“…Research in the 1960s and 1970s identified that abuse of alcohol does occur in this group (Rosin and Glatt, 1971), though it is less common than in younger adults (Warheit and Auth, 1984). Research in the United States and Britain has shown prevalence rates of 413% in community surveys (Meyers et al, 1982;Calahan et al, 1969;Barnes, 1979;Bridgewater et al, 1987), the rate in institutions being much higher, perhaps up to 60% (Caracci and Millar, 1991). Alcohol has been implicated in up to 50% of medical and psychiatric hospital admissions (McCusker et al, 1971;Simon et al, 1968;Gaitz and Bayer, 1971).…”
