Psychometric properties of the Psychological Capital Questionnaire (KKaPsy)

BACKGROUND: The aim of the study was to prepare and design a Polish version of the Psychological Capital Questionnaire. The psychometric tool allows synthetic assessment of four personal resources known to play a significant role in effective functioning, viz. self-efficacy, hope, optimism and resilience. PARTICIPANTS AND PROCEDURE: The psychometric properties of the questionnaire were developed in two studies, the first one involving 308 people (166 women and 142 men) and the second involving 206 people (111 women and 95 men). RESULTS: Confirmatory factor analysis confirmed that the tool has a four-component structure with an overall score. It is characterized by satisfactory internal consistency (α = .73-.86), stability (rtt = .85-.92) and construct validity. CONCLUSIONS: The Psychological Capital Questionnaire is a reliable and valid tool that can be used in research and in practice.
