The comparison Effectiveness of the Third Wave Behavioral Therapies on Behavioral Inhibition/Activation Systems of Anxious Football Player

One of the most important models of motivational approach and avoidance, in recent decades, is the model of behavioral activation system (BAS) and behavioral inhibition system (BIS) presented by Gray. The present study aimed at comparing the group metacognitive therapy (MCT) and group mindfulness acceptance and commitment therapy (MAC) on BAS and BIS of anxious professional football players in the U-19 league in Tehran. Participants in this study were 60 football players in professional football leagues in Tehran. These participants were entered into the assessment stage, and after obtaining informed consent, they were randomly assigned to one of the three experiment groups of MCT, MAC, and WL. The participants completed Jackson’s revised 5-scale of rewarded sensitivity theory in pretest, posttest, and three months follow-up stages. The results of the present study demonstrate that MCT and MAC can make some changes in BAS and BIS among anxious football players. MCT has been more affecting on BIS than both other groups. According to these findings, it would ensure that football players affected by anxiety can take the opportunity to gain advantages from such third-wave interventions.
