Translation and psychometric validation of the Korean version of the academic nurse self-efficacy scale for Korean bachelor-level nursing students

Objective:This study aimed to translate the Academic Nurse Self-Efficacy scale(ANSE),assess its appropriateness for use in Korean nursing students,and evaluate the Korean Version of the Academic Nurse Self-Efficacy scale’s(K-ANSE)validity and reliability.Methods:The data of 444 nursing college students at 10 universities across the country were collected from November 1,2020 to June 8,2021.The K-ANSE was analyzed utilizing SPSS 25.0 and AMOS 25.0 programs.The K-ANSE’s content validity,construct validity,convergent/discriminant validity,criterion-related validity,and reliability were evaluated.Results:Internal emotion management,auto-regulatory behavior,external emotion management,and sociality were established.The Cronbach’sαfor the overall scale was 0.87,and that of the 4 subscales ranged from 0.70 to 0.89.Conclusions:The Korean version of the ANSE seems to be a valid and reliable instrument to measure Korean bachelor-level nursing students.

Validity,Reliability,and Measurement Invariance of the Thai Smartphone Application-Based Addiction Scale and Bergen Social Media Addiction Scale

Background:In recent years,there has been increased research interest in both smartphone addiction and social media addiction as well as the development of psychometric instruments to assess these constructs.However,there is a lack of psychometric evaluation for instruments assessing smartphone addiction and social media addiction in Thailand.The present study evaluated the psychometric properties and gender measurement invariance of the Thai version of the Smartphone Application-Based Addiction Scale(SABAS)and Bergen Social Media Addiction Scale(BSMAS).Method:A total of 801 Thai university students participated in an online survey from January 2022 to July 2022 which included demographic information,SABAS,BSMAS,and the Internet Gaming Disorder Scale-Short Form(IGDS9-SF).Results:Confirmatory Factor Analyses(CFAs)found that both the SABAS and BSMAS had a one-factor structure.Findings demonstrated adequate psychometric properties of both instruments and also supported measurement invariance across genders.Moreover,scores on the SABAS and BSMAS were correlated with scores on the IGDS9-SF.Conclusion:The results indicated that the SABAS and BSMAS are useful psychometric instruments for assessing the risk of smartphone addiction and social media addiction among Thai young adults.

Transcultural Validation and Adaptation of the Academic Stress Questionnaire (CEA) in Students of Puerto Rico

Background: There are multiple questionnaires to measure academic stress in university students, which have been used in nursing students. In Puerto Rico, a questionnaire valid in content and reliability was required to measure the variable of academic stress in nursing students. Purpose: The aim of this study was to adapt transculturally and validate the Academic Stress Questionnaire (CEA) for its use in Puerto Rico. Materials and Methods: Used for the first phase of this study consisted in the evaluation of the validity of content and appearance, whereas the second phase was the actual administering of the questionnaire to 20 (twenty) nursing students, to pilot test its internal consistency using the Cronbach’s α test. Results: Validity of content and appearance allowed for the modification of the questionnaire into one, consisting of 42 items, thus eliminating 34 premises from the original 76 items the questionnaire was composed of. Furthermore, the appearance of the questionnaire was modified by placing the measuring scales in columns, adapting social, demographic, and academic data to the required Puerto Rican reality. The sections meant to measure the academic stress variables were left intact, except for the linguistics adaptation, which was accomplished by a team of experts in the Spanish language. With an α global of 0.80 and coefficients larger than 0.7 in the multi-item sub scales, which oscillated between 0.750 and 0.860, the questionnaire provides a high reliability. Conclusion: Although the values reported in this study are somewhat lower than previous research, they were comparable the Cronbach’s Alpha coefficients reported by Cabanach, in which the numbers reported are considered high (α > 0.70) which show acceptable confiability of the subscales included in the study and a high degree of consistency and thus can be relied upon in future research. In synthesis, the Academic Stress Questionnaire (CEA) modified and adapted, thoroughly fulfills the established criteria of confiability and validity to evaluate academic stress of Puertorrican nursing students.

