Abstract

Given the prevalence of mental disorders and elevated psychological symptoms, there has been a call for action to scale up health services. To provide optimal care, detecting symptoms early and evaluating the psychological state is essential. Self-report measures are useful to evaluate specific diagnoses and explore psychological symptoms. The present study aimed to provide new psychometric evidence of the Argentine version of the Brief Symptoms Checklist. Through non-probabilistic and intentional sampling, 760 individuals aged 18 to 63 (M = 28.1; SD = 8.61) were selected. Confirmatory factor analysis showed that the nine correlated factors model exhibited the best-fit indices and yielded full configural, metric and scalar invariance across gender and region. The factors mainly showed adequate reliability values similar to previous research. T values are provided as population-based norms. The results showed that the instrument is valid and reliable, and could be a valuable tool in various contexts, particularly in primary care, where the evaluation requires a very short time and useful information.
