VISCERAL SENSITIVITY INDEX (VSI-IT): Italian Adaptation and Validation

The Visceral Sensitivity Index (VSI) represents a significant advancement in the assessment of gastrointestinal-specific anxiety among patients with irritable bowel syndrome (IBS) and chronic inflammatory bowel diseases (IBD)—such as ulcerative colitis and Crohn’s disease. However, an Italian version of the instrument is not yet available for the Italian-speaking population. This study utilized a national sample of 500 individuals divided into four groups: (a) patients with Crohn’s disease, (b) patients with ulcerative colitis, (c) patients with IBS, and (d) healthy controls (individuals without any diagnoses) to test the validity and reliability of the Italian VSI. Using back-translation methodology to ensure translation fidelity, this research applied a questionnaire and the VSI through an online format to 500 participants. Confirmatory Factor Analysis (CFA) revealed that the Italian VSI had excellent psychometric properties, demonstrating high internal consistency (Cronbach’s α = 0.949) and construct validity. The scale proved sensitive in detecting significant differences in visceral sensitivity among groups, highlighting its utility as a clinical and research assessment tool. Specifically, the Italian VSI exhibited a unidimensional factorial structure and maintained a strong correlation with interoceptive awareness, type of disease, and gastrointestinal symptom severity, confirming its role in enhancing the understanding and management of IBD and IBS in Italy.

Adaptation and Validation of the Post-Pandemic Health Promotion Behavior of Young Adults in the Digital Age (PS-SGD) Scale in the Turkish Population.

Young adulthood is a critical developmental period in which individuals establish life-long health behaviors and take responsibility for their own health care. Health promotion strategies tailored to young adults, leveraging digital tools, and addressing challenges exacerbated by events like the COVID-19 pandemic are needed. The aim of this study was to adapt the post-pandemic health promotion behavior of young adults in the digital age (PS-SGD) scale to the Turkish population in order to assess and compare the health behavior of young adults after the pandemic. A total of 312 participants, aged between 19 and 29 years, were included in the study via non-probabilistic criterion sampling, while the Turkish adaptation process started with translation and back translation methods performed with three language and two health science experts. For statistical analysis, EFA and CFA were conducted to evaluate internal consistency and structural validity. Confirmatory factor analysis was utilized to confirm the structure of the six sub-dimensions. Additionally, measurement invariance was examined regarding participants' gender to determine if the scale accurately captured similar traits across diverse groups. The relationship between the test-retest data was tested by Pearson correlation to measure consistency and its invariance over time. The gender distribution of the sample was found to be 61.3% female and 38.7% male. According to the results of EFA, items 8 and 18 were removed from the Turkish-adapted version. As a result of the reliability analysis conducted with the Turkish version of the scale, the Cronbach alpha coefficient was obtained as 0.851 for the post-pandemic health promotion behavior. Additionally, the scale was rated as reliable with the following Cronbach alpha values: 0.79 for the "personal hygiene", 0.78 for "dietary habits", 0.72 for "using mobile devices", 0.70 for "emotional health", 0.68 for "health care and physical activity", and 0.51 for "social health" sub-dimensions. To examine the six sub-dimension factor structures of the scale, fit indices were calculated as χ2/df (1.722), GFI (0.894), IFI (0.908), TLI (0.892), CFI (0.907), RMSEA (0.048), and SRMR (0.057) and were within acceptable limits. Findings of the multi-group confirmatory factor analysis for measurement invariance were less than or equal to 0.01 for the ∆CFI and ∆RMSEA values across all indices. 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, while test-retest results showed a high positive correlation. The Turkish version of the post-pandemic health promotion behavior scale of young adults in the digital age scale, consisting of 25 items and six subscales, was proven to be a valid and reliable tool to measure health promotion behavior in young adults aged 19-29 years.

The peer mental health stigmatization scale-revised (PMHSS-R): Psychometric properties and cross-cultural factorial invariance in university students in Ireland and Argentina.

