Toward Regional Use of the General Practice Physical Activity Questionnaire (GPPAQ): Reliability and Validity of the Croatian Version
Sport Mont 2025, 23(3), Ahead of Print | DOI: 10.26773/smj.251017
Abstract
The General Practice Physical Activity Questionnaire (GPPAQ) is a brief tool aimed at screening physical activity lev- els in general medical practice, but reports on its reliability and validity in languages other than English are lacking. This study aimed to evaluate the applicability, reliability and validity of the Croatian version of the GPPAQ. The par- ticipants were 158 adults (40 males, 44.2±2.8 years of age) from Croatia who were tested on translated and culturally adapted version of the GPPAQ via a test‒retest procedure. Additionally, the variables included sociodemographic data, health status, and results obtained via the International Physical Activity Questionnaire (IPAQ). The results re- vealed appropriate test‒retest reliability of the Croatian version of the GPPAQ (ICC=0.71, 95% CI: 0.60‒0.83; absolute agreement of 81%). No significant associations of the GPPAQ category with socioeconomic status, age, gender, or educational level were found. However, the activity level, as measured by the GPPAQ, was associated with the ab- sence of chronic illness (Chi-square =9.11, p<0.05) and nonsmoking status (Chi-square =11.01, p<0.05). Finally, the GPPAQ category was positively correlated with the IPAQ score (Spearman’s R=0.61, p<0.05). The Croatian version of the GPPAQ has acceptable test‒retest reliability and proper validity, confirming its applicability as a measurement tool for physical activity in primary care in Croatia but also in surrounding countries.
