Assessing theory of mind abilities in schizophrenia and bipolar disorder: A psychometric study of the Faux Pas Recognition test in Serbian

Abstract

Theory of Mind (ToM) is a social-cognitive ability to understand the mental states of others. ToM functions are compromised in the case of mental disorders characterized by cognitive impairments. The Faux Pas Recognition test (FPRT) is considered a good measure of verbal aspects of ToM as it measures social adaptation through the adequate interpretation of potentially sensitive and awkward social situations. However, data on FPRT psychometric properties is somewhat limited. The aim of the present study is the psychometric evaluation of the FPRT in Serbian population. The adapted version in Serbian has been administered to 268 healthy participants, 30 patients with schizophrenia and 31 with bipolar affective disorder. The results show a high internal consistencies of Faux Pas stories (α = .954), Control stories (α = .929) and overall test (α = .936). Both Horn’s parallel analysis and confirmatory factor analysis indicated that a single-factor solution is optimal, supporting the premise of a general ToM ability underlying performance across test. The Faux Pas test showed good discriminative power in differentiation between individuals from healthy and clinical populations making it a useful clinical instrument.