The study aimed to assess the psychometric quality of the Peer Mental Health Stigmatization Scale - Revised (PMHSS-R), by examining its factorial structure among young adults in Ireland and Argentina. A total of 429 participants aged between 18 and 25 years old were recruited (n = 187 Ireland, n = 242 Argentina). The PMHSS-R was completed by Irish participants and was translated, pilot-studied, and subsequently completed by Argentinian participants. A Confirmatory Factor Analysis demonstrated optimal factor loadings for an eight-item solution and acceptable internal consistency for both scale dimensions in the Argentinian sample. Satisfactory levels of partial scalar invariance were achieved between countries, indicating that the scale measures mental health stigma consistently across cultures. Our findings highlight the PMHSS-R as a cross-culturally valid and reliable psychometric instrument to evaluate interventions targeting stigma. In conclusion, the PMHSS-R can be used in cross-cultural research to compare levels of mental health stigma and investigate the interplay between stigma and other psychologically relevant constructs between different countries and cultural contexts.

Direct retrospective measurement of therapeutic changes: an example using the Czech version of the Questionnaire of Personal Changes (Q-PC)

Objective: The study aimed to test the psychometric properties of the Czech translation of the Questionnaire of Personal Changes (Q-PC), a measure designed for retrospective (direct) measurement of change in psychotherapy. Methods: A sample of group psychotherapy clients (N = 222) and a nonclinical sample (N = 167) sample were used. Clients in the clinical sample were administered the Q-PC in addition to several pre–post outcome measures. Confirmatory factor analysis, correlational analysis, and structural equation modeling were used to test the Q-PC’s factor structure, longitudinal measurement invariance, reliability, convergent validity, sensitivity to change, and other psychometric properties. Results: The Q-PC demonstrated a unidimensional structure that was strictly invariant between two follow-up measurement waves. The measure also demonstrated excellent reliability and sensitivity to change and good convergent validity. Furthermore, it demonstrated a similar relationship to baseline severity as the pre–post outcome measures. Conclusions: The retrospective measurement of change is a promising approach that has the potential to complement the traditional pre–post measurement of change.

Psychometric validation of the Montgomery–åsberg Depression Rating Scale – Youth (MADRS-Y) in a clinical sample

Background Depression in adolescence is a serious major global health problem with increasing rates of prevalence. Measures of depression that are valid for young people are clearly needed in clinical contexts. Methods The study included 577 patients from child and adolescent psychiatry (n = 471) and primary care (n = 106) aged 12–22 years in Sweden (Mage=16.7 years; 76% female). The reliability and validity for Montgomery–Åsberg Depression Rating Scale – Youth (MADRS-Y) were investigated. To confirm the latent structure, we used a single-factor confirmatory factor analysis (CFA). A Kruskal–Wallis test was performed to test total score differences between diagnostic groups. Using Spearman’s rho correlations, we examine whether single items in the MADRS-Y correlate with suicidal ideation measured by The Suicidal Ideation Questionnaire-JR (SIQ-JR). Results The internal consistency using McDonald’s coefficient omega was excellent. The CFA of the 12-item MADRS-Y supported a one factor structure. Evidence of convergent and discriminant validity was shown. There was a significant difference in MADRS-Y scores across diagnostic groups, with higher results for depressive disorders. A strong correlation with suicidal ideation was found for two items. Conclusions The results support MADRS-Y as a brief, reliable, and valid self-report questionnaire of depressive symptoms for young patients in a clinical setting.

Results: The Q-PC demonstrated a unidimensional structure that was strictly invariant between two follow-up measurement waves. The measure also demonstrated excellent reliability and sensitivity to change and good convergent validity. Furthermore, it demonstrated a similar relationship to baseline severity as the pre–post outcome measures. Conclusions: The retrospective measurement of change is a promising approach that has the potential to complement the traditional pre–post measurement of change.

Translation, transcultural adaptation, and convergent validity of the Arabic version of the Mukbang addiction scale

