The effects of methylphenidate on a functional analysis of disruptive behavior: a replication and extension

Area of Science:

• Behavioral Psychology
• Neurodevelopmental Disorders
• Pharmacological Interventions

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder.
• Individuals with ADHD may exhibit disruptive behaviors.
• Comorbid conditions like moderate mental retardation can influence behavioral presentation.

Purpose of the Study:

• To conduct a functional analysis of disruptive behavior in an 18-year-old male with ADHD and moderate mental retardation.
• To investigate the effect of methylphenidate on disruptive behaviors.
• To determine the reinforcing consequences of disruptive behavior under different medication conditions.

Main Methods:

• A functional analysis was employed to examine the participant's disruptive behavior.
• The analysis compared behavior when the participant was taking methylphenidate versus when not taking the medication.
• Data collection focused on identifying environmental factors and consequences maintaining the behavior.

Main Results:

• Disruptive behaviors were observed in the participant.
• The functional analysis indicated that access to attention served as a reinforcer for disruptive behaviors.
• This reinforcement by attention was contingent on the participant *not* taking methylphenidate.

Conclusions:

• Methylphenidate may alter the reinforcing properties of environmental stimuli for disruptive behavior.
• Functional analysis is a valuable tool for understanding behavior in individuals with comorbid ADHD and intellectual disability.
• Medication status can significantly impact the effectiveness of behavioral interventions.
