Document Summary

Glasgow et al. (1999) evaluating the public health impact of health promotion interventions: Efficacy-based research paradigm can be limiting and not always appropriate. Many interventions that prove efficacious in randomized trials are much less effective in the general population. Re-aim evaluation model emphasizes the reach and representativeness of both participants and settings, a(cid:374)d dis(cid:272)uss the (cid:373)odel"s i(cid:373)pli(cid:272)atio(cid:374)s for pu(cid:271)li(cid:272) health resear(cid:272)h. Representativeness of participants is an important issue for outcome research. Representativeness of settings (clinics, worksites, communities) for public health interventions is important. Many evaluations restrict selection of participating communities to those most motivated, and prepared for change results in expert/highly motivated research teams and setting which are unrepresentative. Low-intensity interventions that are less efficacious but that can be delivered to large numbers of people may have a more pervasive impact. Assessing representativeness is challenging requires demographic information, psychosocial/medical history, case mix information, ethical issues. The public health impact score is the best overall representation of quality.