IntroductionThe present study evaluated the psychometric properties of the Arabic translation of the Mukbang Addiction Scale (MAS) among Arabic-speaking adults from the general population. Specifically, it aimed to assess the factorial structure through a confirmatory factor analysis, determine the composite reliability through Cronbach alpha and McDonald’s omega scores, assess gender invariance, and evaluate the convergent validity by examining its correlation to eating addiction and psychological distress.MethodsA total of 370 individuals with a mean age of 21.94 ± 2.29 years participated in this study, which was conducted using an online platform. The participants were surveyed on demographic information, mukbang addiction, food addiction, and psychological distress. Translation was conducted using the forward and backward technique.ResultsThe findings demonstrated excellent internal consistency of the Arabic MAS (McDonald’s omega coefficient = 0.93). Confirmatory factor analyses validated the one-factor structure of the scale, while establishing measurement invariance across sex at the configural, metric, and scalar levels. No sex differences were observed in the Mukbang addiction levels. Lastly, the MAS scores were significantly and positively correlated with food addiction and psychological distress, supporting their convergent validity.ConclusionThe current research provides evidence supporting the reliability and validity of the Arabic version of the MAS as a self-report method for assessing addictive Mukbang watching. While further validations are needed to corroborate the present findings, this measure can be effectively utilized across different fields, including schools, mental health centers, and researchers aiming to understand this global phenomenon.Plain English SummaryMukbang refers to individuals or hosts consuming large quantities of food while interacting with their audiences through recorded video or a live stream. The Mukbang phenomenon has gained substantial popularity among young individuals over the past years, rising concerns about its potential impact on their eating habits and health, especially when overconsumed. Overconsumption of mukbang content, or Mukbang addiction, aligns with the core features of addiction, including compulsive engagement, tolerance, and withdrawal symptoms, making it comparable to other addictive behaviors. Mukbang addiction can lead to detrimental effects on mental and physical health, including neglect of balanced nutrition, disordered eating habits, obesity, feelings of guilt, shame, poor self-esteem, distorted self-images, body dissatisfaction, heightened anxiety or depression, and social isolation. Given these significant impacts, valid and reliable tools are crucial to enable an accurate assessment of Mukbang addiction. This study proposes to translate, adapt and examine the psychometric properties of the Mukbang Addiction Scale (MAS) in a sample of Arabic-speaking individuals from the general population. Findings showed that the six MAS items loaded on a single factor with strong internal consistency and good convergent validity, preliminarily indicating its potential validity and reliability for assessing addictive mukbang-watching among Arabic-speaking individuals.

Novel measures of cognition and function for the AD spectrum in the Novel Measures for Alzheimer's Disease Prevention Trials (NoMAD) project: Psychometric properties, convergent validation, and contrasts with established measures.

This study derived composite scores for two novel cognitive measures, the No Practice Effect (NPE) battery and the Miami Computerized Functional Skills Assessment and Training system for use in early-stage Alzheimer's disease (AD) clinical trials. Their psychometric properties and associations with AD risk markers were compared to those of well-established measures. For 291 older adults with healthy cognition or early mild cognitive impairment, Exploratory factor analyses were used to identify the factor structure of the NPE. Factor and total scores were examined for their psychometric properties and associations with AD risk biomarkers. Composite scores from the novel cognitive and functional measures demonstrated better psychometric properties (distribution and test-retest reliability) and stronger associations with AD-related demographic, genetic, and brain risk markers than well-established measures, DISCUSSION: These novel measures have potential for use as primary cognitive and functional outcomes in early-stage AD clinical trials. Well-established cognitive tests may not accurately detect subtle cognitive changes. No Practice Effect (NPE) and Computerized Functional Skills Assessment and Training are novel measures designed to have improved psychometric properties. NPE had Executive Function, Cognitive Control/Speed, and Episodic Memory domains. Novel measures had better psychometric properties compared to established measures. Significant associations with Alzheimer's disease biomarkers were found with novel measures.

Modification of a parent-report sleep scale for individuals with CDKL5 deficiency disorder: a psychometric study.

Sleep difficulties are common in CDKL5 deficiency disorder (CDD), a developmental and epileptic encephalopathy (DEE). This study evaluated the factor structure of the Disorders of Initiating and Maintaining Sleep (DIMS), Disorders of Excessive Daytime Somnolence (DOES) and Sleep Breathing Disorders (SBD) domains of the Sleep Disturbance Scale for Children (SDSC) for CDD. A cross-sectional psychometric study design was used. Data were collected for 125 individuals aged 3 years or older who attended a US Centers of Excellence clinic or registered with the International CDKL5 Disorder Database. The median age was 10.3 years (range 3.2 - 40.7 years) and 105 (84%) were female. Two of the three SBD items related were not observed by most respondents and analysis was restricted to the DIMS and DOES domains. Using all items in the initial confirmatory factor analysis, two items in the DIMS domain and one item in the DOES domain loaded poorly. After deleting these items and repeating the analysis, item loading (0.524-0.814) and internal consistency (DIMS: 0.78, DOES: 0.76) statistics were good. The square of the inter-domain correlation coefficient was 0.17, less than Average Variance Extracted values for both domains and indicating good discriminant validity. The Tucker-Lewis and Comparative Fit indices were slightly lower than the threshold of >0.9 for establishing goodness of fit. The modified DIMS and DOES domains from the SDSC could be suitable clinical outcome assessments of insomnia and related impairments in CDD and potentially other DEE conditions.

