Affective Modulation of Positivity for Alcohol Use Disorder

Study Overview
=================
Brief Summary
-----------------
The proposed study is a pilot study examining the feasibility and potential utility of administering a psychosocial intervention termed Affective Modulation of Positivity (AMP) for individuals suffering from co-morbid depression or anxiety disorders and alcohol use disorder (AMP-A). The aims of this study are to (1) determine the feasibility and potential utility of administering AMP-A with individuals suffering from alcohol use disorders, (2) explore the potential impact of training on positive and negative affect, symptom severity, and functional disability, and (3) explore the potential impact of training on neural reactivity to reward and alcohol cues during functional magnetic resonance imaging (fMRI).

Detailed Description
-----------------
This study is a non-randomized, single-arm, single-site clinical trial conducted at Laureate Institute for Brain Research (LIBR) in Tulsa, OK. The primary objective for this study is to examine the feasibility and acceptability of conducting positive affect training with individuals suffering from substance use disorder. Primary outcome will include treatment completion rate; secondary outcome will include the score on a participant feedback questionnaire. The investigators hypothesize that the majority of participants (>60%) will complete all 11 sessions of the intervention and that participant feedback concerning the intervention will be at least moderately favorable on average.The secondary objective(s) is to explore the potential impact of training on positive and negative affect, symptom severity, and functional disability. The investigators hypothesize that positive affect will significantly increase from baseline to post-intervention, while negative affect, alcohol-related craving, and functional disability will significantly decrease. A tertiary objective is to explore the potential impact of training on behavioral and neural responses involving the processing of positively valenced or alcohol-related cues. The investigators hypothesize that activation with striatal and orbitofrontal cortex (OFC) regions to alcohol-UNrelated reward cues will increase from baseline to post-intervention, while striatal and OFC response to alcohol-related cues will decrease from baseline to post-intervention. Participants will be asked to complete interview and pencil-and-paper questionnaires related to clinical symptoms, traits and personality characteristics, daily life function, and medical and mental health history at both pre- and post-intervention. Participants will also be asked to complete brief follow-up survey sessions 3 months after completing treatment. If there are participants who are only able to complete part of the intervention (i.e., only able to attend a few of the sessions) either due to their own wish to terminate or due to exclusion criteria or clinical concerns, they will only be asked to complete survey sessions for weeks that they attend. Neuroimaging procedures will be conducted at both pre- and post-intervention. Each neuroimaging session will last approximately 1.5-2.5 hours and will involve completion of self-report measures regarding current affective state and sleepiness and a functional MRI session during which participants will complete tasks related to reward processing and alcohol cue reactivity. Following completion of baseline assessments, participants will be asked to complete 11 sessions of the positive affect intervention, conducted once or twice weekly and with each session lasting 1 - 1.5 hours. If the content of sessions is too much to cover for any one client, the intervention may be extended to 13 sessions as needed. Participants will be expected to complete all intervention sessions within 16 weeks of starting the first session. Each session will be completed as individual therapy sessions (i.e., one-on-one with a therapist). The positive affect intervention will involving positive emotion enhancement exercises established in prior studies, including noticing and amplifying positive emotions, practicing gratitude, engaging in acts of kindness, and pleasurable or meaningful activities, identifying strengths and values, being optimistic, engaging in activities meant to make others happy, and living life to its fullest. The investigators will use the protocol developed by Taylor et al. with modifications to specifically address alcohol use, based on previous work. The general structure of each session will follow standard cognitive behavioral treatment regimens as follows: (1) meet with clinician to review completion of the prior week's exercises, including self-monitoring forms of emotions and exercise completion; (2) identify and troubleshoot any issues that arose during exercise completion; (3) introduce material about a new positive emotion enhancement activity; (4) identify concrete exercises to implement for the upcoming week.

An individual who meets any of the following criteria will be excluded from participation in this study: Unwillingness or inability to complete any of the major aspects of the study protocol, including self-report or behavioral assessment. However, failing to complete some individual aspects of these assessment sessions will be acceptable (i.e., being unwilling to answer individual items on some questionnaires or being unwilling to complete a behavioral task).

Has a history of unstable liver or renal insufficiency; glaucoma; significant and unstable cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurologic, hematologic, rheumatologic, or metabolic disturbance; or any other condition that, in the opinion of the investigator, would make participation not be in the best interest (e.g., compromise the well-being) of the subject or that could prevent, limit, or confound the protocol-specified assessments. A positive test for drugs of abuse, including alcohol (breath test), cocaine, marijuana, opiates, amphetamines, methamphetamines, phencyclidine, benzodiazepines, barbiturates, methadone, and oxycodone at the time of baseline assessments. Participants will be asked to refrain from using alcohol within 24 hours prior to assessment sessions and to refrain from using marijuana within 48 hours of assessment sessions. Current use of a medication or change in the dose or prescription of a medication within the 6 weeks prior to enrolling in the study that could potentially affect brain functioning (e.g., stimulants, anxiolytics, antipsychotics, mood stabilizers, anti-hypertensives). The current use of antidepressants (i.e., SSRIs) will not be excluded as long as the dose has remained consistent for 6 weeks prior to baseline assessment sessions. While individuals reporting use of benzodiazepines will be excluded; individuals with sporadic use (i.e., less than once per week) may be included, but will be asked to refrain from using within 72 hours prior to assessment sessions. Inclusion of individuals reporting other types of medications or supplements not listed or considered this far will be at the discretion of the PI according to evidence in the literature of it affecting brain function or brain blood flow. Taking drugs that affect the fMRI hemodynamic response (e.g., methylphenidate, acetazolamide, and excessive caffeine intake > 1000 mg/day). Concurrent engagement in psychosocial treatments that specifically target alcohol use disorder or mood/anxiety symptoms and began within 12 weeks of baseline assessments. Individuals concurrently receiving psychosocial treatments for other symptoms, or that are not specifically targeting symptoms (e.g., ongoing support groups) will not be excluded as long as the dose of treatment (i.e., frequency of sessions) has not changed significantly within 6 weeks prior to enrolling in the study.
