Confirmatory Factor Analysis (CFA), Exploratory Structural Equation Modeling (ESEM), and Set-ESEM: Optimal Balance Between Goodness of Fit and Parsimony

The Translation and Preliminary Psychometric Validation of the Ghosting Questionnaire in Urdu

BACKGROUND

"Ghosting" refers to the practice of abruptly cutting off all contact with a person with whom you have been in constant correspondence. The break comes without warning and without understandable provocation. The term most commonly applies to online romantic relationships. The motives for and effects of ghosting have been studied, and validated research questionnaires have been developed; however, there are no such questionnaires available for Urdu speakers. The purpose of this study was to adapt the "Ghosting Questionnaire (GQ)" for use in Pakistan and India, two of the world's most populous countries-a process that involves translation, adaptation, and validation.

METHODS

The study's methodology involved translating the GQ into Urdu using both forward and backward translation techniques. Convergent validity, test-retest reliability, internal consistency, confirmatory factor analysis, and goodness of fit were all components of the psychometric analyses.

CONCLUSIONS

The Urdu version of the GQ demonstrated a good internal consistency, with the Cronbach's alpha and McDonald's omega both exceeding 0.90. It also showed a high test-retest reliability-(0.96). The one-factor structure was confirmed by the confirmatory factor analysis, which agreed with the original English version of the GQ.

Designing and evaluating tasks to measure individual differences in experimental psychology: a tutorial

Experimental psychology is witnessing an increase in research on individual differences, which requires the development of new tasks that can reliably assess variations among participants. To do this, cognitive researchers need statistical methods that many researchers have not learned during their training. The lack of expertise can pose challenges not only in designing good, new tasks but also in evaluating tasks developed by others. To bridge the gap, this article provides an overview of test psychology applied to performance tasks, covering fundamental concepts such as standardization, reliability, norming and validity. It provides practical guidelines for developing and evaluating experimental tasks, as well as for combining tasks to better understand individual differences. To further address common misconceptions, the article lists 11 prevailing myths. The purpose of this guide is to provide experimental psychologists with the knowledge and tools needed to conduct rigorous and insightful studies of individual differences.

The Psychometric Properties of the Arabic Version of the Anxiety and Preoccupation About Sleep Questionnaire (APSQ)

Background

Insomnia disorder is a common health condition; it has a role in increasing the possibility of developing other psychological disorders, including anxiety and depression. Anxiety and preoccupation with sleep are two examples of common cognitive factors that contribute to the development of chronic insomnia; thus, it is important to have a tool that assesses worry in insomnia. There is no comprehensive psychiatric measure to assess anxiety and preoccupation with sleep in Arabic. We conducted this study to translate, adapt, and validate the Arabic version of the Anxiety and Preoccupation about Sleep Questionnaire (APSQ), providing a reliable psychometric tool to assess concerns regarding sleep within Arabic-speaking communities.

Methods

The translation process of the scale involved several steps, including forward and backward translation. A cross-sectional study was conducted using an online survey completed by 523 participants from various Arabic-speaking countries. Psychometric analysis was performed utilizing the R software, including internal consistency, test-retest reliability, and confirmatory factor analysis. In addition, convergent and divergent against the Athens insomnia scale (AIS) and general anxiety disorder (GAD) were conducted.

Results

The Arabic-translated form of the APSQ expresses excellent internal consistency with a value of 0.91 for both Cronbach's α and McDonald's ω. The test-retest reliability of a subsample showed an excellent coefficient of 0.93 (p<0.01). A good fit of the APSQ was observed by CFI = 0.93, TLI = 0.91, SRMR = 0.05, and RMSEA = 0.1. Convergent and divergent against AIS and GAD showed statistically significant correlations of 0.85 (p<0.01) and 0.69 (p<0.01), respectively. Our sample showed a mean APSQ score of 31.28 ± 8.31, and the mean age was 23.62 ± 7.5.

Conclusion

The Arabic APSQ is reliable and valid for measuring anxiety and preoccupation with sleep in Arabic countries. Using translated APSQ for clinical diagnosis and research is currently trustworthy.

Psychometric properties of the Turkish version of the Stress Scale for Nurses Providing End-of-Life Care for Children

OBJECTIVES

This study was carried out to evaluate the validity and reliability of the Stress Scale for Pediatric Nurses Performing End-of-Life Care for Children in Turkey.

METHODS

This was a methodological study conducted with 222 pediatric nurses. Data were collected using the information form for pediatric nurses and the "stress scale for nurses performing end-of-life care for children." Content and construct validity, item analysis, confirmatory factor analysis and internal consistency were used to evaluate the data. The Global Pharmaceutical Regulatory Affairs Summit checklist was followed in this study.

RESULTS

The content validity index of the scale was 0.93. Item-total score correlation values ranged from 0.594 to 0.885. The 5-factor structure of the scale was confirmed as a result of confirmatory factor analysis. Factor loads were greater than 0.30, and fit indices were greater than 0.80. The Cronbach's alpha coefficient of the Turkish version of the scale was 0.97.

SIGNIFICANCE OF RESULTS

The stress scale for nurses performing end-of-life care for children is a valid and reliable measurement tool for the Turkish sample. This scale facilitates the assessment of the stress levels of pediatric nurses who provide end-of-life care to children. Also, this scale can be used in interventional studies to improve the well-being of pediatric nurses.

Development and validation of the Perceived Benefits of Team-Interaction Training Questionnaire (PBTITQ) among undergraduates

BACKGROUND

The effectiveness of team-interaction training has been proven. However, there is a lack of objective and accurate evaluation tools for the impact and benefits of team-interaction training on participants. This study aims to develop and validate a tool for exploring undergraduates' perception of benefits in team-interaction. It can further insight into the perceived benefits of team-interaction training for undergraduates and evaluates the effectiveness of the course, and provides a reference point for the development of university team-interaction training courses.

METHODS

This study was conducted in three stages. Phase 1 consisted of item generation: A theoretical framework was crafted based on social cognitive theory, self-efficacy theory, and sports performance models. Fifty-two items were generated based on the theoretical framework, participant interviews, and literature review. After Delphi consultation and pilot tests, 39 items moved on to Phase 2. Phase 2 consisted of forming a preliminary questionnaire: the contents to be included were selected through item analysis and exploratory factor analysis (EFA). A total of 40 classes were selected for EFA. After EFA, a three-factor structure with 25 items was formed. The third stage tested psychometric properties through confirmatory factor analysis (CFA), test-retest reliability, criterion-related validity, and internal consistency.

RESULTS

The final PBTITQ consisted of 23 items, each rated from "1" (fully disagree) to "5" (fully agree). EFA and CFA supported the three-factor structure of PBTITQ, which included Cohesion, Communication, and Efficiency. The Cronbach's alpha of the PBTITQ was 0.90, the test-retest reliability was 0.88, and the split-half reliability was 0.81. PBTITQ significantly correlated with the GEQ (r = 0.808, p < 0.05) and the TDM (r = 0.796, p < 0.05).

CONCLUSION

The PBTITQ is an effective tool for assessing the perceived benefits of team-interaction training among undergraduates.

