The State-Trait Personality Inventory (STPI) is a self-administered questionnaire designed to measure transitory and dispositional anger, anxiety, curiosity, and depression in adults. The STPI consists of eight 10-item subscales: state and trait anxiety, state and trait anger, state and trait curiosity, and state and trait depression. The "state" items aim to assess a subject's current emotional state, and are rated on a four-point intensity scale. The "trait" items aim to assess the subject's emotional disposition, and are rated on a four-point frequency scale.
