Evaluation of questionnaire as an instrument to measure the level of nutritional and weight gain knowledge in pregnant women in Poland. A pilot study

Abstract

Pregnancy is a period in life in which women are willing to improve their lifestyle. Providing proper information for these women is crucial for their health and the health of their offspring. Clear information about weak points in their nutritional and weight gain knowledge is the first step for proper health care assistance. There are a few previous studies evaluating the nutritional and weight gain knowledge of pregnant women. In the few studies available, different approaches were taken and there was no wider discussion on the content of the questionnaires attempting to measure level of knowledge. The aim of this study, designed in a pilot fashion, was to test the adequacy of the questionnaire as a research instrument in a group of 139 pregnant Polish women. The developed instrument is a 33-item questionnaire comprising four domains: weight gain, importance of nutrients, quality and quantity of food intake. The results of this study indicate that the questionnaire is stable and internal consistency is acceptable (Cronbach's alpha > 0.7) for dimensions with more than four items. For dimensions with less than four items, internal consistency was poor (Cronbach's alpha < 0.7). The cumulative explained variance for domains weight gain, importance of nutrients, quantity and quality of food intake was 54.74%, 42.74%, 54.42% and 48.99% respectively. Results from validity, reliability and factor analysis indicate that the questionnaire is adequate for its purpose.

An evaluation of the knowledge on specific nutritional needs and factors affecting pregnancy outcome in women of reproductive age

“…The study involved a self-designed questionnaire containing single-choice, multiple-choice and openended questions. The research tool was an original 40item questionnaire that was developed for the Polish population based on the questionnaire to measure the level of nutritional and weight gain knowledge in pregnant women [18]. The questionnaire was composed of three main parts.…”

“…The survey tool comprised custom-written questions and validated tools, and was designed to capture demographics, health literacy [Health Literacy Single Question 16 and Newest Vital Sign (NVS)], 17,18 health-related quality of life [HR-QoL; Patient-Reported Outcomes Measurement Information System (PROMIS) Global Short Form for physical health (PH-PP) and mental health (MH-PP) in pregnancy and postpartum], 19 knowledge about nutritional requirements during preconception and pregnancy (nutritional knowledge, 20 dietary habits/beliefs), 21,22 sources of advice and resource utilisation, and use of routinely recommended supplements (pregnancy/preconception multivitamin or folic acid, iron, iodine, Vitamin D). 8 The single-item health literacy screening tool ('How confident are you filling out medical forms by yourself?')…”

“…The total scores for each scale are calculated by summing the item scores and dividing by the number of items in the scale; higher scores indicate better physical and mental health. In addition to these validated tools, customised questions were developed, drawing on the published literature, [20][21][22] to gather data pertaining to knowledge levels, beliefs, changes made to current habits and willingness to change.…”

“…Após o aceite, solicitou-se a assinatura do TCLE, e em seguida encaminhado o questionário no formato googleforms para identificar a caracterização sociodemográfica e por último, realizar a avaliação da TE. Para validação das respostas utilizou-se: coeficiente alfa de cronbach, índice de validade do conteúdo (IVC) e nível de concordância (Mierzejewska et al, 2020).…”
