Satisfactory Reliability Research Articles

Validation of the Maslach Burnout Inventory-General Survey 9-item short version: psychometric properties and measurement invariance across age, gender, and continent.

The Maslach Burnout Inventory-General Survey (MBI-GS) stands as the preeminent tool for assessing burnout across various professions. Although the MBI-GS9 emerged as a derivative of the MBI-GS and has seen extensive use over several years, a comprehensive examination of its psychometric properties has yet to be undertaken. This study followed the Standards for Educational and Psychological Testing guidelines to validate the MBI-GS9. Employing a combined approach of classical test theory and item response theory, particularly Rasch analysis, within an integrated framework, the study analyzed data from 16,132 participants gathered between 2005 and 2015 by the Centre for Organizational Research at Acadia University. The findings revealed that the MBI-GS9 exhibited satisfactory reliability and validity akin to its predecessor, the MBI-GS. Across its three dimensions, Cronbach's α and omega coefficients ranged from 0.84 to 0.91. Notably, the MBI-GS9 displayed no floor/ceiling effects and demonstrated good item fit, ordered threshold, acceptable person and item separation and reliability, clear item difficulty hierarchy, and a well-distributed item threshold. However, the results suggested a recommended minimum sample size of 350 to mitigate potential information loss when employing the MBI-GS9. Beyond this threshold, the observed mean difference between the MBI-GS and MBI-GS9 held minimal practical significance. Furthermore, measurement equivalence tests indicated that the MBI-GS9 maintained an equivalent three-factor structure and factor loadings across various gender, age, and continent groups, albeit with inequivalent latent values across continents. In sum, the MBI-GS9 emerges as a reliable and valid alternative to the MBI-GS, particularly when utilized within large, diverse samples across different age and gender demographics. However, to address potential information loss, a substantial sample size is recommended when employing the MBI-GS9. In addition, for cross-cultural comparisons, it is imperative to initially assess equivalence across different language versions at both the item and scale levels.

Phonological assessment for Greek (PAel) test: Reliability and validity in 4-to 6-year-old preschool children

ABSTRACT Single-word phonological tests are widely used for detecting children at risk for Speech Sound Disorders (SSDs). However, specific conceptual and operational criteria should be evaluated to ensure that these assessments are valid and reliable and can serve as diagnostic tools. The current study aimed to investigate the validity and reliability of the screener of a phonological Greek instrument, named the Phonological Assessment for Greek (PAel) comparing the phonological performance of typically developing (TD) children and children with SSDs, aged 4 to 6 years. The participants were 20 TD children and 40 children with SSDs. All participants completed the screener of PAel, the 70-word list of the standardised Test of Phonetic and Phonological Development (TPPD), and a language test, namely the Action Picture Test. Participants who scored below the 25th percentile on the language test were excluded. Phonological analysis revealed that PAel has high content validity. The participants who had received a diagnosis of SSDs presented restricted consonant and cluster inventories and significantly lower whole-word match levels in comparison to their TD peers. The overall Spearman’s correlation coefficients between PAel and TPPD were 0.611 for TD children (p < 0.001) and 0.875 for children with SSDs (p < 0.001), indicating good criterion validity. The tool demonstrated strong test-retest reliability and inter-rater reliability with Spearman values exceeding 0.85, and Intra-class correlation coefficients over 0.90. Overall, the results suggest that PAel has satisfactory reliability and validity and can be used as an assessment tool to detect children at risk for SSDs.

