![]() Curated stories on UX, Visual & Product Design. We believe designers are thinkers as much as they are makers. Both measures can be used in future studies to retrospectively assess associations between childhood abuse and psychotic phenomena, but time-permitting, the CECA is preferable as it provides additional important contextual details of abuse exposure. Cases studies from professionals and students who decide to share their process with the world. Case studies Use the filter below to explore examples of how UCL is helping to achieve the UNs Sustainable Development Goals. For physical abuse, convergent validity was slightly lower in cases compared with controls. In a sample of 374 cases and 301 controls, we collected extensive data on childhood adversities, in particular household discord, various forms of abuse and bullying, and putative confounders. Method: CAPsy is population-based first-episode psychosis case-control study in the UK. For reports of sexual and emotional abuse, we found fair levels of agreement between CECA and CTQ ratings in both groups (kappa coefficients 0.43–0.53), moderate to high sensitivity and specificity, and reasonably high convergent validity (tetrachoric correlations of 0.78–0.80). The Caerphilly Prospective Study (CAPS) was set up by the former MRC Epidemiology Unit South Wales to study cardiovascular disease in the United Kingdom. Aims: Using detailed data from the Childhood Adversity and Psychosis (CAPsy) study, we sought to address these gaps and examine in detail associations between a range of childhood adversities and psychotic disorder. ![]() ![]() In a sample of 234 cases with first-episode psychosis and 293 controls, we found no strong evidence that the validity of the two measures differed between cases and controls. Data from the Childhood Adversity and Psychosis (CAPsy) study were used to examine the accuracy, strength of agreement, and convergent validity of two distinct retrospective measures of childhood abuse: a self-report questionnaire (the Childhood Trauma Questionnaire CTQ) and a comprehensive interview (the Childhood Experiences of Care and Abuse schedule CECA). ![]() A case study helps in bringing the understanding of a complex issue or object. They can be produced following a form of research. One way to establish if any substantial bias may exist is to examine whether the concordance of reports of childhood abuse established from retrospective self-report methods versus more comprehensive interviewer-rated assessments differ between individuals with psychosis and controls. A case study is research method that involves an up-close, in-depth and detailed investigation of a subject of study and its related contextual position. The typical reliance on self-report questionnaires in retrospective case-control studies of childhood abuse and psychotic disorders has been criticised, due to the potential for recall bias associated with, amongst other factors, cognitive impairments and detachment from reality, among individuals with psychosis. ![]()
