Reliability and Validity of Patient Reported Outcome Measures in Head and Neck Cancer

This study is a cross-sectional, questionnaire-based psychometric study. The purpose of the
study is to: (1) use Rasch methodology to assess the reliability, construct validity, and
overall appropriateness of test score interpretation of 5 shoulder-related patient reported
outcome measures in patients experiencing shoulder dysfunction following neck dissection
surgery for head and neck cancer; and (2) based on these findings, provide recommendations of
which patient reported outcome measure or combination of measures most accurately reflects
shoulder disability in patients who experience shoulder dysfunction following neck dissection
surgery. Two-hundred and fifty subjects will be recruited during regularly scheduled clinical
visits at Mayo Clinic. Subjects will complete five shoulder-related patient reported outcome
measures on only one occasion, therefore subjects will be responsible for study participation
only at the time of enrollment and same day completion of study-related documents. Upon the
conclusion of data collection, Rasch analysis will be utilized to analyze data related to the
research objectives, and descriptive statistics will be utilized to describe the sample.
