The metacognitive model of psychological disorders highlights that emotional distress is maintained by metacognitive strategies, which are related to underlying metacognitive beliefs. Considerable empirical evidence has supported the role of metacognitions in psychopathology, but few studies have examined the suggested links between metacognitive beliefs, metacognitive strategies, and symptoms within individuals. Within-person effects provide better empirical tests of theory-based hypotheses derived from clinical models as they relate to change at the individual level. Thus, the current study sought to test central predictions from the metacognitive model at the within-person level using Dynamic Structural Equation Modelling (DSEM). A sample of 222 participants gathered at convenience participated in a 26-day long assessment period where they reported daily measures of metacognitive beliefs, metacognitive strategies, and negative affect. Temporal precedence and bidirectional relations between the variables, and the possible day-to-day and within days mediation role of metacognitive strategies between metacognitive beliefs and negative affect, were tested. When controlling for previous days effects, metacognitions and negative affect (but not metacognitive strategies) predicted each other the next day, showing a reciprocal relationship. However, metacognitive strategies were significant mediators between metacognitions and negative affect within days and day-to-day. Implications and future directions based on these findings are discussed.
Social anxiety disorder (SAD) is highly prevalent with significant lifetime impacts, especially when left untreated. Cognitive behavioral therapy is the current gold standard treatment with successful patient outcomes. Cognitive behavioral group therapy (CBGT) is one form that provides unique benefits to participants including normalization of symptoms and social support, as well as providing increased access to treatment at a lower per-session cost. Research on this mode of treatment has been ongoing for over 20 years, but we still have much to learn about its overall efficacy. The goals of this critical review were to summarize and evaluate the most current research, including an analysis of the overall methodological design quality, and provide recommendations for the enhancement of future studies based on best practices. Recent studies included some best practice design elements used in measuring efficacy such as the use of comparison groups, masking procedures, fidelity assessments, and consideration of clinical significance in outcomes. However, many gaps exist such as a lack of consensus around measures and therapy manuals, as well as baseline competencies of facilitators. Future studies should consider incorporating additional best practice elements aligning with study goals to strengthen designs and provide the field with even more confidence in this mode of treatment.