The Spanish Version of the Sussex-Oxford Compassion for Others Scale (SOCS–O) in Nursing Students: Psychometric Properties and Its Relation with Mindfulness

Abstract Objectives This study aimed to examine the psychometric properties of the Sussex-Oxford Compassion for Others Scale (SOCS–O) in a large sample of Spanish undergraduate nursing students. Method After a forward–backward translation process, we conducted a cross-sectional study among nursing students in their first year of training at two Spanish universities. The mean age of the participants (n = 683) was 22.74 years old, and 83.46% were women. Together with compassion for others, mindfulness was also assessed. Results Descriptive results revealed high scores across all dimensions of the SOCS–O. The data supported a 3-factor structure with correlated factors (χ2(167) = 363.47, p < 0.01; CFI = 0.96; TLI = 0.95; RMSEA = 0.05, 90% CI = 0.04, 0.05; SRMR = 0.04). Reliability estimates, measured by Cronbach’s alpha, were excellent, ranging from 0.87 to 0.93. Measurement invariance across gender was confirmed. Men exhibited significantly lower levels in all compassion dimensions: Recognizing suffering (mean difference = − 0.40), Understanding the universality of suffering (mean difference = − 0.33), and Behavioral compassion (mean difference = − 0.57) (all p < 0.01). The structural equation model showed a clear relationship between mindfulness and compassion (χ2(581) = 1345.79, p < 0.01; CFI = 0.92; TLI = 0.92; RMSEA = 0.04, 90% CI = 0.04, 0.04; SRMR = 0.06). Conclusions The findings showed that the Spanish version of the SOCS–O has robust psychometric properties. The SOCS–O is a reliable tool for measuring compassion with three subscales and helps advance understanding of compassion among student nurses. The positive relationship between mindfulness and compassion suggests that incorporating mindfulness training into nursing curricula could enhance the delivery of compassionate care.

P-458 Development and validation of the fertility lifestyle assessment scale

Abstract Study question Can the development of the “Fertility Lifestyle Assessment Scale” contribute to the evaluation of person lifestyle habits related to fertility? Summary answer The development of the Fertility Healthy Lifestyle Assessment Scale will contribute to the evaluation of person lifestyle habits related to fertility. What is known already Healthy lifestyle habits are important for preparing the body and reproductive hormones for the demands of conception. Malnutrition, overeating, smoking, sedentary life, stress, sleep deprivation etc., situations all represent unhealthy lifestyles. The individuals may also preserve and increase fertility potential by modifying their lifestyles. Despite wide evidence about the benefits of healthy lifestyle for individuals with fertility problems, lifestyle is not systematically evaluated in generally fertility clinics. Current in study aimed to develop a valid and reliable measurement tool in order to determine risky lifestyle behaviors that may contribute to the development of fertility problems of individuals. Study design, size, duration A methodological study was conducted between July 2020- December 2021. An item pool (123 items) was prepared by reviewing the literature and the opinions of researchers and fertility experts. A multidisciplinary team of doctor, nurses and patient collaborated to asses suitability of each item of Fertility Lifestyle Assesment Scale. The Item Content Validity Index varied between .80 and 1.00. As a result a final 46-item Fertility Lifestyle Assessment Scale was developed. Participants/materials, setting, methods Participants (a) who can speak, read and write Turkish; (b) 18 years of age or older; married/single women or men, (c) who have not yet had children, and (d) who are considering having children in the future were included. The sample of this study consisted of 526 participants who met the inclusion criteria and agreed to be a part of the present study. Main results and the role of chance In the exploratory factor analysis (EFA), the Kaiser-Meyer-Olkin (KMO) coefficient of 46 items was .865 and the result of Bartlett’s sphericity test was χ2 = 15265.707, p < .001. As a result of EFA, it was determined that the scale consisted of seven subscale. Also, seven subscales were exposed to explanatory analysis: “emotional well-being”, “physical activity”, “sleep quality”, “nutrition”, “clothing/hygiene”, “use of technology”, “spiritual dimension”. These seven subscales explained 71.25% of the total variance, which shows the power of the factor structure of the scale. The total Cronbach’s alpha was .87. The item-total score correlation coefficients ranged between .19 and .57. The Pearson correlation coefficients between subscale scores and scale total scores were between .21 and .98. The Cronbach’s alpha coefficients of the subscales ranged from .60 to .98. According to the Spearman–Brown analysis, the split-half correlation coefficient was .898. Item scores were different from each other (Hotelling’s T2 = 1189.347, p= .000). This scale is valid and reliable for measuring the healthy lifestyle for improving fertility of women and man who unmaried. Limitations, reasons for caution The limitation of the study was that only 3/1 of the sample to which the scale was applied was composed of men. Wider implications of the findings This scale can be used to evaluate fertility-related lifestyle factors in individuals who are considering getting pregnant starting from the preconceptional period or who have fertility problems and apply for treatment. The scale may be easily performed by healthcare professionals and may contribute to improve fertility. Trial registration number Not applicable

