EVALUATING RESPONSE MECHANISMS IN A LIFE-SPACE MOBILITY INSTRUMENT WITH A ‘STEM AND LEAF’ FORMAT
J Frailty Aging 2013;2(2):84-89
Background: Life-space mobility scales in the very old (aged 80+) have begun to be used as a way of gauging their enacted mobility. Objectives: To investigate if there is evidence that response patterns are being affected by the “stem and leaf” format of a life-space mobility instrument. Methods: Descriptive statistics, readability ease scoring, ten ordinary least square regression on a total of 698 females and 376 males from Wave-7 collected during 2010-2011 for the Hispanic Established Population for the Epidemiological Study of the Elderly. Results: Response patterns seem to indicate that the stem and leaf format of the life-space mobility instrument is not creating item non-response, illogical responses, or ‘no’ responses. Conclusions: Because self-reports are so frequently used, more research is needed to ascertain how instrument formats affect response mechanisms.
