From adolescence to adulthood: Development of psychopathology in kibbutz and town subjects

The unique contribution of the National Institute of Mental Health—Israeli longitudinal high-risk study is the comparison of the development of children at high risk for schizophrenia from two divergent socialization environments: the Israeli urban nuclear family and the collective education in the kibbutz. The study began with 100 preadolescent children who were followed up into adolescence, with outcomes measured in their 20s and 30s. No difference in the prevalence of schizophrenia was found at the last follow-up phase, with subjects at an average age of 32, but a higher incidence of major depression was found in the kibbutz than in the urban high-risk group. The data suggest adolescence as the period in which the differential effects of environment began to appear. Environmental factors, related to the social structure of the kibbutz, which may have led to this outcome, are discussed.Received Ph.D. in psychology from the Hebrew University, Jerusalem.
