Development of the Reasoning Ways Scale: Validity and Reliability Study

The aim of this study was to develop a valid and reliable measurement tool to determine the reasoning ways of university students. The study was carried out in two separate stages consisting of the pilot and main application in the 2020-2021 academic year. In the main application, the analysis was made on the data obtained from 378 university students. Exploratory and Confirmatory Factor Analysis was performed for the construct validity of the scale; Average Explained Variance [Average Variance Extracted (AVE)], square root of AVE, Composite Reliability [CR], Maximum Shared Variance [Maximum Squared Variance (MSV)], Average Squared Shared Variance [(Average Shared Square Variance (ASV)] and inter-construct correlations were calculated for convergent and divergent validities. The Cronbach’s alpha internal consistency and CR coefficients were calculated to examine the reliability. The Exploratory and Confirmatory Factor Analysis results showed that the scale had a seven-factor structure (deductive, inductive, analogical, heuristic, algebraic, historical, and verbal) and consisted of 21 items. Convergent and divergent validity of the scale was proved by examining AVE, square root of AVE, CR, MSV, ASV values, and inter-construct correlation coefficients. Cronbach’s alpha and composite reliability coefficients which were calculated for the whole scale and each sub-dimension indicated that the scale was reliable. The results reveal that the Reasoning Ways Scale is a valid and reliable measurement tool.

School Occupational Health and Safety Performance Scale: Validity and Reliability Study for Scale Development

The aim of this study is to develope a scale to evaluate the performance of occupational health and safety practices in schools. The form created for this purpose was presented to experts and the content validity rates of the items were determined in line with the feedback received.The items with a content validity ratio below .80 were excluded from the study. The 49-item trial form was applied via e-mail to 990 teachers working at primary, secondary, and high school levels in public and private schools in İstanbul, affiliated with the Ministry of National Education, and the data obtained were analyzed. With exploratory Factor Analysis (EFA), a two-dimensional structure consisting of 40 items in total revealed "Occupational Health and Safety Training Practices Applied in Schools" and "Occupational Health and Safety Practices Applied in Schools, Managerial Precautions and Precautions". It was determined that the goodness of-fit indices of the model were quite high. Confirmatory Factor Analysis (CFA) also confirmed the EFA results. The obtained correlation coefficients were examined. Item-total score correlation coefficients were between r = .878 and r = .650, and a significant relationship was observed at the p < .01 level. The internal consistency coefficient obtained for the entire scale was .92. There was a significant (p< 0.05) difference between the items and the total score between the 27% lower and 27% upper groups. It was determined that this difference was in favor of the upper 27% group. There was high reliability in the items on the scale, and the items were distinguishable on the basis of the characteristics the scorers of the scale were looking for.

Afghanistan National Depression Screening (ANDs) scale: development and psychometric testing

BackgroundDepression is a complex mental health disorder marked by persistent sadness, hopelessness, and reduced interest in daily activities. The present study developed the Afghanistan National Depression Screening (ANDs) scale and examined its psychometric properties within the Afghan population.MethodsThe study enrolled 1245 Afghan individuals as participants. The items within the ANDs scale were developed through a thorough examination of pre-existing depression scales, expert assessments, and participant interviews. Multiple psychometric evaluations were administered to ensure the reliability and validity of the scale.ResultsAfter review and corrected item-total correlation testing, 15-items exhibiting acceptable corrected item-total correlation coefficients (ranging from 0.315 to 0.647) were retained and further validated through significant factor loadings (ranging from 0.358 to 0.725). Additionally, various properties assessed through classical test theory demonstrated satisfactory results on the 15-item scale. Specifically, measures of reliability such as internal consistency (α = 0.846) and Spearman-Brown coefficient (0.975) were deemed acceptable. Convergent validity was evidenced by strong correlations with established scales, including the DASS-21 (depression subscale, r = 0.854), GHQ-28 (depression subscale, r = 0.693), CES-D 20 (r = 0.922), and PHQ-9 (r = 0.758).ConclusionThe 15-item ANDs scale is developed to assess depression in Afghan populations, showing promise in correlation with established measures like PHQ-9, DASS-21, CESD-20, and GHQ-28. Its potential for identifying depression symptoms warrants further investigation in epidemiological studies and clinical settings, though replication across diverse samples is necessary for generalizability.