Validation of the Portuguese version of the social isolation scale with a sample of community-dwelling older adults

Objectives The aim of this study was to analyze the psychometric properties(reliability and validity)of the Social Isolation Scale(SIS)in a sample of Portuguese community-dwelling older adults.Methods A transversal descriptive study was carried out with a convenience sample of 250 community-dwelling older adults(≥65 years).The survey comprised a sociodemographic questionnaire,SIS,Geriatric Depression Scale-4(GDS-4),6-item Lubben Social Network Scale(LSNS-6),a loneliness self-assessment question,and Satisfaction with Life Scale(SWLS).Construct validity(confirmatory factor analysis)and convergent validity were analyzed,and ISI internal reliability(composite reliability),external reliability(test-retest,intraclass correlation coefficient)and inter-rater reliability(Cohen’s kappa coefficient)were evaluated.Results Confirmatory factor analysis showed a two-factor model with an excellent index of fit.The SIS showed significant correlations with LSNS-6(rs=0.47),SWLS(rs=0.26),the loneliness self-assessment question(rs=0.35),and GDS-4(rs=−0.16).SIS composite reliability was good(0.708).The inter-class correlation coefficient varied from 0.84 to 0.98.The Cohen’s kappa coefficient ranged from 0.936 to 1.Conclusions SIS has been shown to be a valid and reliable instrument for assessing social isolation among Portuguese community-dwelling older adults.Healthcare professionals,particularly nurses working in community settings,can use SIS to assess social isolation in older adults to design,implement,and evaluate interventions.

Translation of Well-being Assessment Instruments in African Contexts: A Mapping Review and Future Directions

A fundamental requirement for proper measurement of well-being in diverse contexts is the appropriate translation of well-being measures into the languages spoken by the specific population.The aim of this paper is to identify measures of well-being that have been translated into African languages up to the year 2019 and make suggestions for researchers who are faced with the challenge of translating well-being instruments into local languages.Online databases were searched to identify published studies reporting the translation of well-being instruments into African languages.Some researchers were further contacted and requested to provide relevant studies.A total of 352 publications were retrieved and 44 translated measures met the inclusion criteria.Findings showed that all the translated African language versions of existing measures were published between 2006 and 2019.Although the published translations were increasingly widespread,the distribution of available studies was uneven,with very low published translation activity in East and North Africa and a preponderance of publications on translated instruments in South Africa.The authors suggest deriving population norms for relevant translations;increasing funding and other resources for translation projects;developing cross-national collaborations on translations;and making the translated versions of well-being instruments more accessible for use by other researchers.

Development and Psychometric Assessment of the Dyslexia Awareness Instrument in Teachers

Dyslexia is a specific learning disability that is neurobiological in origin.It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities.Teachers may not be very sure about the definition of dyslexia and generally struggle to tell the difference between dyslexic learners and slow learners.Developing the DyAwI may provide an important psychometric assessment tool in determining the awareness level of the teacher and being able to make this distinction.A descriptive,explorative design was used in this study.The study consisted of two main phases.In the first phase,in order to develop the instrument,a literature review and a pilot study on 20 primary school teachers were carried out,and in line with expert opinions,the content validity index was calculated.In the second stage,exploratory and confirmatory factor analyses were carried out to identify the construct validity and reliability.The study included 182 primary school teachers for the second stage.The KMO and Bartlett test values,which determine the suitability of DyAwI for factor analysis,were found to be 0.77 and 0.000,respectively.The overall Cronbach’s alpha value of DyAwI was 0.75.As a result of the assessment of its construct validity,the scale consisted of 2 factors and 14 items.The findings of the study show that the tool is reliable and sufficient.The instrument is easy to understand,and this tool can determine the dyslexia awareness levels of teachers.DyAwI could promote teachers’awareness of dyslexia and support the early identification of primary school students with dyslexia.It is believed that,thanks to the data obtained from the instrument,teachers will be able to decide on an educational assessment of a student with reading difficulties more quickly.

Development of an Arabic version of the National Eye Institute Visual Function Questionnaire as a tool to study eye diseases patients in Egypt

AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.

