Event Lines vs. Phase/Condition Lines Follow

Motivity offers the ability to add both event and phase/condition lines to your graphs.  There are major differences between what these lines are and how to add them.  This article will review the difference between event and phase lines.

What is an event line?

An event line is a dotted line on a graph that denotes the occurrence of an extraneous event.  An extraneous event is an environmental change that is outside of your control.  Data paths do not break across these lines.

Examples of extraneous events:

• Medication change
• School break
• New RBT added to team
• Change in family dynamic
• Etc.

Because environmental changes may affect levels of responding across multiple behaviors and skills, event lines are universally applied to targets within a program.  It can also be applied to other programs.

How do I add an event line?

• Click on the graph
• Click "+ event" in the top right corner
• Enter details of event
• Select which programs to add it to

What is a phase/condition line?

A phase or condition line is a solid line that denotes a change in the intervention.  An intervention change is a change that is intentionally implemented by the BCBA.  Data paths do break across these lines.

Examples of intervention changes:

• Adding a break card
• Implementing a new prompting strategy
• Increasing the field size
• Updating a behavior definition
• Etc.

Intervention changes are generally relevant to one or very few targets.  Due to this, phase lines are created within a program and applied to a target individually.

How do I add a phase/condition line?

• Click on the program
• Click "Edit"
• First option
  • Clone an existing phase 
    • Change phase name
    • Change any pertinent instructions
• Second option
  • Click on the "+ phase" button
    • Build phase from scratch
• Click "Update"
• Manually transition target into the new phase