Exploratory Bi-factor Analysis with Multiple General Factors

Exploratory bi-factor analysis (EBFA) is a very popular approach to estimate models where specific factors are concomitant to a single, general dimension. However, the models typically encountered in fields like personality, intelligence, and psychopathology involve more than one general factor. To address this circumstance, we developed an algorithm (GSLiD) based on partially specified targets to perform exploratory bi-factor analysis with multiple general factors (EBFA-MGF). In EBFA-MGF, researchers do not need to conduct independent bi-factor analyses anymore because several bi-factor models are estimated simultaneously in an exploratory manner, guarding against biased estimates and model misspecification errors due to unexpected cross-loadings and factor correlations. The results from an exhaustive Monte Carlo simulation manipulating nine variables of interest suggested that GSLiD outperforms the Schmid-Leiman approximation and is robust to challenging conditions involving cross-loadings and pure items of the general factors. Thereby, we supply an R package (bifactor) to make EBFA-MGF readily available for substantive research. Finally, we use GSLiD to assess the hierarchical structure of a reduced version of the Personality Inventory for DSM-5 Short Form (PID-5-SF).

Media Parenting Scale for School-Aged Children (MEPA-20): Psychometric Properties of the Turkish Version

BACKGROUND AND PURPOSE

Media parenting refers to the strategies and behaviors parents use to interact with their children regarding the amount, content, and context of screen use. Children's media/screen use is a significant indicator of media parenting practices. Therefore, this study aimed to determine the psychometric properties of the Turkish version of the Media Parenting Scale for School-Aged Children (MEPA-20).

METHODS

This methodological study involved 524 parents with children aged 6-10 and was conducted between October 15, 2022, and February 15, 2023. In the data analysis, the Content Validity Index, Explanatory and Confirmatory Factor Analyses, Cronbach's alpha, Test-retest reliability, Hotelling T2 test, and item-total score correlation were used. The test-retest reliability analysis of the Turkish version of MEPA-20 was performed with 30 parents after 4 weeks.

RESULTS

MEPA-20 consists of 20 items and three sub-dimensions (active, restrictive, and over-protective mediation). The MEPA-20 Turkish version and its three factors were found to indicate acceptable levels of internal consistency and reliability. The three-factor construct validity of the MEPA-20 Turkish version determined with Explanatory Factor Analyses was successfully confirmed with Confirmatory Factor Analysis.

CONCLUSION

The MEPA-20 is a valid and reliable tool for assessing the media parenting practices of parents of children aged 6-10 years in the Turkish population.

PRACTICE IMPLICATIONS

Based on the impact of media parenting practices on child and family health, nurses should raise awareness and support parents regarding children's healthy screen use.

A guide to exploratory structural equation modeling (ESEM) and bifactor-ESEM in body image research

Traditionally, assessments of factor validity of body image instruments have relied on exploratory or confirmatory factor analysis. However, the emergence of exploratory structural equation modeling (ESEM), a resurgence of interest in bifactor models, and the ability to combine both models (bifactor-ESEM) is beginning to shape the future of body image research. For these analytic approaches to truly advance body image research, scholars will need to have a deep understanding of their use and application. To facilitate such understanding, we describe ESEM and bifactor-ESEM models for body image researchers and provide them with the tools they need to apply these methods in their own work. Specifically, we provide an overview of ESEM and bifactor-ESEM models, and describe their broad applicability to body image research. Next, we describe how ESEM and bifactor models can be used and, using an existing dataset of responses to the Acceptance of Cosmetic Surgery Scale, demonstrate how ESEM and bifactor-ESEM models can be deployed. To facilitate wider application of these ideas, we provide our Mplus syntax (inputs) in Supplementary Materials. Through this manuscript, we hope to assist researchers to better understand the strengths ESEM and bifactor models, and to use these approaches in their own work.

Game on: Can gamification enhance productivity?

Background: Research suggests that gamification can increase work engagement by providing employees with a sense of autonomy, competence, and relatedness, and by creating a fun and engaging work environment. Gamification is designed to increase consumer and employee engagement and see that they holistically collaborate to achieve a shared vision. The concept of gamification is as old as learning itself, just that the use of the terminology "Gamification" is of a recent origin. Methods: This article focuses on the impact of gamification in various organizations and simultaneously sees its relationship with job engagement and productivity. A primary investigation was done to determine the nexus between the various variables and data collection from 400 respondents working in various fraternities of the economy from both public and private domains from countries in the Gulf region. The structural equation model and SPSS has been inferred to analyse the results. Results: The study results show that variable such as perceived adoption and usefulness in the gamified system is significantly associated with job engagement. Similarly, employee's recognition and perceived motivation have a positive impact on productivity. The study identified job engagement mediating factor to enhance organisational productivity in a gamified system. Conclusion: The effectiveness of gamification in enhancing work engagement may depend on factors such as the design of the gamification system, the preferences and motivations of individual employees, and the organizational culture and goals. The findings have significant implications for insight into how employees in the service sector are aware of the gamified working environment and react to the system through work engagement and productivity.

Psychometric properties of the Turkish version of the moral distress-appraisal scale for nurses

Moral distress causes frustration, guilt, anger, stress, sadness, anxiety, fear, burnout, insecurity, and depression in nurses, and this is reflected in their work performances. Therefore, internationally validated tools and methodological studies are needed to measure moral distress among nurses. This study aims to evaluate the psychometric properties of the Turkish version of the Moral Distress-Appraisal Scale (MD-APPS) among nurses in Turkey. Psychometric properties of the Turkish version of the Moral Distress-Appraisal Scale (MD-APPS), which included internal consistency reliability and construct validity with factor analysis, were examined in a sample of 420 nurses working in different hospitals in Turkey completed the study between February and July 2022. The content validity index of the Turkish version of the MD-APPS based on expert opinions was 0.90. Through exploratory factor analysis for construct validity, a two-factor structure was obtained as in the original scale. The variance explained by these two factors was 56.67 %. Confirmatory factor analysis showed that the scale was valid, while internal consistency coefficient and test-retest results demonstrated that the scale was reliable. The Turkish version of the MD-APPS is a valid and reliable tool for evaluating moral distress among nurses.

Introducing the Basic Psychological Needs Frustration in Second Language Scale (BPNF-L2): Examining its factor structure and effect on L2 motivation and achievement

Research on the satisfaction of the basic psychological needs for autonomy, competence, and relatedness is well-established in second language (L2) research. However, little is known about the frustration of these basic psychological needs and how they can undermine intrinsic motivation and L2 achievement. Importantly, there is no valid scale of the frustration of the basic psychological needs in the L2 context. Accordingly, the present study introduces a new scale called the Basic Psychological Needs Frustration in Second Language (BPNF-L2) and assesses its factor structure and criterion-related validity through the application of bifactor exploratory structural equation modeling (bifactor ESEM). Our results showed that scores obtained on the BPNF-L2 scale are reliable and valid. Moreover, our results support the criterion-related validity of this factor structure by showing that the general factor of BPNF-L2 negatively explains intrinsic motivation and L2 achievement while the BPNF-L2 specific factors (i.e., autonomy, competence, and relatedness frustration) explain the outcomes differently. The results indicate that feeling frustrated because basic psychological needs are not met may hinder the enjoyment and acquisition of the L2. Educational implications, methodological advancements, and directions for future research are provided.

Reliability and validity of the Shona version of the Exercise Benefits and Barriers Scale in Zimbabwean adult people living with HIV/AIDS

Introduction

Despite the widely known benefits of physical activity (PA), only 25% of people living with HIV (PLHIV) meet the WHO-recommended minimum PA levels. Consequently, it is essential to understand PA barriers and facilitators using objective measures. Although the Exercise Benefits and Barriers Scale (EBBS) is extensively used, its psychometric evidence is fragmented and has not been previously validated in PLHIV. This study aimed to translate and validate the EBBS Shona version in Zimbabwean PLHIV.

