The conclusions of the investigation of Hogarthy (1) a.o. could not be confirmed in an investigation with the same issues in the Netherlands. In the replication of this experiment, done with an inventory of 81 items (Minn. Hartf. Pers. Ass., P.U.K. rating scales, Graffel rating scales), responded by 200 intra- or extramural mental health workers (social workers, psychiatrists, psychologists or nurses), conceptual differences between the intra- and extramural workers could not be demonstrated, as was the case in the Hogarthy investigation. Interesting and tempting for further research were nevertheless other results.
Statistical analysis revealed four clusters. The first factor consisted of items with an evident psychopathological signature. In contrast to the third factor consisting of items with the same evident psychopathological signature, the items of the first factor were those loaded with anxiety, agression and nuisance in the interaction. In the third factor items were clustered that could be named indifferent in the interaction (e.g. depersonalization). The second factor consisted ex -clusively of items out of the P.U.K. rating scales and the Graffel rating scales, both social adjustment rating scales frequently used in the Netherlands. The fourth factor (only four items) concerned the psychopathological 'withdrawal' of schizophrenic behaviour.
Revealing is, that in the concept of mental health workers in the Netherlands about 'mental health' there exist at least three prominent clusters.
First of all the anxiety arousing psychopathological behaviour, secondly the social adjustment, thirdly the indifferent (in the interaction) psychopathological behaviour. This clustering of behavioural items in the concepts of mental health workers appears to be completely independent of theories concerning psychopathological entities of causalities, when mental health workers are asked to judge about the possibilities of a psychiatric patient to reintegrate in society.
