Construct validity, floor and ceiling effects, data completeness and magnitude of change for the eight-item HAKIR questionnaire: a patient-reported outcome in the Swedish National Healthcare Quality Registry for hand surgery.

ABSTRACT:

Introduction

The aim of this study was to evaluate the construct validity, floor and ceiling effects, data completeness and magnitude of change over time for the eight-item patient questionnaire (HQ-8) in the Swedish Healthcare Quality Registry for hand surgery (HAKIR).

Methods

Construct validity was investigated through predefined hypotheses and correlation statistics between the single items in HQ-8 (pain on load, pain on motion without load, pain at rest, stiffness, weakness, numbness, cold sensitivity and ability to perform daily activities) and QuickDASH. Floor and ceiling effects and data completeness were analysed at preoperative (n = 13,197), three months (n =10,702) and one year (n = 9,986) responses from hand surgery patients. Effect sizes were
