Abstract Objective: This study aimed to validate a nutrition knowledge questionnaire appropriate for use in Australia. Design: Nutrition knowledge is essential in establishing and maintaining strategies that reduce the burden of disease and promote wellbeing. The General Nutrition Knowledge Questionnaire (GNKQ) was developed in the United Kingdom in 1999 and validated for Australia in 2008. Changes in national nutrition recommendations and food availability prompted the redevelopment and revalidation of the UK questionnaire in 2016. However, the Australian questionnaire had not been subsequently updated. Setting: Australia. Participants: Content validity was determined using a sample of academic dietitians in Australia (n 8). Face validity was undertaken with retail employees (n 11) whose highest level of education was secondary school. Ninety-three undergraduate nutrition and engineering students at Queensland University of Technology completed the questionnaire for construct validity, and nineteen students were contacted a week later for test–retest reliability. Results: In the 117-scored questionnaire, nutrition students scored consistently higher in each of the four sections and overall (87 %, M 102, IQR 95, 107) compared with engineering students (77 %, M 82, IQR 76, 87·25, P < 0·01). Internal reliability of the questionnaire was high (α = 0·92) as was test–retest reliability (r s = 0·96, ICC2,1 = 0·99). AUS-R NKQ determined significant differences between individuals with known higher levels of nutrition knowledge and obtained high validity, reliability and consistency within an Australian sample. Conclusions: AUS-R NKQ refined through this research is valid and would be an appropriate questionnaire for assessing the effectiveness of nutrition knowledge-based interventions for public health programmes, clinicians and researchers.

AbstractObjectiveTo validate the general nutrition knowledge questionnaire developed by Parmenter and Wardle (1999) in a Turkish student sample.DesignThe original questionnaire of Parmenter and Wardle (1999) was modified and translated into Turkish. The modified questionnaire was administered to second year undergraduate students. Some students completed the questionnaire twice for the measurement of test–retest reliability. Statistical analysis was performed on the responses to measure the internal reliability, test–retest reliability and construct validity.SettingStudents completed the questionnaire under supervision. The questionnaire was completed at the end of lectures. Retest was carried out two weeks after first administration of the test.SubjectsA total of 195 undergraduate students studying either nutrition and dietetics (n 90) or engineering (n 105) participated in the study. Of these, 125 students completed the questionnaire on two occasions.ResultsOverall internal reliability (Cronbach's α = 0·89) and test–retest reliability (0·86) were high. Significant differences between the scores of the two groups of students indicated that the questionnaire had satisfactory construct validity.ConclusionsThe modified version of the general nutrition knowledge questionnaire can be used as a tool to examine the nutrition knowledge of adults in Turkey. In the next stage of the study, some adjustments need to be made to the items that led to low reliability values so that these items will be more applicable to the eating habits and patterns of Turkish people.

AbstractObjectiveThe present study aimed to develop and validate a nutrition knowledge questionnaire in a sample of French Canadians from the province of Quebec, taking into account dietary guidelines.DesignA thirty-eight-item questionnaire was developed by the research team and evaluated for content validity by an expert panel, and then administered to respondents. Face validity and construct validity were measured in a pre-test. Exploratory factor analysis and covariance structure analysis were performed to verify the structure of the questionnaire and identify problematic items. Internal consistency and test–retest reliability were evaluated through a validation study.SettingOnline survey.SubjectsSix nutrition and psychology experts, fifteen registered dietitians (RD) and 180 lay people participated.ResultsContent validity evaluation resulted in the removal of two items and reformulation of one item. Following face validity, one item was reformulated. Construct validity was found to be adequate, with higher scores for RDv. non-RD (21·5 (sd2·1)v. 15·7 (sd3·0) out of 24,P<0·001). Exploratory factor analysis revealed that the questionnaire contained only one factor. Covariance structure analysis led to removal of sixteen items. Internal consistency for the overall questionnaire was adequate (Cronbach’sα=0·73). Assessment of test–retest reliability resulted in significant associations for the total knowledge score (r=0·59,P<0·001).ConclusionsThis nutrition knowledge questionnaire was found to be a suitable instrument which can be used to measure levels of nutrition knowledge in a Canadian population. It could also serve as a model for the development of similar instruments in other populations.