Psychometric Properties of the Swedish Version of the Fear of Complications Questionnaire

Objectives: To translate and evaluate the psychometric properties of the Swedish version of the Fear of Complications Questionnaire. Design: Cross-sectional study design and scale development. Settings: Totally, 469 adults (response rate 63.5%) with Type 1 diabetes completed the questionnaires. Participants were recruited from two university hospitals in Sweden. Participants: Eligible patients were those who met the following inclusion criteria: diagnosed with Type 1 diabetes, diabetes duration of at least 1 year and aged at least 18 years. Methods: The Fear of Complications Questionnaire was translated using the forward-backward translation method. Factor analyses of the questionnaire were performed in two steps using both exploratory and confirmatory factor analysis. Convergent validity was examined using the Hospital Anxiety and Depression Scale and the Fear of Hypoglycaemia Fear Survey. Internal consistency was estimated using Cronbach’s alpha. Results: Exploratory factor analysis supported a two-factor solution. One factor contained three items having to do with fear of kidney-related complications and one factor included the rest of items concerning fear of other diabetes-related complications, as well as fear of complications in general. Internal consistency was high Cronbach’s alpha 0.96. The findings also gave support for convergent validity, with significant positive correlations between measures (r = 0.51 to 0.54). Conclusion: The clinical relevance of the identified two-factor model with a structure of one dominant subdomain may be considered. We suggest, however a one-factor model covering all the items as a relevant basis to assess fear of complications among people with Type 1 diabetes.

Psychometric properties and characteristics of the Diabetes Self Management Scale

Objective:Assessing diabetes self care management is essential for nursing care for diabetes.There is a need to have valid and reliable scales that assess the actual performance of diabetes self management,The purpose of this study was to revise and conduct psychometric testing and analysis of the Diabetes Self Management Scale(DSMS).Methods:A cross-sectional methodological design was used.A convenience sample was used and 78 adults with diabetes and taking insulin from five sites in the Midwest area of the U.S participated in the study.Reliability analysis was done using Ferketich techniques to make decisions about whether any given item should be retained or deleted.Results:A descriptive analysis for the 60 items of the scale was conducted;several items had low variability compared to the other items on the scale.The correlation matrices showed that a total of 20 items had poor item characteristics.These 20 items were deleted resulting in developing 40-item version of the scale.The 40-item scale had high level of internal consistency(Cronbach'sα=0.947).The validity testing of the 40-item scale was guided by the Research Model for Diabetes Self Care Management;results were congruent with the model and showed strong correlation with self efficacy,moderate correlation with self care agency,and weak correlation with diabetes knowledge.Conclusion:The items and the scale(DSMS)have undergone careful psychometric testing.The 40-item DSMS is a reliable and valid instrument to measure diabetes self care management among people with diabetes.

Burnout among Lebanese nurses: Psychometric properties of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS)

Background: Burnout is a mental condition defined as a result of continuous and long-term stress exposure, particularly related to psychosocial factors at work. This paper aims to examine the psychometric properties of the Maslach Burnout Questionnaire (MBI-HSS) for validation of use in Lebanon, and to describe burnout and associated factors amongst nurses in Lebanon especially the gender and employment sector. Methods: The psychometric properties of the Arabic version of MBI-HSS were studied amongst a sample of 200 nurses. In this descriptive study, survey data were collected from private and public hospitals. The data were analyzed by means of descriptive statistics and multivariate analysis. Results: The results indicated satisfactory reliability through internal consistency for all three scales of the MBI-HSS. The factor analysis was quite satisfactory. Most of staff had scores which indicated they were burnt out. Nearly three quarters (77.5%) reported emotional exhaustion, 36.0% reported depersonalization while almost one third (33.0%) experienced reduced personal accomplishment. Burnout increases for 30-39 years age groups. Married nurses had significantly higher emotional exhaustion. Depersonalization was highest among nurses in private sector, and personal accomplishment was highest among nurses in public sector. Depersonalization proved to be higher in night and rotating shift nurses. Depression, backache, and headache were predictors of burnout. Conclusion: Findings indicate that the main psychometric properties of reliability and validity of the Arabic version of MBI-HSS appear to be satisfactory. Burnout is particularly prominent and severe in the nurses working population. The implications of these findings for interventions that reduce burnout and promote nursing mental health are therefore in the interest of employers, governments and policy makers.

