PURPOSE Intensive care unit survivors experience new and ongoing physical, psychological, and cognitive complications known as postintensive care syndrome. The study aimed to investigate the psychometric properties of the healthy aging brain care monitor self-report tool for assessing postintensive care syndrome in Iranian patients. METHODS The study is a methodological study investigating the psychometric properties of the healthy aging brain care monitor self-report tool in 153 patients discharged from the intensive care unit. The instrument's psychometric properties were examined to determine content validity, construct validity (factor analysis, convergent validity, and discriminant validity), concurrent validity, and internal consistency. FINDINGS The factor structure of the healthy aging brain care monitor self-report tool was examined in the form of two models: the three-factor model with 27 items and the three-factor model with 19 items. Regarding fit indices and results of the convergent, discriminant validities and the internal consistency the 19-item model is better than the original 27-item model. CONCLUSIONS The study showed that the appropriate model for the healthy aging brain care monitor self-report tool in Iranian society is a tool with 19 items with the best conditions in terms of factor structure, internal consistency, and overall psychometric characteristics. IMPLICATIONS FOR NURSING PRACTICE The present study led to the introduction of a valid instrument with a 19-item factor structure to assess the postintensive care syndrome by nurses and other healthcare providers in hospitals, clinics, palliative care centers, and home care centers.
