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.

Development and Validation of a Scale to Measure Violence against Women among Myanmar Migrant Women in Thailand

Introduction: Violence against women (VAW) is a serious human rights violation with significant implications for public health. VAW affects the well-being of women, children, and families. This study aims to develop and validate a scale specifically designed for identifying and assisting migrant women who have experienced violence. Methods: A cross-sectional survey using stratified sampling was conducted among 295 Myanmar migrant women in Thailand. Violence among these women was assessed using self-administered questionnaires with data collection taking 15–20 min per participant between September and December 2023. The construct validity of the Violence against Migrant Women Scale (VAMWS) was confirmed through exploratory factor analysis (EFA) estimated by weighted least squares means and variance with Geomin rotation in Mplus software. Results: The EFA revealed a 13-item scale with a four-factor structure that fit the data exceptionally well, as indicated by the high comparative fit index of 0.99 and low root mean square error of approximation value of 0.02. Communalities ranged from 0.58 to 0.99 and rotated factor correlations between 0.36 and 0.53. The four dimensions were as follows: F1 – physical (4 items, loadings 0.51–0.73), F2 – sexual (2 items, loadings 0.66–0.99), F3 – psychological (3 items, loadings 0.57–0.73), and F4 – economic (3 items, loadings 0.50–0.78). VAMWS had Cronbach’s alpha of 0.90 and corrected item–total correlation values from 0.53 to 0.74. Physical violence, experienced by 50% of respondents, was most common, primarily by spouses, then siblings, acquaintances, employers, parents, and friends. Conclusion: VAMWS is applicable for assessing violence prevalence across multiple sectors, including health care, social services, law enforcement, and future research endeavors.

This study uses an experimental research method because it will look for the effect of certain treatments. The type of research is the Quasi Experiment. The quasi-experimental research design used in this research is the Nonequivalent control group design. In this design there are two groups used, namely the experimental group and the control group. The population used in this research was all class I138students at SD Negeri 040443 Kabanjahe, totaling 40 children, with the sample being classes B1 and B2 determined by purposive sampling. Data collection techniques by conducting observations, questions, and answers (interviews), and taking physical evidence such as photographs (documents), and RPPH. Before being used, the instrument was tested for validity and reliability. Validity testing with the Corrected Item Total Correlation technique and reliability testing with Cronbach Alpha's technique. All calculations use the help of the SPSS program version 18.0 for windows. Furthermore, to meet the requirements of the hypothesis test, normality calculations were carried out with the Kolmogorov-Smirnov test and homogeneity calculations with the Lavene Statistic test on both samples (class B1 and class B2). Data analysis techniques were carried out with descriptive statistics and continued with inferential statistics using the t-test or t-test, with the formula paired sample t-test and a significance value of α = 0.05 (5%). Based on the results of the study, it was concluded that the use of Big Book media in the English learning process on vocabulary proved to have a significant effect on the development of children's English vocabulary in the experimental group in class B1. The level of vocabulary development of children who were given treatment was higher compared to the group of children who were not given treatment, in the experimental group and the control group there was a "quite significant" difference. Based on calculations carried out with the help of the SPSS version 18.0 for Windows program, it is known that the value of t in the SPSS output after the paired samples T-test analysis was -5.315. Where in the t value there is a minus sign (-) which is a sign that there is a difference between the two groups. Therefore, the presence of this minus sign indicates a signal that there is a difference between the two groups (experimental and control).

Polish adaptation, psychometric properties and validation of Physician’s Trust in the Patient Scale (PTPS)

Mutual trust is considered one of the critical aspects of building a successful doctor-patient relationship. Albeit patient trust in physicians has been widely explored by researchers, physician trust in patients remains neglected, which is reflected by the lack of existing tools to assess this construct. Therefore, we aimed to validate and adapt Thom’s Physician’s Trust in the Patient Scale (PTPS) in Polish. We conducted a survey-based study among 307 medical doctors. To determine the factor structure of the scale, both exploratory (EFA) and confirmatory factor analysis (CFA) were performed. The two-factor solution was established for the scale in accordance with the original version. To determine the internal reliability and consistency of the scale, we measured Cronbach’s alpha, corrected-item total correlation, and discrimination indices—all of them obtained very good or excellent values. Estimates of convergent and discriminant validity reached all suggested thresholds. The scale also performed well in theoretical validity. Together, these findings suggest that the psychometric properties of the Polish adaptation and validation of PTPS are satisfactory and that the tool can find practical and scientific applications. We believe that the scale can substantially add to our understanding of building trust-based relationships and rapport between patients and physicians.

