摘要	This study investigated the effect of dual task performance of hand dexterity tasks and the relationship to daily functioning in 40 people with chronic schizophrenia and 35 healthy participants. Participants performed the Purdue Pegboard Test, O’Connor Finger Dexterity Test, and the Serial Subtracting Seven Task as the secondary task under single- and dual-task conditions and completed the Activities of Daily Living Rating Scale–III (ADLRS-III). The hand dexterity of all participants declined from the single to the dual tasks, and the discrepancy between single- and dual-task performance was significantly greater in the schizophrenia group than in the control group. Significant condition and group effects were found for both hand dexterity tests. People with schizophrenia who took longer time in performing hand dexterity tasks had significantly worse daily life function. Negative correlations were noted between discrepancy of dual tasking and the ADLRS–III score in the schizophrenic group. Deficits in dual-task performance of hand dexterity is significant in people with schizophrenia and is related to daily life performance. Occupational therapy practitioners can consider using dual tasks as a therapeutic activity for people with schizophrenia to promote functional abilities in real-world environments.