PSYCHOMETRIC PROPERTIES OF THE KCCQ–12 IN A EUROPEAN COHORT OF PATIENTS WITH HEART FAILURE

Abstract Background Despite medical advances, patients with heart failure continue to suffer from poor quality of life due to worsening symptoms and functional limitations. Therefore, it is important to understand the multidimensional facets of quality of life in these patients. The Kansas City Cardiomyopathy Questionnaire is a commonly used quality of life assessment tool worldwide. However, However, there is still a lack of knowledge about its psychometric properties. Purpose The aim of this study was to investigate the psychometric properties of the KCCQ–12 and its measurement invariance in a cohort of European patients with heart failure. Methods Participants (n=510, median age=72, IQR=18, 58% males) completed the KCCQ–12 alongside measures of clinical psychosocial severity. A confirmatory factor analysis was used to establish factorial validity; internal consistency was determined using the Omega coefficient and the model–based internal consistency coefficient. Zero–order correlations between the KCCQ–12 scores and clinical and psychosocial measures were performed to test convergent validity. Multigroup confirmatory factor analysis was conducted to test measurement invariance across patients with preserved vs reduced ejection fraction. Results Confirmatory factor analysis confirmed a four–factor solution, with the domains of physical limitations, symptom frequency, quality of life, and social interference. Internal consistency was excellent (Omega coefficients ranging from 0.83 and 0.90, and internal consistency index of 0.94). The KCCQ–12 scores significantly correlated with ejection fraction, New York Heart Association class, quality of life, anxiety, depression, symptom burden, and the KCCQ–23 Overall Summary score, which adequately supported the convergent validity of the KCCQ–12. Measurement invariance was confirmed at the partial scalar and strict level. Conclusions These findings support the validity and reliability of the KCCQ–12, both in patients with reduced and preserved ejection fraction. Hence, this version can be confidently used both in research and clinical practice to measure quality of life of heart failure patients.

Psychometric analysis of the GAD-7 questionnaire in Slovak helping professionals

The GAD-7 is a widely used screening tool for the measurement and diagnosis of symptoms of generalized anxiety disorder. It has been translated and validated across more than 20 cultural contexts. However, no study to date examined its psychometric properties in a Slovak sample, despite the fact that a Slovak translation exists. The purpose of the present study was to test psychometric properties and factor structure of GAD-7 in a general sample of Slovak helping professionals. It was hypothesized that a one-dimensional factor structure would be supported by the data, and that construct validity would be demonstrated. A total of 2239 participants (Mage = 42.20, SD = 14.30) from different helping professions (e.g., psychologists, teachers, special educators, medical doctors, nurses, speech-language pathologists) completed an online survey. A confirmatory factor analysis yielded satisfactory factor loadings and acceptable model fit of the tested one-dimensional model. This evidence was invariant by sex. Internal consistency coefficients indicated good reliability. Significant correlations were found between the GAD-7 and both negative and positive adjustment constructs, thus demonstrating convergent and discriminant validity, respectively. The results of this study add to the evidence on the GAD-7 and its applicability across cultures and support the use of a Slovak translation of the instrument.

Developing a Scale in the junction of Religiousness and Moral Disapproval of Pornography

