Description of intervention(s) / exposure
Cognitive Orientation to daily Occupational Performance ApproachTM (CO-OP) was developed to support motor skill development of children with motor difficulties. CO-OP is a highly individualised client-centred program based on participant goals and uses a performance-based, problem solving, approach that enables skill acquisition through a process of strategy use and guided discovery; this strategy allows for generalisation and transfer of skills to other tasks (Mandich & Polatajko, 2004; Missiuna, Mandich, Polatajko, & Malloy-Miller, 2001; Polatajko, Mandich, Miller, & Macnab, 2001; Polatajko, Mandich, Missiuna, et al., 2001).

The CO-OP program is a 10-week block, comprising the initial goal setting session (treatment and control groups, ~2 hours), eight weeks of one hour CO-OP sessions, and a final 10th session (~1 hour) to assess outcomes (treatment and control groups).

During the eight-week therapy component of the program, children will attend a one-hour session each week in which a global cognitive strategy (goal, plan, do, check) will be utilised to support their learning of their chosen goals (three goals will be worked on throughout the program). Session attendance will be recorded and clinical notes recorded about the session. The program has a focus on guided discovery, enabling principles (fun, promoting learning, working towards independence), and parent involvement. The program will be delivered by CO-OP trained research therapists and the CO-OP trained members of the occupational therapy team at CliniKids.

The intervention sessions will include a welcome for the child and parent/guardian, and a general check in with child and parent/guardian. Following the welcome, approximately 20 minutes will be spent on each of the three goals. For each goal, the child, with assistance from the attending parent, will summarise what they have worked on at home, review the CO-OP plan trialled at home, and carry out the task. The clinician will use guided discovery to observe and support the child to develop a new plan if required and discuss and review Goal-Plan-Do-Check. At the end of each goal, the child and clinician will complete the home practice sheet with ideas for activities to perform at home between the intervention sessions. Children will be asked to practice their goals around 3-4 times per week at home.

Behaviour
Comparator / control treatment
Participants in the waitlist control group will not receive any intervention by the trial therapists during the initial 10 week block before completing their follow-up assessment. Following this wait period, they will undertake CO-OP therapy and then complete a final assessment session.
Both groups can continue to access any clinical services that they would usually access.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment will involve contacting the holder of the allocation schedule who is "off-site" after consent and eligibility (Session 1) has been completed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be performed with block randomisation using a variable block size (2 or 4), stratified by each of the clinician. Randomisation for each participant will occur offsite by a biostatistics team after completion of the intake assessment.
Masking / blinding

Efficacy
Statistical methods / analysis
This is the first study to assess to effectiveness of CO-OP for children with autism; previously only case studies have been undertaken. As such, a sample size of 30 has been selected for this study to assess the acceptability and efficacy of the intervention approach.

For the primary outcome (COPM), performance and satisfaction scores from those in the treatment group will be compared to control/treatment as usual condition at equivalent post-treatment timepoints using a mixed ANOVA design.

For the primary outcome (PQRS), scores from those in the treatment group will be compared to control/treatment as usual condition at equivalent post-treatment timepoints using a mixed ANOVA design.
