Changing Health Goals with Personal Informatics

People’s health goals change as their contexts, needs, and values evolve. Personal informatics (PI) literature recognizes the importance of supporting goal change; however, little is known about how these tools can best support the changes people go through with their goals. To understand how PI are currently involved in goal change, we conducted a survey (N=80) and interview (N=10) study with people who had recently changed their health goals. Overall, we found that PI gave limited support to people during goal changes. Changes were driven by four actors (i.e., who and what influences the goal change): internal motivations, contexts, PI, and social surroundings. We further highlight five factors related to goal change (i.e., the ways in which the actors affect goal change): challenge, self-efficacy, changing priorities, learning, and enjoyment. We discuss how PI could better support people in goal change by considering different implementations and interactions of actors and factors.
