Abstract: The present article reviews recent research on motivational factors that influence the success of personal goals. Although achieving progress on personal goals is made difficult by limitations in self-regulatory strength, it is argued that individuals who feel autonomous regarding their goals will benefit in distinct ways. The issue of autonomy concerns whether a goal reflects an individual's interests and personal values versus whether it is adopted because of social pressures or expectations of what an individual "should do." Recent research indicates that autonomous goal motivation can lead directly to greater goal progress by allowing individuals to exert more effort, experience less conflict, and feel a greater sense of readiness to change their behaviour. It also allows individuals to make better use of implementation plans specifying how, when, and where they will enact goal-directed behaviours. Support from other people (health care providers, etc.) can play a vital role in facilitating goal pursuits, especially when such support enhances feelings of autonomy. Successful goal progress results in enhanced positive affect and reduced negative affect, particularly if the goal pursuits involved satisfaction of intrinsic psychological needs.
