Criterion Validity and Test-Retest Reliability of a Modified Version of the International Physical Activity Questionnaire-Short Form (IPAQ-SF) in Kidney Transplant Recipients.

ABSTRACT:

Introduction

Accelerometry, the clinically valued standard of physical activity monitoring, has limited acceptance in transplantation rehabilitation; therefore, the International Physical Activity Questionnaire (IPAQ) self-report instrument is widely used. However, while the IPAQ's repeatability is good, its criterion validity is unsatisfactory. We hypothesized that adding a concise oral introduction would help overcome this shortfall.

Materials and methods

This is a secondary analysis of a RCT in a sample of kidney transplant recipients that underwent observational follow-up. We assessed criterion validity of our modified version of the four-item IPAQ-Short Form (mIPAQ-SF) via Pearson, and test-retest reliability via intraclass correlation coefficients. The ma