Reliability and validation of the Arabic version of the Conditions for Workplace Effectiveness Questionnaire-Ⅱ

Objective:This study aimed to examine the psychometric properties of the Conditions for Workplace Effectiveness Questionnaire-Ⅱ-Arabic Version(CWEQ-Ⅱ-AV),which measures structural empowerment among nurses.To enhance the usability and credibility of the CWEQ-Ⅱ among researchers within Arabicspeaking countries,a valid and reliable Arabic version of the measure is necessary.Methods:A cross-sectional research design was used.From December 2018 to June 2019,275 nurses working in 4 hospitals participated in the study.Reliability was assessed by examining internal consistency and split-half reliability.A confirmatory factor analysis was performed to evaluate the factor structure of the CWEQ-Ⅱ-AV.Results:The psychometric properties of the CWEQ-Ⅱ-AV were excellent regarding the six-factor model(opportunity,information,resources,support,formal power,and informal power).The results showed the following fit indices meet the criteria set a priori:comparative fit index(CFI)=0.96,root mean square of error approximation(RMSEA)=0.06,andХ^(2)/df=2.08.Cronbach's a coefficient was 0.95 for the total questionnaire and ranged between 0.83 and 0.89 for the individual subscales.The split-half reliability was 0.91 for the total questionnaire and ranged from 0.83 to 0.87 for individual subscales.Conclusion:This study provides evidence that CWEQ-Ⅱ-AV is both a reliable and valid measure of structural empowerment among Arab nurses.

Quality of Life of Patients with Knee Osteoarthritis with Questionnaire OAKHQOL (OsteoArthritis of Knee Hip Quality of Life) in Rheumatology Consultation in Burkina Faso (West Africa)

Objective: To study the quality of life of patients with knee OA with the questionnaire OAKHQOL (OsteoArthritis of Knee Hip Quality Of Life). Patients and Methods: This was a cross-sectional study over a period of six months, in patients with symptomatic knee osteoarthritis. All patients met the clinical and radiological criteria of the ACR. The OAKHQOL questionnaire was used to investigate the quality of life of patients. Results: One hundred and six patients were included. There were 94 (88.7%) women and 12 (11.3%) men with a sex ratio of 0.12. The average age of patients was 55 ± 10.4 years. The average pain intensity was 55.1 ± 22.4. The majority of patients (69.8%) had stage 3 of Kellgren and Lawrence classification. The dimension “pain” had the lowest normalized score (60.6). There was a significant correlation between the age range of 30 to 40 years and declining mental health (49.5) . The patients with over 60 years of age had a decrease in pain tolerance and reduced social activities. Lequesne score was associated with severe all dimensions except “social support” of the patient. Conclusion: The knee has an impact on quality of life of patients followed in rheumatology by OAKHQOL questionnaire.

Validation of the Arabic version of the Ocular Surface Disease Index Questionnaire

AIM: To develop an Arabic version of the ocular surface disease index(OSDI) and to assess its reliability and validity.METHODS: A cross sectional study was carried out to validate the Arabic version of the OSDI questionnaire. Initially, forward-backward translation was used to translate the English version of OSDI into Arabic. The translated questionnaire was tested for equivalence and cultural adaptability. Totally 200 subjects were then recruited from a non-clinical population and asked to complete the Arabic version of the OSDI(ARB-OSDI). The reliability of the questionnaire was assessed using Cronbach’s-α. A subgroup of 30 participants was asked to complete the questionnaire on two occasions to test the test-retest reliability.RESULTS: A total of 200 participants were enrolled in the study. The average age of the study participants was 31.21±13.2 y and 57% were male. An acceptable internal consistency level for the ARB-OSDI questionnaire measured by Cronbach’s-α was revealed. All questions showed good internal consistency. Test-retest reliability analysis revealed good stability(interclass correlation coefficient, r=0.832, P<0.001). The construct validity for the questionnaire was also high.CONCLUSION: The ARB-OSDI questionnaire shows very good psychometric properties(acceptable internal consistency and test-retest reliability). That makes the questionnaire a valid potential tool to use in Arabic-speaking countries to monitor symptoms of dry eye disease in a larger population.

Development of Mental Health Literacy Scale for Depression Affecting the Help-Seeking Process in Health Professional Students

