Measurement properties of the incremental step test for people with chronic obstructive pulmonary disease: a cross-sectional study.

ABSTRACT:

Objectives

The new incremental step test (IST) is a field test that was developed for people with chronic obstructive pulmonary disease (COPD), based on the characteristics of the incremental shuttle walk test (ISWT); however, its measurement properties still need to be determined. We aimed, first, to assess the construct validity (through the comparison with the ISWT), within-day reliability and measurement error of the IST in people with COPD; and, second, to identify whether the participants have a learning effect in the IST.

Design

Cross-sectional study, conducted according to COnsensus-based Standards for the selection of health status Measurement INstruments guidelines.

Setting

A family health unit in Portugal, April 2022 to June 2023.
