Psychometric properties of the Dating Violence Questionnaire for Victimization and Perpetration (DVQ-VP) in Ecuadorian population.

This study aimed to translate, cross-culturally adapt, and validate the CDPQOL questionnaire, a coeliac disease (CD)-specific paediatric health-related quality of life (HRQoL) instrument (CDPQOL), in Spanish children with CD. The CDPQOL questionnaire has two versions for children aged 8-12 and 13-18. Translation and linguistic validation were performed following an international consensus process. Internal consistency was calculated using Cronbach's alpha and McDonald's omega coefficients, and convergent validity was assessed with average variance extracted (AVE). Confirmatory factor analysis (CFA) and exploratory factor analysis (EFA), when necessary, were carried out to assess the construct validity. A total of 235 children were included. In the 8-12 age group, a change in the distribution of items to a new structure of three dimensions (negative emotions, food feelings and social interaction) was required. In this new model, CFA supported the fit of the model (χ2/gl = 1.79, RMSEA = 0.077 (IC 95% 0.05-0.100), CFI = 0.969, TLI 0.960, SRMR = 0.081) and Cronbach's alpha and McDonald's omega coefficients were > 0.7 in all three dimensions. In the 13-18 age group, CFA showed that all fit indexes were acceptable (χ2/gl = 1.702, RMSEA = 0.102 (IC 95% 0.077-0.127), p < 0.001, CFI = 0.956, TLI = 0.947, SRMR = 0.103) and Cronbach's alpha and McDonald's omega coefficients were > 0.7 in all three dimensions, except for uncertainty dimension. Conclusions: The Spanish version of the CDPQOL questionnaire is a useful instrument to assess quality of life in coeliac children whose native language was Spanish spoken in Spain, with changes in item distribution in the younger age group questionnaire. What is Known: • The first specific questionnaire for coeliac children, Dutch Coeliac Disease Questionnaire (CDDUX), which focuses on diet, was translated into Spanish and validated allowing to evaluate the HRQoL of Spanish coeliac children. • Spanish Children and parents feel the disease had no substantial negative impacts on patient HRQoL using this questionnaire, similar to that observed with other countries. What is New: • The age specific for CD children (CDPQOL) was elaborated in the USA and focuses on other aspects not evaluated by CDDUX such as emotional and social issues related to living with CD. • The CDPQOL was translated into Spanish and validated allowing it to be used to assess Spanish coeliac children's QoL.

Background:Due to the growing prevalence of suicide, assessing people's attitudes toward suicide is necessary. Therefore, this study aimed to examine the psychometric properties of the Persian version of the Predicaments Questionnaire (PQ), measuring social attitudes toward suicide.MethodsThis psychometrics study evaluated face validity, content validity, temporal stability, internal consistency, and construct validity. First, the questionnaire was translated into Persian by the translate-back-translate method. The Persian version was provided to 10 experts in psychiatry for further revision. Two indicators, CVR and CVI, were calculated to evaluate the content validity. To check the face validity, we prepared a form and gave it to 10 people outside the campus to submit their opinions. Temporal stability was investigated by the test-retest method, reporting Intraclass correlation (ICC). Internal consistency was assessed by reporting Cronbach's alpha and McDonald's Omega coefficients. Construct validity was assessed using the confirmatory factor analysis to determine the number of dimensions of the questionnaire.ResultsA total of 151 students were enrolled with a mean age of 25 (SD = 0.32). The Persian PQ was valid in terms of content validity and face validity. Furthermore, it was reliable as Cronbach's alpha, McDonald's Omega, and the ICC were 0.94, 0.943, and 0.998, respectively. In addition, the confirmatory factor analysis yielded one dimension. Finally, after reviewing the experts' comments, the final amendments were made, and only question 29 was removed from the final version.ConclusionConsequently, the Persian version of the PQ is acceptable in terms of content validity, face validity, temporal stability, and internal consistency.

