The impact of family members on aging persons’ technology use intentions by Freek Van Baelen, Melissa De Regge, Bart Larivière, Katrien Verleye, Kristof Eeckloo

“…RSA is often employed to understand complex, nonlinear interactions within a data set. It was investigated how the level of fit (when both the aging person and his or her family caregiver hold similar beliefs about the technological capabilities of the aging person) and the direction of misfit (whether the abilities of the aging person are greater or worse than the family caregiver thinks) shape the aging person's intention to use healthcare technologies. …”
