Confirmatory Factor Analysis and Internal Consistency of the Suicidal Ideation Scale of the Center for Epidemiological Studies Depression Among Colombian Adolescents.

Why physically active people report lower anxiety than those who are inactive is not well understood. This study examined whether physical self-concept and self-esteem would mediate associations of self-reported physical activity with anxiety disorder symptoms in young women, a population with elevated risk for developing an anxiety disorder. College women (N = 1036, mean ± SD = 19.7 ± 2.9 yr) completed a physical activity recall, the Psychiatric Diagnostic Screening Questionnaire, and the Physical Self-Description Questionnaire. Structural equation modeling was used to test hypotheses. Physical activity had inverse, indirect associations with symptoms of social phobia, generalized anxiety disorder, and obsessive-compulsive disorder that were expressed through its positive association with specific and global physical self-concept and self-esteem. The results were independent of similar relations with symptoms of major depressive disorder as well as the estimates of body fatness and use of psychotropic medications. These correlational findings provide initial evidence to warrant experimental efficacy trials of whether physical activity will reduce the risk of anxiety disorders in young women by positive influences on physical self-concept and self-esteem.

BackgroundThe Normalization MeAsure Development (NoMAD) questionnaire is used to assess implementation processes based on Normalization Process Theory (NPT). However, its psychometric properties have not been extensively evaluated. This study aimed to examine the factorial validity, internal consistency, and measurement invariance at both scale and item levels of the NoMAD across three hybrid effectiveness-implementation studies determining the impact of routine symptom surveillance and guideline-based symptom management interventions in ambulatory oncology care settings.MethodsA cross-sectional survey was conducted with 328 healthcare personnel (74.% clinicians) participating in the Improving the Management of SymPtoms during And following Cancer Treatment (IMPACT) Research Consortium between 2019 and 2024. Confirmatory factor analysis (CFA) tested the hypothesized four-factor structure (coherence, cognitive participation, collective action, reflexive monitoring). Internal consistency was assessed with McDonald's omega and Cronbach's alpha coefficients (> 0.70 acceptable). Measurement invariance was tested across research centers, professional roles, and years in current roles using multi-group CFA. Model fit was defined by standard fit indices (Comparative Fit Index (CFI) and Tucker-Lewis Index (TLI) values ≥ 0.95, Root Mean Square Error of Approximation (RMSEA) values ≤ 0.06, and Standardized Root Mean Square Residual (SRMR) values ≤ 0.08. Differential item functioning (DIF) was evaluated using ordinal logistic regression and item response theory methods (ΔR2 ≥ 0.02 indicative of meaningful DIF).ResultsThe four-factor model demonstrated good fit to the data (CFI = 0.97, TLI = 0.96, RMSEA = 0.06, SRMR = 0.05). All factor loadings were statistically significant (p < 0.001), ranging from 0.606 to 0.871. Internal consistency was satisfactory for all four constructs (Omega range: 0.789–0.864, Cronbach's alpha range: 0.782–0.863). The NoMAD exhibited configural, metric, and scalar invariance across research centers, roles, and years in the current role. One item ("The staff agree that the intervention is worthwhile") showed uniform DIF across healthcare systems (ΔR2 = 0.047), but no DIF was found by role or years in the current role.ConclusionsThis study supports the factorial validity, internal consistency, and measurement invariance of the NoMAD across three oncology implementation efforts. The presence of DIF in one item provides an opportunity for refinement in this healthcare context. Researchers and practitioners can use the NoMAD to assess and compare implementation processes, informing the development and evaluation of implementation strategies.Trial registration(ClinicalTrials.gov ID NCT03850912, NCT03892967, NCT03988543).

