    Differentiating the roles of intolerance of uncertainty and negative beliefs about worry across emotional disorders
    (2020) Penney, Alexander; Rachor, Geoffrey S.; Deleurme, Kendall A.
    Background: Researchers have examined intolerance of uncertainty (IU) and negative beliefs about worry (NBW) in emotional disorders. However, the distinct relationships of IU and NBW remain unclear. We examined IU and NBW across emotional disorders, controlling for overlapping symptoms. We also explored prospective and inhibitory IU. Methods: A sample of 565 undergraduates completed measures of IU and NBW, as well as measures of generalized anxiety, depression, social anxiety, panic, post-traumatic stress, obsessive-compulsive, and illness anxiety disorder symptoms. Regression analyses were used to determine which factors were uniquely associated with symptoms of each disorder. Results: Both IU and NBW were associated with generalized anxiety and social anxiety disorder symptoms. IU was also associated with obsessive-compulsive disorder symptoms and negatively associated with panic disorder symptoms. NBW was also associated with depression. Neither IU now NBW were associated with post-traumatic stress or illness anxiety disorders. Prospective and inhibitory IU also had differential associations with the emotional disorders. Conclusions: Our results indicate that IU and NBW, while transdiagnostic, are differentially associated with emotional disorder symptoms. Our results also support the discriminant validity of prospective and inhibitory IU.

    Generalized anxiety disorder: does the emotion dysregulation model predict symptoms beyond the Metacognitive Model?
    (2022) Deleurme, Kendall A.; Parkinson, Sydney; Penney, Alexander
    While the Metacognitive Model (MCM) of generalized anxiety disorder (GAD) is well-established, the Emotion Dysregulation Model (EDM) of GAD has received less attention. This study examined whether the EDM helps explain GAD above and beyond the MCM. The influence of gender was also explored. A non-clinical university sample (N = 626) completed measures of GAD symptoms, worry severity, the MCM, and the EDM. In support of the EDM, it was found that fear of depression predicted GAD symptoms for men, while fear of anxiety predicted GAD symptoms for women. However, across genders, the strongest predictor of GAD symptoms and worry severity was negative beliefs about worry. While these findings support the MCM view that holding the beliefs that worry is harmful and dangerous is the strongest predictor of GAD overall, incorporating aspects of the EDM into our understanding and treatment of GAD may be beneficial.

    The implications of high-conflict divorce on adult–children: five factors related to well-being
    (2021) Radetzki, Phillip A.; Deleurme, Kendall A.; Rogers, Sean
    Offspring of divorce are generally more vulnerable to negative mental health outcomes than counterparts of intact marriages. However, not all cases of divorce are equivalent. The present study aimed to contribute to divorce literature by investigating the role of interparental conflict during the divorce process on offspring well-being. A convenience sample of 144 adult undergraduates from divorced families completed questionnaires pertaining to perceptions of interparental conflict and psychological well-being, interpersonal competence, irrational beliefs, materialistic orientations, and emotion dysregulation. Perceptions of interparental conflict during divorce positively correlated with irrational thinking and emotion dysregulation, and negatively correlated with psychological well-being and interpersonal competence. A MANOVA revealed that participants' perceptions of interparental conflict had significant predictive power on all factors of interest except materialism. In the model, interparental conflict had the greatest effect on emotion dysregulation. Participants with perceptions of high interparental conflict had greater impairments in all variables (except materialism, which was non-significant) compared to the low perception group. They also presented greater impairment in interpersonal competence, emotion regulation, and rational thinking than the medium perception group. Overall, the results suggest interparental conflict during divorce is relevant to offspring outcomes, perhaps particularly within emotion regulation.

    Models of generalized anxiety disorder: does the emotion dysregulation model aid understanding?
    (2017) Deleurme, Kendall A.; Penney, Alexander
    While models of generalized anxiety disorder (GAD) are available, the literature continues to explore and expand upon the different conceptualizations. Among these models, one of the most recent is the Emotion Dysregulation Model (EDM). According to the EDM, individuals with GAD have issues understanding, expressing, and managing emotions. The EDM proposes that individuals with GAD experience the following: emotional hyperarousal, involving low emotional thresholds; poor understanding of emotions, including problems with describing and labelling; negative attitudes towards emotions; and unsuccessful emotion regulation and management strategies. However, there is a lack of research providing support for the utility of the EDM. Furthermore, a gap exists in the literature comparing the EDM to more established models. The proposed study extends the current literature by examining whether the EDM helps explain GAD symptoms when compared to a well-established model of GAD, the Metacognitive Model (MCM). The MCM emphasizes that individuals with GAD have negative beliefs about the dangerousness and uncontrollability of worry. Several self-report measures previously used in research of the EDM and the MCM will be administered to non-clinical university participants (N = 400) to investigate which measures uniquely predict GAD symptoms. The proposed study hypothesizes the following: GAD symptoms will positively correlate with emotion dysregulation; GAD symptoms will positively correlate with negative beliefs about worry; and emotion dysregulation will predict GAD symptoms independent of negative beliefs about worry. Expected findings have implications for treatment of GAD, encouraging an approach focusing on emotion psychoeducation and development of effective emotional regulation strategies.
