Contribution to the italian adaptation of the general procrastination scale

Background: Although procrastination is an important and widespread phenomenon (Ferrari et al., 1995), there are few scales which measure the construct. This study describes a psychometric assessment of the Italian version General Procrastination Scale (GPS) developed by Lay (1986). Methods: The Italian version of the GPS was administered to 454 adult individuals. Results: The exploratory and confirmatory factor analyses provide evidence that the Italian version of the GPS is not unidimensional scales. More models were tested; the best model had two factors (Tendency to postpone tasks and Getting tasks done on time) and used 13 item. The mean composite scores for two factors did not differ by gender. Conclusions: The results show that a model with two factor had good psychometric proprieties. However further research is necessary for the GPS Italian validation.
