  • Giuseppina Martino + 10 more

Telemedicine is increasingly used in the management of inflammatory bowel disease (IBD), improving access to specialized care. Assessing patient satisfaction is crucial to optimize telemedicine services. The Telemedicine Satisfaction Questionnaire (TSQ) is widely adopted, but its cross-cultural validity requires evaluation. This study aimed to translate, culturally adapt, and validate the Italian version of the TSQ (I-TSQ) for IBD care. A prospective cross-sectional study was conducted at two IBD centers in Italy between June and October 2024. The TSQ was translated and culturally adapted following international guidelines, including forward-backward translation and pilot testing. Structural validity was assessed using exploratory and confirmatory factor analyses (EFA and CFA). Internal consistency was evaluated with Cronbach's alpha and McDonald's omega. Participants completed the I-TSQ after telemedicine consultations via an online platform. A total of 180 patients participated. Factor analyses supported a three-factor model: Quality of Care, similarity to Face-to-Face Encounters, and Perception of Interaction. CFA confirmed a good model fit (χ2<inf>(62)=</inf>212.547, P=0.183; CFI=0.926; RMSEA=0.047; SRMR=0.097). Internal consistency was good (McDonald Omega = 0.88). Most patients (80%) reported that telemedicine positively impacted their disease management, and 87% found technology access easy or very easy. The Italian version of the TSQ is a valid and reliable tool for assessing satisfaction with telemedicine in IBD care. Its use may support the integration of telemedicine into hybrid, patient-centered care models.

Proactive personality is an essential disposition determining students’ readiness to enter the workforce, so a validated instrument is needed to measure it in Indonesia. This study aimed to adapt the Proactive Personality Scale–Short Version (PPS-SV) into the Indonesian language and test its validity and reliability in a student population. A total of 232 students (61 men, 171 women) from a university in Bandung participated in the study. The age range of the participants was 19–25 years old (\textit{M} = 21.7; \textit{SD} = 1.12). Construct validity was tested using confirmatory factor analysis (CFA), while reliability was estimated using Cronbach's alpha and McDonald's omega. The CFA results confirmed the one-factor structure of the PPS-SV and demonstrated good model fit with the data (CFI = .964, TLI = .954, GFI = .994, RMSEA = .069, and SRMR = .036). The scale also showed excellent internal consistency ($\alpha$ = .901; $\omega$ = 0.902). Thus, the Indonesian adaptation of the PPS-SV was judged to have strong psychometric properties, including good construct validity and reliability. This scale can therefore be recommended for measuring proactive personality in students in Indonesia.

  • Behavioral sciences (Basel, Switzerland)
  • Moises Curo-Huacani + 5 more

Background: Writing self-efficacy is a central construct in educational research, grounded in Bandura's social cognitive theory. However, most available instruments have been developed in Western and urban contexts, which limits their applicability to indigenous bilingual populations, such as Quechua-speaking students in Peru. The absence of validated scales in these contexts hinders the accurate assessment of writing self-efficacy and the implementation of educational strategies tailored to their linguistic and cultural needs. Objective: This study aimed to adapt and validate the Writing Self-Efficacy Scale (QEWSE) for Quechua-speaking students in basic education in Peru, ensuring its structural validity and reliability. Methods: An instrumental study was conducted with a sample of 265 secondary school students (50.6% female, 49.4% male), using convenience sampling. Confirmatory factor analysis (CFA) was applied to evaluate the structure of the instrument. Reliability was assessed using Cronbach's alpha and McDonald's omega coefficients. Results: The four first-order factor model (Ideation, Skills, Usage, and Self-Regulation) showed adequate fit indices (CFI = 0.92; TLI = 0.91; RMSEA = 0.05 [90% CI: 0.05-0.06]; SRMR = 0.05). However, the high inter-factor correlations (≥0.85) suggest the relevance of a second-order model, which demonstrated a reasonable fit (CFI = 0.92; TLI = 0.91; RMSEA = 0.06; SRMR = 0.05), supporting the interpretation of writing self-efficacy as a global construct. The scale showed high reliability across all factors (α and ω ranged from 0.74 to 0.90). Conclusions: The QEWS-S demonstrates strong psychometric properties for assessing writing self-efficacy among Quechua-speaking students. The hierarchical second-order model offers a more accurate theoretical and empirical representation, allowing for the reporting of an overall self-efficacy score while also providing specific scores for each dimension. These results support its use in bilingual and culturally diverse contexts and lay the groundwork for future research aimed at further examining discriminant validity and developing pedagogical interventions focused on strengthening students' confidence and writing skills.

