Background: Dimensional models of psychopathology are increasingly common and there is evidence for the existence of a general dimension of psychopathology ('p'). The existing literature presents two ways to model p: as a bifactor or as a higher-order dimension. Bifactor models typically fit sample data better than higher-order models, and are often selected as better fitting alternatives but there are reasons to be cautious of such an approach to model selection. In this study the bifactor and higher-order models of p were compared in relation to associations with established risk variables for mental illness. Methods: A trauma exposed community sample from the United Kingdom (N = 1051) completed self-report measures of 49 symptoms of psychopathology. Results: A higher-order model with four first-order dimensions (Fear, Distress, Externalising and Thought Disorder) and a higher-order p dimension provided satisfactory model fit, and a bifactor representation provided superior model fit. Bifactor p and higher-order p were highly correlated (r = 0.97) indicating that both parametrisations produce near equivalent general dimensions of psychopathology. Latent variable models including predictor variables showed that the risk variables explained more variance in higher-order p than bifactor p. The higher-order model produced more interpretable associations for the first-order/specific dimensions compared to the bifactor model. Conclusions: The higher-order representation of p, as described in the Hierarchical Taxonomy of Psychopathology, appears to be a more appropriate way to conceptualise the general dimension of psychopathology than the bifactor approach. The research and clinical implications of these discrepant ways of modelling p are discussed. [ABSTRACT FROM AUTHOR]

The ICD-11 reconceptualized Posttraumatic Stress Disorder (PTSD) as a narrowly defined fear-based disorder, and introduced Complex PTSD (CPTSD) as a new diagnosis comprised of PTSD symptoms and symptoms of 'Disturbances in Self-Organization' (DSO) that are more reflective of general dysphoria. Previous research suggests that PTSD symptoms mediate the association between childhood trauma and physical health problems, including cardiovascular disease. No study has yet assessed how posttraumatic stress symptoms, as outlined in the ICD-11, influence the association between childhood trauma and somatic problems in adulthood.Objective: This cross-sectional descriptive study examined whether PTSD and DSO symptoms mediated the associations between childhood physical and sexual abuse and childhood emotional abuse and neglect and somatic problems and cardiovascular diseases (CVD) load in adulthood.Methods: General adult population samples from Ireland (N = 1020) and the United Kingdom (N = 1051) completed self-report questionnaires online.Results: Structural equation modelling results indicated that PTSD and DSO symptoms fully mediated the association between both forms of childhood trauma and somatic problems, and that PTSD symptoms but not DSO symptoms fully mediated the association between childhood trauma and CVD load.Conclusion: Psychological interventions that effectively treat CPTSD symptoms may have the added benefit of reducing risk of physical health problems.

Background: Media coverage on mental health problems has been found to vary by newspaper type, and stigma disproportionately affects people with mental illness by diagnosis., Objective: This study investigated the relationships between types of UK national newspaper (tabloid vs. broadsheet), illness classification (SMI-severe mental illnesses vs. CMD-common mental disorders), and stigmatising coverage of mental disorders, and whether these relationships changed over the course of the Time to Change anti-stigma programmes in England and Wales., Methods: Secondary analysis of data from a study of UK newspaper coverage of mental illness was performed. Relevant articles from nine UK national newspapers in 2008-11, 2013, 2016 and 2019 were retrieved. A structured coding framework was used for content analysis. The odds an article was stigmatising in a tabloid compared to a broadsheet, and about SMI compared to CMD, were calculated. Coverage of CMD and SMI by newspaper type was compared using the content elements categorised as stigmatising or anti-stigmatising., Results: 2719 articles were included for analysis. Articles in tabloids had 1.32 times higher odds of being stigmatising than articles in broadsheet newspapers (OR 1.32, 95% CI 1.12-1.55). Odds of stigmatising coverage was 1.72 times higher for articles on SMI than CMD (OR  1.72, 95% CI 1.39-2.13). Different patterns in reporting were observed when results were stratified by years for all analyses. A few significant associations were observed for the portrays of stigmatising elements between tabloid and broadsheet newspapers regarding SMI or CMD., Conclusions: Tailored interventions are needed for editors and journalists of different newspaper types, to include specific strategies for different diagnoses., (© 2021.
