This study introduces a multi-element paradigm for behavior support plans, combining proactive and non-aversive reactive strategies to safely manage challenging behaviors in children. The approach successfully reduced problem behavior frequency and severity without restrictive interventions.
Area of Science:
- Behavior Analysis
- Applied Behavior Analysis
- Child Psychology
Background:
- Ethical guidelines mandate the use of least aversive and restrictive behavior management strategies.
- Published behavior analysis studies often lack explicit detail on non-aversive reactive strategies for managing severe incidents.
- There is a need for clear paradigms integrating proactive and reactive approaches for behavior support.
Purpose of the Study:
- To introduce and discuss a multi-element paradigm for behavior support plans.
- To demonstrate the integration of ecological, positive programming, and focused-support proactive strategies.
- To highlight the role of non-aversive reactive strategies in rapidly and safely controlling behavioral incidents and reducing episodic severity.
Main Methods:
- Development of a multi-element paradigm incorporating proactive and reactive strategies.
- Analysis of three published studies implicitly using non-aversive reactive strategies (NARS).
- Application of the paradigm to support plans for three preschool children, utilizing comprehensive functional analysis and assessment (CFA) and multi-element behavior support (MEBS) plans.
Main Results:
- Proactive strategies successfully reduced the frequency of problem behavior occurrence.
- Reactive strategies effectively reduced episodic severity (ES), ensuring rapid and safe control during incidents.
- The multi-element paradigm led to successful outcomes without resorting to aversive or restrictive procedures.
Conclusions:
- The proposed multi-element paradigm offers an effective framework for behavior support.
- Integrating proactive and non-aversive reactive strategies is crucial for managing severe behaviors.
- Reducing episodic severity alongside behavioral frequency is a vital component of safe and ethical behavior management.
