To date, cognitive intervention to improve executive function for patients with schizophrenia has not been ecologically validated. Our main objective was to investigate the effectiveness of grocery shopping skill program on executive function and instrumental activities of daily living (IADL) of patients with schizophrenia. Among 20 patients with schizophrenia who received conventional rehabilitation, 10 patients were allocated to an experimental group and they additionally performed the program to improve grocery shopping skill in a real situation for eight sessions. The rest of participants were assigned to the wait-list group. To identify the effects on executive function, the Korean version of the Executive Function Performance Test (EFPT-K) was used. IADL was evaluated using the Korean Instrumental Activities of Daily Living (K-IADL). After the sessions, the EFPT-K (p < .001) and K-IADL (p < .05) were significantly improved in the experimental group. These results indicate that the program to improve grocery shopping skills might be clinically beneficial to enhance executive function and IADL of patients with schizophrenia.