BackgroundEducational leadership plays a crucial role in the development of nursing students, significantly enhancing their clinical skills and preparing them to lead advancements in healthcare. This comprehensive educational approach ensures that nursing students are well-equipped to address contemporary healthcare challenges effectively.AimThis study aimed to translate the Educational Leadership Scale for Nursing Students into Persian and evaluate its psychometric properties among Iranian nursing students.MethodsThis cross-sectional methodological study was conducted in two phases: translation and cultural adaptation, followed by psychometric evaluation. After obtaining permission from the original scale developer, the scale was translated into Persian using the Pilot and Yang model. Face and content validity were assessed both qualitatively and quantitatively. Construct validity was evaluated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). A convenience sample of 469 nursing students from nursing faculties in Kermanshah Province, Iran, completed the questionnaire. Internal consistency was evaluated using Cronbach's alpha and McDonald's omega coefficients. Test–retest reliability was assessed using the intraclass correlation coefficient (ICC) in a subsample of 47 nursing students.ResultsExploratory and confirmatory factor analyses confirmed the three-factor structure of the Persian version of the instrument, with 19 items accounting for 63.80% of the total variance. The model fit was excellent, as shown by the CFI, GFI, TLI, RMSEA, and SRMR values. The scale demonstrated acceptable internal consistency reliability, with Cronbach's alpha at 0.924 and McDonald's omega at 0.923. The ICC for the total score was 0.924 (95% CI: 0.910–0.936).ConclusionThe results of the present study indicate that the Persian version of the Educational Leadership Scale for Nursing Students possesses acceptable psychometric properties. The results of face, content, and construct validity, along with reliability indices (including internal consistency and test–retest reliability), indicate that this instrument is an effective tool for evaluating educational leadership characteristics among Iranian nursing students. However, to further confirm the validity and reliability of this scale, future studies with larger and more diverse samples of nursing students, including those in clinical settings, are recommended. Furthermore, examining the criterion validity and discriminant validity of this instrument could contribute to a better understanding of its psychometric characteristics.

The rise of gaming as a dominant form of entertainment has raised global concerns over problematic use, prompting the need for culturally adapted assessment tools. This study investigates the psychometric properties of the Gaming Disorder Test (GDT) and the Gaming Disorder Scale for Young Adults (GADIS-YA) among Indian university students. A total of 454 participants completed the GDT, GADIS-YA, Internet Gaming Disorder Scale-Short Form (IGDS9-SF), and Depression Anxiety Stress Scale-21 (DASS-21). We assessed internal consistency using Cronbach's alpha, McDonald's omega, and construct validity through confirmatory factor analysis (CFA). The GDT and GADIS-YA demonstrated good internal consistency with Cronbach's alpha and McDonald's omega coefficients at 0.88 and 0.93, respectively. CFA supported a one-factor structure for GDT and a two-factor structure for GADIS-YA. Measurement invariance was confirmed across gender and gaming time, with significant correlations observed with IGDS9-SF and DASS-21. These findings indicate that GDT and GADIS-YA have satisfactory psychometric properties among young Indian adults. The findings contribute to the growing body of evidence on gaming disorder (GD) prevalence and a reliable instrument for assessing it in India. Healthcare professionals can utilize the GDT and GADIS-YA to assess GD for preventing and reducing of gaming problem among young adults.

The High Five Inventory (HFI) was developed to assess five positive personality traits: erudition, peace, joviality, honesty, and tenacity. Research on positive personality dimensions remains limited, emphasizing the importance of validating assessment tools in different cultural contexts. This study aimed to analyze the psychometric properties of the High Five Inventory (HFI) in a sample of Ecuadorian university students. An instrumental study was conducted to evaluate the construct validity and reliability of the HFI. A confirmatory factor analysis (CFA) was performed to assess the inventory's factorial structure. The sample consisted of 1,007 students (403 women, 39.9%) from various faculties at Salesiana Polytechnic University in Ecuador. Prior to data collection, a linguistic review was carried out by a panel of experts, including faculty members, researchers, and students, to ensure clarity and comprehension of the items. The final version of the inventory was administered after obtaining informed consent. The CFA results indicated an adequate model fit: χ2 (220) = 859.969, p < 0.001, robust CFI = 0.989, RMSEA = 0.054 (90% CI: 0.050-0.058), and SRMR = 0.045. Additionally, internal consistency was confirmed with Cronbach's Alpha (α) and McDonald's Omega (ω) coefficients ≥ 0.80, demonstrating strong reliability. The findings confirm that the High Five Inventory-Ecuador (HFI-E) exhibits robust psychometric properties, supporting its use in assessing positive personality traits within the Ecuadorian population. The study highlights the relevance of validating personality assessments across different cultural contexts and underscores the potential applications of the HFI-E in psychological and educational settings.

