From field experiments to program implementation: Assessing the potential outcomes of an experimental intervention program for unemployed persons

This reprinted article originally appeared in American Journal of Community Psychology, 1991[Aug], Vol 19[4], 543-562. (The following abstract of the original article appeared in record 1992-14730-001.) Demonstrated a procedure suggested by H. S. Bloom (1984) to provide estimates for effects of an intervention on its actual participants compared to global effects on study participants in the intervention group, whether or not they showed up. Data on 1,087 Ss were collected in a field experiment that tested a preventive intervention for unemployed persons (R. D. Caplan et al, 1989). Effect size estimates were 2 to 3 times larger for participant group than for the entire experimental group on employment outcomes (e.g., earnings) and mental health (anxiety and depression). Compared to participants, nonparticipants achieved significantly higher levels of reemployment at posttests and did not differ significantly from participants on all other outcomes.
