Objective: To test the reliability and one-factor structure of the PDS among university students from Arequipa in Peru. Materials and methods: This is an instrumental study. A non-probability sample of 165 university students from a private university at Arequipa was collected. The PDS was applied. This scale is composed of 10 items and counts with adequate values of validity and reliability. Results: We found that the scale have a one-factor structure and adequate levels of reliability computed through α and ω coefficients. Conclusions: The PDS is reliable and the one-factor structure is valid, but it is necessary to provide more evidences of validity, such as testing its relationship with family and academic achievement variables.
