ABSTRACT
The Healthy China construction initiative highlights the concept of patient-centered value-based health care,and the value appeal of doctors'medical service is also increasing.This study attempts to introduce the concept of public service motivation in general public organizations into professional public healthcare organizations——public hospitals,and proposes the concept of"value-based medical service motivation"as an expression of public service motivation for doctors in public hospitals.Through qualitative analysis and quantitative measurement,this paper constructs the concept of"public hospital doctors'value-based medical service motivation",finds its conceptual structure,namely responsibility commitment,professional adherence,reputation maintenance,and norm compliance,and finally forms a value-based medical service motivation scale.This paper confirms that doctors in public hospitals in China have multi-dimensional value-based medical service motivation,present different motivational expressions or behavioral tendencies,and constantly deal with and balance the public value tensions in the practice of realizing the patient-centered value-based medical goal.This scale provides an effective tool for measuring doctors'value-based service motivation,and provides theoretical and practical support for further investigating the influencing factors of doctors'motivation for value-based medical services,improving the medical service capacity of public hospitals,adjusting medical behavior,and advancing doctor-patient trust.
ABSTRACT
Objective:To develop the Suicide Outcomes Scale for Undergraduates with Suicidal Ideation(SO-SUSI)and test its validity and reliability.Methods:Based on semi-structured interview,literature review and expert discussion,main aspects and indicator system were defined.The initial version of SOSUSI was formed,and items were either modified from existing scales targeting the relevant constructs,or compiled according to previous inter-view results.A total of 607 undergraduates with suicidal ideation were enrolled.The sample was randomly divided in half,one half(n=317)was used for item analysis and exploratory factor analysis,and another half(n=290)for confirmatory factor analysis.All data were used for reliability analysis.The Self-rating Depression Scale(SDS)and Suicidal Intent(SI)were used for criterion validity.Results:The SOSUSI included 39 items in 4 dimensions(nega-tive reinforcement of suicide,negative consequences of suicide,loss of suicide,and positive reinforcement of sui-cide)which explained 50.10%of the total variance.Confirmatory factor analysis showed that the four-factor struc-ture model fitted well(x2/df=3.27,CFI=0.92,TLI=0.91,IFI=0.92,SRMR=0.09).The scores of negative re-inforcement and positive reinforcement of suicide were positively correlated with the SDS and SI scores(ICC=0.15-0.33,Ps<0.05),while the scores of negative consequences and loss of suicide were negatively correlated with the SI scores(ICC=-0.42--0.56,Ps<0.05).The Cronbach's α coefficients of each dimension ranged from 0.79 to 0.91.Conclusion:The Suicide Outcomes Scale for Undergraduates with Suicidal Ideation(SOSUSI)has good validity and internal consistency reliability.
ABSTRACT
Abstract Background Skepticism has traditionally been associated with critical thinking. However, philosophy has proposed a particular type of skepticism, termed naive skepticism, which may increase susceptibility to misinformation, especially when contrasting information from official sources. While some scales propose to measure skepticism, they are scarce and only measure specific topics; thus, new instruments are needed to assess this construct. Objective This study aimed to develop a scale to measure naive skepticism in the adult population. Method The study involved 446 individuals from the adult population. Subjects were randomly selected for either the pilot study (phase 2; n = 126) or the validity-testing study (phase 3; n = 320). Parallel analyses and exploratory structural equation modelling were conducted to assess the internal structure of the test. Scale reliability was estimated using Cronbach's alpha and McDonald's omega coefficients Finally, a multigroup confirmatory factor analysis was performed to assess invariance, and a Set- Exploratory Structural Equation Modeling was applied to estimate evidence of validity based on associations with other variables. Results The naive skepticism scale provided adequate levels of reliability (ω > 0.8), evidence of validity based on the internal structure of the test (CFI = 0.966; TLI = 0.951; RMSEA = 0.079), gender invariance, and a moderate inverse effect on attitudes towards COVID-19 vaccines. Conclusions The newly developed naive skepticism scale showed acceptable psychometric properties in an adult population, thus enabling the assessment of naive skepticism in similar demographics. This paper discusses the implications for the theoretical construct and possible limitations of the scale.
