Intellectual and Developmental Disabilities Track

Mental Health Institute for Washington State Providers


Individuals with intellectual and developmental disabilities (IDD) show higher rates of mental health concerns than the general population. However, they have been historically underserved by behavioral health agencies. One reason they are commonly turned away from mental health services is because clinicians express a lack of knowledge and confidence to work with this population. Training activities offered in this track will focus on adaptation of commonly used therapeutic strategies to be utilized with clients with IDD and co-occurring mental health concerns. Training will focus on increasing skills and knowledge that providers can immediately use with their clients and share with their colleagues to better serve this population.



  • Increase knowledge and skills in treating co-occurring mental health conditions among individuals with IDD, to increase clinicians’ confidence in serving this population.
  • Apply adaptations of commonly used therapeutic approaches including Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT) for individuals with IDD to aid them in processing information and behavioral strategies.
  • Include voices of those with lived experience to improve care for historically underserved communities, highlighting the value and importance of serving this population.
