ABSTRACT: Objective: To verify the internal construct validity of the Brazilian Portuguese version of a tool for measuring the general population’s knowledge of human papillomavirus (HPV). Materials and methods: A cross-culturally adapted Brazilian Portuguese version of a measurement tool originally designed for English speaking populations was administered to 330 adults in Tubarão, Santa Catarina, Southern Brazil. After examining the overall suitability of the method, we performed investigations based on the item response theory and exploratory factor analysis. Results: Ten of the 29 items presented a low contribution to the construct and were excluded from subsequent analysis. The factor analysis yielded three factors, which explained approximately 51% of the variance variability. A different arrangement from the original measurement tool was found: general HPV knowledge, with six items; HPV vaccination knowledge, with five items; HPV transmission and testing knowledge, with eight items. Conclusion: The Brazilian Portuguese version under study presented a different behavior from the original measurement tool, but proved to be a reliable and valid instrument in assessing the Brazilian population’s knowledge about HPV.

CONTEXT AND OBJECTIVE: Rheumatoid arthritis is a chronic systemic disease that causes joint damage. A variety of methods have been used to evaluate the general health status of these patients but few have specifically evaluated the hands. The objective of this study was to translate, perform cultural adaptation and assess the validity of the Michigan Hand Outcomes Questionnaire for Brazil.DESIGN AND SETTING: Validation study conducted at a university hospital in Curitiba, Brazil.METHODS: Firstly, the questionnaire was translated into Brazilian Portuguese and back-translated into English. The Portuguese version was tested on 30 patients with rheumatoid arthritis and proved to be understandable and culturally adapted. After that, 30 patients with rheumatoid arthritis were evaluated three times. On the first occasion, two evaluators applied the questionnaire to check inter-rater reproducibility. After 15 days, one of the evaluators reassessed the patients to verify intra rater reproducibility. To check the construct validity at the first assessment, one of the evaluators also applied other similar instruments.RESULTS: There were strong inter and intra rater correlations in all the domains of the Michigan Hand Outcomes Questionnaire. Cronbach's alpha was higher than 0.90 for all the domains of the questionnaire, thus indicating excellent internal validity. Almost all domains of the questionnaire presented moderate or strong correlation with other instruments, thereby showing good construct validity.CONCLUSION: The Brazilian Portuguese version of the Michigan Hand Outcomes Questionnaire was translated and culturally adapted successfully, and it showed excellent internal consistency, reproducibility and construct validity.

This methodological study aimed to evaluate the construct validity and reliability of the Brazilian-Portuguese version of Antonovsky's Sense of Coherence Questionnaire (ASCQ) among nursing professionals. The study included 211 professionals who worked in the surgical wards of eleven hospitals in a city in the interior of the State of Paraná-Brazil. The majority of participants were female (86.7%), with a mean length of service of 9.3 (SD=8.0) years. Construct validity was evaluated using Pearson correlation tests between the measures of sense of coherence and correlated constructs, obtaining strong negative correlations between sense of coherence and anxiety (r=-0.53) and sense of coherence and depression (r=-0.61). Internal reliability, assessed by Cronbach's alpha, obtained an acceptable value of 0.87. The Brazilian-Portuguese version of ASCQ maintained the psychometric properties of the original scale when used with nursing professionals.

OBJECTIVE: Impulsivity is associated with different psychiatric disorders. The Barratt Impulsiveness Scale version 11 is one of the scales mostly used to measure impulsivity and it does not have a validated version for Brazilian Portuguese. The objective of this study is to adapt and conduct the construct validation of the Barratt Impulsiveness Scale version 11 for adolescents. METHOD: The scale was translated and adapted into Portuguese and then back-translated into English. The psychometric proprieties, factor analysis and construct validity were evaluated in two samples: 18 bilingual undergraduate medical students and 464 male adolescents between 15 and 20 years old from a well-delimited geographical area in the city of Canoas, southern Brazil. RESULTS: The adolescent sample had a mean age of 17.3 ± 1.7 years. Intra-class correlation coefficient achieved a value of 0.90, and internal consistency had alpha of 0.62. Factor analysis did not identify the 3 factors of the original scale. Impulsivity scores from the Barratt Impulsiveness Scale version 11 had a correlation with scores for attention deficit/hyperactive disorder and oppositional defiant disorder and with number of symptoms of conduct disorder, suggesting an appropriate construct validity of the scale. CONCLUSION: Even considering some limitations in the Portuguese version, Barratt Impulsiveness Scale version 11 can be used in male adolescents and should be tested in other populations.