The Posterior Shoulder Instability Questionnaire: internal consistency, content and criterion validity, responsiveness, and reliability of a new tool for the assessment of posterior shoulder instability

Posterior shoulder instability (PSI) is an increasingly recognized cause of shoulder dysfunction particularly in young active patients and certain athlete populations. When evaluating the efficacy of treatment for PSI, specific outcome measures for this population are essential. The aim of the current research was to describe the development and evaluation of a patient reported outcome measure (PROM) specific for PSI. A retrospective cohort study design of patients with PSI was used to develop and evaluate the "Posterior Shoulder Instability Questionnaire (PSI-Q)". Items for PSI-Q were generated through an expert focus group and existing questionnaires. Preliminary data analysis identified redundancy of items and resulted in the PSI-Q being refined. The final PSI-Q was evaluated on 128 patients with PSI with a structural lesion requiring surgical intervention. Participants were excluded in the absence of a posterior glenohumeral joint lesion. Internal consistency (Cronbach α and corrected item-total correlation), content validity, criterion validity, responsiveness, and test-retest reliability (intraclass correlation coefficient; ICC) were examined. Content validity, criterion validity and responsiveness were compared with the Melbourne Instability Shoulder Score (MISS) and the Western Ontario Shoulder Index (WOSI). The minimum detectable change score (MDC) was calculated. The Cronbach α for the total scale pre and post-intervention was high (α = 0.97). All five domains (Pain, Instability/Weakness/Stiffness, Function, Occupation and Sport, and Quality of Life and Satisfaction) demonstrated acceptable internal consistency for each subsection and the overall score of the scale (α > 0.70). The corrected-item total correlation for each domain were within an acceptable range. The responsiveness of the PSI-Q questionnaire was excellent (effect size, 2.06; standard response mean, 1.34) and was higher than the MISS and WOSI. There were no relevant floor effects and one ceiling effect. Reliability was excellent (ICC (1,1) = 0.93) and the calculated MDC was 10.9 points. This study designed and validated a questionnaire specific for measuring symptoms and function in people with structural PSI requiring surgery. The PSI-Q demonstrates good measurement properties and provides an MDC that is useful for researchers and clinicians. In structural PSI, the PSI-Q has a higher responsiveness and more accurately reflects a patient's overall perceived shoulder status compared to current patient reported outcomes for shoulder instability. The psychometric properties of the PSI-Q are still to be determined in a non-surgical population.

Psychometric evaluation of Suicide Management Competency Scale for nursing students: A cross-sectional study.

Suicide management skills are essential for nursing students, as they are often the initial healthcare contact for individuals at risk of suicide. Recognising signs of suicidal ideation and behaviour is critical for initiating timely interventions. This study aimed to develop and access the psychometric evaluation of the Suicide Management Competency Scale (SMCS) for nursing students. A first draft of the SMCS was initially developed following literature and focus group, and a scale containing 28 items was constructed. We recruited 216 participants from two nursing schools. Construct validity was evaluated with exploratory factor analysis (EFA). Internal consistency reliability was determined with Cronbach's alpha, and test-retest reliability was examined with intra-class correlation. After four rounds of EFA and item analysis, we reduced the number of items to 16. We deleted 12 items, including 4 items for communalities less than 0.40, 3 items for cross-loading, 3 items for factor loading less than 0.40, and 2 items for low corrected item-total correlation. The final 16-item SMCS resulted in three subscales, which explained 55.813% of the total variance: emotional challenges in suicide risk assessment, delivering suicide interventions, and suicide risk nursing competence and confidence. Cronbach's alpha was 0.854 for the total score and 0.748 to 0.847 for the subscales. The newly developed SMCS was found to have good reliability and validity, suggesting that this scale could be used to evaluate nursing students' perceived competency in managing suicide, which might help cultivate competence in nurses' ability to effectively manage and prevent suicide, thus contributing to saving lives.

Using Discourse Markers to Enhance Students’ Speaking Skills

English proficiency is a desirable performance quality. The aim of this study is to determine the effectiveness of discourse markers in improving English speaking skills. This study employs a quantitative methodology. This study employed a pre-test-posttest group design, The study's demographic and sample consist of Class XI IPA 80 students from the academic year 2023/2024. The researcher employed the snowball sampling method to ascertain the requisite sample size. Prior to conducting the pre and post tests, the researcher assessed the instrument's validity and reliability using SPSS. This was done by examining the scores on the corrected item total correlation, which measures the correlation between item scores and the total item score. The students were designated as Group A (experimental) and Group B (control). Subsequently, students engage in a Pretest to ascertain any disparities among them. The researcher provided discourse markers to both groups; however, only the experimental group employed them, whilst the control group did not. The experimental group will receive treatment including the use of discourse markers. The T test was employed as the data analysis tool. The results indicated that the observed T value was 7.313, and the Sig. value was less than 0.05. Therefore, it can be inferred that the utilisation of discourse markers enables students to enhance their proficiency in English speaking. This research is significant as it can enhance English language acquisition, particularly by highlighting the significance of teachers' role in teaching discourse markers during English language learning.

