Summary
Brief summary
Parents can positively influence their children's alcohol use. One strategy they use is to
provide their children with alcohol, believing it is the best way to teach their children how
to drink responsibly. The impact of parental supply is not well understood and may be
unintentionally harmful. This study will research the consequences of parental supply within
the broader context of parent, child and peer relationships. It will help to determine how
parental supply influences the different patterns of adolescent alcohol consumption over
time, providing essential information to help parents prevent alcohol misuse in their
children. Parents can play a pivotal role in prevention of alcohol misuse, but at present we
don't know exactly how.
