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.
Selecting and Implementing InterventionsDifficulty 2/5

Which strategy best promotes generalization of a newly acquired greeting response?

  1. AIncrease reinforcement magnitude in the teaching setting to strengthen the response
  2. BTrain sufficient exemplars across people and settings and recruit natural reinforcement
  3. CRun more massed trials with the same therapist until responding is fluent
  4. DDelay generalization work until mastery in the teaching setting is documented
Show answer and rationale

Correct: B. Programming common stimuli, training multiple exemplars and recruiting natural communities of reinforcement are established generalization tactics. Concentrating practice in one context narrows stimulus control.

  • A — Stronger reinforcement in one setting does not transfer stimulus control.
  • C — More of the same context strengthens the narrow control.
  • D — Generalization is designed into teaching, not appended afterwards.