Methods

A cross-sectional study was used to recruit 567 PLHIV from four (4/9) randomly selected polyclinics (primary healthcare facilities) in urban Harare, Zimbabwe. We recruited adult patients (aged ≥18 years) with a confirmed diagnosis of HIV. Participants had to be willing to provide informed consent, not acutely unwell, and proficient in the Shona language. We used a forward-backwards translation method to translate the EBBS from English to Shona, a native Zimbabwean language. After cross-cultural adaptation, we pretested the draft version in 10 PLHIV to assess the face validity, understandability and cultural appropriateness using semi-structured interviews. Thereafter, the EBBS was administered to 567 consecutively-selected PLHIV. Factor analyses were performed for construct validity evaluation.

Results

Most participants were female (72.5%) and reached secondary/high school (78.8%), with a mean age of 39.9 (SD 12.1) years. The EBBS-Shona version yielded a four-factor solution consisting of three benefits factors and one barrier factor against the originally postulated six-factor structure. The EBBS-Shona yielded α = 0.85 and intraclass correlation coefficient = 0.86, demonstrating excellent reliability. Increased perception of exercise benefits was positively correlated with increased reports of physical activity, higher health-related quality of life and lower psychiatric morbidity; evidence for construct validity.

Discussion

This study demonstrates the validity and reliability of the EBBS-Shona version in Zimbabwean PLHIV. The EBBS-Shona version can be used for research and clinical purposes to glean data to inform the development, implementation, and evaluation of bespoke PA interventions for PLHIV.

The Norwegian version of the Copenhagen Psychosocial Questionnaire (COPSOQ III): Initial validation study using a national sample of registered nurses

BACKGROUND

Employers are legally obligated to ensure the safety and health of employees, including the organizational and psychosocial working environment. The Copenhagen Psychosocial Questionnaire (COPSOQ III) covers multiple dimensions of the work environment. COPSOQ III has three parts: a) work environment b) conflicts and offensive behaviours and c) health and welfare. We translated all three parts into Norwegian and evaluated the statistical properties of the 28 work environment dimensions in part a), using a sample of registered nurses.

METHODS

The original English version was translated into Norwegian and back translated into English; the two versions were compared, and adjustments made. In total, 86 of 99 items from the translated version were included in a survey to which 8804 registered nurses responded. Item response theory models designed for ordinal manifest variables were used to evaluate construct validity and identify potential redundant items. A standard confirmatory factor analysis was performed to verify the latent dimensionality established in the original version, and a more exploratory factor analysis without restrictions is included to determine dependency between items and to identify separable dimensions.

RESULTS

The measure of sampling adequacy shows that the data are well suited for factor analyses. The latent dimensionality in the original version is confirmed in the Norwegian translated version and the scale reliability is high for all dimensions except 'Demands for Hiding Emotions'. In this homogenous sample, eight of the 28 dimensions are found not to be separate dimensions as items covering these dimensions loaded onto the same factor. Moreover, little information is provided at the low and high ends of exposure for some dimensions in this sample. Of the 86 items included, 14 are found to be potential candidates for removal to obtain a shorter Norwegian version.

CONCLUSION

The established Norwegian translation of COPSOQ III can be used in further research about working environment factors and health and wellbeing in Norway. The extended use of the instrument internationally enables comparative studies, which can increase the knowledge and understanding of similarities and differences between labour markets in different countries. This first validation study shows that the Norwegian version has strong statistical properties like the original, and can be used to assess work environment factors, including relational and emotional risk factors and resources available at the workplace.

Translating and validating the hoarding rating scale-self report into Arabic

BACKGROUND

Hoarding disorder is characterized by a persistent inability to part with possessions due to a perceived need to keep them, regardless of their actual value. Arabic-speaking populations currently lack a validated tool specifically designed to assess hoarding symptoms.

OBJECTIVE

This study aimed to translate, adapt, and validate the Hoarding Rating Scale-Self Report (HRS-SR) into the Arabic-language.

METHODS

The study employed the gold standard approach to translation, involving forward translation by independent translators and back translation review. We conducted a cross-sectional study using an online survey completed by 500 participants from four Arabic-speaking countries. Psychometric analyses included internal consistency, test-retest reliability, convergent validity against generalized anxiety disorder (GAD-7), and confirmatory factor analysis.

RESULTS

With a McDonald's omega and Cronbach's alpha of approximately 0.80, the Arabic translation of the HRS-SR showed acceptable test-retest reliability as well as good internal consistency. The survey also showed strong convergent validity with the 7-item survey for GAD-7. Confirmatory factor analysis supported a one-factor structure, confirming that each item measured the same construct.

CONCLUSION

The HRS-SR is a trustworthy and valid tool for evaluating hoarding symptoms in Arabic-speaking people. This survey could be helpful for both clinical and academic research. Future research should examine cultural variations in hoarding behavior in Arabic-speaking populations and validate the questionnaire in clinical populations.

Exploratory structural equation modeling: a streamlined step by step approach using the R Project software

Confirmatory Factor Analysis (CFA) has been a popular yet limited approach to assessing latent factor structures. Despite items rarely loading exclusively on one latent factor in multifactorial scales, CFA assumes all indicators/items should load uniquely on their allocated latent dimensions. To address this weakness, Exploratory Structural Equation Modeling (ESEM) combines exploratory factor analyses (EFA) and CFA procedures, allowing cross-loadings to occur when assessing hypothesized models. Although such advantages have enhanced ESEM popularity, its adoption is often limited by software rigidity and complex coding difficulties. To address these obstacles, the current tutorial presents a streamlined, step-by-step approach using the open-source software R while providing both R and Mplus ESEM syntax. The tutorial demonstrates the sequence of the ESEM stages by examining the frequently debated Strengths and Difficulties Questionnaire (SDQ) factor structure, using openly accessible data from the Longitudinal Study of Australian Children (LSAC). As ESEM may allow a better understanding of the complex associations in multidimensional scales, this tutorial may optimize the epidemiological and clinical assessment of common yet multifaceted psychiatric presentations.

COVID-19 meets control-value theory: Emotional reactions to canceled high-stakes examinations

In many countries, examinations scheduled for summer 2020 were canceled as part of measures designed to curb the spread of the COVID-19 pandemic. To examine how four retrospective emotions about canceled examinations (relief, gratitude, disappointment, and anger) and one prospective emotion (test anxiety) were related to control-value appraisals, a sample of 474 participants in the UK aged 15-19 years, who would have taken high-stakes examinations if they had not been canceled, self-reported measures of control, value, retrospective emotions and test anxiety. Data were analysed using the confirmatory factor analysis within exploratory structural equation modeling (EwC) approach. Relief, gratitude, and anger were predicted from expectancy × value interactions. Disappointment was related to expectancy only. Test anxiety was predicted independently by expectancy and positive/negative value. Findings offer broad support for Control-Value Theory and show how the appraisals underpinning achievement emotions can differ when focused on canceled examinations rather than success or failure.

