Parent-led cognitive behavioural therapy for child anxiety disorders have garnered a growing evidence base. However, it is unclear how such approaches translate into routine clinical practice. The current study aims to evaluate the effectiveness of an 8-session treatment (From Timid to Tiger) in reducing child anxiety and behavioural difficulties, as well as family accommodation. The parents of 71 children (aged 4-11) were assigned to the treatment or a waitlist control. Parent report measures were completed pre-treatment, at treatment-end, and at 3-month follow-up. Parents assigned to the waitlist were assessed 8 weeks after the initial assessment. Findings indicated that parents who attended the group reported significant reductions in child anxiety and behavioural difficulties. In addition, the parents in the treatment group reported a reduction in family accommodation compared to those in the waitlist. The current control trial provides tentative evidence of the use and effectiveness of such parent-led approaches in addressing child anxiety difficulties commonly seen in routine clinical practice. PRACTITIONER POINTS: Parent-led approaches are effective treatments in managing child anxiety difficulties. Very little research to date has assessed the effectiveness of such approaches in routine clinical practice. The From Timid to Tiger program is a brief parent-led CBT intervention. The programme was effective in reducing child anxiety and behavioural difficulties. Parents also reported a reduction in behaviours related to family accommodation. Such programmes show promise and can be used in routine clinical practice.
