Factor Structure of the Telugu Version of the COVID-19 Pandemic-Related Perceived Stress Scale (PSS-10-C) Administered on Grassroots Frontline Health Care Workers of Rural Telangana

BACKGROUND: During the COVID-19 pandemic, perceived stress is an important determinant of mental health problems, especially in health care workers (HCW). By and large, regional language tools to assess perceived stress in the context of the pandemic have not been validated in India. We aim to explore the factor structure of the Telugu translated version of the COVID-19 pandemic-related Perceived Stress Scale (PSS-10-C) administered on grassroots frontline HCW of rural Telangana, India. METHODS: Data relating to 311 grassroots frontline HCW consisting of accredited social health activists (ASHA), multipurpose health workers (MPHW), and auxiliary nurse and midwives (ANMs) working in rural primary health centers (PHC) in five districts of Telangana were analyzed. An exploratory factor analysis was conducted to identify latent factors. Convergent validity was assessed by computing Pearson product-moment correlations between the scores of PSS-10-C and Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) scales. RESULTS: The principal component analysis showed that the 10 items of the scale were significantly loaded by two latent factors with eigen values of 2.792 and 2.009, respectively. Factor solution showed that six and four items correlated with each of the two factors, respectively. Significant correlations between PSS-10-C, GAD-7, and PHQ-9 scores showed convergent validity. The two factors may represent substantive factors “perceived self-efficacy” and “perceived helplessness.” There may be an influence of the reverse-coded method on the factor solution. CONCLUSION: The Telugu translated version of PSS-10-C holds fair-to-good psychometric properties.
