RESUMO

The study aimed at the evaluation of depression, alexithymia, quality of life and personality styles of people with idiopathic Parkinsons disease. The sample of 100 participants was integrated by 41% men and 59% women, from 38 to 90 years old, aged from 50 to 79 years old (Mo=75 and 77 years old); 72,45% are pensioners; 68% are originally from Sao Paulo State; 53% with schooling from 8 years or more. The majority of the participants (59%) had the disease for 6 years and was classified as the 2nd stage of Parkinsons disease (80% of them). Participants were evaluated according to the following instruments: Beck Depression Inventory (BDI), Toronto Alexithymia Scale (TAS), Parkinson s Disease Questionnaire (PDQ- 39) and Millon Inventory of Personality Styles (MIPS). The average score of BDI was 11,8 (SD= 7,4), summing up 47% of the people with light or moderate depression. Their common symptoms were lack of pleasure, irritation, insomnia, fatigue, lack of interest in sex, concern with health and with the impossibility of working. Most of the people were scored as alexithymic (59%). Quality of life scores had an average total of 27,34 (SD=14,29). The highest scores were physical discomfort (M=32,4, SD=23,7); activities of daily living (M=31,8, DP=20,4) and mobility (M=31,0, DP=22,5). As for personality styles, 80% and more present strong characteristics called opennesss, protection, sensation, introversion, reflection, affectivity, systematization and firmness. The structure equation modeling (SEM), analyzed through Partial Least Square (PLS), showed that depression contributes significantly to quality of life, alexithymia and the dimensions of cognitive and interpersonal behaviors (evaluated by MIPS). Results were discussed considering the multidetermination of depression in Parkinsons disease and the importance of the intervention in depression focusing the improvement of quality of life. A heuristic proposal involves the theoretical model about a multidetermination of the depression in the illness as a model obtained in this study following PLS. The limitations imposed by the homogeneity of some characteristics of the sample are discussed and new studies are suggested, including samples with different characteristics and on psychotherapy interventions that consider psychological disorders and the positive aspects (adaptive resources) identified in this research.
