Integrated Behavioural Development (IBD) is an approach that combines the principles of Applied Behaviour Analysis (ABA) with the elements of Social and Emotional Learning (SEL) to foster comprehensive growth and development in individuals. It recognizes the importance of addressing both observable behaviours, which are a key focus of ABA, and the social and emotional aspects of well-being emphasized by SEL. IBD seeks to create a balanced and inclusive framework that supports individuals in not only developing appropriate behaviours but also enhancing their social skills, emotional regulation, and overall mental health. This holistic approach is designed to promote a more well-rounded and healthy development in individuals, whether they are children, students, or individuals with special needs.
