Study type
Description of intervention(s) / exposure
The GAD-Specific Intervention will include CBT anxiety management strategies including: Psychoeducation, relaxation training, recognition of the physiological symptoms of anxiety and GAD, and various cognitive strategies specific to GAD. Within the treatment program parents will also receive education in the strategies being taught to their child, Psychoeducation regarding anxiety disorders and GAD and the role of parent behaviours in the development and maintenance of child anxiety. The program will be delivered by trained provisional psychologists. The intervention will require the child and one or more of his / her parents to attend the Psychology Clinic for 10 weekly, one-hour sessions as well as two booster sessions conducted one month and three months after completion of the initial program. The booster sessions will focus on revisiting content taught throughout the program as well as on relapse prevention. The intervention will be conducted in a group format.

Comparator / control treatment

After this point they will be offered treatment by the research team using the GAD-Specific treatment program.

Primary outcome [1] 286256 0
The primary outcome measure for this study is the diagnostic status of children using the Anxiety Disorder Interview Schedule - Child and Parent Version - ADIS-C/P (Silverman and Albano, 1996). This will be conducted by a 'blind' independent clinician.

Children's overall level of functioning will also be assessed by the clinician using the Children's Global Assessment Scale (CGAS: Shaffer et al, 1983). Values on the CGAS range from 1 to 100, where higher numbers are indicative of higher levels of functioning. In this study, scores on the CGAS will be derived based on information obtained from the ADIS-C/P interviews and will be rated by the same clinician administering the ADIS-C/P.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Children with a diagnosis of GAD will be recruited from referrals by parents, teachers, general practitioners, mental health professionals, school Guidance Officers, media publicity releases and information packages sent to schools throughout Brisbane. All referrals will be screened by telephone using a standard screening interview in order to ascertain broad inclusion criteria. Following informed consent, the child and a parent (preferably the primary caregiver) will complete a structured face-to-face diagnostic interview to determine clinical status. Following assessment and after the family has been deemed eligible to participate, the family will be randomly allocated to either the treatment condition or the waitlist control condition via a computer generated random number sequence. Random allocation will occur in advance and all families will be informed of their condition by the primary researcher. The clinician who makes a judgment regarding acceptance into the program will not be aware of the condition to which the client would subsequently be allocated to, thus allocation will be concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated random number sequence will be used for allocation of participants to one of two conditions.

Brief summary
The primary aim of this study will be to conduct a small trial to test the effectiveness of a GAD-specific program with a group of children suffering from GAD, by comparing a treatment group with a wait-list control group. It is hypothesised that children in the active treatment condition, will demonstrate significantly greater reductions from pre-treatment to post-treatment in primary GAD diagnostic status, self and parent-reported anxiety, overall global functioning.
