Toward an explicit technology of ecological validity

Fahmie et al. (2023) read every JABA article from 2019 to 2021. They looked for the words ecological validity. They wanted to see how often authors said their study looked like the real world.

The team then wrote a one-page checklist. It lists 12 places to add real-world detail when you plan a study. Things like: use the same room, toys, and people the child sees every day.

Most JABA papers never mention ecological validity. When they do, they rarely say how they achieved it.

The new checklist gives clear yes/no items. A reader can open any paper and quickly see if the study mirrors everyday life.

Wallander et al. (1983) warned that JABA authors skip key details about how they picked subjects. Fahmie’s 2023 paper shows the same gap now applies to ecological detail. Both papers end with the same fix: add a short checklist to every report.

Bergmann et al. (2023) audited JABA the same year. They found authors rarely explain procedural fidelity. Like Fahmie, they offered a checklist. Together the two papers give BCBAs twin tools: one for doing the steps right, one for keeping the steps real.

Stephens et al. (2025) found social-validity data are also scarce in functional analyses. Fahmie’s ecological checklist can piggy-back on that call: add two quick boxes for parent and teacher ratings and you cover both social and ecological validity in one go.

If your study looks nothing like the child’s classroom, the beautiful behavior change may never leave the lab. Use the checklist while you write the method section. Check off items such as ‘same lighting,’ ‘peer partners present,’ ‘materials from the classroom shelf.’ In 5 minutes you raise the odds that next month the teacher will actually run your intervention.
