Factorial Structure of Three Procrastination Scales with a Spanish Adult Population
Abstract
The present study explored the factorial structure of three well-known procrastination measures: the General Procrastination Scale (GP; Lay, 1986), the Adult Inventory of Procrastination (AIP; McCown & Johnson, 1989), and the Decisional Procrastination Scale (DP; Mann, 1982) with 502 Spanish adults between 25 and 67 years old. The principal component analysis indicated a one-factor structure for GP and DP, and two factor components for AIP. The internal consistency of the three scales was satisfactory. Results suggested that the Spanish versions of the three procrastination scales were effective and reliable. Finally, a principal component analysis with the three scales indicated a four-factor model of procrastination, namely: dilatory behaviors, indecision, lack of punctuality, and lack of planning.
