Brief summary

The aim of the project is to trial the use of a computerized psychological treatment for problematic cannabis use in Early Psychosis. Cannabis use is associated with an increased risk of psychosis and cannabis use is high in people presenting for treatment of first episode psychosis (FEP). Cannabis use is also associated with high relapse rates in FEP. Therefore, it is vital that Early Psychosis Treatment Centers (EPTC) address cannabis use. This project aims to trial the SHADE computerized treatment package among an FEP sample presenting to an EPTC at Bondi Junction Community Mental Health Centre and Campbelltown Community Mental Health Centre, to determine whether the addition of this resource is effective in reducing cannabis use over the treatment period.

Interventions

The computerised psychological treatment program, SHADE, comprises 10 sessions of combination cognitive behaviour therapy and motivational interviewing focussed on reducing depression and reducing/ceasing alcohol/other drug use problems (including cannabis). It is delivered either in DVD or Internet-delivered format. All participants will complete the SHADE treatment over the Internet, excepting those who do not have reliable Internet access but have access to a computer in their homes. In th

It is delivered either in DVD or Internet-delivered format. All participants will complete the SHADE treatment over the Internet, excepting those who do not have reliable Internet access but have access to a computer in their homes. In these cases, participants will be offered the SHADE treatment program delivered via DVD. Participants are asked to complete each of the 10 session one week apart, with each session taking around 45 minutes to complete. Each computerised session is supported by a therapist (by telephone) who provides a compliance check of sessions completed, encouragement to continue engagement with the program, troubleshooting barriers to completing homework tasks, and a risk assessment (approximately 15 minutes duration). Telephone-based therapist support sessions occur once weekly over the 10-week intervention period.
