A study published in The Journal of Child Psychology and Psychiatry found that conduct problems occurring among participating kindergarteners were associated with long-term costs that researchers were able to quantify through economic analysis. These costs were borne by the individual participants as well as by society at large, and point to the long-term costs of serious behavioral challenges in early childhood programs (and relatedly, the preventative power of intervening early).
Researchers examined data from over 1,300 kindergartners from various states in the late 1980s and early 1990s; these children were participating in two longitudinal child development studies at the time. Conduct problems were measured by teacher and parent reports (according to several established screening tools) and children were then tracked over time to assess later behaviors incurring personal – and societal – costs. These long-term costs were measured through review of records (e.g., administrative court data) and self-reported data from the study participants themselves. Long-term costs included those related to adolescent crime (costs to self and to victims); medical-related costs; and other government-related costs (e.g., use of housing or food assistance). The study found that an increase in kindergarten conduct problems was associated with clear increased costs related to crime – both as adolescents and adults; medical services; and total costs to society - a measure that included criminal legal costs, offender productivity costs, victim costs, and costs from government service and medical service use. The study authors note that their research “provides evidence of the long-term costs associated with early-starting conduct problems, which is important information that can be used by policymakers to support research and programs investing in a strong start for children.”
