Item Anxiety sensitivity, metacognitions, and generalized anxiety disorder symptoms(2023) Styba-Nelson, Kevin; Penney, AlexanderPrevious research has established that anxiety sensitivity (AS) and metacognitions are both associated with generalized anxiety disorder (GAD). AS consists of social concerns, cognitive concerns, and physical concerns about the negative impact of anxiety symptoms. Metacognitions are thoughts and beliefs about one’s cognitions, and both positive and negative beliefs about worry are key metacognitions in GAD. This study examined the unique contributions of these metacognitions and facets of AS on worry severity and GAD symptoms. An undergraduate sample (N = 150) completed self-report questionnaires of GAD symptoms, worry severity, AS, and metacognitions. Moderate to strong bivariate correlations were found between all variables. The results of multiple regression equations revealed that social concerns of AS, positive beliefs about worry, and negative beliefs about worry were uniquely associated with both GAD symptoms and worry severity. Additionally, negative beliefs about worry remained the only significant predictor of GAD symptoms when controlling for worry severity. These findings agree with previous research that negative beliefs about worry are a robust predictor of GAD symptoms. This serves to further highlight negative beliefs about worry’s connection with GAD, and indicates that therapists may wish to focus on negative beliefs about worry more than AS when treating GAD.Item Are metacognitions part of the common core cognitive vulnerability?(2023) Styba-Nelson, Kevin; Penney, AlexanderHong and colleagues have recently argued that anxiety and depression-related constructs like anxiety sensitivity (AS), intolerance of uncertainty, and ruminative style may be components of a broad general negative repetitive thinking style, known as the common core cognitive vulnerability. Despite similarities between AS and dysfunctional metacognitive beliefs, particularly between AS cognitive concerns and negative metacognitive beliefs about worry, there has been a lack of research examining commonalities between them. Examining AS and metacognitions together may help indicate if dysfunctional metacognitions should be considered another component of this larger cognitive vulnerability. In this study, an undergraduate sample (N=350) completed self-report questionnaires of AS and metacognitive beliefs. AS was assessed using the Anxiety Sensitivity Index-3 (ASI-3) with its three subscales measuring physically, socially, and cognitively focused concerns. Metacognitive beliefs were assessed using the Metacognition Questionaire-30 (MCQ-30), with its five subscales for positive beliefs about worry, negative beliefs about worry, cognitive confidence, need to control thoughts, and cognitive self-consciousness. An exploratory principal component analysis revealed the model of best fit was a one factor solution, with all eight subscales loading onto the factor. The cognitive subscale of the ASI-3 had the strongest loading on this factor, followed by negative beliefs about worry, and ASI-3 physical concerns. These findings demonstrate that marked similarities exist in the constructs that make up the subscales of the ASI-3 and MCQ-30. Further, the findings suggest that dysfunctional metacognitions may be another aspect of the proposed common core cognitive vulnerability. Implications for treatment and future research will be discussed.Item Do metacognitions contribute to health anxiety when controlling for OCD comorbidity?(2023) Styba-Nelson, Kevin; Byam, Layton; Penney, AlexanderPrevious research has found that dysfunctional metacognitive beliefs about health are associated with health anxiety (HA), even when controlling for depression, anxiety, and anxiety sensitivity. Obsessive-compulsive disorder (OCD) overlaps with HA, but OCD symptoms have not been controlled for in prior studies that examined metacognitive beliefs about health. The current study examined if metacognitive beliefs about health remain associated with HA when OCD and anxiety sensitivity were accounted for. An undergraduate sample (N = 400) completed online self-report questionnaires of OCD symptoms, anxiety sensitivity, metacognitive beliefs about health, and HA. OCD symptoms, anxiety sensitivity, and metacognitive beliefs about health all showed moderate to strong bivariate correlations with HA. A hierarchical multiple regression was conducted where OCD symptoms were entered in the first step, anxiety sensitivity was entered in the second step, and metacognitive beliefs were entered in the last step. Metacognitive beliefs about the uncontrollability of illness-related thoughts, along with OCD symptoms and anxiety sensitivity about physical concerns, were found to be uniquely predictive of HA. These findings support previous research establishing a link between metacognitive beliefs and HA, and expand upon them by suggesting the relationship is not accounted for by OCD symptoms.Item Do metacognitions have a moderating role in GAD? An investigation with neuroticism, anxiety sensitivity, and intolerance of uncertainty(2024) Styba-Nelson, Kevin; Penney, AlexanderThere are many cognitive thought patterns and individual factors that are known to underly the persistent and wide spread worrying of individuals with GAD. This includes the personality trait of neuroticism, as well as the maladaptive cognitions of AS, and IU. Metacognitive beliefs about worry, people’s beliefs about the impact and controllability of worrying, are also known to be a substantial factor in GAD. The present studies sought to investigate this possible moderating effect, and evaluate its impact on individuals’ worry severity and symptoms of GAD. The first of these studies (N = 573) investigated the moderating effect of metacognitions