Brief summary
Chronic drug addiction is not only associated with increased mental health symptoms, such as anxiety and depression, but also with brain (neural and cognitive) deficits. These neurocognitive deficits (NCDs) in memory, attention, decision-making, self-control and judgement disturb normal daily functioning and attempts for abstinence. These NCDs are also associated with worse long-term treatment outcomes. Current treatment programs for addiction to opioids and amphetamines are mainly focused on abstinence from illicit drugs with or without assistance of medications, with the assumption that these NCDs will subsequently heal. However, NCDs are found to persist even after a long-term abstinence and are thought to contribute to relapse, decreases quality of life, or lack of reintegration into society. Furthermore, NCDs (particularly related to attention and memory) are considered a potential obstacle for engagement in therapy services for addiction and associated mood, anxiety and trauma-related comorbidities (i.e., cognitive-behavioral therapies). Brain rehabilitation programs focused on compensatory strategies and training exercises for NCDs associated with traumatic brain injuries, stroke, multiple sclerosis and schizophrenia has consistently been found to improve functioning and long-term outcomes for these populations. There have been a few preliminary attempts to transplant cognitive rehabilitation with substance use populations, with some limited promise. However, these previous studies failed to link cognitive strategies with the drug use and affective/craving symptoms experienced by patients and also did not fully incorporate knowledge gained from neuroscientific research on opioid and/or methamphetamine addiction specifically. The aim of this study is to characterize clinical efficacy for an intervention targeting NCDs in opioid and/or methamphetamine addiction by enhancing awareness and use of neurocognitive skills in the context of substance use recovery. This aim will be accomplished by randomizing 80 subjects with opioid and/or methamphetamine use disorder who are already enrolled in substance use treatment in the state of Oklahoma to also complete a novel Neurocognitive Empowerment for Addiction Treatment (NEAT) program developed by a group of investigators at Laureate Institute for Brain Research, Tulsa, Oklahoma. NEAT will be novel in (a) its use of cartoons, brain awareness games and real-life scenarios to ensure it is interactive and engaging, (b) the focus on the role of neurocognitive deficits in recovery from substance use and co-occurring mental health symptomatology, and (c) its incorporation of neuroscientific findings specific to substance use to the training and exercise strategies. Subjects will be followed up for twelve months after starting the program with different measures for addiction and mental health recovery to explore the efficacy of NEAT compared to the control intervention. Using LIBR's cutting-edge neuroimaging facilities before and after interventions, this study has the unique opportunity to monitor not only clinical outcomes but also potential changes NEAT may have on brain structure and function. In case of finding reasonable clinical efficacy for NEAT, it will be hopefully integrated as a manualized brain rehabilitation program to the substance use treatment programs.
Interventions
BEHAVIORALNeurocognitive Empowerment for Addiction Treatment (NEAT)
NEAT will be conducted in person, in groups of 6-14, and consist of 14, 1.5-hour sessions. Each NEAT session will consist of (1) a didactic, psychoeducation portion describing the concepts and skills of focus, (2) written material with descriptions of the concepts/skills in verbal and pictorial (cartoon) formats, (3) practicing with cognitive tasks relevant for each skill, (4) discussion of how they can monitor and practice each skill in their daily life. Specifically, we will provide psychoeducation, cognitive exercises, time-management and daily practice focused on domains of attention (focused and divided attention; attentional biases), memory (declarative, prospective, emotional memory), flexibility and inhibition, and problem-solving. Each session will discuss the relevance of these functions for the recovery from drug addiction and for managing affective/motivational symptoms commonly related to substance use (i.e., craving, anxiety, depression, trauma).
BEHAVIORALActive Control
The active control intervention will be composed of active, but non-essential aspects of the larger treatment program (i.e., those that treatment programs do not believe are necessary or central to their program, for example, art classes, exercise classes, chore time, or extra 12 steps meetings). This will ensure that subjects are not being prevented from accessing treatment that is already known to be helpful in substance use recovery, that the active control condition and NEAT intervention have equivalent credibility and expectancies, and optimizing the generalizability of findings.

Inclusion criteria
1. Enrolled in an established substance use treatment program, such as the Women in Recovery or 12&12 programs, Oxford Houses or others to be identified in the region) and diagnosed with Opioid Use Disorder and/or Amphetamine Use Disorder based on DSM V criteria using MINI structured interview. 2. Able to provide written informed consent. 3. Have sufficient proficiency in the English language to understand and complete interviews, questionnaires, and all other study procedures. 4. Completion of at least an 8th grade education, to help facilitate ability to engage in the written materials included in the NEAT program. 5. Current mental or physical health symptoms that require immediate attention (such as suicidal ideation with intent or plan; active psychotic symptoms; delirium; etc.)
Exclusion criteria
1. 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). 2. Non-correctable vision or hearing problems. For individuals to complete the brain imaging portion of the project, the following additional
