Wohlbefinden im Alter: Die Inhaltsvalidität der Ryff-Skala für BewohnerInnen von Pflegeheimen und betreuten Wohneinrichtungen

Background: Well-being is an important but rarely assessed outcome of care. The Ryff Scale of Psychological Well-Being measures this concept, but was not designed specifically for residents of assisted living facilities and nursing homes. Aim: To create a variant of this scale for the elderly in nursing homes and assisted living facilities in German speaking regions and to determine its content validity. Method: A study was conducted in Salzburg using the Delphi method, which consisted of two rounds containing 56 experts working in nursing homes and assisted living facilities. Suggestions for improvements were obtained by means of open-end questions. Acceptance of the items was rated on a 4-point Likert-scale. Items were accepted if a minimum of 80% of the experts agreed at least partially. During the qualitative analysis the statements of the experts were compared and summarised into codes and categories. Results: In the first round (response rate: 34.6%) 38 items out of 54 items were modified. The revised questionnaire received approval (≥ 80%) for all items in the second round (response rate: 64.7%). The experts criticised the phrasing of some items and also aspects of well-being, which in their opinion, are not relevant for the elderly in need of care anymore (e. g. performance of obligations). Conclusion: A modified scale was developed which was deemed appropriate by the experts for residents of nursing homes and assisted living facilities. This scale now requires psychometric testing. © 2016 Hogrefe.
