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 Objectives In this cross-sectional study among 220 medical students we aimed to determine the nutritional knowledge and attitude of medical students through clinical training courses (externship and internship) of Tabriz University of Medical Sciences, Iran. A nutritional knowledge questionnaire included 51 questions was used to determine the correct, perceived and accuracy of knowledge of the participant in different aspects of nutrition sciences. The nutrition attitude questionnaire included 30 questions. Both questionnaires were confirmed in terms of the validity and reliability for assessing nutritional knowledge and attitude in this sample of Iranian medical students. Nutritional knowledge and attitude were calculated as percentage of correct or appropriate responses. Results The correct knowledge was not significantly different among externs and interns (68.20 ± 7.50% and 67.87 ± 6.04% respectively, p = 0.729). Results showed that most of the participants (49.61% of externs and 57.14% of inters) had a poor nutritional knowledge, significantly varied by age (p = 0.035). The attitude index of the subjects was not significantly different among externs and interns (73.36 ± 9.42% and 74.59 ± 9.20%, p = 0.335). Most students (92.7%) had a very appropriate attitude toward nutrition, significantly varied by sex (p = 0.010). These findings indicate that there are multiple deficiencies in nutrition knowledge of medical students.

Abstract Objective: The current study evaluated the reliability and validity of the Arabic version of the revised general nutrition knowledge questionnaire (GNKQ-R) for adults. Design: The eighty-eight-item English GNKQ-R was adapted into an eighty-six-item Arabic version. Four validation studies were conducted for internal (n 805) and external (n 106) reliability, construct validity between participants with (n 84) and without (n 88) nutrition background, convergent validity for associations between nutrition knowledge and demographic characteristics (n 750) and responsiveness to online nutrition information (n 55). Setting: United Arab Emirates University in United Arab Emirates and Hashemite University in Jordan. Participants: Undergraduate students aged 18 years and above, enrolled in any programme at the two universities, were recruited. Results: Overall, internal reliability (Cronbach’s α = 0·91) and external reliability (P = 0·350; intra-class correlation coefficient = 0·84) were high. Significantly higher GNKQ-R scores of students with (66·0 (10·6)) v. without (38·0 (10·7), P < 0·001; d = 2·6) nutrition background indicated high construct validity. Significantly higher GNKQ-R scores among females v. males, older and senior students v. younger and junior students and students in health discipline v. non-health discipline reflected good convergent validity. Significant differences in GNKQ-R scores with nutrition information (time 1 = 37·8 (10·5) and time 2 = 47·7 (9·1), P < 0·001; d = 1·0) indicated high responsiveness to nutrition intervention. Conclusions: The Arabic GNKQ-R showed high reliability and validity in the young adult Arab population. Besides the reliability of the overall questionnaire, each section demonstrated adequate reliability. Further studies are warranted to establish the generalisability and applicability of the Arabic GNKQ-R in older adults and in different middle-eastern Arab countries.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P &lt; 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Abstract Background In a context where there is no treatment for the current COVID-19 virus, the combination of self-care behaviours together with confinement, are strategies to decrease the risk of contagion and remain healthy. However, there are no self-care measures to screen self-care activities in general population and which, could be briefly in a lockdown situation. This research aims to build and validate a psychometric tool to screen self-care activities in general population. Methods Firstly, an exploratory factor analysis was performed in a sample of 226 participants to discover the underlying factorial structure and to reduce the number of items in the original tool into a significant pool of items related to self-care. Later a confirmatory factor analyses were performed in a new sample of 261 participants to test for the fit and goodness of factor solutions. Internal validity, reliability, and convergent validity between its score with perceived stress and psychological well-being measures were examined on this sample. Results The exploratory analyses suggested a four-factor solution, corresponding to health consciousness, nutrition and physical activity, sleep, and intra-personal and inter-personal coping skills (14 items). Then, the four-factor structure was confirmed as the best model fit for self-care activities. The tool demonstrated good reliability, predictive validity of individuals’ perception of coping with COVID-19 lockdown, and convergent validity with well-being and perceived stress. Conclusions This screening tool could be helpful to address future evaluations and interventions to promote healthy behaviours. Likewise, this tool can be targeted to specific population self-care’s needs during a scalable situation.

AbstractThe child anxiety impact scale-parent version (CAIS-P) is a useful measure to assess the impact of anxiety on a child’s daily life; however, a Japanese version of the CAIS-P has not been developed, and whether the CAIS-P can be utilized in Eastern countries remains unascertained. The purpose of this study was to develop a Japanese version of the CAIS-P and examine its reliability and validity. Parents of 400 children (aged 7 to 15 years) from the Japanese community completed the CAIS-P. A confirmatory factor analysis indicated that the factor structure of the original CAIS-P, consisting of school activity, social activity, and home/family activity factors, provided a good fit for the Japanese version of the CAIS-P. Estimated Spearman’s correlation coefficients showed moderate correlations between the total and factor scores of the CAIS-P, anxiety symptoms (Spence Child Anxiety Scale-parent version), and depressive symptoms (Child Depression Inventory). Furthermore, the item response theory model revealed that each factor of the CAIS-P is a high information reliable measure for children with high trait anxiety. These results provide support for the Japanese version of the CAIS-P’s factorial validity, convergent validity, and reliability and its potential for application in child anxiety research in Japan.