Capturing the impact employees have on their coworkers and leaders: a holistic approach on health-specific support behavior from employees

Support is a valuable resource for ensuring employee health in the workplace. However, research on health-specific support behavior (i.e., support specifically targeting concrete health aspects) has only concentrated on either leader behavior (e.g., healthy leadership styles) or support provided by employees for specific health issues (e.g., healthy eating or smoking cessation). Although the importance of employee health has been well established, the examination of a wider range of potential health-specific support behaviors from employees provided for their colleagues and leaders has been neglected. To understand employee health-specific support behavior, we adapted an existing health-oriented leadership questionnaire to cover support for colleagues (PeerCare) and their leaders (LeaderCare). Capturing the employee perspective with a sample of 347 employees, the results confirmed a delineation of health-oriented scales (factor, convergent, and discriminant validity). By testing health-specific support behavior processes at work, the positive effects of PeerCare on general health were demonstrated. Contrary to expectations, existing health effects are outweighed when leaders provide health-specific support behavior to their employees (StaffCare). However, the results imply that the health-specific support behavior practices of different actors reinforce each other: the effects of StaffCare and PeerCare enhance each other, and StaffCare has a strong influence on LeaderCare. Remarkably, SelfCare has a key role in this process. The open questions and implications regarding the effects of the different health-specific support behavior measurements are discussed.

Psychometric properties of a Romanian translation of the Acceptance of Cosmetic Surgery Scale (ACSS): An examination using bifactor exploratory structural equation modelling

The Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005) is a widely used measure for the assessment of attitudes toward cosmetic surgery. Here, we examined the psychometrics of a novel Romanian translation of the ACSS. A total of 1275 Romanian adults (889 women, 386 men) completed the ACSS alongside additional, related measures. Exploratory factor analysis (EFA) with a first split-half subsample supported extraction of the original 3-factor model consisting of Intrapersonal, Social, and Consider dimensions. In a second split-half subsample, we found that a 3-factor bifactor exploratory structural equation model (B-ESEM) had superior fit compared to all alternative models that were tested. This B-ESEM representation had well-defined G-factor with adequate composite reliability, and its S-factors were also generally well-defined. Across subsamples, the optimal model showed strong or partial strong invariance across gender, with women having significantly higher latent means on the Consider factor relative to men. Evidence of convergent validity was also generally good in women, especially for the G-factor of the ACSS, but was attenuated in men. Overall, these findings indicate that the Romanian version of the ACSS has adequate psychometric properties. We also encourage scholars to consider B-ESEM representations of the ACSS in other national settings.

A Novel Scale to Assess Parental Satisfaction of Dental Local Anesthetic Techniques in Children: A Cross-Sectional Study

Background

Pain control is one of the most important aspects that can affect parental satisfaction of the dental care provided for children. Dental local anesthesia has the highest impact on pain sensation of the children. However, there is no scale in the literature to assess parental satisfaction of dental local anesthetic techniques.

Objectives

This study was aimed to assess the parental satisfaction with dental local anesthetic techniques for their children through designing a scale that reflects satisfaction and to study the validity and reliability of this scale.

Methods

A cross-sectional observational study was conducted on 150 parents (102 mothers and 48 fathers). Two techniques of local anesthesia were used for each child participated in this study (inferior alveolar nerve block and computerized intraosseous anesthesia). The developed scale consisted of 20 items in a 5-point Likert scale. Half of the items were written in a negative format. Internal consistency, validity, and factor analysis were performed in this study. Independent t-test was used to compare between the two techniques of anesthesia, between boys and girls and among fathers and mothers.

Results

Parental satisfaction mean values were higher in the computerized intraosseous anesthesia group in comparison to inferior alveolar nerve block (P value <0.05). The T-test showed that there was no difference between boys and girls regarding parental satisfaction (P value >0.05). Furthermore, fathers show lower satisfaction in the computerized interosseous anesthesia group (P value <0.05). Excellent internal consistency of this scale was resulted as Cronbach's alpha reliability coefficient was 0.985. After factor analysis, seven factor components were retained by using varimax rotation.

Conclusions

Findings of this study reported that the designed parental satisfaction of dental local anesthetic techniques scale (PSLAS) is a valid and reliable scale to be used. Moreover, this study showed that parental satisfaction was higher when computerized intraosseous anesthesia was used in comparison to inferior alveolar nerve block.

Validation of the Occupational Depression Inventory in Brazil: A study of 1612 civil servants

OBJECTIVE

The Occupational Depression Inventory (ODI) assesses work-attributed depressive symptoms. The ODI has demonstrated robust psychometric and structural properties. To date, the instrument has been validated in English, French, and Spanish. This study examined the psychometric and structural properties of the ODI's Brazilian-Portuguese version.

METHODS

The study involved 1612 civil servants employed in Brazil (M_AGE = 44, SD_AGE = 9; 60% female). The study was conducted online across all Brazilian states.

RESULTS

Exploratory structural equation modeling (ESEM) bifactor analysis indicated that the ODI meets the requirements for essential unidimensionality. The general factor accounted for 91% of the common variance extracted. We found measurement invariance to hold across sexes and age groups. Consistent with these findings, the ODI showed strong scalability (H = 0.67). The instrument's total score accurately ranked respondents on the latent dimension underlying the measure. Furthermore, the ODI exhibited excellent total-score reliability (e.g., McDonald's ω = 0.93). Occupational depression correlated negatively with work engagement and each of its components (vigor, dedication, and absorption), speaking to the ODI's criterion validity. Finally, the ODI helped clarify the issue of burnout-depression overlap. Relying on ESEM confirmatory factor analysis (CFA), we found burnout's components to correlate more strongly with occupational depression than with each other. Using a higher-order ESEM-within-CFA framework, we found a correlation of 0.95 between burnout and occupational depression.

CONCLUSION

The ODI displays robust psychometric and structural properties within the Brazilian context. The ODI constitutes a valuable resource for occupational health specialists and may help advance research on job-related distress.

Determination of the psychometric properties of the digital addiction scale for children

AIM

To determine the psychometric properties of the Digital Addiction Scale for Children.

DESIGN AND METHOD

This methodological study included 506 children aged 9-12 years. Data were collected using the child and family information form, the digital addiction scale for children and the digital game addiction scale for children. The data were evaluated using confirmatory factor analysis Cronbach's alpha, convergent validity, and gender-based measurement invariance analysis. Confirmatory factor analysis was applied using Mplus 8.7 with robust maximum likelihood estimation procedures.

RESULTS

Confirmatory factor were performed for construct validity. The scale was found to have good model fit indicators. The factor loadings of all the components were found to be >0.40. Convergent validity of Digital addiction scale for children and digital game addiction scale showed a significant positive high correlation. The total Cronbach alpha value of the scale was determined as 0.94, and the Cronbach alpha values of the subscales as Interpersonal 0.89, and Intrapersonal 0.91.

CONCLUSION

The use of the digital addiction scale for children was determined to be a valid and reliable scale for the screening of digital device use and digital addiction in a Turkish sample.

PRACTICE IMPLICATIONS

Nurses and other health professionals have an important role in detecting situations that put children's health at risk and promoting positive behaviors. It is especially important that school health nurses use valid and reliable tools that can determine children's digital addictions. Since this scale is easy and practical, it is thought that it will contribute significantly to the literature.

