Newswise, March 20, 2017 — Stress
and anxiety are widely believed to contribute to drinking. Alcohol is thought
to reduce tension caused by stress (the “flight or fight” response) as well as
alleviate the unpleasant symptoms of anxiety (anticipation of the
unpredictable, impending threats).
Prior research, however, has yielded
inconsistent findings as to the unique relations between stress and anxiety, on
the one hand, and alcohol consumption and alcohol use disorders, on the other
hand.
This study was designed to examine
how differences in self-reported levels of anxiety, anxiety sensitivity, and
perceived stress impact the frequency and intensity of drinking, alcohol
craving during early withdrawal, and alcohol craving and stress reactivity.
Recent drinking was assessed in 87
individuals (70 men, 17 women) with alcohol use disorders (AUDs). Three
distinct measures were used to evaluate anxiety, anxiety sensitivity, and
perceived stress.
A subset of 30 subjects was admitted
to a medical center to ensure alcohol abstinence for one week: measures of
alcohol craving were collected twice daily. On day 4, subjects participated in
a public speaking/math challenge, before and after which measures of cortisol
and alcohol craving were collected.
In these heavy drinkers, measures of
anxiety as compared with perceived stress were more strongly associated with a
variety of alcohol-related measures.
While alcohol studies often use the
terms anxiety, anxiety sensitivity, and stress interchangeably, this study
showed the importance of differentiating among the three terms given their
unique relationships with drinking, craving, and stress reactivity among
individuals with AUDs.
