The authors examined four factors: I) the effects of youngsters' vocational
and relationship experiences on their soft drug use, directly or by identi
ty formation, 2) the effects of adherence to non-traditional values of youn
gsters on their soft drug use, directly or by identity formation; 3) the ef
fects of parental divorce and parental affective involvement on youngsters'
soft drug use; and 4) the differences in these effects on boys and girls.
Data were used from the Dutch national panel study Utrecht study of Adolesc
ent Development (USAD), a study of developmental processes as they occur in
the life course of young people during the 1990s. Using linear structual r
elation (LISREL) model, we tested hypotheses on two waves of a sample of 19
66 respondents between 15 and 27years-of age. Vocational and relationship e
xperiences in adolescence were found to correlate with the use of soft drug
s. A low score on relational identity was found to be only a minor risk fac
tor for using soft drugs. Adherence to non-conventional norms and values in
crease the chance of using soft drugs.
