The objective of this study was to analyze the psychometric properties of the Spanish version of the Eysenck Personality Questionnaire Revised-Abbreviated (EPQR-A) in informal caregivers. Trained, independent evaluators administered the EPQR-A and evaluated informal caregivers' depressive symptoms, automatic negative thoughts, self-efficacy, and pleasant social contacts, and clinical experts assessed major depressive episode in 592 caregivers (87.2% women, mean age 55.4 years). Women scored significantly higher on Neuroticism than men (p < .001).
