If the model proves that it can modify disorder symptoms through manipulating the main components involved in the model, it has provided evidence to approve itself. Newman and Llera (2011) attempted to explain these inconsistencies and find an answer to the questions concerning positive beliefs about worry and actively using worry despite its emotional consequences and proposed the CAM. Unlike the previous knowledge about it, IU is not a thing that one obtains during life, but it is learning the safety conditions that a person should obtain instead. This suggests that treatment should focus on underlying avoidance patterns before attempting to reduce worry behavior. Michelle G. Newman, Sandra J. Llera, Thane M. Erickson, Amy Przeworski, Research output: Contribution to journal Article peer-review. 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. However, to provide support for the transdiagnostic applicability of the CAM, we reviewed studies that investigate the activating effects of another form of repetitive negative thinking. From the viewpoint of these individuals, the emotions are difficult to understand and hardly could be relieved. However, few studies in the literature have directly investigated the association between these emotional factors and the CAM. Worry is defined as a chain of repetitive and uncontrollable thoughts about possible future negative events (Roemer & Borkovec, 1993). A meta-analysis showed that perceived control has a strong relationship with trait anxiety, and it is mostly associated with GAD, among other anxiety disorders. The main critique has been proposed by the Generalized Unsafety Theory of Stress (GUTS). Need abbreviation of Contrast Avoidance Model? 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). A novel theory of experiential avoidance in generalized anxiety disorder: a review and synthesis of research supporting a contrast avoidance model of worry. Addressing such processes would help these models to explain spontaneous initiation of worry and the continuity or chronicity of worry and anxiety responses (Brosschot et al., 2016). Contrast Avoidance model claims that the main fear of individuals with generalized anxiety disorder is a negative emotional contrasts (shifts) and they use worry to create and maintain the negative and stable emotional state, so in this way, they could avoid from a negative emotional contrast. In another study, which asked participants with GAD to reduce their negative emotional state by adaptive methods, similar results were obtained. Show all article previews Show all article previews. Art. However, more studies are required to investigate the contribution of intolerance of uncertainty in CA. Does generalized anxiety disorder predict coronary heart disease risk factors independently of major depressive disorder? Did you know that with a free Taylor & Francis Online account you can gain access to the following benefits? Llera and Newman (2017) developed measures for assessing CA tendencies from two distinct perspectives, one uniquely focusing on worry (Contrast avoidance questionnaire-Worry; CAQ-W) and the other assesses these tendencies more broadly that could measure CA as a transdiagnostic construct (Contrast avoidance questionnaire-General Emotion; CAQ-GE). According to the CAM, worry actively induces negative emotion as a way to avoid an emotional contrast. In this treatment method, first by teaching relaxation, acceptance, and mindful awareness of interoceptive states, individuals engage in relaxation, and the parasympathetic system becomes dominant. Worry develops in individuals who experience high levels of emotional reactivity and have maladaptive efforts in dealing with these emotions (Newman et al., 2014; Rothbart & Sheese, 2007). Also, trait worry is associated with higher heart rate and skin conductance and lower HRV during sleep (Brosschot et al., 2007; Weise et al., 2013). Further, the model suggests that chronic worry is employed by those with . The Contrast Avoidance model (Newman & Llera, 2011) proposes that individuals with generalized anxiety disorder (GAD) are excessively sensitive to negative emotional shifts (contrasts) in response to unpleasant events, and thus recruit a state of sustained intrapersonal negativity via worry as a defensive stance against such shifting states. 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. Moreover, studies that have conducted so far demonstrated the RIA in individuals with panic disorder (Cohen et al., 1985; Ley, 1988; Wells, 1990). It suggests that the effect of emotional experience is conditional on the degree of contrast that has with the preceding emotional state. IU consists of prospective and inhibitory components. Although principles of the CAM have been supported in empirical studies, addressing the model from a critical point of view may help to enrich the model. A study aimed to compare emotional sensitivity in individuals with GAD, social anxiety disorder, and healthy controls showed that GAD participants have higher emotional sensitivity compared to other diagnostic groups (Bui et al., 2017). Towson University Graduate Theses and Dissertations, Maryland Shared Open Access Repository Home, http://library.towson.edu/digital/collection/etd/id/68509. Thus, emotional reactivity could be an essential vulnerability factor in the development of maladaptive emotion regulation mechanisms such as creating and sustaining negative emotions through worry. Nevertheless, there were some critiques on the CAM in the literature. Heightened emotional intensity strongly associated with GAD (Mennin et al., 2009). We also discussed the emotional factors that could be related to the development of CA tendencies in a range of emotional disorders. It seems that negative contrast sensitivity and RIA are transdiagnostic constructs and contribute to other disorders (Kim & Newman, 2019). It seems that the CAM will follow the same path. The finding which is consistent