ABSTRACT
Purpose: The purpose of this study was to develop a scale that can measure the concerns of cancer patients undergoing outpatient radiation therapy. Method: First, items were created based on a review of the literature, and a draft scale was created by examining content validity using the Item-level Content Validity Index (I-CVI). In the main study, researcher conducted an anonymous, self-administered questionnaire survey on 400 cancer patients undergoing outpatient radiation therapy at five institutions, and examined the reliability and validity of the scale. Result: Exploratory factor analysis identified nine items with two factors (concern about living with cancer and concern about living with irradiation). The Cronbach's alpha coefficient for the entire scale was 0.848. The goodness of fit in confirmatory factor analysis showed GFI=0.930, AGFI=0.879, CFI=0.926 and SRMR=0.058. No correlation was observed with STAI Y-1, and a certain level of discriminant validity was confirmed. Conclusion: We generally confirmed the reliability and validity results of a concern scale for cancer patients receiving outpatient radiotherapy.
ABSTRACT
Background@#The medical curriculum is one of the most stressful academic curricula worldwide. Studies indicate that great levels of stress, that encompass academics to personal life, may be connected to a number of worrying statistics for the mental health of Philippine medical students.@*Objectives@#To develop a validated stressor-coping style scale for students in a public medical school.@*Methods@#The study employed a sequential mixed-methods design. An open-ended questionnaire was used to determine the common stressors and coping styles through convenience sampling. A scale was constructed from this data and was statistically tested for concurrent validity and reliability from a random sample.@*Results@#Following thematic analysis, an initial six stressor domains and eleven coping mechanisms were identified. However, after item analysis and principal component analysis of responses, the scale was transformed to seven stressor domains and five coping mechanism domains. All of which are deemed internally consistent (α>0.6). Scores from the scale were also convergent with the scores of Brief COPE (r=0.5 to 0.9). @*Conclusions@#The developed stressor-coping style scale for medical students is a reliable and valid tool for Filipino medical students in a public medical school.

Menstruation is a physiological process experienced by adolescent girls and women. Menstruation and premenstrual symptoms affect the Quality of Life. Different scales are available to measure QOL for different gynaecological problems but none scale available to measure QOL during Menstruation. WHO defines Quality of Life as an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns. It is a multidimensional concept that includes domains related to physical, mental, emotional and social functioning. It goes beyond direct measure of population health, life expectancy and causes of death and focuses on the impact health status on quality of life. To develop a comprehensive instrument to assess the health-related QOL among the women during menstruation. The creation of a scale to assess QOL during the menstrual cycle is indeed a significant endeavour. Menstrual Health Outcomes Questionnaire contains 35 questions from different domains. After getting ethical approval pilot and pivotal study conducted. Adolescents were randomly recruited in the study. Data was captured and entered in SPSS version 20. Principle factor analysis was determined to find construct validity among independent and dependent variables. Man-Whitney U test was determined. Questionnaire has Cronbach’s alpha 0.796, determined 35 questions. Intraclass corelation coefficient was found 0.786. KMO and Bartlett’s test was found 0.820 with high significance. (p=0.000) Menstrual Health Outcome Questionnaire has been established as a valid and reliable tool for assessing the QOL among women during menstruation.
ABSTRACT
Purpose: The purpose of this study is to develop a “Multidisciplinary Collaboration Ability Scale (MCAS)” and examine the reliability and validity for medical professionals engaged in cancer care. Method: The first MCAS draft was created, and the content validity and surface validity of the scale were examined for medical professionals. Next, a cross-sectional questionnaire survey was conducted on medical professionals engaged in cancer care who worked in medical institutions. Exploratory factor analysis and known-groups technique were carried out, coefficient α calculated, and concurrent validity examined. This study was conducted with the approval of the research ethics review. Result: Exploratory factor analysis resulted in 33 items of 4 factors (ability to promote discussion, foundational relationship building, self-control, and problem-solving activities). The MCAS score was significantly higher for those who had participated in a multidisciplinary workshop and those who had more years of experience. Coefficient α for the entire scale and for each factor was .80 and above. Examination of concurrent validity showed a moderate correlation. Conclusion: The reliability and validity of MCAS in its development stage were generally verified.

ABSTRACT
Abstract With the outbreak of the COVID-19 pandemic, artificial intelligence (AI) has been widely used in fields such as medical treatment, while the threat of artificial intelligence has also received extensive attention. However, this topic has been only limitedly explored in China. To provide a measurement tool for AI threat research in China, this study aimed to examine the validity and reliability of the Threats of Artificial Intelligence Scale (TAI) in two Chinese samples of adults (N1 = 654, N2 = 1483). Results of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) suggested that the one-factor model of TAI as the best fitting model. Furthermore, the Chinese TAI was significantly related to Positive and Negative Affect Scale and Self-Rating Anxiety Scale, proving good criterion-related validity of the Chinese TAI. In sum, this study suggested the Chinese version of the TAI as a reliable and effective tool in assessing AI threat in the Chinese context. Limitations and future directions are discussed.

