  Purpose

The purpose of the study is to examine the effects of intranasal oxytocin administration on social cognition in patients receiving methadone maintenance treatment (MMT), examine the effects of intranasal oxytocin administration on opioid craving and on the subjective effects of methadone, and examine the effects of intranasal oxytocin administration on implicit preferences for drug-related and social stimuli in patients receiving MMT.

Hypothesis 1: Patients will perform better on measures of social cognition (including affect recognition and recognition of sarcasm) after administration of oxytocin compared with placebo.

Hypothesis 2: Patients will demonstrate lower craving for opioids and greater subjective effects of methadone after administration of oxytocin compared with placebo.

Hypothesis 3: Patients will demonstrate increased implicit preferences for social stimuli and decreased implicit preferences for drug related stimuli after administration of oxytocin compared with placebo.

Primary Outcome Measures:
  • Computerized Social Cognition Tasks [ Time Frame: Participants will complete 2 days of the study. These 2 days will be at least a week apart. ]
    Participants will undergo computer tasks that measure social cognition, which include the TASIT, RMET, and the IAT. The TASIT measures the awareness of social inference, the RMET measures the ability to guess the emotions of others, and the IAT measures implicit associations.


Secondary Outcome Measures:
  • Craving Questionnaires [ Time Frame: Participants will complete 2 days of the study. These 2 days will be at least a week apart. ]
    Participants are asked to rate their current symptoms and current craving levels and for different substances.
