Decisional Conflict Scale

The Decisional Conflict Scale is a 16-item measure that captures uncertainty in making choices related to health, the factors contributing to this uncertainty, and an individual's self-perceived satisfaction in the decision. The measure includes items related to how decisions are informed by risks and benefits and how decisions align with personal values.