807 Reliability of Simulation-Based Assessment of Surgical Technical Skills

Abstract Aim To examine the reliability of surgical trainees’ assessment data from a structured simulation training and assessment programme. Method The General Surgical Skills Programme is a simulation-based surgical training programme integrated within the clinical training pathway for surgical trainees across London. It is tailored to each trainee’s level of training and subspecialty. The ‘Junior’ pathway involves nine training sessions and one assessment session performing three procedures (Inguinal hernia [IH], laparoscopic cholecystectomy [LC] and small bowel anastomoses [SBA]). Within the scope of the Programme, skills assessment data collection was initiated in 2012. Data collected includes demographics and training data (grade/subspecialty/case numbers). Each procedure is assessed by two consultant surgeons using two procedure specific assessment tools, a visual analogue scale (VAS) and competency assessment tool (CAT). Reliability analyses were performed using SPSS for ‘Junior’ data over a four-year period. Results In total, 355 surgical trainees (Male = 199, Female = 154, Missing = 2) were assessed from 2014 to 2017 (2014 n=105; 2015 n=92; 2016 n=89; 2017 n=69). Both assessment tools showed satisfactory inter-item reliability (IH-CAT α=.794-.903, LC-CAT α=.837–910, IH-VAS α=.851-.991, LC-VAS α=.831-.986, SBA-VAS α=.778-.984). Inter-rater reliability, ICC (1,2), was good to poor across all tools. (IH-CAT .345-.510, IH-VAS .243-.600, LC-CAT .271-.766, LC-VAS .157-.678, SBA-VAS .225-.278). Conclusions The assessment tools used within the Programme both demonstrate satisfactory inter-item reliability. Inter-rater reliability is variable, highlighting a potential utility for assessor training within the Programme.

Reliability of the Croatian Version of Motivation Scale for Free Time

Aim: The Motivation scale for free time was developed to measure motivation for activity of population in their free time. The aim of this study was to determine test-retest reliability of Croatian version of Motivation scale for free time on students. Subjects and Methods: The sample was consisted of 97 students of Karlovac University of Applied Sciences 64 men and 33 women). Study was conducted on two occasions and there were 137 students in first measurement and 97 students in second. The response rate to the second measurement was 70,8 %. Statistical data analysis was performed with the software package SPSS 23.0. The normality of the distribution was checked by the Kolmogorov - Smirnov test to justify the use of parametric procedures. The asymmetry coefficient ranged from +/- 3, and the flattening coefficient from +/- 10, and the distribution is considered normal, so the use of parametric procedures is allowed. The validity was checked in the form of correlations of individual particles with the total result in both measurements. Results: The validity in both measurements proved to be statistically significant. In the first measurement, the correlation range of each particle with the total score on the scale ranged between 0.4 to 0.74, which was statistically significant at a risk level of less than 1 %. In the second measurement, the correlation range of each particle with the total score on the scale ranged between 0.31 to 0.73, which was statistically significant at a risk level of less than 1 %. Conclusion: The results showed satisfactory reliability of Croatian version of motivation scale for free time on students.

Psychometric Features of the Arabic Version of the Children's Communication Checklist (CCC2).

The Children's Communication Checklist-Second Edition (CCC-2) uniquely assesses overlooked communication elements such as pragmatics and context use, which are rarely addressed by conventional language assessments. This study focuses on the psychometric assessment of the CCC-2's Arabic version, tailored to evaluate communication challenges in Arabic-speaking children. This study aims to validate the Arabic version of CCC-2 by testing its reliability and validity specifically for three higher-order constructs: Specific Language Impairment (SLI), Social Communication Disorder (SCD), and Impaired Behaviour within the Arabic-speaking population. A total of 121 participants in Saudi Arabia, showcasing diverse age and gender distributions, participated in the validation process. The study employed a Reflective-Reflective Higher-Order Construct (R-R HOC) model using partial least squares-structural equation modeling (PLS-SEM) to ensure content validity and cross-cultural adaptation of the translated items. Metrics such as Cronbach's alpha for reliability and Average Variance Extracted (AVE) for convergent validity were specifically examined. The study confirmed the reliability and validity of the Arabic CCC-2, demonstrating robust psychometric properties, with Cronbach's alpha and AVE scores indicating satisfactory reliability and convergent validity across constructs. Structural model evaluation further supported the strong interrelations among the constructs of SLI, SCD, and Impaired Behaviour. The results substantiate the Arabic CCC-2 as a reliable and valid tool for assessing communication challenges in Arabic-speaking children, particularly for diagnosing SLI, SCD, and Impaired Behaviour. The validated Arabic CCC-2 has significant potential for application in clinical and educational settings and suggests directions for future research to explore its utility further in diverse clinical populations.

