Validity and reliability of a questionnaire on knowledge, attitude, practice and
perception (KAP2) towards food poisoning and its prevention during dining out
among consumers in Terengganu

Having adequate knowledge, attitude, practice, and realistic perception (KAP2) of food poisoning prevention will minimize the risk of food poisoning while dining out. However, there is no validated KAP2 questionnaire on the prevention of food poisoning during dining out, notably among consumers. Throughout the current research, a validated KAP2 questionnaire on food poisoning and prevention during dining was developed. A crosssectional pilot survey was conducted among 30 selected consumers in Kuala Nerus, Terengganu. Convenience sampling was applied to the recruitment of consumers based on inclusion and exclusion criteria. The KAP2 questionnaire comprised the knowledge section (42 questions), attitude (15 questions), practice (13 questions) and the perception (15 questions). Knowledge questions were analysed using difficulty and discrimination index, while attitude, practice, and perception were analysed by construct validity and reliability analysis. The difficulty index with less than 0.3 is considered as difficult, between 0.30-0.70 as an acceptable value, and more than 0.70 as easy. The discrimination index below than 0.2 is considered poor, between 0.2-0.24 as good, more than 0.35 as excellent items. The construct validity was conducted by referring to the value of Cronbach's alpha, inter-item correlation (˃ 0.30), item-total correlation (˃ 0.30), and Cronbach's alpha if item deleted. The results were found from 42 knowledge items, 29 easy items, ten acceptable items and three difficult questions. The discrimination index revealed that 25 items were poor, 11 items were excellent, three items had a good discrimination index and three items needed to be revised. Based on construct validity, five attitude’s items, three practice’s items and ten perception’s items were removed due to inter-item correlation and item-total correlation value < 0.30. The reliability analysis of the attitude portion was 0.848 which is a good reliability, 0.780 practice, and 0.611 perceptions to be found an acceptable value of reliability. Overall, the developed KAP2 questionnaire is a valid and reliable questionnaire that can serve as an evaluation tool for measuring knowledge, attitudes, practice and perception in the prevention of food poisoning during dining out among consumers.

Simulation Evaluation

Background and objective: Globally, the use of clinical simulation has been incorporated in different nursing programs. It is important to evaluate simulation using reliable and valid instruments. Using the same instrument helps to evaluate simulation under the same criteria both nationally and internationally. The National League of Nursing developed three simulation scales which is widely used in different countries and demonstrates a good reliability and validity. Nevertheless, it is only available in English. The aim of the study was to translate the original NLN simulation evaluation scales into Traditional Chinese and evaluate its psychometric properties.Methods: Beaton and colleague’s (2000) cross-cultural adaptation guidelines was adopted. Cronbach’s alpha coefficient (α) and Corrected item-total correlation was used to determine the internal reliability. Haccoun’s single group technique was used to assess the equivalent of the scale in the original and the translated version. Lastly, Exploratory Factor Analysis (EFA) was used to determine the factor structure and Intra-Class Correlation Coefficient (ICC) to test the stability of translated scale.Results: Nine simulation experts from Hong Kong, Mainland China, Singapore and Taiwan confirmed translation of the NLN scales (EPQ-C, SDS-C, SSCL-C). Cronbach’s alpha of all subscales and overall scales were acceptable (0.72-0.89). The intra-language, inter-language and temporal inter-language cross correlations between the original and translated scales were correlated (p < 0.01). ICC of the translated scales ranges from good to excellent (0.78-0.91). Lastly, EFA also demonstrated the items were theoretically coherent (≥ 0.40) and have the same factor structure as the original English version.Conclusions: Traditional Chinese NLN simulation evaluation scales demonstrated strong validity and reliability.

