The Psychometric Properties of the Prioritizing Positivity Scale

The tendency to use pleasant states as a key criterion for how to structure daily life is called prioritizing positivity and has been measured with a 6-item scale. The Prioritizing Positivity Scale (PPS) is increasingly being used by researchers, but a comprehensive examination of its psychometric quality remains absent from the literature. Using three independent samples of adults (study 1: n = 176, study 2: n = 240, study 3: n = 226), we tested the scale's (1) factor structure, (2) reliability, (3) convergent and discriminant validity, and (4) measurement invariance. Results suggested that the 6th item was problematic (low factor loading, conceptually distinct from other items) and when removed, a single-factor structure was appropriate. The revised 5-item PPS demonstrated satisfactory reliability, construct validity and measurement invariance. The revised 5-item PPS offers a brief and valid way to measure a personality difference shown to predict well-being.
