Brief Summary

In this observational cohort study, the researchers propose to first identify a psychophysiological marker of methamphetamine cue-reactivity and its incubation with abstinence from methamphetamine use (MUD) and examine group-differences between men who have sex with men (MSM) and non-MSM MUD. The primary objective is to identify psychophysiological markers of methamphetamine (MA) cue-reactivity and its abstinence incubation. The secondary objective is to examine group-differences in methamphetamine use disorder (MUD) individuals between homosexual men (MSM) and heterosexual men (non-MSM). The primary endpoint is to assess incubation of cue-reactivity longitudinally with its reduction in cognitive reappraisal, and the secondary endpoint is to examine the impact of cognitive reappraisal on clinical outcomes of methamphetamine use disorder (MUD) in homosexual men (MSM). 2-year long study. Screening and enrollment will be done at different locations of the Addiction Institute of Mount Sinai. The EEG session will be done at Icahn School of Medicine at Mount Sinai. Participation in the research study will be for a single EEG session.

Outcome Measures

Primary Outcomes (1)

  • Change in EEG-derived late positive potential (LPP) Amplitude

    Change in amplitude (or incubation of) the EEG-derived late positive potential (LPP) - an objective neurophysiological marker of drug cue-reactivity - occurs 400 msec after the onset of a drug-related cue. The LPP amplitude has also shown to predict self-reported craving, simulated drug-seeking behavior and relapse, highlighting the clinical utility of this objective metric of cue-reactivity.

    at approx. 2 weeks and 3 months abstinence

Study Arms (4)

MSM - MUD (Current)

Participants who are MSM and are currently using methamphetamine (MA abstinence: 2 weeks; range: 1-3 weeks).

Behavioral: Cognitive Reappraisal

MSM - MUD (Abstinent)

Participants who are MSM and are abstaining from using methamphetamine (MA abstinence: 3 months; range: 2-4 months).

Behavioral: Cognitive Reappraisal

non-MSM - MUD (Current)

Participants who are not MSM and are currently using methamphetamine (MA abstinence: 2 weeks; range: 1-3 weeks).

Behavioral: Cognitive Reappraisal

non-MSM - SUD (Abstinent)

Participants who are not MSM and are abstaining from using methamphetamine (MA abstinence: 3 months; range: 2-4 months).

Behavioral: Cognitive Reappraisal

Interventions

an emotion-regulation strategy while being asked to complete cognitive tasks.

Eligibility Criteria

Age18 Years - 60 Years
Sexmale(Gender-based eligibility)
Gender Eligibility DetailsThis is a study on MSM and non-MSM males only, who have shown to be at a high risk for methamphetamine use disorder.
Healthy VolunteersNo
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

44 current MA-using (MA abstinence: 2 weeks; range: 1-3 weeks), and 44 MA-abstinent (MA abstinence: 3 months; range: 2-4 months), individuals with MUD. Importantly, 50% in each group will be MSM, and the other 50% will be non-MSM men, resulting in 4 groups: (1) MSM/current MA, (2) MSM/abstinent, (3) non-MSM/current MA, and (4) non-MSM/abstinent; n=22 per group, matched on age and HIV status. Men who identify as "homosexual/gay" or "bisexual" and/or report having had sex with a man in the last 12 months will be defined as "MSM" and those who identify as "heterosexual/straight" and do not report having sex with men in the last 12 months as "non-MSM".

You may qualify if:

  • Ability to understand and give informed consent
  • Identify as either MSM or non-MSM
  • Males; Age 18-60
  • DSM-5 Diagnosis of MUD (Methamphetamine Use Disorder)
  • Have appropriate abstinence duration \[i.e., current Methamphetamine users (MA): 2 weeks (range: 1-3 weeks); MA-abstinent: 3 months (range: 2-4 months)\]
  • Treatment-seeking MUD must be in a treatment facility for substance use disorder, with MA as the primary drug (at the first visit)
  • Treatment-seeking MUD must be abstinent from MA use for approximately 2 weeks (range: 1-3 weeks) at enrollment.

You may not qualify if:

  • Women
