Cultural adaptation and validation of the "Pregnancy Physical Activity Questionnaire" for the Portuguese population.
Observational study in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe lack of instruments to assess the level of physical activity in pregnant women, led to the development of the PPAQ (Pregnancy Physical Activity Questionnaire), a self-administered questionnaire, which has already been translated in several countries and has already been used in several studies. AIM(S): Translate and adapt the PPAQ into Portuguese and test its reliability and validity.
methodsAn analytical observational study was carried out. Linguistic and semantic equivalence was performed through translation and back-translation and content validity was tested by a panel of experts. To test reliability, a test-retest was performed on a sample of 184 pregnant women, with an interval of 7 days and the ICC was used. To test the criterion validity, Pearson's correlation coefficient (r) was used between the PPAQ and the accelerometer, in a sample of 226 pregnant women.
findingsThe questionnaire was considered comprehensive. The ICC values of Reliability were: total score (0.77); sedentary activities (0.87); light-intensity activities (0.76); moderate-intensity activities (0.76); vigorous-intensity activities (0.70). For criterion validity was obtained a coefficient correlation of r = -0.030, considered weak and negative, for total activity. DISCUSSION: This study describes the translation and validation process of the PPAQ questionnaire from English to Portuguese. The final version of the PPAQ was considered as a valid instrument in terms of content to measure physical activity and was referred to as being simple to apply and easy to understand.
conclusionThe PPAQ has content validity, excellent reliability and weak criterion validity, as in the original version.
