Abstract
Background: One of the most traditional approaches to the positive study of personality has been the research on Hardiness or Hardy Personality. However, studies about this construct have systematically suffered from a lack of sufficient psychometric guarantees of the measures. Method: This paper presents the Occupational Hardiness Questionnaire (OHQ), the result of a research line on the subject and its measurement with a total sample of 1,647 participants. Results: Four studies show the results of exploratory factor analysis (EFA), confirmatory factor analysis (CFA), consistency, temporal reliability and construct validity. Conclusions: Results indicate that the OHQ has satisfactory psychometric characteristics and can be used in the study of Occupational Health and in the area of Positive Personality.