  • D Aslan + 1 more

Abstract 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.

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.

&lt;p&gt;&lt;strong&gt;Context and relevance.&lt;/strong&gt; The article presents the results of the application and standardization of the test "Methodology for diagnosing the general learning ability in children aged 6-7 years" (author U.V. Ulenkova, modified by N.Y. Boryakova), which allows us to identify the qualitative characteristics and disadvantages of the components of emerging learning activities. In addition, the technique serves the purposes of identifying children at "risk group" in terms of educational difficulties, as well as the purposes of differential diagnosis when distinguishing between similar conditions (mental retardation, intellectual disabilities). The methodology has been modified in terms of the criterion-evaluation apparatus. The tasks of the methodology and the assessment system have been digitized, which simplifies its use in working with children, reduces research time and facilitates the processing of the data obtained. &lt;strong&gt;Objective.&lt;/strong&gt; Check the modified version of the methodology for validity, reliability and determine statistical norms. &lt;strong&gt;Hypothesis.&lt;/strong&gt; The modified version of the methodology will correspond to the psychometric properties of a high-quality diagnostic tool, will be valid and reliable. &lt;strong&gt;Methods and materials.&lt;/strong&gt; The standardization sample consisted of 1701 children aged 6-7 years from 72 to 95 months (M = 84.79 months; SD = 5.76 months). The factor structure of the questionnaire was checked using bifacial analysis, reliability using the alpha Cronbach and omega MacDonald coefficients, differential validity using the Mann-Whitney U criterion, external validity using the Spearman correlation coefficient and using the additional "Raven Color Progressive Matrices" technique. &lt;strong&gt;Results.&lt;/strong&gt; In this format, the "Methodology for diagnosing the general learning ability in children aged 6-7" underwent a standardization procedure, as a result of which good external and differential validity was determined, high reliability was proved, norms for the development of the general learning ability of children aged 6-7 were determined, as well as qualitative characteristics of its motivational, target, operational and regulatory components. &lt;strong&gt;Conclusions. &lt;/strong&gt;The results of the study suggest that a modified version of the methodology can be used by psychologists for scientific and practical purposes to support the educational process.&lt;/p&gt;

The present study aimed to validate the Italian 8-item, 9-item, and 12-item versions of the Depression, Anxiety and Stress Scale-21 (DASS-21), addressing the need for shorter yet psychometrically robust measures. Two studies were conducted with different samples. In Study 1 (n = 541), confirmatory factor analysis (CFA) and reliability testing of the short-form versions of the DASS were performed, and their convergent validity with life satisfaction and mental well-being was examined. Study 2 (n = 321) extended this validation by reassessing factor structure, reliability, and convergent validity using constructs associated with psychological distress, including positive and negative affect, self-esteem, and perceived stress. Results demonstrated that all short-form versions retained the three-factor structure of the original DASS-21, with overall sufficient fit indices, especially the 9-item model. Reliability metrics confirmed internal consistency (all Cronbach's alpha and McDonald's omega ≥0.70). Convergent validity analyses indicated strong correlations between the short-form versions of DASS-21 (min = 0.675, max = 0.956) and associated psychological constructs, aligning with theoretical expectations. The scales captured the relationships between psychological distress, positive and negative affect, perceived stress, mental well-being, self-esteem, and life satisfaction. Findings suggest that the Italian versions of the DASS-8, DASS-9, and DASS-12 provide feasible and reliable alternatives to the DASS-21 for assessing depression, anxiety, and stress, supporting their usefulness in clinical and research contexts, particularly in circumstances in which brevity is essential.

