Step 3.1 Gather and record data

Develop a system to monitor the effectiveness of the intervention that outlines where, when, by whom, and how data are collected.

Monitor the frequency and duration of the interfering behavior and the

replacement behavior

Collect data to monitor the toddler's progress. Data will be collected at planned time periods by taking language samples and/or other data (for example, frequency counts) on strategies that were used to elicit the targeDt behavior. Because naturalistic intervention involves having the conversational partner engaged with the toddler, it can be helpful to either:

video record the session and collect data off the video at a later point in time or
have an observer take the data.

However, this may not always be possible, especially in home-based settings where real-time data collection is the most feasible. Then, the interventionist or parent would want to use data collection measures and procedures that are easily accessible during intervention and efficient. This may involve making marks on a piece of masking tape applied to a hand or selecting off tallies on a tablet or smart phone.

View a sample data collection form that shows how data could be gathered on the intervention, including routines in which the intervention was embedded, environmental arrangements, and naturalistic intervention strategies that were used to elicit the target behavior. This data collection is set up to show one way to collect and code the outcomes from implementing naturalistic interventions in the video segments of Gus’s snack pack sessions in the Step 2 Practice Scenario Activities.

Target Behavior:
Gus will use his words to request a snack item from a peer on three occasions during a 30 minute “Snack Pack” session two mornings a week.
Gus will respond to a peer’s request to pass a snack with a verbal response (e.g. Here you go, Joe) and a physical action (e.g., pass the bowl of snacks) on three occasions during a 30 minute “Snack Pack” session two mornings a week.

Example of data collection procedures that may be used real time in home and center-based settings:

Wrapping paper or masking tape around one’s wrist on which data can be tallied.

This procedure allows parents and other intervention team members to move around the home or center space without having to carry data collection sheets.

Placing data collection sheets near the location of the activity.

In a home, this may mean placing laminated sheets next to the bathtub during bath time or placing a data sheet on the refrigerator.

In a center-based program, the data sheets would be placed near each space an activity occurs that they are available everywhere the toddler spends time.

Gathering data from multiple toddlers in a center-based group on address labels that can later be peeled off and put on individual toddlers’ data sheets.

Using this procedure, team members will avoid having to shuffle through multiple data sheets as they interact with a classroom of students.

Using technology such as tablet or smart phone to click off data.

These types of technology devices often include a stop watch to help with recording time intervals.

These devices are also portable and may be easily moved throughout the home or center-based setting.
