Anxiety disorders are among the most common, debilitating forms of childhood psychopathology, affecting 8.3-27.0% of youth before the age of 18. Child anxiety increases risk for psychiatric comorbidities across the lifespan) creates significant burdens for caregivers, and carries societal costs. Although numerous interventions have been developed to treat youth anxiety disorders, up to 82.2% of US youth with anxiety will not receive adequate care. Several reasons may explain this discrepancy, including the length and cost of existing evidence-based interventions (EBIs) and limited accessibility for families in need.

Single-session interventions (SSIs) may offer one potential solution to this gap in care. SSIs include core components of comprehensive EBIs delivered succinctly to improve the odds of access and completion. In a recent meta-analysis of 50 RCTs, SSIs reduced youth mental health problems of multiple disorders, with SSIs targeting child anxiety producing the largest effects (mean g = 0.58). Thus, well-targeted SSIs may offer cost-effective additions or alternatives to traditional care for anxiety in youth. However, most existing SSIs for child anxiety target populations already experiencing clinical distress, and a need remains for options that may prevent anxiety in vulnerable children. Given that family factors play a crucial role in the etiology of child anxiety, SSIs targeting parents and their interactions with offspring offer a novel approach to preventing youth anxiety. Thus, the aim of this project is to test the acceptability and short-term effects of a novel, web-based SSI targeting parental accommodation: a well-established, potentially modifiable risk factor for child anxiety. Results may reveal a promising, targeted approach to scalable child anxiety prevention.

Parental Accommodation as a Modifiable Intervention Target. Parent accommodation refers to changes in caregiver behaviors that facilitate or maintain their child's avoidance or anxiety. Examples include modifying family routines (i.e., staying home from work to alleviate a child's fear of separating) or directly participating in a child's avoidance strategies (i.e., keeping a child home from school). Parent accommodation reduces immediate distress but maintains long-term avoidance of feared stimuli or situations and high levels of parent accommodation are associated with anxiety problems in offspring. Parent accommodation is further maintained by caregiver factors, including parental anxiety and tolerance for distress. For instance, accommodation is greater among parents reporting higher distress about their child's anxiety symptoms and perceptions that anxiety exposure is harmful for youth.

Research shows that parent accommodation can be systematically reduced via psychosocial intervention, and interventions targeting accommodation have helped mitigate child anxiety. Translating core components of existing interventions that target parental accommodation into briefer, self-administered SSIs (i.e., those that do not involve a trained therapist) may improve families' access to empirically-driven supports for child anxiety. It may also enhance the implementation of mental health interventions by lay providers who frequently interact with children (e.g. teachers and pediatricians). Thus, the goal of this project is to test a web-based, self-guided SSI targeting parental accommodation. Parent participants will be randomized to either (a) Online Resources and Referrals (ORR) + parent accommodation SSI, or (b) ORR alone and delayed SSI access. We predict that parents will report larger declines in accommodation in the ORR+Accommodation SSI group, relative to the ORR + delayed SSI access group, from baseline to 2-week follow-up. We also predict that parents will perceive significant pre-to immediate-post-SSI increases in their ability to help their child manage distressing situations. Finally, we predict that participants will find the SSI to be acceptable.
