Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intensive psychosocial intervention minus antipsychotic medication. Participants randomised to this intervention will be administered placebo tablets. The psychosocial intervention consists of four modules: intensive case management (engagement, problem solving, advocacy and support); close monitoring and crisis response; cognitive-behaviour therapy for symptoms; family support and education. The intensive psychosocial intervention will consist of twice-weekly contact with the treating team during the first 2 months of the study, and weekly contact after the first 2 months. In total, the treatment will be provided for 6 months. Placebo medication will be titrated in 1mg increments at the discretion of the treating clinician over a four-week period, until a maximum maintenance dose of 6mg/day is reached, if required. Dose will be held at 2mg/day if adequate response is observed within 4 weeks. The medication will be packaged to allow flexible dosing.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A psychiatrist, case manager and research assistant will determine if the subject is eligible for inclusion in the trial. Allocation will be concealed by contacting the holder of the allocation schedule who is "off-site".
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A stratified randomisation design will be used to allocate subjects to either one of the treatment groups. It has been established that duration of untreated psychosis and gender are associated with functional outcome, the key outcome measure in this study. Hence, we will be using characteristics as stratifying factors in the randomisation, since any chance imbalances on these prognostic variables may bias the analysis. Duration of untreated psychosis will be included as a three-level factor; < 1 month; 1 month to < 3 months, 3 months to 6 months. Along with gender, this will result in six separate randomisation lists from which subjects will be drawn. Subjects will be allocated to either one of the treatment groups using randomly permuted blocks within each stratum, to ensure that subject allocation to the treatment groups is approximately equal.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
This study commenced in 2007, when data sharing was less common, and participants were not asked to give consent to data sharing. Thus it is not considered ethical to share individual participant data when informed consent has not been obtained.
