Model Fit Indices for Random Effects Models: Translating Model Fit Ideas from Latent Growth Curve Models

The latent growth curve modeling (LGM) and random effects modeling (REM) frameworks are analytically and empirically equivalent for intrinsically linear models and used interchangeably for intrinsically nonlinear models. However, while LGM provides overall model fit indices, REM does not. Overall model fit indices are useful because they evaluate how well a specified model fits data. This paper proposes to translate model fit concepts from LGM to REM to help researchers compute overall model fit indices, including the model chi-square (), comparative fit index (CFI), root mean squared error of approximation (RMSEA), and standardized root mean squared residual (SRMR). Three empirical examples were used as illustrations.

The Factors of Millennials’ Continuance Intention to Use Digital Wallets in Indonesia

The growth of digital wallets increases the convenience of consumers in making transactions. The convenience that consumers feel in using digital wallets further increases their consumption. Companies influence the age group, such as millennials, with high potential in using digital wallets. The research emphasized the consumer behavior of millennials in using digital wallets. The study aimed to examine the variables that affected digital wallet users in terms of perceived usefulness, perceived risk, customer attitude, customer satisfaction, and continuance intention to use. The questionnaire was distributed using the G-form using the determination of respondents by purposive sampling. The number of respondents was 276. The measurement of reliability and validity used loadings values, Cronbach’s alpha, Composite Reliability (CR), Average Variance Extracted (AVE), and discriminant validity. In measuring the fit model, the Standardized Root Mean Square Residual (SRMR) value was used. Then, the research used Partial Least Square-Structural Equation Model (PLS-SEM) to test the hypothesis. The results show that perceived usefulness affects customer attitudes toward using digital wallets. Meanwhile, perceived risk has no effect on customer attitudes. Customer attitude impacts customer satisfaction and continuance intention to use digital wallet users directly and indirectly. Moreover, millennials strengthen the influence of customer attitude on continuance intention to use. The effect is negative, meaning that if the age of the millennials increases, it will cause a decreased attitude change towards continuance intention to use digital wallets.

Exploring the Standardized Root Mean Square Residual (SRMR) of Factors Influencing E-book Usage among CCA Students in the Philippines

Early adopters of e-books claimed that e-books encouraged reading, and served as a means of improving individual academic performance. This appears to be unnoticed by academics in the Philippines. Objectives: The primary goal of this work is to conduct a study reporting the standardized root mean square residual (SRMR) of factors influencing e-book usage among students and robustness of the Technology Acceptance Model (TAM). Design: The TAM criteria were used to design an online questionnaire survey focusing on the usefulness, ease of use perception, and attitude toward addressing the hypotheses to the structural equation model for using e-books. The questionnaire’s validity was confirmed by four specialists. The participants are undergraduates at City College of Angeles, Philippines. A total of 348 responses was analyze with aids of SmartPLS version 3.3.2. Results show that these four factors are related to each other and have a strong influence on e-book usage and adoption. Also indicated that perceived usefulness (PU) is the most significant and perceived ease of use (PEU) indicated the least supported. A total 65% variance explained, SRMR 0.08 NFI above 0.9 and RMS_theta 0.12 achieved. Ultimately, a thorough analysis of the study is recommended for future researchers.

Structural validity and internal consistency of the Shoulder Pain and Disability Index in Turkish patients with rotator cuff disease: A proposal of a new version

BackgroundThe Shoulder Pain and Disability Index (SPADI) is a widely used patient-reported outcome questionnaire in patients with shoulder diseases; however, the structural validity and the internal consistency of the Turkish SPADI is unclear in rotator cuff disease. ObjectiveTo assess the internal structure of the Turkish SPADI in patients with rotator cuff disease. MethodsA total of 109 patients with unilateral rotator cuff disease were assessed. The COnsensus-based Standards for the selection of health Measurement INstruments checklist was used for the methodological design of the study. A confirmatory factor analysis was performed, and the model fit was assessed by using the comparative fit index (CFI), the Tucker-Lewis index (TLI), the root mean square error of approximation (RMSEA), and the standardized root mean square residual (SRMR). The factor structure was examined with a principal component analysis. The internal consistency was assessed using Cronbach's alpha. ResultsThe validity of the two subscales was not confirmed. The principal component analysis showed the Turkish SPADI consisted of one factor, and the one-factor model of the Turkish SPADI also was not confirmed. When two items were deleted, the one-factor model of the new version of the Turkish SPADI had a better fit (CFI = 0.978, TLI = 0.971, RMSEA = 0.058, SRMR = 0.043). The internal consistency of the new version of the Turkish SPADI was high (Cronbach's alpha = 0.92, 95% CI = 0.90–0.94). ConclusionsWe suggest that the modified version of the Turkish SPADI should be used for patients with rotator cuff disease. The total score of the modified version should be considered.