Defining despair: Assessing the multidimensionality of despair and its association with suicidality and substance use in early to middle adulthood

Despite considerable scientific interest in documenting growing despair among U.S. adults, far less attention has been paid to defining despair and identifying appropriate measures. Emerging perspectives from social science and psychiatry outline a comprehensive, multidimensional view of despair, inclusive of individuals' cognitive, emotional, biological and somatic, and behavioral circumstances. The current study assesses the structure and plausibility of this framework based on longitudinal data spanning early to middle adulthood. We identified 40 measures of different dimensions of despair in Wave IV (2008-2009) of the National Longitudinal Study of Adult to Adolescent Health (n = 9149). We used structural equation modeling to evaluate hypothesized relationships among observed and latent variables; we then regressed Wave V (2016-2018) suicidality, heavy drinking, marijuana use, prescription drug misuse, and illicit drug use on latent despair. Our analyses find that models for separate dimensions of despair and overall despair demonstrated excellent fit. Overall despair was a significant predictor of Wave V outcomes, especially suicidality, accounting for 20% of its variation, as compared to 1%-7% of the variation in substance use. Suicidality was consistently associated with all domains of despair; behavioral despair explained the most variation in substance use. Given these results we contend that, lacking direct measures, latent despair can be modeled using available survey items; however, some items are likely better indicators of latent dimensions of despair than others. Moreover, the association between despair and key health behaviors varies considerably, challenging its status as a mechanism simultaneously underlying increased substance use and suicide mortality in the United States. Critically, further validation of measures in other surveys can improve the operationalization of despair and its associated conceptual and theoretical frameworks, thus advancing our understanding of this concept.

Strategy and additive technologies as the catalyst for outsourcing, process innovation and operational effectiveness

PURPOSE

There is rising interest in Industry 4.0 as a factor in the competitiveness of the organization. Although many companies are aware of the importance of Industry 4.0, the development of such initiatives in Colombia is slow. Consequently, this research investigates the impact of additive technologies as part of the Industry 4.0 concept on operational effectiveness and, therefore, the competitiveness of the organization and tries to establish the factors that hinder the adequate implementation of such new, innovative technologies.

DESIGN/METHODOLOGY/APPROACH

Structural equation modeling was used to analyze the antecedents and outcomes of operational effectiveness. To this end, 946 usable questionnaires were collected from managers and personnel from Colombian organizations.

FINDINGS

Initial findings show that management is aware of Industry 4.0 concepts and implements strategies for such initiatives. Nevertheless, neither process innovation nor additive technologies have a significant impact on operational effectiveness and therefore on the competitiveness of the organization.

PRACTICAL IMPLICATIONS

The implementation of new innovative technologies requires the closure of the digital gap between urban and rural areas and between large and medium and small enterprises. Similarly, the concept of Industry 4.0 as a new, innovative manufacturing concept requires a transversal implementation to increase the competitiveness of the organization.

ORIGINALITY/VALUE

The value of this paper lies in discussing the current technological and human capabilities and strategies that Colombian organizations, as an example of a developing nation, should improve to leverage the benefits of Industry 4.0 to remain competitive. The results are probably generalizable to other regions in developing countries throughout the world.

A framework for evaluation of crowdsourcing platforms performance

This study aims to identify an appropriate conceptual framework to evaluate crowdsourcing platforms from an open innovation perspective employing a combination of qualitative and quantitative methods. The initial indices of the performance evaluation framework in the crowdsourcing platforms are obtained through the Delphi method and interviews with experts. Then, using these factors, a statistical questionnaire is designed and distributed among users of crowdsourcing platforms to confirm or reject the factors. Finally, the aspects of the performance evaluation framework of crowdsourcing platforms are specified from the perspective of open innovation. Using fuzzy hierarchical analysis, these aspects are prioritized in order of importance: Collaboration, Project design, Moderation, Terms and conditions, UI/UX (user interface and user experience), and Key statistics. Concerning the principle of crowdsourcing, which is based on crowd participation and crowd intelligence of users, Collaboration and Project design turned out to be the significant factors in evaluating a crowdsourcing platform.

Measurement invariance of the empowering and disempowering motivational climate questionnaire-coach in youth sport

The purpose of this study was to test the measurement invariance (across five languages, two time points, and two experimental conditions) of the empowering and disempowering motivational climate questionnaire-coach (EDMCQ-C; Appleton et al., 2016) when completed by 9256 young sport participants (M age = 11.53 years, SD = 1.39 years; 13.5% female). Exploratory Structural Equation Modeling was used to test the validity of a 2-factor (empowering and disempowering) model running a multiple group analysis without any equality constraint (configural invariance) followed by measurement invariance of factor loadings and thresholds (scalar invariance). Findings provided support for partial invariance across languages and scalar invariance across time and experimental groups. The factors were interpretable across the analyses, and items loaded as intended by theory except for item 15. This study provides further evidence regarding the psychometric properties of the EDMCQ-C and suggests this scale (minus item 15) can be used to provide meaningful latent mean comparisons (Marsh et al., 2013) of empowering and disempowering coach-created climates across athletes speaking the five targeted languages, across time, and across experimental groups.

Psychometric properties and measurement invariance of the Rigid and Flexible Persistence Scale in a Brazilian professional sample

Persistence involves the intention to maintain efforts when faced with obstacles and challenges, in order to achieve a specific goal. The Rigid and Flexible Persistence Scale (RFPS) is a self-report measure that assesses persistence that is theoretically derived from the premises of the Dualistic Model of Passion. The aim of the present research was to adapt the RFPS to Brazilian Portuguese and to estimate its evidence of validity and reliability in the context of work. Participants were 400 professionals, 55.8% women, aged between 18 and 68 years. The results indicate that the RFPS presented validity evidence based on the content. Corresponding to the theoretical expectations, exploratory and confirmatory factor analyses demonstrated adequacy of the structure composed of two factors, explaining 75% of the data variance, with good levels of reliability. The RFPS also revealed strong invariance across gender and work conditions (in-person vs remote). Flexible persistence showed positive association with harmonious passion and occupational self-efficacy. Conversely, rigid persistence showed positive association with obsessive passion. It was observed a mediational role of occupational self-efficacy in the relationship between harmonious passion and flexible persistence. Overall, the findings suggest that the RFPS is an adequate measure of persistence in a Brazilian occupational sample.

Investigation of psychometric properties of Turkish version of nursing students' attitudes and beliefs towards Childhood Obesity Scale

AIM

This study aimed to evaluate the Turkish psychometric properties of The Attitudes and Beliefs of Nursing Students Towards the Childhood Overweight Scale.

METHODS

The study was conducted with 219 nursing students. The data were obtained with the 'Information Form' and the 'Attitudes and Beliefs of Nursing Students Towards Childhood Overweight. Strengthening the Reporting of Observational Studies in Epidemiology guidelines was implemented in the study.

RESULT

Original scale was created using the Attitudes Towards Obese Person Scale (ATOP) and the Beliefs About Obese Persons Scale (BAOP). ATOP consists of 13 items and two sub-dimensions (self-concept, social relationships) in a 5-point Likert type that evaluates nursing students' attitudes towards childhood obesity. BAOP is 5-point Likert-type and consists of 6 items that evaluate nursing students' beliefs on childhood obesity. When the item-total score correlations were examined in the study, two items showing a negative correlation in the "ATOP" were removed. Cronbach's alpha was 0.80 for the ATOP and 0.83 for the BAOP. In the exploratory EFA and confirmatory CFA factor analyses, the factor loading of all items was >0.40 for both scales.

CONCLUSION

It was determined that Turkish psychometric properties of the Nursing Students' Attitudes and Beliefs towards Childhood Obesity Scales were valid and reliable.

