Therapy outcome research. Threats to treatment integrity.
Build integrity checks into your program before the first session starts.
01Research in Context
What this study did
The author listed every way a therapy study can quietly fall apart.
He called these cracks “treatment integrity threats.”
The paper is a map, not an experiment.
What they found
Therapists can drift from the script. Clients can skip steps.
Either slip ruins the data.
The fix is to write safeguards into the study before day one.
How this fits with other research
Morris et al. (2022) asked 232 BCBAs what really goes wrong. Their survey shows data-collection errors are the modern form of the 1984 threats.
Kodak et al. (2021) built a 9-step tutorial for comparing teaching methods. Each step hides a mini version of the 1984 checks.
Ingham (1983) had already warned that token studies flop when staff drift. The 1984 paper widened that warning to all behavior therapy.
Why it matters
If you run sessions, collect data, or supervise RBTs, this paper is your cheat sheet for spotting invisible cracks. Add a quick integrity checklist to your next program. One minute of review can save weeks of useless data.

03Original abstract
Integrity of treatment refers to the extent to which the intervention conditions in an experiment are implemented as intended. Therapist and subject integrity of treatment violations can influence the results of therapy outcome research. This article identifies potential integrity of treatment transgressions in behaviorally oriented research and offers guidelines to minimize potential integrity of treatment violations.
