INSTRUMENT PHYSICAL ACTIVITY QUESTIONNAIRE-DISABILITY (IPAQ-D) OBSERVE TEST FOR DISABILITIES DURING COVID-19: STUDY OF VALIDITY AND RELIABILITY IN 5 COUNTRIES

Abstract

The importance of measuring physical activity (PA) for disabilities during the COVID-19 pandemic has created an urgent need for the availability of such tools. This study aims to have the advantages of a valid and reliable Instrument Physical Activity Questionnaire-Disability (IPAQ-D) observation test. The study participants were divided into two, 13 experts from five countries (Indonesia, Turkey, Greece, Portugal, and Bosnia & Herzegovina) to test the content validity. To assess reliability, 153 individuals with various disabilities (age = 12–25 years; gender = male and female) from five countries were included. Data collection techniques for the validity test of the IPAQ-D observe test use the Delphi technique. Then, data collection for reliability tests with survey techniques was carried out through observation using the IPAQ-D observe test by physical education teachers, trainers, parents, and disability companions with disabilities. Data analysis was divided into two segments, namely content validity using the manual content validity ratio (CVR) formula, while the reliability test used the test-retest reliability analysis procedure with the Pearson correlation. The results revealed that: 1) The IPAQ-D observe test instrument had high validity, 0.934. This means that this instrument is highly suitable for measuring the PA of persons with disabilities; 2) the IPAQ-D observe test instrument had high reliability, with a reliability test-retest (ICC) of 0.90 and concurrent validity (PC) of 0.917.This means that this instrument offers high consistency for measuring PAof people with disabilities. IPAQ-D observe test offers the advantage that it can measure the PA of people with disabilities, ages 12–25, with high validity and reliability, through tests and measurements conducted by observers. For future research, there is a need to develop IPAQ-D observe test considering the culture of the concerned country, but it is necessary to pay attention to the conceptual, metric, and linguistic equality of the development version with the original version (IPAQ-D observe test) in English. © 2021, Drustvo Pedagoga Tjelesne i Zdravstvene Kulture.