A framework for assessing computational thinking skills in the physics classroom: study on cognitive test development

This study aimed to develop a computational thinking skills (CTs) assessment framework for physics learning. The framework was developed in two stages: theoretical and empirical. Furthermore, the framework was examined by developing questions, a set test instrument, in the form of multiple-choice (3 items), right-wrong answers (2 items) complex multiple-choice (2 items), and essays (15 items) for sound wave topic. There are three stage of framework examination in empirical study involving 108 students to obtain the item characteristic, 108 students for the explanatory factor analysis (EFA), and 113 students for the confirmatory factor analysis (CFA). The sample in this study was senior high school students aged 15-17 years, which were selected randomly. Theoretical study produced seven indicators for assessing CTs consisting of decomposition, redefine problems, modularity, data representation, abstraction, algorithmic design, and strategic decision-making. The empirical study proved that the items were fit to the one parameter logistic (1PL) model. Furthermore, EFA and CFA concluded that the model fits comply the unidimensional characteristics. Hence, the framework can be optimizing the measurement of students CTs in learning physics or science.

Empirical development and verification of career well-being scale for teachers in Taiwan: Implications for workplace counseling

As it is one decade since the establishment of Kidd's model, an analysis of the career well-being (CWB) experienced by Eastern workers is both timely and necessary. To this end, we conducted a series of logical investigations of CWB in Taiwanese school teachers. Study 1 was conducted to conceptualize the main features of CWB (n = 135), and Study 2 was conducted using exploratory factor analysis to determine the validity of a four-factor measurement structure (n = 191). In Study 3, tests were completed to confirm the factor structure of the CWB (n = 533). Accordingly, we established a theory-based CWB measurement approach, and statistical analysis verified the convergent, divergent, and criterion validity of our CWB measurement model. Exploratory structural equation modeling rather than confirmatory factor analysis is recommended in discussions of CWB theory and practice in educational contexts. However, because our sample solely comprised Taiwanese teachers, our results are not generalizable to other occupations or cultures, even Eastern or Chinese-derived cultures. Implications for both theory and workplace counseling practice are presented.

Psychometric Properties of the Knowledge, Attitude, and Practice Behavior of Oncology Nurses on Advance Care Planning Instrument

OBJECTIVE

Advance care planning has been practiced in Western countries for several years, but non-Western cultures face challenges in implementation. This study was dedicated to translating the instrument measure into Chinese, examining its psychometric qualities and exploring the relationships among knowledge, attitudes, and practicing behaviors in advance care planning among oncology nurses in China.

DATA SOURCES

The research adopted a cross-sectional design from September 3 to October 5, 2021. After translation and cultural adaptation, oncology nurses (N = 249) were involved. The research used psychometric evaluation to verify that the content validity, structural validity, internal consistency, and test-retest reliability enhanced the analytical rigorous instrument.

CONCLUSION

The translated and adapted instruments showed reasonable psychometric properties. The Chinese version of the KAB-ACP for oncology nurses is a consistent, valid, and reliable instrument for assessing knowledge, attitude, and practice behavior of Chinese-speaking nurses who work in advance care planning by researchers or clinicians.

IMPLICATIONS FOR NURSING PRACTICE

Measures of oncology nurses' knowledge, attitudes, and practice behaviors will allow for more targeted interventions that will improve end-of-life care outcomes.

Psychometric properties of a Greek translation of the Intuitive Eating Scale-2 (IES-2) in adults from Cyprus

The construct of intuitive eating is commonly assessed using the 23-item, 4-factor Intuitive Eating Scale-2 (IES-2; Tylka & Kroon Van Diest, 2013). In this study, we assessed the psychometric properties of a novel Greek translation of the IES-2 in adults from Cyprus. In Study 1 (N = 626), an exploratory factor analysis indicated that the IES-2 should be conceptualized as consisting of six factors that showed complete invariance across women and men. Study 2 (N = 793), using exploratory structural equation modelling (ESEM) and beifactor analysis (B-ESEM), indicated that the 6-factor B-ESEM model had adequate fit and evidenced complete invariance across sex once the correlated uniqueness of negatively worded IES-2 items was accounted for. This final model evidenced adequate composite reliability, and a global G-factor evidenced adequate convergent, concurrent, and discriminant validity. In contrast, the IES-2 S-factors showed more equivocal patterns of validity, with some S-factors showing less-than-adequate associations with body image variables, self-esteem, symptoms of disordered eating, and fruit and vegetable intake. In general, these results provide satisfactory evidence of the psychometric properties of the Greek IES-2 in adults from Cyprus, but also suggest that models of IES-2 scores may vary across national or cultural contexts.

A motivational approach to perfectionism and striving for excellence: Development of a new continuum-based scale for post-secondary students

Perfectionism has been the object of many disputes. One such debate pertains to the nature of perfectionistic strivings. Whereas perfectionistic concerns (PC) have been shown to correlate with negative outcomes, perfectionistic strivings (PS) have been associated with mixed outcomes. This view of perfectionism assumes a motivational perspective; however, commonly used questionnaires assess motivation only implicitly. To create a more explicit measure of motivation as regard perfectionism, we aimed to assess perfectionism in post-secondary education based on Deci and Ryan's self-determination continuum. We posit that introjected motivation represents the variance common to both dimensions of perfectionism. External motivation is considered to be specific to PC and identified motivation to PS. Amotivation represents a lack of meaningful striving. Intrinsic motivation, lacking perfectionism's pressure, is conceptualized to be a self-determined form of striving for excellence. We further posited that this continuum is implicitly underlain by a continuum of self-definition as defined by Blatt. The resulting questionnaire showed an adequate structure with ESEM, followed a simplex structure, and had adequate reliabilities (Study 1a/Study 2). It also showed adequate convergent validity (Study 1b/Study 2). Finally, the questionnaire proved to be invariant over a 6-week period (Study 2). Results suggest that the degree of active goal pursuit, in addition to standards setting, could be a distinguishing characteristic between dimensions of perfectionism as well as striving for excellence.

Differential Bundle Functioning of National Examinations Council Mathematics Test Items: An Exploratory Structural Equation Modeling Approach

A differential bundle function (DBF) is a situation in which examinees who are of the same ability but are from different groups are required to answer groups of items differently. DBF undermines the validity of the instrument if inadequately considered. The study examines the dimensionality of the 2017 NECO Mathematics items, determines the effect of DBF on 2017 Mathematics items concerning sex, and investigates the effect of DBF on 2017 Mathematics items concerning school ownership. This study explores Exploratory Structural Equation Modeling (ESEM), which permits the cross-loading of items that are not allowed in other models. The ex-post facto research design was adopted using secondary data, while six bundles were generated via the specification table. The population for the study comprised all 1,034,629 Senior School three students. A total of 815,104 students were selected using the simple random technique. The instrument for the study was 2017 NECO Mathematics paper three with a Cronbach's alpha of 0.82, and data were analysed using Mplus 7.4. The results revealed that the 2017 NECO Mathematics is multidimensional and items in the bundles possess construct validity as they functioned differentially to examinees' sex and school type. We recommend ESEM has a better approach to examining DBF on 2017 NECO Mathematics test items.

