1 Organizing a change teamd [27] Participants are asked to inform 1-3 significant others such as friends or family members to talk with them about their change goals, the coaching intervention itself and to keep them updated during the intervention. Implementation intention 1 Daily film clip or scientific input Behavioral activation task 1 Dashboard
2 Learning from experiences by systematic reflectionb [17] People are asked to analyze their own behavior and advance explanations for the resulting success or failure to learn from both. Questions that prompt self-explanations include: “How did you contribute to the performance?” or “How effective were you in the experience”. Then participants are confronted with questions such as “Consider a different approach that could have been taken.” And finally they should ask themselves: “What worked and what did not work? How will you behave in the future?” Implementation intention 2 Daily film clip or scientific input Behavioral activation task 2 Dashboard
3 Identifying situational/ contextual triggersb [23] Participants learn how to identify situational and contextual triggers (e.g., people, places, time in the day) that help or hinder them to show their desired behavior.

4 Thinking and writing about the pro’s and con’s of changea [15] Participants think about advantages and disadvantages of changing in the desired direction and of staying the same. This might eventually also enhance individual change motivation. Implementation intention 4 Daily film clip or scientific input Behavioral activation task 4 Dashboard
5 Learning from others by observational learningb [20, 21] Participants should look out for people in their environment, who already show their desired behavior. They analyze what these people are doing differently and try to model this behavior. Implementation intention 5 Daily film clip or scientific input Behavioral activation task 5 Dashboard
