Description of intervention(s) / exposure
Integrating mentalization principles into cognitive behavioural treatment for childhood anxiety disorders.
The integrated therapeutic intervention consists of 7 online therapy sessions delivered by supervised clinical psychology university students to parents (with their child attending three of the 7 sessions) over a 12 week period. This includes access to the program website and intervention materials designed specifically for this study. The website includes psychoeducation, worksheets on child anxiety, parent-focused cognitive behavioural therapy skills, reflective parenting, promoting independence, attachment and graded exposure. Sessions occur for approximately 1 hour weekly or fortnightly from the participants home via telehealth. Compliance checklist have been designed for the clinicians to complete each week, which cover each of the sessions materials and interventions to monitor adherence.

Efficacy
Statistical methods / analysis
The study should have adequate power with a sample size of around 15 – 20 participants. Clinical studies in mental health using a single group design tend to display large effect sizes (Cohen, 1988: Peters et al., 2021).
- Descriptive statistics including age and sex of the child, principal and secondary diagnoses and subscale and total scores on each measure at pre, post and follow up intervention phase will be generated and evaluated (including means and standard deviations).
- Missing data at pre or post intervention phases will be managed by multiple imputation methods (expectation maximisation) (Ng, 2013).
- Intervention efficacy will be assessed using one way, within subjects, repeated measures ANOVA, with the independent variable being time. Violation of assumptions will be reviewed and discussed and post-hoc Bonferroni adjustments will be conducted to highlight any group differences. Effect size will be calculated using Omega squared (Olejink & Algina, 2003).
- Further analysis will include reliable change (Jacobson and Traux, 1991) and clinically significant change (Jacobson, Follete, and Revenstof, 1984) indexes.
- Feasibility and acceptability analysis of the intervention will be conducted using retention and dropout rates and item responses from questionnaires.
