New from the NADD Press

NADD has published two important new books:

The Identification and Treatment of Trauma in Individuals with Developmental Disabilities by Sharon McGilvery

Sex Offending Behavior of Persons with an Intellectual Disability:  A Multi-Component Applied Behavior Analytic Approach by Dorothy M. Griffiths, Kendra Thomson, Stephanie Ioannou, Jordan Hoath and Robin J. Wilson

NADD Opposes Ruling on Electric Shock Treatment

We want to alert you to a recent decision made by a family court judge in Massachusetts to allow a school in Canton, MA to continue administering electric shocks to students with intellectual and developmental disabilities. This ruling goes against what we at NADD and many national disability organizations know to be true: the most effective treatment approaches for people with intellectual and developmental disabilities are not aversive but are driven by a person-centered, positive and strengths-based value set that ensures individual dignity.

NADD stands with The Association of University Centers on Disabilities AUCD and vehemently oppose this decision.

Following is an excerpt from the April 25, 2016 Proposed Rule Summary published in the Federal Register: The Food and Drug Administration (FDA) is proposing to ban electrical stimulation devices used to treat aggressive or self-injurious behavior. The FDA has determined that these devices present an unreasonable and substantial risk of illness or injury that cannot be corrected or eliminated by labeling. FDA is proposing to include in this ban both new devices and devices already in distribution and use.

We urge the FDA to move forward quickly and ban these harmful practices!