Today, many organizations have realized an important of pre-development process in order to compete with competitor through drastically introduce new product in the market. In view of that, understanding critical factors that contribute to successful pre-development process implementation is becoming the more important. However, most of past studies were conducted in large organization, very little has been done in small and medium enterprise (SMEs). SMEs have certain limitation in terms of their financial, human, technical, and resources that could hinder their progress towards implementing pre-development process. This paper reviews and analyses CSFs developed by previous authors in order to propose a set of CSFs which were thought to be critical for SMEs. After that the questionnaire developed in this study will be analysis using factors analysis and reliability test in order to examine construct validity and reliability. An initial draft of the questionnaire was developed based on the literature. The questionnaire was pre-tested by academicians and industry practitioners. After that the questionnaire was piloted at 55 food and beverage manufacturing SMEs to check its reliability by using Cronbach’s alpha value. In addition, principle component analysis was carried out to test the construct validity. All the factors in the survey instrument had a Cronbach’s alpha coefficient of more than 0.7 which may be considered satisfactory. Through factor analysis, all KMO values were found above acceptable value of 0.50. All Bartlett’s Test in this analysis was found to be significant. Therefore the instrument is valid and reliable and considered as satisfactory. Nine CSFs, which are believed suitable for SMEs have been proposed in this paper. Through systematic identification and validation, it is hope that the set of CSFs could be used as guides for SMEs to implement pre-development process successfully.

The Impact

Introduction It is required to have validated instruments in health science students that identify unhealthy habits and assess the impact of educational interventions and programs aimed at promoting a healthy lifestyle. Objective To evaluate the validity and reliability of an instrument to measure medical students' lifestyles. Methods A lifestyle questionnaire was developed using the Delphi technique by a group of experts. The final questionnaire was applied to 332 students of the School of Medicine of the Ricardo Palma University in 2017. A preliminary examination was carried out to assess preconditions for construct validity—including the correlation matrix, the Kaiser Meyer Olkin statistic, and the Bartlett sphericity test. Factor analysis was used for construct validity, and the possible resulting factors were extracted through the principal component analysis. Cronbach's alpha coefficient was calculated to assess the instrument reliability. Results In this study, 41.6% of participants were men with a mean age of 20 years (standard deviation = 3). The preconditions for the factor analysis were a Kaiser Meyer Olkin coefficient = 0.773 and a significant Bartlett sphericity test. For the 47 items of the final questionnaire, the factor analysis showed an explained variance of 56.7% with eigenvalues greater than one. Cronbach's alpha was 0.78. The final questionnaire could assume values between -23 to 151 points. Based on a cut point of 71 points, the prevalence of students with an unhealthy lifestyle was 73.6%. Conclusion The developed instrument has acceptable validity and reliability to measure lifestyle in medical students. For external validation, studies in other university populations are suggested.

This study aims to investigate the construct validity and reliability of the checklist for qualitative analysis of the overhand serve in Volleyball. Fifty-five male subjects aged 13-17 years participated in the study. The overhand serve was analyzed using the checklist proposed by Meira Junior (2003), which analyzes the pattern of serve movement in four phases: (I) initial position, (II) ball lifting, (III) ball attacking, and (IV) finalization. Construct validity was analyzed using confirmatory factorial analysis and reliability through the Cronbach’s alpha coefficient. The construct validity was supported by confirmatory factor analysis with the RMSEA results (0.037 [confidence interval 90% = 0.020-0.040]), CFI (0.970) and TLI (0.950) indicating good fit of the model. In relation to reliability, Cronbach’s alpha coefficient was 0.661, being this value considered acceptable. Among the items on the checklist, ball lifting and attacking showed higher factor loadings, 0.69 and 0.99, respectively. In summary, the checklist for the qualitative analysis of the overhand serve of Meira Junior (2003) can be considered a valid and reliable instrument for use in research in the field of Sports Sciences.

Abstract Background Dealing with the spiritual needs of patients has been recognized as one of the principles of holistic care in nursing. Therefore, it is necessary for nurses to deal with the spiritual issues of patients. Also, a valid and reliable scale is needed to measure nurse-provided spiritual care. So the purpose of this study was to determine the validity and reliability of the Persian version of the “Nurse Spiritual Care Therapeutics Scale” in Iranian nurses. Method In a methodological study, English version of the Nurse Spiritual Care Therapeutics Scale was translated into Persian by forward–backward translation procedure. Face validity was assessed by cognitive interview, and content validity was assessed by a panel of experts. In addition, construct validity was assessed by exploratory factor analysis. The participants were 188 nurses working in different adult wards. Reliability was measured using the Cronbach’s alpha and stability reliability was assessed using the internal correlation coefficient (ICC). Results In assessing the construct validity, two factors with eigenvalues greater than 1 were identified, which explained 58.47% of the total variance. Cronbach’s alpha value was 0.932, and ICC was 0.892. Conclusion As a result, the Persian version of the Nurse Spiritual Care Therapeutics Scale shows a good validity and reliability. Therefore, this scale can be used to evaluate spiritual care at the bedside in Iran.
