Using Data to Assess Progress

Andy’s team worked on a plan to collect data on the challenging behavior that occurred over time and the times that Andy used his social invitation card after the interventions were put in place using a line graph.

You can see from the vertical (or Y-axis) that the number of challenging behaviors that occurred were measured on the left side. On the right side of the graph on this page, you can see the number of social invitations offered. 

Days are marked on the horizontal (or X-axis). You can see the baseline period before Andy and his team started the PBS plan compared to the start of the PBS plan on September 28, 2021. 

As social invitations increased, the number of challenging behaviors decreased.

A Line Graph titled Social Invitation.  The vertical or Y-Axis respsesents the Indidents of Baseline Challenging Behavior with arrange of 0 to 4. 0 is on the bottom of the graph, and the measurments go up by .5. They are 0, .5,1,1.5,2.,2.5,3,3.5,4. The  horizontal or  X-axis indicates the date by week. It starts with September 7, 14,21,28, October 5,12,19 and 26th.  The data show that between Sept 7th and just before Sept 28 the challenging behavior occurred 1-3 times a day. On Sept 27th the Invitation card was introduced.  The challenging behaviors immedately went up to 4 the next day. The data showed that as the Invitation card was used  on a regular basis, that by Oct 5th, the number of challenging behaviors was reduced to 0-1 challenging behaviors and the number of times he used the Invitation card was increase. by October 26.  Below the graph is an Acknowledgement to the authors of  the line graph: Adapted from Freeman R., Matthews, K., Griggs, P., Quick, S.
