Abstract :
Introduction: Acceptance and commitment and metacognitive therapies are considered as third wave
therapies. This study aimed to compare the effectiveness of acceptance and commitment therapy (ACT) and
Metacognitive therapy (MCT) on the mind-wandering index in adolescents.
Methods: In a randomized clinical trial, 45 female adolescents in Karaj were estimated using a Cloninger
sample volume estimation method and were selected through purposive screening sampling. They were
randomly assigned into three groups. Two ACT and MCT were presented to the experimental groups in the
form of ten sessions of 1 hour. The data were collected at three time intervals through a demographic
checklist, a structured clinical interview and a mind-wandering questionnaire. Analysis of covariance and
Bonferroni analysis tests were used.
Results: The primary outcomes showed that both ACT and MCT had a significant effect on the mindwandering index (p<0.01), although this effectiveness was more favorable in the MCT group (P<0.05). The
secondary outcomes also showed the stability of the results in the follow-up stage (p<0.05).
Conclusion: The results of this study suggest the effectiveness of third wave therapies on psychological
indices. These findings can be combined with clinical applications in planning new therapeutic and
educational perspectives.
