Locus of Control

Shrink Definition

Locus of control refers to the extent to which people believe that important outcomes are primarily influenced by their own actions versus external circumstances. Individuals with a more internal locus of control generally perceive that their actions meaningfully influence outcomes. Individuals with a more external locus of control generally perceive that outcomes are influenced more by factors such as chance, circumstance, or powerful others. Most people demonstrate a mixture of both depending on the situation.

Plain language

People differ in how much control they believe they have.

Shrink Insight

The belief that action matters often influences whether action occurs.

Why it matters

Locus of control influences: • health behaviors • rehabilitation • education • leadership • workplace performance • coping • behavior change

Common misunderstanding

Neither an entirely internal nor entirely external perspective is realistic. Healthy functioning includes accurately recognizing both personal influence and external limitations.

Shrink Perspective

Control begins by distinguishing what can be influenced from what can't.

Evidence summary

Locus of control, introduced by Julian Rotter, has been extensively studied across psychology, education, rehabilitation, health psychology, and organizational science. Research suggests that perceived control influences coping, persistence, and health-related behavior, while recognizing that actual outcomes also depend on environmental and biological factors. Medical Boundary Perceived control shouldn't be confused with actual control. Many medical, psychiatric, environmental, and socioeconomic factors remain outside an individual's direct influence.
