Understanding the Behavior Analyst Role

Before diving into specific interview questions, it's essential to understand what employers are looking for in a behavior analyst. These professionals work with individuals across various settings—from schools and clinics to homes and community centers—implementing evidence-based interventions to improve socially significant behaviors.

Key responsibilities typically include:

• Conducting functional behavior assessments
• Developing and implementing behavior intervention plans
• Collecting and analyzing data
• Training staff and caregivers
• Ensuring ethical compliance with BACB guidelines
• Collaborating with multidisciplinary teams

Essential Technical Questions and Expert Answers

1. "Explain the four functions of behavior according to ABA principles."

Expert Answer:
"The four functions of behavior, as identified in Applied Behavior Analysis, are:

Attention-seeking: The individual engages in behavior to gain social attention from others, whether positive or negative.

Escape/Avoidance: The behavior serves to remove or avoid an unpleasant stimulus, task, or situation.

Access to tangibles: The individual seeks to obtain preferred items, activities, or sensory experiences.

Automatic reinforcement: The behavior is maintained by internal consequences, such as sensory stimulation or pain reduction.

Understanding these functions is crucial because effective interventions must address the underlying reason why a behavior occurs. For example, if a child engages in disruptive behavior to escape academic tasks, simply providing attention for the behavior would likely increase rather than decrease its frequency."

2. "Describe the difference between positive and negative reinforcement."

Expert Answer:
"This is a common area of confusion, but the distinction is fundamental to ABA practice:

Positive reinforcement involves adding something desirable after a behavior to increase its likelihood of occurring again. For example, giving praise after a student completes their homework.

Negative reinforcement involves removing something unpleasant after a behavior to increase its likelihood. For example, turning off loud music when a child sits quietly.

Both types of reinforcement increase behavior—the key difference is whether we're adding something good (positive) or removing something unpleasant (negative). I often use the analogy of a thermostat: turning up the heat (positive) versus turning off the air conditioning (negative) both achieve the goal of warming the room."

3. "How would you conduct a functional behavior assessment?"

Expert Answer:
"A comprehensive FBA follows a systematic process:

Step 1: Define the target behavior operationally and measurably. For instance, instead of 'aggression,' we might define it as 'hitting others with an open or closed hand resulting in visible contact.'

Step 2: Gather information through multiple sources—interviews with caregivers, direct observation, and review of records.

Step 3: Conduct systematic observations across different settings, times, and conditions to identify patterns.

Step 4: Develop hypotheses about the function(s) the behavior serves based on the ABC data collected.

Step 5: Test hypotheses through functional analysis when appropriate and ethical, or continue systematic data collection.

Step 6: Synthesize findings into a clear summary that identifies antecedents, consequences, and the hypothesized function(s).

The entire process should be collaborative, involving all stakeholders, and should directly inform the development of the behavior intervention plan."

Scenario-Based Questions and Strategic Responses

4. "A parent tells you they've tried everything and nothing works with their child. How do you respond?"

Expert Answer:
"I would approach this situation with empathy and professionalism. First, I'd acknowledge the parent's frustration and validate their efforts—caring for a child with challenging behaviors is genuinely difficult.

Next, I'd explain that often what appears to be 'everything' may not have included systematic, function-based interventions. I'd share that research shows interventions are most effective when they're based on understanding why a behavior occurs, not just what the behavior looks like.

I would then outline our assessment process, emphasizing that we'll work together as a team to identify what motivates their child's behavior and develop evidence-based strategies. I'd also set realistic expectations about the process, explaining that behavior change takes time and consistency.

Finally, I'd highlight the importance of their role as the parent and how their insights about their child will be invaluable to developing an effective plan."

5. "Describe a time when an intervention wasn't working. What did you do?"

Expert Answer:
"In my previous role, I was working with a teenager who engaged in property destruction when asked to complete academic tasks. We initially implemented an escape-based intervention, allowing brief breaks contingent on appropriate communication.

After three weeks of data collection, the behavior had actually increased in frequency and intensity. Rather than continuing with an ineffective plan, I immediately reconvened the team and conducted additional observations.

We discovered that the property destruction was actually serving an attention function—the dramatic responses from staff were highly reinforcing. We modified our approach to include planned attention for appropriate behaviors while minimizing reactions to the destructive behavior.

Within two weeks of implementing the revised plan, we saw a 70% reduction in property destruction. This experience reinforced the importance of continuous data monitoring and the willingness to modify interventions based on objective evidence rather than assumptions."

Ethical and Professional Questions

6. "How do you handle disagreements with other team members about treatment approaches?"

Expert Answer:
"Professional disagreements are natural in multidisciplinary teams, and I view them as opportunities for learning and collaboration. My approach follows the BACB's ethical guidelines:

First, I ensure all discussions focus on what's best for the client, not personal preferences or territorial concerns.

