Validity and repeatability of a short pregnancy leisure time physical activity questionnaire
To examine the validity and repeatability of a short leisure time physical activity questionnaire during pregnancy.
Seventynine women with uncomplicated pregnancies and weeks’ gestation ≤ 33 participated.
After the first questionnaire they entered 7-day leisure time physical activity and pedometer counts in a logbook and completed the second leisure time physical activity questionnaire. Validity was assessed with Spearman’s rank correlation coefficients by comparing the second leisure time physical activity questionnaire with pedometer counts and logbook. For describing repeatability, change in the mean, geometric mean ratio, typical error, coefficient of variation (CV,%) and Bland-Altman plots were used.
Forty-five (57%) and 47 (59%) women were available for pedometer and logbook comparisons and 49 (62%) for repeatability assessment.
The second leisure time physical activity questionnaire showed no correlation with pedometer but moderate correlation with the logbook for the frequency of moderate to vigorous-intensity leisure time physical activity.
In repeatability, the typical error for frequency estimates varied from 1.2 to 3.7 sessions and CV for duration from 119 to 369 percent. The corresponding values for systematic error were -1.0 to 0.3 sessions and 4 to 36 per cent. The 95% limits of agreement for single variables were large.
The questionnaire was valid for assessing moderate to vigorous-intensity leisure time physical activity but its individual repeatability proved weak.
