Seven findings, statistically significant, are summarized in order to substantiate with empirical data the need for introducing the "causal" approach to preventive mental health as an integrated part of the curriculum, beginning at the kindergarten level and continuing through senior high school level. Sources of data are cited for findings which deal with the application of understandings, development of an analytical approach, authoritarianism and responsibility assumption, punitiveness and misbehavior, anxiety and insecurity, and peer acceptance and self concept. To endorse this approach, the Committee on Preventive Psychiatry of the Group for the Advancement of Psychiatry has listed six points advocating the use of the causal approach and materials, as developed by Dr. Ralph H. Ojemann and his associates. (BL)
