广泛性焦虑症（GAD）在撒哈拉以南非洲的艾滋病毒/艾滋病感染者中调查不足。这部分是由于缺乏文化上适当的性别与焦虑的测量方法，这些方法在心理测量上是可靠的。本研究旨在评估斯瓦希里语版本的7项GAD问卷（GAD-7）在成人艾滋病毒感染者中的信度、因子结构和效度。描述性横断面研究。连续招募了450名在肯尼亚沿海Kilifi县的艾滋病毒专门诊所接受全面护理的成年人。斯瓦希里语版本的GAD-7，患者健康问卷（PHQ-9）和12项艾滋病毒的耻辱规模一起管理的心理和健康相关的特征的措施。采用Cronbach’s alpha（α）、组内相关系数（ICC）、验证性因素分析（CFA）、Pearson’s相关和协方差分析（ANCOVA）分别对斯瓦希里语GAD-7的内部一致性、重测信度、因子结构、聚合效度和判别效度进行了检验。斯瓦希里语GAD-7的内部一致性良好，α = 0.82（95%CI 0.78，0.85）。其重测信度（间隔2周）可接受，ICC = 0.70（95% CI 0.55，0.81）。单因素解决方案的验证性分析表明与假设结构非常吻合（RMSEA = 0.00 [95%置信区间0.00，0.05]，CFI = 1.00，TLI = 1.00）。多组CFA证实了斯瓦希里语GAD-7单因素结构的性别和年龄的因子不变性。斯瓦希里语版GAD-7的得分与PHQ-9（r = 0.73; p < 0.001）和HIV耻辱量表（r = 0.36; p < 0.001）的得分显著相关，表明具有良好的收敛效度。一线抗逆转录病毒治疗的受试者与二线治疗的受试者之间观察到统计学显著差异（F [1，441] = 5.55，p = 0.02），表明斯瓦希里语GAD-7具有良好的判别效度。GAD-7斯瓦希里语版本保留了其原始的一维潜在结构，在来自肯尼亚基利菲的成年艾滋病毒感染者中具有良好的心理测量特性。它可用于在类似的研究环境中识别GAD的症状。然而，自信地确定那些需要心理健康治疗或转诊服务的艾滋病毒初级保健诊所，需要更多的研究斯瓦希里语GAD-7的有效性，特别是其判别效度和诊断准确性在不同的截止分数。
Generalized Anxiety Disorder (GAD) is under-investigated in people living with HIV/AIDS from sub-Saharan Africa. In part, this is due to paucity of culturally appropriate measures for GAD which are psychometrically robust. This study aimed to evaluate the reliability, factorial structure, and validity of Swahili version of the 7-item GAD questionnaire (GAD-7) among adults living with HIV. Descriptive cross-sectional study. 450 adults receiving comprehensive care from an HIV specialized clinic in Kilifi County, coastal Kenya, were consecutively recruited. Swahili versions of GAD-7, Patient Health Questionnaire (PHQ-9) and a 12-item HIV stigma scale were administered alongside measures of psychosocial and health-related characteristics. Internal consistency, test–retest reliability, factorial structure, convergent validity, and discriminant validity of Swahili GAD-7 were examined using Cronbach’s alpha (α), intra-class correlation coefficient (ICC), Confirmatory Factor Analysis (CFA), Pearson’s correlation, and analysis of covariance (ANCOVA), respectively. Internal consistency of Swahili GAD-7 was good, α = 0.82 (95% CI 0.78, 0.85). Its test–retest reliability (2 weeks apart) was acceptable, ICC = 0.70 (95% CI 0.55, 0.81). A confirmatory analysis of a one-factor solution indicated an excellent fit to the hypothesized structure (RMSEA = 0.00 [95% confidence interval 0.00, 0.05], CFI = 1.00, TLI = 1.00). Multi-group CFA substantiated factorial invariance for sex and age for the one-factor structure of Swahili GAD-7. Scores of GAD-7, Swahili version, significantly correlated with those of PHQ-9 (r = 0.73; p < 0.001) and the HIV stigma scale (r = 0.36; p < 0.001) suggesting good convergent validity. Statistically significant differences were observed between participants on first-line antiretroviral therapy compared to those on second-line treatment (F [1, 441] = 5.55, p = 0.02) indicative of good discriminant validity of Swahili GAD-7. GAD-7 Swahili version retained its original unidimensional latent structure with good psychometric properties among adults living with HIV from Kilifi, Kenya. It can be used to identify symptoms of GAD in similar research settings. However, to confidently identify those in need of mental health treatment or referral services in HIV primary care clinics, more research on the validity of Swahili GAD-7 is needed especially its discriminant validity and diagnostic accuracy at different cut-off scores.
