Prioritize positivity in Italians: a validation and measurement invariance study of an italian version of the prioritizing positivity scale

Prioritizing positivity is effective in enhancing positive emotional experiences in everyday life. While a measure of prioritizing positivity is imperative for positive psychology interventions, no scale has been developed to measure this construct for Italian speakers. The current study developed and examined the psychometric properties of an Italian version of the Prioritizing Positivity Scale (I-PPS). Italian participants (N = 501) completed self-report measures of the I-PPS, broad personality, related psychological constructs, and indicators of well-being. Results showed strong evidence for a unidimensional model with factor loadings ranging from 0.67 to 0.82. Correlations in the expected directions were found between the I-PPS and broad personality traits, related psychological constructs, and well-being. Gender and language measurement invariance of the I-PSS revealed strict invariance between genders and metric invariance between the English (N = 642) and Italian versions. Overall, this study provides preliminary evidence that the I-PPS has adequate psychometric properties. As such, the scale could be used in future studies to advance theories, design experiments, and measure the efficacy of positive psychology interventions.