Objective: The aim of this study is to make the Turkish validity and reliability of the vaccine hesitation scale to be used in combating experienced or possible pandemics in the future. Methods: It is a methodological study in which the Turkish validity and reliability of the "Vaccine Hesitancy Scale" developed by Larson et al. (2015) was modified for pandemics. Explanatory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted with the data collected from 617 volunteers for construct validity. Cronbach's Alpha Coefficient and language and construct validity were performed for reliability and validity. Results: As a result of EFA and CFA, the 10-item "Vaccine Hesitancy Scale in Pandemics" showed a two-factor structure. The two-factor structure explains 68.53% of the total variance. Factor loadings related to the items of the scale vary between 0.638 and 0.887. Confirmation of EFA results with CFA results was found to provide construct validity. It was observed that the reliability criterion was met by determining the Cronbach Alpha Coefficient as 0.901. Conclusion: It is thought that the "Vaccine Hesitancy Scale in Pandemics", which has been conducted with the data obtained from people with different socio-demographic characteristics of the Turkish people, can be a reference that can be used by researchers as a valid and reliable measurement tool.

96 Background: The Female Self-Advocacy in Cancer Survivorship (FSACS) Scale is a new measurement tool designed to address the increasing need for cancer survivors to lead their care in face of barriers. Based on previous input from female cancer survivors and other stakeholders, the purpose of this study is to evaluate the construct validity of the FSACS Scale. Construct validity is supported by evidence from: (I) Internal structure consistent with the underlying model of self-advocacy; (II) Sensitivity to differences between known groups; (III) Relationships between self-advocacy and key predictors (openness and conscientiousness; information engagement; social support) and outcomes (symptom distress and healthcare utilization); (IV) Relationships between self-advocacy and related concepts (patient activation; self-advocacy within the HIV/AIDS population); and (V) Relationships between self-advocacy and criterion measures. Methods: A mixed-mode cross-sectional survey design was used. Women with a history of an adult diagnosis of invasive cancer were recruited from two patient registries and seven advocacy organizations. Analyses included an exploratory factor analysis, t-tests, and bivariate correlations. Results: 315 adult female cancer survivors completed the survey. Evidence from all five construct validity hypotheses supports the construct validity of the FSACS Scale. The factor analysis confirmed the three underlying dimensions of self-advocacy resulting in a 20-item measure explaining 45.87% of the variance in responses with subscales’ Cronbach’s alphas between 0.791 and 0.850. Conclusions: Results support that the FSACS Scale is a theoretically-grounded measure of self-advocacy that can be used by clinicians and researchers to identify women at-risk for poor outcomes associated with low self-advocacy.

Background and Purpose: The aim of the study was to analyze the factor structure and the reliability of the Brazilian-Portuguese version of the Burn Specific Health Scale—Revised (BSHS-R) in a sample of Brazilian burned adults. Methods: This study was a cross-sectional study. The internal consistency was analyzed using Cronbach’s α, considering coefficients ≥.70 as appropriate. We conducted confirmatory factor analysis (CFA) to test the hypothesis that the BSHS-R Brazilian-Portuguese version has a factor structure similar to the original. We assessed the factor structure of the BSHS-R Brazilian-Portuguese version by CFA, examining three models: three-factor, six-factor, and seven-factor structure. Results: The participants were 299 burned adults. The CFA indicated good model fit indices for the seven-factor model (root mean square error of approximation = .062; goodness-of-fit index = .844; adjusted goodness-of-fit index = .809; Akaike information criterion = 1,054.06). The seven-factor BSHS-R Brazilian-Portuguese version showed Cronbach’s α of .93. Conclusions: The BSHS-R Brazilian-Portuguese version with seven factors is reliable and valid and measures the perceived health status construct.

ABSTRACT BACKGROUND: Fatigue is a common symptom in patients with inflammatory bowel diseases (IBD). A translated and culturally adapted, instrument with robust psychometric for measuring fatigue in Brazilian patients with IBD is needed. OBJECTIVE: To translate and cross-culturally adapt the inflammatory Bowel Disease Fatigue Scale (IBD-F) into Brazilian-Portuguese and to test its measurement properties in Brazilian patients with IBD. METHODS: Data from 123 patients with IBD were collected. In addition to IBD-F, the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) was used. The measurement properties tested were: internal consistency, reproducibility (reliability and agreement), construct validity, internal and external responsiveness, and ceiling and floor effects. RESULTS: The Brazilian-Portuguese version of the IBD-F showed excellent internal consistency (Cronbach’s alpha of 0.95), excellent reproducibility (ICC=0.97) and a minimal detectable change of 6.0 points. The construct validity was demonstrated with a good correlation between the IBD-F and FACIT-F (r=- 0.46). Effect sizes used for measuring internal responsiveness were moderate among those with Crohn’s (0.66) disease and low in patients with ulcerative colitis (0.24). The Brazilian-Portuguese version of the IBD-F presented with high external responsiveness for Crohn’s disease (0.84) and with low external responsiveness for ulcerative colitis (0.33). The area under the curve considered for responsiveness was 0.84. Twenty-five percent of floor effects and no ceiling effect were recorded. CONCLUSION: The Brazilian-Portuguese version of IBD-F has adequate measurement properties and its use can be recommended in clinical practice and research.
