Betrouwbaarheidsaspecten van de Present State Examination in vier verschillende populaties
Apart from being used as diagnostic instrument in clinical settings the Present State Examination is also employed in open populations to assess the prevalence of psychiatric symptoms. In a pilot study we examined two aspects of the reliability of the PSE: its interraterreliability and its reliability in distinct populations. With regard to the first aspect independent judges showed a fair amount of agreement. The reliability proved not to be the same in the four patient categories. With the patients of general practitioners and with those from a clinic for neurotics the interview reliability was better than with patients from a general mental hospital. With non-patients too the reliability was acceptable. Our results tend to confirm internationally known research findings. The PSE proves to be adequate for research in a general population.
