UMARU IMPACT Study data
A data.frame with
\(575\) observations (rows)
and \(9\) variables (columns).
A subset of data from the University of Massachusets Aids Research Unit (UMARU) IMPACT study.
This came from two concurrent randomized trials of residential treatement for durg abuse, in order to compare planned durations of admission.
Site A randomized 444 participants to compare 3 and 6 month stays in a therapeutic community. They were trained to recognize triggers for relapse and taught skills to cope without using drugs.
Site B randomized 184 participants to receive either a 6 or 12 month stay in a highly structured communal therapeutic community.
This is a subset of the original dataset.
