We asked teachers to identify leaders and construct workgroups as 1 of 3
conditions in a randomized controlled trial testing the effectiveness of
a tobacco prevention program. Our expectation was that this condition
would not perform as well as student nominations of leaders and
construction of groups based on sociometric distance. At the 1 year
follow up it performed the best in 1 curriculum (the group based or
culturally tailored one compared to a standard social influences one)
compared to groups constructed randomly (with leaders of those groups
being those with highest in degree). The citations:

We collected data on teacher assignment in all 3 collections since the
study was blind to them.