This study aimed to assess the psychometric properties of the Farsi version of the Electroconvulsive Therapy-Related Anxiety Questionnaire (ERAQ). This methodological study was conducted among patients undergoing or with a history of Electro Convulsive Therapy (ECT) in Mashhad, Iran, during 2024-2025. Data were collected using a demographic profile form and the ERAQ. The questionnaire was translated into Farsi using the forward-backward translation method, and its face and content validity were assessed both qualitatively and quantitatively. To evaluate construct validity, exploratory factor analysis (n = 150) and confirmatory factor analysis (n = 150) were performed. Convergent validity was examined using Composite Reliability and Average Variance Extracted values, while discriminant validity was assessed through the Heterotrait-Monotrait ratio. Reliability was determined by estimating internal consistency through Cronbach's alpha and McDonald's omega coefficients. During exploratory factor analysis, item 9 was removed because its factor loading was less than 0.30, and the remaining 16 items were distributed across three factors: life disruption, socio-physical disruption, and memory disruption, which collectively explained 45% of the total variance. Confirmatory factor analysis demonstrated a good fit for the proposed model. All composite reliability, maximum reliability, and heterotrait-monotrait ratios supported the convergent and discriminant validity of the ERAQ. Additionally, Cronbach's alpha and McDonald's omega coefficients confirmed the acceptable internal consistency of the Farsi version of the ERAQ. Based on the findings of this study, the Farsi version of the ERAQ demonstrates sufficient validity and reliability to assess anxiety symptoms associated with ECT in the Iranian population.

The questionnaire consists of 12 questions: seven relating to the severity of symptoms, two regarding the impact of the disease on lifestyle and work, two concerning the impact on the need for healthcare, and one is a general question. Each question is rated on a scale from 0 to 5.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Aim:&lt;/b&gt; To present the validation process and the final version of the Polish version of the COMQ-12 questionnaire.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Material and methods:&lt;/b&gt; The Polish version of the COMQ-12 questionnaire was prepared based on an independent translation of the English version by three physicians (two otolaryngology specialists and one physician in the process of specialization in otolaryngology). The questionnaire was validated in a study including 60 participants: 30 patients with chronic otitis media and 30 volunteers without a history of middle ear diseases or hearing disorders. Each participant was asked to complete the COMQ-12 questionnaire twice at an interval of 4 weeks apart. The internal consistency, reliability, and construct validity of the questionnaire were analyzed using Cronbach's alpha and McDonald's omega coefficients, Spearman's rho correlation coefficient, and the Mann-Whitney test, respectively.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Results:&lt;/b&gt; High internal consistency, reliability, and construct validity of the Polish version of the COMQ-12 questionnaire were shown in the course of statistical analysis. The overall internal consistency was 0.95 and 0.97 as assessed by Cronbach's alpha and McDonald's omega coefficients, respectively. Spearman's rho correlation coefficient was above 0.89 for each question. Statistically significant differences in the COMQ-12 total scores were obtained between patients with chronic otitis media and the control group.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Conclusions:&lt;/b&gt; The Polish version of the COMQ-12 questionnaire can be a valuable clinical tool for the assessment of the quality of life in patients suffering from chronic otitis media.&lt;/br&gt.

BackgroundMastectomy as a surgical treatment in women with breast cancer causes a change in their body image due to the loss of femininity and body integrity, decreased sense of sexual attractiveness, and dissatisfaction with the presence of surgical scars. The present study was conducted to evaluate the psychometric properties of the Farsi version of the body image scale for breast cancer survivors.MethodsThis cross-sectional study was conducted on 204 women with a mastectomy referred to Kermanshah's surgery and oncology office in 2021. Face and content validity were evaluated qualitatively. Construct validity was evaluated by exploratory factor analysis (with maximum likelihood and Promax rotation) and confirmatory factor analysis. Cronbach’s alpha and McDonald’s omega coefficients were used to verify internal consistency.ResultsThe mean age of the participants was 46.57 (SD = 9.47). One factor was extracted that explained 46.56% of the total variance of body image. The factor load of the items varied between 0.561 and 0.801. The results of CFA also showed that the final model has a perfect fit: CMIN = 20.931; DF = 13; CMIN/FD = 1.610; p = 0.074; GFI = 0.972; AGFI = 0.939; IFI = 0.985; CFI = 0.985; TLI = 0.975; PNFI = 0.595; PCFI = 0.610; RMSEA = 0.055. internal consistency based on Cronbach's alpha and McDonald's omega coefficients was 0.856 and 0.861, respectively.ConclusionThe Farsi version of the body image scale for breast cancer survivors has good construct validity and may be used in various studies in clinical and research settings.

