Development and Validation of the Career Authenticity Scale (CAS).

The self is crucial in career development, and authenticity emerges when individuals live in accordance with their true selves. This true self includes a deep awareness of one's abilities, cognitive, physical, and emotional traits, and unbiased answers to "Who am I?". Given its importance in career development, originality can significantly impact one's professional journey. This study brings a new structure to the field of career counseling with the term career authenticity. Career authenticity is a condition that emerges when individuals manage external influences and make their career choices in accordance with their true selves, thus achieving a work life that contributes to the meaning and purpose of their lives. The Career Authenticity Scale (CAS) was developed and validated in two samples of university students. In Study 1 (n = 402), the CAS was developed, and a structure consisting of 12 items and three dimensions was obtained as a result of exploratory factor analysis. Calculations also included the internal reliability coefficients of the CAS. In Study 2 (n = 322), the structure confirming the factors obtained in the first study was confirmed. Analyses also included convergent and discriminant validity, criterion-related validity, measurement invariance across gender, and item discrimination power of the CAS. The results show that the CAS meets the conditions for convergent and discriminant validity. A positive relationship was detected between the CAS and vocational outcome expectations and career proactive behaviors. The CAS was found to provide measurement invariance at configural, metric, scalar and strict invariance levels according to gender. In conclusion, the CAS was proven to be a valid and reliable measurement tool.

Psychometric evaluation of a COVID-19 health literacy scale applying Rasch analysis

Abstract Background Assessing health literacy in times of the COVID-19 pandemic is vital, since health literacy has been highlighted as a personal resource for managing health information. The HLS-Covid-Q22 questionnaire was developed to measure self-reported COVID-19 health literacy in adults. It has been used and validated, mainly using confirmatory factor analysis, in some studies with different target groups. However, several comprehensive validation studies are needed to ensure the feasibility of a novel measurement tool. In the current study, Rasch analysis has been chosen, as this analysis transforms the categorical responses of the items of the HLS-Covid-Q22 into linear measures. Methods The psychometric properties of the HLS-Covid-Q22 were evaluated in a sample of 2187 German adults applying Rasch analysis. The data is from the German COVID-HL school survey that was generated by employing an online survey in school principals during the third infection wave from March to April 2021 in four federal states. Applying the Partial Credit Model for polytomous data, the responses to the HLS-Covid-Q22 items were transformed into linear measures, unidimensionality was tested and several indices to assess the quality of the measurement tool were computed. Results Unidimensionality of the questionnaire could be confirmed. The rating scale steps worked as intended. Participants used every rating category. Item fit could be verified. High reliability indices were found with a person separation index of 3.41, person reliability of .92, item separation of 20.08 as well as item reliability of 1.0. Conclusions The HLS-Covid-Q22 appeared to be a reliable and valid questionnaire which has not been validated by applying Rasch analysis before. Even though Rasch analysis is already a well-established validation method in other disciplines, it should be used to evaluate other health literacy questionnaires more often to gain comprehensive insights into the intended functioning of measurement tools. Key messages • The HLS-Covid-Q22 questionnaire appears to be a valid and reliable measurement tool. • Rasch analysis is an appropriate method to evaluate the psychometric properties of likert-type rating-scale questionnaires.

Psychometric Properties of Turkish Versions of the Non-Attachment Scale Short Form

This study aimed to examine the psychometric properties of the Non-Attachment Scale Short Form in a Turkish sample. With the participation of 244 adults over 18 years of age, the Short Form of the Nonattachment Scale, the Resilience Scale and the Ontological Addiction Scale were used as data collection tools. Cronbach's alpha and McDonald's omega coefficient were used for the reliability of the Non-Attachment Scale Short Form. According to the results of the analyses, the internal consistency coefficient and McDonald's value were found to be .77 and .78, respectively. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to test the construct validity of the scale. The results of the analyses showed that the model fit and Kaiser-Meyer-Olkin (KMO) values were at an acceptable level. Item factor loadings ranged between .40 and .67 and the scale was found to have a single factor structure. The statistically significant difference between the 27% lower and upper groups among the participants showed that the item discrimination index of the scale was at a good level. According to the correlation findings conducted to test the criterion validity of the scale, non-attachment was found to have positive significant relationships with resilience (r = .60) and negative significant relationships with ontological dependence (r = -.39). As a result, adaptation of the Short Form of the Non-Attachment Scale can be said to be a valid and reliable measurement tool.