The Double-Edged Sword Effects of Career Calling on Occupational Embeddedness: Mediating Roles of Work–Family Conflict and Career Adaptability

This study aimed to develop and validate an instrument to assess dentists' adherence to infection control protocols and explore psychological factors related to infectious diseases in dental practice. The instrument was developed through phases including context validity, face and semantic analysis, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Internal consistency was evaluated using McDonald's Omega coefficient (ω) and Cronbach's Alpha (α). A total of 405 individuals completed the instrument. EFA (n = 135) revealed a four-factor structure (Work Environmental Protection, Disinfection, Team Training, and Fear and Anxiety) with 23 items with factor loadings above 0.60. The Kaiser-Meyer-Olkin (KMO) value was 0.803, and Bartlett's test of sphericity was significant (χ2: 2501.136, df:253.000, p < 0.001). CFA (n = 270) confirmed an acceptable model fit: χ2/df: 1.75; Comparative Fit Index (CFI): 0.997; Tucker-Lewis Index (TLI): 0.996; Standardized Root Mean Square Residual (SRMR): 0.079; Root Mean Square Error of Approximation (RMSEA): 0.053, supporting the four-factor structure from the EFA. Reliability analysis demonstrated strong internal consistency across all factors (ω and α ≥ 0.70). The developed instrument exhibited appropriate validity, reliability, and internal consistency, providing a suitable tool to evaluate infection control adherence and psychological aspects among dentists facing infectious diseases.

The Patient Health Questionnaire-8 (PHQ-8) is a measure of depression symptom severity that is the 8-item version of the more widely used Patient Health Questionnaire-9 (PHQ-9). However, the PHQ-8 lacks the question about suicide ideation and is often used when questions about suicide ideation cannot be administered. A recent review of the literature on the PHQ-9 indicates mixed findings on factor structure, with evidence for both a unidimensional model and a 2-factor model of somatic and non-somatic symptoms. To date, few studies have explored the factor structure of the PHQ-8, and none to our knowledge have examined this in military samples. This secondary analysis examined this in a sample of military sexual assault survivors given their heightened risk for depression. Service members and veterans who experienced assault (N = 346; 49.1% female) completed the PHQ-8 in a previously published study. The parent study was approved by the Utah State University Institutional Review Board (IRB) and secondary analyses were exempted from IRB review by the Arizona State University IRB. Five structural models were tested using confirmatory factor analysis, including 1 unidimensional factor model and 4 2-dimensional factor models. The following goodness of fit statistics were compared between models: Chi-squared testing, Comparative Fit Index (CFI), Tucker Lewis Index (TLI), root mean square error of approximation (RMSEA), Bayesian Information Criterion (BIC) and standardized root mean square residual (SRMR). Strong model fit was determined by a CFI and TLI ≥ .95, RMSEA ≤ .06, and SRMR ≤ .08. The 2-dimensional model with anhedonia, depressed mood, feelings of worthlessness, concentration difficulties, and psychomotor agitation/retardation specified on the non-somatic factor, and sleep difficulties, fatigue, and appetite changes specified on the somatic factor had the most optimal fit (X2 [df] = 46.19 [19], CFI = 0.98, TLI = 0.97, RMSEA = 0.06, SRMR = 0.03, BIC = 6,130.98). Other models had adequate fit, though the fit for the unidimensional model was statistically inferior. The use of 2-factor models of depression might be superior compared to the unidimensional model in samples of military sexual assault survivors which may provide clinical utility in treating specific depression symptom clusters. Studies that wish to examine potential differences in outcomes as a function of somatic and non-somatic depressive symptoms may consider this model. Future studies should examine model fit in samples that may not have been exposed to military sexual assault.

BackgroundThe Maslach Burnout Inventory (MBI) is an instrument commonly used to evaluate burnout syndrome. The goal of the present study was to assess the internal reliability and the performance of the items and the subscales of the MBI-HSS (the version for professionals working in human services) by validating its factorial structure in Spanish urgency healthcare personnel.MethodsCross-sectional study including 259 healthcare emergency professionals (physicians and nurses) in the Spanish health region of Lleida and the Pyrenees. Burnout was measured using the Spanish validated version of the MBI-HSS. Internal reliability was estimated using Cronbach’s alpha coefficient. The sampling adequacy was assessed using the Kaiser-Meyer-Olkin measure along with the Bartlett’s test of sphericity. A principal axis exploratory factor analysis with an oblique transformation of the solution and a confirmatory factor analysis with maximum likelihood estimation were performed. Goodness-of-fit was assessed by means of the chi-square ratio by the degrees of freedom, the standardized root mean square residual (SRMR), the root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI).ResultsThe three subscales showed good internal reliability with Cronbach’s alpha coefficients exceeding the critical value of 0.7. Exploratory factor analysis revealed five factors with eigenvalues greater than 1. Nevertheless, confirmatory factor analysis showed a relatively satisfactory fit of the three-factor structure (χ2/df = 2.6, SRMR = 0.07, RMSEA = 0.08, TLI = 0.87, CFI = 0.89), which was improved when several items were removed (χ2/df = 1.7, SRMR = 0.04, RMSEA = 0.05, TLI = 0.97, CFI = 0.98).ConclusionsAlthough it is necessary exploring new samples to get to more consistent conclusions, the MBI-HSS is a reliable and factorially valid instrument to evaluate burnout syndrome in health professionals from the Spanish emergency services.

