Determinants of the risk and timing of alcohol and illicit drug use onset among natives and non-natives: similarities and differences in family attachment processes

This study examines data from Native Ontario reserve residents (Embree, 1993) and a sample from the Ontario Health Survey Supplement (1990-91) in order to compare and contrast the importance of family attributes such as parent-child attachment to Native and Non-native patterns of drug and alcohol use onset. Proportional Hazards modeling (Cox, 1972) was employed to identify factors associated with the risk and timing of onset of alcohol and illicit drugs for both cultural groups. For both Natives and Non-natives alike, and considering both drinking and drug use onset together, age cohort predominates as a risk factor, with youngest groups at greatest risk, and especially in the case of drug use other than alcohol. For the model of drug use timing, age of alcohol use onset is the second best predictor for Natives, although its effect is still apparent, albeit weaker, in the case of Non-natives. As for family characteristics, a number of factors emerge as determinants of risk and depend, in part, on the cultural group and the substance under consideration. Consistent with attachment theory's prediction about the universal applicability of the need for close parent-child relations (Bowlby, 1969), the findings for both Natives and Non-natives alike point to the salience of psychosocial attachment and other indicators of family functioning in affecting early onset drinking and drug use, behaviors well-recognized to lead to potentially adverse mental and physical health consequences as well as to negative social outcomes.
