Collecting Baseline Data Guide Collecting and graphing baseline data is essential for understanding the starting point of any target behavior before implementing interventions. This process helps in tracking progress and determining if interventions are e:ective. Here’s a guide on how to collect and graph baseline data for target behaviors: Step 1: Define the Target Behavior Clearly describe the specific behavior you want to track. The definition should be:

• Observable: It should be something that can be seen or heard. • Measurable: You should be able to count or time it in some way.

For example, if the target behavior is "o:-task behavior," a clear definition might be: "Looking away from the task for more than 5 seconds, talking to others without permission, or getting out of the seat." Step 2: Select the Measurement Method Choose how you will measure the behavior. Common methods include:

• Frequency: How often the behavior occurs (e.g., number of times a student leaves their seat).

• Duration: How long the behavior lasts (e.g., how long a child spends o:- task).

• Latency: The time between an instruction and the behavior’s occurrence (e.g., time it takes for a student to start a task after being told to do so).

• Interval Recording: Whether or not the behavior occurred during specific intervals of time (e.g., checking every 5 minutes to see if the student is on-task or o:-task).

If you have selected a structured assessment such as FAST, QABF, etc. It will automatically provide you baseline and a hypothesized function.

Step 3: Determine the Baseline Period

The baseline period is the time during which you collect data before any intervention is introduced. Ideally, you should collect baseline data over several sessions or days to ensure the data is reliable and reflects the typical behavior.

• Duration: Baseline should last at least 3-5 days or longer, depending on the behavior’s frequency or variability.

Step 4: Collect Baseline Data While collecting data, ensure consistency in your observations:

• Use the same method of measurement throughout the baseline period. • Record data during the same times of day or in the same settings. • Avoid introducing any interventions during this phase.

Step 5: Graph the Baseline Data Once you have collected baseline data, graphing it helps visualize patterns, trends, fluctuations, hypothesized function in/of the target behavior. Tools for Graphing:

• Paper/Pencil: Simple line graphs can be drawn using graph paper. • Spreadsheet Software: Programs like Microsoft Excel or Google Sheets

allow for easy data entry and automatic graph creation.

Graphing Process: 1. X-axis: Label the X-axis with the sessions or days (e.g., Day 1, Day 2,

etc.). 2. Y-axis: Label the Y-axis with the measurement of the behavior (e.g.,

frequency, duration, etc.). 3. Plot the Data: For each session or day, plot the corresponding data

point on the graph. 4. Connect the Points: Draw lines between data points to show trends

over time. Example:

• If you're tracking frequency, the X-axis could represent "Days" (Day 1, Day 2, etc.), and the Y-axis could represent "Number of times o:-task behavior occurred."

• If you're tracking duration, the X-axis might represent "Days" or "Sessions," and the Y-axis could represent the "Minutes spent on the task."

Example of Baseline Graph: • On Day 1, the student was o:-task 10 times. • On Day 2, 8 times. • On Day 3, 12 times. • The graph shows these data points with the X-axis representing days

and the Y-axis showing the number of o:-task behaviors.

Step 6: Analyze the Baseline Data • Stable Baseline: If the data shows a consistent level of behavior, it’s

easier to evaluate the e:ectiveness of an intervention. • Variable Baseline: If the data is highly variable, it might indicate that the

behavior is influenced by other factors or that more data collection is needed.

Step 7: Set Intervention Goals Using your baseline data, set realistic goals for your intervention. For example, if the student is o:-task 10 times a day on average, the goal could be to reduce that by 20% within the first two weeks of intervention. Tips for Accuracy

• Inter-observer Agreement: If possible, have another person observe the behavior at the same time to ensure data reliability.

• Objective Measurement: Avoid subjective judgments when observing behavior—stick strictly to the defined behavior.

By following these steps, you’ll have a clear visual and numerical representation of the target behavior before any interventions are made, allowing for more informed decision-making.

Assessing Behavior

Baseline

 Foundation of our intervention

 Baseline: Current levels of behavior

 Referrals for behavior  Observable

 Operational

 Quantifiable

Assessment

 Observational Assessment  Trained observer

 Assessing requires a set of skills

 Documentation of the events observed

 Circumstances under which bx takes place

After Assessment

 Determine is intervention is required

 Graphical display of data collected

 Provide only services that will benefit the client

Outside of the Observation

 Indirect assessments with more than one individual

 Need data on variability, tendencies, and function of bx

 Recommendations on services or intervention not provided without full assessment

Issues with Assessments

 Lengthy

 Stakeholders want quick fixes

 Validation of behavior with an assessment

 Qualifying an intervention is based on assessment results

Assessment Data

 Sufficient data collected to confirm that a problem behavior exists

 Obtain preliminary idea of the variables the maintain the behavior

 Baseline to evaluate effectiveness of intervention

 Explain findings clear and with graphic displays

Presenting Results, 1

 Explain functional assessment

 Reinforcement and Preference Assessment

 Request medical assessments for other conditions

 Request previous intervention information

Presenting Results, 2

 Explain limiting conditions for intervention success

 Explain expectations

 Be transparent and understandable  Buy-in

 Decisions are made on data

 This process educates about ABA
