Psychometric Properties of the Persian Version of the Pure Procrastination Scale in College Students
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.
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).
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.
The Persian PPS has good reliability and validity for assessing procrastination in Iranian population.