The development process and validity and reliability studies of the "Moral Disapproval of Pornography Scale" (MDSS) are described in this study. Moral disapproval of pornography use, one of the three components of the Anti-Pornography Problems Associated with Moral Inconsistency (APPM) model, refers to the psychological difficulties created by individuals' pornography use that contradicts their moral beliefs about pornography. This incongruence is shown to have a moderating role between individual’s self-perception of addiction and their psychological well-being. In studies conducted abroad, it is seen that the phenomenon in question is examined with instruments consisting of moral and religious oriented items. These items were reconstructed according to the conditions of our country and turned into a scale that people with different religious beliefs and practices can easily answer. The exploratory factor analysis of the obtained scale was conducted with 634 participants. Subsequently, a confirmatory factor analysis of the scale was performed with a second sample of 580 individuals. The Cronbach's alpha coefficient for internal consistency was calculated as .862, indicating good reliability. The exploratory factor analysis revealed that 71% of the total variance was explained and the items loaded onto a single factor. In the confirmatory factor analysis, acceptable fit indices [χ2 / df = 1.81, RMSEA = .005, AGFI = 0.97, CFI = 0.99, GFI = 0.98, RMR = 0.02] were obtained. In conclusion, the Pornography Moral Disapproval Scale (PMDS) was found to be a valid and reliable measure.

Development and validation of the osteoporosis scale among the system of quality of life instruments for chronic diseases QLICD-OS (V2.0)

BackgroundQuality of life of osteoporosis patients had caused widespread concern, due to high incidence and difficulty to cure. Scale specifics for osteoporosis and suitable for Chinese cultural background lacked. This study aimed to develop an osteoporosis scale in Quality of Life Instruments for Chronic Diseases system, namely QLICD-OS (V2.0).MethodsProcedural decision-making approach of nominal group, focus group and modular approach were adopted. Our scale was developed based on experience of establishing scales at home and abroad. In this study, Quality of life measurements were performed on 127 osteoporosis patients before and after treatment to evaluate the psychometric properties. Validity was evaluated by qualitative analysis, item-domain correlation analysis, multi-scaling analysis and factor analysis; the SF-36 scale was used as criterion to carry out correlation analysis for criterion-related validity. The reliability was evaluated by the internal consistency coefficients Cronbach’s α, test-retest reliability Pearson correlation r. Paired t-tests were performed on data of ​​the scale before and after treatment, with Standardized Response Mean (SRM) being calculated to evaluate the responsiveness.ResultsThe QLICD-OS, composed of a general module (28 items) and an osteoporosis-specific module (14 items), had good content validity. Correlation analysis and factor analysis confirmed the construct, with the item having a strong correlation (most > 0.40) with its own domains/principle components, and a weak correlation (< 0.40) with other domains/principle components. Correlation coefficient between the similar domains of QLICD-OS and SF-36 showed reasonable criterion-related validity, with all coefficients r being greater than 0.40 exception of physical function of SF-36 and physical domain of QLICD-OS (0.24). Internal consistency reliability of QLICD-OS in all domains was greater than 0.7 except the specific module. The test–retest reliability coefficients (Pearson r) in all domains and overall score are higher than 0.80. Score changes after treatment were statistically significant, with SRM ranging from 0.35 to 0.79, indicating that QLICD-OS could be rated as medium responsiveness.ConclusionAs the first osteoporosis-specific quality of life scale developed by the modular approach in China, the QLICD-OS showed good reliability, validity and medium responsiveness, and could be used to measure quality of life in osteoporosis patients.

Adaptation into Turkish of the Social-Emotional Assets and Resiliency Scale for Preschool

The aim in this study was to adapt the Parent and Teacher Form of the Social-Emotional Assets and Resiliency Scale for Preschool, developed by Ravitch (2013) to measure the resilience of preschool children, into Turkish and to test its validity and reliability. The validity and reliability of the Social-Emotional Assets and Resiliency Scale for Preschool were tested with 335 children observed by their parents and 276 children observed by their teachers, selected by random sampling from the population. Confirmatory factor analysis was performed with the software package LISREL v. 8.80. The analysis confirmed the three-factor structure of the scale. When the coherence indices of the scale were examined, it was seen that model data coherence was achieved. The internal consistency coefficient for the Self-Regulation/Social Competence subdimension was .86, for the Understanding/Expressing Emotions subdimension was .83, and for the Empathy/Responsibility subdimension was .83. The scale form consisting of three dimensions and 27 items was designed as a four-point Likert type. Based on the analyses performed, the Social-Emotional Assets and Resiliency Scale for Preschool is a valid and reliable measurement tool within the scope of parent and teacher evaluations of 60- to 72-month-old Turkish children with its three-dimensional and 27-item structure.