AbstractObjectiveTo outline key statistical considerations and detailed methodologies for the development and evaluation of a valid and reliable nutrition knowledge questionnaire.DesignLiterature on questionnaire development in a range of fields was reviewed and a set of evidence-based guidelines specific to the creation of a nutrition knowledge questionnaire have been developed. The recommendations describe key qualitative methods and statistical considerations, and include relevant examples from previous papers and existing nutrition knowledge questionnaires. Where details have been omitted for the sake of brevity, the reader has been directed to suitable references.ResultsWe recommend an eight-step methodology for nutrition knowledge questionnaire development as follows: (i) definition of the construct and development of a test plan; (ii) generation of the item pool; (iii) choice of the scoring system and response format; (iv) assessment of content validity; (v) assessment of face validity; (vi) purification of the scale using item analysis, including item characteristics, difficulty and discrimination; (vii) evaluation of the scale including its factor structure and internal reliability, or Rasch analysis, including assessment of dimensionality and internal reliability; and (viii) gathering of data to re-examine the questionnaire’s properties, assess temporal stability and confirm construct validity. Several of these methods have previously been overlooked.ConclusionsThe measurement of nutrition knowledge is an important consideration for individuals working in the nutrition field. Improved methods in the development of nutrition knowledge questionnaires, such as the use of factor analysis or Rasch analysis, will enable more confidence in reported measures of nutrition knowledge.

Test Retest Reliability

Valid and reliable questionnaires are necessary to improve the existence and quality of nutrition information, which determines interventions in low-resource settings, especially among decision makers and change agents. The present study evaluated the internal consistency and test-retest reliability of the data collected among 255 head teachers from schools in Mukono and Wakiso districts in Uganda using a general nutrition knowledge questionnaire (GNKQ) earlier developed. Cronbach alpha (α) was used to determine internal consistency. Pearson's correlation coefficient (r) and intraclass correlation coefficient were used to measure test-retest dependability on scores (ICC2,1). Overall internal consistency on 94 items was α = 0.89 at time one and 0.92 at time two. All items yielded data with a satisfactory internal consistency (α > 0.7). Two domains, Expert advice (ICC = 0.64) and Selecting food (ICC = 0.41), were determined to have insufficient test-retest reliability (r < 0.7 and ICC = 0.7), and their items were removed from the next analyses. The remaining nutrition knowledge topics with adequate test-retest reliability were food groupings (ICC = 0.9), nutrition and sickness (ICC = 0.91), and food fortification (ICC = 0.95). According to the findings, the prototype nutrition knowledge questionnaire had acceptable internal consistency and test-retest reliability. These findings indicate that the previously established questionnaire can be used to assess general nutrition knowledge among head teachers. To boost generalizability, future studies could use the questionnaire on a different group of adults.

Purpose Relational dynamics between patients and staff in forensic settings can be complicated and demanding for both sides. Reflective practice groups (RPGs) bring clinicians together to reflect on these dynamics. To date, evaluation of RPGs has lacked quantitative focus and a suitable quantitative tool. Therefore, a self-report tool was designed. This paper aims to pilot The Relational Aspects of CarE (TRACE) scale with clinicians in a high-secure hospital and investigate its psychometric properties. Design/methodology/approach A multi-professional sample of 80 clinicians were recruited, completing TRACE and attitudes to personality disorder questionnaire (APDQ). Exploratory factor analysis (EFA) determined factor structure and internal consistency of TRACE. A subset was selected to measure test–retest reliability. TRACE was cross-validated against the APDQ. Findings EFA found five factors underlying the 20 TRACE items: “awareness of common responses,” “discussing and normalising feelings;” “utilising feelings,” “wish to care” and “awareness of complicated affects.” This factor structure is complex, but items clustered logically to key areas originally used to generate items. Internal consistency (α = 0.66, 95% confidence interval (CI) = 0.55–0.76) demonstrated borderline acceptability. TRACE demonstrated good test–retest reliability (intra-class correlation = 0.94, 95% CI = 0.78–0.98) and face validity. TRACE indicated a slight negative correlation with APDQ. A larger data set is needed to substantiate these preliminary findings. Practical implications Early indications suggested TRACE was valid and reliable, suitable to measure the effectiveness of reflective practice. Originality/value The TRACE was a distinctive measure that filled a methodological gap in the literature.

