Treating individuals with social anxiety disorder and at-risk drinking: Phasing in a brief alcohol intervention following paroxetine

Paroxetine alone is not sufficient to decrease alcohol use in socially anxious alcoholics seeking anxiety treatment. We tested the hypothesis that adding a brief-alcohol-intervention (BI) to paroxetine would decrease alcohol use. All subjects (N = 83) had a diagnosis of social anxiety disorder, endorsed drinking to cope with anxiety, were NIAAA-defined at-risk drinkers, and were randomized to either paroxetine alone, or paroxetine plus BI. Both groups showed significant improvement in both social anxiety severity (F(5,83) = 61.5, p < 0.0001) and drinking to cope (e.g. F(4,79) = 23, p < 0.0001) and these two constructs correlated with each other (B = 3.39, SE = 0.696, t(71) = 4.88, p < 0.001). BI was not effective at decreasing alcohol use (e.g. no main effect of group, all p values >0.3). Paroxetine decreased social anxiety severity in the face of heavy drinking and decreasing the anxiety was related to a concurrent decrease in coping related drinking. BI was not effective at decreasing drinking or drinking to cope.

► People with social anxiety often use alcohol to cope and become at-risk drinkers. ► Paroxetine decreases social anxiety but not drinking quantity and frequency. ► This randomized trial evaluates adding a brief alcohol intervention to paroxetine. ► Participants reported decreased anxiety and decreased use of alcohol for coping. ► The brief alcohol intervention did not change drinking quantity and frequency.
