ABSTRACT
INTRODUCTION: Anhedonia is a critical symptom of major depressive disorder and is defined as the reduced ability to experience pleasure. The Temporal Experience of Pleasure Scale (TEPS) is commonly used to measure anhedonia and presents satisfactory reliability.
OBJECTIVES: We aim to perform the transcultural adaptation of the Brazilian version of the TEPS and evaluate its psychometric properties.
METHOD: The cross-cultural adaptation was performed according to previously established protocols. Cronbach’s alpha internal consistency coefficient was used to establish the item’s degree of interrelation and coherence. Also, we used the intraclass correlation coefficient calculation to determine the stability of the scale after the proposed period and exploratory factor analysis to evaluate the structural factor and scale content. The principal component analysis estimation method determined the factors to be retained in the factorial model.
RESULTS: The participants have reported a good understanding and applicability of the Brazilian version of the TEPS. The results have shown a statistically significant correlation between the measures. The calculation of the intraclass correlation coefficient presented a significant value. The examination of the overall internal consistency of the scale showed a suitable Cronbach’s alpha value.
CONCLUSION: The proposed version of the TEPS scale in Portuguese presented a good understanding for the Brazilian population and reliability and validity regarding its psychometric characteristics.
