Political will is widely recognized as an important, yet profoundly underinvestigated, construct that lacks conceptual clarity and valid measurement. To address this lack, we conducted four studies encompassing six samples (N = 925) from three countries (United States, Greece, and United Kingdom) that establish the psychometric properties and nomological network of the Political Will Scale. We demonstrate that the scale exhibits both convergent and discriminant validity with several conceptually related constructs while also determining that political will positively relates to influence and work-related behaviors. As an extension of our findings, political will seems to explain variance over and above political skill in relation to influence tactics, status, and career growth potential. The theoretical implications of this new scale are discussed in relation to organizational politics, leadership, and social change.
