Abstract

This research aimed to adapt the Positivity Scale (PS) to the Brazilian context, gathering evidence of validity and reliability. Two studies were performed. Study 1 was composed of 200 people from Paraíba, with a mean age of 23.4 years old (SD = 4.53), who answered the PS and demographic questions. Results pointed to a one-factor solution in this scale, which presented satisfactory reliability (α = .85). Study 2 gathered 290 undergraduate students with a mean age of 23.9 years old (SD = 7.60), who answered the PS, the Satisfaction with Life Scale, the Subjective Vitality Scale and demographic questions. Confirmatory factor analyses (ML and ADF estimators) corroborated the one-factor structure, which presented an acceptable reliability (CR = .65). Furthermore, its convergent validity was confirmed based on the average variance extracted (AVE = .60) and on its correlations with satisfaction with life and vitality (p < .001). In conclusion, this measure has been shown to be psychometrically adequate for use in Brazil.
