A novel independence intervention to treat child anxiety: A nonconcurrent multiple baseline evaluation

Rates of child and adolescent anxiety have increased markedly over the past decade (Haidt & Twenge, 2023). Exposure-based cognitive-behavioral therapy is the gold standard in the treatment of anxious children (Hofmann et al. (2012)). However, many clinicians refrain from using exposure due to concerns about its safety, effectiveness, and ethics (Deacon et al., 2013; Whiteside et al., 2016). We propose a novel treatment approach for child anxiety composed of independence activities (IAs), which are child-directed, fun, unstructured, developmentally challenging tasks performed without parents' help. These tasks are purposely topographically unrelated to the stimuli that cause anxiety, in direct contrast to exposure therapy. Despite this dissimilarity, IAs target putative mechanisms involved in the development and maintenance of child anxiety (e.g., parental accommodation and overinvolvement, child avoidance, unhelpful thinking styles). Using a nonconcurrent multiple baseline design, this five-session treatment provided preliminary evidence of high treatment acceptability from children and parents. Medium to large improvements were reported in child anxiety and avoidance, parent and child (behavioral and cognitive) mechanisms involved in the maintenance of child anxiety, and untargeted secondary outcomes such as child happiness. Results may suggest a new treatment paradigm, which is desperately needed, given unabated increases in child and adolescent anxiety despite vast resources being directed toward the problem.
