Dr. Eadie's research passion and the overarching goal of her research is to develop a clinical evaluative protocol by which speech-language pathologists can more effectively and accurately report the degree of vocal impairment, limitation in everyday activities, and psychosocial impact of voice disorders. Specifically, her team is addressing current gaps in clinical care related to a paucity of self-report instruments, as well as determining correlations between patient-reported and clinician-obtained measures.

Dr. Eadie's current research project addresses a critical gap in care for individuals who are being treated for head and neck cancer (HNC), who often report difficulties in verbal communication. While the loss of communication may lead to social isolation, traditional HNC outcome measures do not capture how individuals communicate in everyday settings, or what is known as communicative participation. Communicative participation may be defined as taking part in settings where knowledge, information, ideas or feelings are exchanged, and occurs across life situations (e.g. personal care, household management, leisure, learning, employment, and community life). The purpose of Dr. Eadie's research is to provide further validation of a new self-reporting tool called the Communicative Participation Item Bank (CPIB), which could ultimately facilitate a paradigm shift in clinical practice and research for evaluating the impact of HNC on a person's life.

In working with individuals with voice and speech disorders as a speech-language pathologist, Dr. Eadie often noted inconsistencies between the measures she obtained acoustically, measures documented using her clinical "ear" (i.e., auditory-perceptual methods), and what individuals with voice and speech disorders reported about everyday communication. Investigating the source of these inconsistencies among existing assessment tools was the "spark" that drove her interest in this field of research.
