Gliederung

Text

Background: The WHOQOL-OLD - an intercultural comparable WHO instrument for measuring subjective quality of life (qol) - is a 24-item 6-facet add-on module which can be used with the WHOQOL-BREF or the WHOQOL-100 for assessment of qol in older adults. A great number of research centres from different cultures (WHOQOL-OLD group) developed this questionnaire under the sponsorship of the WHO. The WHOQOL-OLD applies to healthy people as well as to patients with somatic or psychiatric diseases, 60 years and older.

The aim of the study was to investigate the measurement characteristics of the WHOQOL-OLD in the German population of older people depending on the cognitive status (no cognitive impairment vs. mild cognitive impairment (MCI)) as well as on other individual characteristics. The main question was: Does MCI have an effect on the assessment of subjective qol?

Method: In a survey on 1000 German older adults (60+ yrs.), the WHOQOL-OLD was assessed. Participants were also investigated with a measure on cognitive status (DemTect). In order to asses both the dimensionality of the instrument and the sensitivity of the prescriptive forms of answering to individual characteristics Partial Credit Models as well as Mixture General Diagnostic Models are employed. Uniform and non-uniform differential item functioning is explored by means of explanatory IRT models. The impact of the cognitive status on QoL, as well as its effect as a source of DIF in the general population is investigated.

Results: Results of the analyses will be presented.

Discussion/Conclusion: Discussion will be presented.
