Validation of the 12-item Gamification User Types Hexad Scale in 1,610 Hong Kong Young Gamers

AbstractThe present study aimed to examine the psychometric properties of the Gamification User Types Hexad Scale (Hexad) and validate the 12-item short version (Hexad-12) in the Chinese context. An online survey recruited 1,610 young gamers aged between 11 and 29 (mean age = 23.1, SD = 4.18) in Hong Kong between May and June 2023, who completed the Hexad-24 and other validated measures. Factorial validity and measurement invariance of Hexad were evaluated by confirmatory factor analysis. Convergent validity of Hexad factors was examined with demographic and gaming characteristics, social support, internet gaming disorder (IGD) symptoms, depressive symptoms, and hikikomori. The 6-factor model provided mediocre fits (comparative fit index < 0.90 and standardized root mean square residuals > 0.07) to the original 24-item Hexad but adequate fits (comparative fit index = 0.97 and standardized root mean square residuals < 0.04) to Hexad-12 in split samples with substantial factor loadings and acceptable reliability. The Hexad-12 factors showed scalar measurement invariance across gender, age groups, and game genre. Disruptor was positively and moderately to strongly correlated with IGD and depressive symptoms, hikikomori, and suicidal ideation. Philanthropist and socializer were positively and moderately correlated with social support and meaning in life; free-spirits and achievers were negatively and weakly correlated with IGD and depressive symptoms, hikikomori, and suicidal ideation. The present findings demonstrated adequate psychometric properties for the Hexad-12, supporting its use for brief assessment of Chinese gamers' user types.

Turkish version of a short nutrition literacy scale for young adults: cultural adaptation and validation.

Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent. The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023). This research involved 115 young adults from Istanbul Gelişim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups. As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ2/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults. The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.

Проверка измерительной инвариантности для тестов когнитивных и языковых способностей

<p style="text-align: justify;">This paper discusses the measurement invariance of assessment instruments. The purpose of measurement invariance testing is to assess the extent to which a measured construct has comparable meaning across different groups or measurement points, to ensure that comparisons of these groups or measures to each other are appropriate. The paper provides an overview of recent and classic papers discussing conceptual and methodological aspects of invariance testing. Specific focus is placed on the available data on invariance testing for the assessments of cognitive and language abilities, and on the significance of invariance for the accurate assessment of individual and between-group differences. Finally, current approaches to invariance testing within structural equation modelling and item response theory are discussed. This paper may serve as an introduction to the concept of measurement invariance. It will be useful to readers interested in improving the quality of measurement instruments and making more reliable inferences about psychological phenomena.</p>

Longitudinal measurement invariance and psychometric properties of the Patient Health Questionnaire-Four in China

BackgroundDepression and anxiety symptoms among medical students are often a concern. The Patient Health Questionnaire-Four (PHQ-4), an important tool for depression and anxiety screening, is commonly used and easy to administer. This study aimed to assess and update the longitudinal measurement invariance and psychometric properties of the simplified Chinese version.MethodsA three-wave longitudinal survey was conducted among healthcare students using the PHQ-4. Structural validity was based on one-factor, two-factor, and second-order factor models, construct validity was based on the Self-Rated Health Questionnaire (SRHQ), Sleep Quality Questionnaire (SQQ), and Rosenberg Self-Esteem Scale (RSES), and longitudinal measurement invariance (LMI), internal consistency, and test–retest reliability were based on structural consistency across three time points.ResultsThe results of the confirmatory factor analysis indicated that two-factor model was the best fit, and LMI was supported at three time points. Inter-factor, factor-total, and construct validity correlations of the PHQ-4 were acceptable. Additionally, Cronbach’s alpha, McDonald’s omega, and the intraclass correlation coefficient demonstrated acceptable/moderate to excellent reliability of the PHQ-4.ConclusionsThis study adds new longitudinal evidence that the Chinese version of the PHQ-4 has promising LMI and psychometric properties. Such data lends confidence to the routine and the expanded use of the PHQ-4 for routine screening of depression and anxiety in Chinese healthcare students.

