Psychological Empowerment Scale
The Psychological Empowerment Scale is Gretchen Spreitzer's measure of empowerment as an internal motivational state, defined by four cognitions: meaning, competence, self-determination, and impact. It operationalizes the interpretive model of Thomas and Velthouse, who in 1990 recast empowerment not as a managerial act of delegating power but as intrinsic task motivation reflected in how workers experience their roles. Spreitzer's 1995 Academy of Management Journal paper developed and validated a multidimensional scale, using confirmatory factor analysis across two samples to show that the four dimensions combine into a higher-order empowerment construct. She then situated empowerment in a nomological network of antecedents and consequences, linking it to managerial effectiveness and innovative behavior. The scale gave the field a concise, validated instrument and established psychological empowerment as a measurable state distinct from structural or relational notions of empowerment.
