There is a wealth of research studies that demonstrate the effectiveness of Behaviour Analysis in helping children with autism learn to effectively communicate, acquire academic and adaptive skills, and engage in meaningful social interactions with family and peers. Behaviour Analysis also can be effective in replacing problem behaviours (e.g., tantrums, self-injury) with behaviours that help children access the reinforcers they want in more appropriate ways. Child Autism UK has collected a bibliography of studies demonstrating the positive effects of ABA-based therapies for children with autism.

Research also supports the effectiveness of behaviour therapy with those with mild to moderate depression, anxiety, phobias, sleep problems, and in those with poor problem-solving and self-management skills. There are a number of scientific journals devoted to publishing this research.
