“…This research has suggested that even across different contexts and methodological approaches (e.g., community samples, population surveys), informal support—whether alone or in combination with professional services—consistently played a more central role in the care of older adults than professional services (e.g., Blieszner, Roberto, & Singh, 2001; Cohen, Miller, & Weinrobe, 2001; Davey et al, 2005; Penning, 2002). Even when the older adult had extensive care needs, informal supports were most often the main source of help, whereas professional service providers supplemented care as needed (Cohen et al, 2001; Davey et al, 2005; Nordberg et al, 2005; Penning, 2002).…”
