The Personal Well-being Index-school children (PWI-SC; Cummins and Lau 2005) measures well-being of adolescents. The study aimed at validating psychometric properties for the English and the Hindi translated version of PWI-SC in Indian context. Data from 1,301 students, aged 13–18 years (mean age = 15.40 years, SD = 1.33) was collected. The English and Hindi version confirmed one-factor solution of the PWI-SC. The convergent validity was supported through positive correlations with Flourishing Scale (FS; Diener et al. 2010) and Brief Multidimensional Students Life Satisfaction Scale (BMSLSS; Huebner et al. 2004). The effect of demographic variables on different domains of PWI-SC indicated that adolescents who resided in rural areas and those who attended private school possessed a significantly higher score on PWI-SC. Well-being declined as age increased from early adolescent to middle adolescence to late adolescence. The results of this study are in agreement with the previous literature.
