Contrast avoidance model of worry and generalized anxiety disorder: A theoretical perspective

The different areas of chronic stress and food addiction: Results from the LIFE-Adult-Study

There is an empirical association between stress and symptoms of food addiction (FA), but it is still not clear which domains of stress are the most relevant when it comes to FA, limiting the ability of researchers and practitioners to address problematic eating-related health outcomes. In order to address this gap in the literature, we analysed how different domains of chronic stress are related to FA. We used data from a subsample of the LIFE-Adult-Study (N = 1172), a German cohort study. We conducted a linear regression analysis with stress domains (Trier Inventory for Chronic Stress, TICS) as predictors of FA (Yale Food Addiction Scale, YFAS). In the second regression analysis we included sociodemographic variables, personality, and smoking as control variables. There was a significant and positive association between Social Overload, Work Discontent, Excessive Demands from Work, and Chronic Worrying and FA. After adding control variables, only Social Overload, Excessive Demands from Work, and Chronic Worrying remained significant predictors. Connections between stress domains and FA can serve as starting points for the development of meaningful interventions that support individuals self-care strategies (Social Overload), complexity management (Excessive Demands from Work), and coping with negative emotions (Chronic Worrying).

Large environmental changes reduce valence-dependent belief updating

When updating beliefs, humans tend to integrate more desirable information than undesirable information. In stable environments (low uncertainty and high predictability), this asymmetry favors motivation towards action and perceived self-efficacy. However, in changing environments (high uncertainty and low predictability), this process can lead to risk underestimation and increase unwanted costs. Here, we examine how people (n = 388) integrate threatening information during an abrupt environmental change (mandatory quarantine during the COVID-19 pandemic). Given that anxiety levels are associated with the magnitude of the updating belief asymmetry; we explore its relationship during this particular context. We report a significant reduction in asymmetrical belief updating during a large environmental change as individuals integrated desirable and undesirable information to the same extent. Moreover, this result was supported by computational modeling of the belief update task. However, we found that the reduction in asymmetrical belief updating was not homogeneous among people with different levels of Trait-anxiety. Individuals with higher levels of Trait-anxiety maintained a valence-dependent updating, as it occurs in stable environments. On the other hand, updating behavior was not associated with acute anxiety (State-Anxiety), health concerns (Health-Anxiety), or having positive expectations (Trait-Optimism). These results suggest that highly uncertain environments can generate adaptive changes in information integration. At the same time, it reveals the vulnerabilities of individuals with higher levels of anxiety to adapt the way they learn.

Psychometric Properties of the Iranian Version of Contrast Avoidance Questionnaires: Could Contrast Avoidance Be a New Transdiagnostic Construct?

The contrast avoidance model (CAM) hypothesizes that individuals with chronic worry recruit worry to create and maintain a negative emotional state to avoid sudden increases in negative emotions. Preliminary evidence using the contrast avoidance questionnaires (CAQs) suggests that there might be a similar mechanism across mood and other anxiety disorders. To continue to assess the CAQs, they should be adapted for other languages and evaluated across multiple symptom domains. The present study aimed to develop the Persian versions of the CAQs and examine the transdiagnostic nature of CAM across two studies. A large Persian-speaking college student sample (Total n = 1438) was used to evaluate the factor structure of the CAQs (Study 1) and the psychometric properties of CAQs (Study 2). Results supported the two-factor structure of the CAQ-W (worry) and CAQ-GE (general emotion). Results showed that CAQ-W was a significant predictor of anxiety-related measures. However, CAQ-GE and IUS-12 significantly predicted depressive and other symptoms over the CAQ-W. Results demonstrated excellent psychometric properties. They indicate that contrast avoidance, measured via CAQ-GE, could be a transdiagnostic construct, and CAQ-W may be more sensitive to anxiety-specific contrast avoidance among Persian speaking and/or Iranian individuals.

Examining the Factor Structure and Incremental Utility of the Contrast Avoidance Questionnaires via Bifactor Analysis

The negative emotional contrast avoidance model posits that pathological worry is maintained by the avoidance of negative emotional shifts. The Contrast Avoidance Questionnaires (CAQ-Worry and CAQ-General Emotion) aim to assess contrast avoidance beliefs and behaviors. Questions remain around the factor structures of the CAQs, whether such structures replicate in nonundergraduate samples, and whether their domain-specific factors are valid for independent use. This study used bifactor analysis in a large community sample (N = 827) to address these gaps in the literature. Results supported bifactor models of both measures. Complementary analyses supported the multidimensionality of the CAQ-Worry, including its strong general factor and independent use of two domain-specific factors, rather than the original three domain-specific factors. The CAQ-General Emotion's general factor was strong, but the merits of the Discomfort domain-specific factor require more exploration, and use of the Avoidance domain-specific factor is discouraged.
