“…The question of whether the experience of having a disabled or sick sibling influences children's adjustment and development is one of obvious practical and social importance. There is an extensive literature on the development and adjustment of the siblings of handicapped or sick children; for recent reviews of research on siblings of handicapped children see Brody and Stoneman (1983), Lobato (1983), McHale, Simeonsson and Sloan, (1984), Rodger (1985); for reviews on siblings of chronically sick children see Drotar and Crawford (1985) and McKeever (1983), Van Dongen-Melman and Sanders-Woudstra (1986); see also a special issue oi the Journal of Children in Contemporary Society, 1987. The literature on families with handicapped children documents the extent of emotional adjustment in the normal siblings and its relation to socioeconomic factors (Farber, 1959;Gath, 1974;Grossman, 1972), family structure variables such as gender, ordinal position and age gap (Breslau, Wietzman & Messenger, 1981;Cleveland & Miller, 1977;Faber, 1959;Farber & Ryckman, 1965;Gath, 1974;Grossman, 1972), parental attitudes (Caldwell & Guze, 1960;Grossman, 1972), quality of marital and parent-child relationships (Ferrari, 1984;McHale & Gamble, 1988) and extent of handicap (Breslau, Weitzman & Messenger, 1981;Grossman, 1972).…”