A validity and reliability evaluation of fear of progression questionnaire in Iranian breast cancer patients: A methodological study.

Recognizing the ability to adapt coping mechanisms in response to the unique issues present in various Iranian societies underscores the importance of considering culture and religion when interacting with diverse groups of individuals. The objective of this study was to assess the reliability and validity of the fear of progression questionnaire-short form (FoP-Q-SF) in Iranian breast cancer patients. In this methodological cross-sectional research design, 400 Iranian breast cancer patients completed the FoP-Q-SF in 2023. We assessed the characteristics, content, and both exploratory and confirmatory construct validity of the measures. To evaluate the reliability and construct validity of the FoP-Q-SF, we calculated Cronbach's α, McDonald's omega, and the Intraclass Correlation Coefficient. The average age of the patients was 49.18 (standard deviation = 16.14) years. The results of exploratory factor analysis revealed that a single-factor structure, specifically the self-efficacy scale, accounted for 65.045% of the total variance. The findings from the confirmatory factor analysis indicated a satisfactory model fit. The reliability analysis indicated that the internal consistency and stability of the measures were acceptable. The short Persian version of the FoP-Q-SF exhibits satisfactory validity and reliability. Thus, we recommend using this questionnaire to assess the fear of disease progression among breast cancer patients in Iran.

Development and Testing of the Cyber Malevolent Creativity Behavior Scale

ABSTRACTIn the current research, we developed and tested a Cyber Malevolent Creativity Behavior Scale (CMCBS), which contains 11 items in three dimensions and aims to measure the degree of individuals' cyber malevolent creativity through malevolent creative behaviors in their lives. The results revealed satisfactory reliability with Cronbach's α coefficient of 0.749 for the overall scale. Specifically, the calculated values were 0.681 for cybershaming, 0.799 for technology abuse, and 0.644 for information manipulation. Data were collected utilizing an online survey (N = 988) in the form of a questionnaire. Using exploratory factor analysis and confirmatory factor analysis, the questionnaire's latent structure and contribution of relevant correlates for explaining cyber malevolent creativity were examined. The CMCBS was significantly and positively correlated with the Malevolent Creativity Behavior Scale, Buss–Perry Aggression Questionnaire, and the Cyberbullying Inventory. This, along with the adequate psychometric properties uncovered here, indicates that it is a useful tool for research on cyber malevolent creativity.

Development of the Indonesian Version of the Object-Spatial Imagery and Verbal Questionnaire (IDN-OSIVQ)

Developing the Indonesian Version of the Object-Spatial Imagery and Verbal Questionnaire (IDN-OSIVQ) aims to create a culturally adapted and validated instrument for assessing object-spatial imagery abilities in the Indonesian population. The research utilized a developmental method to test the instrument's reliability and validity through rigorous adaptation procedures, including translation, back-translation, expert review, and pilot testing. Data from 153 students were analyzed to establish the internal consistency, construct validity, and factor structure of the IDN-OSIVQ. Results showed that the IDN-OSIVQ scales had satisfactory internal reliability, with principal component analysis confirming distinct and coherent factors. Object imagery had the highest average score (3.6662), while spatial imagery had the lowest (3.1765). Criterion validity was established as participants' ratings correlated favorably with corresponding tasks. Gender differences were observed: men scored higher on spatial imagery and women on object imagery, yet these differences did not overshadow the strong associations between cognitive style ratings and objective measures. The cultural adaptation process ensured the questionnaire's relevance and comprehensibility, enhancing its applicability. The findings support the IDN-OSIVQ as a reliable and valid tool, suggesting future research should involve more diverse age groups.

Psychometric Properties and Measurement Invariance of the Awareness of Age-Related Change Short Form in Older Adult Samples From Taiwan and Germany.

