Adaptation, Validation and Reliability of the International Physical Activity Questionnaire Short Form- Romanian version
MetadataShow full item record
Background: Accurate assessment of physical activity (PA) is important in determining the risk for chronic diseases such as cardiovascular disease, stroke, Type 2 diabetes, cancer and obesity. To monitor trends and evaluate public health, reliable and valid measures of habitual PA are essential. The aim of this study was to translate and adapt the Short International Physical Activity Questionnaire (IPAQ-SF) to the Romanian lan-guage, and to evaluate the validity and reliability of IPAQ-SF Romanian version in Ro-mania. Methods: A total of 116 apparently healthy adults (60 males), mean age 39.9 (SD ± 14.4) years, were recruited in the study. Fifty-six per cent had tertiary educational quali-fication, and 62.9% was employed. Twelve participants (6 males) of the total sample volunteered for seven consecutive days of pedometer registration as well as weight, height, heart rate and blood pressure measurement. The original English IPAQ-SF was translated into the Romanian language and subjected to pre-testing. The final Romanian version was tested in a cross-sectional study for con-current (correlation with the English version) and construct validity, and test-retest relia-bility. Results: The Romanian IPAQ-SF has good concurrent validity with Spearman correla-tion coefficients (ρ) ranging from 0.99 for total PA (Metabolic Equivalent of Task [MET]-Min week-1) to 1.00 for vigorous activity (Min week-1), but a low-moderate construct valid-ity with systolic blood pressure (mmHg) (ρ=0.03-0.41), and resting heart rate (ρ=0.11-0.40), respectively. Walking activities (Min week-1) had a significant correlation with body mass index (ρ=0.58, p0.05), and diastolic blood pressure (mmHg) (ρ=0.62, p0.05). Step counts correlated positively with questionnaire-based PA. The strongest correlation was found between step counts and total PA (ρ=0.96, p0.01). The intra-class correla-tion coefficients (ICC) for test-retest reliability were good ranging from 0.95 (CI=0.92-0.99) for walking activities, to 0.99 (CI=0.98-0.99) for total and vigorous PA. Few small differences were found in the gender and socioeconomic status specific analyses. Conclusions: The results indicate that the Romanian IPAQ-SF has acceptable concur-rent validity and test-retest reliability for vigorous- and moderate-intensity activities, walk-ing, sitting and total PA. The Romanian IPAQ-SF can be used for PA measurements in Romania but further construct validity testing on larger scale samples, and with objective measures such as an accelerometer, is needed.
