Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants from a larger validation study of mental health screening questionnaires will also be able to opt in to a low-intensity randomised controlled trial providing feedback about their symptoms. In the trial, participants will get feedback about their symptoms (intervention condition) or general feedback about symptoms in the population (control condition). This feedback will be for either depression symptoms, adult ADHD, or social phobia, depending on which screener is presented in the larger validation study. The feedback will be provided to the participants in the intervention online on a single screen. Prior to the feedback, participants will complete a brief set of questions on quality of life and service use. Following the feedback, participants will then complete another brief survey 3 months later. Respondents who choose to participate in the trial will only be identifiable through their provision of an email address.

Participants will be able to opt-in for participation in the study after completing a large survey of mental health screening questionnaires. Allocation will be concealed by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (within limesurvey).

Efficacy
Statistical methods / analysis
In the Australian general population 11.9% of people seek help for a mental disorder in a 12-month period. However, 20% meet criteria for a disorder and substantially more have mental health problems. The feedback intervention aims to reduce the service gap by 30%, i.e., increase overall helpseeking from 11.9% to 15.5%. To find such a difference with 85% power, we will require 3372 participants (1686 in each condition across the three disorders of interest). The study will also have 90% power to find small differences (d > 0.10) in help seeking intentions between intervention and control groups overall, and to find small differences (d > 0.17) between intervention and control groups within the three disorders of interest.

Binary mixed effects repeated measures models will be used to analyse the help seeking outcomes, following an intention to treat approach under the missing at random assumption.
