Psychotherapy for Psychosis, Adverse Events, & Substance Misuse

Status Completed

Clinical Trial Summary

People with psychosis have significantly higher rates of adversity (e.g., abuse) and substance misuse (i.e., problematic drug and alcohol use) than people with other mental illnesses. Research has found that adversity and substance use both negatively influence recovery from a psychotic disorder. Currently, there are few treatment options for people living with psychosis, substance misuse, and adversity-related symptoms (e.g., anxiety, depression). This is especially true for young adults who are in the first years of a psychotic illness (i.e., early phase psychosis; EPP) who may be in the best position to benefit from treatment because they have not been ill for as long as others with more chronic psychosis (i.e., >10 years). Research has demonstrated that Prolonged Exposure (PE), a psychological therapy that helps improve adversity-related symptoms, may be appropriate for people in EPP, although there is limited evidence regarding its adaptation from use in chronic psychosis to EPP. The aim of the proposed study is to adapt and optimize PE therapy for young adults in EPP. We aim to recruit 20 individuals from the Nova Scotia Early Psychosis Program (NSEPP) aged 19-35 who will participate in 15 sessions of adapted PE; we will compare their scores before and after treatment on measures of psychotic symptoms, amount and frequency of substance use, and adversity-related problems. Our goal is to target two factors that may be contributing to and maintaining negative outcomes: avoidance and hopelessness. These factors will be addressed by asking participants to face feared reminders of adversity and learn new ways to think about adverse experiences and mental health problems. The adaptation and application of this evidence-based intervention has the potential to create a new treatment avenue for EPP, reducing impairment and distress, and improving recovery rates.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