Adaptation of the Environmental Worry Index into Turkish: A Validity and Reliability Study on Teacher Candidates

Purpose: In the present research, it was aimed to adapt the Environmental Worry Index (EWI) developed by Oguntayo et al. (2023) into Turkish. Methodology: The study was conducted with the participation of 508 teacher candidates. Exploratory graph analysis (EGA), exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed for the validity studies. The reliability of the measurements collected via the Turkish form of the scale was examined via the Cronbach's alpha internal consistency coefficient. Corrected item total correlations were calculated for item discrimination, and Ferguson Delta was computed to provide a discrimination index for the entire scale. Findings: The EGA outputs and the results of parallel analysis run within the scope of EFA revealed a single-factor structure unlike the two-dimensional original form of the scale. In EFA, the variance explained for the single-factor solution was determined as 45.80% and the factor loadings ranged between .44 and .80. The CFA results showed that the fit indices for the unidimensional model were within the recommended limits and the factor loadings of the items varied between .41 and .71. Cronbach’s alpha coefficient was estimated as .84 and corrected item total correlations ranged between .36 and .62. The Ferguson’s delta statistic, on the other hand, was found to be .95. Highlights: The results obtained provide evidence that the measurements collected through the Turkish form of the EWI have adequate psychometric properties.

Psychometric properties of the Turkish reduced morningness and eveningness questionnaire

ABSTRACT The aim of this study was to examine the psychometric properties of the 5-item Turkish Reduced Morningness-Eveningness Questionnaire (rMEQ) for the first time. The study involved 875 university students in an adaptation and validation study. Participants completed the rMEQ, MEQ, Depression Anxiety Stress Scale-21 (DASS-21), Insomnia Severity Index (ISI), Barratt Impulsiveness Scale Short Form (BIS-SF), and Oxford Happiness Questionnaire Short Form (OHQ-SF). The factor structure, convergent validity, internal consistency, sensitivity, and specificity of the rMEQ were examined. The confirmatory factor analysis showed that the rMEQ had a one-dimensional structure with good fit indices (χ2/df = 2.94, CFI = 0.990, TLI = 0.979, RMSEA = 0.047, and SRMR = 0.019). There was a significantly strong correlation between rMEQ and MEQ. In addition, we found a significantly weak correlation between rMEQ and DASS-21, ISI, BIS-SF, and OHQ-SF. The internal consistency coefficients of rMEQ were Cronbach’s α = 0.706 and McDonald’s ω = 0.740. The sensitivity and specificity of rMEQ were 83.3%–92.7% for morning types and 86.3%–87.3% for evening types. The Turkish rMEQ has adequate psychometric properties and can be used to assess an individual’s chronotype.

Development and validation of the rheumatoid arthritis scale among the system of quality of life instruments for chronic diseases QLICD-RA (V2.0).

Rheumatoid Arthritis is a more serious threatening to people and suitable for QOL measurement. A few specific QOL instruments are available without considering Chinese culture. The present study was aimed to develop and validate the Rheumatoid Arthritis Scale among the System of Quality of Life Instruments for Chronic Diseases (QLICD-RA V2.0). The data collected from 379 patients with RA was used to evaluate the psychometric properties of the scale. The reliability was evaluated by the internal consistency Cronbach's α, test-retest reliability Pearson correlation r and intra-class correlation (ICC). We evaluated the construct validity and criteria-related validity by correlation analysis and structural equation modeling. We compared the differences in scores of QLICD-RA before and after treatment and used the Standard Response Mean (SRM) to assess the responsiveness. The results showed that the internal consistency coefficient Cronbach's α values were greater than 0.70. The correlations r and ICCs were greater than 0.80. The correlation analysis and structural equation modeling confirmed good construct validity and criterion-related validity. The SRM ranges from 0.07 to 0.27 for significant domains/facets. It concluded that QLICD-RA (2.0) is a reliable and valid instrument to measure QOL among patients with RA.

