Description of intervention(s) / exposure
Parental Anxiety Management (PAM) for experimental group. This program is based on cognitive behavioural therapy, 5 x 40mins sessions delivered in a group format, once per fortnight. The treatment components included: psychoeducation, cognitive restructuring, time management, problem-solving, and gradual exposure for the parents. ALL children and families received cognitive behavioural therapy [Cool Kids treatment program (Rapee, Wignall, Hudson, and Schniering, 2000)] 10 x 2 hour sessions delivered in group format, once a week. These sessions included psychoeducation, cognitive restructuring, problem-solving, assertiveness training, and gradual exposure. Both parents and children were involved in the Cool Kids treatment program. For families randomly assigned to the PAM group, the PAM program was conducted simultaneously with the Cool Kids treatment program over the 10-week period. For families that were randomly assigned to the PAM program, the program was offered to both parents. Moreover, both anxious and non-anxious parents were randomly allocated to the PAM program.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following a brief telephone screen, parents signed consent forms at the assessment and children provided verbal assent. Children who met criteria for inclusion and agreed to participate were allocated to a group based on the child's age. Allocation was concealed: clinicians determined the child's eligibility for the study and then the clinic administration team conteacted the research officer who held the allocation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The first author used a schedule from a random number generator (computer software obtained online) to assign each group to treatment condition and to therapists.

Summary
Brief summary
Objective: The current trial examined whether the inclusion of a parental anxiety management (PAM) program in addition to family cognitive-behavioral therapy (CBT) was more efficacious than family CBT only in treating childhood anxiety disorders. Method: Two hundred and nine children (aged 6-13 years) with a principal anxiety disorder were randomly allocated to a 5 session PAM program (n = 109) in addition to family CBT or family CBT only. Results: Overall, results revealed that the addition of PAM did not significantly improve principal anxiety diagnostic outcomes for the child or the parent compared to the CBT only group at post-treatment and 6-month follow-up. Results further suggest that children with non-anxious parents were more likely to be diagnosis-free for any anxiety disorder compared to children with anxious parents at post-treatment and 6-mth follow-up. Conclusions: The present findings indicate that the addition of PAM in its current format did not lead to additional gains in diagnostic status when used as an adjunct to family CBT in the treatment of the child’s anxiety disorder. The addition of PAM did not lead to a sufficient decline in parental anxiety disorders over and above the decline observed across time for children receiving CBT. Parental anxiety status impacted on child diagnostic outcome: Children were less likely to be diagnosis-free following treatment if they had a parent who also had an anxiety disorder.
