Applied behavior analysis: its impact on the treatment of mentally retarded emotionally disturbed people.

Koegel et al. (1992) traced how early lab work in ABA moved into real-world care.

They looked at people who had both intellectual disability and serious emotional problems.

The paper is a story-style review, not a new experiment.

The authors showed that first-generation ABA tactics became self-help and mental-health tools.

No new numbers were given; the piece is a historical map.

Fantino (1981) told the same spread story a decade earlier, but for all fields, not just ID.

Rasing et al. (1992) extends the idea into classrooms the very same year.

Gitimoghaddam et al. (2022) later scooped 770 studies and found big gaps—only 4% had control groups—showing the field still leans on the early faith L et al. described.

If you serve adults or youth with dual diagnosis, this paper reminds you that today’s tools stand on 1990s shoulders. Use it to explain to teams why we keep data, break skills down, and pair respect with science.