Development of the Blood Stasis Questionnaire for Gynecological Diseases: An Analytical Cross-Sectional Study.

Blood stasis is the slowing or stagnation of blood and can cause metabolic, musculoskeletal, and gynecological diseases. This study developed the Blood Stasis Questionnaire for gynecological disease (BSQ-GD) by extracting clinical indicators related to gynecological diseases using the Blood Stasis Questionnaires I and II (BSQ-I and II, respectively) and analyzed the clinical data of a cross-sectional study. In total, 103 women aged between 25 and 65 years who met gynecological disease criteria were enrolled in this study. Blood stasis scores (BSS) were evaluated using the BSQ-II and categorized into BSS and non-BSS groups. To assess the reliability of BSQ-GD, the internal consistency coefficient was employed using Cronbach's α. Furthermore, correlation analyses were conducted for the clinical symptoms related to gynecological diseases, and the discriminant validity was confirmed by comparing the two groups. The prediction accuracy was determined using logistic regression and the cut-off value of the BSQ-GD was established via the sensitivity and specificity calculations. The BSQ-GD showed satisfactory internal consistency (Cronbach's α coefficient = 0.71) and validity, with significant differences in mean scores between blood stasis (22.30 ± 3.34) and non-blood stasis (14.93 ± 3.49) groups. The cut-off value of the BSQ-GD score was 19 points when the Youden index (73.45) and the concordance probability (0.75) were at their maximum. The area under the receiver operating characteristic curve was approximately 96%, and the sensitivity and specificity of the diagnostic accuracy according to the cut-off value are 80.95% and 92.50%, respectively. The BSQ-GD can be an appropriate instrument to estimate blood stasis in patients with gynecological diseases; its diagnostic sensitivity according to the cut-off value is high.

Psychometric Properties of the Pictorial Scale of Perceived Movement Skill Competence for Young Norwegian Children.

The objective of this study was to examine the psychometric properties of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) for young Norwegian children, a scale that is aligned with skills assessed in the Test of Gross Motor Development- Third Edition. We used convenience sampling to recruit 396 Norwegian-speaking children (7-10-year-olds) who completed the PMSC. A confirmatory factor analysis (CFA) confirmed factorial validity for the proposed three-factor model of the PMSC, encompassing measures of self-perceived ball, locomotor, and active play competence. Internal item consistency coefficients of these sub-scales were acceptable, and subsequent measurement invariant analysis found a gender difference such that boys rated their competence higher than girls in running, jumping forward, hitting a ball (racket), kicking, throwing a ball and rope climbing, while girls rated themselves higher, compared to boys, in galloping and skating/blading. Furthermore, there was a slightly better model fit for boys than for girls. Several items were significantly related to children's age, and the three-factor model exhibited differential age related factor mean differences across older and younger children. Overall, we found the PMSC to have acceptable psychometric properties for confident use in assessing perceived motor competence among 7-10-year-old Norwegian children, though we observed age and gender differences in children's responses that warrant careful interpretation of results and further research investigation.

Turkish adaptation and verification of the incident-reporting attitude scale used for staff in long-term care facilities

Background Determining nurses’ attitudes and behaviors toward error reporting is important in providing safe, high-quality patient care. The current study aimed to test Turkish validity and reliability of the Incident-Reporting Attitude Scale for Staff in Long-Term Care Facilities. Methods This psychometric study was conducted in two stages with 395 nurses and nurse managers in long-term care at a university hospital between May 2021 and January 2022. First, the Turkish adaptation of the scale was performed. The scale's internal consistency was evaluated using Cronbach's alpha and corrected item-total score correlation. Content validity indices were used for content validity, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used for construct validity. Discriminant analysis and internal consistency coefficient were used for reliability analyses. Results The results showed that the Turkish scale adaptation is adequate for language and content equivalence. According to CFA, the scale comprising 31 items and two subscales in the original version showed a significantly good fit in a 26-item and five-factor model. The Cronbach's alpha of the modified scale was 0.92; it was 0.88, 0.94, 0.82, 0.96, and 0.90 for the subscales, respectively. Conclusions The Turkish scale adaptation has consistently shown acceptable psychometric reliability and validity characteristics. It can be used by healthcare services and nursing managers to evaluate nurses’ attitudes toward incident reporting in healthcare facilities providing long-term care.