The current study tested the one-dimensionality of the Center for Epidemiological Studies Depression Scale for Suicidal Ideation (CES-D-SI) and its reliability among high school students in Santa Marta, Colombia. A total of 1,462 tenth and eleventh-grade students from public and private schools completed the CES-D-SI. The students were between 13 and 17 years (M = 16.0, SD = 0.8), 60.3% were female, and 55.3% were in the tenth grade. A confirmatory factor analysis (CFA) was conducted, and the chi-square, root mean square error of approximation (RMSEA), comparative fit index (CFI), Tucker-Lewis index (TLI), and standardized root mean square residual (SRMR) statistics were calculated. The internal consistency of the dimension was calculated using Cronbach's alpha and McDonald's omega coefficients. The results of the CFA were as follows: chi-square = 26.51, df =2, p = .001; RMSEA = .092; 90% confidence interval = .063-.124; CFI = .983; TLI = .950; and SRMR = .019. Cronbach's alpha coefficient was .75, and McDonald's omega coefficient was .77. As conclusions, the scale exhibited a unidimensional structure similar to that in other studies and presented good reliability values. Hence, its use is recommended to screen suicidal ideation in school-aged adolescents in Santa Marta, Colombia.

To design and validate a Brazilian version of the Animal Empathy Scale, based on the existing Portuguese version. Content validity assessment was performed by expert judges, and the adapted scale was administered to a sample of 386 participants. Exploratory and confirmatory factor analyses were performed. The bifactorial profile of the scale remained consistent, comprising Empathic Concern for Animals (Cronbach's alpha and McDonald's omega coefficients: 0.75) and Emotional Attachment with Animals (Cronbach's alpha and McDonald's omega coefficients: 0.79). Considering the One Health framework, collaborative, multidisciplinary, and intersectoral approaches are essential for achieving optimal health conditions for people, animals, and the environment given their intricate interconnections. Empathy plays a crucial role in promoting proximity between humans and animals, fostering positive connections that encourage biodiversity conservation. The 13 statements were retained, confirming the validity of the animal empathy scale for use in Brazil, and a Brazilian version of the Animal Empathy Scale was established.

Loneliness has a significant impact on mental and physical health across different stages of development, with particularly evident effects during adolescence. During this period, young individuals undergo substantial social and emotional transformations, making loneliness a global concern. This study aimed to analyze the psychometric properties of the UCLA-R Loneliness Scale in Ecuadorian adolescents through exploratory and confirmatory factor analysis, assess its internal consistency, and examine factorial invariance across genders. The sample consisted of 718 school-aged adolescents (288 males and 430 females) aged 14-17 years (M = 15.72, SD = 0.747), selected through probabilistic sampling. A sociodemographic ad hoc questionnaire and the Spanish version of the 20-item UCLA-R Loneliness Scale were administered. The sample was randomly divided into two equivalent subsamples (n = 359) to separately perform an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA). The EFA was conducted using principal axis factoring, oblique rotation, and polychoric correlations. The CFA evaluated one-factor, two-factor, and three-factor models, employing fit indices such as CFI, TLI, RMSEA, and SRMR. Internal consistency was estimated using Cronbach's alpha and McDonald's omega coefficients. Additionally, factorial invariance analyses by gender were performed, along with a univariate ANOVA to examine potential gender differences. The exploratory factor analysis (EFA) results indicated the presence of two factors, whose structure explains 40.8% of the total variance, with 19 items. The confirmatory factor analysis (CFA) confirmed that the bifactor model with 19 items exhibited a superior fit compared to the unidimensional and three-factor models with 20 items, with fit indices falling within acceptable to excellent ranges (CFI = .936, TLI = .927, RMSEA = .050, SRMR = .048). Additionally, the bifactor model demonstrated measurement invariance across genders. Regarding internal consistency, the scale demonstrated a Cronbach's alpha of.876 and an omega coefficient of.83, confirming its reliability. It is concluded that the 19-item UCLA-R Loneliness Scale is a valid and reliable instrument for assessing perceived loneliness in Ecuadorian adolescents, regardless of gender. Future research could replicate these findings in other regions and cultural contexts to validate its use on a larger scale.

