“…Differences between high and lower nutrition-literate individuals have also been reported in many previous validation studies. [9][10][11][12][13] The PKM-11 scale correlated moderately with the GNKQ, confirming that both measure nutrition knowledge, although not exactly the same nutrition knowledge type.…”

“…7,14,18 To further validate the scale, the PKM-11 scores were compared between dietitian trainees and laypeople, which is a common method used in previous scale validations. [9][10][11][12][13] In Study 4, the reliability was examined using a test-retest, which was expected to achieve a minimum recommended value of r = 0.70 for a good test. 29…”

“…8 More precisely, most of the existing nutrition knowledge questionnaires assess general knowledge, which might not be appropriate for predicting specific behaviors such as choosing low-energy food. 7,[9][10][11][12] In addition, general nutrition knowledge questionnaires, such as the widely used questionnaire of Parmenter and Wardle, 13 are very time-consuming and contain several items of questionable relevance. To better explore the impact of nutrition knowledge on food intake, reliable and valid questionnaires are thus required to measure a specific (unidimensional) and relevant type of nutrition knowledge.…”

“…Scores were calculated by adding each item score together to achieve an overall total score. The nutrition knowledge survey assesses knowledge on food consumption from sodium to fat to overall healthy meals [15]. This survey was scored by adding the numbers that were correct together to achieve a total score out of a maximum 40 points.…”

The Role of Race and Gender in Nutrition Habits and Self-Efficacy: Results from the Young Adult Weight Loss Study

et al. 2017

Overweight and obesity are a massive public health problem and young adults are at high risk for gaining weight once they enter a college. This study sought to examine gender and race as they relate to nutrition habits and self-efficacy in a population of diverse young adults from the Young Adult Weight Loss Study. Participants (N = 62) were 29% males, 38.7% white, 33.8% Asian, and 12.9% African American. Males had lower self-efficacy for healthy eating (mean score = 92.5, SD = 17.1) compared to females (mean = 102.3, SD = 13.7, p = 0.02). Males had higher consumption of sodium compared to females (4308 versus 3239 milligrams/day, p = 0.01). There were no significant differences across racial subgroups in self-efficacy for healthy eating (p = 0.67) or self-efficacy for exercise (p = 0.61). Higher self-efficacy scores for healthy eating were significantly associated with less total sodium (r = −0.37, p = 0.007), greater fruit consumption, and less saturated fat. Our results indicate that weight loss interventions should be individualized and that there may be specific areas to target that are different for men and women. Additional larger studies should be conducted to confirm if racial differences exist across nutrition habits and self-efficacy and to confirm gender differences noted in this study.

“…So we want the questionnaires that consider both aspects of psychometric validation and nutrition knowledge, as well as dietary habits. Nutrition knowledge questionnaire for adults (NKQA) (11), and the dietary habits and nutritional knowledge (DHNK) questionnaire (12) together are included nutrition knowledge and dietary habits and also consider psychometric validation. There is no overlap or similarity in nutrition knowledge questions between two questionnaires.…”

Background: Overweight in adults has increased significantly in developed countries in recent decades. This problem has attracted interests of researchers in the field of nutrition knowledge. Objectives: The purpose of this study is to evaluate the validity and reliability of the Persian version of the dietary habits and nutritional knowledge questionnaire and the nutrition knowledge questionnaire for adults, and to confirm their structural model in the Iranian population. Methods: A sample of 300 hospital employees from a hospital in Mashhad, Iran, participated in this study and completed the questionnaires. The questionnaires were translated using the forward-backward translation method. Psychometric evaluation of the Persian version of the questionnaires with a total 5 subscales was assessed based on content validity and construct validity using confirmatory factor analysis. Internal consistency and test-retest reliability were evaluated using Chronbach's alpha and intra-class correlation coefficient, respectively. Results: For qualitative content validity, the content validity index scores for all items were ≥ 0.80 and the content validity ratio scores were 0.91, 0.87, 0.84, 0.9, and 0.85 for all subscales. The Persian version of the questionnaires were confirmed by calculating confirmatory factor analysis models fit indices. The internal consistency figures for the Nutrition knowledge questionnaire for adults subscales were 0.7, 0.75, and 0.73 and for the total scale was 0.78; for the dietary habits and nutritional knowledge questionnaire were 0.71 and 0.7 and for the total scale was 0.74. The intra-class correlation coefficient were 0.97 and 0.95 for the total scale of nutrition knowledge questionnaire for adults and the total scale of dietary habits and nutritional knowledge questionnaire respectively. Conclusions: The findings show that the Persian version of the questionnaires has good content validity as well as acceptable validity and reliability.
