Résumé : | Importance: Patients with schizophrenia tend to have severe deficits in theory of mind, which may limit their interpretation of others' behaviors and thereby hamper social participation. Commonly used measures of theory of mind assess the ability to understand various social situations (e.g., implied meaning or hinting, faux pas), but these measures do not yield valid, reliable, and gender unbiased results to inform interventions for managing theory-of-mind deficits. We used understanding of implied meaning, which appears to be a unidimensional construct highly correlated with social competence, as a promising starting point to develop a theory-of-mind assessment. Objective: To develop a Rasch-calibrated computerized test of implied meaning. Design: Cross-sectional design. Setting: Psychiatric hospitals and community. Participants: 344 participants (240 patients with schizophrenia and 104 healthy adults). Results: We initially developed 27 items for the Computerized Implied Meaning Test. After inappropriate items (12 misfit items and 1 gender-biased item) were removed, the remaining 14 items showed acceptable model fit to the Rasch model (infit = 0.841.16; outfit = 0.651.34) and the one-factor model (comparative fit index =.91, standardized root mean square residual =.05, root-mean-square error of approximation =.08). Most patients (81.7%) achieved individual Rasch reliability of ≥.90. Healthy participants performed significantly better on the test than patients with schizophrenia (Cohen's d = 2.5, p <.001 conclusions and relevance: our preliminary findings suggest that the computerized implied meaning test may provide reliable valid gender-unbiased results for patients with schizophrenia. what this article adds: we developed a new measure assessing theory-of-mind ability in schizophrenia consists of items targeting understanding meaning. is gender unbiased be used evaluating deficits relevant factors. study to inform interventions manage> |
