KOHLBOECK, Gabriele; QUADFLIEG, Norbert  and  FICHTER, Manfred M.. Acting out and self-harm in children, adolescents and young adults and mental illness 18 years later: The Longitudinal Upper Bavarian Community Study. Eur. J. Psychiat. [online]. 2011, vol.25, n.1, pp.32-40. ISSN 0213-6163.

Background and Objectives: To assess the predictive impact of childhood/adolescent/young adult acting out and self-harm in a community sample of 224 participants on mental illness 18 years later. Methods: Assessments focusseded on a baseline in 1980-84 and the results at a 18-year follow-up from 2001-2004. Self-rating scales as well as expert-rating interviews yielded data on acting out, self-harm, psychiatric diagnoses and psycho-social outcome. Results: The participation rate at 18-year follow-up was 82% of those of the baseline sample. Regression analyses showed these results: Acting out and self-harm predicted later mood disorders. Self-harm predicted later psychiatric treatment in the year preceding 18-year follow-up, and impairment in social functioning. Conclusions: Our data contribute to a better and broader understanding of the impact of acting out and self-harm in childhood/adolescence/young adulthood on mental illness and its consequences in adult age and underscore the need for early and intensive intervention at many levels to prevent the accumulation of psychological problems in this age.
