Evaluación de los sesgos atencionales en fumadores a través de las etapas del modelo transteórico

Abstract

Transtheoretical Model of Change" of Prochaska and DiClemente is one of the most widely used models to explain the intentional behavioral change, especially in the addictive behaviour.On the other hand, there is evidence that cognitive biases exert any influence on the addictive behavior. In this frame, we ask whether a model of change, whose main variables are kind of psychological constructs, could be assessed experimentally from the information processing.Specifically, we wonder if biases attentionals and memory exert a differential action depending on the stage of Transtheoretical Mode. We have used the tasks: emotional Stroop, dot probe task, recognition and self-remembrance. Another objetive, we have considered the constructs of MTT in the model itself and compare the results with those found in a standard classification based on consumption variables (WHO). The addictive behavior chosen for the evaluation has been the consumption of snuff, because of the negative implications for the healthy behavior. We have obtained empirical support for the MTT and partial support of cognitive biases according to stages of MTT.
