Problem: Analyze a behavior analytic case involving John, a 32-year-old man with moderate traumatic brain injury (TBI) and comorbid Major Depressive Disorder (MDD). The purpose of this assignment is to demonstrate your ability to interpret behavior analytic data, critically evaluate interventions, and apply ethical and interdisciplinary practices within a neurorehabilitation context.

Case Study: Traumatic Brain Injury (TBI) and Mental
Health - A Behavioral Analysis Perspective
Client Overview
Name: "John" (pseudonym)
Age: 32
Diagnosis: Moderate TBI, Major Depressive Disorder (MDD)
Date of Injury: June 2023
Referred by: Neuropsychologist for behavior assessment and support
Living Situation: Resides with partner; previously employed in construction
Current Supports: Neurorehabilitation team, psychiatrist, therapist, occupational therapist
Background and Referral Reason
John sustained a moderate TBI after a fall from a scaffold at work. Six months post-injury, he was referred to a behavior analyst due to:
- Increased agitation and verbal outbursts
- Withdrawal from previously enjoyed activities
- Inconsistent follow-through with rehabilitation tasks
- Poor emotional regulation and task avoidance
No history of behavioral issues or psychiatric conditions prior to the injury. The referral goal was to improve functional engagement and reduce maladaptive behaviors interfering with recovery.
Functional Behavior Assessment (FBA)
Target Behaviors Identified:
1. Task avoidance (e.g., refusing therapy, walking away from tasks)
2. Emotional outbursts (e.g., yelling, crying, pacing)
3. Low initiation (e.g., sitting idle, failing to start basic ADLs without prompts)
Assessment Methods:
- Direct observation in therapy and home settings
- Interviews with John and his partner
- Review of medical/rehab records
- ABC data collection across multiple sessions
Hypothesized Functions:
Behavior Antecedents Consequences Function
Task:
Avoidance
Presentation of cognitively
demanding tasks Tasks removed or delayed Escape
Outbursts Frustration from cognitive
difficulty, overstimulation Attention, task removal Escape + Attention
Low
Initiation
Unstructured environment,
lack of prompts
Tasks remain incomplete, partner

Escape (automatic,
skill deficit)
Behavioral Goals
1. Increase engagement in daily routines and therapy sessions
2. Reduce frequency and intensity of outbursts
3. Improve independent task initiation using environmental supports
Behavior Intervention Plan (BIP)
Strategies Used:
- Antecedent Interventions:
- Visual schedules and activity checklists
- Clear, concise task instructions
- Built-in breaks and structured environment
- Replacement Behaviors:
- Self-monitoring using a "frustration scale"
- Use of a "help" card and problem-solving prompts
- Behavioral momentum (start with easier tasks)
- Reinforcement Systems:
- Differential Reinforcement of Alternative Behavior (DRA): Earn tokens for completing tasks without escape behavior
- Preference assessments conducted weekly to identify effective reinforcers
- Partner-trained to deliver praise and immediate feedback
- Crisis Management:
- Calm-down protocol with a designated space
- Partner coached in de-escalation techniques
- Outbursts documented using severity ratings and debriefs
Behavior Analyst Role in Interdisciplinary Team
- Coordinated closely with the neuropsychologist and therapist to align behavior goals with cognitive therapy
- Trained family members and rehab staff on behavior strategies and data collection
- Advocated for consistency of supports across settings
- Provided regular data updates to inform medication reviews and therapy pacing
Ethical Considerations
- Ensured consent and assent throughout behavior intervention
- Used trauma-informed care principles (sensitivity to TBI-related changes, mood, and cognitive fatigue)
- Monitored for signs of psychiatric instability and referred when needed
- Reinforced autonomy and client dignity at all stages

Assignment Components:
1. Functional Behavior Assessment (FBA) Interpretation
- Identify and operationally define the key target behaviors
- Discuss the hypothesized functions using ABC data and assessment findings
- Interpret the role of antecedents and consequences in maintaining behavior
2. Behavior Plan Evaluation
- Describe the BIP strategies including antecedent interventions, replacement behaviors, and reinforcement systems
- Evaluate the alignment between behavioral function and intervention
- Discuss the use of data collection and feedback loops
3. Recommendations:
- Suggest at least two evidence-based modifications or additions to the current BIP
- Justify your recommendations using behavioral principles and literature
4. Interdisciplinary Collaboration:
- Explain how the behavior analyst can effectively collaborate with medical, therapeutic, and family stakeholders
- Discuss the importance of shared goals and consistency across environments
5. Ethical Considerations:
- Identify ethical concerns related to trauma-informed care, consent/assent, autonomy, and professional scope
- Reference relevant BACB Ethics Code elements where applicable