Validation and Translation of the Relational Aspect of Care Questionnaire into the Malay Language (RAC-QM) to Evaluate the Compassionate Care Level of Healthcare Workers from the Patient's Perspective.

Background: Compassionate care has been increasingly highlighted in the past few decades worldwide, including in Malaysia. Despite acknowledging its importance, Malaysia still lacks a validated tool that can be used to assess the level of compassionate care from the patient’s perspective. Therefore, this study aims to validate and translate the Relational Aspect of Care Questionnaire (RAC-Q) into the Malay language. Methods: Permission to use and translate the original RAC-Q into the Malay language was obtained. The RAC-Q was then translated into the Malay language following the 10 steps proposed for the translation of a patient-reported outcome questionnaire. A pretest was conducted based on 30 inpatients to assess the appropriateness and clarity of the finalized translated questionnaire. A cross-sectional study was performed based on 138 inpatients from six adult wards of a teaching hospital so as to validate the translated questionnaire. The data were analyzed using R software version 4.1.3 (R Core Team, Vienna, Austria, 2020). The results were presented descriptively as numbers and percentages or means and standard deviations. A confirmatory factor analysis was performed using robust estimators. Results: The analysis showed that the measurement model of the RAC-Q Malay version (RAC-QM) fits well based on several fit indices: a standardized factor loading range from 0.40 to 0.73, comparative fit index (CFI) of 0.917, Tucker–Lewis fit index (TLI) of 0.904, root mean square error of approximation (RMSEA) of 0.06, and a standardized root mean square residual (SRMR) of 0.073. It has good reliability, with a Cronbach’s alpha of 0.857 and a composite ratio of 0.857. Conclusion: The RAC-QM demonstrated good psychometric properties and is valid and reliable based on the confirmatory analysis, and it can thus be used as a tool for evaluating the level of compassionate care in Malaysia.

Psychometric properties of the Chinese version of the sugar-sweetened beverages media literacy scale for undergraduates.

Specific domains of the Sugar-Sweetened Media Literacy Scale (SSM-ML) have been shown to significantly assess sugar-sweetened beverage (SSB) calorie intake in the US population. This study aimed to describe the psychometric properties of the revised Chinese version of the SSB-ML (C-SSB-ML) and evaluate its validity and reliability. Results from 975 undergraduates at two of the largest universities in a province in southwest China showed that Cronbach's alphas for the overall scale, the three dimensions, and two-halves analysis were satisfactory (0.71–0.92). The criterion-related validity of the C-SSB-ML was positively associated with the e Health literacy scale (eHEALS). Confirmatory factor analysis showed that the three-factor model of the C-SSB-ML had adequate fit indices χ2 (153) = 4349.93, p < 0.001; Comparative fit index (CFI), Tucker-Lewis index (TLI), Incremental fit index (IFI) >0.90; Standardized Root Mean Square Residual (SRMR) <0.07; and Root Mean Square Error of Approximation (RMSEA) <0.08. Our findings provide evidence for a valid and reliable tool that can be used to assess sugar-sweetened media literacy in Chinese undergraduates and will help organizations leverage media literacy in strategy formulation to ensure SSB intake is controlled as much as possible through effective efforts on all fronts.

The preliminary reliability investigation revealed a very high internal consistency for the scale.

