in the past three months: Number of times used alcohol; The 6-point frequency response scale (0= "Never" to 5= "More than 20 times") was rescaled to a pseudo-continuous variable ranging from 0 to 20 using the mid-point of any range as the new value (e.g. 3-10 times was recoded as 6.5 times).

Participant Flow
this study included an examination of screening; thus, not all youth were part of the randomized controlled trial as they screened in at low risk. This is why there is a larger N for the overall sample. The 294 are the youth that screened in as at-risk who were then part of the RCT.
