Validation of Psychological Capital Questionnaire in Thai employees

Abstract

Although the construct psychological capital was first introduced by Luthan, the concept has been developed in attaining competitive advantage and supporting unity between employee and organization within a western context. There is much less attention in Asia, especially in Thailand. This current study therefore aimed to develop and initially validate a Psychological Capital Questionnaire (PCQ) in Thai employees. The original PCQ consisted of 4 subscales (i.e., self-efficacy, hope, resilience, and optimism) with 24 items in total. The new instrument developed in this study has 60 items. Participants were 120 Thai employees from various private organizations in Bangkok Metropolis. They were recruited by convenience sampling method. Corrected item-total correlation, internal consistency reliability (cronbach’s alpha test), and confirmatory factor analysis were used to analyze the data. After a first principle component analysis on the items of the newly developed, the 60 items were reduced to 24 items measuring four dimensions of the new PCQ. Confirmatory factor analysis confirmed that the four factors of the PCQ significantly fitt the data (c2 = 2.46, df = 2, p = .292, GFI = .990, AGFI = .949, RMSEA = .044). Internal consistency for the four subscales and the new PCQ was good, considering that cronbach’s alpha coefficients ranged from 0.80 to 0.95. This study demonstrated that the 24-item PCQ in Thai version has good psychometric properties and thus is an useful instrument for measure employee’s psychological capital which is beneficial for improving job performance and promoting good work conditions in Thai organizations.
