Zusammenfassung

Im Rahmen eines Vergleiches telefonischer und postalischer Befragungsmethoden wurde der SF-8 als Instrument zur Messung der gesundheitsbezogenen Lebensqualität bei Erwachsenen eingesetzt. Die aus 1690 Personen im Alter zwischen 25 und 66 Jahren bestehende Stichprobe wurde randomisiert zur Hälfte telefonisch und zur anderen Hälfte postalisch befragt. Verglichen wurden die je nach Darbietungsmodus erzielten Ausfüllraten, zentralen Tendenzen, Streuungen, Decken- und Bodeneffekte in den Messwerten des SF-8 sowie die Korrelationen zwischen den Items. Die Bedeutung des Alters und des Geschlechtes für die Unterschiede wurde untersucht. Die Resultate des Methodenvergleiches zeigen je nach Darbietungsmodus und erfragtem Gesundheitsaspekt keine oder geringe statistisch signifikante Unterschiede in der Beantwortung des SF-8. Als Fazit sollte in weiteren Untersuchungen die genaue Natur der Abweichungen untersucht und Korrekturfaktoren ermittelt werden.

Abstract

Within a comprehensive comparison of telephone and postal survey methods the SF-8 was applied to assess adult’s health-related quality of life. The 1690 subjects were randomly assigned to a telephone survey and a postal survey. Comparisons across the different modes of administration addressed the response rates, central tendency, deviation, ceiling and floor effects observed in the SF-8 scores as well as the inter-item correlation. The importance of age and gender as moderating factors was investigated. Results indicate no or small statistically significant differences in the responses to the SF-8 depending on the actual mode of administration and the health aspect questioned. It was concluded that further investigations should focus on the exact nature of these deviations and try to generate correction factors.

Notes

  1. Da in die oben genannten Responseraten beider Stichproben auch diejenigen Haushalte einbezogen wurden, in denen nur eine Befragung, also eine Eltern- oder eine Kinderbefragung, durchgeführt werden konnte, weicht die Zahl der zur Verfügung stehenden Elternbefragungen von der Summe der insgesamt befragten Haushalte ab.