with recent studies suggests that although worry may reduce the possibility of experiencing a negative emotional contrast, it will increase the likelihood of experiencing a positive emotional contrast (Newman et al., 2016; Llera & Newman, 2014; Kim & Newman, 2016). Problems in controlling and regulating emotions in GAD are also more than other disorders (Mennin et al., 2009). Also, these findings indicate the role of negative contrast sensitivity in MDD. Effortful control moderates relationships between worry and symptoms of depression and anxious arousal. and transmitted securely. RIA is defined as a sudden increase in anxiety, body tension, or anxious thoughts and mental images while trying to be relaxed (Heide & Borkovec, 1983). Vanderlind WM, Everaert J, Caballero C, Cohodes EM, Gee DG. The Contrast Avoidance Model purports that as a result of these factors, these individuals would rather feel badly all the time than be taken by surprise, which is consistent with, but provides further elaboration on the IU Model. An unpleasant emotional state following a pleasant emotional state is perceived as more unpleasant, and following an unpleasant emotional state is perceived as less unpleasant. Data from a neuroimaging study supports the notion that individuals with GAD have difficulty in experiencing negative emotional shifts. That is, in order to avoid a sudden negative emotional shift, the person puts himself/herself in a negative emotional state through worry. In a study, firstly, 125 participants were categorized into three groups of verbal worry, imagery-based worry and distraction. A study which used daily worry reports and morning cortisol level to examine the relationship between adolescents worry and the Hypothalamic-Pituitary-Adrenal (HPA) axis activity and health symptoms, found that cortisol level increased after days full of worry. This claim is based on numerous studies suggesting that worry, compared to baseline or a nonworry period, creates and sustains negative emotions, and physiological arousal (Llera & Newman, 2010). Another hypothesis of the CAM is that worry compared to distraction, and neutral state or relaxation leads to a lower increase in subsequent negative emotions; however, in this study, the hypothesis only was supported at self-report measures. We also included a treatment method based on the CAM in our study. 2017 Jul;48(4):544-556. doi: 10.1016/j.beth.2016.10.001. Clin Psychol Sci. Moreover, individuals with GAD had less accuracy at estimating probabilities of desirable outcomes for both types of reinforcement. Limitations of the present study should be considered. The percentage of untrue worries in two different studies was calculated as 8591% (Borkovec et al., 1999) and 91.4% (LaFreniere & Newman, 2019a). A neuroimaging study showed that during worry and rumination, there was prominent activity in the anterior cingulate cortex (ACC), left insula, bilateral dorsolateral prefrontal cortex (DLPFC), right hippocampus and bilateral inferior temporal gyrus (ITG) in contrast to the neutral state. For example, longitudinal studies on different age groups will show us the developmental pathway of CA tendencies. They proposed that MDD may have an additional mediator and anhedonia, one of the hallmark symptoms of MDD, which characterizes with inability in feeling pleasure and decreased interest in positive activities, could be this additional mediator. Therefore, emotional sensitivity, heightened emotional intensity, and maladaptive emotion regulation strategies might lead the individuals with GAD to experience negative emotional contrasts as extreme, aversive, and out of control. ), The diagnosis and treatment of generalized anxiety disorder, https://doi.org/10.3238/arztebl.2013.0300, The interactive effect of worry and intolerance of uncertainty on posttraumatic stress symptoms, https://doi.org/10.1007/s10608-012-9512-1. The Contrast avoidance model (CAM) suggests that individuals with generalized anxiety disorder (GAD) avoid negative emotional contrasts (shifts) by creating and sustaining negative emotions. Individuals high in trait prospective IU (which is uniquely associated with GAD) were unable to disengage in worry, even when certainty provided, and they experienced sustained negative emotions (Ranney et al., 2018). AR has shown efficacy in the treatment of anxiety (Barlow et al., 1992; Bolognesi et al., 2014; Borkovec & Costello, 1993; Ost & Breitholtz, 2000; Siev & Chambless, 2007). The items of the first component of CAQ-W (Worry to Avoid Negative Emotional Shifts) implicate the role of perceived lack of control (Llera & Newman, 2017); however, studies are required to investigate the contribution of this transdiagnostic construct in the CAM. Epub 2016 Oct 29. Psychol. Several path models were run, indicating that: 1) CAQ predicted scores on the GAD-Q-IV, IUS, and PSWQ; 2) IUS partially mediates the relationship between CAQ and GAD-Q-IV; and 3) IUS mediated the relationship between CAQ and FoC. However, these models have failed to explain the healthy and pathological level of worry (Hallion et al., 2019). Results showed that sad facial expression in response to rumination supported a Contrast Avoidance Model. ( 1914) is rooted in cognitive psychology. The Contrast Avoidance Model (CAM) postulates that individuals at risk for pathological worry and GAD symptoms uniquely fear emotional shifts from neutral or positive emotions into negative emotional states, and consequently use worry to maintain negative emotion in order to avoid shifts or blunt the effect of negative contrasts. Epub 2021 Mar 29. Preliminary data suggest that emotion regulation mechanisms proposed by the CAM could apply to rumination and MDD. Dive into the research topics of 'Basic science and clinical application of the contrast avoidance model in generalized anxiety disorder'. Thus, future studies could develop the CAM by transdiagnostic examination of contrast sensitivity in emotional disorders.