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.

Bimanual ability for brachial plexus birth injury: a validity and reliability study of the ABILHAND-Kids

Purpose ABILHAND-Kids is a structured parent report that assesses manual ability in activities of daily living in children with cerebral palsy, and also brachial plexus birth injury (BPBI). This study investigated the validity, test-retest reliability, and internal consistency of the ABILHAND-Kids in children with BPBI. Materials and methods The ABILHAND-Kids was administered to parents of 119 children with BPBI between 6 and 15 years for validity and internal consistency, also 92 parents were re-interviewed after two weeks to establish test-retest reliability. Its concurrent validity was examined by correlating scores on the ABILHAND-Kids with Active Movement Scale-Total Score. Results ABILHAND-Kids were strongly correlated with AMS-Total score (p < 0.001, r = 0.87) ABILHAND-Kids test-retest reliability was excellent (ICC: 0.93, %95 CI: 0.90–0.95). The internal consistency for the total score of ABILHAND-Kids was excellent (alpha = 0.94). For 20 items, item-total correlations were adequate (corrected item-total correlations, 0.27–0.85), one item which was “switching on a bedside lamb” had no adequate correlation (corrected item-total correlations, 0.011). The ABILHAND-Kids score showed a statistically significant difference between the Narakas types (p < 0.001). Conclusion The ABILHAND-Kids has excellent reliability and strong validity for measuring manual ability or bimanual performance in activities of daily living in children with BPBI.

Including personal boundaries scale: development and psychometric properties of a measurement for nurses' self-efficacy toward intimate and sexual behavior in dementia care.

Person-centered nursing home care recognizes the intimate and sexual needs of residents with dementia but lacks guidance for nurses to address them while effectively respecting their personal boundaries. The Including Personal Boundaries (IPB) scale was developed to complement clinical and scientific efforts to support both nurse and resident wellbeing. Through a co-creative process, theoretical principles, day-to-day experiences, and expert knowledge were integrated into an initial nineteen-item version of the IPB scale. The pilot sample comprised 297 Dutch (vocational) nurses in dementia nursing care. After Principal Component Analysis, nine items with strong factor loadings (>0.6) were retained. Internal reliability measures supported the item selection, such as high internal consistency (α = 0.866) and adequate corrected item-total correlations (0.532-0.781). The presented IPB scale, a nine-item scale, is a short, robust measure to assess nurses' self-efficacy in their capabilities to include personal boundaries (physical and emotional) when confronted with the intimate and sexual behaviors of residents with dementia. Further validation is recommended. The IPB scale could provide valuable insights for research, clinical practice, and education.

Nonparametric Kernel Smoothing Item Response Theory Analysis of Likert Items

Likert scales are the most common psychometric response scales in the social and behavioral sciences. Likert items are typically used to measure individuals’ attitudes, perceptions, knowledge, and behavioral changes. To analyze the psychometric properties of individual Likert-type items and overall Likert scales, mostly methods based on classical test theory (CTT) are used, including corrected item–total correlations and reliability indices. CTT methods heavily rely on the total scale scores, making it challenging to directly examine the performance of items and response options across varying levels of the trait. In this study, Kernel Smoothing Item Response Theory (KS-IRT) is introduced as a graphical nonparametric IRT approach for the evaluation of Likert items. Unlike parametric IRT models, nonparametric IRT models do not involve strong assumptions regarding the form of item response functions (IRFs). KS-IRT provides graphics for detecting peculiar patterns in items across different levels of a latent trait. Differential item functioning (DIF) can also be examined by applying KS-IRT. Using empirical data, we illustrate the application of KS-IRT to the examination of Likert items on a psychological scale.

Select a winning Lean Six Sigma 4.0 project: Best Worst Method based decision making approach

Manufacturers are adopting Lean Six Sigma4.0 (LSS4.0) to improve their operations. However, poor project selection results in substantial losses. The aim of this study is to provide a framework for LSS4.0 project selection in an industrial context using the Best-Worst-Method (BWM)-based ‘multi-criteria decision making’ (MCDM) technique. First, 25 project selection criteria were pre-selected using a literature review and expert opinions. All criteria were then grouped into six different dimensions, closely related to the LSS4.0 principles, based on expert opinion and similarity with literature findings. To finalize the selection, a rigorous evaluation is undertaken using corrected item-total correlation (CIMTC) and importance index analysis methods, resulting in a final set of 22 project selection criteria, prioritized using BWM. The practical applicability of this method is demonstrated by a case study in a Moroccan manufacturing context. Operational and technical feasibility, strategic orientation, finance and business development emerged as top priorities. This research can help senior managers make informed choices about projects and recognize potential in uncertain scenarios.

