• Personal Wellbeing Index
• subjective well-being
• adolescents and social indicators
• Personal Wellbeing Scale

The psychometric properties of the Personal Wellbeing Index are analyzed on a Spanish and Portuguese adolescent sample. We test the reliability of the scale using Cronbach's alpha. And complementarily we analyze the item-total correlations in the different wellbeing domains included. We execute an exploratory factor analysis (principal components) and a multigroup Confirmatory Factor Analysis (CFA). The results show that Cronbach's alpha is 0.79 for the Chilean version and in the Brazilian version is 0.78. confirming adequate levels of reliability found in previous studies. Correlations between fields of well-being shows values ranging between 0.224 and 0.496 for Chile and from 0.24 to 0.46 for Brazil. The results are similar to those obtained in other countries. The monofactorial structure of the scale is confirmed. also the adjustment to the scale structure to the data of the two samples and the comparability of means of global indices. The results suggest the existence of other well-being domains that had not been considered in the original proposal of the scale.