ABSTRACTOBJECTIVE:To assess the Functional Index Questionnaire (FIQ) structure using confirmatory factor analysis (CFA) in Brazilian patients with anterior knee pain.METHODS:Brazilian patients of both sexes (n = 100), aged ≥ 18 years, with anterior knee pain for at least 3 months were included. Eligible participants completed an online form that collected personal and clinical data as well as responses to the assessment tools. We used CFA and the following fit indices: chi-square/degrees of freedom (DF), comparative fit index (CFI), Tucker–Lewis index (TLI), root mean square error of approximation (RMSEA), and standardized root mean square residuals (SRMR).RESULTS:The majority of the respondents were women, young adults, overweight, with incomplete higher education, were physically active, and had pain in sitting or squatting positions. The mean duration of pain was 38.24 months, and the mean pain intensity was 4.54 points. The model fit indices were as follows: χ2/DF = 2.08, TLI = 0.978, CFI = 0.969, RMSEA = 0.104, and SRMR = 0.077. Therefore, the one-dimensional structure with eight items yielded an RMSEA value above the 0.08 cutoff point, suggesting a poorer fit and more residual error than is acceptable for a well-fitting model. Using the modification indices within the CFA, we observed a correlation between Items 2 (climbing up two flights of stairs [16 steps]) and 6 (climbing up four flights of stairs [32 steps]) and Items 3 (squatting) and 4 (kneeling), indicating the similarity in the response pattern for these items. After adding these correlations to the model, we obtained improved fit indices (χ2/DF = 1.51, TLI = 0.990, CFI = 0.985, RMSEA = 0.072, and SRMR = 0.061).CONCLUSION:This version of the FIQ should be used with caution, as the unidimensional model demonstrates substantial residuals, mainly because of item redundancy.

BackgroundThe patient’s perception of nurses’ caring behaviors predicts the quality of care they receive. Existing measurement tools have either not undergone psychometric evaluation or contain too many items, leading to participant fatigue. This study tested the psychometric properties of the 14-item Persian version of the nurse caring behavior scale (P-NCBS).MethodsThis cross-sectional study involved 327 hospitalized patients in Bam, Iran. The Nurse Caring Behavior Scale (NCBS) was translated into Persian using a forward-backward translation method. Psychometric evaluation included face validity, content validity, construct validity, and reliability testing. Confirmatory factor analysis was conducted to assess the scale dimensionality using multiple fit indices such as the root mean square error of approximation (RMSEA), the comparative fit index (CFI), the Tucker-Lewis index (TLI), and the standardized root mean square residual (SRMR). Cronbach’s alpha and McDonald’s omega coefficients were used to evaluate internal consistency. Data analysis was performed using Mplus version 8.1.8 and Jamovi version 2.4.14.ResultsThe unidimensional model of the original scale was tested and confirmed confirmatory factor analysis with suitable fit indices: χ² (74, N = 327) = 344.752, p < 0.001; RMSEA = 0.106, CFI = 0.977, TLI = 0.972, and SRMR = 0.033. Both Cronbach’s alpha (0.942) and McDonald’s omega coefficient (0.943) indicated excellent internal consistency. Item factor loadings ranged from 0.620 to 0.907. The known-groups validity analysis revealed no significant association between demographic variables such as age, gender, education, or occupation and the total score of the Nurse Caring Behavior Scale.ConclusionThe Persian version of NCBS can effectively evaluate care behaviors with strong psychometric properties and is applicable in quality audits, practice development, nursing education, and related research.

