Presented in five parts on research, services, training, drug abuse, and alcohol abuse are 31 reports of mental health studies and programs supported by the U.S. and other countries. Explained in the introduction are reasons the National Institute of Mental Health (NIMH) has supported international collaboration. The following are among subjects of 19 research reports given in Part 1: NIMH assessment of schizophrenia research in the USRR (1972); international pilot study of schizophrenia; six-country study of effects of modernization; Hawaiian psychopathology and normality; megavitamin, tranquilizer and drug studies for the aged in Canada; English autistic children; genetic/environmental influences on criminality in Denmark; psychoses in Croatia (Yugoslavia); suicide (Scandinavia, Los Angeles, and Vienna); Swedish laboratory methods; child rearing in the U.S. and Japan; and Micronesian thinking patterns. Focused on among four reports on services (Part 2) are an overview, NIMH observation of USSR services (1967), and family role in children's hospital care (U.S.). Training in Part 3 is examined in three reports on foreign researchers in U.S. laboratories, foreign work-study assignments, and anthropology fellowships. Offered in Part 4 are four drug abuse reports on international cannabis research, international programs, narcotic addiction treatment in Iran, and a NATO drug rehabilitation project. The one report in Part 5 covers international studies on alcohol abuse and alcoholism. Directions for future collaboration are examined. (MC)
