SummaryThis paper describes the development and the validation of a questionnaire assessing the opinions of the relatives of patients with schizophrenia on the causes and the social consequences of the disorder. The final version of the questionnaire includes 28 items, grouped in four sub-scales (social restrictions, social distance, utility of treatments, biopsychosocial causes of schizophrenia), whose intra-rater reliability ranges from 0.36 to 0.84. Cronbach's alpha coefficient, which tests the content validity of the sub-scales, ranges from 0.56 to 0.66. Factor analysis identifies two factors (opinions on social consequences and the utility of treatments, and the beliefs on the causes of schizophrenia), which account for the 73% of the total variance. This questionnaire may be particularly useful to assess relatives'beliefs about schizophrenia and to target psychosocial interventions in the families of patients with schizophrenia.

Abstract Background: Health education basing on patients’ information-seeking style can improve the effect of health education and patients’ health outcomes. The Miller Behavioral Style Scale(C-MBSS) is widely used, but the Chinese version is lacking. The study aim was to test the reliability and validity of C-MBSS.Methods: The forward-back-translation procedure was adopted in the translation of the MBSS. Content validity was assessed in a panel of experts. In a sample of 1343 individuals including patients, patients’ caregivers, university students, and medical staff, reliability and construct validity were assessed using Cronbach’s alpha coefficient and factor analysis.Results: The C-MBSS achieved conceptual and semantic equivalence with the original scale. The item-level content validity index (I-CVI) of each item ranged from 0.78 to 1, and the averaging scale-level content validity index (S-CVI/ Ave) was 0.95. Thecronbach`s alpha coefficient for the scale and sub-scales were over 0.6. The exploratory factor analysis resulted in 2-factor assumption for each hypothetical threat-evoking scenario. Confirmatory factor analysis demonstrated a good fit between theoretical model and data, which provided confirmatory evidence for the second-order factor structure of 2-factor solution (Monitoring and Blunting).Conclusions: This study verified the reliability and validity of the C-MBSS and indicated that the C-MBSS can be used to identify individual`s information-seeking style in Chinese population.

Loneliness is usually a chronic condition which may lead to physical and psychological undesirable consequences, and requires measurement and intervention. This study was conducted with the aim of preparing a Persian version of the 11-item de Jong Gierveld Loneliness Scale and evaluating its psychometric properties among the Iranian older adults. After applying the translation-back translation method, the prepared script was subjected to the face and content validity evaluations and a Persian version of the scale was prepared. Factor analysis, concurrent validity, internal consistency, and test-retest methods were used to validate the scale. The Persian version of the 11-item de Jong Gierveld Loneliness Scale showed acceptable content validity. The negative and significant correlations between the loneliness scores and the Philadelphia Geriatric Center Morale Scale indicated that the questionnaire had acceptable concurrent validity. The results of confirmatory factor analysis confirmed two factors for the scale. Also, the results of the intra-class correlation coefficient and Cronbach’s alpha coefficient demonstrated that the scale had acceptable reliability. The Persian version of the 11-item de Jong Gierveld Loneliness Scale is an appropriate tool for measuring loneliness in the Iranian older adults.

Abstract Background Advances in technology and the expansion of nursing roles have led to complex ethical issues in nursing. Nursing students are the future clinical nursing workers and practitioners. The ethical sensitivity of nursing students is very important to the professional development of nursing students, which can strengthen the ethical cognition of nursing students, improve the ethical decision-making ability of nursing students, and is beneficial to the development of nursing students in the process of clinical practice and nursing education. However, there are no instruments to evaluate the ethical sensitivity of nursing students in China. Therefore, the purpose of this study is to evaluate the validity and reliability of the Chinese version of the Ethical Sensitivity Questionnaire for Nursing Students (ESQ-NS). Methods After obtaining the authorization of the author of the original scale, the study used the Brislin back-translation method for translation. An exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA) were performed to examine the underlying factor structure of the translated questionnaire. The Cronbach alpha coefficient, the test-retest reliability, and the corrected item-total correlation were calculated to verify the internal consistency of the scale. Results The Chinese version of ESQ-NS retained 13 items. Exploratory factor analysis (EFA) extracts four common factors, and the cumulative variance contribution rate is 62.479%. The CFA reached the adaptive standard, and the discriminant validity of the scale was good. The Cronbach alpha coefficient of this scale was 0.821, and 4 dimensions were between 0.708 and 0.738. The results of the test-retest showed that Pearson’s correlation coefficient of the overall ESQ-NS was 0.814. Corrected item-total correlation ranged from 0.337 to 0.542. Conclusions The Chinese version of the ESQ-NS has good reliability and validity, which can be used to evaluate the level of ethical sensitivity of nursing students in China.

