Reiability, validity and factor analysis of Pure Procrastination Scale

Procrastination as a self-regulatory deficiency is considered as one of the main factors in several personal and interpersonal problems.

The main purpose of the present study was to examine psychometric properties of the Pure Procrastination Scale (PPS) including internal consistency, test-retest reliability, convergent/discriminant validity, and construct validity. Mehtod: Four hundred and eighty seven students (263 girls, 224 bpys) were included in this study. All participants were asked to complete the PPS, Tehran Multidimensional Perfectionism Scale (TMPS), Ego-Strength Scale (ESS), and Mental Health Inventory (MHI-28).

Test-retest reliability and internal consistency of the PPS were examined at satisfactory levels. The PPS revealed negative associations with self-oriented perfectionism (p>0/001), ego- strenght (p<0/001), and psychological well-being (p<0/001), as well as significant positive associations with other-oriented perfectionism (p<0/001), socially prescribed perfectionism (p<0/001), and psychological distress(p<0/001). These results confirmed the convergent and discriminant validity of the PPS.

Preliminary results of exploratory factor analysis confirmed a general factor for the PPS. Based on the results of the present study, it was concluded that the PPS can be considered as a reliable and valid scale to measure procrastination in Iranian samples.
