ABSTRACT
Cognitive behavioural therapy (CBT) for childhood anxiety has shown moderate effects. However, inconsistency in findings during the last decades of treatment research and lack of measurable treatment gains over time has led to a call for optimizing interventions by identifying the active mechanisms involved and for whom such interventions are effective. It has been suggested that the moderate effects may be explained by the fact that emotion regulation rarely is directly targeted in CBT-interventions and that interventions may be more effective for children with a certain level of problems with emotion regulation. Using data from a randomized controlled trial with 160 children and their mothers at baseline (t1) and posttreatment (t2), we examined whether being randomized to CBT predicted change in anxiety symptoms from t1 to t2 and whether this change was mediated by change in emotion regulation from t1 to t2. We also investigated whether the strength of this indirect pathway depended on the level of emotion regulation problems at baseline. Latent baseline target moderated mediation analyses within a structural equation modelling framework were conducted. Results showed a significant indirect pathway between receiving CBT to improved emotion regulation, which again was significantly associated with reductions in anxiety symptoms. The findings suggest that the effect of CBT is similar for children irrespective of initial levels of emotion regulation measured broadly, whereas there was some evidence of a baseline moderation effect of the subdomain emotional control. Emotion regulation, and especially emotional control, seems to be an underlying mechanism for positive effects of CBT for anxiety disorders in children, possibly indicating that a greater emphasis on emotion regulation may optimize the intervention.

PURPOSE: Adolescence is a sensitive period for developing mental health problems. Interventions targeting emotion regulation have shown promising transdiagnostic effects for this group, but optimization efforts are called for. In the current study, we used an element-based approach to identify potentially active ingredients in interventions measuring emotion regulation, to guide further optimization. METHODS: We coded practice elements in 30 studies based on a systematic review of mental health interventions measuring emotion regulation in adolescents (N = 2,389 participants, mean age 13-17 years). Using a three-level modeling approach, we then investigated the difference in effect on emotion regulation between studies of interventions with and without these practice elements. RESULTS: We identified 75 practice elements and 15 element categories used in the included interventions. Results showed significantly stronger effects on emotion regulation when interventions included the practice elements Setting goals for treatment (difference in d = 0.40, 95% CI [0.09, 0.70], p = .012) and Psychoeducation about acceptance (difference in d = 0.58, 95% CI [0.09, 1.07], p = .021). Furthermore, a total of 11 elements and four overall categories were identified as potentially active ingredients, based on an effect size difference of > 0.20 between interventions with and without the elements. CONCLUSION: The results can direct experimental research into the selection of practices that are most likely key to mechanisms of change in interventions addressing emotion regulation for adolescents. The challenge of measuring emotion regulation is discussed.