ABSTRACT
Resumo O objetivo é apresentar uma proposta de mensuração do nível de urbanicidade das cidades brasileiras com dados do censo 2010. Estudo ecológico que usou a classificação oficial do Instituto Brasileiro de Geografia e Estatística (IBGE) - urbano rural - e a de Veiga (2002) - Pequeno, Médio e Grande porte. Utilizou-se árvore de classificação para predição com Validação Cruzada. Testaram-se dois modelos de análise. No modelo 1, as variáveis independentes foram as características físicas e sociais das cidades, e o desfecho a classificação no critério IBGE. No modelo 2, além das variáveis usadas no modelo 1, incluiu-se como covariável o critério de Veiga (2002). Construída a árvore, calcularam-se a sensibilidade, especificidade e acurácia. O modelo 2 apresentou ganhos estatisticamente significante na predição do nível de urbanicidade, aumentando as estimativas de sensibilidade e acurácia nos conjuntos usados para teste. Municípios de grande porte foram classificados automaticamente como urbano no modelo 2. Mas, para predizer a urbanicidade das demais cidades houve a combinação dos critérios de Veiga (2002) com outras características físicas e sociais das cidades. A combinação de indicadores no modelo 2 permitiu definir critérios quantitativos para criar tipologias de classificação do urbano rural para o territorial municipal brasileiro.
Abstract The scope of this study is to present a proposal for measuring the level of urbanicity in Brazilian cities based on data from the 2010 census. It is an ecological study, which used the official (urban rural) classification of IBGE (Instituto Brasileiro de Geografia e Estatística, in portuguese) and that of small, medium and large cities of Veiga (2002). A classification tree was used for prediction with Cross Validation. Two models of analysis were tested. In model 1, the independent variables were the physical and social characteristics of the cities, and the outcome was classification in accordance with IBGE criteria. In model 2, in addition to the variables used in model 1, the Veiga (2002) criterion was included as a covariate. Sensitivity, specificity and accuracy were then calculated. Model 2 showed statistically significant gains in the prediction of the level of urbanicity, increasing the sensitivity and accuracy estimates in the sets used for testing. Large cities were automatically classified as urban in model 2. However, to predict the urbanicity of other cities, Veiga (2002) criteria were combined with other physical and social characteristics of cities. The combination of indicators in model 2 enabled the definition of quantitative criteria to create typologies for classifying the urban rural definition in the Brazilian municipal territory.

Background & objectives: COVID-19 pandemic has triggered social stigma towards individuals affected and their families. This study describes the process undertaken for the development and validation of scales to assess stigmatizing attitudes and experiences among COVID-19 and non-COVID-19 participants from the community. Methods: COVID-19 Stigma Scale and Community COVID-19 Stigma Scale constituting 13 and six items, respectively, were developed based on review of literature and news reports, expert committee evaluation and participants’ interviews through telephone for a multicentric study in India. For content validity, 61 (30 COVID-19-recovered and 31 non-COVID-19 participants from the community) were recruited. Test–retest reliability of the scales was assessed among 99 participants (41 COVID-19 recovered and 58 non-COVID-19). Participants were administered the scale at two-time points after a gap of 7-12 days. Cronbach’s alpha, overall percentage agreement and kappa statistics were used to assess internal consistency and test–retest reliability. Results: Items in the scales were relevant and comprehensible. Both the scales had Cronbach’s ? above 0.6 indicating moderate-to-good internal consistency. Test–retest reliability assessed using kappa statistics indicated that for the COVID-19 Stigma Scale, seven items had a moderate agreement (0.4-0.6). For the Community COVID-19 Stigma Scale, four items had a moderate agreement. Interpretation & conclusions: Validity and reliability of the two stigma scales indicated that the scales were comprehensible and had moderate internal consistency. These scales could be used to assess COVID-19 stigma and help in the development of appropriate stigma reduction interventions for COVID-19 infected, and mitigation of stigmatizing attitudes in the community.