Ten-Item Lower Extremity Functional Scale (LEFS-10): Instrument Reduction Based on Brazilian Patients With Lower Limb Dysfunction

ObjectiveTo propose a short version of the lower extremity functional scale (LEFS), to compare our short version with the different structures proposed for the LEFS by the specialized literature, and to verify the criterion validity of the best structure of the LEFS identified in our study. DesignCross-sectional observational study. SettingPhysiotherapy clinics. ParticipantsWe included 140 patients with lower limb dysfunction (N=140). InterventionsNone. Main Outcome MeasuresWe used confirmatory factor analysis (CFA), χ2/degree of freedom (DF), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), standardized root mean squared residual (SRMR), Akaike information criterion (AIC), and Bayesian information criterion (BIC). The method of reducing the number of items of the LEFS considered the modification indices and factor loadings. ResultsThe body site most affected by pain was the knee (71.4%), and the most common diagnoses were knee osteoarthritis (55%) and anterior knee pain (11.4%). LEFS reduction generated a 1-dimensional structure of the LEFS with 10 items (LEFS-10). When compared with other structures, the LEFS-10 presented the best fit indices (χ2/DF=1.88, CFI=0.975, TLI=0.968, RMSEA=0.079, and SRMR=0.058) and the lowest values of AIC (3287.063) and BIC (3345.896). LEFS-10 presents a high correlation (Spearman's correlation coefficient [ρ]=0.911, P<.001) with the 20-item LEFS. ConclusionLEFS-10 is the proposal for a short version of the instrument with the most adequate internal structure, in addition to being satisfactorily correlated with the longer version of the instrument.

The reliability, validity and screening effect of the happiness index scale among inpatients in a general hospital

BackgroundThe Happiness Index Scale (HIS) is a newly developed scale by our group to screen for common psychological illnesses among general hospital inpatients. This study aimed to analyze the reliability, validity and screening effect of the HIS and to explore its clinical application.MethodsFrom April 1, 2021, to December 31, 2021, a total of 8405 continuous inpatients were enrolled from different departments of a large tertiary general hospital with 1385 inpatient beds in Guangzhou, Guangdong Province, China. Using a cross-sectional survey design, each participant was assessed with the Patient Health Questionnaire 9(PHQ-9), Generalized Anxiety Disorder 7 items(GAD-7), Athens Insomnia Scale (AIS), Columbia Suicide Severity Rating Scale (C-SSRS) and HIS within 24 h of admission. McDonald's ω coefficient, the Guttman split-half coefficient and the test–retest reliability coefficient were used to evaluate the reliability of the HIS and the construct validity and criterion validity of the validity tests. Scores on the PHQ-9, GAD-7, AIS, and C-SSRS were used as the gold standard tools to analyze the screening effect of the HIS.ResultsThe HIS exhibited very good reliability, with a McDonald's ω coefficient of 0.825, a Guttman split-half coefficient of 0.920 and a test–retest reliability coefficient of 0.745 (P < 0.05). Confirmatory factor analysis showed a satisfactory model fitting index with a χ2/df = 2.602, a root mean squared error of approximation (RMSEA) of 0.014, a standardized root mean square residual (SRMR) of 0.010, a comparative fit index (CFI) of 0.992, and a Tucker–Lewis index (TLI) of 0.983. The correlation coefficient between the total score of each dimension of the scale and the corresponding criterion was 0.854 ~ 0.949 (P < 0.001). The HIS showed a very good distinguishing effect. The average HIS score of inpatients who screened positive for psychological problems was significantly higher than that of inpatients who screened negative for psychological problems (t = 3790.619, P < 0.001). The effect size was very large (Cohens d = 2.695, 95% CI = 2.630 ~ 2.761). Approximately 90.2% of the positive and negative screening results of the HIS were matched with the gold standard tools, with a kappa value of 0.747 (P < 0.001). The screening effect test showed a sensitivity (true positive rate) of 92.9% and a specificity (true negative rate) of 89.5%.ConclusionThe HIS exhibited satisfactory reliability and validity and a clinically meaningful screening effect with a much shorter version compared to the commonly used screening scales. Thus, it could potentially be useful as the first screening step to rule out psychological conditions for inpatients in general hospitals or to remind medical teams of further psychological concerns.

Structural model of the relationship between physical activity and students' quality of life: Mediating role of body mass index and moderating role of gender.