Impact of social influence on users' continuance intention toward sports and fitness applications

The purpose of this paper is to explore how social influence (SI), which is disaggregated into subjective norms (SN), social image (SIM), and social identity (SID), predicts perceived usefulness (PU), perceived pleasure (PP), and continuance intention (CI) toward sports and fitness applications. The underlying context is the socialization and gamification of exercise during the Covid-19 pandemic. Based on the theory of SI and the technology acceptance model, a theoretical framework was built where PU and PP mediate the influence of SI on CI, and proposed hypotheses were tested. The responses of 296 Keep users (a popular sports and fitness application in China) to a questionnaire survey were analyzed. SN and SIM were found to have significant positive effects on SID; SID has significant positive effects on PU and PP; both PU and PP have significant positive effects on the CI of users; SID and PU positively and significantly mediate the relationship between SN/SIM and CI; PU positively and significantly mediates the SID-CI relationship. However, the role of PP in mediating the influence of SI on CI is non-significant. This paper deepens the current understanding of the mechanisms that influence the relationship between SI and CI under the context of socialization and gamification services.

Bifactor exploratory structural equation modeling: A meta-analytic review of model fit

Multivariate behavioral research often focuses on latent constructs-such as motivation, self-concept, or wellbeing-that cannot be directly observed. Typically, these latent constructs are measured with items in standardized instruments. To test the factorial structure and multidimensionality of latent constructs in educational and psychological research, Morin et al. (2016a) proposed bifactor exploratory structural equation modeling (B-ESEM). This meta-analytic review (158 studies, k = 308, N = 778,624) aimed to estimate the extent to which B-ESEM model fit differs from other model representations, including confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), hierarchical CFA, hierarchical ESEM, and bifactor-CFA. The study domains included learning and instruction, motivation and emotion, self and identity, depression and wellbeing, and interpersonal relations. The meta-analyzed fit indices were the χ2 /df ratio, the comparative fit index (CFI), the Tucker-Lewis index (TLI), the root mean square error of approximation (RMSEA), and the standardized root mean squared residual (SRMR). The findings of this meta-analytic review indicate that the B-ESEM model fit is superior to the fit of reference models. Furthermore, the results suggest that model fit is sensitive to sample size, item number, and the number of specific and general factors in a model.

Dark personality traits and entrepreneurial intentions among Pakistani university students: The role of executive functions and academic intent to entrepreneurship

This study examined the mediating role of core Executive Functions (EF: working memory and inhibitory control) and moderating role of Perceived Academic Intent to Entrepreneurship (PAIE) in relationship between Dark Personality Traits (SDT) and Entrepreneurial Intentions (EI) of university students. A sample of 539 university students enrolled in various undergraduate and postgraduate programs completed the Short Dark Triad-3 (SD3), Adult Executive Functioning Inventory (ADEXI), and measures for assessing Entrepreneurial Intent and Perceived Academic Intent to Entrepreneurship. The results showed that of SDT, only Machiavellianism was significantly associated with EI. Both of the core executive functions and PAIE were also positively correlated with EI. Moreover, findings showed that EF positively mediated the relationship between Machiavellian disposition and entrepreneurial intention, while perceived academic intent to entrepreneurship moderated the relationship between executive functions and EI. A significant moderated mediation index was also reported. Findings offer useful insight to the interplay among above mentioned variables and guide educational and organizational psychologists to employ core cognitive strategies for promoting entrepreneurial thoughts and channelizing the productive energies of students with malevolent tendencies through academic coaching.

Assessing Teaching Effectiveness in Blended Learning Methodologies: Validity and Reliability of an Instrument with Behavioral Anchored Rating Scales

The evaluation of teaching effectiveness in blended learning methodologies is usually carried out using Likert-type questionnaires; however, instruments with Behavioral Anchored Rating Scales (BARS) are sometimes employed for this purpose. This paper examines the validity and reliability of an instrument with BARS designed to assess teaching effectiveness in blended learning environments, within the university setting. The research involves a sample of 1436 students from a medium size university in Spain. Using this sample (n = 1436), the authors carry out a psychometric study that consists of four phases: (1) comprehension validity analysis, (2) construct validity analysis, (3) confirmation of construct validity, and (4) analysis of the instrument reliability. The findings provide satisfactory values for all the parameters analyzed (for instance: Variance explained = 77.61%; RMSEA = 0.042; or Cronbach's alpha = 0.956), indicating that the BARS instrument examined is perfectly valid and reliable for the appraisal of teaching effectiveness in blended learning methodologies. The authors conclude that this paper fills an important gap in the literature by presenting an instrument that, thanks to the use of behavioral scales, facilitates this task in the university context.

The Body and Appearance Self-Conscious Emotions Scale (BASES): A comprehensive examination of its factorial validity, with recommendations for researchers

The 16-item Body and Appearance Self-Conscious Emotions Scale (BASES) is widely used to assess the discrete emotions of guilt, shame, authentic pride, and hubristic pride. However, recent work has questioned the factorial validity of the BASES (i.e., the extent to which it truly assesses a discrete set of self-conscious emotions). In the present study, we re-assessed the factorial validity of the BASES using confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM). An online sample of adults from the United Kingdom (N = 637) were asked to complete the BASES. Our analyses indicated that the original 4-factor CFA model had adequate fit but resulted in very high latent correlations between similarly valenced facets (Guilt/Shame and Authentic/Hubristic Pride, respectively). An alternative 2-factor CFA model (combining Guilt-Shame and Authentic-Hubristic Pride) had a less-than-ideal fit. Conversely, 4-factor and 2-factor ESEM solutions both resulted in a superior fit to the data than their CFA counterparts, and in reduced estimates of factor correlations. Both of these ESEM solutions were also fully invariant across gender. These results have important theoretical and practical implications for our understanding of body and appearance-related self-conscious emotions and how this construct is currently measured.

Dimensionality analysis of the German version of the Screen for Cognitive Impairment in Psychiatry (SCIP-G)

Background

Psychiatric disorders, especially schizophrenia, are characterised by cognitive impairment. The rapid detection of cognitive dysfunction - also in the course of the disease - is of great importance. The Screen for Cognitive Impairment in Psychiatry (SCIP) was developed to provide screening of psychiatric patients in clinical practice and is available in several languages. Prior psychometric investigations into the dimensionality of the SCIP have produced two different models: a one-factor model assumes that the five subscales of the SCIP load together, whereas an alternative model suggests that the subscales load on two factors, namely verbal memory and processing speed. We carried out a confirmatory factor analysis of the German version of the SCIP (SCIP-G).

Methods

323 patients with psychotic, bipolar affective, and depressive disorders were studied.

Results

The one-factor approach did not yield an acceptable model fit (chi-squared test: χ² = 109.5, df = 5, p < 0.001, χ²/df = 21.9). A two-factor solution, with the subtests Verbal Learning Test-Immediate Recall, Delayed Recall Test of the VLT, and Working Memory Test loading on the first factor, whereas the subtests Verbal Fluency Test and Psychomotor Speed Test loading on the second factor, obtained a good model fit (χ² = 6.7, df = 3, p = 0.08, χ²/df = 2.2).

Conclusions

These data show that a good model fit can be achieved with a two-factor solution for the SCIP. This study is the first to conduct a confirmatory factor analysis using the German SCIP version and to test its dimensional structure using a hypothesis-testing approach.

The concept of pain inventory for children: The reliability and validity study of the Turkish version

BACKGROUND AND PURPOSE

Pain experiences in childhood are very likely to be reflected in adulthood. The early evaluation of the concept of pain in children may eventually lead to. better patient outcomes in the future. Therefore, we aimed to culturally and developmentally adapt the Concept of Pain Inventory for Children (COPI) for Turkish children.

