Locus of control is a measure of the extent to which an individual perceives the events in their life to be determined by their own actions. A strong internal locus of control indicates that an individual perceives the events in their life to be determined by their own actions. For example, a student with a strong internal locus of control will, upon receiving a high grade, reflect that their diligence and attentiveness has paid off. On the other hand, a student with a strong external locus of control might consider their high grade an indication that their teacher is a 'soft marker'. A strong internal health locus of control, especially in combination with a high value on good health, is correlated with health-seeking behaviour and health outcomes. Sudden, negative events have physical, emotional, and financial impacts. They can also cause injury to perceived locus of control. Injury to locus of control can have profound and enduring consequences for these 3 domains.
