Spheres of Control Inventory
The Spheres of Control inventory, or SOC-3, measures the degree to which people perceive control over three spheres of life – personal achievement, interpersonal relations and social & political institutions.
Someone might be high in personal control but low in interpersonal and socio-political control, for example. Any other combination is possible, although Personal Control is usually higher than Interpersonal Control, which is usually higher than Socio-Political Control.
The self-administered questionnaire has been formulated by Delroy L. Paulhus. It is in the Public Domain, available without permission, free to download and use as needed: SOC-3 Questionnaire by Delroy L. Paulhus
