Outcome Measures
Primary Outcomes (1)
Biphasic Alcohol Effects Scale:Total Mood
Change from baseline to peak cortisol response, during the 2nd alcohol challenge session, subjective response as measured by Biphasic Alcohol Effects Scale: Total Mood. Biphasic Alcohol Effects Scale: Total Mood: minimum = 0, maximum = 106, higher scores indicate better outcomes.
