Adaptação cultural e validação para a língua portuguesa de um instrumento para mensuração de gravidez não planejada (London Measure of Unplanned Pregnancy)

Abstract

Cavalhieri F.B. Cultural Adaptation and Validation for the Portuguese language of an Instrument for Measuring unplanned pregnancies (London Measure of Unplanned Pregnancy). Sao Paulo; 2011. 83 p. [Thesis School of Nursing, University of Sao Paulo]. Facing the impact that unplanned pregnancy is acquiring world wide, despite the improvement in contraceptive technologies and increasing access to health services and contraceptive methods, it is necessary to measure this phenomenon more accurately. For this reason, researchers in the sexual and reproductive health field have sought to develop measures that can provide reliable estimates of women experiencing unplanned pregnancies. Most instruments used to measure the unplanned pregnancy are unidimensional and do not take into account the partnership, the intent or the use of contraceptive methods simultaneously, a not observed aspect at London Measure of Unplanned Pregnancy (LMUP), developed in the United Kingdom. Thus, this cross-sectional study is aimed to translate and adapt the instrument LMUP to Portuguese and validate its properties, aiming at its use as an instrument for measuring unintended pregnancy in Brazil. Cultural adaptation and validation of LMUP were done according to the method recommended by the literature. The scenery for the study was units of the network of Primary Care in Marilia-SP. The studied population consisted of 126 women aged between 18 and 42 years, users of these units, who sought for this Unit to confirm the diagnosis of pregnancy by means of an immunological test for pregnancy and the result was positive. The results showed that in relation to psychometric properties, the instrument has a Cronbach's alpha value of 0.75 for the total scale. The factor analysis of the main components of the LMUP to the Portuguese version presented here has resulted in one factor, which explained 66.5% of the total variance of the data. The instrument's psychometric properties were demonstrated, and, therefore, it can be used to measure the unplanned pregnancy of the Brazilian population.
