Abstract

Introduction: Anhedonia nowadays consists of one of the main symptoms when talking about Mood disorders and some cases of Schizophrenia. Anhedonia was first documented by Ribot (1896) as the loss of ability to experience pleasure and has been recognized as a central feature of depression. The diagnosis of major depressive disorder by DSM-IV requires that depressed mood or anecdotal be present for a correct diagnosis. Despite the importance of anhedonia in depression, little is known about the evaluation of this symptom in the context of depressive psychopathology Objective: The present study aims to determine the psychometric properties of the Snaith-Hamilton Pleasure Scale (SHAPS) in Portuguese. Methodology: A cross-sectional study of the type validation, using a convenience sample of 252 from the service of parenchymal diseases of the liver of Professor Edgard Santos University Complex. The snaith-Hamilton scale was translated based on the American research group. Data were collected from the Snaith-Hamilton and HAD scales. Results: After the Kolmogórov-Smirnov and Shapiro-Wilk tests, a P less than 0.001 was obtained. The Spearman test was then applied for correlation, obtaining a ρ = 0.249. Conclusions: The SHAPS version in Brazilian Portuguese shows that this instrument has good validation and application to measure pleasure and its current and anticipated experimentation, when translated into Brazilian Portuguese and applied in the local culture of Brazil.