Learning mathematics with personal mobile devices in school: a multigroup invariance analysis of acceptance among students and teachers

Students’ use of personal mobile devices (PMDs), including smartphones, tablets, and laptops, in mathematics classrooms globally has become feasible due to the implementation of the bring your own device (BYOD) initiatives and policies in schools. Students’ academic use of PMDs in mathematics learning has been associated with increased motivation, enjoyment, and enhanced performance. While debates continue worldwide on the bans of PMDs in schools, it is noteworthy that students in Namibian basic education are not permitted to use PMDs in schools. This study employed a comparative nonexperimental quantitative research design to assess the perceived usefulness (PU) and behavioural intention (BI) to use PMDs in mathematics classrooms among 500 Namibian students and 209 teachers. The study employed a volunteer purposeful sampling method to select participating students and teachers from government schools in the Omusati and Khomas regions. Student selection was based on self-selection from full-class mathematics groups. Similarly, the study utilised volunteer purposeful sampling to recruit grades 4–12 mathematics teachers. Utilising structural equation modelling, the findings revealed that students expressed more positive ratings for PMD usefulness and intention than did teachers. Furthermore, PU significantly predicted students’ BI to learn mathematics with PMDs in school. Multigroup confirmatory factor analysis supported configural, metric, and scalar invariance in PU and BI factor structures across both participant groups. However, when students’ latent means of PU and BI are set to 0, the teachers’ latent mean parameter estimates are negative, suggesting potential disparities. Teachers should recognise and leverage students’ positive perceptions of PMDs to enhance motivation and engagement in mathematics learning. Simultaneously, ensuring consistent assessment across participant groups is essential, while addressing teachers’ PMDs reservations through professional development and support remains crucial.

Validation of the Centrality of Religiosity Scale for the Portuguese Population.

The main aim of this study was to validate and adapt the Centrality of Religiosity Scale to the Portuguese population. A total of 1018 subjects participated in this study. The metric qualities demonstrated in the analyses suggested that the factor structure was based on five dimensions identical to those proposed by its authors. After analysing its psychometric qualities, we concluded that this instrument can be applied to the Portuguese population and is a valuable tool in studies related to the psychology of religion and spirituality.

Factorial invariance of the Wechsler Intelligence Scale for Children, Fifth Edition, across the UK, US and Australia & New Zealand.

