[Family caregivers and health promotion. Pilot study to validate a German assessment to survey resources and risks of elderly family caregivers (ARR)].

The ARR is a German assessment instrument to survey physical and psychological resources and risks of elderly family caregivers (50+). Factor structure, reliability, and validity were investigated using a sample of 202 caregivers from a national health insurance company. The factorial validity was confirmed for the physical profile (PHP) and the psychological profile (PSP). Reliability is good (PHP: Cronbach's α=0.73; PSP: Cronbach's α=0.71) for the shortness of the profiles. The correlation with self-efficacy constitutes an indicator for construct validity. The psychometric qualities allow the conclusion that the ARR is a reliable and valid instrument which is of interest for family caregivers. Nevertheless, further testing of validity is required.
