| Opplysninger | Global ratings of change were obtained from 17 clinicians on eight patients, as though participating in an antidementia drug trial.Simultaneous rating was made possible by the use of videotaped semi-standardized interviews, and clinical change was simulated by providing raters with adjusted initial assessment documentation representing the situation 6 months earlier. In a second study, seven more ratings were obtained on the two patients who had commanded best and worst agreement in order to clarify important variables for levels of agreement. The main finding was that levels of interrater agreement on a global rating of change (which included carer information) varied widely from patient to patient. An important contributor to this variation was carer information. The order in which information for rating had been presented was found to be of overriding importance; if carer information was presented before patient information,considerably higher levels of agreement were achieved on the global rating than if the reverse order was used.
