Context

The illicit use of prescription or injection drugs is extremely prevalent among opiate substitution therapy (OST) clients, and is linked to disability, morbidity, and mortality. Members of this Node have previously demonstrated that personality factors, such as impulsivity, anxiety sensitivity, hopelessness and sensation seeking are robustly implicated risk for substance misuse and related harm.  Dr. Stewart’s team recently demonstrated associations between these personality traits and substance misuse in OST clients. Indeed, a randomized controlled trial (RCT) completed in a Halifax low threshold OST clinic revealed that certain personality traits are also influential in severe addiction cases.

For example, anxiety sensitivity (AS) predicted the recent misuse of prescription opiates in an attempt to self-medicate, while impulsivity (IMP) predicted recent injection drug use associated with high-risk injection behaviours. In RCTs, brief coping skills interventions with AS and IMP individuals effectively reduced substance abuse, anxiety symptoms, and criminal behaviours. However, these brief interventions have yet to be tested in patients maintained on OST. We expect that these interventions will become a useful harm reduction tool for this population.

The main objective of this two-step CRISM – Quebec-Atlantic demonstration project is to assess the feasibility of adapting brief personality-targeted coping skills interventions to address polysubstance misuse amongst OST clients. The participants are being recruited from two provincial jurisdictions (Nova Scotia and Quebec) in a total of 4 different clinics (2 in Halifax; 2 in Montreal). During step 1, relevant information will be gathered and analyzed to allow the effective adaptation of an existing intervention plan to use with OST clients. During step 2, the intervention manuals will be adapted based on information obtained from step 1 and the feasibility of the interventions with OST clients will be assessed.
