“…Biographical data were to a large extent ignored. Data that allegedly could differentiate between youthful offenders are, e.g., the socio-economic background (Cloward and Ohlin, 1960;Cohen, 1955;Short, 1968), the type of offense (Wattenberg and Balistrieri, 1952;Kraus, 1974), the presence or absence of the father (Oshman and Manosevitz, 1976;Virkkunen, 1976), the father's disciplinary role (Fodor, 1973;Robins, 1966) and the delinquent's intellectual abilities (Tennent and Gath, 1975).
