“…The parental version had a somewhat higher Cronbach's alpha value, which can be explained by the fact that the current DKQ was based on a knowledge questionnaire that was originally developed for adults [17]. The internal validity of the current questionnaire is higher compared to previously developed knowledge questionnaires for younger Lebanese children (aged 9-11 years; alpha: 0.66) [25], and for older adolescents (aged 17-18 years; alpha ranged from 0.5 to 0.75) [41].…”

The availability of practical tools to assess dietary knowledge and adherence is essential to evaluate the effectiveness of dietary interventions. The aims of this paper were to develop reliable dietary knowledge and adherence questionnaires, suitable for Lebanese adolescents and their parents, and to estimate the feasibility of conducting studies involving such participants in the school-based setting. Eight Lebanese high schools participated in this study (involving 220 adolescents aged 15–18 years). Self-administered dietary knowledge and adherence questionnaires (the Dietary Knowledge Questionnaire (DKQ) and the Dietary Adherence Questionnaire (DAQ), respectively) were completed by the high school students and their parents. A 24 h recall was additionally administered for the adolescents by a dietitian and a trained interviewer at school, in order to validate the adolescents’ answers in the DAQ. The cognitive interview method was used to qualitatively evaluate the questionnaires. The resulting Cronbach’s alpha ranged from 0.61 to 0.78 for the adolescent questionnaires and from 0.46 to 0.89 for the parental ones. In addition, 23 items (out of 25) of the adolescent DAQ matched with the administered 24 h recall. A significant negative correlation was found between the knowledge score (DKQ) and the unhealthy items of the adolescent DAQ. There was a significant positive correlation between the DKQ of the parents and the knowledge score of their children. This is the first study of dietary questionnaires involving Lebanese high school students from different regions, while also including their parents.

“…3 Th e scale reliability was assessed using Cronbach's alpha. In an untabulated test, we obtained a score of 0.6, which according to previous studies [53,54], could be considered an acceptable value. In this regard, a lower Cronbach's alpha could be considered suffi cient to indicate consistency for scales with a reduced number of items [55] or in the case of a new scale [56].…”

This paper analyzes whether the perception of traditional wine brings value to millennials. Based on survey data and experimental auctions (165 participants), this study identifies the main factors affecting this consumer groups’ willingness to pay for traditional wine through a Tobit model methodology. The results suggest that millennials are willing to pay a higher price depending on demographic factors such as monthly disposable income, on wine involvement variables such as consumption frequency, and on nourishing and health aspects and product availability at points of sale, both of which are wine purchase decision criteria. The investigation has significant marketing and policy implications.

“…Two of the subscales 'disciplinary culture' (teacher questionnaire) and 'institutional culture'(student questionnaire) had low internal consistency in the range of .41and .46, respectively. However, subscale with value less than .40 (Cronbach's α = 0.37) has been retained in a questionnaire if it was unidimensional with fewer number of items [45], which was the case for the two subscales (Tables 4 & 5) in our study. Furthermore, values of Cronbach's alpha less than 0.7 are common for one-dimensional scales with less than 10 items and have been justi ed in the literature [46][47][48].…”

BackgroundCurriculum viability is determined by the degree to which quality standards have or have not been met, and by the inhibitors that affect attainment of those standards. The literature reports many ways to evaluate whether a curriculum reaches its quality standards, but less attention is paid to the identification of viability inhibitors in different areas of the curriculum that hamper the attainment of quality. The purpose of this study is to develop and establish the reliability and validity of questionnaires that measure the presence of inhibitors in an undergraduate medical curriculum. MethodsTeacher and student questionnaires developed by the authors were sent to medical educationalists for qualitative expert validation and to establish their content validity. To establish the response process validity, cognitive interviews were held with teachers and students to clarify any confusion about the meaning of items in the questionnaires. Reliability and construct validity of the questionnaires were established by responses from 575 teachers and 247 final-year medical students.Results Qualitative expert validation was provided by 21 experts. The initial teacher and student questionnaires containing respectively 62 items to measure 12 theoretical constructs, and 28 items to measure 7 constructs, were modified to improve their clarity and relevance. The overall scale validity index for the questionnaires was, in order, .95 and .94. Following the cognitive interviews, the resultant teacher and student questionnaires were reduced to respectively 52 and 23 items. Furthermore, after the confirmatory analysis, the final version of the teacher questionnaire was reduced to 25 items to measure 6 constructs and the student questionnaire was reduced to 14 items to measure 3 constructs. Good-for-fit indices were established for the final model and Cronbach alphas of, in order, .89 and .81 were found for the teacher and student questionnaire.ConclusionThe valid and reliable curriculum viability inhibitor questionnaires for teachers and students developed in this study can be used by medical schools to identify inhibitors to achieve standards in different areas of the curriculum.
