Assertive Community Treatment for People With Mild Intellectual Disability or Borderline Intellectual Functioning and Mental Health Problems or Challenging Behavior: State of the Art and Implementation in the Netherlands

Individuals with mild intellectual disabilities (MID) or borderline intellectual functioning (BIF) and mental health problems or challenging behavior are difficult to reach by mainstream healthcare facilities and support organizations and frequently avoid the care they need. To improve the care for this client group in the Netherlands, the (Flexible) Assertive Community Treatment (ACT) model—originally developed for people with severe mental illness—was adapted and implemented by five organizations specialized in the care for people with MID/BIF and mental health problems or challenging behavior. After an introduction of the original ACT model and a description of the international state of the art of ACT for people with (M)ID/BIF, this paper describes the (Flexible) ACT‐MID/BIF model as developed and implemented in the Netherlands. Professionals' and clients' experiences with this new type of care are reported as well. Implications for clinical practice, policy and research are discussed.
