“…For example, personality traits emerged as use-ful predictors of treatment outcome in patients with gastrointestinal disorders [5] , obesity [6] , hyperopia [7] and even individual responses to certain surgical treatments seem to be associated with personality [8,9] . In psychiatry, personality traits have been successfully linked to treatment outcome in depression [10] , anorexia nervosa [11,12] , schizophrenia [13] and withdrawal severity in benzodiazepine dependence [14] .…”

Personality Traits Predict Treatment Outcome in Alcohol-Dependent Patients

Personality traits are important individual characteristics modifying responses to therapy in various diseases. The aim of this study was to identify personality traits that may predict treatment outcome in alcohol-dependent patients. The present analysis was based on a total of 146 alcohol-dependent patients (109 male, 37 female) after detoxification. The variable of interest was treatment outcome (abstinence/relapse) after a 1-year follow-up. To identify personality traits as predictors of treatment outcome, 5 personality questionnaires (NEO 5-Factor Inventory, Temperament and Character Inventory, Eysenck Personality Questionnaire, Eysenck Impulsiveness-Venturesomeness-Empathy Scale and Sensation-Seeking Scale) were applied. Data analysis was performed by using a classification and regression tree analysis (CART; a nonparametric technique for data with a complex structure) in order to find a decision rule to predict treatment outcome from personality traits. The CART model identified psychoticism and persistence as the 2 most relevant discriminatory parameters, of which psychoticism was used as the first node in the model, classifying 64% of the patients correctly as relapsed and 12% correctly as abstinent. In addition, the risk of relapse was even higher in patients with a substantial score in psychoticism and a low score in persistence. When comparing relapsed and abstinent patients, further variables, such as scores for novelty seeking (20.9 ± 5.5 vs. 18.5 ± 5.9) and impulsiveness (8.4 ± 3 vs. 7.2 ± 3.5), showed significance. In addition, relapsed patients lived alone more often than abstinent patients (52 vs. 25%, p = 0.004). In conclusion, this analysis demonstrated that specific personality characteristics, namely psychoticism and persistence, are usable predictors for the risk of relapse in alcohol-dependent patients.

“…[10][11][12][13] However, some authors have investigated the effect of obesity surgery on personality. In two different studies, using the Minnesota Multiphasic Personality Inventory (MMPI) and Eysenck Personality Inventory, Bull et al 14,15 note that although the operated patients were less depressed, surgery was not accompanied with any significant changes in personality. However, since comparisons were made between different groups of people preoperatively and at different follow-up intervals, the lack of changes might simply be an artefact of possible initial differences.…”

“…He described the mental processes in terms of psychosomatic personality characteristics along with the concepts of pensée opératoire described by Marty and De M 'Uzan [3] and of alexithymia introduced by Sifncos [4], In some studies a direct connection between obesity and alexithymie traits was found in adult subjects [5][6][7], Two recent studies [8,9] supported this point of view on the basis of Rorschach test protocols and facial emo tion decoding ability tests carried out in obese children.…”

Background: The relationship between developmental obesity and emotional problems has been particularly studied by Bruch. According to this author, the main reason for early-onset obesity has to be found in the difficulty of some mothers to adequately distinguish between emotional manifestations and the child’s real need for food. In this paper an experiment was carried out in order to test the relationship between developmental obesity and poor ability to recognize facial expressions of some basic emotions. Methods: A group of 20 mothers whose children suffered from serious early-onset obesity (experimental group) and another group of 20 mothers, whose children had slight overweight problems arising long after the first year of life (control group), were tested. Both mothers and their children were asked to recognize a set of facial expressions of emotions. 42 slides of facial expressions of emotions (anger, sadness, disgust, surprise, fear, happiness and neutral faces) were presented to subjects who were asked to mark on an answer sheet the name of the emotion expressed by the actor’s face. Results: A significant difference between the groups was found: a larger number of errors in the recognition of facial expression of emotions was made by mothers and their children in the experimental group. Furthermore a positive linear correlation between the number of errors made by the mothers and that made by their children was present. Conclusions: The findings do support Bruch’s clinical observations. Further studies concerning other emotional signs (either nonverbal or verbal) are needed in order to assess the importance of emotional decoding difficulties in developmental obesity.