Evaluation of the psychometric properties of the Turkish version of the Skin-to-Skin Contact Scale for nurses.

Skin-to-skin contact is the practice with the highest level of evidence that increases the growth, development, and healing rate of the newborn. Neonatal nurses are also the best practitioners of skin-to-skin contact. This study examined the psychometric properties of the Turkish version of the Skin-to-Skin Contact Scale for nurses. This descriptive, correlational, and cross-sectional study was carried out with 226 neonatal and pediatric nurses between July 2022 and July 2023. The data were collected using an online questionnaire, including a descriptive information form and a skin-to-skin contact scale for nurses. Data were analyzed by explanatory and confirmatory factor analysis, Cronbach's alpha, and item-total score analysis. It was determined that the scale consisted of 20 items and four sub-dimensions and that those four sub-dimensions explained 53.01% of the total variance. All factor loads were higher than 0.30 in the explanatory and confirmatory factor analyses. All the fit indices were higher than 0.80, and the Root Mean Square Error of Approximation (RMSEA) was less than 0.080 in the confirmatory factor analysis. Cronbach's alpha was determined to be 0.89 for the total scale and greater than 0.70 for all sub-dimensions. The Skin-to-Skin Contact Scale for nurses was determined to be a valid and reliable measurement tool for Turkish nurses. It is recommended that the scale be used regularly in clinics to determine nurses' attitudes towards skin-to-skin contact.

Turkish adaptation of the fear of cancer scale: validity, measurement invariance and reliability study.

The aim of this study was to evaluate the Turkish cultural and psychometric properties of the cancer fear scale developed by Feng et al. This methodological study was conducted between January and April 2024 with students from a university in eastern Turkey. Data were collected from two different sample groups (sample 1:350, sample 2:245). Personal information form and cancer fear scale were used. In the adaptation process of the scale, language validity, content validity, construct validity, and reliability were examined. Exploratory factor analysis, confirmatory factor analysis, measurement invariance and convergent-divergent validity were used to determine construct validity. Cronbach alpha internal consistency coefficient, test-retest and corrected item-total correlation were used for reliability. According to the results of exploratory factor analysis, it was determined that the fear of cancer scale had a two-factor structure with factor loadings between 0.58 and 0.70. As a result of the confirmatory factor analysis performed on the two-factor structure of the fear of cancer scale, it was determined that the model goodness-of-fit indices were acceptable and had an excellent fit. It has been determined that measurement invariance findings across genders support configural, metric and scalar invariance. The Cronbach alpha internal consistency coefficient of the fear of cancer scale was 0.93, and the corrected item total correlation values were between 0.45 and 0.73. The Turkish version of the fear of cancer scale was found to be a valid and reliable measurement tool.

Theoretical development and validation of asphalt concrete density measurement using non-contact interdigital coplanar capacitive sensor

Asphalt concrete (AC) density serves as a critical criterion for quality control and quality assurance in asphalt pavement construction. Current non-destructive testing (NDT) approaches have shown potential for AC density measurement, but they present disadvantages such as inefficiency and unstable accuracy. This paper developed a novel NDT approach for AC density measurement based on non-contact interdigital coplanar capacitive sensor (ICCS). The feasibility of this approach was evaluated through both numerical and experimental validations. Firstly, the theoretical model of non-contact ICCS for AC density measurement was established based on conformal mapping technique, partial capacitance technique, and dielectric mixing model. Secondly, numerical simulations were performed to validate the developed theoretical model under two scenarios. Thirdly, laboratory experiments were conducted to measure capacitance data and predict density for three common types of ACs. Finally, the error of non-contact ICCS was discussed and compared with that of other NDT instruments. The results indicated that the developed theoretical model could establish the relationship between AC density and capacitance value, which provided the basis for AC density measurement using non-contact ICCS. It was also observed that the capacitance data obtained by the proposed model closely matched those computed by numerical simulations. The maximum errors between theoretical and numerical data were 4.10% and 1.08% for two cases respectively, which proved the feasibility of the theoretical model. Furthermore, experimental results indicated that the capacitance value of AC specimens increased by about 1 pF as the rolling time increases due to a decrease in the volume of air in AC, which reaffirms the validity of AC density measurement using non-contact ICCS. Additionally, the non-contact ICCS demonstrated excellent accuracy with a maximum error of 6.69%, which is comparable to the current mainstream NDT approaches. And it has the advantages of lower cost, simpler data processing and higher efficiency. The findings of this paper offer a new and reliable method and tool for non-destructive and large-scale AC density measurement.

