Psychometric Properties of the Persian Version of the Pure Procrastination Scale in College Students

Abstract

Objectives: This study aims to investigate the psychometric properties of the Persian version of the Pure Procrastination Scale (PPS) including reliability, validity, measurement invariance, and factor analysis. Methods: In this cross-sectional study, 390 college students from the three universities in Tehran participated. They completed a battery of four self-report tools including the PPS, Difficulties in Emotion Regulation Scale (DERS), Depression, Anxiety and Stress Scale-21 (DASS-21), and Satisfaction with Life Scale (SWLS). Results: The Exploratory Factor Analysis (EFA) results confirmed the three-factor solution of the Persian PPS which were decisional procrastination, implemental delay, and timeliness. The results of multi-group confirmatory factor analysis showed the between-group invariance of the factor structure, measurement weights, structural covariances and measurement residuals of PPS for demographic variables. The results revealed high internal consistency and high test-retest reliability. There Persian PPS and its subscales had statistically significant correlations with DASS-21, DERS, and SWLS. Conclusion: The Persian PPS has good reliability and validity for assessing procrastination in Iranian population.
