This study is based on a subsample of 15- and 16-year-old school students f
rom the UK, part of the European School Project on Alcohol and Other Drugs
(ESPAD). information was available on truancy rates, perceived school perfo
rmance, family structure, lifestyle, and usage of alcohol, cigarettes and i
llicit drugs in 6409 teenagers. Living in a single-parent family, lack of c
onstructive hobbies, presence of psychiatric symptoms, and an aggressive ou
tgoing delinquent lifestyle bore the strongest associations to truancy and
to perceived school performance. There were also strong relationships betwe
en both these last two variables and use of alcohol, cigarettes, and illici
t drugs. However, the effects of alcohol, cigarettes, and illicit drugs wer
e largely accounted for by other variables. Having at least one parent who
both supported the respondent and who exercised some control was predictive
of better perceived school performance.
