The unpredictability of the COVID-19 pandemic can induce psychological distress in individuals. We investigated perceived stressors, prevalence of psychological distress and suicidal ideation, and predictors of psychological distress among adults during the COVID-19 pandemic in Eswatini. This study was a cross-sectional, population-based household telephone survey of 993 conveniently sampled adults (18+ years) from all the four administrative regions of Eswatini. Data were collected between 9 June and 18 July 2020 during the first wave of the COVID-19 pandemic, when the country was under a partial lockdown. COVID-19-related psychological distress was assessed using the Kessler 6-item Psychological Distress Scale (K6). We performed weighted modified Poisson regression analyses to identify significant predictors of moderate/severe psychological distress (K6 scores: ≥5). The weighted prevalences of moderate (K6 scores: 5–12) and severe psychological distress (K6 scores: ≥13) were 41.7% and 5.4%, respectively. Participants reported several perceived COVID-19-related stressors, including worries and fears of the contagion-specific death, serious need for food and money, and concerns about loss of income or business. The weighted prevalence of suicidal ideation was 1.5%. Statistically significant predictors of increased risk for moderate/severe psychological distress included living in the Hhohho and Manzini regions; feeling not well informed about COVID-19; feeling lonely; having received COVID-19 food or financial relief from the government; feeling burdened by the lockdown; being married; and being youth (18–24 years). The results call for the government to urgently augment the provision of mental health services during the pandemic. Mental health practitioners and programs may use several stressors and risk factors identified in this study to inform interventions and government policies aimed at reducing psychological distress induced by the pandemic.

Objective: This study (1) describes the distribution of Kessler Psychological Distress Scale (K6) scores in an epidemiological sample of youth, (2) reports its item correlations and internal consistency reliability, (3) tests for measurement invariance by age (youth vs. adults) and sex, and (4) examines its predictive power for past-year psychiatric disorders. Method: Youth aged 15 to 19 years ( n = 2010) and adults aged 20 to 64 years ( n = 2010) from the Canadian Community Health Survey–Mental Health who completed the K6 were included. Past-year psychiatric disorders were measured using the World Health Organization Composite International Diagnostic Interview 3.0 (WHO-CIDI). Polychoric correlation matrices and ordinal reliability coefficients were calculated to assess internal consistency of the K6, and confirmatory factor analysis was used to test for measurement invariance. Area under the curves (AUCs) were computed to determine the extent to which the K6 predicted a positive screen on the WHO-CIDI. Results: K6 scores showed a J-shaped distribution, with >50% of youth having scores ≤3. Item and total scores were higher for females versus males. Item correlations were robust (0.31-0.78) and internal consistency was high (α = 0.86). Full measurement invariance was demonstrated between youth and adults, as well as between male and female youth. The K6 was a strong predictor of major depressive episode (AUC = 0.848), generalized anxiety disorder (AUC = 0.847), and bipolar disorder (AUC = 0.853). Conclusions: The K6 is a valid and reliable measure of psychological distress among youth. Its brevity and robust predictive power for psychiatric disorder confirm its utility in clinical and community settings to identify youth needing comprehensive psychiatric assessment.
