BCBA exam practice question: Selecting and Implementing Interventions

Selecting and Implementing InterventionsDifficulty 3/5

After three weeks, a caregiver-implemented plan shows no improvement. Integrity data show the plan was implemented on 40% of opportunities. What is the appropriate next step?

  1. ARetrain and support the caregiver, then re-evaluate with integrity data
  2. BConclude the function was misidentified and repeat the functional analysis
  3. CDiscontinue services because three weeks without change indicates non-response
  4. DSelect a more intrusive intervention that is likely to overcome the resistance
Show answer and rationale

Correct: A. With low treatment integrity the data cannot evaluate the intervention. Improving implementation through training and support comes before changing the intervention or re-assessing function.

  • D — Escalating restrictiveness on uninterpretable data is both ineffective and ethically questionable.
  • B — Function cannot be ruled in or out when the procedure was rarely run.
  • C — Discontinuation is unwarranted and abandons the client.