This study examined the factorial invariance of the factor structure of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) across the UK, US and Australia & New Zealand (A&NZ). The factorial equivalence of cognitive assessments should be demonstrated before assuming cross-culture generalizability and interpretations of score comparisons. Data were obtained from the UK, US and A&NZ normative standardizations of the WISC-V. The samples consisted of 415 UK, 2200 US and 528 A&NZ children, aged 6-16. Confirmatory factor analysis was applied separately in each sample to establish the baseline model. Next, tests of factorial invariance were undertaken using the recommended hierarchical approach, firstly across the UK and A&NZ samples and then across the UK and US samples. The five-factor first-order scoring model was found to be excellent fit across all three samples independently. Strict factorial invariance of the WISC-V was demonstrated firstly across the UK and A&NZ and secondly the UK and US nationally representative standardization samples. Comparison of latent means found small but significant differences in female children across the UK and A&NZ samples. Consistent with previous research, these results demonstrate the generality of the WISC-V factor structure across the UK, US and A&NZ. Furthermore, as the WISC-V factor structure aligns with the Cattell-Horn-Carroll (CHC) model of cognitive abilities, the results add further support to the cross-cultural generalizability of the CHC model. Small but significant differences in latent factor scores found across samples support the development and use of local normative data.

Designing and Validating a Comprehensive Patient-Reported Outcomes Measure for Ambulatory Cancer Settings: The Revised Edmonton Symptom Assessment System for Cancer.

Patient-reported outcomes (PROs) information has been routinely collected in Cancer Care Alberta (CCA) for years using the revised Edmonton Symptom Assessment System (ESAS-r) and Canadian Problem Checklist (CPC). There was interest in combining these into a more comprehensive single measure tailored to ambulatory cancer settings. The purpose of this study was to validate an expanded and redesigned ESAS-r called the ESAS-r Cancer. Stakeholder engagement, a review of the literature, and 2 years of CPC data collected in the cancer program informed the addition of six symptoms to the ESAS-r. To assess and validate the measure, 1,600 randomly sampled patients were mailed paper copies of the ESAS-r Cancer, ESAS-r, and a validated, comprehensive PRO measure called the Memorial System Assessment Scale-Short Form (MSAS-SF), which is often used with patients with cancer. Canonical Correlation Analysis and exploratory factor analyses were performed to assess concurrent and construct validity of the ESAS-r Cancer against ESAS-r, using MSAS-SF as the reference measure for comparison. Cronbach α was calculated to assess reliability. Four hundred and sixty-one patients (29% response rate) completed all three questionnaires. ESAS-r Cancer showed higher numerical correlation than ESAS-r and accounted for more information included on MSAS-SF, explaining slightly more variance than ESAS-r (75.2% v 73.5%). The three-dimensional factor structure of ESAS-r Cancer outperformed the two-dimensional factor structure of ESAS-r. The reliability of ESAS-r Cancer was verified and found to be slightly higher than ESAS-r (Cronbach α = .903 v .884). ESAS-r Cancer is now in use with patients throughout CCA. This valid and reliable PRO measure can be used by other cancer or specialized health care programs who wish to routinely assess common symptoms.

Factor structure of FUNDES-Child-SE measuring the participation and independence of children with disabilities.

FUNDES-Child-SE is a proxy rating questionnaire for measuring participation and independence in children with disabilities in a Swedish context. It includes the components of frequency of attendance, engagement and independence. The original, Taiwanese FUNDES-Child 7.0, has previously been found to have a four-factor structure for frequency of participation and a two-factor structure for independence. The aim of this study was to test the factor structure in FUNDES-Child-SE. The factor structure is an important part of construct validity. Caregivers of 163 children with disabilities aged 6-18 years participated in this cross-sectional study. Exploratory factor analysis was used to find the factor structure for Engagement. Confirmatory factor analysis was used to test the factor structure for all three components. The proposed factor structure for frequency of participation (daily living participation frequency, mobility participation frequency, learning participation frequency and community participation frequency) and independence (daily living independence and social participation independence) fit with data from FUNDES-Child-SE after excluding three to five items and adding two to five covariances of residuals. In the engagement component, two factors, named engagement in informal activities and engagement in formal activities, were found. After excluding one item and adding 10 covariances of residuals, the factor structure had an acceptable fit to data. Differences in components' factor structure indicate that attendance and engagement are separate aspects of participation. Before using numeric scores from FUNDES-Child-SE in clinical settings, responsiveness and interpretability should be evaluated.

