Resumo
O estudo presente tem o objetivo de efetuar uma pré-validação do ambiente de realidade virtual criado por Gamito et al (2014) como potencial ferramenta de Cue-Exposure Therapy, de modo a justificar uma validação futura com uma amostra maior. A título experimental foram propostos 3 testes neuropsicológicos como preditores do processo de extinção (Stroop, Toulouse-Pierron, Digit Span). O ambiente indutor de craving a tabaco foi apresentado a 7 fumadores ativos ao longo de 4 sessões. Este processo teve o objetivo de induzir um decréscimo no cue-induced craving, no background craving e comportamento de consumo tabágico. Não foi encontrada qualquer correlação entre funções neuropsicológicas e o decréscimo de cue-induced craving. Verificou-se que um processo de extinção não significativo pode ter contribuído para uma redução significativa do background craving, e que este decréscimo é refletido na cessação tabágica de 14.3% dos participantes. Este estudo preliminar será útil na construção de um estudo follow up mais completo, identificando variáveis a excluir, assim como aspetos importantes a incluir. A nosso ver, o contributo mais relevante do estudo presente consiste na descoberta da potencial eficácia superior do ambiente de Gamito et al (2014) na cue-exposure therapy de fumadores sociais.
The present study aims to perform a pre-validation of a virtual reality environment created by Gamito et al (2014) as a potential tool of Cue-Exposure Therapy, in order to justify a future validation with a larger sample size. Three neuropsychological tests were proposed as experimental predictors of the extinction process (Stroop, Toulouse-Pierron, Digit Span). The tobacco craving-inducing environment was presented to 7 active smokers over 4 sessions. This process aimed to produce a decrease in cue-induced craving, background craving and smoking behavior. No correlation was found between neuropsychological functions and the decrease in cue-induced craving. It was found that a non-significant extinction process may have contributed to a significant reduction of background craving, and that this decrease is reflected in the smoking cessation of 14.3% of participants. This preliminary study will be useful in the construction of a more complete follow-up study, having identified variables to be excluded, as well as important aspects to include. In our opinion, the most relevant contribution of the present study is the discovery of the potential superior efficacy of the environment of Gamito et al (2014) in the cue-exposure therapy of social smokers.