Examining the Wording Effect: What Are We Measuring?

ABSTRACT In this study, the extent to wording effects impact structure and factor loadings, internal consistency and measurement invariance was outlined. The modified form, which includes items that semantically reversed, explains %21.5 more variance than the original form. Also, reversed items’ factor loadings are higher. As a result of CFA, indexes obtained from modified form are better. Measurement invariance is not ensured at any step, which is a significant finding. These findings point to two forms measure different structures. Despite the quite high internal consistency coefficients obtained from both forms, the reliabilities in the modified form are statistically significantly higher than the original form. Although there are many opinions in the literature on the use of reversed items, this study shed light on the practical implications and psychometric findings.

Designing an observation protocol for professional development providers and mentors working with scientific inquiry‐supported classroom settings

AbstractSeveral observation protocols in different theoretical frameworks and components have been designed and validated by teacher trainers and professional development providers to capture and categorize observational data on the characteristics and level of inquiry in science practices. However, certain constraints limit their wide use, such as the neglect of certain indicators of scientific inquiry, the scoring of just summative goals, or the necessity for extensive observer training. The present study, therefore, aims to propose a tool that assists professional development providers and mentors in diagnosing the closeness of practices to scientific inquiry in the context of various settings, from traditional didactic lectures to scientific inquiry, making it easily operational for self and peer evaluations as well as 360‐degree video feedback. The method concentrated on multiple observations provides supportive evidence about the tool's internal consistency coefficient, the relationship between its components, and the inter‐rater reliability coefficient between multiple scorers. The results highlight that the tool, which includes the components of course structure, course overview, and teacher–student communication, has the potential to contribute to the growing library of observation protocols.

Psychometric properties of the Swedish version of the international outcome inventory – alternative interventions (IOI-AI) – ear surgery (IOI-AIop)

Objective The aims of this study were to adapt the Swedish version of the International Outcome Inventory for Hearing Aids (IOI-HA) to the International Outcome Inventory for Alternative Interventions (IOI-AI) in the context of ear surgery (IOI-AIop) and to test the psychometric properties. Design The validated Swedish questionnaire IOI-HA was adapted to the IOI-AIop by omitting the question about hearing aid use and changing the term “hearing aid” to “surgery” in the remaining items. The validity, component structure and reliability of the IOI-AIop were assessed. Study sample Subjects diagnosed with otosclerosis and undergoing stapedotomy were included in the study (n = 162). Results High mean scores were noted for all items. Ceiling effects were noted, most pronounced for the satisfaction item. Principal component analysis (PCA) yielded a two-component structure explaining 77.5% of the variance. The test-retest reliability measured by intra class correlation coefficient was >0.9, and the internal consistency coefficient measured by Cronbach’s alfa was >0.8. Conclusion The IOI-AIop showed good psychometric properties. However, ceiling effects were observed. The two-component solution was in line with previous factor analyses of the IOI-HA and the IOI-AI. The comprehensive IOI-AIop is recommended as a useful tool to evaluate patient perspectives after ear surgery.

