Aversive Reactivity: A Transdiagnostic Functional Bridge Between Neuroticism and Avoidant Behavioral Coping

Aversive reactivity to negative affect has been described as a transdiagnostic mechanism that links distal temperamental vulnerabilities to clinically relevant behaviors. However, the abundance of constructs reflecting aversive reactivity has resulted in a proliferation of models that may ultimately be redundant. We performed a circumscribed review of studies measuring associations between six constructs – anxiety sensitivity, experiential avoidance, distress intolerance, intolerance of uncertainty, thought-action fusion, and negative urgency – and ten relevant coping behaviors. Results suggested that most constructs were measured in relation to a limited number of coping behaviors. Additionally, constructs were most often measured in isolation, rather than with similar constructs. Implications and suggestions for future research and treatment are discussed.

Thought-action fusion and inflated responsibility in psychopathology

<p>The aim of the current research was to investigate the presence and roles of inflated responsibility and thought-action fusion in psychopathology. The three underlying research themes were to examine the relationship between thought-action fusion and inflated responsibility, the roles that they play in psychopathology, and the possible etiology of these types of beliefs. It is proposed that these responsibility beliefs are not specific to obsessive compulsive disorder, as commonly assumed, and that they play important roles in the maintenance of a range of psychological symptoms. This thesis presents the results of four studies. The first study was designed to investigate the presence of Thought-Action Fusion (TAF) and Inflated Responsibility (IR) alongside symptoms of depression, anxiety, and obsessive-compulsive disorder, with thought suppression playing an intermediary role. Study 2 examined the interaction between responsibility beliefs and locus of control on obsessive-compulsive symptoms with non-clinical and clinical participants. The third study focussed on the etiology of responsibility beliefs, taking Salkovskis, Shafran, Rachman, and Freeston’s (1999) theory of Pathways to Inflated Responsibility and empirically testing this with both clinical and non-clinical samples. Study 4 focussed on the relationship between responsibility beliefs and religiosity, using participants of Protestant Christian beliefs and Atheists. These studies collectively show that Thought-Action Fusion and Inflated Responsibility are both important and contributing factors in psychopathology, especially playing a part in the maintenance of symptoms and feelings of distress. Results indicated that while TAF tends to be specific to obsessive compulsive symptoms, IR is more of a general cognitive bias. Results also indicate that critical experiences in one’s life can lead to biases in responsibility beliefs. Additionally, results show that these biases are not always indicative of psychopathology when they are acceptable within a particular set of morals, for example religion. These findings are of both theoretical and clinical significance because they add to the growing understanding of TAF and IR in psychopathology. The current research was conducted with observational, self-report measures; further research using longitudinal studies is needed for more clarity on causality.</p>

The Development and Preliminary Validation of a New Measure of Scrupulosity: The Scrupulous Thoughts and Behaviours Questionnaire

The purpose of this study was to develop and provide a preliminary validation of a new measure of scrupulosity, the Scrupulous Thoughts and Behaviours Questionnaire (STBQ). More specifically, the STBQ was designed to assess a range of scrupulosity-related thoughts/obsessions and behaviours/compulsions. Following item development, a sample of non-referred college students completed the STBQ along with numerous validation measures. Based on factor analyses, a two-factor solution was retained. The first factor consisted of items that measure scrupulosity-themed obsessions and thoughts, and the second factor consisted of items that measure scrupulosity-themed compulsions and related behaviours. Support was found for the validity of STBQ, as both subscales were significantly and positively associated with measures of relevant constructs, including the Pennsylvania Inventory of Scrupulosity-Revised, the only other self-report measure of scrupulosity, thought–action fusion, religiosity, and obsessive–compulsive disorder symptoms. As the first known self-report measure to assess scrupulosity obsessions and compulsions, the STBQ has a potential utility in clinical practice and research.

Thought-Action Fusion as Predictors of Obsessive-Compulsive Symptom Dimensions

Objective There have been several studies investigating the relationships between dysfunctional beliefs and obsessive-compulsive (OC) symptoms in obsessive-compulsive disorder (OCD). However, studies about the relationships between dysfunctional beliefs, especially thought-action fusion (TAF), and OC symptom dimensions have been scarce. Therefore, this study examined to what extent and how TAF subcomponents account for unique variability in four OC symptom dimensions.Methods Sixty-five patients with OCD and 45 healthy controls aged between 18 and 30 years completed measures for OC symptom dimensions, OC symptoms, and dysfunctional beliefs such as TAF, trait-guilt, and inflated responsibility.Results Three facets of TAF were exclusively associated with two symptom domains, namely, responsibility for harm and unacceptable thoughts, and explained the additional but small amount of variance to predict these two domains. In particular, the likelihood-others TAF positively predicted the unacceptable thoughts domain, whereas the likelihood-self TAF negatively predicted the aforementioned domain. For OC symptoms measured by the OC Inventory, no TAF components predicted the corresponding obsessing and mental neutralizing symptoms.Conclusion This study provides supporting evidence that the three TAF subcomponents may be differently associated with certain OC symptom dimensions, and a dimensional approach may complement typical symptom-oriented OC measures.