Straipsnyje analizuojama darbuotojų psichologinio įgalinimo problema, pristatomas lietuviškas psichologinio įgalinimo vertinimo klausimynas ir jo psichometrinės charakteristikos. Metodas parengtas dviem etapais, naudojant empirinę skalių konstravimo strategiją. Pirmajame etape, taikant grupinio interviu ir ekspertinio vertinimo metodus, parengti psichologinio įgalinimo vertinimo teiginiai. Antrajame etape atliktas empirinis tyrimas (dalyvavo 189 tiriamieji, reprezentuojantys 8 Lietuvos organizacijas). Remiantis jo rezultatais parengtas lietuviškas psichologinio įgalinimo vertinimo klausimynas. Tiriamosios faktorių analizės metodu išskirti penki faktoriai: prasmė, entuziazmas, sprendimų priėmimas, autonomija ir pasitikėjimas kompetencija. Klausimynas pasižymi dideliu vidiniu patikimumu (bendras Cronbacho α = 0,909, atskirų subskalių nuo 0,755 iki 0,880), dideliu konvergentiniu ir diskriminantiniu konstrukto validumu tiek viso klausimyno, tiek atskirų penkių skalių lygmeniu.Pagrindiniai žodžiai: psichologinis įgalinimas, psichologinio įgalinimo klausimynas, patikimumas, validumas.EMPLOYEE PSYCHOLOGICAL EMPOWERMENT: PSYCHOMETRIC PROPERTIES OF THE LITHUANIAN QUESTIONNAIREMantas Tvarijonavičius, Dalia Bagdžiūnienė SummaryEmployee psychological empowerment is treated as a multidimensional construct manifesting in several dimensions. It has been researched for several decades using various scales depending on the definition of psychological empowerment chosen by a reasercher. However, there is a lack of widely applicable, compact instruments for a reliable and valid assessment of psychological empowerment. Furthermore, there has been a lack of empowerment research in Lithuania. Therefore, the purpose of this study is to construct a Lithuanian psychological empowerment questionnaire and to evaluate its psychometric properties (reliability and validity).The strategy of the empirical construction of a questionnaire was used. At first, statements to describe the concept of psychological empowerment were generated, using group interviews and expert evaluation. Fifteen final items were included into the Lithuanian Psychological Empowerment Questionnaire (LPEQ). Then, an empirical research was performed: 189 respondents from 8 organizations filled up the LPEQ, G.M. Spreizer (1995) Psychological Empowerment Questionnaire (PEQ), B. E. Ashforth (1990) Helplessness Scale, Intrinsic Motivation Scale (Warr et al., 1979), and socio-demografic questions.The results of the study have revealed that the LPEQ has a high internal reliability (Cronbach α = 0.909). Five factors were extracted using the exploratoryfactor analysis, three items each. Psychological empowerment was defined based on five dimensions: meaning, enthusiasm, decision making, authonomy, and trust in competence. The Cronbach α was between 0.755 and 0.880 for the dimension level. These five dimensions show support for the existing models of psychological empowerment (Spreitzer, 1995; Menon, 2001), but also they supplement these models with for instance, the dimension of enthusiasm.The convergent validity of the LPEQ was confirmed by strong correlations (p < 0.01) between the LPEQ and the PEQ subscales, and the Intrinsic Motivation Scale. It was supported by a negative correlation between the LPEQ subscales and the Helplessness Scale. Based on the analysis of correlations, the discriminant validity of the LPEQ dimensions’ levels was confirmed.In conclusion, the Lithuanian Psychological Empowerment Questionnaire (LPEQ) can be characterized as an instrument with appropriate psychometricproperties for the use in research and practice. Directions for the future research in the field have been offered.Key words: psychological empowerment, psychological empowerment questionnaire, reliability, validity.

The importance of developing and assessing student critical thinking at university can be seen through its inclusion as a graduate attribute for universities and from research highlighting the value employers, educators and students place on demonstrating critical thinking skills. Critical thinking skills are seldom explicitly assessed at universities. Commercial critical thinking assessments, which are often generic in context, are available. However, literature suggests that assessments that use a context relevant to the students more accurately reflect their critical thinking skills. This paper describes the development and evaluation of a chemistry critical thinking test (the Danczak–Overton–Thompson Chemistry Critical Thinking Test or DOT test), set in a chemistry context, and designed to be administered to undergraduate chemistry students at any level of study. Development and evaluation occurred over three versions of the DOT test through a variety of quantitative and qualitative reliability and validity testing phases. The studies suggest that the final version of the DOT test has good internal reliability, strong test–retest reliability, moderate convergent validity relative to a commercially available test and is independent of previous academic achievement and university of study. Criterion validity testing revealed that third year students performed statistically significantly better on the DOT test relative to first year students, and postgraduates and academics performed statistically significantly better than third year students. The statistical and qualitative analysis indicates that the DOT test is a suitable instrument for the chemistry education community to use to measure the development of undergraduate chemistry students’ critical thinking skills.

AbstractObjective:The aim of this study was to assess the validity and reliability of a self-administered nutrition knowledge (NK) questionnaire for Italian university students.Design:The NK questionnaire included ninety questions on experts’ nutritional recommendations, nutritional content of food, health aspects of food and diets, relationship between diet and diseases, and proper food choices. It was administered to the same population under the same conditions on two different occasions with a time interval of 3 weeks between the two administrations.Setting:The survey was carried out at the University of Parma (Italy) during the 2018–2019 academic year.Participants:Data were collected for 132 bachelor and master degree students attending the University of Parma, either attending or not nutrition classes during their studies (19–30 years, 29·5 % males, 57·6 % with an academic nutrition background).Results:The questionnaire revealed high overall internal consistency reliability (Cronbach’s α > 0·8) and a good temporal stability with high correlation of the total score (r = 0·835, P < 0·001). Moreover, it showed a good ability to discriminate between subjects with potentially different NK.Conclusions:This NK questionnaire proved to be a reliable, valid and easy-to-use tool for assessing the NK of Italian university students, either with or without nutrition background.
