“…* In 1911 a commission of the American Academy of Medicine and the American Medical Association was concerned with the presumed modelling impact of newspaper reports on suicide (Hemenway, 1911). In more recent studies there are repeated references to epidemics of suicides or the imitation of suicidal acts among schoolchildren (Ringel et al 1955;Harbauer, 1978), among adolescents (Robbins & Conroy, 1983;Rubinstein, 1983;Doan, 1984;Fox et al 1984;Taylor, 1984), in institutions (Crawford & Willis, 1966;Matthews, 1968;Olin, 1980;Rada & James, 1982;Walsh & Rosen, 1985) or in particular ethnic populations (Ward & Fox, 1977;Rubinstein, 1983). However, all these previous observations, as well as the results of studies lacking a satisfactorily elaborated theoretical basis, are in themselves inadequate for the demonstration of a causal relationship between model behaviour and imitation.…”
