Professional Identity Scale (PIS)

The PIS is a self-report questionnaire measuring healthcare students' sense of professional identity, belonging, and commitment to their chosen discipline. Developed by Adams and colleagues in 2006, the PIS assesses the degree to which students have internalized professional roles, values, behaviors, and career commitment. The scale measures both cognitive elements (knowledge of professional standards and scope of practice) and emotional elements (sense of belonging, pride in discipline). The PIS is used in healthcare education to track professional identity development over training, identify students at risk of attrition, and evaluate the impact of socialization experiences on disciplinary commitment.
