O objetivo deste estudo foi elaborar e descrever as características de um protótipo brasileiro de Terapia Comportamental Dialética (DBT) para ser utilizado em investigações de processos e processos-resultados. Para tanto, 10 experts brasileiros em DBT responderam a um questionário sociodemográfico e ordenaram os 100 itens do Psychotherapy Process Q-Set (PQS) de acordo com o que avaliaram ser uma sessão ideal nessa psicoterapia. Houve alto nível de concordância entre os participantes (α= 0,94), e a análise de componentes principais do tipo Q diferenciou o protótipo de DBT dos protótipos de outras abordagens utilizadas para comparação. Foram identificadas correlações entre os distintos modelos psicoterápicos analisados, fomentando a discussão sobre os fatores comuns, e a natureza heterogênea da DBT e da amostra de experts brasileiros. Tais resultados possibilitam que o protótipo elaborado seja utilizado em investigações das múltiplas variáveis presentes no processo terapêutico deste modelo de tratamento.

The Reinforcement Sensitivity Theory (RST) is a widely studied psychobiological model of personality. RST factors seem to influence eating behavior, but how these personality traits are associated with distinct features of eating behavior is still unclear. In the present systematic review, we analyzed the relationship between RST personality factors and eating behavior using a parsing approach in which BMI-related results, self-reported results, and behavioral results were distinguished. Our analysis revealed that reward and punishment sensitivity seem to correlate and influence distinct features of eating behavior. The association between BMI and RST factors was uncertain, but nonlinear associations between reward sensitivity and weight need further testing. Reward sensitivity was linked to most eating behavior phenotypes (e.g., emotional eating and restrained eating), but only punishment sensitivity was primarily correlated with eating pathology. Reward sensitivity was the main factor linked with reactivity to food stimuli on many behavioral measures. The neurobiological personality factors of RST offer parsimonious concepts to understand eating behavior outcomes and the differential relationships observed are useful to translational research.
