Background: Research has identified cognitive behavioral therapy with exposures (CBT) as an effective treatment for youth anxiety. However, despite implementation efforts, few anxious youth receive CBT. Direct-to-consumer marketing offers a different approach to address unmet need for effective. Involving a local caregiver key opinion leader to direct-to-consumer initiatives may be an effective strategy to increase caregiver demand for CBT. Research indicates that key opinion leaders improve health promotion campaigns, but key opinion leaders have not been studied in the context of increasing caregiver demand for evidence-based treatments.Method: Project CHAT (Caregivers Hearing about Anxiety Treatments) will test the role of key opinion leader participation in conducting outreach presentations to increase caregiver desire to seek EBPs for their youth’s anxiety. Caregiver attendees (N = 180) will be cluster-randomized by school to receive one of two different approaches for presentations on EBPs for youth anxiety. Both approaches will involve community outreach presentations providing information about (a) youth anxiety, (b) effective treatments for youth anxiety, and (c) seeking CBT for youth anxiety. The researcher-only condition will be co-facilitated by two researchers. In the key opinion leader condition, a caregiver key opinion leader from each local community will be involved in tailoring the content of the presentation to the context of the community, co-facilitating the presentation with a researcher, and endorsing strategies in the presentation that they have found to be helpful. In line with the theory of planned behavior, caregiver attendees will complete measures assessing their knowledge of, attitudes towards, perceived subjective norms about, and intention to seek CBT pre- and post-presentation; they will indicate whether they sought CBT for their youth at a three-month follow-up. Results will be analyzed using a mixed method approach to assess the effectiveness of a key opinion leader to increase caregiver demand for CBT.Discussion: This study will be the first to examine the potential of key opinion leaders to increase caregiver demand for CBT. If proven effective, the use of key opinion leaders could serve as a scalable dissemination strategy to increase the reach of evidence-based treatments. Trial registration: This trial was registered on clinicaltrials.gov (NCT04929262) on June 18, 2021. At the time of trial registration, pre/post presentation data had been collected from 17 participants; thus, it was retrospectively registered.
