Prediction of Cognitive Flexibility in Methadone-Treated Patients based on Meta-Worry, Anxiety, and Duration and Amount of Methadone Use

The aim of this study was to predict cognitive flexibility based on meta-­worry, anxiety, duration and dose of methadone use.
The current research was a descriptive-correlational one. The statistical population of this study included all male drug-dependents who were under methadone treatment in Qazvin in 2016. From among this population, 254 participants were selected via purposive sampling method and completed Wells's Meta-Worry Questionnaire (2005), Beck Anxiety Inventory (1988), and Dennis and Vander Wal's Cognitive Flexibility Inventory (2010).
The results of step-wise multivariate regression method showed that meta-­worry and anxiety significantly predicted cognitive flexibility in men under methadone treatment (p 0/05).
It can be concluded that meta-worry and anxiety have a negative significant correlation with cognitive flexibility. In this way, the high levels of meta-worry anxiety lead to low cognitive flexibility. Therefore, it is necessary to focus on metacognitive components for achieving high cognitive flexibility; in addition drug addicts under methadone maintenance treatment are recommended to use metacognitive therapy.
