German translation and psychometric testing of the SF-36 Health Survey: Preliminary results from the IQOLA project

Bullinger, Monika·1995·Social Science & Medicine

Abstract

International translation and psychometric testing of generic health outcome measures is increasingly in demand. Following the methodology developed by the International Quality of Life Assessment group (IQOLA) we report the German work with the SF-36 Health Survey. The form was translated using a forward-backward method with accompanying translation quality ratings and pilot tested in terms of translation clarity and applicability. Psychometric evaluation included Thurstone's test of ordinality and equidistance of response choices in 48 subjects as well as testing of reliability, validity, responsiveness and discriminative power of the form in crossectional studies of two samples of healthy persons and longitudinal studies of two samples of pain patients totalling 940 respondents. Quality ratings of translations were favorable, suggesting a high quality of both forward and backward translations. In the pilot study, the form was well understood and easily administered, suggesting high clarity and applicability. Thurstone's test revealed ordinality (in over 90% of the cases) and rough equidistance of response choices also as compared to the American original. On item and scale level, missing data were low and descriptive statistics indicated acceptable distribution characteristics. In all samples studied, discriminative item validity was high (over 90% scaling successes) and Cronbach's alpha reliabilities were above the 0.70 criterion with exception of one scale. Furthermore convergent validity, responsiveness to treatment and discriminative power in distinguishing between healthy and ill respondents was present. The preliminary results suggest that the SF-36 Health Survey in its German form may be a valuable tool in epidemiological and clinical studies. However further work as concerns responsiveness and population based norms is necessary.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
