Although there were significant increases over the decade in the percentage of studies that checked adherence to treatment and used supervision to promote fidelity, the majority (55%) of the studies essentially ignored the issue of treatment fidelity. Furthermore, only one out of eight studies in the most recent period (1986-1988) combined the use of treatment manuals, supervision of treatment agents, and checking of adherence to protocol. Finally, attention given to the aforementioned aspects of fidelity did not differ significantly across journal domains. The overall implication of the review of existing practices is that investigators, reviewers, and journal editors need to give even greater consideration to the issues associated with fidelity. Specific recommendations for improving the promotion and verification of treatment fidelity in outcome studies were offered.
