Several clinic-based programs have been evaluated with experimental designs and three (out of five) of them showed some positive impacts on reproductive health outcomes (Danielson et al., 1990; DeLameter et al., 2000; Orr et al., 1996). Those programs that showed positive impacts included one-on-one counseling and delivered a clear message about appropriate reproductive health behaviors (Kirby, 2001). School-based health centers and condom-availability programs have not had experimental evaluations, and thus cannot be included in the “what works” section of our final table. Available studies suggest that these programs show mixed associations with reproductive health outcomes.
