Validation and clinical application of the Metacognitions Questionnaire in a sample of Brazilian generalized anxiety disorder patients: the effects of different treatment interventions

Abstract Introduction Metacognitive beliefs about worry may trigger anxiety. However, the effect of generalized anxiety disorder (GAD) treatment on metacognition has not yet been investigated. Objectives To validate the Metacognitions Questionnaire (MCQ-30) in a Brazilian GAD sample and verify whether different interventions reduce metacognitive beliefs. Method We recruited 180 GAD individuals and randomized them to Body in Mind Training (BMT), Fluoxetine (FLX), or an active control group (Quality of Life [QoL]) for 8 weeks. The MCQ-30 was assessed for internal consistency, was evaluated with confirmatory and exploratory factor analyses, and was tested for convergent validity with the Penn State Worry Questionnaire (PSWQ). Generalized estimating equations (GEE) were employed to analyze differences after the interventions. Results The MCQ-30 demonstrated good internal consistency and acceptability; the original five-factor model was supported. There was a positive moderate correlation between MCQ-30 scores and worry. GEE showed a significant group x time interaction (p < 0.001). Both BMT (mean difference [MD] = -6.04, standard error [SE] = -2.39, p = 0.034) and FLX (MD = -5.78, SE = 1.91, p = 0.007) reduced MCQ-30 scores. FLX was superior to QoL, but not BMT, at weeks 5 and 8. There were no differences between BMT and QoL. Conclusion The Brazilian-Portuguese version of MCQ-30 showed good psychometric properties. Furthermore, the positive effect of FLX and BMT on metacognition suggests it may represent a potential therapeutic target.

Need for Mindfulness-based Relapse Prevention Strategies for Postpartum Smoking Relapse Prevention

The health concerns for women are varied from that of men and are of higher concern. To increase this concern, women have recorded higher smoking relapse rates than men were an alarming 60% to 90% of the women who have attempted to quit relapse within their first year. Women who quit during pregnancy are seen to have higher rates of relapse than others. Such postpartum relapse has detrimental effects on the mother as well as the newborn. Mindfulness?based interventions have seen benefits in the areas of substance abuse and relapse prevention. Although research in the area of mindfulness and its benefits on smoking cessation has been limited, literature shows positive outcomes. This brief article examines the need for mindfulness-based relapse prevention strategies for women who are undergoing postpartum smoking relapses so that they could benefit from the same.
