Validity and reliability of IPAQ-SF and GPAQ for assessing sedentary behaviour in adults in the European UnionMeh, Kaja (Avtor) Jurak, Gregor (Avtor) Sorić, Maroje (Avtor) Rocha, Paulo (Avtor) Sember, Vedrana (Avtor) sporthuman activitiesexerciselifestylephysical fitnesssurveysquestionnairesself-reportpublic health surveillanceCurrent lifestyles are marked by sedentary behaviour; thus, it is of great importance for policymaking to have valid and reliable tools to measure sedentary behaviour in order to combat it. Therefore, the aim of this review and meta-analysis is to critically review, assess, and compile the reliability, criterion validity, and construct validity of the single-item sedentary behaviour questions within national language versions of most commonly used international physical activity questionnaires for adults in the European Union: The International Physical Activity Questionnaire-Short Form and the Global Physical Activity Questionnaire. A total of 1749 records were screened, 287 fulltext papers were read, and 14 studies were included in the meta-analysis. The results and quality of studies were evaluated by the Quality Assessment of Physical Activity Questionnaires checklist. Meta-analysis indicated moderate to high reliability (r$_w$ = 0.59) and concurrent validity (r$_w$ = 0.55) of national language versions of single-item sedentary behaviour questions. Criterion validity was rather low (r$_w$ = 0.23) but in concordance with previous studies. The risk of bias analysis highlighted the poor reporting of methods and results, with a total bias score of 0.42. Thus, we recommend using multi-item SB questionnaires and smart trackers for providing information on SB rather than single-item sedentary behaviour questions in physical activity questionnaires.20212022-03-08 09:34:49Članek v reviji135329sl
