The Missouri Model: A Developmental Framework for Trauma Informed (MO Model) provides a map for organizations as they begin their journey toward trauma informed; presenting a developmental continuum beginning with trauma aware and ending with trauma informed. The MO Model is based on principles that were adapted from Fallot and Harris’s (2006) “Five Guiding Principles of Trauma Informed Care”. The definitions of the principles were reviewed and revised in 2022 by the MO Trauma Roundtable to include an understanding based on structural inequities.