ABSTRACT
Background: Vitiligo places a significant psycho-social burden on caregivers and family members. Aims: The aim of the study was to develop and preliminarily validate a scale to measure the psychosocial impact of vitiligo on adult family members. Methods: Themes that emerged from qualitative interviews and a focus group discussion with family members were used to generate items for a preliminary scale, followed by pre-testing and scale development. The new scale was then tested with two comparator scales and a global question. Results: A preliminary scale with 32 items was pilot tested on 30 participants. Following this, the scale was condensed to 16 items in 12 domains that were administered to 159 participants. Scale scores ranged from 0 to 48 with a mean of 19.75 ± 12.41. The scale had excellent internal consistency with Cronbach’s alpha coefficient of 0.92 (0.70–0.95) and also showed good test-retest reliability at two weeks (r = 0.946). The scale showed criterion, convergent and known group validity. Limitations: It was conducted in a large teaching hospital which may have resulted in selection of patients with persistent or progressive disease and more worried family members. Vitiligo is highly stigmatized in our country and the performance of the scale may need to be evaluated in other communities and cultures as well where stigma is less oppressive. Conclusion: Family Vitiligo Impact Scale appears to be an easy-to-complete, reliable and valid instrument to measure the psychosocial impact of vitiligo in family members of patients. It may be useful as an outcome measure in both clinical and research settin

An item pool was established and optimized with case review, patient interview, expert questionnaire survey and consensus conference. The PRO scale was established finally. Results:A pool of post-stroke aphasia items based on the holistic view of TCM was constructed in the physical, psychological and social model. The Expert Comment Form for the PRO Scale for Aphasia after Stroke was formed after sorting out the item pool. After expert surveys and meeting discussion, 40 items were finally selected to form the first version of Patient-reported Outcomes Scale for Post-stroke Aphasia-TCM. Conclusion:The first version of Patient-reported Outcomes Scale for Post-stroke Aphasia-TCM has been developed based on the TCM holism and the concept of PRO, which can be evaluated clinically.
ABSTRACT
Objective: Sustained practice of Yoga leads to self-awareness, physical strength and high sense of energy. Yoga stimulates antioxidant levels in the body and reduces likelihood of dental disorders. No research has been undertaken connecting perception on yoga and oral health behaviors. The present study is an attempt to develop a psychometric scale entitled Perceived Benefits on Yoga Scale (PBYS) to measure individuals' perception on Yoga in relation to oral health behaviors. Material and methods: The psychometric tool was developed based on the concepts of Health Benefit Model (HBM). Among the four components of the model, the present study considered "perceived benefits" component. A total of 206 individuals participated in the study. To analyze the scale theoretically, face and content validity were assessed. Reliability of the scale was tested using Cronbach's alpha and Spearman-Brown coefficient. Using exploratory and confirmatory factor analysis, construct validity was tested. Cronbach alpha and Spearman- Brown coefficient were applied to test the reliability of scale. Results: There were six items in the final scale, with a Spearman- Brown coefficient of 0.92 and Cronbach's alpha of 0.91. Statistically significant (p < 0.001) positive correlation was found between POBYS scores and Yoga Self-Efficacy Scale (YSES). Validity of scale is within accepted range as indicated by Goodness of Fit indices. Conclusion: POBYS is a reliable and valid measure of perception on yoga outcomes with specific reference to oral health behavior. (AU)

BACKGROUND/AIMS: The aim of this study was to develop ‘Koreans Gut Quotient Measurement Scales (GQ)’, in which Koreans respond to questionnaires about the subjective feelings and symptoms of their intestinal health status.METHODS: Among 66 items pooled from previous studies and 4 items that were added following a focus group interview, 15 items were chosen using the Delphi survey. The content validity was evaluated using the content validity ratio. Data collected from 1,120 people from the general public in Korea were analyzed to verify the reliability and validity of GQ.RESULTS: The finalized GQ consisted of 17 items (including two exploratory measurement items) that were classified into three independent factors based on exploratory factor analysis (EFA): ‘perceived intestine discomfort’, ‘bowel movement discomfort’, and ‘bowel movement control discomfort’. The discriminant and convergent validity of GQ were identified using EFA, reliability test, and confirmatory factor analysis. In addition, the criterion-related validity of GQ was identified using correlation and multiple regression analysis.CONCLUSIONS: The GQ, which is a simplified intestinal health index developed based on an easy questionnaire for the public to understand, can be used as a tool for the public to evaluate their own intestinal health and determine when to visit clinics.
