Naturalistic treatment of an autistic child.

Nordquist et al. (1973) · Journal of applied behavior analysis 1973
★ The Verdict

Parents can run a solid home ABA program if you first train them in clinic and keep their rewards strong.

✓ Read this if BCBAs starting home-based programs for young autistic clients.
✗ Skip if Clinicians looking only for large-group RCT data.

01Research in Context

01

What this study did

The team worked with one autistic child and his parents. First they taught the parents in a clinic. Then the parents ran the program at home.

They used simple rewards and prompts. The goals were fewer tantrums, more listening, and new imitation skills.

02

What they found

Rituals and crying dropped. Compliance and imitation grew. The child kept the gains while parents kept the plan.

The study showed parents can be the main therapists if you give them clear steps and strong reinforcers.

03

How this fits with other research

Lovaas et al. (1973) ran the same idea with twenty kids. Gains lasted only when parents kept using the tactics. The single-child result lines up with the larger group.

Breider et al. (2024) later tested parent training in a full RCT. Face-to-face coaching beat a wait-list, giving stronger proof than the 1973 case.

Singh et al. (1982) asked parents how they felt. Most liked the cotherapist role, yet half quit the methods later. This warns us to build follow-up support from day one.

04

Why it matters

You already know parent training works. This 1973 paper is the seed that grew into today’s programs. Use it when you need a quick story: teach in clinic, practice at home, keep reinforcers powerful, and check back often so parents don’t drift.

03Original abstract

The present research experimentally evaluated a "naturalistic" treatment program for an autistic child administered by the parents over a 2-yr period. Operant reinforcement techniques previously developed and tested in laboratory settings were initially assessed in a clinic and eventually in the family's home. Experimental manipulations were performed in both settings on rituals, crying and whining, compliance, non-verbal imitation, and verbal imitation. The results clearly indicated that parents can effectively treat autistic behaviors provided that they receive adequate training and supervision in operant reinforcement therapy, and provided that sufficiently potent reinforcers are available to maintain behavior.
