Steps	Content	Module in eMotion
Step 1: Provide a rationale	People are provided with a full and comprehensive rationale for behavioral activation and PAa, including reference to the interaction of physiological, behavioral, and cognitive emotional symptoms, the role of avoidance in maintaining low mood and the idea of routine, pleasurable, necessary, and activities (including PA).	Introduction and Week 1
Step 2: Identify activities	People are helped to identify routine, pleasurable, and necessary activities (including PA)—things that they would like to do but have usually stopped doing since they became depressed.	Weeks 2-8
Step 3: Make a hierarchy of activities	People are helped to organize the activities into a hierarchy of difficulty—most difficult, medium difficult, and easiest. People should include some of each type of routine, pleasurable, and necessary activity (including PA).	Weeks 2-8
Step 4: Plan some activities	eMotion helps people to schedule some avoided activities into their week, to specify a mixture of routine, pleasurable, and necessary activities (including PA). These should be initially identified from the “easiest” category of their hierarchy from step 3). Activities should be detailed precisely: what, where, when, and with whom.	Weeks 2-8
Step 5: Implement activities	People are encouraged to undertake the planned activities. The principle of grading activities and using a mixture of routine, pleasurable, and necessary activities (including PA) should be followed. People should record if they accomplished the planned activity.	Weeks 2-8
Step 6: Review progress	People are encouraged to reflect on their progress, congratulating themselves for success and overcoming any problem-solving difficulties experienced during implementation. People may make sporadic progress and activities may not go as planned.	Weeks 3-8