on the relationships anxiety sensitivity has with worry severity and GAD in an undergraduate sample. The second of these studies (N = 627) expanded upon the first. It investigated the indirect pathways from neuroticism to worry severity and GAD, through anxiety sensitivity and intolerance of uncertainty. Its primary focus was to then investigate if these indirect pathways would be moderated by metacognitive beliefs. Overall, these studies did not conclude that metacognitions play a moderating role in the relationships neuroticism, anxiety sensitivity, and intolerance of uncertainty have with worry severity and GAD. Despite this, it was still found that anxiety sensitivity and intolerance of uncertainty were significant mediators in the indirect pathways that connect neuroticism to worry severity and GAD. This would suggest that future research may wish to further investigate these mediational pathways, and possibly incorporate metacognitions as mediating rather than moderating variables.Item Examining anxiety sensitivity, metacognitions, and anxiety symptoms(2023) Styba-Nelson, Kevin; Penney, AlexanderGeneralized anxiety disorder (GAD) is defined by chronic, distressing worry regarding multiple areas of a person’s life. One thought pattern that is known to contribute to GAD symptoms is anxiety sensitivity (AS). AS can be thought of as the fear of anxiety and its consequences. Two other thought patterns that contribute to GAD are positive beliefs about worry (PBW) and negative beliefs about worry (NBW). PBW refers to beliefs that worry is a positive tool for things like problem solving. NBW refers to beliefs that worrying is harmful or uncontrollable. While both PBW and NBW are related to GAD, NBW’s relationship is much stronger. In Fall 2022, I conducted a study that examined how PBW and NBW interact with AS to contribute to GAD. Given NBW’s much stronger relationship with GAD than PBW, I predicted that only NBW would interact with AS to contribute to GAD symptoms. Data from 573 student self-reports showed that AS, NBW, and PBW all independently related to GAD without relying on one another. However, these findings may have been affected by an abnormally anxious student sample. Given this, a second running of this study with a non-student sample is planned, which will additionally examine how fears of uncertain future events, as well as tendencies to experience negative emotions, are associated with GAD. While these preliminary findings were unexpected, they provide a valuable foundation for future research, and may be relevant to understanding how different thought patterns can contribute to the same disorder.Item Neuroticism to GAD: The influence of thought processes and metacognitions(2024) Styba-Nelson, KevinThere are many cognitive thought patterns and individual factors that are known to underly the persistent and wide spread worrying of individuals with GAD. This includes the personality trait of neuroticism, as well as the maladaptive cognitions of AS, and IU. Metacognitive beliefs about worry, people’s beliefs about the impact and controllability of worrying, are also known to be a substantial factor in GAD. The present studies sought to investigate this possible moderating effect, and evaluate its impact on individuals’ worry severity and symptoms of GAD. The first of these studies (N = 573) investigated the moderating effect of metacognitions on the relationships anxiety sensitivity has with worry severity and GAD in an undergraduate sample. The second of these studies (N = 627) expanded upon the first.

Despite this, it was still found that anxiety sensitivity and intolerance of uncertainty were significant mediators in the indirect pathways that connect neuroticism to worry severity and GAD. This would suggest that future research may wish to further investigate these mediational pathways, and possibly incorporate metacognitions as mediating rather than moderating variables.Item Ugh! Don’t get sick: disgust sensitivity contributes to health anxiety(2023) Styba-Nelson, Kevin; Byam, Layton; Penney, AlexanderHealth anxiety (HA) refers to persistent fears about experiencing or developing severe illnesses. HA has been associated with obsessive-compulsive disorder (OCD) and with dysfunctional health beliefs. However, some research has also indicated that the primary emotion of disgust may be associated with HA. The present study sought to investigate if a relationship exists between HA and disgust, even when controlling for OCD symptoms and dysfunctional metacognitive beliefs about health. An undergraduate sample (N=552) completed online self-report questionnaires of HA, OCD symptoms, health-related-metacognitions, disgust propensity, and disgust sensitivity. Disgust propensity refers to the likelihood that a person will experience disgust, while disgust sensitivity refers to how strongly a person experiences disgust. OCD symptoms, health-related-metacognitions, disgust propensity, and disgust sensitivity all showed moderate to strong bivariate correlations with HA. A hierarchical multiple linear regression was conducted with HA as the dependent variable, OCD symptoms entered in the first step, health-related-metacognitions in the second step, and disgust propensity and disgust sensitivity in the third step. It was found that disgust sensitivity, but not disgust propensity, was a unique predicter of HA, even when controlling for both OCD symptoms and health-related-metacognitions. This finding suggests a person’s sensitivity to the emotion of disgust may play a role in HA, and that this relationship is not better accounted for by OCD symptoms or health-related-metacognitions. Techniques targeting disgust sensitivity could be a valuable addition to therapies aimed at HA, with interoceptive exposure to the feelings of disgust being a possible area for future research.
