The Incredible Years DINA Small Group Therapy Curriculum is delivered in 2-hour weekly small group sessions (6 children/group with two facilitators) lasting 18-22 weeks.  It is recommended to offer the Incredible Years DINA Small Group Therapy Curriculum in conjunction with a weekly Incredible Years BASIC parent group to address how parents can help foster their child’s learning in the IYS DINA Small Group as their children are learning new skills.