it is widely accepted that living in the digital transformation era, the need to develop and update new professional skills and tools in health sectors is crucially important. Therefore, this study aimed to explore the reliability and validity of the Digital Competence Indicators tool in assessing the digital skills of Greek health professionals. in this cross-sectional study, 494 health professionals, including doctors (175) and registered nurses (319) working in four Greek hospitals were recruited and willingly participated using a convenience-sampling method. The original framework of Digital Competence Indicators was translated from English to Greek based on guidelines for cross-cultural adaptation of questionnaires. The validity of the tool was explored using confirmatory factor analysis (CFA) to verify the fit of the model using inductive techniques. The instrument reliability was confirmed using Cronbach's alpha (α) and McDonald's Omega coefficients. the reliability was estimated at 0.826 (Cronbach's-α) and 0.850 (McDonald's Omega-ω). The indicators of CFA were all calculated within an ideal range of acceptance. Specifically, the CFA comparative fit index produced the following adjustment indices: x2/df = 1.152 (p = 0.037), CFI = 0.997, Lewis index (TLI) = 0.966, and root mean square error of approximation (RMSEA) = 0.018. The present study demonstrated that the Digital Competence Indicator instrument has high reliability, internal consistency, and construct validity and, therefore, it is suitable for measuring digital skills of health professionals.

Background Validated instruments are limited in the literature to assess the infodemic management capacity of the healthcare professionals. This methodological study aimed to develop and validate a scale for measuring the infodemic management capacity of the healthcare professionals. Methods The study was conducted between September 2024 and April 2025 with a total of 495 healthcare professionals working at a university hospital in Ankara, Türkiye. The participants were divided into two groups for Exploratory Factor Analysis (EFA) (n = 250) and Confirmatory Factor Analysis (CFA) (n = 245). Expert opinions were obtained to evaluate the content validity of the scale. Construct validity was assessed through EFA and CFA. Reliability was examined using Cronbach's alpha and McDonald's omega coefficients. The discriminatory power of the items was examined via corrected item-total correlations. Comparisons between the upper and lower 27% groups were conducted. The study was approved by the university's research ethics committee. Results Of the participants, 71.7% were female. Physicians comprised 65% of the sample, followed by nurses (23%) and other healthcare professionals (12%). EFA revealed a four-factor structure with 20 items, explaining 54% of the total variance. The factors were labeled as follows: Listening to the Community (3 items), Supporting Communication (5 items), Building Resilience (6 items), and Engaging and Empowering Communities (6 items). Both first- and second-order CFA supported this structure, indicating acceptable model fit. Cronbach's alpha and McDonald's omega coefficients for each factor exceeded .70 (range: .71-.92). All items demonstrated adequate discriminatory power, with corrected item-total correlations above .30. Additional analysis confirmed measurement invariance across genders. Conclusions The scale is an instrument that produces valid and reliable measures and that can be used to determine health professionals’ infodemic management capacity. Key messages • Assessing the infodemic management capacity of the health professionals is a need. • The scale provides valid and reliable measures, making it a valuable tool for assessing health professionals’ infodemic management capacity.

Introduction: Suicidal ideation is an understudied issue during the gestational period, requiring valid and reliable instruments for timely measurement and to provide support in perinatal mental health. However, there are limited scales available to assess suicidal ideation in pregnant women in Colombia.Objective: To explore the dimensionality and internal consistency of the Roberts’ scale for suicidal ideation in pregnant women from Santa Marta, Colombia.Methods: 172 pregnant women between 18 and 44 years of age (M=24.7; SD=5.49) completed the Roberts suicidal ideation scale. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out to determine dimensionality and Cronbach's alpha and McDonald's omega coefficients were calculated to establish internal consistency.Results: In the CFA the Roberts’ scale indicated a unidimensional internal structure explaining 50.5% of the variance and with adequate goodness-of-fit indicators (X2=5.85, gl=2, p&lt;0.054; RMSEA=0.104 (CI90%=0.000-0.210); SRMR=0.025; CFI=0.981; TLI=0.944). Cronbach's alpha coefficient was 0.781 and McDonald's omega coefficient was 0.801, showing acceptable internal consistency.Conclusions: Roberts’ scale is a brief, reliable measure with strong validity evidence for assessing suicidal ideation in pregnant women. Further instrumental studies with a larger sample size are recommended to corroborate the psychometric performance of the instrument in the Colombian population.
