Abstract Background The Contrast Avoidance Model postulates that individuals with generalized anxiety disorder (GAD) fear a sharp spike in negative emotion, and thus, prefer to worry to maintain their negative affect rather than being in a more euthymic state, such as relaxation. Relaxation induced anxiety (RIA) is a paradoxical phenomenon wherein people experience a spike in their anxiety during relaxation training. Because these phenomena may also operate among individuals with major depressiv...

Worry, rumination, and obsessive thinking are theorized to differ on temporal orientation, positive perceived function, degree of intrusiveness, and discordance with one’s self-concept. However, prior findings with respect to such differences may be due to method variance of the measures used and/or inclusion of items confounded by diagnostic symptoms. Accurately capturing differences between types of perseverative thought linked to psychopathology and understanding whether such aspects are comm...

Abstract This study was a secondary analysis of LaFreniere and Newman (2016), a randomized controlled trial comparing two ecological momentary interventions (EMIs) for generalized anxiety disorder (GAD): The worry outcome journal (WOJ) and thought log (TL). We predicted that higher thought-related distress would be a mediator by which higher uncontrollability beliefs (UB) would hinder the efficacy of the WOJ, but not the TL. Fifty-one undergraduates who met GAD criteria underwent one of the EMIs...

Abstract Theories of cognitive therapy have long proposed that those with generalized anxiety disorder (GAD) have inaccurate expectations. By challenging them with objective evidence, symptoms are thought to decrease. To test these premises, this study used ecological momentary assessment (EMA) during the Worry Outcome Journal (WOJ) treatment to determine the percentage of GAD worries that did not come true. We then analyzed the association between participants' untrue worry percentages and GAD ...

The contrast avoidance model (CAM) suggests that worry increases and sustains negative emotion to prevent a negative emotional contrast (sharp upward shift in negative emotion) and increase the probability of a positive contrast (shift toward positive emotion). In Study 1, we experimentally validated momentary assessment items (N = 25). In Study 2, participants with generalized anxiety disorder (N = 31) and controls (N = 37) were prompted once per hour regarding their worry, thought valence, and...

Abstract Despite attention on overlap and distinction between generalized anxiety disorder (GAD), social anxiety disorder (SAD), and major depressive disorder (MDD), interpersonal specificity (distinct, prototypical interpersonal features) between the disorders has been understudied. There is emerging evidence for such specificity (e.g., Erickson et al., 2016), but most studies relied on self-report, and not all studies controlled for shared variance between the disorders, complicating interpret...

This experiment examined learning tendencies in generalized anxiety disorder (GAD) using reinforcement feedback for probabilistic outcomes. One hundred sixty-six GAD and 105 non-GAD participants were randomized to a computerized probabilistic learning task that used either negative or positive reinforcement. Participants chose between stimuli with specific probabilities of reinforcement to learn which of each pair had the highest probability. Reinforced choices either removed an angry face (nega...
