All data collection instruments must be valid and reliable for the nurse to be able to intervene effectively enabling her to propose health policies that pursue the reduction of maternal and perinatal morbidity and mortality. The general objective of this study was to determine the validity and reliability of the questionnaire named "Self-care practices of women during postpartum period". It is a methodological research. Content validity conducted through the experts test reported a score of 0,88; the face validity with 10 experts and 10 women in a postpartum stage evidenced a consensus of agreement in relation with the clarity and comprehension of the questionnaire. A pilot test was conducted to determine possible adjustments. With participation of 176 postpartum nursing mothers from different socio-economic strata, residing in Bogotá, to whom, prior informed consent, a 32 item questionnaire was applied. A database was put together in Excel and data were processed in SPSS version 12.0. The scale validity showed that it is a short scale; discriminating validity determined 12 items that had a greater correlation and grouped those that had low correlations. The reliability of the 32 item questionnaire presented a Cronbach´s alpha of 0,59 and the 12 item questionnaire a Cronbach´s alpha of 0,68, which is considered an acceptable and a good score in the first validation studies of an instrument. The reliability of the questionnaire permeates all validation processes, reason why its interpretation must go hand in hand with continued validity improvement.
