Measuring Patient Satisfaction With Facial Appearance: Development and Validation of a New Patient-Reported Outcome Measure

OBJECTIVES:

• To develop and validate a new patient-reported outcome measure of quality of life related to facial appearance following oncologic head and neck resection and reconstruction.

OUTLINE:

• Part 1 (questionnaire content generation and development of preliminary instrument [post-operative patients only]): Patients undergo semi-structured interview with a trained interviewer and answer open-ended questions. Statements concerning facial appearance post-resection and reconstruction are extracted to generate items for the preliminary instrument. The preliminary instrument is developed from review of the literature, qualitative interviews with patients, and expert opinion (head and neck surgeons, reconstructive surgeons, and other relevant health care providers, including nurse clinicians). The instrument is then pre-tested on a small sample of patients via mail to clarify ambiguities in the wording of items, confirm appropriateness, and determine acceptability and completion time.
• Part 2 (field-testing with item reduction and development of final rating scale): Post-operative patients complete 2 copies of the preliminary questionnaires in the mail or clinic approximately 2 weeks apart. Pre-operative patients complete the questionnaire prior to surgery (during preoperative appointment) and again at least 1 month after surgery (via mail). Data are analyzed to determine the most valid grouping of items into measurement scales for development of the final instrument.
• Part 3 (psychometric evaluation of the patient-reported outcome questionnaire): Post-operative patients complete 2 copies of the questionnaires in clinic or by mail approximately 2 weeks apart. They also complete several other well-established, validated instruments used to measure patient-reported quality of life and symptomatology in order to aid in the evaluation of convergent and discriminant validity. Pre-operative patients complete the final questionnaire prior to surgery (during preoperative appointment) and again at least 1 month after surgery by mail or in clinic.