Background: The validation of widely used scales facilitates the comparison across international patient samples. Objective: The objective was to translate, culturally adapt and validate the Simple Shoulder Test into Argentinian Spanish. Methods: The Simple Shoulder Test was translated from English into Argentinian Spanish by two independent translators, translated back into English and evaluated for accuracy by an expert committee to correct the possible discrepancies. It was then administered to 50 patients with different shoulder conditions.Psycometric properties were analyzed including internal consistency, measured with Cronbach´s Alpha, test-retest reliability at 15 days with the interclass correlation coefficient. Results: The internal consistency, validation, was an Alpha of 0,808, evaluated as good. The test-retest reliability index as measured by intra-class correlation coefficient (ICC) was 0.835, evaluated as excellent. Conclusion: The Simple Shoulder Test translation and it´s cultural adaptation to Argentinian-Spanish demonstrated adequate internal reliability and validity, ultimately allowing for its use in the comparison with international patient samples.

The aim of the present study is to test the factor structure and reliability of the Experience of Close Relationships-Relationship Structures Scale (ECR-RS) mother, father, romantic partner, close friend forms among Turkish adolescents. In order to test the structure validity of the ECR-RS, exploratory factor analysis is performed on a sample of 214 participants in Study 1, and to further investigate the structure validity, confirmatory factor analysis is performed on a second sample of 286 participants in Study 2. Within the scope of the reliability studies of the ECR-RS, internal reliability and test–retest reliability of the Turkish ECR-RS are also tested. The results of the explanatory and confirmatory factor analysis, Cronbach’s alpha coefficients, and test–retest reliability scores supported the original two-factor structure (attachment avoidance and attachment anxiety) for all forms of the ECR-RS among Turkish adolescents.

There is a paucity of validated mental health measures for assessing psychological well-being among HIV-affected youth. We sought to explore the psychometric properties and validity of the Achenbach Youth Self-Report and Child Posttraumatic Stress Disorder Symptom Scale among orphans and vulnerable children (OVC) living in Lusaka, Zambia. These scales were administered to 210 OVC aged 13 to 17 years via audio computer-assisted self-interview. Confirmatory factor analysis was used to assess scale structure, Cronbach’s alpha for internal consistency, and correlations between scales related to mental or psychosocial health for construct validity. A known-groups validation was conducted using local identifications of youth with and without significant psychosocial problems, and test–retest reliability was assessed. Scales exhibited good internal reliability (α > .80), adequate criterion validity (area under the curve > .70), and moderate test–retest reliability (.62-.68). Findings support the utility of these symptom scales for identifying OVC experiencing significant psychosocial problems in Zambia.

ABSTRACTBackground: This paper reports the development and validation of the Chinese Significant Wish Fulfillment Scale (CSWFS), a new multidimensional scale for assessing the perceived importance and level of fulfillment of wishes of older adults.Methods: Three studies were involved. Study 1 developed a 26-item pool on wish fulfillment through in-depth interviews with 22 older adults. Study 2 reduced the pool to 23 items through validation with a new sample of 315 older adults and examined the internal reliability. Study 3 involved a confirmatory factor analysis (CFA) and examined the test-retest reliability and the convergent validity of the scale with the construct of regret.Results: A five-factor structure model of 23 items was identified through exploratory factor analysis, which accounted for 51.67% of variance. As informed by the CFA in Study 3, a five-factor 22-item model was the best fit. Internal reliability and test-retest reliability was found to be good. Convergent validity was examined through correlation with the construct of future regret. The correlation, though statistically significant, was small.Conclusion: CSWFS demonstrates good psychometric properties, but the construct might be slightly different from that of future regrets. Probably, CSWFS addresses a construct that is under-explored but is of importance to older adults and especially to the Chinese community.