BackgroundAs a country’s future leaders and pioneers, University students must live with healthy habits. In order to achieve a healthy lifestyle, Physical activity and Quality of Life can serve as suitable indices to study. The purpose of the study was to clarify how physical activity (PA), Body mass index (BMI) and gender relate to the quality of life (QOL) of students of Medical Sciences University by using a structural equation model.MethodsThe research was a cross-sectional study. The number of participants was 225 students of the University. The participants answered three questionnaires, including Demographic, International Physical Activity Questionnaire (IPAQ short form), and Quality of Life Questionnaire (SF-12), BMI was calculated by anthropometric measures, as well. The Structural equation model (SEM) method was employed. The Fitness of the proposed pattern was measured using the following indexes: chi-square/degree of freedom ratio (CMIN/DF), Normed Fit Index (NFI), comparative fit index (CFI), the goodness of fit index (GFI), and standardized root mean squared residual (SRMR). In the analysis the significant level was considered as P < 0.05.ResultsPA (r = -0.726, P<0.001) and QOL (r = -0.405, P<0.001) have significantly inverse relationship with BMI, whereas the QOL and PA were proven to be positively related (r = 0.357, P<0.001). Moreover, the results signify gender as a moderator in the relationship between PA and QOL (Δχ2 (10) = 19.903, P = 0.030) and also the mediatory role of BMI among students. BMI affects the QOL in men (P < 0.001, β = -0.307) more in compare to women women (P = 0.324, β = -0.158).ConclusionStudy findings supported the research hypothesis. Gender exhibited moderating role in the relationship between PA and QOL, considering the mediating role of BMI.

Validity and reliability study of clinician attitude towards rural health extension program in Ethiopia: exploratory and confirmatory factor analysis

BackgroundThe Ethiopian health extension program (HEP) is an innovative community-based strategy aimed at disease prevention and health promotion. While health extension workers (HEWs) are its front-line workers, the involvement of clinicians remains an integral part. The goals of this study were to: (1) assess the correlation of clinician attitude with predictors and (2) assess the reliability and validity of the survey instrument.MethodsA cross-sectional study design was utilized to collect data from a sample of 1239 clinicians using 28 items of attitude questions. Exploratory factor analysis (EFA) was applied to create the latent variables. Oblique Promax type rotation with factor loading (> 0.5) was used. Cronbach’s alpha was used to assess reliability, with a level of > 0.7 suggesting good reliability. Confirmatory factor analysis (CFA) was undertaken, with the values of Root Mean Square Error Administration (RMSEA) < 0.08, Standardized Root Mean Square Residual (SRMR) < 0.05, comparative fit index (CFI) 0.9–0.95, and Tucker-Lewis index (TLI) 0.9–0.95 suggesting acceptable model fit. A linear regression analysis was conducted.ResultsEFA produced two latent variables which explained 93.2% of the total variance. The latent variables were labeled as perceived attitude towards the skill of HEWs (F1), and perceived attitude towards the impact of HEP (F2). Internal reliability for the 28 items was reported with a Cronbach’s alpha of 0.94, and for F1 and F2 it was 0.91 and 0.90, respectively. CFA was done and RMSEA was reported at 0.04, SRMR was 0.03, and CFI and TLI were each 0.97. The value of clinician attitude increased by 3.5, 95% CI (1.5, 5.3), P-value < 0.001 for those who have been exposed to the HEP program than non-exposed. Similarly, clinician attitude was lower for degree holders compared to those with diplomas by − 2.7, 95% CI (− 4.4, − 0.94), P-value < 0.002.ConclusionClinician attitude increased as exposure to HEP increased. Clinician attitude towards HEP has two latent variables. Furthermore, the assessment tool demonstrated good reliability and validity. In conclusion, it is worthy valued for clinicians to receive orientation about HEP, and researchers and program evaluators can use this assessment tool.

