Data Collection Documentation in ABA

Data collection is the systematic recording of information about behaviors, skills, and interventions. As an RBT, you’ll be responsible for collecting accurate, consistent data that informs clinical decision-making. Proper data collection documentation ensures that progress can be objectively measured and interventions can be evaluated for effectiveness.

Purpose of Data Collection Documentation

Systematic data collection serves several critical functions:

1. Measuring Progress

Establishing baselines: Documenting initial performance levels
Tracking improvement: Measuring changes over time
Goal evaluation: Determining if objectives are being met
Skill acquisition: Monitoring learning of new abilities
Behavior reduction: Tracking decreases in challenging behaviors

2. Guiding Intervention Decisions

Treatment modifications: Informing changes to procedures
Reinforcement adjustments: Guiding changes to reinforcement schedules
Prompt fading: Determining when to reduce prompting
Goal updates: Indicating when to modify or add goals
Discharge planning: Supporting decisions about service continuation

3. Communication and Accountability

Team coordination: Sharing objective information among providers
Caregiver updates: Providing concrete evidence of progress
Funding justification: Supporting continued service authorization
Quality assurance: Demonstrating intervention effectiveness
Research contribution: Adding to the evidence base for interventions

Practice Example

An RBT is collecting data on a 5-year-old client’s compliance with instructions during a therapy session. The behavior intervention plan requires documentation of the frequency of compliance, latency to respond, and ABC data for any instances of non-compliance.

Question: What should be included in the data collection documentation for this session?

Solution:

Comprehensive Data Collection Documentation:

Basic Information Section:

Client: A.B. (ID #12345)
Date: 10/15/2023
Session time: 9:00 AM - 11:00 AM
Setting: Clinic therapy room
Observer: Sarah Johnson, RBT
Supervisor: Dr. Williams, BCBA
Target behavior: Compliance with instructions

Operational Definition Section:

Compliance: Initiating the requested action within 10 seconds of instruction delivery without problem behavior and completing the action as specified.

Non-compliance: Failure to initiate requested action within 10 seconds, refusal statements, or engaging in problem behavior following instruction.

Frequency Data Section:

Total instructions delivered: 15
Number of compliant responses: 12
Compliance percentage: 80%

Instructions by type:
- One-step instructions: 10 delivered, 9 compliant (90%)
- Two-step instructions: 5 delivered, 3 compliant (60%)

Latency Data Section:

Average latency to compliance: 4.2 seconds
Range of latency: 1-8 seconds

Latency by instruction type:
- One-step instructions: 3.1 seconds average
- Two-step instructions: 6.5 seconds average

ABC Data for Non-Compliance:

Episode 1:
Time: 9:25 AM
Antecedent: Two-step instruction: "Put the blocks in the bin and come sit at the table"
Behavior: Continued playing with blocks, did not respond to instruction
Consequence: Instruction repeated with gestural prompt
Result: Complied after prompt
Possible function: Escape from less-preferred activity

Episode 2:
Time: 10:15 AM
Antecedent: Two-step instruction: "Close the book and get your crayons"
Behavior: Said "No, I'm reading" and continued with book
Consequence: Offered choice: "You can finish this page, then we'll color, or we can color now and read again later"
Result: Chose to finish page, then transitioned to coloring
Possible function: Escape from transition

Episode 3:
Time: 10:40 AM
Antecedent: One-step instruction during non-preferred activity: "Write your name"
Behavior: Pushed paper away and said "I can't"
Consequence: Provided verbal prompt and partial physical guidance
Result: Completed with prompting
Possible function: Escape from difficult task

Analysis and Patterns Section:

Compliance patterns:
- Higher compliance with one-step vs. two-step instructions
- Faster response to preferred activities
- Non-compliance more likely during transitions and non-preferred tasks
- Compliance improved following reinforcement of previous instruction

Intervention effectiveness:
- Offering choices effective for transition-related non-compliance
- Visual supports reduced latency for two-step instructions when used
- Token economy maintained high compliance with one-step instructions

Recommendations Section:

Suggested modifications:
- Increase use of visual supports for two-step instructions
- Implement 5-second warnings before transition-related instructions
- Continue choice-making opportunities during transitions
- Consider breaking down non-preferred tasks into smaller steps

Data collection adjustments:
- Add specific tracking of compliance during transitions vs. during activities
- Separate data for instructions with and without visual supports

This comprehensive documentation provides a complete picture of the client’s compliance behavior, including patterns, influencing factors, and recommendations for intervention modifications. It includes all required elements: frequency data, latency measurements, and ABC analysis for non-compliance episodes.