Despite depression being a global mental health disorder,many people with depression do not seek psychiatric help.In particular,it has been reported that only 15.7%of medical students seek treatment.A longer duration of untreated illness(DUI)leads to clinically poor results.To shorten the DUI,the mental health literacy(MHL)with regard to depression needs to be improved,although it is unclear which MHL components will improve the help-seeking process.Additionally,the existing MHL scale for depression is poorly validated for structural validity.Therefore,the purpose of this study was to develop an MHL scale for depression with verified reliability and validity(particularly structural validity)and verify its relationship with the help-seeking process.For this purpose,we adapted the mixed research method.First,we conducted a systematic literature review on MHL scales for depression to prepare a draft scale with content validity.Second,we conducted semi-structured interviews on MHL with outpatients with depression.Consequently,78 questions on MHL for depression were extracted.Third,to develop our scale,we verified the reliability and validity of these questions with 782 health professional students.The sample size was 780 and data collection was performed by collective survey method.It was conducted in 2018 in Japan.To verify the factor structure,exploratory and confirmatory factor analyses were conducted.We also examined the internal consistency,test-retest reliability,and criterion-related validity.The exploratory factor analysis revealed a three-factor structure(recognition of depression symptoms,helpseeking preferences,and depression onset possibility)with 10 items.According to the confirmatory factor analysis results,the goodness of fit indicators had a good fit.The internal consistency,test-retest reliability,and criterion-related validity had good values.Fourth,the relationship between the MHL of depression and other factors affecting the help-seeking process was examined using structural equation modelling.The same sample size(as above)was applied.All three components of the MHL of depression influenced‘recognition of depression’.In particular,depression onset possibility had the greatest impact on the help-seeking process.Whereas,the MHL of depression had little or no influence on‘intention of consultation’and‘psychiatric consultation’(second and third steps of help-seeking).The largest influence on psychiatric consultation was the recommendation of consultation from others.The multiple correlation coefficients were the recognition of depression,R2=0.33;intention of consultation,R2=0.43;and psychiatric consultation,R2=0.36;and the model was a good fit.This study identified the specific components of the depression MHL that influence the help-seeking process.Subsequently,it is necessary to provide specific MHL education to health professional students,their families,university staff,and teachers.

The Brunel Mood Scale Rating in Mental Health for Physically Active and Apparently Healthy Populations

There is a positive relationship between mood states and mental health. The aim of the present study was to investigate the construct validity and internal consistency of the Brunel Mood Scale (BRUMS) for use with different populations, which are physically active and apparently healthy. Measures were obtained from 1295 male (N = 709, 34 ± 20 years, mean ± SD) and female (N = 576, 43 ± 24 years, mean ± SD) volunteers. Factor analysis was used, verifying that six factors (components) accounted for 62.65% of the total variance of the scale. The Varimax method with Kaiser Normalization for the rotation of the factors for the main components, and it was observed that the 24 scale items loaded on six mood factors (anger, depression, tension, vigor, fatigue, and confusion). Internal consistency was good for all the factors identified. We suggest that the results provide some support for validity of the BRUMS for use with different populations, which are physically active and apparently healthy.

Testing Rating Scale Unidimensionality Using the Principal Component Analysis (PCA)/<i>t</i>-Test Protocol with the Rasch Model: The Primacy of Theory over Statistics

Psychometric theory requires unidimensionality (i.e., scale items should represent a common latent variable). One advocated approach to test unidimensionality within the Rasch model is to identify two item sets from a Principal Component Analysis (PCA) of residuals, estimate separate person measures based on the two item sets, compare the two estimates on a person-by-person basis using t-tests and determine the number of cases that differ significantly at the 0.05-level;if ≤5% of tests are significant, or the lower bound of a binomial 95% confidence interval (CI) of the observed proportion overlaps 5%, then it is suggested that strict unidimensionality can be inferred;otherwise the scale is multidimensional. Given its proposed significance and potential implications, this procedure needs detailed scrutiny. This paper explores the impact of sample size and method of estimating the 95% binomial CI upon conclusions according to recommended conventions. Normal approximation, “exact”, Wilson, Agresti-Coull, and Jeffreys binomial CIs were calculated for observed proportions of 0.06, 0.08 and 0.10 and sample sizes from n= 100 to n= 2500. Lower 95%CI boundaries were inspected regarding coverage of the 5% threshold. Results showed that all binomial 95% CIs included as well as excluded 5% as an effect of sample size for all three investigated proportions, except for the Wilson, Agresti-Coull, and JeffreysCIs, which did not include 5% for any sample size with a 10% observed proportion. The normal approximation CI was most sensitive to sample size. These data illustrate that the PCA/t-test protocol should be used and interpreted as any hypothesis testing procedure and is dependent on sample size as well as binomial CI estimation procedure. The PCA/t-test protocol should not be viewed as a “definite” test of unidimensionality and does not replace an integrated quantitative/qualitative interpretation based on an explicit variable definition in view of the perspective, context and purpose of measurement.

