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

Patient 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 model to report on the psychometric properties of the Patient Satisfaction with Navigation, Logistical measure developed for this purpose.