This study examined the psychometric properties and measurement invariance of the 10-item Awareness of Age-Related Change Short Form (AARC-SF) questionnaire in a Chinese-speaking sample of older adults in Taiwan. Data from 292 participants (Mage = 77.64 years) in the Healthy Aging Longitudinal Study in Taiwan cohort were used for Study 1, whereas data from young-old adult samples in Germany were used for Study 2. Study 1 showed that the AARC-SF had satisfactory reliability and validity for assessing adults' AARC in Taiwan. Analyses confirmed the 2-factor structure of AARC-gains and AARC-losses. Study 2 demonstrated strong measurement invariance across men and women, whereas direct comparisons of the item scores between young-old adults and old-old adults need to be made with caution. Noninvariance of loadings indicated that certain items were more closely linked to AARC-gains and AARC-losses in Taiwan than in Germany. Noninvariance of intercepts suggested potential biases in comparing item scores between Taiwanese and German older adults. The AARC-SF emerged as a reliable and valid instrument for capturing positive and negative subjective aging experiences among Taiwanese older adults. However, it is noteworthy that some items on the AARC-SF may solicit different responses from individuals of different ages and different countries of origin, requiring caution with age group and cross-cultural comparisons.

Too much time or not enough? An observational study of teacher wait time after questions in case-based seminars

BackgroundWe define teacher wait time (TWT) as a pause between a teacher question and the following response given by a student. TWT is valuable because it gives students time to activate prior knowledge and reflect on possible answers to teacher questions. We seek to gain initial insights into the phenomenon of TWT in medical education and give commensurate recommendations to clinical teachers.MethodsWe observed n = 719 teacher questions followed by wait time. These were video-recorded in 29 case-based seminars in undergraduate medical education in the areas of surgery and internal medicine. The seminars were taught by 19 different clinical teachers. The videos were coded with satisfactory reliability. Time-to-event data analysis was used to explore TWT overall and independently of question types.ResultsIn our sample of case-based seminars, about 10% of all teacher questions were followed by TWT. While the median duration of TWT was 4.41 s, we observed large variation between different teachers (median between 2.88 and 10.96 s). Based on our results, we recommend that clinical teachers wait for at least five, but not longer than 10–12 s after initial questions. For follow-up and reproduction questions, we recommend shorter wait times of 5–8 s.ConclusionsThe present study provides insights into the frequency and duration of TWT and its dependence on prior questions in case-based seminars. Our results provide clinical teachers with guidance on how to use TWT as an easily accessible tool that gives students time to reflect on and respond to teacher questions.

Validating the caregiving experiences questionnaire (CEQ) in a Turkish setting: Understanding attachment and parental care in diverse contexts

Despite the universal significance of secure attachments, differences exist in parental responses to children’s signals of need across cultures. While much research has focused on Western countries, there is a growing recognition of the need to explore cultural variations in parental ideologies and caregiving practices. However, limited assessment tools exist for evaluating caregiving experiences, particularly in non-Western contexts. This present design study aims to explore the Turkish validity of the Caregiving Experiences Questionnaire (CEQ), specifically tailored to assess the self-reported caregiving experiences of parents with young children within the attachment system. The Turkish-CEQ was administered to 339 Turkish mothers with children attending preschools. Confirmatory Factor Analysis was employed to assess the congruence of the Turkish data. The results showed that the CEQ is a relevant construct in Turkish culture. The CEQ successfully adapted to Turkish, resulting in a questionnaire comprising 34 items organized into four factors namely maintaining warm parental bond, suffering from separation concerns, struggling with parenting challenges, and imposing emotional parentification on the child. The internal consistency of each factor demonstrates satisfactory reliability, with Cronbach Alpha coefficients ranging between 0.71 and 0.80. Finally, we assessed the criterion validity of the CEQ by examining its relationships with the Parental Burnout Assessment and Parenting Stress Scale. The results support the criterion validity of the Turkish-CEQ. The study provides Turkish researchers with a new instrument for assessing caregiving experiences and paves the way for future cross-cultural studies on caregiving experiences among parents from diverse backgrounds in Turkey.

Psychometric adaptation of the Spanish version of the Brief Pittsburgh Sleep Quality Index in adolescents.

