“…Overall, the P Scale has been found to have robust psychometric properties as indicated by its good reliability coefficients (e.g., Caprara et al, 2012), its measurement invariance across gender and countries (e.g., Caprara et al, 2012; Heikamp et al, 2014), and its expected associations with theoretically relevant constructs such as positive and negative affect, depression, and personality traits (e.g., Caprara et al, 2012; Borsa et al, 2015; Tian et al, 2018). Recent findings also attested to the convergent validity of the P Scale with implicit measures of positivity (using the implicit association test), self-perceived intelligence (Costantini et al, 2019), and dispositional flow (Riva et al, 2017).…”
