A decade of research on religion and counseling, consisting of 148 empirical articles, was reviewed. Methodological sophistication, poor a decade ago, has approached current secular standards, except in outcome research. Religious people cannot be assumed to be mentally unhealthy. Nonreligious and religious counselors share most counseling-relevant values but differ in the value they place on religion. Those religious differences affect clinical judgment and behavior, especially with religious clients. Religious interventions have been techniques imported from formal religious traditions and used as adjuncts to counseling or traditional theories of counseling adapted to religious clients. The authors suggest a research agenda and speculate about future mental health practices.
