"Replacing" problem behavior: an analysis of tactical alternatives.

Johnston (2006) · The Behavior analyst 2006
★ The Verdict

Replacement behavior is a tool, not a requirement—skip it when simpler tactics will do.

✓ Read this if BCBAs who write behavior-reduction plans in any setting.
✗ Skip if RBTs looking for step-by-step skill-teach protocols.

01Research in Context

01

What this study did

The author looked at the common rule: 'Always teach a replacement behavior when you want to stop problem behavior.'

He checked the logic behind that rule. He used past studies and basic behavior principles, not new data.

02

What they found

The paper says the rule is more habit than science. Sometimes you need a replacement skill, sometimes you do not.

The author argues we should decide case-by-case instead of always adding a replacement response.

03

How this fits with other research

Meyer (1999) and Staats et al. (2000) show clear wins when a matched replacement skill was taught. Those papers are examples of the practice Johnston (2006) questions.

Potter et al. (2013) took a different path. They treated only mild precursor behaviors and severe problem behavior still dropped. That outcome supports the idea that full replacement is not always required.

Boyle et al. (2024) update the talk for multiply-controlled behavior. They still sequence treatments, but they do not claim every function needs its own topographically new response. The field is moving toward the lighter stance Johnston (2006) recommended.

04

Why it matters

Next time you write a plan, pause before you add 'teach replacement behavior' as a default line. Ask: Will removing the reinforcer be enough? Could I strengthen an existing skill instead of inventing a new one? This small shift can save teaching time and still give you a safe, durable result.

03Original abstract

A number of textbooks and professional volumes in applied behavior analysis suggest that interventions designed primarily to decrease a problem behavior should routinely be accompanied by efforts to increase the frequency of at least one appropriate behavior. Some sources describe the objective of this tactic as "replacing" the problem behavior. This paper considers rationales that might underlie this advice, as well as reasons why a general rule to this effect is inappropriate. This review reveals that although there may well be good reasons for considering this tactic, their rationales are often not well articulated and may even be unsound. It is also the case that there are good reasons why this tactic may not always be necessary, thus conflicting with an argument for a general rule.
