Trial Profile of practices and cohort sample.

<p>* Young people were ineligible if they were: unable to speak English; physically or mentally unwell; or, under 18 years old, judged by clinician to be incompetent to make an informed decision for participation in minimal risk research and unable or unwilling to obtain parental consent. † Never had contact (wrong phone number, too many attempted phone calls, or responded more than three weeks post consultation and were therefore too delayed to participate). ‡ A small number of young people completed the baseline survey and 12 month follow-up CATI but did not complete the three month CATI because they were too busy, away or not contactable during this time. § Denominator used to calculate the percentage is the total number of young people who consented and completed exit interview. ¶ One practice had no young people complete the 12-month CATI.</p

Clinicians detection of risk-taking behaviours of the young person at the consultation measured at the “Exit interview” in the cohort sample of young people (N = 901).