  • Shankey Verma + 2 more

Instagram's popularity has raised concern about its problematic use. However, no validated scales assessing Instagram addiction exist in the Indian context. The present study evaluated the psychometric properties of the 15-item Instagram Addiction Scale (IAS-15) among Indian adults. In total, 301 participants (Mage = 22.89 years) were recruited using a convenience sampling technique. Confirmatory factor analysis indicated that the two components of the IAS-15, social effect and compulsion, had suitable factor loadings: CMIN/DF (chi-square/degree of freedom) = 2.531, GFI (goodness of fit index) = 0.903, IFI (incremental fit index) = 0.965, TLI (Tucker-Lewis index) = 0.958, CFI (comparative fit index) = 0.965, and RMSEA (root mean square error of approximation) = 0.071. This was further improved by drawing covariances between theoretically linked items (CMIN/DF = 2.273, GFI = 0.916, IFI = 0.972, TLI = 0.965, CFI = 0.971, and RMSEA = 0.065). Strong convergent validity with a significant and positive correlation with social media addiction (r = 0.899), and strong concurrent validity with depression (r = 0.778), anxiety (r = 0.777), stress (r = 0.815), and negative correlations with self-esteem (r = -0.635) were observed. The IAS-15 demonstrated excellent internal consistency with Cronbach's alpha (α) and McDonald's omega (ω) coefficients of reliability for the overall scale (α = 0.962 and ω = 0.963) and its two subscales, social effect (α = 0.941 and ω = 0.942) and compulsion (α = 0.922 and ω = 0.922). Findings confirm that the IAS-15 is a valid and reliable instrument for assessing Instagram addiction among Indian adults.

  • Sep 2, 2025
  • Psicologia, reflexao e critica : revista semestral do Departamento de Psicologia da UFRGS
  • Clara Paz + 3 more

The Clinical Outcomes in Routine Evaluation (CORE) system is widely used to assess psychological well-being and clinical symptoms across various settings, but most studies on its psychometric properties have focused on clinical populations and the 34-item version, leaving a gap in understanding the performance of shorter versions and its applicability in non-help-seeking samples. This study investigates the acceptability, reliability, and score distributions of various formswithin the CORE system among a non-help-seeking Spanish population. Data from 1667participants were analyzed, with a mean age of 37.16 years and a predominance of women (59.1%).The majority had higher education (53.1%), and over half were employed at the time of the study. Acceptability was high, with low item omission rates (<0.1%) across all forms during both initial and retestassessments. Internal consistency was strong, with Cronbach's alpha and McDonald's Omega exceeding 0.80 for all forms. Test-retest reliability showed correlations above 0.59 for all scores, with no significant differences betweenassessment intervals. Score distributions were compared by gender, age, and education, revealing significantdifferences between gender and education but not for age. The study provides key reference data for the CORE system in Spain, supporting outcome comparisonsin non-help-seeking samples. Despite an overrepresentation of highly educated individuals, it offers crucial insightsinto its psychometric properties and score distributions. The findings highlight potential applications of thesedistributions and underscore the need for further research into the psychometric performance of individual COREforms.

  • Aug 21, 2025
  • Psicologia, reflexao e critica : revista semestral do Departamento de Psicologia da UFRGS
  • Andrés Ramírez + 6 more

The aim of this study was to evaluate the psychometric properties of the Dating Violence Questionnaire for Victimization and Perpetration (DVQ-VP) in a sample of the Ecuadorian population. The study included 819 participants (47% men and 53% women), consisting of Ecuadorian adolescents and university students. An instrumental design was employed for the linguistic adaptation, reliability, and convergent (AVE), discriminant (HTMT), and structural (CFI, TLI, and RMSEA) validation of the DVQ-VP. The construct validity and internal consistency of the instrument were assessed. Construct validity was analyzed using confirmatory factor analysis (CFA), while internal consistency was evaluated using ordinal Cronbach's alpha and McDonald's omega coefficients. Additionally, a network analysis was conducted with the DVQ-VP items. The CFA results indicated that the DVQ-VP has a factorial structure consistent with the original theoretical model, with adequate fit indices (CFI > 990, TLI > 990, and RMSEA < 0.08 in both models of the DVQ-VP). The Cronbach's alpha and McDonald's omega values for the victimization and perpetration subscales were above .70, indicating good internal consistency. Additionally, the instrument proved to be sensitive in identifying different forms of dating violence. The findings support that the DVQ-VP demonstrated adequate levels of validity and reliability for assessing dating violence in a sample of Ecuadorian adolescents and university students. These results suggest that, within this specific context and population, the instrument can be a useful tool for identifying patterns of victimization and perpetration in dating relationships. Its application may contribute to early detection and the development of targeted interventions to reduce intimate partner violence among young people.

