Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study is an open-label pilot trial including a qualitative and quantitative intervention evaluation. The intervention provided to participants (parent-child dyad) is a 10-week face-to-face cognitive behaviour therapy. Ten separate but concurrent parent and child treatment sessions will be provided in an individual format. One, 1 hour treatment session will occur each week, over 10 weeks. Treatment sessions will include relevant psychological education and the development of skills to best treat emotional symptoms. Treatment related homework tasks are expected to be completed in-between treatment sessions. Homework tasks are designed specifically based on the participants needs. Parent-child dyads will also be invited to participate in a qualitative interview following completion of the intervention to assess treatment acceptability. An additional treatment interested group will be interviewed to evaluate prospective acceptability.
The intervention and qualitative interviews will be delivered by doctoral-level students (provisional psychologists), with oversight from registered clinical psychologist with extensive experience in clinical practice and research. The intervention will be delivered at a university based psychology clinic. Qualitative interviews will be conducted online via a video-conferencing platform.

Summary
Brief summary
The purpose of this study is to determine the acceptability and effectiveness of a newly developed parent-child cognitive behaviour therapy protocol for parents and their children who both have an anxiety disorder diagnosis. Ten separate parent and child group treatment sessions will be delivered. Treatment sessions will include relevant psychological education and the development of skills to best treat anxiety symptoms. It is anticipated that parent and child participants will find the treatment acceptable and show improvement in symptoms from pre-treatment to post-treatment. Findings from this study are expected to advance current understanding of effective treatment for parents and children with anxiety.
