Behavioral treatment of self-stimulation in the developmentally disabled. A methodological review.

Schrader et al. (1983) · Behavior modification 1983
★ The Verdict

Most early stereotypy studies were methodally shaky—use their own checklist so your next intervention holds up to modern scrutiny.

✓ Read this if BCBAs writing grants, theses, or treatment protocols for automatically maintained stereotypy.
✗ Skip if RBTs looking for a quick 5-minute procedure card.

01Research in Context

01

What this study did

The authors read 38 early studies that tried to stop hand-flapping, rocking, and other self-stim in kids with developmental delays.

They graded each paper for scientific quality. They asked: Did the study have clear rules, good data, and proof the treatment really worked?

02

What they found

Most papers said the treatment worked, but the proof was weak. Many studies used only one kid, had no control, or stopped measuring too soon.

The review gives a one-page checklist you can use today to spot these same flaws in new studies.

03

How this fits with other research

Smith et al. (2014) is the direct sequel. That 2014 editorial opens a full journal issue packed with newer, better-designed stereotypy studies.

Llinas et al. (2022) shows the upgrade: they ran an alternating-treatments design with three NCR schedules and clear effect sizes—exactly the rigor C et al. wanted.

Phillips et al. (2017) adds 27 real cases and finds NCR alone helps socially maintained behavior, but automatic stereotypy needs extra parts. This large set answers the old worry about tiny samples.

Scahill et al. (2015) extends the lens to measurement. They pick only five tools trial-ready for autism RRBs, echoing the 1983 call for tighter methods.

04

Why it matters

Before you write a treatment plan or start a thesis, open the 1983 checklist. It still catches rookie mistakes like missing baselines or fuzzy definitions. Pair it with the 2014 special issue and 2022 NCR data to build a study that actually convinces reviewers—and helps kids stop stereotypy faster.

03Original abstract

Thirty-eight studies on the behavioral treatment of self-stimulation in the developmentally disabled were reviewed and evaluated across 17 methodological variables. Factors including the techniques employed, measurement of collateral behaviors, and generalization of treatment gains were examined for each study, and a summary of clinical knowledge to data is presented. Results indicated that while behavioral treatment of stereotypy appears to be an effective treatment modality, methodological shortcomings in the majority of studies prevents definitive conclusions. Guides for improving research in this area are provided.
