This study investigated the relation of hemispatial inattention to the performance of daily functions in 32 patients with schizophrenia or schizoaffective disorder and in 31 healthy controls. They were tested on the relationship between a target cancellation task and the Activities of Daily Living Rating Scale-II (ADLRS-II). According to the results of the hemispatial inattention test, the patients with schizophrenia made more omissions in the cancellation test than the controls. In addition, the results showed a significant correlation between number of omissions on the cancellation test and the ADLRS II score in the study participants. A statistically significant relationship was observed between hemispatial inattention and the functional status of patients with schizophrenia, and suggests the need to incorporate measures of visual attention into psychiatric rehabilitation assessments. ; 職能治療學系暨研究所 ; 醫學院 ; 期刊論文
