Abstract: Objectives: In the last few years the questionnaire ZUF-8 received
increasing approval as screening-test for the measurement of
patients' satisfaction. Main intention of this article is the
psychometrical evaluation by means of a large sample and the identification of
relevant cut-offs. Methods: A sample of more than 50000 patients, which was
collected within a routine monitoring of eleven clinics for rehabilitation and
a smaller sample deriving from a program evaluation study, could be evaluated.
The questionnaire was analysed based on scale, item and factor analysis. For
validation, demographic variables, quality-ratings and standardized assessment
methods, which are often used in designs of rehabilitation research (e.g.
SCL-90-R, IIP-D, FLZ, SF-36), were available. Finally ROC analyses were
performed with two different criteria to recognize specificity and sensitivity
of possible cut-offs. Results: The ZUF-8 could be validated as one-dimensional
and reliable scale (Cronbach's α=0.90). The questionnaire has
sufficient validity as regards to both detailed quality measurement of the
service and treatments' results. The ROC analysis investigated
critical cut-offs for both criteria in each case for all medical fields
involved. Moreover the relationship between doctor/therapist and patient could
be identified as basic element of patient's satisfaction. Conclusions: The psychometric properties of the ZUF-8 could be replicated
convincingly and could be extended by reason of relevant cut-offs'
ascertainment. The ZUF-8 is an extremely economic screening questionnaire for
patients' appraisal of actual state of satisfaction, which is of
high importance regarding to competition and quality.
