Background: Cancer is a public health problem, and stress is one of the psychosocial variables associated to this disease, which calls for the need to have a reliable scale to measures stress in the Hispanic population with cancer. Objective: To determine the psychometric properties of the Measurement of Current Status (MOCS) Scale in Mexican cancer patients. Method: Study design: Cross-sectional, non-experimental instrumental. A total of 197 patients aged 18-81 years, at any clinical stage, receiving cancer treatment or follow-up were included. Instruments: MOCS and emotional distress thermometer. Statistical analysis: Confirmatory factor analysis was performed to evaluate the fit of the model to the data using the maximum likelihood estimation and cut-off points. Results: Two models were obtained. The first, self-perceived current state, had an alpha of .90 with an explained variance of 74.2 %; the second, non-specific effect, with an alpha of .61 and an explained variance of 74.3 %. The confirmatory factor analysis showed that both models had indexes suggesting stability and acceptable adjustment. Scores are shown by interquartile ranges for each model. Conclusions: The Mexican version of the MOCS is reliable and valid; with a confirmatory factor structure similar to the original version. Therefore, we support its use in the clinical and research setting with cancer patients.