Sustainability Communication in Higher Education Institutions: Scale Development and Validation Study

This article aims to develop and validate the Sustainability Communication Scale in higher education institutions. An eight-step process proposed by DeVellis (2022) was applied to develop the scale, which consists of 32 items capable of measuring the level of sustainability communication in Turkish universities. A total of 1291 participants, comprising 109 academics and 1182 students, participated in the study. Expert opinion analysis, KMO and Barlett tests, exploratory and confirmatory factor analyses, Cronbach's alpha, composite reliability, and partial correlation analyses were all used to check the scale's validity and reliability. According to the results of the exploratory factor analysis using the principal components method, the scale consists of 4 factors: environmental sustainability communication, social sustainability communication, economic sustainability communication, and sustainability of communication. The general structure and measurement of the scale have been validated by confirmatory factor analysis. The internal consistency coefficient found using Cronbach's alpha was .769; internal consistency coefficients found using composite reliability were .875(F1), .888 (F2), .866(F3), .882(F4). The findings indicate that the scale is a valid and reliable measurement tool.

Adaptation of the Food Literacy (FOODLIT) Tool for Turkish Adults: A Validity and Reliability Study.

Food literacy is associated with sustainable food systems and encourages individuals to adopt healthy eating habits. However, there is no validated method that can be used to measure food literacy related to sustainable food systems of Turkish adults. This research aimed to assess the validity and reliability of the Turkish adaptation of the "Food Literacy (FOODLIT) Tool" for Turkish adults. The study involved 328 people aged 19 to 58 years. The FOODLIT-Tool is a five-point Likert-type scale consisting of 24 items and five factors ("culinary competencies", "production and quality", "selection and planning", "environmentally safe" and "origin"). The Cronbach's alpha coefficient was applied to assess internal consistency reliability, showing an excellent scale coefficient of 0.927. The model was evaluated with a confirmatory factor analysis (CFA). The findings of the CFA suggested that the fit indices were acceptable (χ2/df = 1.257, comparative fit index: 0.991, goodness-of-fit index: 0.977, normed fit index: 0.990 and root mean error of approximation: 0.028). Furthermore, there was a positive relationship between the FOODLIT-Tool score and the "Sustainable and Healthy Eating Behaviors Scale" (SHEB) score (r = 0.518, p < 0.001). Our study shows that the Turkish version of the FOODLIT-Tool integrated with sustainable food systems is a valid and reliable measurement tool for assessing the food literacy of Turkish adults.

Adaptation of the health literacy survey19-Europe-Q12 into Turkish culture: A psychometric study.

Conclusion: The 21-item Turkish version of CCFNPS was found to be a valid and reliable scale for measuring the competencies acquired by students after their first clinical training.

Validation of factor structures of the Drinking Motives Questionnaire among the Czech young and adult general population

BackgroundAlcohol use is one of the leading public health concerns in the Czech Republic. Drinking motives play a vital role in both initiation and subsequent alcohol use. A revised version of the self-report Drinking Motives Questionnaire (DMQ-R) has been proposed to assess these motives. The present study aims to validate the DMQ-R in the Czech general population.MethodsA total sample of 1,784 Czech participants completed a national survey. For the analysis, only a sub-sample of the past 12 months alcohol users was used: N = 1,123; 52.8% male; mean (SD) age = 40.2 (13.3). Drinking motives were assessed by the adopted Czech version of the DMQ-R. Both confirmatory (CFA) and exploratory factor analysis (EFA) were conducted to examine the factorial structure of the instrument. The age of the participant was additionally considered in the analysis (15–24 years as opposed to 25–64 years).ResultsThe CFA supported the four-factor model in the 25–64 age group. The analysis supported the construct validity of the Social, Conformity, and Coping factors. The Enhancement factor retained only two items and was found to refer more to a domain of ‘Pleasant Feeling’. For the 15–24 age group, the hypothesised four-factor structure was not corroborated.ConclusionsThe Czech version of the DMQ-R was found to be a reliable measurement tool of the Social, Conformity, and Coping motives. Future research should investigate the dimensionality of the instrument items presumed to correspond to the Enhancement motives. This should be conducted particularly among adolescents and young adults aged 15–24 years, where administering the DMQ-R with a large enough sample is also needed.
