Confirmatory factor analysis of a two scale model of the Health of the Nation Outcome Scales (HoNOS) across diagnostic categories

The study examines the fit of a two factor model of the Health of the Nation Outcome scales fo r a large sample of patients referred to mental health services in England . The fit of the model for different diagnostic groups delineated by the Engli sh mental health cluster system is investigated. O verall the fit of the model is excellent at the super cluster level of psychotic disorders, organic disorders and good for non - psychotic disorders. It is, however, not as good at the cluster level

Sex difference in awareness of threat:A meta-analysis of sex differences in attentional orienting in the dot probe task

It has been argued that females are more important to infant survival than males and that this may lead to their increased fear. One way of increasing female survival chances would be to increase their sensitivity to threat. The dot-probe task has been used to investigate attentional bias. In this meta-analysis we combine the results of dot-probe experiments and explicitly examine sex differences in attentional orienting bias. Overall there is little evidence to support the existence of sex differences and these results are considered in terms of evolutionary impact

The Psychometric Evaluation of Human Life Histories:A Reply to Figueredo, Cabeza de Baca, Black, Garcia, Fernandes, Wolf, and Woodley (2015)

A recent critique of Copping, Campbell, and Muncer raised several issues concerning the validity of psychometric assessment techniques in the study of life history (LH) strategies. In this reply, some of our key concerns about relying on aggregated psy- chometric measures are explained, and we raise questions generally regarding the use of higher order factor structures. Responses to some of the statistical issues raised by Figueredo et al. are also detailed. We stand by our original conclusions and call for more careful consideration of instruments used to evaluate hypotheses derived from LH theory

Confirmatory Factor Analysis of WAIS-IV in a Clinical Sample: Examining a Bi-Factor Model

There have been a number of studies that have examined the factor structure of the Wechsler Adult Intelligence Scale IV (WAIS-IV) using the standardization sample. In this study, we investigate its factor structure on a clinical neuropsychology sample of mixed aetiology. Correlated factor, higher-order and bi-factor models are all tested. Overall, the results suggest that the WAIS-IV will be suitable for use with this population
