Abstract
BACKGROUND This study examined the incremental validity of the Contrast Avoidance Model (CAM) in predicting generalized anxiety disorder (GAD) symptoms when compared against well-established constructs in the GAD literature: intolerance of uncertainty (IU) and negative problem orientation (NPO). METHOD In this study, 185 students (108 of whom endorsed clinical levels of GAD symptoms) completed questionnaires to assess for all constructs. GAD symptoms were regressed on measures of contrast avoidance (CA; Contrast Avoidance-General Emotion and Contrast Avoidance-Worry Questionnaires; Llera & Newman, 2017) tendencies in addition to measures of IU and NPO in separate analyses. Commonality analyses explored the unique versus overlapping contributions of each factor in explaining GAD symptoms. RESULTS In all models, CA was a significant predictor after controlling for demographic variables (age, gender, race, and ethnicity) and both IU and NPO. This was also true when excluding CA items referencing worry. All variables contributed unique explanatory power in the prediction of GAD. CONCLUSION Results provide evidence of the incremental validity of the CAM as a model of GAD.

Abstract
This study examined the relationship between the Contrast Avoidance Model (CAM; Newman & Llera, 2011) and impairment in the problem-solving process using an in-vivo laboratory-based problem-solving task. We also explored whether general emotional CA tendencies explained the relationship between trait worry and problem-solving outcomes. In this study, 185 participants (42 of whom met diagnostic criteria for generalized anxiety disorder) engaged in a problem-solving task, and reported outcomes related to ability to generate solutions, confidence in solutions, intention to implement solutions, and state anxiety levels. According to results, higher general emotional CA tendencies predicted significantly more difficulties on most problem-solving outcomes. Further, CA tendencies mediated between trait worry and some, but not all, problem solving outcomes. Overall, CA appears to be linked to problem-solving deficits, and may help to explain some of the association between trait worry and negative problem-solving outcomes.

Abstract
The Contrast Avoidance Model (CAM; Newman & Llera, 2011) has been well established in the literature on the etiology and maintenance of generalized anxiety disorder (GAD). Research has investigated other factors that may also characterize GAD, such as fear of emotional responding, negative problem orientation (NPO), and negative beliefs about control; however, these have yet to be explored within the context of the CAM regarding maintenance of GAD symptoms. The purpose of this study was to explore the predictive relationship between the above-mentioned factors and GAD symptoms, mediated by contrast avoidance. Participants (N = 99, 49.5% of whom scored in the upper range on GAD symptoms) completed a series of questionnaires across three time points, each one week apart. Results indicated that fear of emotional responding, NPO, and sensitivity to low perceived control predicted CA tendencies a week later. CA tendencies then mediated the relationship between each predictor and GAD symptoms in the following week. Findings suggested that known vulnerabilities for GAD predict coping with distressing internal responses via sustained negative emotionality (such as through chronic worry) as a way to avoid negative emotional contrasts. However, this coping mechanism itself may maintain GAD symptoms over time.

Abstract
INTRODUCTION Generalized anxiety disorder (GAD) is common and disabling. Different versions of cognitive behavioral therapy (CBT) have been tested, but no treatment works for everyone. Therefore, researchers have attempted approaches to enhance CBT. AREAS COVERED The current narrative review examines meta-analyses and individual trials of CBT-based treatments for GAD. We focus on CBT and its cognitive and behavioral components as well as efforts to enhance CBT and its dissemination and generalizability. Enhancement efforts included interpersonal and emotional processing therapy, mindfulness-based CBT, emotion regulation therapy, intolerance of uncertainty therapy, the unified protocol, metacognitive therapy, motivational interviewing, and contrast avoidance targeted treatment. Emerging strategies to enhance dissemination have focused on technologically based treatments. Attempts at generalizability have included examination of efficacy within diverse racial and ethnic groups. EXPERT OPINION We conclude that CBT is efficacious, and a number of enhancement efforts have shown some promise in improving upon CBT in single trials. However, more research is needed, particularly efforts to determine which enhancements work best for which individuals and what are the mechanisms of change. Furthermore, few technological interventions have been compared to active treatments. Finally, much more attention needs to be paid to ethnic and racial diversity in randomized controlled trials.

Abstract
INTRODUCTION Many individuals believe that worry helps solve real-life problems. Some researchers also purport that nonpathological worry can aid problem solving. However, this is in contrast to evidence that worry impairs cognitive functioning. OBJECTIVE This was the first study to empirically test the effects of a laboratory-based worry induction on problem-solving abilities. PROCEDURE Both high (n = 96) and low (n = 89) trait worriers described a current problem in their lives. They were then randomly assigned to contemplate their problem in a worrisome (n = 60) or objective (n = 63) manner or to engage in a diaphragmatic breathing task (n = 62). All participants subsequently generated solutions and then selected their most effective solution. Next, they rated their confidence in the solution's effectiveness, their likelihood to implement the solution, and their current anxiety/worry. Experimenters uninformed of condition also rated solution effectiveness. RESULTS The worry induction led to lower reported confidence in solutions for high trait worry participants, and lower experimenter-rated effectiveness of solutions for all participants, relative to objective thinking. Further, state worry predicted less reported intention to implement solutions, while controlling for trait worry. Finally, worrying about the problem led to more elevated worry and anxiety after solving the problem compared to the other two conditions. CONCLUSIONS Overall, the worry induction impaired problem solving on multiple levels, and this was true for both high and low trait worriers.