Psychometric Properties of the WBIS/M in a Representative Prebariatric Sample: Evidence for an Improved 10-Item Version

Introduction: The Weight Bias Internalization Scale and the Modified Weight Bias Internalization Scale are well-established self-report questionnaires for assessing weight bias internalization, which is widespread among bariatric patients. However, among this group, psychometric properties of the Weight Bias Internalization Scale have only been examined in small samples showing unsatisfactory model fit and have not been explored for the modified questionnaire. Methods: This study psychometrically evaluated and compared the Weight Bias Internalization Scale and Modified Weight Bias Internalization Scale in a large sample of prebariatric patients (N = 825, mean age = 46.75 years, SD = 11.55) regarding item characteristics, model fit to unidimensionality, reliability, construct validity, and measurement invariance. Results: Item 4 of both questionnaires showed low corrected item-total correlations (<0.40) and was therefore removed from the scales. The new 10-item versions showed improved item characteristics, internal consistency, model fit to unidimensionality, and convergent and divergent validity when compared to the 11-item versions. The best psychometric properties were found for the 10-item version of the Modified Weight Bias Internalization Scale. Conclusion: The 10-item version of the Modified Weight Bias Internalization Scale surpasses the other versions studied in all psychometric properties. Therefore, it should be used in prebariatric patients to detect weight bias internalization and provide them with psychological interventions that could improve bariatric surgery outcomes.

Purchases Decision Making Inventory: Measurement Validation in Indonesia

The empirical limitations of the Consumer Styles Inventory (CSI) render the formation of dimensions from this measuring tool-less relevant. Scholars have attempted developing Purchase Decision Making Inventory (PDMI) measuring tool to answer cognitive and emotional processes in decision-making. This research examined the validity of the internal structure of the purchasing decision-making inventory (PDMI) measuring device in the Indonesian context. PDMI has two main dimensions, namely emotional and reasoned. The emotional dimension has five sub-dimensions: impulsivity, indebtedness, negative emotions, frustration, and hedonism. The reasoned dimension has three sub-dimensions: saving, reasoning, and information seeking. The main dimensions explain the differences in cognitive and affective processes that occur in consumers when making decisions. The internal structure of PDMI was evaluated using Confirmatory Factor Analysis (CFA) and reliability analysis. The population of this study was Indonesian people aged 18-25 years (M = 20.3 years, SD = 1.55). The sample in this study was 588. The results of the CFA analysis showed that the results fit the data. The model accuracy indices used are the comparative fit index (CFI), Tucker-Lewis index (TLI), and root mean square error of approximation (RMSEA). The CFI value is 0.932, the TLI value is 0.921, and the RMSEA is 0.046. The results of this research are supported by the reliability results of each sub-dimension and the primary dimension of the PDMI measuring instrument, which has a Cronbach's alpha value ≥ 0.6 with a corrected item-total correlation (CITC) ≥ 0.3 which can be concluded that the PDMI measuring device is valid based on internal structure and reliable evidence sources.

Prosociality of Modernist Islamic Volunteers in Responding to The Semeru Volcano Eruption

Recently, there has been growing interest in the study of community responses to disasters in Indonesia at macro and meso-levels analysis while little has been paid attention to this study at the micro one or individual level. To fill the literature gap, this article aims to describe prosocial behaviors performed by volunteers involved in addressing the Semeru volcano eruption victims in Lumajang Indonesia occurred in 2021. It was a result of descriptive quantitative research involving 202 participants who identified themselves as Muhammadiyah’s volunteers involved in the humanitarian activities in addressing the natural disaster. The data collection of pro-sociality utilized a prosocial behaviors scale including five aspects: honesty, helping, cooperating, caring, and donating. The validity test of the items used corrected item-total correlation that resulted in 34 valid items, and it had a good reliability based on Cronbach’s coefficient alpha test which was 0,953. The result shows that the participants had predominantly at the moderate level of prosocial behaviors which was four-fifths of the participants. Only a small proportion placed at the high pro-sociality, likewise those who were at the low level meaning these two categories were not significant. This finding is expected to enrich literature related to the role of civil society in responding to disasters, especially at the individual level. However, some relevant topics such as relating prosocial acts to other variables need to get attention for future research to result in comprehensive empirical evidence on this issue.