Infollution management is a substantial dilemma in this century. There is lacking empirical evidence about infollution management. Perceived infollution has been explored based on information quality. This study aims to identify the factors of perceived infollution (information pollution) and validate those factors using confirmatory factor analysis (CFA). Researchers have personally collected data from employees of the banking sector. Factor analysis was performed to explore the factors using Statistical Package for the Social Science, and CFA was conducted to check the reliability, validity, and the model fitness in SmartPLS. The scale developed in this study has exhibited high values of reliability and validity and ensured the presence of both discriminant validity and convergent validity. The newly developed scale of perceived infollution provides a basis for most of the academicians and researchers to empirically investigate the relationship of perceived infollution with individual’s performance and organizational effectiveness, which is considered an important area of interest among the academic researchers in recent years. Extent literature review suggests that it is the first study conducted to develop measurement scale of perceived infollution (information pollution).

A new scale for the evaluation of feelings of guilt is described. Two types of guilt feeling were of potential interest: ‘delusional’ guilt or shame (experienced in relation to one's actions), and ‘affective’ guilt (a more general feeling of unworthiness). Reliability and validity analyses for the first (15–item) version of the scale were performed in three separate and contrasting clinical samples. The second and final (seven-item) version was tested in another sample of major depressives and in normal controls. The HRSD was used as a measure of severity throughout. The BDI and Widlöcher psychomotor retardation scale were also used as external criteria for the seven-item scale. Exploratory factor analysis of this sample yielded two factors – ‘cognitive/attitudinal’ and ‘mood/feeling’ – of which only the first correlated with scores for psychomotor retardation. It is suggested that these two factors represent two forms of guilt, but that only the former is related to a putative dopaminergic disorder. Guilt scores and measures of severity were not correlated. It is suggested that feelings of guilt should be considered as a behavioural marker for a subtype of depression.

This study presents the development and testing of the Overeating Tension Scale. Overeating tension was defined operationally as the total discrepancy score resulting from differences between subjects’ ratings of actual and desired feelings before overeating. The 32-item Overeating Tension Scale, derived from Apter’ s Reversal Theory, measures reported overall tension and motivation-specific tension. The scale initially included 48 items, six items for each of eight motivational states. After two instrument development studies (N = 373, N = 208), items were refined and reduced to a total of 32, or four for each of eight motivational states. The final version of the instrument was tested in two additional studies (N = 330, N = 130) that provided evidence to support the internal consistency reliability of the Overeating Tension Scale. There was support for construct validity using contrasted groups (overweight and normal weight subjects), convergent validity, and factor analysis.

Objective: To analyze the reliability and validity of a scale used to measure social support for physical activity in adolescents - ASAFA Scale. Methods: This study included 2,755 adolescents (57.6% girls, 16.5 ± 1.2 years of age), from Joao Pessoa, Paraiba, Brazil. Initially, the scale was consisted of 12 items (6 for social support from parents and 6 from friends). The reliability of the scale was estimated by Cronbach's alpha coefficient (α), by the Composite Reliability (CR), and by the model with two factors and factorial invariance by Confirmatory Factor Analysis (CFA) adequacy. Results: The CFA results confirmed that the social support scale contained two factors (factor 1: social support from parents; factor 2: social support from friends) with five items each (one item was excluded from each scale), all with high factor loadings (> 0.65) and acceptable adjustment indexes (RMR = 0.050; RMSEA = 0.063; 90%CI: 0.060 - 0.067); AGFI = 0.903; GFI = 0.940; CFI = 0.934, NNFI = 0.932). The internal consistency was satisfactory (parents: α ≥ 0.77 and CR ≥ 0.83; friends: α ≥ 0.87 and CR ≥ 0.91). The scale's factorial invariance was confirmed (p > 0.05; Δχ2 and ΔCFI ≤ 0.01) across all subgroups analyzed (gender, age, economic class). The construct validity was evidenced by the significant association (p < 0.05) between the adolescents physical activity level and the social support score of parents (rho = 0.29) and friends (rho = 0.39). Conclusions: The scale showed reliability, factorial invariance and satisfactory validity, so it can be used in studies with adolescents.

