Determining the Role of Social Reward Learning in Social Anhedonia (SAMI)

July 24, 2026 updated by: Junghee Lee, University of Alabama at Birmingham

Determining the Role of Social Reward Learning in Social Anhedonia in First-Episode Psychosis Using Motivational Interviewing in a Perturbation-Based Neuroimaging Approach

This is a clinical trial study that aims to evaluate the specificity of the relationship between reduced sensitivity to social reward and social anhedonia at both behavioral and neural levels. Individuals who recently experienced their first-episode psychosis will be recruited. Participants will be randomized 1:1 to motivational interviewing or a time- and format-matched control probe. At pre- and post-probe, participants will perform two social reward learning tasks in the scanner. With this design feature, we will examine the relationship between sensitivity to social reward and reduced subjective experience of social pleasure at both the behavioral and neural levels.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 35 years (Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age 18-35 years
  • A first episode of a psychotic illness that began within the past three years
  • Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 diagnosis of schizophrenia, schizophreniform, or schizoaffective disorder
  • Taking 2nd generation antipsychotic medications
  • Estimated premorbid IQ not less than 70 as assessed with the Wechsler Test of Adult Reading
  • Appropriate for scanning (i.e., no pacemaker or metal implants) and expressed willingness to participate in scanning
  • Sufficient fluency in English to comprehend testing procedures
  • Corrected vision of at least 20/30

Exclusion Criteria:

  • No evidence that substance use makes the diagnosis ambiguous (rule out substance-induced psychosis)
  • No evidence of moderate or severe alcohol or substance use disorder in the past 3 months
  • No clinically significant disease based on medical history (e.g., epilepsy) or significant head injury
  • For females: no current pregnancy
  • No sedatives or anxiolytics on the day of assessment
  • No medication change 3 weeks prior to enrollment

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Motivational Interview Intervention
This arm involves three 45-minute sessions on motivational interviewing targeting sensitivity to social reward.
Behavioral: Motivational Interviewing
Three motivational interviewing sessions will target sensitivity to social reward, including subjective evaluation of social interaction, socially rewarding stimuli, and events (e.g., interactions with others, feedback from others).
Active Comparator: Active Control Intervention
This arm involves three 45-minute sessions on didactic training on nutrition.
Behavioral: Nutrition Didactic Training
The Nutrition didactic training will ask participants to discuss pros and cons of healthy eating habits and how to improve their current eating habits.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Response Bias
Time Frame: 3 weeks
Response bias is defined as the likelihood of making one response, such as the frequently rewarded stimulus, more than the other response during the perceptual social reward learning task
3 weeks
the number of optimal response
Time Frame: 3 weeks
The number of optimal response is defined as the number of responses choosing a stimuli with optimal outcomes (e.g., choosing a good over a neutral machine or choosing a neutral over a bad machine) during the inductive social reward learning task.
3 weeks
fMRI activation levels
Time Frame: 3 weeks
fMRI activation is defined as beta weights from general linear model from key regions of interests including the ventromedial prefrontal cortex, dorsal anterior cingulate cortex and ventral striatum during the perceptual social reward learning task and the inductive social reward learning task.