Second, I present data to support my recommendations, acknowledging areas of uncertainty and alternative viewpoints.

Third, I actively listen to other perspectives and look for common ground. Often, apparent disagreements stem from different priorities rather than fundamental conflicts.

If we can't reach consensus, I suggest consulting relevant research, seeking supervision, or potentially bringing in an outside expert for consultation.

Throughout this process, I maintain respect for all team members while advocating for evidence-based practices that serve the client's best interests."

7. "What would you do if a supervisor asked you to implement an intervention you believe is unethical?"

Expert Answer:
"This situation requires careful navigation of ethical responsibilities. According to the BACB Guidelines, I would:

First, respectfully express my concerns to the supervisor, citing specific ethical guidelines and explaining my reasoning.

Second, if the supervisor maintains their position, I would seek guidance from my BACB supervisor or an ethics consultant to ensure I'm interpreting the guidelines correctly.

Third, I would document all discussions and decisions for future reference.

If I determine the intervention is indeed unethical, I would decline to implement it, as the BACB Code requires behavior analysts to prioritize client welfare over professional relationships.

Throughout this process, I would maintain professionalism and focus on protecting the client while working toward a resolution that upholds ethical standards."

Industry Knowledge and Trends

8. "What current trends in ABA are you most excited about?"

Expert Answer:
"I'm particularly excited about several developments in our field:

Technology integration: The use of apps and wearable devices for data collection is making our assessments more precise and less intrusive. Research shows that technology-assisted data collection can improve accuracy by up to 45% compared to traditional paper-and-pencil methods.

Cultural responsiveness: There's a growing emphasis on incorporating cultural considerations into assessment and intervention, which is crucial given that approximately 40% of individuals receiving ABA services come from diverse cultural backgrounds.

Telehealth expansion: The COVID-19 pandemic accelerated the adoption of remote service delivery, which has shown promising results for parent training and consultation services.

Precision medicine approaches: We're seeing more individualized treatment approaches based on genetic, environmental, and behavioral factors, moving beyond one-size-fits-all interventions.

These trends represent the field's evolution toward more personalized, accessible, and culturally sensitive practices."

Data Collection and Analysis Questions

9. "How do you determine if an intervention is effective?"

Expert Answer:
"Effectiveness is determined through systematic data analysis using several criteria:

Visual inspection of graphed data to identify trends, level changes, and variability patterns.

Statistical significance when appropriate, though I emphasize that clinical significance is equally important.

Magnitude of change relative to baseline—a 10% improvement might be statistically significant but not meaningful in practice.

Maintenance over time to ensure gains are sustained beyond the intervention period.

Generalization across settings and people to ensure the skills transfer to natural environments.

Social validity measures to confirm that stakeholders view the changes as meaningful and important.

I typically look for a minimum 80% reduction in challenging behaviors or 80% mastery of new skills, but these criteria may vary based on the individual's needs and baseline performance. The key is establishing clear, measurable criteria before beginning intervention."

10. "Describe your experience with different data collection methods."

Expert Answer:
"I have extensive experience with various data collection methods, each suited to different situations:

Frequency/Event recording for discrete behaviors with clear beginning and end points. I've used this for tracking vocal requests, aggressive incidents, and completion of academic tasks.

Duration recording for behaviors where length matters, such as tantrums, on-task behavior, or social interactions.

Latency recording to measure response time, particularly useful for compliance and safety-related behaviors.

Momentary time sampling for behaviors that are difficult to count continuously, such as stereotypic behaviors or off-task behavior during lengthy activities.

ABC data collection for functional assessment purposes, capturing antecedents, behaviors, and consequences in natural settings.

I select methods based on the behavior's characteristics, setting constraints, and the precision needed for decision-making. For example, I might use frequency recording for discrete aggression but switch to duration recording if episodes become prolonged."

Communication and Training Questions

11. "How do you train staff to implement interventions consistently?"

Expert Answer:
"Effective staff training requires a systematic approach:

Baseline assessment: I first evaluate current staff knowledge and skills through observation and competency checks.

Multi-modal training: I combine didactic instruction, video modeling, role-playing, and hands-on practice to accommodate different learning styles.

Competency-based criteria: Staff must demonstrate 90% accuracy across multiple sessions before independent implementation.

Ongoing support: I provide regular feedback, booster training sessions, and troubleshooting support.

Performance monitoring: I conduct periodic fidelity checks to ensure interventions remain consistent over time.

Research indicates that comprehensive training programs can improve implementation fidelity by up to 85%. I also emphasize the rationale behind procedures, as staff who understand the 'why' are more likely to implement interventions correctly and make appropriate modifications when needed."