PurposeSince reflectivity has a crucial role in education, it has attracted researchers’ attention in the last decades. As such, the present study aimed to construct and validate a questionnaire to assess the barriers to reflective practices of Iranian ESP (English for Specific Purposes) instructors. Furthermore, this study aimed to investigate the reliability of the scale.Design/methodology/approachTo attain the purpose of the study, the researchers developed the first item pool of the questionnaire which included 67 items. Then, 4 experts were asked to pass their judgments on the items. Accordingly, 37 items were excluded and the next draft of the questionnaire that included 30 items remained. After their feedback, the revised scale was piloted with 10 ESP instructors to check the clarity of items. Then, the scale was administered to 210 ESP instructors. At the next stage, an exploratory factor analysis (EFA) was run to assess the construct validity of the questionnaire. Based on the results, three items were removed. To investigate the internal consistency of the scale, a Cronbach’s alpha coefficient was employed.FindingsThe final version of the scale included 27 items with three subscales, namely, learners, instructors and institutions’ issues. The results revealed that the questionnaire enjoyed an acceptable level of validity and reliability.Originality/valueApart from a few studies, no other study has scrutinized barriers to EFL teachers’ reflectivity. In addition, in the realm of ESP, no study has developed a scale to measure barriers to ESP teachers’ reflective practice.

Abstract Objective: In this study, we aimed to evaluate the validity and reliability of the free oral pre-exposure prophylaxis (PrEP) adherence questionnaire among patients with sexually transmitted infection who do not have HIV infection in Shanghai. Methods: We conducted a cross-sectional study among 816 patients from sexually transmitted infection (STI) clinics in Shanghai. The questionnaire included self-reported demographic characteristics, items on adherence to free oral pre-exposure prophylaxis (PrEP), and PrEP uptake behavior measurement. Item analysis was carried out by calculating the critical ratio and item-total correlations. Internal consistency and split-half reliability were measured to assess reliability. Content validity, construct validity, convergent validity and discriminant validity were measured to assess validity. We conducted logistic regression with receiver operating characteristic (ROC) curve analysis to assess the predictive value of the adherence questionnaire for PrEP uptake behavior. Results: All items were considered acceptable in the item analysis (P<0.05). The questionnaire had a Cronbach’s alpha of 0.757 and split-half reliability of 0.633. The scale-level content validity index (CVI) was 0.938 and the item-level CVI of each item ranged from 0.750 to 1. In exploratory factor analysis, we introduced a four-factor model accounting for 79.838% of the aggregate variance with all factors loading more than 0.4, which was validated in confirmatory factor analysis (c2=47.1, degrees of freedom=14, root mean square error of approximation=0.078). According to regression analysis, adding PrEP adherence questionnaire scores contributed to prediction of PrEP uptake behavior (P<0.001). The maximum area under the ROC curve was 0.778 (95% confidence interval: 0.739–0.817), corresponding to a cutoff score of 9.Conclusion: The PrEP adherence questionnaire generally has acceptable reliability and validity. This questionnaire can be used as a tool to evaluate PrEP adherence in patients with STI who do not have HIV infection.

Our study examined the psychometric properties and factor structure of an instrument to assess emotional climate during the COVID-19 pandemic using a sample of 601 Portuguese individuals. Two sub-samples were created, one to perform an exploratory factor analysis (EFA), composed of 300 participants, and the other to conduct a confirmatory factor analysis (CFA), composed of 301 individuals. Two factors were found: positive and negative emotional climate. In the EFA, both factors established a negative and significant correlation. However, the CFA presented a better fit with two independent factors. Reliability analysis indicated acceptable values for both dimensions. There was also evidence of discriminant, convergent, and criterion validity. More negative emotions were perceived regarding the social climate. Results were discussed in the frame of different positive and negative psychosocial variables related to positive and negative emotional climates, as well as positive emotional climate as a resource for collective resilience.
