Mitigating Unwanted Effects and Relapse

Key Takeaways

  • Interventions can produce unwanted effects, including emotional responding, aggression, avoidance, response bursts, and response covariation.
  • Risk mitigation includes least-restrictive selection, safety planning, monitoring, training, and prompt data review.
  • Relapse planning addresses resurgence, renewal, reinstatement, and loss of treatment effects across contexts.
  • Maintenance and generalization should be planned before fading supports, not added only after regression occurs.

Unwanted Effects and Relapse

A procedure can be evidence based and still require risk management. Extinction, punishment, schedule thinning, demand fading, and changes in reinforcement can evoke emotional behavior, bursts, avoidance, aggression, or collateral behavior change.

Mitigation begins before implementation. The BCBA should define risks, train implementers, obtain needed consent, monitor behavior and side effects, and set decision rules for pausing or modifying treatment.

Risk and Relapse Table

IssuePrevention or response
Extinction burstTeach and reinforce an alternative response before thinning.
Emotional respondingUse gradual changes, choice, and close monitoring.
ResurgenceKeep alternative reinforcement strong during transitions.
RenewalProgram across settings and people.
ReinstatementPlan for contact with old reinforcers or triggers.

Maintenance Planning

Maintenance means the behavior continues after intervention conditions change. Plan natural reinforcers, caregiver implementation, schedule thinning, self-management, and periodic probes. Do not remove supports faster than the data justify.

When relapse occurs, return to the data. Check whether the function changed, treatment integrity dropped, reinforcement schedules thinned too quickly, or the behavior entered a new context without programming.

Exam Tie-In

For exam scenarios, avoid answers that ignore side effects because the core procedure is evidence based. A stronger answer anticipates bursts, resurgence, renewal, and treatment-integrity drift, then uses data and client context to decide whether to maintain, thin, pause, or modify the plan.
