ABSTRACT
It is recognized that high-risk behaviors are significantly interrelated, especially among youths (Penkower, Dew, Kingsley, Becker, Satz, Schaerf and Sheridan 1991). For this reason it is suggested that prevention programmes be developed that target the underlying determinants of several theoretically and empirically related problem behaviors (Botvin 1982; Swisher 1979). These observations suggest that generic interventions addressing more than one behavior or predisposing factors are preferable to approaches that target only one risk factor, or that employ only one intervention method (Harvey 1997).
