AI Insight
This study successfully translated and validated the Generalized Anxiety Disorder-7 (GAD-7) screening tool into Tibetan for use in high-altitude Tibetan communities. Testing with 583 adults revealed the Tibetan GAD-7 has acceptable reliability and a two-factor structure that better fits the data than the original one-factor model. The tool identified higher anxiety levels among females, urban residents, and lower-income individuals in these populations.
Why it matters
This validation provides the first culturally adapted anxiety screening instrument for Tibetan-speaking populations living at high altitudes, who have limited access to mental health resources. The tool enables early detection of anxiety disorders in an underserved community, potentially improving mental health outcomes through timely intervention.
Understand the Science
ObjectiveTo translate the Generalized Anxiety Disorder-7 (GAD-7) scale into Tibetan and evaluate its psychometric properties for assessing anxiety symptoms of the Tibetan communities living in high altitudes.MethodologyFollowing a standardized translation and cross-cultural adaptation procedure, the Tibetan GAD-7 was administered to 583 adults recruited via convenience sampling in Tibetan areas. Its reliability was assessed using Cronbach’s alpha and item-total correlations. Construct validity was examined using Exploratory Factor Analysis (EFA, n = 290) and Confirmatory Factor Analysis (CFA, n = 293) by randomly splitting the sample into two halves. Group differences in GAD-7 scores across sociodemographic variables were analyzed using t-tests and Analysis of Variance (ANOVA).ResultsThe Tibetan GAD-7 demonstrated acceptable internal consistency (Cronbach’s α = 0.70). EFA suggested a two-factor structure, which was further supported by CFA, showing a significantly better model fit (CFI = 0.90, TLI = 0.82, RMSEA = 0.09) than a one-factor model (CFI = 0.71, TLI = 0.57, RMSEA = 0.14). Significant group differences were also found, with females, urban residents, and individuals with lower household income reporting higher anxiety scores.ConclusionThe Tibetan version of the GAD-7 shows acceptable reliability and validity as a screening tool for generalized anxiety symptoms in high-altitude Tibetan populations. Its use can facilitate early identification of anxiety in this underserved, culturally distinct community with limited mental health resources.