BackgroundFew validated brief scales are available to measure constructs that may hinder mpox-related prevention and care engagement, such as knowledge and stigma. Both are highly salient barriers to infectious disease care and disease understanding, precursors to evaluating one’s risk and need to, for example, accept vaccination. To address this gap, we developed and validated the Mpox Stigma Scale (MSS) and Mpox Knowledge Scale (MKS).MethodsAs part of a full-scale clinical trial, we offered an optional mpox survey to participants who self-identified as African American or Black, were 18–29 years old, and lived in Alabama, Georgia, or North Carolina (2023, N = 330). We calculated psychometric properties through confirmatory factor analyses (CFA) and applied Comparative Fit Index (CFI), Goodness of Fit Index (GFI), and Tucker-Lewis Index (TLI) values equal to or exceeding 0.90 and Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Square Residual (SRMR) values less than 0.08 to determine adequate model fit. We computed internal reliability using Cronbach’s alpha and calculated Pearson or Spearman correlation coefficients between the MSS and MKS and related variables.ResultsFor the MSS, CFA results showed that the one-factor model fit the data well (χ2(df = 5, N = 330) = 34.962, CFI = 0.97, GFI = 0.99, TLI = 0.94, RMSEA = 0.13, SRMR = 0.03). For the MKS, the one-factor model provided a good fit to the data (χ2(df = 6, N = 330) = 8.44, CFI = 0.99, GFI = 0.99, TLI = 0.95, RMSEA = 0.15, SRMR = 0.02). Cronbach’s alphas were MSS = 0.91 and MKS = 0.83, suggesting good to excellent reliability. The MSS was correlated with the MKS (r = .55, p < .001), stigmatizing attitudes (r = .24, p < .001), attitudes towards mpox vaccination (r=-.12, p = .030), and worry about contracting mpox (r = .44, p < .001). The MKS was correlated with worry about contracting mpox (r = .30, p < .001) and mpox disclosure (r=-.16, p = .003).ConclusionsThe MSS and MKS are reliable and valid tools for public health practice, treatment and prevention research, and behavioral science. Further validation is warranted across populations and geographic locations.Trial RegistrationClinicalTrials.gov NCT05490329.

Food literacy is the ability to understand the nature of food and its level of importance, to obtain, process, analyze, and use information about food. This study aims to translate and cross-culturally adapt the Food Literacy Questionnaire for school children (FLQ-sc) into Turkish and to study its psychometric properties of reliability and validity. The study was conducted with 303 students aged 12-14 in Kayseri, Turkey. A pilot study was conducted with 36 students, and a test-retest was conducted with 219 students, 2weeks after the first study was performed. Data were collected with the sociodemographic data form and FLQ-sc. Linguistic, content, face, and construct validity were evaluated for validity. Cronbach's alpha and intraclass correlation coefficients (ICCs) were calculated for the reliability evaluation. Model validity was tested with confirmatory factor analysis. Root mean square error of approximation (RMSEA), χ2/SD, and goodness-of-fit index (GFI) statistics were in good agreement. Comparative fit index (CFI), Tucker-Lewis index (TLI), and standardized root mean square error of approximation (SRMR) statistics were at acceptable levels (RMSEA = 0.033, χ2/SD = 1.324, GFI = 0.958, CFI = 0.944, TLI = 0.939, SRMR = 0.063). The Cronbach's alpha coefficient for the total scale score was quite good (0.795). The ICC for test-retest reliability was good (0.874) for the total scale score. Conclusion: The Turkish version of the Food Literacy Questionnaire for school children (FLQ-sc) is a valid and reliable measurement tool and can be used to evaluate food literacy levels in Turkish children aged 12-14. What is Known: • It is important to acquire knowledge and skills in food literacy from childhood because the behaviors learned during childhood and adolescence regarding food intake and preparation continue into adulthood. • In addition to the limited scales evaluating the food literacy levels of children, there is no scale evaluating the food literacy levels of Turkish children between the ages of 12 and 14. What is New: • The Turkish version of FLQ-sc is a valid and reliable scale for evaluating the food literacy levels of Turkish school children. • Scale is a suitable tool to ensure the comparison of food literacy levels in different student groups and measure abstract concepts such as education.

