Previous issue date: 2016-11-29 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Over the past 30 years, the prevalence of obesity in the world has doubled, and according to national surveys, about 18% of Brazilians are obese. Obesity is associated with risks to physical and psychological health and a great share of prevention and modification of this multifactorial condition relies on behavior changes. However, some psychological aspects may be barriers to successful treatments, especially when eating is associated with regulation of aversive emotional states. The Dialectical Behavior Therapy (DBT) is an approach that conceptualize problem behaviors as effective attempts to regulate emotions in the short term, but not effective in the long-term. Therefore, it is a central goal in DBT that individuals learn a new repertoire of skills that help to deal with emotions. Section 1 of this study analyzes the effects of a 10 session intervention based on DBT Skills Training on emotion regulation, psychiatric symptoms and dysfunctional and adaptive eating behaviors in obese adults who were randomly assigned to intervention group or to a waiting list comparison condition. This study had measures at pre and posttest, and was quasi experimental. Inclusion criteria were (a) BMI equal to or over 30, (b) adults aged 18 to 59 and (c) at least 8 years of formal study. Participants were excluded if they presented (a) psychotic symptoms, (b) active suicidal ideation or attempted suicide over the last year, (c) the use disorders substances and (d) that had already received any treatment with DBT components. The scales used in the pretest and posttest were Difficulties in Emotion Regulation Scale (DERS), Binge Eating Scale (BES), Emotional Eating Scale (EES), Intuitive Eating Scale (IES-2), Mindful Eating Questionnaire (MEQ) and Depression, Anxiety and Stress Scale (DASS-21). The sample consisted of 31 obese subjects divided into intervention group (n = 14) and waiting list (n = 17). Based on the large effects sizes, the results show that the intervention based on DBT skills training might be effective in reducing the severity of binge eating, improving depressive symptoms and increasing adaptive eating behaviors such as intuitive eating, that is, eating more connected with physiological signals of hunger and satiety. However, the study lacks statistical power to support strong conclusions. These results are therefore preliminary and require replications with larger samples. Section 2 aimed to analyze the semantic equivalence of the DERS for Brazilian Portuguese. For that, it was utilized a five-step adaptation process: (1) translation; (2) back translation; (3) correction and semantic adaptation with the author of the original instrument; (4) content validation by expert judges (n = 10) and; (5) assessment by the general population through a numeric verbal scale (n = 28). The results show that the final version had satisfactory semantic equivalence, with good comprehensibility by expert judges and general population and final approval of the author of the original instrument. / Nos ?ltimos 30 anos, a preval?ncia da obesidade no mundo dobrou e de acordo com levantamentos nacionais, cerca de 18% dos brasileiros est?o obesos. A obesidade traz riscos ? sa?de f?sica e psicol?gica e grande parte da preven??o e modifica??o desta condi??o multicausal depende de modifica??es no comportamento. Entretanto, alguns aspectos psicol?gicos podem ser entraves para tratamentos bem-sucedidos, j? que o comer as vezes pode estar associado a fun??o de regular estados emocionais aversivos. A Terapia Comportamental Dial?tica (TCD) ? uma abordagem que sugere que comportamentos problema podem ser tentativas efetivas a curto prazo para regular emo??es, por?m trazendo preju?zos a longo prazo. Por isto, ? central na TCD que os indiv?duos aprendam um novo repert?rio de habilidades que auxiliem a lidar com as emo??es. Na Se??o 1 deste estudo foi avaliado o efeito de uma interven??o de 10 sess?es baseada no Treinamento de Habilidades da TCD sobre a regula??o emocional, sintomas psiqui?tricos e comportamentos disfuncionais e adaptativos em obesos adultos que foram randomizados para a condi??o interven??o ou para uma lista de espera. Foi utilizado um delineamento quase experimental longitudinal, com medidas no pr?-teste e p?s-teste. Os crit?rios de inclus?o foram (a) IMC igual ou acima de 30, (b) adultos com idade entre 18 e 59 anos e (c) pelo menos 8 anos de estudo formal. Foram exclu?dos participantes que possu?ssem (a) sintomas psic?ticos, (b) idea??o suicida ativa ou tentativa de suic?dio ao longo do ?ltimo ano, (c) os transtornos por uso de subst?ncias e (d) que j? haviam recebido qualquer tratamento com componentes da TCD. Os instrumentos utilizados no pr?-teste e p?s-teste foram a Difficulties in Emotion Regulation Scale (DERS), Escala de Compuls?o Alimentar Peri?dica (ECAP), Emotional Eating Scale (EES), Intuitive Eating Scale (IES-2), Mindful Eating Questionnaire (MEQ) e Depression, Anxiety and Stress Scale (DASS-21). A amostra foi composta por 31 indiv?duos obesos divididos em Grupo Interven??o (n = 14) e lista de espera (n = 17). Com base nos grandes tamanhos de efeito, os resultados mostraram que uma interven??o baseada no treinamento de habilidades da TCD pode ser eficaz na redu??o da gravidade da compuls?o alimentar, na melhora de sintomas depressivos e no aumento de comportamentos alimentares adaptativos, como o comer intuitivo, mais conectado com sinais fisiol?gicos de fome e saciedade. No entanto, o estudo n?o possui poder estat?stico para conclus?es fortes. Estes resultados s?o, portanto, preliminares e exigem repeti??es com amostras maiores. A Se??o 2 teve objetivo analisar a equival?ncia sem?ntica da DERS para o portugu?s brasileiro. Para isto um processo de adapta??o foi realizado em cinco etapas: (1) tradu??o; (2) tradu??o reversa; (3) corre??o e adapta??o sem?ntica com a autora do instrumento original; (4) valida??o de conte?do por ju?zes especialistas (n = 10) e; (5) avalia??o pela popula??o geral atrav?s de uma escala verbal num?rica (n = 28). Os resultados apontam que a vers?o final manteve equival?ncia sem?ntica satisfat?ria, com bons n?veis de compreensibilidade pelos ju?zes especialistas e popula??o geral e aprova??o final da autora do instrumento original.