Good sleep quality is essential for adolescent health, yet sleep difficulties persist in this age group. The 6-item Brief Pittsburgh Sleep Quality Index (B-PSQI) was recently developed to improve sleep quality assessment, however, its validity in adolescents remains unexplored. This study examined the B-PSQI's psychometric properties in Spanish adolescents and adapted the scoring method to age-specific sleep recommendations. A cross-sectional study involving 1,065 adolescents (15-17 years; 56.8% female) was conducted in public high schools. Sleep quality was measured using the B-PSQI, the Insomnia Severity Index (ISI), the short Patient-Reported Outcomes Measurement Information System (PROMIS), and the Epworth Sleepiness Scale (ESS). Additionally, depression and anxiety were assessed using the Depression, Anxiety, and Stress Scales. Reliability, validity, and measurement invariance were analyzed. The B-PSQI global scores were 4.5 (SD = 1.9) for the original scoring method and 5.4 (SD = 2.8) for the age-adjusted. The age-adjusted B-PSQI showed satisfactory reliability (ω = 0.84) and concurrent, convergent, and discriminant validity (ISI rS = 0.67; PROMIS rS = 0.71; anxiety rS = 0.40; depression rS = 0.42; ESS rS = 0.29). Adequacy for one-factor structure (χ2(4) = 53.9; CFI = 0.97; TLI = 0.92; RMSEA = 0.108; SRMR = 0.05) and invariance across sexes were supported. Both B-PSQI scoring methods showed similar psychometric properties, but the original yielded a higher percentage of poor sleepers (43.1%; cutoff ≥5) than the age-adjusted version (41.9%; cutoff ≥6). Findings suggest that the B-PSQI is a valid and reliable measure to assess adolescent sleep quality. Its scoring can be adjusted to provide age-specific criteria for good sleep. The B-PSQI has potential utility for screening sleep problems and facilitating overall health promotion in adolescents.

Leadership for quality 4.0: development and validation of a multidimensional measure

Successful implementation of Quality 4.0 (Q4.0) requires leadership, but the understanding of such leadership among scholars and practitioners is insufficient. The purpose of this paper is to explore a leadership scale to provide insights. This study develops the scale via 3 independent samples of quality personnel according to Hinkin's recommended scale development process. Exploratory factor analysis sheds light on the tri-dimensional structure of the scale, which comprises task-oriented, change-oriented, and relations-oriented behaviours. The results are affirmed by confirmatory factor analysis, which also demonstrates satisfactory reliability and construct validity. To further explore the predictive validity of leadership and delve deeper into its mechanics, based on the Job Demands-Resources (JD-R) model, this study identifies connectivity and challenge stressors as keys to the ‘Black Box’ of the relationship between leadership and thriving at work. Structural equation modelling suggests that leadership has a positive influence on thriving at work, connectivity, and challenge stressors. Connectivity and challenge stressors mediate the relationship between leadership and thriving at work. The Q4.0 leadership scale can be used as a guideline for organisations embracing Q4.0 to select and appoint managers, as well as for quality leaders to evaluate and improve themselves.

Construction of Cyan Blue Fluorescence Probe based on Nitrogen-Doped Carbon Dots for Detecting Nitrite Ion in Ham Sausage.

Nitrite ion is one of the materials widely used in human life, and the accurate, sensitive and stable detection of nitrite ions is of great significance to people's healthy life. In this study, nitrogen-doped fluorescent carbon dots (N-CDs) for detecting nitrite salt solutions were prepared using citric acid monohydrate and Chrysoidin as precursors through a one-pot hydrothermal method. Under the condition of pH = 3, a noticeable quenching phenomenon occurred in the carbon dot solution with the increase in nitrite ion concentration. This quenching effect might be attributed to the diazonium effect. N-CDs have been successfully used as fluorescence probes for NO2- detection. NO2- can effectively quench the fluorescence intensity of N-CDs, providing a linear response to fluorescence quenching efficiency with respect to NO2- concentration within the range of 0-10µM and 10-30µM, and a detection limit of 52nM, showing high sensitivity. In addition, the probe was applied to the determination of NO2- in ham sausage samples with a detection limit of 0.67µM and recoveries in the range of 99.5-102.3%, the fluorescent probe showed satisfactory reliability.

