简要总结
This will be a laboratory-based investigation of the behavioral and neural effects of intranasal oxytocin on craving for alcohol and approach bias in moderate to heavy alcohol using subjects. This study uses a within-subject, randomized, placebo-controlled, counterbalanced, crossover design to compare the effects oxytocin and placebo. In this way, all subjects will be scanned twice; once following oxytocin administration and once following placebo administration, and will complete a series of behavioral tasks (both in and out of the scanner) at both visits.

结局指标
主要结局
Alcohol cue craving score
时间窗: ~ 90 minutes post study drug administration
Subjects will be asked to perform a standardized alcohol cue exposure paradigm and be asked to rate their subjective craving following alcohol cue presentation using a standard visual analog scale. Craving scores (ranging from 1-10 on VAS) will be compared across both the active study drug and placebo.
Image approach task
时间窗: ~ 90 minutes post study drug administration
Subjects will be asked to perform an image approach task where subjects are presented with a series of images and asked to pull or push a joystick following each presentation. Response direction and speed are recorded and compared across both the active study drug and placebo.
