(ABA) Group Parent Training  

Effects of Group Parent Training & How to run a successful Group 


In this lecture, you will learn everything about Group Parent Training based on Applied Behavior Analysis (ABA). ABA is an evidence-based method, that has shown many positive outcomes over the last 60+ years. Studies have shown that parent training has a positive effect on many factors, such as the confidence of the parents, and the increased skills of their child. By using Group Parent Training, more opportunities will be presented for parents to learn, as also the interactions among parents add an increased value to their learning.  

Are you a parent, teacher, or professional, and want to learn more about Group Parent Training and perhaps, join a Group Parent Training I am hosting?  

Then this is an excellent lecture for you.  

Group Parent Training can be used for all kinds of situations. Parents who have children without a diagnosis (topics about developmental milestones can be addressed) and with a diagnosis (for example, Autism Spectrum Disorder, ADHD).  

Parents are usually the most consistent factors in a child’s life, being lifelong caretakers. The more knowledge and skills parents have, the easier it becomes for them to anticipate their child’s development and situations.

There is a lot of research that shows the tremendously positive effects of those positive peer relationships
