The Intolerance of Uncertainty Model was initially developed as an explanation for worry within the context of generalized anxiety disorder. However, recent research has identified intolerance of uncertainty (IU) as a possible transdiagnostic maintaining factor across the anxiety disorders and depression. The aim of this study was to determine whether IU(More)
Researchers have recently suggested that the commonalities across the emotional disorders outweigh the differences, and thus similar treatment principles could be applied in unified interventions. In this study, the authors used a benchmarking strategy to investigate the transportability of cognitive-behavioral therapy (CBT) for anxiety and depression to(More)
AIMS The aim of study 1 was to develop a three-factor Approach and Avoidance of Alcohol Questionnaire (AAAQ), designed to assess mild and intense inclinations to drink, as well as inclinations to avoid drinking. The aims of study 2 were to cross-validate the AAAQ with an independent sample and to test the goodness-of-fit of three models of craving for(More)
Homework or between-session learning has long been considered an essential aspect of effective cognitive behaviour therapy. However, it has received relatively less empirical attention than other components of cognitive behaviour therapy. In general, studies have found that homework completion is predictive of outcome in psychotherapy. However, the amount(More)
BACKGROUND Repetitive negative thinking (RNT) increases vulnerability to multiple anxiety and depressive disorders and, as a common risk factor, elevated RNT may account for the high levels of comorbidity observed between emotional disorders. The aims of this study were to (a) compare two common forms of RNT (worry and rumination) across individuals with(More)
The Self-Regulatory Executive Function model [S-REF; Wells, A., & Matthews, G. (1996). Modelling cognition in emotional disorder: the S-REF model. Behaviour Research and Therapy, 34, 881-888] proposes that metacognitive beliefs, inflexible self-focused attention, and perseverative thinking (rumination and worry) play an important role in maintaining(More)
This study used a benchmarking strategy to investigate the transportability of cognitive behavioural group therapy (CBGT) for social phobia to a community mental health clinic. The influence of common exclusion criteria on effect sizes was also examined. Patients (N=153) attended seven 4-h sessions of CBGT, which resulted in significant reductions in(More)
Evidence is accumulating that intolerance of uncertainty (IU) may be a transdiagnostic maintaining factor across the anxiety disorders and depression. However, psychometric studies of the most commonly used measure of IU have typically used undergraduate students, and the factor structure has been highly inconsistent. Previous studies have also tended to(More)
Intolerance of uncertainty (IU) has been identified as a potential maintaining factor for generalised anxiety disorder; however, there is a growing evidence to suggest that IU may contribute to other anxiety and depressive disorders. Moreover, certain components of IU (namely prospective and inhibitory IU) have been shown to be differentially associated(More)
There is a strong link between perfectionism and eating disorders, yet little research to date has examined mediators of this relationship. The aim of this study was to investigate the mediating effect of anxiety on the relationship between perfectionism and eating pathology in a clinical sample (N = 370, M age = 25.04, 99 % female) of treatment-seeking(More)
