BackgroundThe Dispositional Flow Scale-2 (DFS-2) is an instrument for measuring the flow experiences of the general population while participating in daily activities. This study aimed to examine the equivalence in the measurement structure of Traditional Chinese DFS-2 (TCDFS-2) between the schizophrenic patients and healthy subjects.MethodsWe recruited 100 adults with schizophrenia or schizoaffective disorder from the psychiatric clinics or the centers for daycare or rehabilitation and 104 healthy adults. Each participant finished the TCDFS-2 by recalling the most important and meaningful daily activity.ResultsWe conducted two two-group confirmatory factor analyses (CFA) with the healthy subjects and schizophrenic patients as the reference group respectively in LISREL. When the healthy subjects as the reference standard, 43 items of the TCDFS-2 were added to this constrained two-group CFA model for the schizophrenic patients, but the cross-group equivalence was still unsatisfactory. By contrast, when the schizophrenic patients as the reference standard, only 6 items were added for the healthy subjects, and the cross-group equivalence was barely acceptable.ConclusionThus, the measurement structures of the TCDFS-2 were quite different between the schizophrenic patients and healthy subjects. The flow states experienced by the schizophrenic patients might not entirely be the same as those of the healthy subjects.Copyright © 2022. Published by Elsevier B.V.