Abstract
Children that have been maltreated may experience manifold negative effects later in life. Two such sequelae are social anxiety and dissociation. Recent studies have noted their frequent co-occurrence, but no hypothesis has yet been offered explaining how they interact. College undergraduates (N = 198) completed the Child Trauma Questionnaire, Liebowitz Social Anxiety Scale, and Cambridge Depersonalization Scale. Social anxiety significantly predicted severity of dissociation, and self-reported childhood maltreatment (CM) significantly predicted both social anxiety and dissociation. Notably, emotional abuse was the only significant subtype of CM to predict social anxiety. Furthermore, CM moderated the relationship between social anxiety and dissociation, such that the presence of CM strengthened the predictive effect of social anxiety on dissociation. This study was the first to implicate CM as a mechanism in the social anxiety-dissociation relationship. This study was also the first to note a social anxiety-dissociation link in a non-clinical sample, thus demonstrating the existence of this relationship along a continuum of severity - not solely for those with extreme disturbances.

Abstract
The Contrast Avoidance (CA) model (Newman & Llera, 2011) proposed that individuals with generalized anxiety disorder (GAD) fear sharp emotional shifts (or contrasts), such as the shift from a pleasant or neutral state to one of sudden distress following a negative event. Further, the model suggests that chronic worry is employed by those with GAD to sustain negative emotionality as a means to avoid sudden shifts into negativity. The model has received empirical support; however, no validated measure exists to assess CA tendencies. In this paper we developed and tested two measures of CA: one focusing on worry, and another examining broader mechanisms of CA that could be used test whether CA is applicable to other disorders. In Study 1, Part 1, we used 3 samples of participants (each N=410) to perform item reduction, exploratory factor analysis, and confirmatory factor analysis. In Study 1, Part 2, we performed tests of construct validity. In Study 2, we used a new sample (N=126) to determine test-retest reliability. All data point to the strong psychometric properties of the CA questionnaires and their relationship to GAD. Both measures distinguished between participants reporting clinical levels of GAD symptoms and nonanxious controls, demonstrating their utility as complementary measures of CA tendencies.

Abstract
The Contrast Avoidance model (Newman & Llera, 2011) proposes that individuals with generalized anxiety disorder (GAD) are hypersensitive to sharp upward shifts in negative emotion that typically accompany negative events, and use worry to maintain sustained intrapersonal negativity in an attempt to avoid these shifts. Although research shows that worry increases negative emotionality and mutes further emotional reactivity to a stressor when compared to the worry period (e.g., Llera & Newman, 2010), no study has tracked changes in negative emotionality from baseline to worry inductions followed by a range of emotional exposures. Further, no study has yet assessed participants' subjective appraisals of prior worry on helping to cope with such exposures. The present study tested the main tenets of the Contrast Avoidance model by randomly assigning participants with GAD (n=48) and nonanxious controls (n=47) to experience worry, relaxation, and neutral inductions prior to sequential exposure to fearful, sad, and humorous film clips. Both physiological (nonspecific skin conductance responses [NS-SCRs]) and self-reported emotional changes were observed. Results indicated that worry boosted negative emotionality from baseline, which was sustained across negative exposures, whereas low negative emotionality during relaxation and neutral inductions allowed for sharp increases in response to exposures. Furthermore, GAD participants found worry to be more helpful than other conditions in coping with exposures, whereas control participants reported the opposite pattern. Results provide preliminary support for the Contrast Avoidance model. This suggests that treatment should focus on underlying avoidance patterns before attempting to reduce worry behavior.

Abstract
Generalized anxiety disorder (GAD) is associated with substantial personal and societal cost yet is the least successfully treated of the anxiety disorders. In this review, research on clinical features, boundary issues, and naturalistic course, as well as risk factors and maintaining mechanisms (cognitive, biological, neural, interpersonal, and developmental), are presented. A synthesis of these data points to a central role of emotional hyperreactivity, sensitivity to contrasting emotions, and dysfunctional attempts to cope with strong emotional shifts via worry. Consistent with the Contrast Avoidance model, evidence shows that worry evokes and sustains negative affect, thereby precluding sharp increases in negative emotion. We also review current treatment paradigms and suggest how the Contrast Avoidance model may help to target key fears and avoidance tendencies that serve to maintain pathology in GAD.

Abstract
An important emphasis of the literature on generalized anxiety disorder (GAD) has been to achieve a greater understanding of the function of emotion (e.g., avoidance, dysregulation) in the etiology and maintenance of this disorder. The purpose of the following paper is to propose a new way of conceptualizing emotional sequelae in GAD by detailing the Contrast Avoidance Model of Worry. In presenting this model, we review theory and data that led to our current position, which is that individuals with GAD are more sensitive to feeling emotionally vulnerable to unexpected negative events, and that worry (the key pathological feature of GAD) is employed to prolong and maintain a negative emotional state thereby avoiding an unexpected negative emotional shift, or contrast experience. We also discuss implications for treatment given the presence of a new target for emotional exposure techniques. Finally, we establish the Contrast Avoidance Model within the framework of extant theories and models of pathogenic processes of GAD.

Abstract
The present study examined the effect of worry versus relaxation and neutral thought activity on both physiological and subjective responding to positive and negative emotional stimuli. Thirty-eight participants with generalized anxiety disorder (GAD) and 35 nonanxious control participants were randomly assigned to engage in worry, relaxation, or neutral inductions prior to sequential exposure to each of four emotion-inducing film clips. The clips were designed to elicit fear, sadness, happiness, and calm emotions. Self reported negative and positive affect was assessed following each induction and exposure, and vagal activity was measured throughout. Results indicate that worry (vs. relaxation) led to reduced vagal tone for the GAD group, as well as higher negative affect levels for both groups. Additionally, prior worry resulted in less physiological and subjective responding to the fearful film clip, and reduced negative affect in response to the sad clip. This suggests that worry may facilitate avoidance of processing negative emotions by way of preventing a negative emotional contrast. Implications for the role of worry in emotion avoidance are discussed.
