Patientenzufriedenheit in der stationären Rehabilitation: Psychometrische Reanalyse des ZUF-8 auf der Basis multizentrischer Stichproben verschiedener Indikation: Patients’ satisfaction in inpatient rehabilitation. Psychometrical evaluation of the ZUF-8 based on a multicenter sample of different indications
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.

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.
