Improvement of retardates' mealtime behaviors by timeout procedures using multiple baseline techniques

Area of Science:

• Behavioral Psychology
• Developmental Disabilities
• Applied Behavior Analysis

Background:

• Individuals with intellectual disabilities often exhibit challenging mealtime behaviors.
• Effective interventions are crucial for improving dining experiences and promoting independence.

Purpose of the Study:

• To evaluate the efficacy of contingent timeout procedures in reducing undesirable mealtime behaviors.
• To observe the emergence of appropriate mealtime behaviors following intervention.

Main Methods:

• A multiple baseline design was employed across different undesirable behaviors.
• Contingent timeout procedures, including removal from the dining area or meal tray, were systematically applied.
• Behaviors such as stealing, inappropriate finger use, messy utensil use, and pigging were targeted.

Main Results:

• Contingent timeout led to significant reductions in targeted undesirable mealtime behaviors.
• The reduction of one behavior sometimes coincided with an increase in another, suggesting behavioral contrast.
• Appropriate mealtime behaviors, such as neat utensil use, emerged as undesirable behaviors decreased.
• Subject weights remained stable throughout the study.

Conclusions:

• Contingent timeout is an effective strategy for modifying mealtime behaviors in individuals with intellectual disabilities.
• Behavioral interventions can foster the development of adaptive skills and improve dining environments.
• Further research can explore long-term effects and individualization of timeout procedures.
