Self-Help Parent Training for Conduct Problems in Children

Inclusion Criteria: Families on waiting lists and child and adolescent mental health services clinics with children aged 2-5. Scores in the clinical range on a standardised measure of child behaviour problems. At least one parent in each family must be literate, fluent English speakers to participate because the self-administered intervention will primarily consist of written instructions and information in English. Exclusion Criteria: Clients whose children score below a clinical cut-off score on a standardised measure of child behaviour problems. This is to ensure that participants are appropriate for an intervention aiming to reduce behaviour problems. Non-English speakers or those who are unable to read cannot be included because reading English is required to complete the self-administered intervention. Children or parents with severe disabilities and children with a developmental disorder (e.g., autism) will be excluded because the version of the parent training programme that will be implemented is not designed for families with these types of problems. Children who live with a temporary caregiver will be excluded because the intervention is designed for full-time parents and follow-up will be after one year. Children or parents who are currently receiving treatment for psychological problems will be excluded because outcomes may be influenced by interventions not affiliated with this project.