METHODS

This descriptive, correlational study was conducted with 239 post-operative children aged 8-12 years between June and December 2021. The research adhered to COSMIN guidelines. The data were collected using a descriptive information form and the COPI. Factor analysis, Cronbach's alpha, and item-total score analysis were used for the data analysis.

RESULTS

The resulting unidimensional scale consists of 12 items in Turkish. The scale explained 65% of the total variance. The exploratory factor analysis showed that the factor loadings of items ranged from 0.64 to 0.91. The confirmatory factor analysis showed that the factor loadings of items ranged from 0.66 to 0.92. Goodness of fit indexes were found to be as follows: Normed Fit Index >0.90; Incremental Fit Index >0.90; Comparative Fit Index >0.90; and the Root Mean Square Error of Approximation <0.08. The total Cronbach's alpha coefficient of the scale was 0.78 (reliable).

CONCLUSIONS

The 12-item Turkish translation of the COPI was deemed valid and reliable in 8-12-year-old children in a post-operative setting.

PRACTICE IMPLICATIONS

Evaluation of children's pain concepts during childhood may contribute to the identification of conceptual gaps for pain science education.

Ergonomic Factors That Impact Job Satisfaction and Occupational Health during the SARS-CoV-2 Pandemic Based on a Structural Equation Model: A Cross-Sectional Exploratory Analysis of University Workers

This paper presents a structural equation model to determine the job satisfaction and occupational health impacts concerning organizational and physical ergonomics, using (as a study) objective unionized workers from the University of Sonora, South Campus, as an educational enterprise, during the SARS-CoV-2 pandemic. The above is a key element of an organizational sustainability framework. In fact, there exists a knowledge gap about the relationship between diverse ergonomic factors, job satisfaction, and occupational health, in the educational institution's context. The method used was a stratified sample of workers to which a job satisfaction-occupational health questionnaire was applied, consisting of 31 items with three-dimensional variables. As a result, the overall Cronbach's Alpha coefficient was determined, 0.9028, which is considered adequate to guarantee reliability (i.e., very high magnitude). Therefore, after the structural equation model, only 12 items presented a strong correlation, with a good model fit of 0.036 based on the root mean square error of approximation, 1.09 degrees of freedom for the chi-square, 0.9 for the goodness of fit index, and a confidence level of 95%. Organizational and physical factors have positive impacts on job satisfaction with factor loads of 0.37 and 0.53, respectively, and p-values of 0.016 and 0.000, respectively. The constructs related to occupational health that are considered less important by the workers were also determined, which would imply a mitigation strategy. The results contribute to the body of knowledge concerning the ergonomic dimensions mentioned and support organizational sustainability improvements in educational institutions and other sectors.

Psychometric Evaluation of the Cooper-Norcross Inventory of Preferences-Therapist Version

The Cooper-Norcross Inventory of Preferences (C-NIP) is a commonly used and psychometrically validated measure of client preferences in therapy. However, the C-NIP version for therapists (C-NIP-T) has not yet been validated. This study aimed to develop a Chinese version of the C-NIP-T and test its factor structure, reliability, and concurrent validity. A national sample of 1,054 Chinese mental health professionals completed the C-NIP-T and provided relevant demographic information. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used to examine the factor structure of the C-NIP-T. ESEM provided stronger evidence than CFA for the hypothesized four-factor model. Internal consistency coefficients (Cronbach's α) of the four subscales ranged between .60 and .76. Full or partial scalar invariance was established across therapists' therapeutic orientations, gender, personal therapy, and clinical experience. There were significant differences in subscale scores among therapists who identified as cognitive/cognitive-behavioral, psychoanalytic/psychodynamic, and humanistic/client-centered, supporting the concurrent validity of the C-NIP-T. The C-NIP-T is a psychometrically sound measure that can be used to assess therapists' preferences about therapy.

The Inventory of Complicated Grief-A Systematic Psychometric Review and Conceptual Replication Study of the Structural Validity

The Inventory of Complicated Grief (ICG) is a commonly used self-report measure in psycho-oncology, best supportive care, and palliative medicine. However, existing validation studies yielded conflicting results regarding the structural validity. This study provides a psychometric review and conceptual replication of the ICG latent structure to test the hypothesis that existing studies overfit unreliable sources of variance, which overshadow the unidimensionality of the ICG. All proposed latent models identified in the psychometric review were tested in a series of confirmatory and exploratory structural equation models. Specifically, at least five to six latent intercorrelated factors were necessary to reach acceptable model fit. However, a general CG factor accounted for most variance and ICG sum scores showed predictable associations with anxiety and depressive symptoms, which suggests that the ICG is essentially unidimensional. There are indications that other measures of pathological grief show similar inconsistencies. Overall, potentially emerging subfacets of the ICG should not be interpreted as distinct "symptom clusters." If time constraints are an issue as is often the case in clinical research, complicated grief may just be measured by a reduced item set without a significant loss of information or complexity.

How Accurate Is Your Correlation? Different Methods Derive Different Results and Different Interpretations

Assessing the association between conceptual constructs are at the heart of quantitative research in educational and psychological research. Researchers apply different methods to the data to obtain results about the correlation between a set of variables. However, the question remains, how accurate are the results of the correlation obtained from these methods? Although various considerations should be taken to ensure accurate results, we focus on the types of analysis researchers apply to the data and discuss three methods most researchers use to obtain results about correlation. Particularly, we show how correlation results in bivariate correlation, confirmatory factor analysis (CFA), and exploratory structural equation modeling (ESEM) differ substantially in size. We observe that methods that assume independence of the items often generate inflated factor correlations whereas methods that relax this assumption present uninflated, thus more accurate correlations. Because factor correlations are inflated in bivariate correlation and CFA, the discriminant validity of the constructs is often unattainable. In these methods, the size of the correlation can be very large and biased. We discuss the reasons for this variation and suggest the type of correlation that researchers should select and report.

Development of a histopathological index for skeletal muscle analysis in Rattus norvegicus (Rodentia: Muridae)

Skeletal muscle histopathological changes induced or caused by pathologies in animal models, can impair functionality, being the main focus of therapeutic studies. This study aimed to propose a histopathological index to assess, in a quantitative manner, skeletal muscle changes induced by experimental protocols for Rodentia's models. For the development, evaluation of fit and parsimony, replicability, and sensitivity index, Wistar rats from experiments with the same experimental design, but with different variation factors, were used to achieve different levels of damage. The anterior tibial muscle of these animals was collected, processed histologically, and stained with hematoxylin and eosin. The adjustment and parsimony of the index were availed through Confirmatory Factor Analysis, reproducibility for evaluation of three people trained through the Intra-Class Correlation, and the discrimination capacity through a one-way ANOVA Test. We pointed out the adjustment for the proposed index while the ICC showed high reproducibility (n = 56; k = 3; ICC = 0.9790) and differences in the extent of damage between groups, following the hierarchical association promoted by experimental model stresses. The results show that the proposed index has a good fit and parsimony (χ² = 426.34; p < 0.0001), in addition to being easily replicable by other researchers who know the morphology of muscle tissue and its morphological changes. It is worth mentioning that the development of tools that facilitate histopathological analysis, and that can quantitatively express the findings, are of great importance for the studies of regenerative science, reinforcing the relevance of this study.
