OBJECTIVE The transdiagnostic cognitive behavioral treatments for treating the coexistence of anxiety and mood disorders received useful empirical supports in the recent years. However, these treatments still have moderate efficacy. Following the improvements and developments in transdiagnostic protocols and considering the importance of repetitive negative thinking as a core transdiagnostic fa...

Our objective was to analyze the relationships between Repetitive negative thinking (RNT), perfectionism and psychological distress. Specifically we wanted to test if RNT mediates the relationship between perfectionism and psychological distress. 788 college students completed self-report questionnaires to evaluate perfectionism trait dimensions [Evaluative concerns (EC) and Positive strivings ...

We explored whether transdiagnostic internet-delivered cognitive behavioural therapy (iCBT) for mixed anxiety and depression effectively reduces repetitive negative thinking (RNT), and whether reductions in RNT and positive metacognitive beliefs mediate symptom improvement during iCBT. Participants with generalized anxiety disorder (GAD), major depressive disorder (MDD), or mixed GAD/MDD diagno...

We describe the treatment of a patient with BN (plus comorbid major depression and generalised anxiety disorder) who completed stage one and stage two of CBTE at a specialist eating disorders outpatient clinic. Despite good compliance with all components of the treatment, the patient did not achieve an early rapid reduction in binge-eating and purging by the stage two progress review and was co...

This study explored spatial navigation alongside several other cognitive abilities that are thought to share common underlying neurocognitive mechanisms (e.g., the capacity for self-projection, scene construction, or mental simulation), and which we hypothesized may be impaired in autism spectrum disorder (ASD). Twenty intellectually high-functioning children with ASD (with a mean age of ~8 yea...

Unhealthy or negative perfectionism has been identified as both a risk and maintaining factor for a range of psychological difficulties. A cross-sectional online study with a predominantly student population (n = 381) investigated cognitive processes suggested to mediate the relationship between unhealthy perfectionism and distress. Hypothesised cognitive processes were assessed using questionn...
