Brief Summary

Craving is the strong desire for something, such as for substances in drug addiction and food or other activities in everyday life. Recent work suggests craving can influence how people make decisions and assign value to choice options available to them, yet the neural mechanisms underlying these interactions between craving and valuation remain unknown. To address this, this study uses cognitive decision-making tasks that measure how much individuals will pay (from a study endowment) to have everyday consumer items or snack foods when they crave something specific (opioids or a specific snack, respectively). First, the study will identify the neural mechanisms for how drug craving (craving for opioids) interacts with valuation for consumer items that have associations with drug use or not in people receiving treatment for opioid use disorder (OUD). This will be evaluated in the activity patterns and interactions among brain regions involved in craving and value assignment during decision-making. Then, the study will examine for parallel mechanisms for how food craving (craving for a specific snack) interacts with valuation for snack food items that have similar features to the craved snack or not in people receiving treatment for OUD and non-psychiatric community control participants.

Outcome Measures

Primary Outcomes (2)

  • Willingness-to-pay

    The amount that a participant would be willing to pay for different available choice options. This is measured during the decision-making tasks in which participants are shown images of consumer items or snack foods and report how much they would be willing to pay to have the different items in that moment.

    during the task

  • fMRI-BOLD activity measured during willingness-to-pay decisions

    Functional MRI data will be analyzed to measure changes in blood-oxygen-level-dependent (BOLD) signal in specific regions of interest based on prior research (ventral striatum, ventromedial prefrontal cortex, amygdala, and insula) as participants make willingness-to-pay decisions during each task.

Study Arms (2)

Consumer Items Willingness-to-Pay Task

EXPERIMENTAL

Men and women with OUD receiving medications for OUD treatment will complete a decision-making task during functional magnetic resonance imaging (fMRI) in which they indicate their willingness-to-pay for everyday consumer items that have associations with drug use or not. Interleaved with blocks of the task, participants will briefly observe stimuli that can produce a change in their psychological state and drug craving, via two psychological/behavioral interventions: Audio-visual stimuli (Neutral-Relaxing) and Audio-visual stimuli (Drug).

Behavioral: Audio-visual stimuli (Neutral-Relaxing)Behavioral: Audio-visual stimuli (Drug)

Snack Foods Willingness-to-Pay Task

EXPERIMENTAL

Men and women with OUD receiving medications for OUD treatment and control participants from the community will complete a decision-making task during functional magnetic resonance imaging (fMRI) in which they indicate their willingness-to-pay for snack food items that vary in their features (savory, sweet, etc.). Interleaved with blocks of the task, participants will briefly observe stimuli that can produce a change in their psychological state and food craving, via two psychological/behavioral interventions: Audio-visual stimuli (Non-Food) and Audio-visual stimuli (Food).

Behavioral: Audio-visual stimuli (Non-Food)Behavioral: Audio-visual stimuli (Food)

Interventions

Audio instruction for participant to allow themselves to experience their feelings followed by 3-min passive viewing of images of neutral everyday objects (e.g., tools, dirt) and their use (construction, gardening).

Consumer Items Willingness-to-Pay Task

Audio instruction for participant to allow themselves to experience their feelings followed by 3-min passive viewing of images of drug paraphernalia (e.g., syringe, tourniquet, heroin) and preparation.

Consumer Items Willingness-to-Pay Task

Audio instruction for participant to focus their attention on the experimenter followed by 3-min audio-guided viewing of the experimenter opening/unwrapping an everyday object (e.g., box of crayons) and taking out its contents.

Snack Foods Willingness-to-Pay Task

Audio instruction for participant to focus their attention on the experimenter followed by 3-min audio-guided viewing of the experimenter opening/unwrapping a snack (e.g., chocolate bar, bag of chips) and taking out its contents.
