Construct validity and internal consistency of the Brazilian version of Leisure Attitude Measurement for the elderly

ABSTRACT Objective: To evaluate the construct validity and internal consistency of the Brazilian version of Leisure Attitude Measurement for the elderly. Method: Methodological study with a quantitative approach. The data were collected for three months through domiciliary visits to a random and representative sample of 384 elders. The internal consistency was measured through Cronbach alpha coefficient. Construct validity was evaluated through exploratory factor analysis. Factor extraction was conducted per principal components, following the Kaiser criterion, with rotation through Varimax solution. Results: The participants’ mean age was 70,9 and they were mostly women, married, living with relatives, with one to four years of education, and with an income of up to one minimum wage. The final model of the instrument has conserved three factors, under the parsimony criterion, explaining 50% of data variance, with a total of 27 items distributed across the cognitive, affective, and behavioral domains, with an overall Cronbach alpha coefficient of 0.89. Conclusion: The proposed structural model has shown construct validity and an appropriate internal consistency, explaining 50% of data variability. Its application can promote the understanding of social reality and encourage a positive attitude and elderly engagement in leisure activities.

BACKGROUND Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism. OBJECTIVE The main objective of this study was to validate the French version of the WART. METHODS Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers’ sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients). RESULTS Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI −9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity. CONCLUSIONS The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.

Aim: the purpose of this study was to translate and adapt the English version of the Vocal Fatigue Index (VFI) into the Spanish language. Methods: the English version of the Vocal Fatigue Index (VFI) was translated into Spanish by two bilingual speech-language pathologists, and then was back-translated into English. The Spanish VFI (o “Índice de Fatiga Vocal”, IFV) was administrated to a pilot group of 10 individuals, which revealed some small typographical and grammatical adjustments to the index. The final updated version was then administrated to 34 subjects (21 with voice disorders, and 13 without voice disorders). Internal consistency and scale reliability were analyzed using Cronbach alpha coefficient. Results: a high Cronbach alpha coefficient for the three factors (0.87) was obtained. The results of the item role in reliability of the Spanish VFI demonstrated that all of them showed a positive role according to this criterion. The results of the ANOVA indicate a statistically significant difference between groups on the three scores of the Spanish translation of the VFI. In comparison to the healthy participants, those with voice disorders obtained statistically significant higher scores for the Spanish VFI subscales. Conclusion: the present study suggests that the Spanish translation of the Vocal Fatigue Index has a good internal consistency and high reliability on each of the three factors. The results suggest that the Spanish VFI can be used reliably to identify persons with vocal fatigue and has good clinical validity.

Abstract Background The objective of this study was to verify the reliability, discriminatory power and construct validity of the Kidscreen-27 questionnaire in Brazilian adolescents. Methods Adolescents that participated of the pilot study (210 adolescents; 52.9% boys; 13.7 years old) and of the baseline (816 participants; 52.7% girls; 13.1 years old) of the Movimente Project in 2016/2017 composed the sample of the present study. This project was carried out in six public schools in the city of Florianópolis, Santa Catarina, Brazil. Test–retest reproducibility was assessed by the intraclass correlation coefficient and Gwet coefficient; internal consistency through McDonald's Omega; Hankins' Delta G coefficient verified the scale's discriminatory power and; confirmatory factor analysis to assess construct validity. Results Reproducibility values ranged from 0.71 to 0.78 for the dimensions (ICC), and ranged from 0.60 to 0.83 for the items (Gwet). McDonald's Ômega (0.82–0.91) for internal consistency measures. Discriminatory power ranging from 0.94 for the dimension Social Support and Friends to 0.98 for Psychological Well-Being. The factorial loads were > 0.40, except for item 19 (0.36). The fit quality indicators of the model were adequate (X2[df] = 1022.89 [311], p < 0.001; RMSEA = 0.053 (0.049–0.087); CFI = 0.988; TLI = 0.987), confirming the five-factor structure originally proposed. Conclusions The Brazilian-version Kidscreen-27 achieved good levels of reproducibility, internal consistency, discriminatory power and construct validity. Its use is adequate to measure the health-related quality of life of adolescents in the Brazilian context.

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.

The aim of this study was to develop and validate a questionnaire that measures the effectiveness of communication during organisational change interventions. A draft questionnaire was completed by a sample of convenience comprising 521 participants. The questionnaire contained 109 items in question format with a Likert-type response scale anchored at the extreme ends. The data was factor analysed and an iterative item analysis was executed. The results yielded a single scale with a Cronbach Alpha coefficient of 0,99. It is concluded, therefore, that the conceptualised domain of “communicating-for-change"? could be measured successfully through the use of the instrument developed in this study. Opsomming Die doel van hierdie studie was die ontwikkeling en validering van ‘n vraelys wat die doeltreffendheid van kommunikasie tydens organisatoriese veranderingsintervensies meet. ‘n Konsepvraelys is op ‘n geleentheidsteekproef van 521 deelnemers afgeneem. Die vraelys het bestaan uit 109 items in vraagformaat met ‘n Likert-tipe responsskaal wat by die ekstreme pole geanker is. Die data is gefaktoranaliseer en ‘n iteratiewe itemontleding is uitgevoer. Die resultate het ‘n enkele skaal met ‘n Cronbach Alfa koëffisient van 0,99 opgelewer. Daar is derhalwe aanvaar dat die gekonseptualiseerde domein van “kommunikasie-vir-verandering” suksesvol met die instrument wat in die studie ontwikkel is, gemeet kon word.