Adolescents’ School-Based Universal Well-Being Screening: A Validation of the Student Subjective Wellbeing Questionnaire in Portugal

AbstractSchool-based universal well-being screening is proposed within the Multi-tiered Systems of Support approach to collect data on school and individual well-being. Universal screening allows for data-based informed decision, allocating each pupil or set of pupils in universal, selective and/or indicated structured interventions and supports. However, schools require adequate and validated measures of both positive well-being and indicators of psychological health problems. This study focused on the adaptation and validation of the Student Subjective Wellbeing Questionnaire (SSWQ) in Portugal, a tool directed to positive well-being screening. After a translation process, data was collected in 10 schools. A sample of 942 school pupils in the 3rd cycle was randomly split into two subsamples. First was conducted on one subsample, and then, CFA was conducted in the other. Gender and school year invariance were also conducted with the CFA subsample. Internal consistency was likewise analysed. The analysis finished with convergent and discriminant validity. Overall, results supported a second-order factor model (subjective well-being), including four first-order factors, with the elimination of one item and changing one item to another subscale. Results showed good reliability of each factor (all above 0.70). Full measurement invariance was reached for gender (male and female) and school year (7th, 8th and 9th grades). Convergent validity was found with measures of satisfaction with school, group identification with peers and school social support, and divergent validity was found with BPM-Y. Altogether, results support that SSWQ-PG can be used to screen for subjective well-being in schools, helping schools in identifying and addressing pupils’ mental health needs more effectively.

Parameter-dependent conditions for H ∞ stabilisation of polynomial parameter-varying system with delay

This paper considers the problems of achieving exponential stability and H ∞ stabilisation for polynomial parameter-varying system with time-varying delay. Unlike some existing linear parameter-varying results that treat system parameters as time invariant factors, this paper makes full use of the nonlinearity and time-varying characteristics of system through introducing a novel delay-and-parameter-dependent Lyapunov function. The main conclusions are discussed in three cases (system without input, system with disturbance input, system with disturbance input and control input). And the H ∞ stabilisation problem is solved by constructing a controller which is inserted with system parameters and their derivatives. The structures of Lyapunov function and controller lead to that the derived criteria for exponential stabilisation are expressed by state-and-parameter-dependent linear matrix inequalities, which are efficiently solved by sum-of-squares program. The effectiveness and superiority are verified through two numerical examples.

Protocol for a systematic review evaluating psychometric properties and gender-related measurement (non)invariance of self-report assessment tools for autism in adults

BackgroundGiven the recent evidence on gender differences in the presentation of autism, there is an increasing concern that current tools for autism do not adequately capture traits more often found in women. If tools for autism measure autistic traits differently based on gender alone, their validity may be compromised as they may not be measuring the same construct across genders. Measurement invariance investigations of autism measures can help assess the validity of autism constructs for different genders. The aim of this systematic review is to identify and critically appraise the psychometric properties of all self-report tools for autism in adults that meet two criteria: (a) they have been published since or included in the NICE (2014) recommendations, and (b) they have undergone gender-related measurement invariance investigations as part of their validation process.MethodsA search of electronic databases will be conducted from 2014 until the present using MEDLINE, Embase, and PsycINFO using predefined search terms to identify eligible studies. The search for grey literature will include sources such as OpenGrey, APA PsycEXTRA, and Scopus. Two reviewers will independently screen titles, abstracts, and full texts for eligibility. The references of included studies will be searched for additional records. The methodological quality of the studies will be evaluated using the COSMIN Risk of Bias checklist, while psychometric quality of findings will be assessed based on criteria for good measurement properties and ConPsy checklist. The quality of the total body of evidence will be appraised using the approach outlined in the modified GRADE guidelines.DiscussionThis systematic review will be among the first to assess the psychometric properties and gender-related measurement invariance of self-reported measures for autism in adults that were published since (or included in) NICE (2014) guidelines. The review will provide recommendations for the most suitable tool to assess for autism without gender bias. If no such measure is found, it will identify existing tools with promising psychometric properties that require further testing, or suggest developing a new measure.Systematic review registrationThe protocol has been registered at the International Prospective Register of Systematic Reviews (PROSPERO). The registration number is CRD42023429350.

