Development and Validation of Nutrition Literacy Assessment Instrument for Chinese Pregnant Women

Abstract

The study was designed to develop and validate the nutrition literacy assessment instrument for pregnant women in China (NLAI-P). The dimension, components and questions of NLAI-P were identified via literature review and expert consultation. A panel of experts evaluated the content validity. The construct validity was evaluated by using the exploratory factor analyses (EFA) and confirmatory factor analyses (CFA). Cronbach’s α coefficient and split-half reliability were applied for examining the reliability. The NLAI-P was divided into 3 dimensions including knowledge, behavior and skill dimension. Findings showed NLAI-P possessed the satisfactory content validity (content validity index = 0.98, content validity ratio = 0.97), acceptable construct validity (χ2/df = 1.82, GFI = 0.86, AGFI = 0.84, RMSEA = 0.046) and good reliability (Cronbach’s α coefficient = 0.82). The average scores of NLAI-P were 46.59 ± 9.27. With the adjustment of confounding factors, education level presented a significantly positive correlation with NLAI-P scores. In conclusion, NLAI-P were valid and reliable to inspect NL level of pregnant women in China. Poor NL was prevalent among Chinese pregnant women. Based on the education level, taking targeted propaganda and education measures would achieve the optimal effect. NLAI-P can be applied as the tool for monitoring and assessing NL of pregnant women, and facilitate the designation of targeted interventions policies.

Development and validation of a novel short-form nutrition literacy measurement tool for Chinese college students

“…Earlier studies identified NL measurement scales with different domains (15,(24)(25)(26)(27), or a series of specific items without considering its domains (28)(29)(30). In China, a serial of core items of NL were established for general people (31), pregnant women (32), preschool children (33), and old people (34). Based on dietary risks and dietary guidelines for Chinese people, our previous study (35) developed the NL measurement scale with 43 items (NL-43) for Chinese adults with strong reliability and validity.…”

Effects of a Comprehensive Dietary Intervention Program, Promoting Nutrition Literacy, Eating Behavior, Dietary Quality, and Gestational Weight Gain in Chinese Urban Women with Normal Body Mass Index during Pregnancy

“…The Nutrition Literacy Assessment Instrument for Pregnant Women in China (NLAI-P) is employed to measure participants’ nutritional literacy [ 53 ]. Participants respond to 38 questions across three dimensions: knowledge literacy, behavior literacy, and skill literacy.…”

Using the Theory of Perceived Value to Determine the Willingness to Consume Foods from a Healthy Brand: The Role of Health Consciousness

“…Here, the emotional usefulness and symbolic expressiveness of cultural and environmental preservation options are incorporated [48][49][50]. Evidence indicates that the high emotional value perceived in organic products increases the estimated probability of healthy purchasing the following year, increasing conscious eating behaviors [50,51]. Therefore, this hypothesis is proposed:…”