The Comparison of Several Factorial Structures of the Cornell Critical Thinking Test Level Z

"The Cornell Critical Thinking Test (CCTT) level Z is a broadly applied instrument for the measurement of undergraduate, gifted students’ and adults’ critical thinking abilities, however, there is a lack of studies in the literature investigating its factorial structure. The test developers emphasize the interpretation of the test results as a general critical thinking factor, including different cognitive abilities, but also highlight the overlap between the items of the subfactors. The aim of the study is the investigation of internal consistency, the comparison of different factorial structures (unidimensional, correlated, and hierarchical models), and gender invariance testing of the CCTT level Z. Hungarian-speaking undergraduate students participated in the study (N = 825). For the confirmatory factor analysis (CFA) the Mplus version 8.7, with weighted least squares mean and variance adjusted estimation was used. Measurement invariance of the test across genders was analyzed using Muthén’s two-step procedure for dichotomous data. The results indicated that the correlated four-factor and second-order structures of the test exceeded the acceptable model fit criteria. Post hoc inspection was conducted on the second-order four-factor model, indicating a shortened 22-item version of the test (with a general critical thinking factor, including four subfactors: deduction, meaning and fallacies, induction, assumption identification) with excellent fit indices [χ2 (203) = 259.309, CFI = .967, TLI = .963, RMSEA = .018, SRMR = .056]. Configural and scalar invariance of the abbreviated Hungarian version of the test across genders were confirmed. Keywords: critical thinking, undergraduate students, confirmatory factor analysis, measurement invariance"

Factor structure of the Impact of Events Scale-Revised in Latin American young adults.

More than 550 million people speak Spanish and, yet, psychometric data on psychological instruments in Spanish lags. Given evidence of significant traumatic exposure and distress among Spanish speakers, the aim of the current study was to examine the factor structure of the Impact of Events Scale-Revised (IES-R), in a large sample of Spanish-speaking adults. Participants (n = 725) were university students living in Latin America (M = 21.02; SD = 3.12). Most were born in Mexico (77.6%) and the next largest subgroup was from Ecuador (18.9%). Respondents completed the 22-item IES-R. The IES-R mean score was 20.08 (SD = 21.34) and 26.6% of the sample met the cutoff score for clinically significant symptoms. Regarding factor structure, eight different factor structures that have demonstrated a good fit in the extant literature were examined. The one-factor model demonstrated an acceptable fit, χ²(209) = 839.13, p < .0001; root-mean-square error (RMSEA) = 0.06, 95% confidence interval (CI) [0.06, 0.07]; comparative fit index (CFI) = 0.91, Tucker-Lewis index (TLI) = 0.90. The two-factor model demonstrated good fit, χ²(208) = 746.70, p < .0001; RMSEA = 0.06, 95% CI [0.05, 0.06]; CFI = 0.92, TLI = 0.91, and nested model comparisons of the two-factor and one-factor models using the chi-square difference test supported the two-factor model. The most parsimonious of the multifactor models, a two-factor model with Avoidance symptoms as one factor and Intrusions and Hyperarousal combined into a second may be of greatest use for this particular version of the IES-R. The current research demonstrates strong psychometric support for Intrusion/Hyperarousal and Avoidance subscales when measuring traumatic stress in Spanish speakers and underscores the need for culturally and contextually sensitive assessment in this population, in which posttraumatic stress is prevalent.

The Human-Animal Interaction at Work Scale: Development and psychometric properties

This study intended to develop and validate the Human-Animal Interaction at Work Scale (HAI@WS). This instrument aims to measure human-animal interactions taken during work time.We conducted four studies. First, we conducted a study to develop the scale, then we conducted another one to explore its factorial structure (N=1013). A third study served to analyze its internal validity and reliability (N=253). A fourth daily-diary study analyzed the criterion validity of the HAI@WS, by exploring its within-person correlations with measures of performance, satisfaction, and work engagement (N= 145⁎5=725).The findings revealed that the 3-item scale accounted for a single factor and is a reliable measure to assess human-animal interactions in the work context. Moreover, the results also showed that the scale was significantly related to measures of performance, satisfaction, and work engagement at the within-person level.This study develops and validates a measure that is essential for studies focused on human-animal interactions in the work context, as so far there were no measures to do it.The HAI@WS completes a gap in the research by providing a measure that may support managers to evaluate to what extent the presence of pets at work – both teleworking and at the office - and their subsequent interactions with their workers may satisfy biological and inner psychological needs, thus promoting positive outcomes such as work engagement or positive affective work-related experiences.This research gives a step forward in the knowledge about human-animal interactions and this may affect the individual and the organization.