Academic Culture: Its Meaning, Measure and Contribution to Student Learning

This study had two objectives. One objective was to assess the psychometric properties of a survey instrument measuring a new latent variable, Academic Culture (AC), combining three observed variables academic press, disciplinary climate and teachers’ uses of instructional time. The second objective was to replicate the results of an earlier study identifying AC as a significant mediator of school leadership’s influence on student learning. Data for the study were provided from 2068 teachers located in 49 schools in 14 Texas school districts, as well as student achievement data from the State of Texas Assessments of Academic Readiness (STAAR) and student socioeconomic (SES) data available from school websites. Second order Confirmatory Factor Analysis (CFA) and Many-Facet Rasch (MFR) models were used to examine the survey instrument’s construct validity and its measurement invariance. Structural Equation Modeling was used to identify the extent to which AC mediated the effects of school leadership on student achievement controlling for student SES. Rasch analysis and CFA confirmed the measurement invariance and several forms of validity of the survey instrument. Replicating the results of an earlier study, results of structural equation modeling demonstrated significant effects of AC on student achievement and identified AC as a significant mediator of school leadership effects on student achievement. The study contributes to the quality of instruments available to school leaders for their school improvement work and to researchers inquiring about the most promising variables mediating the indirect effects of school leadership on student success.

Conducting cross-cultural, multi-lingual or multi-country scale development and validation in health care research: A 10-step framework based on a scoping review.

Valid, reliable and cross-cultural equivalent scales and measurement instruments that enable comparisons across diverse populations in different countries are important for global health research and practice. We developed a 10-step framework through a scoping review of the common strategies and techniques used for scale development and validation in a cross-cultural, multi-lingual, or multi-country setting, especially in health care research. We searched MEDLINE, Embase, and PsycINFO for peer-reviewed studies that collected data from two or more countries or in two or more languages at any stages of scale development or validation and published between 2010-22. We categorised the techniques into three commonly used scale development and validation stages (item generation, scale development, and scale evaluation) as well as during the translation stage. We described the most commonly used techniques at each stage. We identified 141 studies that were included in the analysis. We summarised 14 common techniques and strategies, including focus groups or interviews with diverse target populations, and involvement of measurement experts and linguists for item content validity expert panel at the item generation stage; back-and-forth translation, collaborative team approach for the translation stage; cognitive interviews and different recruitment strategies and incentives in different settings for scale development stage; and three approaches for measurement invariance (multigroup confirmatory factor analysis, differential item functioning and multiple indicator multiple causes) for scale evaluation stage. We provided a 10-step framework for cross-cultural, multi-lingual or multi-country scale development and validation based on these techniques and strategies. More research and synthesis are needed to make scale development more culturally competent and enable scale application to better meet local health and development needs.

Factor structure and psychometric properties of the L2 teacher boredom scale

The attention of researchers in the field of second language acquisition (SLA) has recently been drawn to boredom, recognized as one of the most prevalent and distressing emotions experienced by second and/or foreign language (L2) students. However, studies delving into boredom experienced by L2 teachers rather than learners are few and far between. This oversight is significant, considering that the emotions of both learners and teachers are bound to interact and feed into each other in classroom settings. In order to address this gap, the present research aimed to examine the factor structure and psychometric properties of the L2 Teacher Boredom Scale (L2TBS). The questionnaire was administered to 225 L2 teachers from different countries (e.g., Poland, Turkey, Hungary, Iran, USA). Data were subjected to exploratory factor analysis, confirmatory factor analysis and exploratory structural equation modeling (ESEM). The results identified the ESEM solution as the optimal model for measuring L2TBS. Five factors contributing to teacher boredom were identified: (F1) repetitiveness and monotony, (F2) inefficient communication, (F3) lack of satisfaction, (F4) lack of creativity, and (F5) lack of interest. The analysis also provided evidence for measurement invariance across gender, age, education and years of teaching experience.