Development and validity of the subjective training quality scale

ABSTRACT This study aimed to define, develop, and validate a subjective scale of training quality. Two related studies were used to 1) define training quality and 2) develop and validate a subjective scale. Part One: a purposive sample of 15 sub-elite (i.e. national) and elite (i.e. international) swimmers participated in one, 20-30-min semi-structured interview. Thematic analysis of interview responses established three constructs to define training quality. These were the physical, technical, and mental aspects of training. Part Two: development of the Subjective Training Quality (STQ) scale based on the three constructs identified in Part One. 252 sub-elite and elite athletes, across eight sports completed the STQ scale. Cronbach’s alpha (α) assessed internal consistency, histogram plot analysis assessed face validity, and confirmatory factor analysis (CFA) compared physical, technical, and mental constructs with training quality. Root mean square error of approximation (RMSEA) and standardised root mean square residual (SRMR) evaluated CFA quality of fit. Physical, technical, and mental constructs demonstrated a high “acceptable” level of internal consistency (α = 0.85) and excellent face validity. Comparatively, the CFA quality of fit was “excellent” (RMSEA = <0.01 “good”, SRMR = 0.00 “perfect”). The STQ scale demonstrated excellent internal consistency and face validity, establishing capacity to monitor training quality. The STQ scale could be used in conjunction with traditional training monitoring tools to provide additional insight into athlete’s training quality. Further investigation is required to determine how the STQ scale may interact with subjective and objective training performance measures, and how it could be incorporated into daily training monitoring. Highlights Athletes perceive the subjective training quality (STQ) scale adequately represents the physical, technical, and mental constructs of training quality. Excellent internal consistency and confirmatory factor analysis fit demonstrates the STQ scale is an effective tool to monitor training quality. With additional validation, the STQ scale could be used in conjunction with traditional load monitoring tools to provide greater insight to an athlete’s training response, and subsequently inform training prescription.

Factor structure of the Maslach Burnout Inventory Human Services Survey in Spanish urgency healthcare personnel: a cross-sectional study

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.

Psychometric properties and clinical utility of COVID-19-related distress scale among children and adolescents with Disabilities

BackgroundThe aim was to estimate the psychometric properties of the COVID-19-related distress scale in our society, as well as verifying the global structure of the COVID-19-related distress scale through exploratory factor analysis and the confirmatory factor analysis model for the dimensions prepared in the light of previous studies and the general factor model. MethodsThe study follows the design of the exploratory cross-sectional studies by applying a scale electronically using the Google Forms tool. Construct validity was evaluated using confirmatory factor analysis, exploratory factor analysis, and content validity. Pearson product-moment correlation, Cronbach's alpha reliability coefficient, and test-retest methods were used to evaluate reliability. ResultsIn the analysis made for internal consistency in the reliability study of the scale, the Cronbach's alpha reliability coefficients were determined as α = 0.93 for the physical dimension subscale, 0.90 for the psychological and emotional dimension, 0.92 for cognitive dimension, 0.91 for the social dimension, 0.92 for behavioral dimension, 0.87 for living Dimension and 0.94 for the whole scale. The total number of items on the scale is 62. It is clear that the items of the scale explained 55.49 % of the variance of the correlation matrix between the items, which indicates that the scale has an appropriate degree to extract the variance that explains COVID-19-related distress. The fit indices were found to be Chi square = 862.30 (p < .001), degree of freedom = 210 (χ2 = 862.30; df = 210, χ2/df = 4.10), root mean square error of approximation (RMSEA) = 0.07 (p < .05) standardized root mean- square residual (SRMR) = 0.05, comparative fit index (CFI) = 0.92, non-normed fit index (NNFI) = 0.95, goodness of fit index (GFI) = 0.95, and adjusted goodness of fit index (AGFI) = 0.94. ConclusionsThe COVID-19-related distress scale is an easy to administer, valid, and reliable instrument to assess COVID-19-related distress. This instrument can be a helpful tool informing us about distress related to COVID-19 and hence may prevent adverse long-term consequences arising due to pandemic.

