Grounded in the positive psychology paradigm the recently recognised core construct of psychological capital was focussed in a South African study. A non-experimental, correlational study (n=204) examined the relationship between authentic leadership, psychological capital, psychological climate, team commitment and intention to quit. The present study was exploratory in nature and the pattern of relationships being investigated had not been previously tested in a South African context. A self-administered composite questionnaire consisting of five psychological scales were distributed to employees in the junior to senior management level at a global tyre manufacturing organisation based in Port Elizabeth, South Africa. The five scales were the Authentic Leadership Questionnaire by Walumbwa, Psychological Capital Questionnaire by Luthans, Psychological Climate by Koys and DeCotiis, Team Commitment by Bennett and the Intention to Quit Scale by Cohen. All the measures applied on the South African sample were developed outside South Africa and model equivalence had to be established. The content and structure of the measures were investigated through confirmatory factor analysis and exploratory factor analysis. With the exception of the Cohen scale of intention to quit, all other measures changed their factorial structures to suit the present data. The propositions in the study were tested through descriptive statistics, t-tests, ANOVA, post hoc tests, Cohen’s d, Pearson product-moment correlation and multiple regressions. Structural equation models were built to test the relationships between the scales and sub scales of authentic leadership, psychological capital, psychological climate, team commitment and intention to quit. Results of the analyses carried out, show significantly strong relationships between the variables. Of note is the marked relationship between authentic leadership and psychological climate. Most of the propositions were accepted in light of the relationships that emerged. The proposition indicating structural equation models was rejected because none of the models built in the study successfully produced an adequate fit on the data. Contributions of the study were in terms of the portability of the measurement instruments applied in the study as well as the relationships that emerged. Re-validation of the measures is required to enable clarity on how the variables in the study are interpreted across cultural contexts. Directions for future research include extending the study to other samples and other cultures. Measuring social desirability of the instruments could possibly provide clarity on how the different samples respond to the measures. Studies that compare the reading ability as well as the ability to comprehend the items in the measures would provide valuable information.
