ORIENTATION: Researchers need to assess the psychometric rigour of resilience measuring scales. RESEARCH PURPOSE: The purpose of the study was to assess the psychometric properties of the South African Adult Resilience Indicator (ARI). MOTIVATION FOR THE STUDY: Researchers have not previously published the psychometric properties of the South African Adult Resilience Indicator. RESEARCH DESIGN, APPROACH AND METHOD: The authors used a cross-sectional quantitative research design. A sample of 789 young adults participated in the study. Cross-validation allowed the authors to confirm (using the validation sample) the validity of the ARI structure they obtained during initial testing (using the calibration sample). They investigated two measurement models (the original factor structure and a one-dimensional factor structure). MAIN FINDINGS: The original factor structure presented the data and the proposed theory better than did the one-dimensional factor structure. The authors found acceptable goodness of fit for the ARI. More specifically, they found invariance (in terms of equal factor loadings, covariances and error variances) in the calibration and validation samples. They also found acceptable reliability estimates for each of the eight sub-scales. PRACTICAL/MANAGERIAL IMPLICATIONS: The results can help researchers and practitioners interested in measuring resilience in adults to choose a resilience measure and to select an appropriate measure for their populations and contexts. CONTRIBUTION/VALUE-ADD: Previous research has clearly shown that reliable and valid resilience measures are necessary. It is also necessary to assess the psychometric properties of the currently available instruments and to publish the findings. This study has helped by examining the psychometric properties of the South African Adult Resilience Indicator.