Pharmacist's knowledge and attitude towards self-medication practices: a cross-sectional study for the development and validation of questionnaire.

Pharmacists play an essential role in self-medication by providing guidance and counselling services to consumers; hence, it is necessary to assess pharmacists' awareness and attitude towards self-medication to promote responsible self-medication practices. To develop a valid and reliable instrument to assess the knowledge and attitude of pharmacists towards self-medication practices and their role in promoting responsible self-medication. A questionnaire was developed in English after a relevant literature review, which was further administered to a sample of 105 community pharmacists. The reliability of the questionnaire was assessed using the Karl-Pearson correlation and Cronbach alpha statistics. Content validity was evaluated by subject experts. The dimensional structure of items was assessed through exploratory factor analysis and confirmatory factor analysis (CFA). The final questionnaire comprises 27 items for knowledge and attitude with a Karl-Pearson correlation value of 0.896 and Cronbach alpha value of 0.814 (24 items), indicating good internal consistency and reproducibility. Factor analysis identified five factors: namely, (i) attitude towards providing guidance and advice to consumers to promote responsible SMP, (ii) attitude towards shared responsibility for promoting rational medicine supply and use, (iii) knowledge of the advantages and disadvantages of SMP, (iv) knowledge of the definition of self-medication, (v) attitude towards professional competency of a pharmacist as a healthcare provider. CFA results demonstrate good model fit with the value of Chi-square (184.56), CFI (0.937), RMSEA (0.054), and SRMR (0.075). Model validity measures ensure satisfactory validity and reliability. The findings demonstrate a valid and reliable measure for assessing the knowledge and attitude of pharmacists towards self-medication.

Translating the behaviour change technique taxonomy version 1 into Spanish: Methodology and validation

Background Precise and unequivocal specification of intervention content is key to facilitating the accumulation and implementation of knowledge. The Behaviour Change Technique Taxonomy v1 (BCTTv1) is the most widely used classification of behaviour change techniques (BCTs), providing a shared, standardized vocabulary to identify the active ingredients of behavioural interventions. However, the BCTTv1 is only available in English and this hampers its broad use and adoption. The aim of the present article is to report the process of translation of the BCTTv1 into Spanish. Methods A bilingual team led the translation of the BCTTv1, involving seven iterative steps: (i) establish a Committee, (ii) forward translation from English to Spanish, (iii) back translation from Spanish to English, (iv) comparison of original BCTTv1 and back translation, (v) opportunistic comparison against an independent BCTTv1 translation, (vi) empirical testing, and (vii) final Committee review. Results Changes as a result of the translation process included relabelling BCTs, amending definitions, and fixing conceptual and grammatical inconsistencies, yielding the final version. Very satisfactory inter-coder reliability in BCT identification was observed as part of the empirical testing (i.e., prevalence and bias-adjusted kappa scores &gt; 0.8). Conclusions This work provides the Spanish-speaking population with a rigorous and validated BCTTv1 translation which can be used in both research and practice to provide a greater level of intervention detail for evidence synthesis, comparison, and replication of behaviour change interventions. The translation process described here may prove helpful to guide future translation efforts in behavioural science and beyond.

Translation and Cross-Cultural Adaptation, Reliability and Validation Study of the Persian Version of Kansas City Cardiomyopathy Questionnaire