Chronic and contextual identity salience: Assessing dual-dimensional salience with the Identity Salience Questionnaire (ISQ)

ABSTRACT Identity Salience is a common construct within social identity research. However, researchers note that it is poorly defined and inconsistently operationalized. We posit that identity salience comprises two elements: chronic (perpetually thinking about the identity) and contextual (only thinking about the identity when prompted) salience. We present evidence for this claim through the development and validation of the dual-dimensional Identity Salience Questionnaire (ISQ). Studies 1-2 (Ns=414; 1,069) provide exploratory and confirmatory factor analytic evidence of the ISQ among LGBTIQA+ participants. Study 2 also provides evidence of measurement invariance, convergent, predictive, and discriminant validity, and internal reliability. Study 3 (N=318) indicates strong test-retest reliability. Study 4 (N=107 social psychologists) confirms the ISQ’s content validity. Future research for the ISQ is discussed.

Racial Differences in Psychosocial Resources and Mental and Physical Health Outcomes during Pregnancy: A structural equation modeling approach.

Poor prenatal health is of particular concern among minoritized individuals who may experience adverse social determinants of health contributing to the intergenerational transmission of health disparities. The purpose of this study was to investigate associations between psychosocial resources, and mental and physical health among a prenatal sample, and to explore if these relationships vary by race. English-speaking pregnant individuals living in the United States were recruited using Centiment (n=340). Participants completed a 121-item cross-sectional survey. We conducted a single- and multi-group structural equation model to test hypothesized relationships, and then investigated differences by pregnant White individuals versus Black, Indigenous, and People of Color (BIPOC). Our final single-group model exhibited good model fit (χ2 (43) = 99.07, p<.01, CFI = 0.97, SRMR = 0.04, and RMSEA = 0. 06 (0.05 - 0.08)). After controlling for demographic characteristics and social determinants of health, higher levels of mindfulness were statistically significantly related to lower anxiety and depression scores (both p<.01). Higher levels of social supports were statistically significantly related to lower anxiety scores. Scale measurement invariance was confirmed for the multi-group model and the structural model was statistically significantly different between pregnant White individuals and BIPOC in this sample (Δ χ2 (27) = 116.71, p <.01). Identification of core components of psychosocial resource interventions, consideration of upstream structural determinants, mindfulness and valued-living (MVL)-based strategies, cultural adaptation, and an emphasis on resilience rather than psychopathology may result in improved prenatal health among pregnant individuals traditionally underrepresented in research.

Measurement invariance of the action competence in sustainable development questionnaire: can we compare between groups?

There is a need for valid and reliable instruments to assess learning outcomes in education for sustainable development (ESD). Measurement invariance (MI) needs to be established before results of these instruments can be validly compared between groups. Despite its importance, establishing MI is an often overlooked validation step. To provide an example of testing for MI in the field of ESD, thereby setting a precedent for subsequent studies, this study tested the MI of the Action Competence in Sustainable Development Questionnaire (ACiSD-Q). First, Confirmatory Factor Analyses (CFAs) were carried out to make refinements to the original model. Subsequently, nested multiple-group CFAs were performed to test for MI of the ACiSD-Q for the grouping variables of educational level (primary versus secondary), language spoken at home (instructional language versus other languages), and gender. Model fit indices of the refined model and the ACiSD-Q’s proneness to MI are discussed.

