Nolen-Hoeksema and Watkins (2011, this issue) propose a useful model for thinking about transdiagnostic processes involved in mental disorders. Here, we argue that their model is naturally compatible with a network account of mental disorders, in which disorders are viewed as sets of mutually reinforcing symptoms. We show that network models are typically transdiagnostic in nature, because diff...

Youth with autism spectrum disorder often struggle to cope with co-occurring anxiety, depression, or anger, and having both internalizing and externalizing symptoms is a common clinical presentation. A number of authors have designed cognitive-behavioral interventions to address transdiagnostic factors related to multiple emotional problems, although none have applied this focus to youth with A...

OBJECTIVE In psychiatric patients, comorbidity tends to be the rule, rather than the exception. This is especially true for patients with social anxiety disorder (SAD), but research on the implications of diagnostic status has been limited. This study aimed to examine the frequency of SAD as: (1) the only diagnosis, (2) a principal diagnosis with comorbid conditions, or (3) a comorbid condition...

The current study used longitudinal data to examine the role of emotional awareness as a transdiagnostic risk factor for internalizing symptoms. Participants were 204 youth, ages 7 to 16, who completed assessments every three months for a year. Results from hierarchical mixed effects modeling indicated that low emotional awareness predicted both depressive and anxiety symptoms for up to one yea...

BACKGROUND There is a need for qualitative research to help develop case conceptualisations to guide the development of Metacognitive Therapy interventions for Eating Disorders. METHOD A qualitative study informed by grounded theory methodology was conducted involving open-ended interviews with 27 women aged 18-55 years, who were seeking or receiving treatment for a diagnosed ED. RESULTS Th...

Epidemiological studies indicate a combined contribution of genetic and environmental factors, mainly exposure to adverse life events, in the risk for psychiatric disease. Understanding how adverse life events interact with genetic predisposition on the molecular level to shape risk and resilience to psychiatric disorders may yield important insight into disease mechanism. Using the example of ...

IMPORTANCE Multivariable comorbidity research indicates that many common mental disorders are manifestations of 2 latent transdiagnostic factors, internalizing and externalizing. Environmental stressors are known to increase the risk for experiencing particular mental disorders, but their relationships with transdiagnostic disorder constructs are unknown. The present study investigated one such...

Transdiagnostic approaches to cognitive behaviour therapy (TCBT) of anxiety disorders have drawn increasing interest and empirical testing over the past decade. In this paper, we review evidence of the overall efficacy of TCBT for anxiety disorders, as well as TCBT efficacy compared with wait-list, treatment-as-usual, and diagnosis-specific cognitive behaviour therapy (CBT) controls. A total of...

This paper is concerned with the psychopathological processes that account for the persistence of severe eating disorders. Two separate but interrelated lines of argument are developed. One is that the leading evidence-based theory of the maintenance of eating disorders, the cognitive behavioural theory of bulimia nervosa, should be extended in its focus to embrace four additional maintaining m...

The high rate of comorbidity among mental disorders has driven a search for factors associated with the development of multiple types of psychopathology, referred to as transdiagnostic factors. Rumination is involved in the etiology and maintenance of major depression, and recent evidence implicates rumination in the development of anxiety. The extent to which rumination is a transdiagnostic fa...