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is well known and commonly used to assess young, active patients with ACL injuries. However, this application of the outcome measure has been called into question. There is currently no evidence supporting the structural validity of the KOOS for this patient population. Structural validity refers to whether a questionnaire meant to provide scores on different subscales behaves as intended in the populations of interest. Structural validity should be assessed for all questionnaire measures with multiple items or subscales. Does the KOOS demonstrate adequate structural validity in young, active patients with ACL tears, when evaluated using (1) exploratory and (2) confirmatory factor analyses? Between January 2014 and March 2017, 1033 patients were screened for eligibility in the Stability 1 randomized controlled trial from nine centers in Canada and Europe. Patients were eligible if they had an ACL deficient knee, were between 14 and 25 years old, and were thought to be at higher risk of reinjury based on the presence of two or more of the following factors: participation in pivoting sports, presence of a Grade 2 pivot shift or greater, generalized ligamentous laxity (Beighton score of 4 or greater), or genu recurvatum greater than 10°. Based on this criteria, 367 patients were ineligible and another 48 declined to participate. In total, 618 patients were randomized into the trial. Of the trial participants, 98% (605 of 618) of patients had complete baseline KOOS questionnaire data available for this analysis. Based on study inclusion criteria, the baseline KOOS data from the Stability 1 trial represents an appropriate sample to investigate the structural validity of the KOOS, specifically for the young, active ACL deficient population.A cross sectional retrospective secondary data analysis of the Stability 1 baseline KOOS data was completed to assess the structural validity of the KOOS using exploratory and confirmatory factor analyses. Exploratory factor analysis investigates how all questionnaire items group together based on their conceptual similarity in a specific sample. Confirmatory factor analysis is similar but used often in a second stage to test and confirm a proposed structure of the subscales. These methods were used to assess the established five-factor structure of the KOOS (symptoms [seven items], pain [nine items], activities of daily living [17 items], sport and recreation [five items], and quality of life [four items]) in young active patients with ACL tears. Incremental posthoc modifications, such as correlating questionnaire items or moving items to different subscales, were made to the model structure until adequate fit was achieved. Model fit was assessed using chi-square, root mean square error of approximation (RMSEA) and an associated 90% confidence interval, comparative fit index (CFI), Tucker-Lewis index (TLI), as well as standardized root mean square residual (SRMR). Adequate fit was defined as a CFI and TLI > 0.9, and RMSEA and SRMR < 0.08. Structural validity of the KOOS was not confirmed when evaluated using (1) exploratory or (2) confirmatory factor analyses. The exploratory factor analysis, where the 42 KOOS items were allowed to group naturally, did not reflect adequate fit for a five-factor model (TLI = 0.828). Similarly, the confirmatory factor analysis used to investigate the KOOS structure as it was originally developed, revealed inadequate fit in our sample (RMSEA = 0.088 [90% CI 0.086 to 0.091]). Our analysis suggested a modified four-factor structure may be more appropriate in young, active ACL deficient patients; however, the final version presented here is not appropriate for clinical use because of the number and nature of post-hoc modifications required to reach adequate fit indices. The established five-factor structure of the KOOS did not hold true in our sample of young, active patients undergoing ACL reconstruction, indicating poor structural validity. We question the utility and interpretability of KOOS subscale scores for young, active patients with ACL tears with the current form of the KOOS. A modified version of the KOOS, adjusted for this patient population, is needed to better reflect and interpret the outcomes and recovery trajectory in this high-functioning group. A separate analysis with a defined a priori development plan would be needed to create a valid alternative.