Feedback engagement as a multidimensional construct: a validation study

While the term feedback engagement has become a buzzword in higher education, the constructs of feedback engagement have remained inadequately investigated, and research on the conceptualization and instrumentation of feedback engagement in the literature is limited. This paper presents the development and validation of a feedback engagement scale that both reflects a prevalent multidimensional perspective of engagement in general education and is grounded in the prior empirical feedback research. Psychometric tests were conducted with a large disciplinarily diverse sample of university undergraduate students (N = 872). Findings of both confirmatory factor analysis and multi-group confirmatory factor analysis provide evidence of reliability, validity, and measurement invariance, for capturing the behavioural, cognitive, emotional, and social components of feedback engagement in higher education settings. The feedback engagement scale can be utilized both as a diagnostic tool for teachers to assess the level of student feedback engagement in academic learning and as a research tool for researchers to investigate the dynamic interplays between student feedback engagement and other learner/learning achievement variables.

Illegitimate work tasks: an investigation of psychometric properties of the Swedish version of the BITS instrument and its suitability in human versus ‘non-human’ service occupations

BackgroundIllegitimate tasks, i.e. working tasks that are perceived as unnecessary or unreasonable, are commonly measured by the Bern Illegitimate Tasks Scale (BITS). Despite a growing research attention paid to illegitimate tasks, the Swedish version of BITS needs yet to be properly evaluated. Moreover, previous multiorganizational studies in this field have taken for granted, without really testing it, that the instrument functions invariantly in different contexts; a prerequisite for meaningful comparisons.MethodsTwo occupational groups that differs hugely—966 human services workers (teachers and registered nurses) and 750 non-’human service’ workers (construction and IT-workers) were targeted utilizing questionnaires data collected 2018 within the Swedish Longitudinal Occupational Survey of Health (SLOSH) study. Psychometric properties, i.e., reliability, dimensionality, and measurement invariance between the occupations were examined using confirmatory factor analyses and structural equation models. Also, the associations between the two dimensions of illegitimate tasks and job satisfaction and emotional exhaustion, respectively, were tested.ResultsGood reliability was supported and two- versus one-dimensionality showed better psychometric properties. Partial scalar measurement invariance was satisfactory supported with only 25% relaxed constraints of equal intercepts between groups. Examining the two subdimensions revealed different associations with emotional exhaustion, where the associations was more substantial for unreasonable tasks. Nevertheless, the findings point to potential improvements for future investigation.ConclusionsThis study shows that the Swedish version of BITS is working satisfactory and allows for meaningful comparisons of occupational groups. Furthermore, construct validity of the two dimensions was corroborated.

Measurement invariance of the Suicide Cognitions Scale-Revised (SCS-R).

The Suicide Cognitions Scale-Revised (SCS-R) is a unidimensional measure of suicidal cognitions theorized to assess the suicide belief system. Several solutions have been proposed for the Suicide Cognitions Scale and SCS-R (e.g., bifactor model with two specific factors, bifactor model with two specific factors, three correlated factors model). Research indicates the endorsement of thoughts of suicide and suicide-related cognitions varies across demographics. Thus, the current investigation tested the measurement invariance (MI) of the SCS-R across gender, race, and sexual orientation within these proposed solutions and a unidimensional model. A national sample of N = 10,625 adults completed an online survey that included the SCS-R and self-report measures of demographics. Results indicated that the bifactor model with three specific factors, the bifactor model with two specific factors, and the three correlated factors models achieved scalar invariance across gender, race, and sexual orientation; a unidimensional model was not scalar invariant by gender. Tests of latent mean differences revealed significant differences in the general factor (i.e., suicidal belief system) and the specific unlovability, unbearability, and unsolvability factors between a few demographic groups. Implications for theory, measurement, and modeling are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Psychometric properties of the KCCQ-12 in an 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.