  • BMC psychiatry
  • Sanrong Xiao + 5 more

Die by suicide is a significant public health issue globally, especially among individuals with mental health diagnoses. An efficient and reliable tool for suicidal intervention is urgently needed to identify those who are in danger. A widely recognized tool for assessing the risk of death by suicide around the world is the Columbia-Suicide Severity Rating Scale (C-SSRS). This study conducted an assessment of the C-SSRS's psychometric qualities among participants with mental health diagnoses in China. Of the 614 individuals diagnosed with mental health diagnoses who participated in the study, 161 had previously attempted to take their own life. Reliability was assessed using Cronbach's alpha and McDonald's omega. The construct validity was tested using ULSMV (unweighted least squares with mean- and variance-adjusted standard errors). Discriminant and convergent validity were evaluated using the third item of the Hamilton Depression Rating Scale (HAMD-17) and the Schizophrenia Quality of Life Scale (SQLS). Participants' history of suicide attempts was used to calculate predictive validity. The analysis demonstrated that the C-SSRS exhibited satisfactory internal consistency. The Cronbach alpha was 0.869, and McDonald's omega was 0.871. The C-SSRS's three-factor structure and the two-component structure of the suicidal ideation intensity subscale were both validated by confirmatory factor analysis (CFA). Data analysis revealed that the active-passive model has a relatively better overall scale fit (χ²/df = 3.862, RMSEA = 0.068, SRMR = 0.0605, CFI = 0.917, IFI = 0.918, AGFI = 0.884). A high composite reliability value supports convergent validity. Both discriminant and divergent validity are satisfactory. Predictive validity indicates that the four subscales of the C-SSRS can effectively predict suicide attempts. This study is the first to examine the scale factor model and the active-passive model of the C-SSRS among individuals with mental health diagnoses in China. The results demonstrated that the C-SSRS has sufficient validity and reliability, making it suitable for assessing suicidal attempts and thoughts in individuals with mental health diagnoses and for distinguishing between active and passive suicidal ideation. These findings require confirmation in other populations through future research.

The dental anxiety scale (DAS) - psychometric properties and longitudinal findings among middle-aged adults.
  • Aug 21, 2025
  • BMC psychology
  • David Bantel + 6 more

The Dental Anxiety Scale (DAS) is a well-established instrument for assessing dental anxiety. While numerous cross-sectional studies have examined the DAS, longitudinal research investigating age-related changes, reliability, validity over time, associations with mental and physical health, and demographic determinants remains limited. Furthermore, the possibility of longitudinal changes in its factor structure has received limited attention. In 2013/2014, N = 329 German adults (53.6% female, mean age 40.20 years) and in 2019/2020, N = 323 adults (55.7% female, mean age 47.15 years) completed questionnaires, including the DAS, Oslo Social Support Scale (OSSS-3), Health-Score (G-Score), Patient Health Questionnaire (PHQ-2), Generalized Anxiety Disorder Screener (GAD-2), Short Scale for General Life Satisfaction (L-1), and oral health behavior items. DAS reliability was assessed using Cronbach's alpha and McDonald's omega, and factor structure via principal component analyses (PCA). Longitudinal dynamics were analyzed using McNemar's test. Associations between dental anxiety and independent variables were investigated using correlational analyses and Wilcoxon signed-rank tests. DAS significantly declined from 2013/2014 (M = 9.47) to 2019/2020 (M = 9.21). Internal consistency was excellent (α/Ω = 0.93), and a correlation of dental anxiety across waves was high (rs = 0.79). PCA revealed a stable one-factor structure (2013/2014: 82.25%, 2019/2020: 82.86% explained variance). McNemar test indicated no significant changes in the proportion of subjects with or without dental anxiety over time. Higher dental anxiety was significantly correlated with lower levels of: life satisfaction, perceived influence over health, condition of health, physical and mental health, and social support in both waves (all rs ≥ 0.14; p ≤ 0.015). A significant decrease in dental anxiety over time was observed in participants with frequent tooth brushing, no indication for depression, and at least moderate social support (all z ≤ -2.07, all p ≤ 0.019). This study provides evidence for DAS's reliability, temporal stability, and construct validity. Although dental anxiety showed a statistically significant decline it remains relatively stable for most participants. Findings indicate meaningful associations with psychosocial, behavioral, and health-related factors, supporting the potential value of interdisciplinary approaches that include psychological support in oral health care.
