Following its development, the instrument underwent expert validation and a pilot test, including exploratory and confirmatory factor analyses. Content and construct validity, as well as internal consistency, were analyzed.Results: the SATUS-APS scale showed high item-level content validity (.85–.94) and internal consistency (α=.83). Exploratory factor analysis identified six factors explaining 58.4% of the variance, with appropriate statistical fit (RMSEA=.045, CFI=.976), requiring modifications. The final model included 18 items, showing acceptable fit (CMIN/DF= 2.87, CFI=.976, TLI=.940, SRMR=.0471, RMSEA=.0404, p<.001) and excellent overall reliability (α=.968).Conclusions: the questionnaire demonstrated validity and reliability for measuring user satisfaction. Its structure was confirmed through factor analysis, and reliability coefficients were high across all dimensions. It is a useful tool for research and quality improvement in health services.
