Challenges inherent in implementing changes within the substance abuse treatment field can be offset by transformational leadership actions that promote innovation and attention toward individual needs and abilities. The current study developed and validated the Survey of Transformational Leadership (STL) for application in addiction treatment. Psychometric analyses confirmed nine STL themes, eight representing distinctions between commonly-noted leadership domains: Integrity, Sensible Risk (idealized influence); Demonstrates Innovation, Encourages Innovation (intellectual stimulation); Respects Others, Develops Others (individualized consideration); Task Delegation, Expects Excellence (empowerment); and Inspirational Motivation. The STL scales demonstrate good internal reliability and convergent validity when compared with scales from the Multifactor Leadership Questionnaire and the Attributes of Leadership Behavior Questionnaire. The nine themes can also be combined into a global measure of transformational leadership. Applications of the STL include informing training, selection of change agents, as well as examining relationships with organizational climate and structure.
