Psychological well-being among Saudi adults during the context of COVID-19 lockdown: a psychometric analysis of the 12-item General Health Questionnaire

BACKGROUND: Most communities' mental health and perceptions of psychological well-being are known to be profoundly disrupted by large-scale pandemics. Despite the wide range of available screening measures, few reliable and valid screening measures exist for assessing overall psychological well-being in nonclinical populations during a health emergency situation such as the COVID-19 outbreak. OBJECTIVE: This study aims to conduct a psychometric analysis of Goldberg’s 12-item General Health Questionnaire (GHQ-12) to validate its use among a sample of Saudi adults during the COVID-19 lockdown using reliability and factor analyses. METHODS: A total of 473 individuals (aged 18 years and over) were recruited from the general Saudi population living in the Makkah (Western) Province of Saudi Arabia to complete the virtual format of the Arabic GHQ-12 (Ar-GHQ-12). In addition to a descriptive statistics measurement and reliability analysis, confirmatory factor analyses (CFA) were performed to examine the unidimensionality and validity of the Ar-GHQ-12. RESULTS: In line with previous works from several cultures, the Ar-GHQ-12 with two-factor solution considered to be the best-fitting model because it fits the data better than the one-factor (unidimensional) model did, and adequate reliability indices were achieved for each factor (.83 for factor 1 and .65 for factor 2). DISCUSSION: The Ar-GHQ-12 was determined to be suitable for assessing the overall psychological well-being of the general population in Saudi Arabia in emergency contexts and may be applied among Saudis and other Arabic-speaking populations in research and primary care settings.
