Subjective wellbeing in the Indian general population: a validation study of the Personal Wellbeing Index

The Personal Wellbeing Index (PWI) is a commonly used measure of life satisfaction that reflects a person's level of subjective wellbeing (SWB). The present study aimed to establish the validity and reliability of the PWI in a large sample of Indian adults and describe their SWB.

2004 Indian adults completed a cross-sectional online survey, which was presented in English and included the PWI and demographic questions. The sample was split to assess the psychometric properties of the 7-item (n = 981) and 8-item (n = 937) versions of the PWI.

Both the 7- and 8-item versions of the PWI demonstrated adequate internal consistency (α = .89 and .88, respectively). The global means for both versions of the PWI (7-item = 74.43, 8-item = 73.82) were within the normative range for Western countries. Achieving in life had the lowest domain scores for both the 7-item (M = 70.51) and 8-item (M = 68.37) versions; the spirituality or religion domain had the highest domain score in the 8-item version (M = 78.84).

The findings suggest that both the 7- and 8-item versions of the PWI are valid and reliable measures of life satisfaction for use in India. The global mean scores for both versions of the PWI were within the normative range for Western countries. In this study, Indians reported high levels of satisfaction with their spirituality or religion, suggesting this domain may be an important contributor of SWB; however, more research is needed to determine this.
