Perceived stress and its epidemiological and behavioral correlates in an Urban Area of Delhi, India: A community-based cross-sectional study

Background: Increasing stress has been recognized as a major public health problem in the developing world accelerated by an ongoing demographic, economic, and sociocultural transition. Our study objectives were to validate a Hindi version of the 10-item Perceived Stress Scale (PSS-10) and to also assess the extent of perceived stress and its correlates among an adult population in an urban area of Delhi. Methodology: A community-based cross-sectional study was conducted in an urban resettlement colony of Delhi among 480 adult subjects aged 25--65 years, during the period from January to December 2015. The PSS-10 was translated into Hindi and validated in the study population. Data was analyzed using IBM SPSS Version 25. Results: A total of 243 (50.6%) men and 237 (49.4%) women were enrolled. The scale had an acceptable level of internal consistency (Cronbach's alpha = 0.731). A principal component analysis was run on the PSS-10 data, based on which a three-component structure was accepted, which explained 61% of the total variance. The mean PSS score was 19.25 (SD = 4.50) years. Perceived stress was highest in the 35--50 age group. On multivariate analysis, low socioeconomic status and a white-collar occupation were found to be associated with increased perceived stress (P < 0.001)Conclusion: A high burden of perceived stress exists in residents of a low-income urban population in India.
