Psychometric Evaluation of the Patient Satisfaction With Logistical Aspects of Navigation (PSN-L) Scale Using Item Response Theory

摘要

BackgroundPatient navigation; the provision of logistical, educational and emotional support needed to help patients “navigate around” barriers to high quality cancer treatment offers promise. No patient reported outcome measures currently exist that assess patient navigation from the patient’s perspective. We use a partial independence item response theory (PI-IRT) model to report on the psychometric properties of the Patient Satisfaction with Navigation, Logistical (PSN-L) measure developed for this purpose.
