To complement the evidence-based practice paradigm, the authors argued for a core outcome measure to provide practice-based evidence for the psychological therapies. Utility requires instruments that are acceptable scientifically, as well as to service users, and a coordinated implementation of the measure at a national level. The development of the(More)
This paper examines the estimation of a global nonlinear gas turbine model using NARMAX techniques. Linear models estimated on small-signal data are first examined and the need for a global nonlinear model is established. A nonparametric analysis of the engine nonlinearity is then performed in the time and frequency domains. The information obtained from(More)
The authors investigated factors that may determine whether perpetrators of violent crime develop intrusive memories of their offense. Of 105 young offenders who were convicted of killing or seriously harming others, 46% reported distressing intrusive memories, and 6% had posttraumatic stress disorder. Intrusions were associated with lower antisocial(More)
The Crown-Crisp Experiential Index (CCEI) was designed as a measure of neurotic symptomatology. The tendency has been to report upon its six separate scales and to ignore the total score. We report on the use of the CCEI in a detailed interview study of 208 40-49-year-old women from a local community and 40 patients of the same age range and sex from a(More)
A replication of an American study of body shape preference was conducted in a group of 218 Arab students attending the American University in Cairo, Egypt. Arab female students felt their ideal shape to be significantly thinner than their current shape, while male students did not. Hence the appraisal of body shape shows gender differences in Egypt(More)
BACKGROUND Measurement is the foundation of evidence-based practice. Advances in measurement procedures should extend to psychotherapy practice. AIMS To review the developments in measurement relevant to psychotherapy. METHOD Domains reviewed are: (a) interventions; (b) case formulation; (c) treatment integrity; (d) performance (including adherence,(More)
The linear multivariable modelling of an aircraft gas turbine is presented. A frequency-domain identification method is employed to estimate a family of models from engine data at a range of operating points. It is found that the fuel feed to shaft speed dynamics can be represented by second-order models. This matches the results obtained for the(More)
