Professional Writing in the Health Disciplines is a resource for graduate students to enhance their competency in professional writing. It is designed for self-study, with exercises and activities to support mastery of the concepts and processes presented. Readers are guided through the process of developing their own voice, actively engaging with and thinking critically about the ideas of others, crafting a thesis and argument, reflecting and integrating the voices of others with scholarly integrity, and editing their paper to comply with professional standards of the American Psychological Association. Instructors are invited to use this resource to support instructional design of graduate courses and grading of assignments.
