measures.

Results: A total of 1028 Saudi adults completed the questionnaire. Suitability of the data for EFA was supported by a strong KMO value (0.83) and significant Bartlett's test of sphericity (P < 0.001). Parallel analysis indicated that a three-factor solution was optimal, explaining 80% of the variance. CFA confirmed this model with excellent fit indices (CFI = 0.99, TLI = 0.98, RMSEA = 0.07, SRMR = 0.02, GFI = 0.99, AGFI = 0.95). Negative relationships with depression (r = -0.24, P < 0.01) and anxiety (r = -0.17, P < 0.01), and a positive correlation with QoL (r = 0.37, P < 0.01) and adaptive coping strategies provided evidence for concurrent validity. The Arabic MOS-SSS-6 exhibited high internal consistency (α = 0.90, ω = 0.90).

Conclusions: The Arabic MOS-SSS-6 is a reliable and valid instrument for measuring perceived social support among Saudi adults, demonstrating significant correlations with psychological variables relevant for psychological assessments and interventions.

沙特阿拉伯成人医疗结果研究-社会支持调查-6的探索性和验证性因素分析

背景：感知到的社会支持是影响身心健康的一个关键因素，但阿拉伯很少有简短的措施。目的：评估阿拉伯语版的简短6项医疗结果研究-社会支持调查（MOS-SSS-6）在沙特成年人中的心理测量特性。方法：通过社交媒体平台发放在线问卷，评估患者的感知社会支持、心理困扰、生活质量（QoL）和应对能力。采用Cronbach’s alpha （α）、McDonald’s omega （ω）和校正后的项目-总量相关性来评估量表的信度。对50%的样本进行探索性因子分析（EFA），使用最大似然和最大旋转来确定因子结构。验证性因子分析（CFA）验证了另外50%的模型，并通过RMSEA、SRMR、CFI、TLI等指标评估了模型的拟合性。通过与相关心理测量的Pearson相关来评估并发效度。结果：共有1028名沙特成年人完成了问卷调查。较强的KMO值（0.83）和显著的Bartlett球度检验（P < 0.001）支持EFA数据的适用性。并行分析表明，三因素解决方案是最优的，解释80%的方差。CFA验证了该模型的拟合指数（CFI = 0.99, TLI = 0.98, RMSEA = 0.07, SRMR = 0.02, GFI = 0.99, AGFI = 0.95）。与抑郁（r = -0.24, P < 0.01）和焦虑（r = -0.17, P < 0.01）呈负相关，与生活质量（r = 0.37, P < 0.01）和适应性应对策略呈正相关，为并发效度提供了证据。阿拉伯MOS-SSS-6具有较高的内部一致性（α = 0.90, ω = 0.90）。结论：阿拉伯语MOS-SSS-6是一种可靠有效的测量沙特成年人感知社会支持的工具，显示出与心理评估和干预相关的心理变量显著相关。
