The dynamics of mental health of the population of the Altai Territory evaluated within a ten-year study (1991-2000) revealed pronounced negative processes with the most essential ones being in the children and teenagers category. The complicated social-and-economic transformations conducted in Russian society during the last decade of the past century, which entailed the misadjusted response in a majority of population, exerted an unfavorable influence on the mental health condition. The authors suggested a system of measures and arrangements targeted at neutralizing the detected negative trends in the population mental health; the above system can be successfully used in any country's region.
