GROBLER, Anton  e  JOUBERT, Yvonne T.. Psychological Capital: Convergent and discriminant validity of a reconfigured measure. S. Afr. j. econ. manag. sci. [online]. 2018, vol.21, n.1, pp.1-14. ISSN 2222-3436.

BACKGROUND: Although attention has been given to the importance of positivity in the workplace, it has only recently been proposed as a new way in which to focus on organisational behaviour. The psychological resources which meet the criteria for positive organisational behaviour best are hope, self-efficacy, optimism and resilience AIM: The purpose of this study was to investigate the construct validity of the Psychological Capital Questionnaire (PCQ), with specific reference to its psychometric properties SETTING: The sample included a total of 1749 respondents, 60 each from 30 organisations in South Africa METHODS: A multi-factorial model was statistically explored and confirmed (with exploratory factor analysis and confirmatory factor analysis, respectively RESULTS: The results support the original conceptualisation and empirically-confirmed factorial composition of Psychological Capital (PsyCap) by four elements, namely Hope, Optimism, Resilience and Self-efficacy. However, the study yielded a three-factor solution, with Hope and Optimism as a combined factor and Resilience and Self-efficacy made up of a reconfigured set of substantively justifiable items (three of the original 24 items were found not to be suitable). The three reconfigured factors showed good psychometric properties, good fit (in support of construct validity) and acceptable levels of convergent and discriminant validity. Recommendations were made for further studies CONCLUSION: Based on the results obtained, it seems that the PCQ is a suitable (valid and reliable) instrument for measuring PsyCap. This study could thus serve as a reference for the accurate measurement of PsyCap
