Аннотация
OBJECTIVES: "Schizotypy" is a term describing personality traits reflected in emotional, perceptual and cognitive styles. Affective temperaments are trait-like features which were observed to be stable in time and predispose to mood disorders. The purpose of this study was to examine relationship between schizotypal features, affective temperaments and anhedonia in patients with bipolar depression.
METHODS: 54 patients with bipolar depression were included in the study. Participant were administered the following psychometric tools: Dimensional Anhedonia Rating Scale (DARS), Snaith-Hamilton Pleasure Scale (SHAPS), Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A), and Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR). Correlations between the variables were calculated and linear regression models were built.
RESULTS: Only hyperthymia (affective temperament) and introvertive anhedonia (schizotypal domain) were statistically significantly correlated with anhedonia. In regression models, introvertive anhedonia predicted higher whereas hyperthymic features lower severity of anhedonia (measured by the SHAPS scale).
CONCLUSIONS: Hyperthymic features are protective and introvertive anhedonia is a risk factor for consummatory anhedonia.
