Zusammenfassung
Nach Diskussion der Grenzen der Auswertungsmöglichkeiten psychiatrischer Ordinalskalendaten
(“Scores”) in der herkömmlichen Ein-Rating-pro-Symptom-und-Patient-Situation wird
ein Quantifizierungsverfahren vorgeschlagen, das auf der Basis der audiovisuellen
psychiatrischen Technik möglich wird. Bei Anwendung dieser Technik können die aus
der Viele-Ratings-pro-Symptom-und-Patient-Situation resultierenden Daten parametrischen
statistischen Auswertungsverfahren unterzogen werden. Damit wird eine Informationsausschöpfung
möglich, die derjenigen bei Anwendung der bei Scores notwendigen nicht-parametrischen
Verfahren überlegen ist.
Summary
Observational data from psychiatric patients are usually of the ordinal scale type.
Therefore, in the traditional one-rating-per-symptom-and-patient-situation, the resulting
score value can be analysed only by applying nonparametric statistical methods. These
methods are rather inefficient when – as is usual – there are only four-point-scales
for evaluating the symtoms. Moreover, non-parametric methods are not available as
of yet to take into consideration the often complex structure of data from psychiatric
studies.
This leads to the conclusion that the quantification of ordinal scale type data would
be very desirable in order that parametric statistical methods could be applied. Such
a method of quantification is proposed on the basis of the audiovisual psychiatric
rating technique. Is is shown that the data resulting from the many-ratings-per-symptom-and-patient-situation
can be subjected to parametric statistical methods. In applying the proposed method,
therefore, much better use could be made of and a maximum of information could be
extracted from the data in psychiatric studies.
