The HPQ - Development and First Administration of a Questionnaire for Hypoparathyroid Patients: The HPQ - Development and First Administration of a Questionnaire for Hypoparathyroid Patients
2019
Hypoparathyroidism patients suffer a variety of complaints often leading to reduced quality of life. Currently, no specific standard instrument exists to measure corresponding disease manifestations. We therefore aimed to develop a disease-characteristic questionnaire for hypoparathyroid patients. We used an analytical-empirical approach for questionnaire construction based on retrospective analysis of four well-established but non-disease-specific questionnaires (Symptom Checklist 90, revised [SCL-90-R]; Giessen Complaint List [GBB]; Short-Form-36 Health Survey [SF-36]; von Zerssen Symptom List [B-L Zerssen]) and two additional unpublished or local questionnaires (SHGdQ and GPQ) in a German hypoparathyroidism self-help group (n = 60). Retrospective data were compared with corresponding general population norms. The new questionnaire was administered prospectively over 1 year to patients with postoperative hypoparathyroidism and two control groups to validate specificity. Exploratory factor analysis (EFA) and reliability testing were applied to identify relevant scales and reduce overlapping items. In the self-help group, SCL-90-R revealed elevated symptom load in four complaint areas (p = 0.003 to p 0.7. The questionnaire was revised accordingly and shortened to 28 questions to avoid redundancy. We present a new disease-characteristic questionnaire for hypoparathyroidism patients. Prospective testing revealed five major complaint areas and promising psychometric properties. This questionnaire can be tested for usefulness in further clinical trials. (c) 2019 The Authors.