Vsl A, Zinbarg R, Hilpert P, Allemand M, Flckiger C. Front Psychol. Furthermore, GAD participants found worry to be more helpful than other conditions in coping with exposures, whereas control participants reported the opposite pattern. author = "Newman, {Michelle G.} and Llera, {Sandra J.} Emotionally reactive individuals with lower levels of attentional and emotional control are prone to the development of worry, and their preferred emotion regulation strategy may be creating and sustaining negative affect since thereby, they feel more control over the emotions and events. Rumination may function similarly in depression, although this proposal requires further research. The Contrast Avoidance Model (CAM) postulates that individuals at risk for pathological worry and GAD symptoms uniquely fear emotional shifts from neutral or positive emotions into negative emotional states, and consequently use worry to maintain negative emotion in order to avoid shifts or blunt the effect of negative contrasts. That is, the preceding emotional state determines the effect of an emotional experience. Cogent Psychology Abstract The Contrast avoidance model (CAM) suggests that individuals with generalized anxiety disorder (GAD) avoid negative emotional contrasts (shifts) by creating and sustaining negative emotions through worry, and the main fear in these individuals is negative emotional contrasts. Learning models of chronic anxiety that specifically explain worry, generally assert that worry is maintained by certain positive outcomes for the individual such as inhibition of intense physiological responses (Borkovec, 1994) or preventing sudden and negative emotional contrasts (Llera & Newman, 2014). The CAM claims that the main fear of individuals with GAD is a negative emotional contrast, which has a unique position among other theoretical models (Dugas et al., 2004; Mennin, 2004; Wells, 2006). Participants with high MDD, high GAD and low MDD & GAD controls were randomly assigned to engage in either rumination, worry or relaxation. Also, lower HRV has been shown in obsessive-compulsive disorder, social anxiety disorder, and panic disorder (Pittig et al., 2013). This output contributes to the following UN Sustainable Development Goals (SDGs). The results show that these emotional vulnerability factors may play a role in the development of CA tendencies. Anhedonia might exacerbate the RIA by preventing feeling pleasure from relaxation. 2021 Sep;60(3):400-413. doi: 10.1111/bjc.12289. Like what we see in RIA, the CAM proposes that being in a relaxed state increases the possibility of experiencing a sudden increase in negative emotions in facing a stressful event. However, to develop a well-established treatment protocol, randomized clinical trials are needed to be conducted to evaluate its efficacy. So, they would not experience negative emotional contrasts. Emotion and Emotion Preferences in Daily Life: The Role of Anxiety. Also, in self-report measures, the worry was related to heightened negative affect (Newman et al., 2016). Download PDFs Export citations. The affective contrast theory proposed by Bacon et al. Contact Info: According to deficit-based cognitive models (Hirsch & Mathews, 2012), pathological worry is mainly maintained by deficits in cognitive control, especially in the context of negative emotional information. The present article suggests that these beliefs emerge from both. In the cognitive modal, modification of patients fear of negative emotional contrasts and positive beliefs about worry take place (Fonzo & Etkin, 2016; Newman & Llera, 2011). Heightened negative affect caused by rumination leads to reduced ability to engage in effective problem-solving and maladaptive behaviors (McLaughlin et al., 2007; Nolen-Hoeksema et al., 2008). Moreover, by the repeated implementation of exposure to negative emotional contrast (that is, long AR exercises preceding negative imaginal exposure), patients may desensitize to their aversion of sudden negative emotional contrasts. The treatment method discussed above is primarily proposed for GAD. In addition, these results implicate that CA tendencies exist in disorders other than GAD, which requires further study to support the contribution of these tendencies in emotional disorders. Then exposure to negative emotional contrast takes place via exposure to a feared outcome, which according to the CAM, this process is the main fear of individuals with GAD (Newman & Llera, 2011).
