Substance Abuse clinical trials at UCSD

The purpose of this study is to examine the feasibility of a protocol in which individuals with comorbid depression or anxiety disorders and alcohol use disorder will be randomized to complete Amplification of Positivity for Alcohol Use Disorder (AMP-A)- a psychological treatment focused on increasing positive thoughts, emotions, and behaviors- or a traditional cognitive-behavioral therapy (CBT) intervention. Assessed outcomes will include participant acceptability and completion rates, participant compliance with the intervention, positive and negative affect, substance use- and depression and anxiety-related symptom severity, and functional disability.

The goal of this clinical trial is to learn if receiving Prolonged Exposure Therapy for PTSD in massed format (multiple sessions weekly) is as effective as receiving it with sessions once per week among veterans with PTSD and substance use disorder in intensive outpatient substance use treatment. The main questions it aims to answer are: - Will the massed format help participants complete and benefit from Prolonged Exposure in terms of PTSD symptoms? - Will it help participants reduce substance use? Participants who are in intensive substance use treatment will be asked to complete Prolonged Exposure with either weekly sessions or multiple sessions per week.

Many people who have posttraumatic stress disorder (PTSD) also struggle with problematic alcohol or drug use (substance use disorders [SUD]). Patients with both conditions prefer PTSD be treated alongside SUD. However, clinicians don't know if treatments that have been found to help those with PTSD work as well for people who also have SUD. This often leads to delaying PTSD treatment or using psychotherapies without research support. Trauma-focused psychotherapy (TFT) is the type of psychotherapy for PTSD that has been studied most often among people with both PTSD and SUD. It reduces symptoms of PTSD and substance use, although it might not work as well in those who have SUD as those who do not. Further, many patients with both PTSD and SUD do not complete TFT. Another strategy for treating PTSD is non-trauma-focused psychotherapy (NTFT). One NTFT, Present Centered Therapy, has been found to reduce symptoms of PTSD and more patients are able to complete NTFT than are able to finish TFT. However, no one has studied how well Present Centered Therapy works among patients who also have SUD. We will test which approach (TFT of NTFT) is better for reducing symptoms of PTSD and which is more likely to be completed by patients with both PTSD and SUD at VA healthcare facilities. We will also test to see whether some participants did better than others, so we can learn how to individualize treatment recommendations to patients. Participants will be assigned by chance to either TFT of NTFT. Patients assigned to TFT will receive either Prolonged Exposure or Cognitive Processing Therapy; both are weekly psychotherapies focused on addressing thoughts and/or memories related to their trauma. Those assigned to NTFT will receive Present Centered Therapy, a weekly psychotherapy in which patients learn about how PTSD relates to their current difficulties and problem solve current life difficulties. All participants will also receive SUD treatment. Participants will answer questions about their symptoms and experience with treatment before, right after they finish, and three and six months after they finish PTSD treatment. At the end of the study we will compare which treatment approach worked better to decrease PTSD symptom severity and which treatment patients were better able to complete. We will also track other outcomes that are important to patients (e.g., how they are doing in their relationships).
