- Validity and reliability evidence of the psychological capital questionnaire-12 in a sample of Mexican workersPublication . Santana-Cardenas, Soraya; Viseu, João; Lopez Nunez, Maria Inmaculada; Neves de Jesus, SaulPsychological capital is a construct that is included in the positive organizational behavior framework, which is based on positive psychology principles. This concept is composed by four dimensions, self-efficacy, hope, resilience, and optimism, which have a synergistic action. The aim of this study was to report the psychometric properties of one of the measures of psychological capital, the Psychological Capital Questionnaire-12 (PCQ-12), in a sample of 396 Mexican workers. This instruments' factor structure was analyzed through a confirmatory factor analysis. Reliability was assessed with the Cronbach's Alpha and Composite Reliability coefficients. Furthermore, convergent and discriminant validity were also evaluated. Based on three concurrent models, it was observed that the model which possessed a better fit was composed by four-correlated factors. The implications of these results are discussed, and recommendations are provided for future researches. This paper, which presents a different factor structure than the usual of psychological capital, suggests that cultural differences may play a crucial role on the way the assessed construct behaves.
- Psychological Capital of Spanish Workers: Confirmatory Factor Analysis of PCQ-12Publication . Inmaculada Lopez-Nunez, Ma; Neves de Jesus, Saul; Viseu, João; Santana-Cardenas, SorayaBackground: The concept of positive psychological capital draws from the study of positive organizational behavior and refers to a psychological state characterized by self-efficacy, hope, resilience, and optimism that can be developed and related to job performance. Methods: This paper analyzed the reliability and factorial structure of the Psychological Capital Questionnaire-12 (PCQ-12) in a sample composed by Spanish workers (N = 339), from different professional sectors, through a confirmatory factor analysis (CFA). Results: The analysis assessed a model with four-correlated factors competing with a second-order model proposed by the authors of this instrument. The results of the adjustment and reliability values of the dimensions are discussed in light of various studies which differ from our model or support it along with its limitations and contributes. Conclusion: Our results indicate the need to contemplate this instrument's sensitivity towards cultural differences, both geographical and organizational.
