title: Alcohol and sober mood state in female social drinkers.
abstract: The goals of the present study were to measure the relationship between alcohol consumption in 93 female social drinkers and their cognitive functioning and mood in the sober state, and to investigate the possible causal effects of alcohol consumption on these variables. In the first test session, a limited relationship was seen between previous alcohol consumption and sober cognitive performance. A strong relationship was found between alcohol consumption and self-reported depression and anger in the sober state. Either a prolonged reduction in alcohol consumption or a prolonged maintenance of alcohol consumption was undertaken by random subsets of the original sample. In the second test session 6 weeks later, women who had been randomly selected to reduce their alcohol intake showed decreases in depression, anger, and mental confusion when they were sober, relative to women who maintained or increased their alcohol consumption over the same period of time. We found no changes in cognitive performance in these groups. We concluded that the simplest explanation of the findings is that relatively low levels of alcohol consumption produce substantial increases in depression and anger in the sober state in female social drinkers. The value of considering alcohol consumption as a continuous variable rather than a dichotomous variable with "safe" and "unsafe" zones was discussed.