The Kansas City Cardiomyopathy Questionnaire (KCCQ) has been developed to measure the health status of Congestive heart failure (CHF) patients. This study aimed to translate KCCQ into a Persian version and assess its validity and reliability. We used a forward-backward procedure to translate the questionnaire. In a cross-sectional study, 150 CHF patients and 50 healthy subjects over 30 years old were selected to assess the reliability and construct validity of the instrument. The face and content validity were used for the questionnaire's validity. The validity was examined on a population of patients with CHF using the Persian version of the Minnesota Living Heart Failure Questionnaire (MLHF) health survey. Calculation of the Intraclass correlation coefficient (ICC) and Cronbach's alpha was done to evaluate the questionnaire's reliability. Test-retest reliability was examined by re-administering the KCCQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all domains was higher than 0.93, P≤0.000). Internal consistency was found by Cronbach's alpha to be 0.86 for the clinical summary and 0.87 for the overall summary, respectively. Also, the correlation between the components of KCCQ and MLHQ showed satisfactory construct validity. Good Pearson's Correlation Coefficient was seen between KCCQ and MLHF (r= -0.44, P≤0.000 for the clinical summary; r= -0.45, P≤0.000 for the overall summary). Analysing the data from 50 healthy persons and 150 patients were shown that the Persian version of KCCQ has acceptable discriminate validity for all domains except self-efficacy. The Persian version of the KCCQ had satisfactory reliability and validity for assessing health-related quality of life status for Iranian CHF patients.

Preliminary validation of the Norwegian version of the Berlin Misophonia Questionnaire Revised (BMQ-R-NOR).

To perform a psychometric evaluation of a Norwegian version of the Berlin Misophonia Questionnaire Revised (BMQ-R-NOR). Participants completed online versions of the self-report questionnaire BMQ-R-NOR on two occasions and MQ-NOR on one occasion. Convergent validity was assessed through Spearman's correlation between BMQ-R-NOR and MQ-NOR. Internal consistency was evaluated with McDonald's omega and Cronbach's alpha. Test-retest reliability was evaluated using Cohen's weighted kappa and intraclass correlation. 82 participants with self-reported misophonia took part in the study at T1, and 53 of these participated at T2. However, only 41 of them were included in the test-retest analyses due to 12 participants being in treatment between T1 and T2. Subscales from the BMQ-R-NOR and MQ-NOR were significantly positively correlated, indicating evidence of convergent validity (rs = 0.22*-0.74**). The BMQ-R-NOR showed overall good internal consistency (omega = 0.72-0.93; alpha = 0.70-0.93) and satisfactory test-retest reliability (ICC = 0.35-0.92). The psychometric properties of the BMQ-R-NOR are considered satisfactory. However, it is advised to exercise caution when using it until further comprehensive validation studies are conducted to ensure robustness and reliability in clinical practice.

Psychometric Validation of the Multifactor Leadership Questionnaire Form 6-S in Indian Context

The purpose of this study was to examine the factor structure and reliability of the Multifactor Leadership Questionnaire Form 6S (MLQ-6S) for use with Indian corporate leaders. Data was collected from 321 leaders employed across public (n = 165) and private (n = 156) sector organizations via convenience sampling. Before conducting exploratory factor analysis (EFA), tests of normality, sphericity, and sampling adequacy were performed to check statistical assumptions. EFA revealed a 3-factor structure consistent with the MLQ-6S factors of transformational, transactional, and laissez-faire leadership as measured by the 21 items. All factor loadings exceeded 0.5, supporting retention of the original item set. Reliability was assessed using Cronbach’s alpha and split-half coefficients. The overall MLQ-6S scale achieved good reliability (α = 0.719; split-half = 0.664), meeting common psychometric standards. These findings provide evidence that the MLQ-6S demonstrates satisfactory factor structure and reliability for use in assessing leadership behaviors among Indian organizational leaders.

Initial Validation of the Coach-Athlete Relationship Questionnaire in a Sample of Portuguese Athletes.

Our primary objectives in this study were to translate and provide psychometric support for the Coach Athlete Relationship Questionnaire (CART-Q) Portuguese version, assess its invariance across sex, and explore its nomological validity in relation to enjoyment. Our sample participants were 470 athletes (226 females, 244 males) aged between 16 to 39 years from various individual and team sports. We found that the translated Portuguese version of the CART-Q exhibited satisfactory test-retest reliability and can serve as a reliable tool for evaluating the core constructs of the coach-athlete relationship - closeness, commitment, and complementarity. Moreover, this instrument showed evidence of nomological validity through significant positive correlations between its underlying factors and athletes' enjoyment with their sport. The proposed model for explaining item variance was also found to be invariant between male and female respondents. We recommend further use of this instrument in research and practical applications.
