Knowledge Questionnaire

Nutrition knowledge refers to understanding concepts and processes related to nutrition and health, proven to be an essential determinant of healthy eating. However, partially due to the lack of nutrition knowledge and unhealthy eating patterns, more and more Chinese people face overweight, obesity, and a high risk of suffering from various chronic diseases. This study aimed to develop a general nutritional knowledge questionnaire (GNKQ) in a Chinese context to diagnose and improve nutrition knowledge education for Chinese people. The newly adapted questionnaire was based on the Turkey version of GNKQ, and absorbed dietary recommendations in a Chinese context. It was first validated by four nutrition experts, then tested by eleven volunteers (one public nutritionist, one preventive medicine graduate student, and nine psychology graduate students). Finally, the questionnaire was tested by 278 participants, including 175 adults, to determine internal consistency, content validity, and convergent validity. Moreover, the construct validity was evaluated by comparing the differences between 50 students in nutrition-related majors and 53 students in nutrition-unrelated majors. The final Chinese version of GNKQ kept 32 questions with 68 items after deleting some questions based on item difficulty and discrimination. The data showed that the overall internal consistency coefficient was 0.885, and the test-retest reliability was 0.769, p < 0.001. Students majoring in nutrition had larger scores than in nutrition-unrelated majors. The convergent validity for each demographic variable was consistent with previous studies, such as larger nutrition knowledge scores for females and those with a higher education. Therefore, the revised Chinese version of GNKQ showed good reliability and validity, indicating that it could be an effective tool to assess the nutrition knowledge of Chinese adults.

Knowledge Questionnaire

Abstract Objectives To assess validity and reliability of a nutrition knowledge questionnaire originally developed for adults when used with high-school aged adolescents. Methods The nutrition knowledge questionnaire utilized in this study was originally developed for adults and was shown to have content and construct validity as well as internal consistency and test-retest reliability. Two sections of the adult questionnaire, 50 questions total, were administered to adolescents at four high schools: three in California and one in Hawaii. Participants were convenience samples selected by teachers at each school based on known previous nutrition education (n = 174) or no known previous nutrition education (n = 136). Adolescents self-reported their current age and received a $10 gift card for completing the questionnaire. Questionnaire data were assessed for item difficulty, item discrimination with item-total correlation, and construct validity using an independent samples t-test. The overall questionnaire and individual sections were assessed for internal consistency reliability with Cronbach's alpha. Given the difference in nutrition education offered at each site, a post-hoc regression analysis was conducted to assess % correct by group when controlling for school. Results Assessment of item difficulty showed that one question exceeded the suggested 80% threshold, however this question was retained due to acceptable item discrimination. One question was found to negatively correlate with total score and was removed from the questionnaire resulting in 49 questions. The overall questionnaire was shown to have internal consistency reliability (Cronbach's α = 0.83) as were the individual sections (Cronbach's α &gt; 0.70). The questionnaire also demonstrated construct validity with the adolescents that had known previous nutrition education having a significantly higher mean % correct compared to the adolescents without known nutrition education (P &lt; 0.0001). The significant association between groups and % correct remained when controlling for school (P &lt; 0.0001). Conclusions Results suggests that the questionnaire was shown to reliably assess general nutrition knowledge in high school-aged adolescents with validity.

Insomnia Severity

Background Occupational balance, a fundamental concept in occupational therapy, is the arrangement of right amount and variety of occupations contributes to a person’s health and well-being. This study was aimed to investigate the reliability and validity of the Chinese version of the Occupational Balance Questionnaire (OB-Quest) for people with insomnia. Methods The OB-Quest was translated into traditional Chinese and reviewed by an expert panel for content validity, cultural relevance and translation accuracy. Internal consistency, factor analysis and convergent validity, as well as test–retest reliability, were explored. Results The participants (n = 205), 115 adults with insomnia and 90 adults without insomnia, completed a survey of demographic background, the Chinese version of OB-Quest and the Chinese Insomnia Severity Index (C-ISI). The Chinese version of OB-Quest demonstrated excellent test–retest reliability (ICC= 0.98) and good internal consistency (Cronbach’s α  =  0.80). Factor analysis indicated that a single-factor solution explained 42% of the variance, and 9 out of 10 items had a factor loading of 0.4 or above. The Chinese version of OB-Quest had significant correlations with C-ISI (r = –0.88; p < 0.001). A significant difference was found in occupational balance between groups with different levels of insomnia severity and without insomnia (F = 169.72; p < 0.001). As in a previous study, age, living environment and life role had no significant relationship with occupational balance. Conclusion The Chinese version of OB-Quest is a short, easy to understand and culturally relevant assessment for Chinese. It demonstrates satisfactory psychometric properties and had significant correlations with insomnia.

