The dementia score is an instrument used to assess disorders of
cognitive performance related to dementia. It is a subjective
assessment of the study participant made by the interviewer, based on
impressions gained from the observation of the participant. The
interviewers were given special training for this rating using
clinical examples.
The dementia score is composed of the screening-variables
for psychopathological diagnosis listed in the table below. The items
were selected from the AMDP system (Helmchen, 1979) on the basis of
their relevance for the psychiatric assessment of elderly
participants and their ability to be operationalized for assessment
by a lay person.
When coding their observations, interviewers chose from five
possible answers on a probability scale:
1 = "certainly not", i.e., the symptom is certainly not
present.
2 = "probably not", i.e., it is not certain that the symptom is not
present.
3 = "probably", i.e., it is not certain that the symptom is
present.
4 = "certainly", i.e., the symptom is present.
5 = "not ascertainable", i.e., no information on the presence/absence
of the symptom in question could be gained (e.g. in short contacts or
telephone contacts). For T6 this variable was coded "8".
The lay interviewers were not asked to make an assessment of
symptom severity due to the fact that even expert judgments can be
unreliable here. A symptom only counted as observed if it was clearly
noticeable for a lay assessor. To this end, a brief description of
each symptom was provided. In order for the items to be assessed
properly, an observation period of at least 15 minutes was necessary.
If the first contact was shorter than this, the relevant items of the
observation protocol could only be filled in if a longer contact took
place at a later date.
Even if the interviewer was aware of the reason behind an observed
symptom, this was not taken as an assessment criterion, except where
explicitly mentioned in the brief description of the item (e.g. false
teeth missing for articulatory problems).
In the calculation of the dementia score, a temporary weighting
was given to the importance of the symptom for the clinical diagnosis
of dementia according to clinical criteria of item weighting.
