Longitudinal Evaluation of the Neurosequential Model of Therapeutics with Adoptive Families in Tennessee.

PURPOSE

This study evaluated effectiveness of the Neurosequential Model of Therapeutics (NMT) with adoptive families who received post adoption services in Tennessee.

METHODS

Researchers obtained a sample of 552 families who received post adoption services in the U.S. state of Tennessee. Most families (77%) had adopted children through public child welfare services. A quasi-experimental design examined wellbeing outcomes for an NMT group ( = 319) versus a services-as-usual (SAU) group ( = 233) in intent-to-treat analyses. Then, the SAU group was contrasted to an NMT subgroup that had high adherence to the NMT model ( = 109) in an analysis of treatment-on-the-treated.

RESULTS

Intent-to-treat models indicated no differences on outcomes between the NMT and SAU groups. However, the results of treatment-on-the-treated analyses showed slightly greater reduction on the Behavior Problems Index over time for the NMT with high adherence group as compared to SAU.

DISCUSSION AND CONCLUSION

Adoptive families may face challenges that could be addressed through developmentally sensitive, trauma-informed services, such as NMT. The results of this study suggest that the NMT might benefit adoptive families if greater attention is paid to implementation adherence, or fidelity.
