Neuroleptics and psychosocial treatments: a discussion

Designs of clinical trials that will permit evaluation of independent, additive, and interactive effects of drugs and psychosocial treatments are described.

Data from the articles in this issue are drawn upon the support the contention that the current state of knowledge in both drug and psychosocial treatment research makes such studies ethically and scientifically possible and highly desirable clinically.
