| Abstract: | Procrastination has been defined in different ways. Two instruments—the Irrational Procrastination Scale (IPS) and the Pure Procrastination Scale (PPS)—focus on a core problem in procrastination—the irrational delay of intended behavior. The present paper examined the psychometric properties of the Norwegian translations of these scales. In five samples with students as well as non-students (aggregated n?=?1045), standard psychometric properties of the instruments were assessed and their factor structures were compared in replication analyses. In addition, correlations between the instruments as well as other instruments (i.e., the Susceptibility to Temptation Scale and the Satisfaction with Life Scale) were examined to determine convergent and divergent validity. Overall, the results indicated that both IPS and PPS are suitable for use as measures of procrastination. |
