BORSA, Juliane Callegaro et al. Psychometric properties of the positivity scale - Brazilian version. Psicol. Reflex. Crit. [online]. 2015, vol.28, n.1, pp.61-67. ISSN 0102-7972.

This study presents the psychometric properties of the Brazilian version of the Positivity Scale (P-Scale). Participants were 730 subjects (65% women), aged from 17 to 70 years old (M = 31.0 years; SD = 11.43), from 21 Brazilian states. The sample was randomly split in two halves to cross-validate the results. With the first half of the sample (n1 = 365), an exploratory factor analysis (EFA) was conducted. With the second half of the sample (n2 = 365), a confirmatory factor analysis (CFA) assessed the fit of the exploratory model. Convergent validity and group differences were also evaluated. The EFA and CFA presented a one-dimensional structure for the P-Scale. Moderate correlations were found between the P-Scale and mental-health, subjective happiness and life-satisfaction. The levels of positivity presented a low positive correlation with age, educational level and financial income. Slightly significant effects were found for occupational status and marital status. Positivity appears to be more closely related to personal dispositions than to sociodemographic aspects. Our results suggest that the P-Scale is a reliable measure with which to evaluate the levels of positivity in Brazil.