Purpose: To develop and psychometrically test a comprehensive measure of preconception health knowledge. Design: Cross-sectional survey, in May and June, 2019. Setting: Alberta, Ontario, and Québec, Canada. Sample: One thousand seven hundred seventy-seven women and men with ≥1 children born in the last 5 years or planning a pregnancy in the next 5 years. Measures: Using prior literature and input from public health nurses and physicians, the Preconception Health Knowledge Questionnaire (PHKQ) was developed and comprised 25 multiple choice questions on reproductive history, sexual health, infectious diseases, chronic medical conditions, mental health, medications, immunizations, lifestyle behaviors, psychosocial stressors, and environmental exposures. Analysis: Psychometric testing was undertaken to evaluate item difficulty, discrimination, quality of response alternatives, internal consistency, and construct validity. Results: Participants had a mean total score of 15.8/25 (SD = 3.9); women and men had mean total scores of 16.2 (SD = 3.6) and 13.8 (SD = 4.7), respectively. Most items were neither too difficult nor too easy, discriminated well between participants with high and low knowledge, and had appropriate response alternatives. High internal consistency (KR-20 = 0.87) and construct validity, shown via significant correlations with education level and previous preconception care receipt, were demonstrated. Conclusion: The PHKQ is a reliable and valid tool for measuring preconception health knowledge and may be useful in identification of high-risk groups in need of preconception health education and evaluation of preconception health interventions.

AbstractWorkplace dietary intervention studies in low- and middle-income countries using psychometrically sound measures are scarce. This study aimed to validate a nutrition knowledge questionnaire (NQ) and its utility in evaluating the changes in knowledge among participants of a Nutrition Education Program (NEP) conducted at the workplace. A NQ was tested for construct validity, internal consistency and discriminant validity. It was applied in a NEP conducted at six workplaces, in order to evaluate the effect of an interactive or a lecture-based education programme on nutrition knowledge. Four knowledge domains comprising twenty-three items were extracted in the final version of the NQ. Internal consistency of each domain was significant, with Kuder–Richardson formula values>0·60. These four domains presented a good fit in the confirmatory factor analysis. In the discriminant validity test, both the Expert and Lay groups scored>0·52, but the Expert group scores were significantly higher than those of the Lay group in all domains. When the NQ was applied in the NEP, the overall questionnaire scores increased significantly because of the NEP intervention, in both groups (P<0·001). However, the increase in NQ scores was significantly higher in the interactive group than in the lecture group, in the overall score (P=0·008) and in the healthy eating domain (P=0·009). The validated NQ is a short and useful tool to assess gain in nutrition knowledge among participants of NEP at the workplace. According to the NQ, an interactive nutrition education had a higher impact on nutrition knowledge than a lecture programme.

AbstractObjective:To develop and validate a Dental Nutrition Knowledge Competency Scale to assess dental health-related nutrition knowledge of low-income women.Design:This is a cross-sectional study. A literature search for foods/dietary practices related to dental caries was conducted and the items were incorporated into an initial questionnaire. A panel of ten nutrition experts evaluated it for its content, readability and relevance, and a focus group of six low-income women determined its readability and comprehension. Then the questionnaire was administered to 150 low-income women. Construct validity was evaluated by item difficulty, item discrimination and factor analysis. Internal consistency reliability was tested via Cronbach’s α. In a sub-sample of forty women, test–retest reliability was established. Paired-sample t tests were conducted to examine differences between test scores at the two time points, 2 weeks apart.Settings:Community centres in low-income housing in Central Texas, USA.Participants:A total of 150 low-income women, aged 18–50 years; annual household income <250 % of the federal poverty level.Results:Item difficulty and discrimination analysis resulted in elimination of eight questions. Factor analysis identified twenty-four items that loaded on three factors related to knowledge. These included foods/dietary practices that affect dental caries, added sugars in foods and on food labels, and recommended frequency of oral hygiene practices. The subscales and the completed scale exhibited good internal consistency (mean 0·7 (sd 0·97)) and test–retest reliability (mean 0·8 (sd 0·013)).Conclusions:The Dental Nutrition Knowledge Competency Scale is a validated and reliable instrument to assess nutrition knowledge related to dental health in low-income women.