BackgroundHIV-related stigma is associated with poor quality of life and poor healthcare-seeking behaviours in young people living with HIV (YPLHIV) and young people affected by HIV (YPAHIV). India has an estimated 120,000 YPLHIV and 4 million YPAHIV, but efforts to measure HIV-related stigma in them are sparse, impeded by the lack of measuring instruments. Here, we describe the development of the Pune HIV-Stigma Scale (PHSS) and modified-PHSS to measure HIV-related stigma among YPLHIV and YPAHIV, respectively, in India.MethodsWe used data from a mental health study for YPLHIV and YPAHIV aged 15–25 years, conducted at Byramjee Jeejeebhoy Government Medical College & Sassoon General Hospitals, Pune, India, between August 2018 and June 2021. Findings from multiple confirmatory factor analyses and cognitive interviews guided the development of the 12-item PHSS. The modified-PHSS was developed by confirming the structure of the PHSS for YPAHIV. Convergent validity with Center for Epidemiological Studies Depression (CES-D) and UCLA Loneliness scales was assessed using Spearman’s correlation coefficients.ResultsModel fit indices were good for both the PHSS (χ2 = 65.0, df = 48, p value: 0.052; root mean square error of approximation (RMSEA): 0.054; comparative fit index (CLI): 0.980; Tucker–Lewis index (TLI): 0.972; and standardized root mean square residual (SRMR): 0.067), and the modified-PHSS (χ2 = 56.9, df = 48, p value: 0.176; RMSEA: 0.045; CLI: 0.983; TFI: 0.976, and SRMR: 0.078). Spearman’s correlation coefficients indicated low to moderate convergent validity (ρ: 0.03–0.52) across different subscales of the PHSS and modified-PHSS. Cronbach’s alpha for the PHSS was 0.82 and for the modified-PHSS 0.81.ConclusionWe developed the first scales to measure HIV-related stigma among YPLHIV and YPAHIV in India. These concise scales can facilitate measurement of HIV-related stigma more frequently in research studies. We recommend that they be tested in different Indian languages.

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.

Chronic kidney disease-associated pruritus (CKD-aP) is a condition that causes significant distress to people undergoing haemodialysis (HD). It significantly impacts individuals' sleep habits, everyday activities, social interactions, mental health and overall quality of life. A number of tools have been developed to evaluate the severity of pruritus. The 5-D itch scale is one of the most widely used tools for assessing various aspects of pruritus. In Greece, there is no validated and culturally adapted tool to assess pruritus in individuals with CKD receiving HD. Hence, this study aimed to evaluate the reliability and validity of the Greek version of the 5-D itch scale. The English version of the 5-D itch scale was translated into the Greek language according to international guidelines and was cross-culturally adapted in people with CKD on HD (Ν = 120). The intraclass correlation coefficient was used to assess the reliability of the instrument after the test-retest procedure (n = 30). Confirmatory factor analysiswas conducted in order to test how well the 5-D itch scale one-factor model fits the data. Internal consistency reliability was determined by the calculation of Cronbach's alpha coefficient (n = 120). Convergent validity was tested through the correlation with the Kidney Disease Quality of Life Instrument Short-Form (KDQOL-SF) scale and the visual analogue scale. Statistical significance was set at p < 0.05. Analyses were conducted usingIBM SPSS Statistics for Windows, version 26.0 (released 2019, IBM Corp., Armonk, NY). The sample consisted of 120 people with CKD receiving HD (60.0% males, n = 72), with a mean age of 65.7 years (SD ±13 years), of whom 80 individuals reported CKD-aP. Regarding confirmatory factor analysis, this solution had a good model fit (χ2/df = 1.93; root mean square error of approximation (RMSEA) = 0.03; comparative fit index (CFI) = 0.92; Tucker Lewis index (TLI) = 0.93 and standardized root mean square residual (SRMR) = 0.05). The intraclass correlation coefficients were significant (p < 0.001) in all items and over 0.85. Cronbach's alpha for the 5-D itch scale total score was 0.75, indicating good reliability. The reliability index had minor changes after removing its items; thus, no item needed to be removed from the scale. The correlation of the 5-D itch scale with the KDQOL-SF (p = 0.002) indicates the good convergent validity of the scale. The Greek version of the 5-D itch scale is an instrument with good reliability and validity, possessing the potential to be utilised by healthcare professionals for the purpose of the assessment of CKD-aP among Greek-speaking people undergoing HD.