Multidimensional Factors To Measure Quality In Education Institutions

This study aims to assess satisfaction with the quality of education in educational institutions in Algeria and to determine the factors that significantly influence it. The study was based on a survey of inspectors representing the primary control body for educational institutions in Algeria. The questionnaire contained questions based on which the inspectors assessed the quality of education in 1,101 schools (representative sample). A three-point Likert scale was used to evaluate inspectors’ agreement with the statements included in the questionnaire. The questionnaire consists of 7 factors that characterize the quality of the professional development of pedagogical workers, the educational program, textbooks, the educational process, the conditions of school education, the evaluation process, and the effectiveness of the teacher’s work. Correspondence of the data to the normal law of distribution was confirmed with the help of SENWEKS (asymmetry coefficient/skewness coefficient) and KIRTOSIS (variation coefficient or excess) indicators. The reliability of the research tools and the possibility of relying on the questionnaire data were confirmed using Cronbach’s alpha coefficient and validity – using the overall internal consistency coefficient. The internal consistency reliability of the questionnaire was confirmed using Pearson’s linear correlation coefficients between the factors and the total score of the questionnaire. The study proved that the factors of the quality of education, with the highest level of satisfaction expressed by the respondents, were the quality of educational programs (inspectors have a favourable opinion about the educational content, considering it relevant and well structured) and textbooks (inspectors appreciate the clarity and richness of the content of the textbook, emphasizing its essential role in student learning), while they were the least satisfied with the quality of learning conditions (inspectors point to a lack of educational resources, inadequate infrastructure and a large number of students in the classroom). One-sample Student’s t-test (one-sample T-Student Test) was used to identify the factors that have the most significant impact on measuring the quality of education in educational institutions in Algeria. The most important factors were the effectiveness of the teachers, the quality of the curriculum and the quality of the textbooks. The research emphasizes the importance of continuous learning and adequate support for teachers.

Influence of early childhood teachers' psychological contracts on teacher competency: Chain mediating role of job crafting and professional identity

In response to the epochal demand for high-quality development in early childhood education in China, it is imperative and necessary to improve the competency level of early childhood educators. The study aims to investigate the relationship between psychological contracts and teacher competency, and to verify the mediating roles of job crafting and professional identity in the relationship between psychological contracts and teacher competency. This study employed validated measurement scales regarding psychological contracts, teachers' professional identity, job crafting, and teacher competency. Each of these scales has established internal consistency coefficients. Data were collected from 318 early childhood teachers in Sichuan, China. The results highlight the significant impact of psychological contracts on the prediction of teacher competency. It is worth mentioning that the psychological contracts, together with their distinct components such as normative responsibility and development responsibility, have a direct and favorable impact on teacher competency. This implies that developing the psychological contracts might be an effective technique for improving teacher competence. The individual mediation of job crafting and professional identity in the link between psychological contracts and teacher competency has been well-established. However, the combined or chain mediating influence of these factors provides a unique and valuable perspective on the phenomenon of job crafting leading to professional identity, which in turn impacts teacher competency. The study found that psychological contracts have a positive predictive effect on teacher competency, while job crafting and professional identity both have independent and chain mediating roles in the relationship between psychological contracts and teacher competency. Therefore, this study suggests a comprehensive enhancement of the psychological contracts level from aspects such as normative responsibility, interpersonal responsibility, and development responsibility. By stimulating job crafting and professional identity levels in both internal and external environments, we can improve the competency level of early childhood educators.

THE ONLINE DATING INTENSITY SCALE (ODI): VALIDITY AND RELIABILITY STUDY OF TURKISH FORM

The main purpose of the current research is to adapt the Online Dating Intensity Scale (CFAS), developed by Bloom and Taylor (2019) to evaluate the frequency of use of individuals using online dating programs, into Turkish and to conduct reliability and validity studies of the scale. The sample of the research consists of 110 participants who have previously used and/or are currently using any online dating program. Within the scope of the current study, the original form of the scale was translated into Turkish by experts, and the back-translation was made by experts fluent in both languages. For the validity and reliability analyses of the scale, Confirmatory Factor Analysis (CFA) was examined for construct validity, and Cronbach alpha internal consistency coefficient and Composite Reliability (CR) coefficients were examined for reliability analyses. Research findings revealed that the two-factor solution was confirmed in Confirmatory Factor Analysis (CFA). In addition, the Cronbach Alpha Coefficient of the scale is 0.92, and the Composite Reliability (CR) coefficients are 0.86 for the attitudes and 0.71 for intensity sub-dimensions. As a result, it was concluded that the scale has very good psychometric properties and allows a valid and reliable assessment of the intensity of online dating experiences in Turkish culture.
