Evidence Base Update on the Treatment of Early Childhood Anxiety and Related Problems

The controlled evaluation of treatments for early childhood anxiety and related problems has been a relatively recent area of investigation, and accordingly, trials examining early childhood anxiety treatment have not been well represented in existing systematic reviews of youth anxiety treatments. This Evidence Base Update provides the first systematic review of evidence supporting interventions specifically for the treatment of early childhood anxiety and related problems. Thirty articles testing 38 treatments in samples with mean age < 7.9 years (N = 2,228 children) met inclusion criteria. We applied Southam-Gerow and Prinstein's (2014) review criteria, which classifies families of treatments according to one of five levels of empirical support-Well-Established, Probably Efficacious, Possibly Efficacious, Experimental, and of Questionable Efficacy. We found family-based cognitive-behavioral therapy (CBT) to be a Well-Established treatment, and Group Parent CBT and Group Parent CBT + Group Child CBT to both be Probably Efficacious treatments. In contrast, play therapy and attachment-based therapy are still only Experimental treatments for early childhood anxiety, relaxation training has Questionable Efficacy, and there is no evidence to date to speak to the efficacy of individual child CBT and/or medication in younger anxious children. All 3 currently supported interventions for early childhood anxiety entail exposure-based CBT with significant parental involvement. This conclusion meaningfully differs from conclusions for treating anxiety in older childhood that highlight the well-established efficacy of individual child CBT and/or medication and that question whether parental involvement in treatment enhances outcomes.