The English version of the Independent Television Commission-Sense of Presence Inventory (ITC-SOPI), which was developed in 2001 to measure how involved or present participants are when experiencing different media, has substantial psychometric evidence. This study was used to translate and validate the ITC-SOPI in interactive virtual environments among the Chinese population. We used the forward-backward translation procedure. An expert panel reviewed the translated ITC-SOPI until the Chinese version of the ITC-SOPI was finalized. A total of 210 participants (133 males and 77 females), with a mean age of 23.05 years ( SD = 3.56, range = 17–47), completed the Chinese ITC-SOPI. The following psychometric properties were examined: factor structure, internal consistency, test–retest reliability, and convergent validity. Confirmatory factor analysis (CFA) showed a good fit (χ2 /df = 1.70, Tucker–Lewis Index [TLI] = 0.91, comparative fit index [CFI] = 0.92, root mean square error of approximation [RMSEA] = 0.058) of the four-factor model (spatial presence, engagement, ecological validity, and negative effects). For each factor, the Chinese ITC-SOPI had high internal consistency (Cronbach’s α ranging from 0.75 to 0.87) and test–retest reliability (intraclass correlation coefficient ranging from 0.82 to 0.91). Significant correlations were identified between all factors and the Interpersonal Reactivity Index-C (IRI-C) and the Generalized Anxiety Disorder-7 (GAD-7). The Chinese ITC-SOPI had good psychometric properties, suggesting that it is a reliable and valid tool for evaluating media users’ sense of presence in a Chinese-speaking context.

Abstract Background Nutritional knowledge assessment is an important component in nutrition research, and a prerequisite for the implementation of many policies and programs aimed at improving eating behavior. In order to generate objective results, validated tools for a given population must be employed. The aim of this study was to determine the validity and reliability of a nutrition knowledge questionnaire for Romanian adults. Methods Kleimann’s version of a General Nutrition Knowledge Questionnaire, was translated and adapted to Romanian language, culture, and cuisine. The final format was developed in several steps and used four components: internal and external reliability were assessed in a general population sample (n1 = 412), respectively in a subgroup (n2 = 46) from Component 1; Component 3 assessed construct validity (n3 = 96) using the “known-groups” method; Component 4 (convergent validity, n4 = 508) tested the association between socio-demographic characteristics and nutrition knowledge. Results The overall internal reliability was 0.878 and the external reliability was >0.880 in all sections, and overall. Specialists had higher scores than nonspecialists, with a very large effect size. In the general population, females scored higher than males, and middle-aged and older adults scored higher than young adults. Higher scores were associated with higher levels of education. The characteristics of individuals prone to giving wrong answers were: males (beta = 0.170), high school or less (beta = 0.167), and no training in nutrition (beta = 0.154). Conclusions The Romanian version of the General Nutrition Knowledge Questionnaire is a reliable and valid tool for measuring nutrition knowledge in adults.

Abstract Two studies were conducted to validate the Ambivalent Ageism Scale in China. In the first study, 474 Chinese adults (18-58) were asked to take the Chinese version of the AAS. EFA exhibited a similar factor solution as the original study, with high internal consistency and construct validity. Moreover, in a second study, 372 Chinese adults (18-85) took the AAS and provided their estimations of the similarities between their current and their past/future self via the SIC. Results indicated that all three factors of the SIC positively related to hostile ageism, whereas succession and identity positively related to benevolent ageism and consumption negatively related to it. Additionally, past self-continuity was positively associated with hostile ageism, and future self-continuity was negatively associated with it, but neither form was associated with benevolent ageism. These results further validate the AAS in China and also provide evidence for the uniqueness of benevolent ageism.

Abstract Background The Pittsburgh Fatigability Scale (PFS) was developed to capture fatigue and demand in a single tool, filling a gap that no validated questionnaire existed to measure perceived fatigability. Since fatigability is a more sensitive measure of a person’s susceptibility to fatigue, we validated the simplified-Chinese version of the PFS among Chinese community-dwelling older adults. Methods This cross-sectional study was conducted in an urban community in Beijing between November 2018 and July 2019. The PFS was translated into simplified-Chinese by the translation, retro-translation method. Internal consistency of the Physical subscale of the PFS was evaluated by Cronbach’s alpha. Convergent validity and discriminant validity were evaluated against physical performance measures (i.e., Short Physical Performance Battery & Timed Up and Go Test) and daily living performance (i.e., Barthel Index & Instrumental activity of daily living). Results Our study included 457 participants, including 182 men (39.8%) and 275 women (60.2%). The age range of the included participants was 61–96 years (mean = 84.8 years, SD = 5.8 years). The simplified-Chinese version of PFS Physical scores showed strong internal consistency (Cronbach’s alpha = 0.81). Higher PFS Physical scores were associated with worse physical performance, and daily living performance (|correlation coefficient| range: 0.36–0.56, p < .001). Age- and sex-adjusted PFS Physical scores had moderate to good overall discrimination for correctly classifying people by their physical performance and daily living performance (AUCs range 0.70–0.87, p < .001). Conclusions The PFS simplified-Chinese version is a valid instrument to assess perceived physical fatigability in Chinese-speaking older adults with good convergent validity. Thus, the PFS, with low cost and greater feasibility, is a desired tool to measure fatigability in large population studies.
