From an emotion regulation framework, generalized anxiety disorder (GAD) can be conceptualized as a syndrome involving heightened intensity of subjective emotional experience, poor understanding of emotion, negative reactivity to emotional experience, and the use of maladaptive emotion management strategies (including overreliance on cognitive control strategies such as worry). The current study sought to replicate previous findings of emotion dysregulation among individuals with GAD and delineate which aspects of emotion dysregulation are specific to GAD or common to GAD and another mental disorder (social anxiety disorder). Individuals with GAD reported greater emotion intensity and fear of the experience of depression than persons with social anxiety disorder and nonanxious control participants. Individuals with social anxiety disorder indicated being less expressive of positive emotions, paying less attention to their emotions, and having more difficulty describing their emotions than either persons with GAD or controls. Measures of emotion differentiated GAD, social anxiety disorder, and normal control groups with good accuracy in a discriminant function analysis. Findings are discussed in light of theoretical and treatment implications for both disorders.

Posttraumatic stress disorder (PTSD) and alcohol dependence (AD) frequently co-occur, although results of both cross-sectional and longitudinal studies evaluating the nature of their relationship have been mixed. There has been varied support for competing models explaining how these conditions influence one another. To assess both the self-medication and mutual maintenance models, as well as examine the potential moderating role of drinking motives, the current study used Generalized Estimating Equations to evaluate daily associations for an average of 7.3 days between PTSD symptoms and alcohol use in a mixed-gender sample of individuals who met criteria for both PTSD and AD. Results generally supported a self-medication model with elevated PTSD symptoms predictive of greater alcohol use on that same day and on the following day. Contrary to a mutual maintenance model prediction, drinking did not predict next-day PTSD symptoms. Results also indicated that both coping and enhancement drinking motives were significant moderators of the PTSD and drinking relationships, suggesting that these relationships may be more or less salient depending on an individual’s particular drinking motivations. For example, among those higher on coping drinking motives, a 1-unit increase in PTSD symptom severity was associated with a 37% increase in amount of alcohol consumed the same day, while among those low on coping drinking motives, a 1-unit PTSD increase was associated with only a 10% increase in alcohol consumption. We discuss implications of these findings for the larger literature on the associations between PTSD and alcohol use as well as for clinical interventions.
