Abstract
This thesis investigates the p-factor, as the shared variance common to the many forms of psychopathology (Caspi et al, 2014). It does so by reviewing its possible prognostic value, and as part of a factor analytic approach to examining the relationship between veteran father’s psychopathology and that of their children. It is a joint thesis with ‘A mixed-method exploration of the impact of PTSD in UK military veterans and their families’ (Jones, 2020). A growing evidence-base has identified the p-factor as accounting for one’s vulnerability to mental disorder, as well as comorbidity, severity and chronicity (Caspi & Moffit, 2018). Whilst it is established as a statistical finding in psychopathology research, uncertainty remains over the meaning of the finding and the nature of the possible construct. Part 1, the literature review, systematically reviews longitudinal studies that can assess the possible future outcomes following measurement of the p-factor. Fourteen studies were identified and provide strong indication of the p-factor’s prognostic value, across a range of outcome domains. A bifactor analytic framework was subsequently used to investigate mental disorder of veterans and their children. Part 2, the empirical paper, used self-report psychopathology data on veteran fathers and parent-report data on their children to examine the relationship between the two. Bifactor models were found to fit the data best and findings suggested there was an association between father’s psychopathology and child’s psychopathology. Although father’s reflective functioning was associated with children’s psychopathology, the findings suggest it was a non-significant mediator between father’s p and child p.
