Article Synopsis
- This study analyzed the internal structure and psychometric properties of the PHQ-9 depression questionnaire among Puerto Rican workers, revealing mixed evidence about its unidimensionality.
- A sample of 955 participants was used, with analyses including confirmatory factor analysis and bifactor testing, leading to a bifactor model as the best fit for the data.
- The findings indicate the PHQ-9 is a reliable measure for depression, supporting its use in occupational health psychology and demonstrating measurement invariance across sexes.
The aim of the current study was to examine the internal structure and assess the psychometric properties of the Work-Related Rumination Scale (WRRS) - Spanish version in a Puerto Rican sample of workers. This instrument is a 15-item questionnaire, which has three factors, affective rumination, problem-solving pondering, and detachment. This measure is used in the occupational health psychology context; however, there is little evidence of its psychometric properties.