Exploring academic procrastination among nursing students during pandemic COVID-19

Introduction: An instrument that is frequently used to gauge academic procrastination is the Procrastination Assessment Scale for Students (PASS). During covid-19 pandemic the chance to get more into procrastination mode is higher because while students is studying at home they have something distracted their mind such as watching movie, using social media and the others things. The objective of this study was to evaluate the constructs of validity and reliability of the procrastination assessment scale for nursing students during the pandemic COVID-19 are examined. Method: It is a cross sectional study where distributed to 416 nursing students and the data taken by stratified sampling. The scale consists of two part, part one is area of procrastination had 18 items and second part is reason for procrastination had 26 items. The data was analyzed with Stata. Results: The reliability of first part was 0.6615 and the second part was 0.9136. The model was acceptable where root mean squared error of approximation (RMSEA) = 0.108, standardized root mean square residual (SMRS) = 0.063, comparative fit index 0.957, CI 90%. Conclusion: Based on the investigation, the dimensions and indicators that make up the academic procrastination construct are credible and valid ways to assess it among Indonesian nursing students.

Goal orientation motivation theory in surgical trainees: a multi-institutional validation study of the GO-ST scale

PurposeGoal orientation is an important psychological construct which describes the nature of an individual’s intrinsic motivation for learning in terms of mastery and performance. Research on goal orientation in primary school through college-level learners has consistently demonstrated a relationship between goal orientation and learning outcomes, test scores, motivation, feedback incorporation and burnout. The aim of this study was to create and validate a novel instrument to measure goal orientation motivation in surgical trainees.MethodsA validation study of a novel survey instrument specific for surgical trainees was conducted at five general surgery training programs across the United States over the course of a single academic year. A 14 item goal orientation in surgical trainees (GO-ST) instrument was developed and responses were scored on a 5-point Likert scale measuring frequency over a month. Exploratory and confirmatory factor analyses were performed.ResultsA total of 144 residents participated for an 87.8% response rate. Confirmatory factory analysis using 3 domains yielded a final instrument with ten total questions. The Comparative Fit index (CFI) of this model was 0.950, the Goodness of Fit index (GFI) was 0.920, and the Standardized Root Mean Square Residual (SRMR) was 0.064.ConclusionsUsing the goal orientation theory of motivation, The GO-ST instrument was successfully developed to measure the three domains of goal orientation, mastery, performance approach, and performance avoid in surgical trainees. The ability to distinguish the way in which a learner internalizes educational opportunities in terms of motivation paves the way to understanding a new perspective on wellness, mastery and the clinical learning environment.

Development and validation of a maternal anxiety for neonatal jaundice scale in China

BackgroundMaternal anxiety induced by neonatal jaundice has adverse effects on maternal and infant health, but there was no specific tool to identify the anxiety level of mothers. This study aims to develop a Maternal Anxiety for Neonatal Jaundice Scale (MANJS) and to validate it in the target population.MethodsAn initial 11-items MANJS was developed through literature review, expert panel consultation, and a pilot-test. Subsequently, mothers of neonates with jaundice were recruited from the Maternal and Child Health Hospital of Hainan Province, China, from June to December 2018, for a formal questionnaire survey. Based on the data collected, the scale was validated for construct validity, convergent validity, discriminant validity, content validity, and internal consistency reliability after the items screening.ResultsThe reliability and validity of MANJS were validated in 1127 mothers of jaundiced neonates. After the item with cross-loadings was removed using exploratory factor analysis, MANJS consisted of two dimensions and 10 items, with a cumulative variance contribution of 74.36% and factor loadings above 0.6 for all items. The confirmatory factor analysis identified three items with cross-factor loading or error correlation and then they were removed orderly. The further confirmatory factor analysis showed a good construct validity for the 7-item MANJS, with standardized root mean square residual (SRMR) = 0.029, root mean square error of approximation (RMSEA) = 0.068, comparative fit index (CFI) = 0.961, Tucker-Lewis index (TLI) = 0.937, incremental fit index (IFI) = 0.961, normed fit index (NFI) = 0.954, goodness of fit index (GFI) = 0.998, adjusted goodness of fit index (AGFI) = 0.996, respectively. The average variance extracted values (AVE) of the two factors were 0.80 and 0.72, and the combined reliability (CR) were 0.94 and 0.88, respectively. Cronbach’s alpha was 0.90 for the MANJS, and split-half reliability was 0.72.ConclusionsMANJS was demonstrated to have satisfactory reliability and validity in evaluating maternal anxiety caused by neonatal jaundice among Chinese postpartum women.

Development of shortened HIV-related stigma scales for young people living with HIV and young people affected by HIV in India

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.