Swedish Hospital Survey on Patient Safety Culture— Psychometric properties and health care staff’s perception

This study examined the psychometric properties of the Swedish and the original version of the Hospital Survey on Patient Safety Culture within a Swedish hospital setting and described health care staff’s perceptions of patient safety culture. A web-survey was used to obtain data from registered nurses, enrolled nurses and physicians (N = 1023). Psychometric properties were tested using Confirmatory Factor Analysis and internal consistency using Cronbach’s alpha coefficient. Root mean square error of approximation and other fit indices indicated psychoFmetric properties for both versions to be acceptable. Internal consistency for the dimensions varied between 0.60 and 0.87. Staff scored the dimension “Teamwork Within Units” highest and the dimension “Hospital Management Support” the lowest. The safety was graded as very good or excellent by 58.9% of the respondents and one third had reported more than one event in the past 12 months. The questionnaire is considered to be useful for measuring patient safety culture in Swedish hospital settings. Managers have a great responsibility to work with improving patient safety culture.

Validity and reliability of eating disorder assessments used with athletes： A review

Background： Prevalence of eating disorders （EDs） among college-aged athletes has risen in recent years. Although measures exist for assessing EDs, these measures have not been thoroughly reviewed in athletes. This study reviewed the validity and reliability evidence of the commonly used measures for assessing EDs in athlete populations aged 18--26 years. Methods： Databases were searched for studies of regarding ED on male and/or female athletes. Inclusion criteria stated the study （a） assessed EDs in an athlete population 18--26 years of age and （b） investigated EDs using a psychometric measure found valid and/or reliable in a non- athlete population and/or athlete population. Results： Fifty studies met the inclusion criteria. Seven and 22 articles, respectively, studied EDs behaviors in male and female athletes whereas 21 articles studied EDs in combined-gender samples. The five most commonly used measures were the Eating Attitudes Test （EAT）, Eating Disorder Inventory （EDI）, Bulimia Test-Revised （BULIT-R）, Questionnaire for Eating Disorder Diagnosis （QEDD）, and the Eating Disorder Examination Questionnaire （EDE-Q）. Conclusion： Only seven studies calculated validity coefficients within the study whereas 47 cited the validity coefficient. Twenty-six calculated a reliability coefficient whereas 47 cited the reliability of the ED measures. Four studies found validity evidence for the EAT, EDI, BULIT-R, QEDD, and EDE-Q in an athlete population. Few studies reviewed calculated validity and reliability coefficients of ED measures. Cross- validation of these measures in athlete populations is clearly needed.

The Chinese version of the revised Diabetes Distress Scale for adults with type 2 diabetes:Translation and validation study

Objectives:This study aimed to translate the revised 17-item Diabetes Distress Scale(DDS17,2017)into mandarin(simplified)Chinese and validate the Chinese version of DDS17(C-DDS17,2021)among adult patients with type 2 diabetes in China.Methods:A scale translation and cross-sectional validation study was conducted.The DDS17 was translated into mandarin(simplified)Chinese through a five-step process:authorization,forward translation,synthesis,back translation,and amendment.During this session,59 patients assessed the understandability and readability of the translated scale.From June 7 to September 4,2021,a cross-sectional study that adhered to the COSMIN checklist was conducted with 400 individuals with type 2 diabetes from three Class A tertiary comprehensive hospitals in Beijing,China.The content,construct,convergent,discriminant validity,and reliability(Cronbach’s a coefficient and item-total correlation coefficients)of the C-DDS17 were evaluated.This study was a part of a project registered in the Chinese Clinical Trial Registry(no.ChiCTR2100047071).Results:Among the participants,33.3%(133/400)of them experienced moderate to high diabetes distress.The content validity indices of the C-DDS17 equaled 1.00.The scale yielded a four-factor structure.The average variances extracted were 0.42e0.57,which was lower than squared correla-tions.Cronbach’s a coefficient was 0.88 for the overall scale and ranged from 0.76 to 0.81 for sub-scales.Corrected item-total correlation coefficients ranged from 0.42 to 0.61.The eighth item(“Feeling that I am often failing with my diabetes routine”)was better fit to physician distress than regimen distress but had little influence on the validation results.Conclusions:The C-DDS17 is a reliable and valid instrument for assessing diabetes distress in patients with type 2 diabetes.It is a promising instrument for early identification and management of diabetes distress in clinical practice and trials.
