Objective: Evidence indicates the existence of positive effects of regular physical activity on the health of mother, child and the outcomes of pregnancy. The measurement of physical activity during pregnancy is required for planning and developing health-related interventions. This study aimed to investigate the validity and reliability of the Farsi version of the pregnancy physical activity questionnaire.
Materials and Method: This cross-sectional methodological study was conducted with a sample of 200 pregnant women living in Tabriz.Women with low-risk singleton pregnancies in the age range of 20-40 years were included the study. Sampling was carried out using the multistage sampling method in healthcare centers. Exploratory factor analysis, principal component analysis with varimax rotation, multivariate analysis of variance and Pearson correlation were used for data analysis. Reliability and internal consistency of the questionnaire were assessed using a test-retest method with a two-week interval and calculation of the Cronbach's alpha coefficient, respectively.
Results: A five-factor solution was developed:‘vulnerable people’, ‘activities related to work’, ‘home’, ‘sports’ and ‘traffic related to leisure activities’. They accounted for 43.32 percent of the observed variance. The Cronbach's alpha coefficients for the entire tool and the domains were 0.879 and 0.83-0.93, respectively. The Intra-class correlation coefficient was equal to 0.857 (CI95% = 0.75-0.93) indicating a proper stability of the questionnaire over time.
Conclusion: The Farsi version of the pregnancy physical activity questionnaire is a valid and reliable tool for examining the risk of physical activities among pregnant women in Iranian.