Factor structure and invariance of the 12-item general health questionnaire (GHQ-12) for a sample of people in situations of homelessness

ABSTRACT People in situations of homelessness (PSH) have high levels of psychological impairment. Few studies have analyse the suitability of the instruments used to measure these levels. The aim of this study was to analyse the factorial structure and invariance (sex, age, nationality and housing status) of the 12-item General Health Questionnaire (GHQ-12) for a sample of PSH (n = 603) living in the Community of Madrid (Spain). A quantitative study was designed using a survey that include the GHQ-12 and other health measures (self-assessed health and diagnosis of mental illness). A comparison of three models (unidimensional, two correlated latent factors and bi-factor) showed that the bi-factor model provided the best goodness-of-fit indicators. A latent structure was identified in which each item was loaded into a general factor measuring a single GHQ-12 factor. The number of latent factors and the structure of factorial loads for GHQ-12 items were similar between groups. The GHQ-12 can be used as a screening instrument rather than as an outcome measure in different clinical dimensions. It is an appropriate instrument for assessing psychological impairment among PSH regardless of sex, age, nationality or housing status.

Multifactorial Memory Questionnaire: a comparison of young and older adults

ABSTRACT The Multifactorial Memory Questionnaire (MMQ; Troyer & Rich, [2002]. Psychometric properties of a new metamemory questionnaire for older adults. The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 57(1), P19–P27) is a widely used measure of subjective memory consisting of three scales: Satisfaction, Ability, and Strategies. Although subjective memory complaints are prevalent across different age groups, the factor structure and psychometric properties of the MMQ have yet to be examined in young adults. Here, we independently replicated the original MMQ factor structure in N = 408 young adults (YA) recruited from undergraduate courses and N = 327 older adults (OA) and, for the first time, assessed the age-invariance of the scale using measurement invariance testing. YAs made significantly higher ratings than OAs on MMQ-Satisfaction and MMQ-Strategies, indicating greater satisfaction with their memory and greater use of strategies, but the groups were similar on MMQ-Ability. The original MMQ factor structure was replicated in OAs but not in YAs, and age invariance was not supported. Future studies seeking to compare young and older adults could therefore consider either requesting modification of the MMQ for use with young adults or using a different scale.

Psychometric analysis of the kansas city cardiomiopathy questionnaire-23 in a european population

Abstract Background People affected by heart failure (HF) often exhibit poor quality of life, which places a great deal of burden on the healthcare systems. The Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 is one of the most widespread instruments to measure quality of life in this population. So far, its psychometric properties have been investigated by a broad array of research, but the overall findings reveal inconsistency of the factorial structure and lack of rigorous psychometric testing. Objective The aim of this study was to evaluate the psychometric properties of the KCCQ-23 in a European cohort of HF patients. Methods The data used for this study were collected for the MOTIVATE-HF study, which was a three-arm, multicenter, randomized controlled trial to evaluate the effect of motivational interviewing for improving self-care in HF. A group of 510 patients (median age 74 years, IQR=18, 58% males) completed the KCCQ-23 along with clinical and psychosocial measures. Factorial validity was established with confirmatory factor analysis (CFA); omega and model-based internal consistency indexes were computed to examine the internal consistency of the scale. Convergent validity was established by correlating the KCCQ-23 scores with several clinical and psychosocial measures. Measurement invariance testing was conducted within a multigroup framework across patients with preserved vs those with reduced ejection fraction. Results Two CFA solutions were tested, which confirmed the theoretical and empirical models postulated by the original author. The internal consistency coefficients for the latent dimensions were adequate (Omega range =0.77-0.93; internal consistency coefficient =0.89-96)- KCCQ-23 scores were found to be correlated with ejection fraction, NYHA levels, quality of life, self-care confidence, anxiety and depression, and symptom burden, supporting its convergent validity. Finally, the KCCQ-23 was invariant across ejection fraction levels, both in the theoretical and empirical factor solution. Conclusion Overall, this study provides for the first time evidence that the KCCQ-23 has satisfactory psychometric properties, promoting its use in clinical settings and research to investigate the quality of life in patients with HF.
