Project description:Background Assessment tools are commonly used in different fields of health to assist in the diagnosis, the evaluation of the response to treatment, the measurement of quality of life and the establishment of the prognosis. Objectives Translate, culturally adapt and perform the psychometric validation of the Somatic Symptom Scale (SSS-8) for use in the Brazilian population. Methods Cross-cultural adaptation followed a combination of guidelines and for psychometric evaluation a sample of 300 patients was recruited. All recommended measurement properties by the Consensus-based Standards for the selection of health status Measurement Instruments were evaluated, including analysis by an expert committee and analysis by the target public. The Skindex-16 was used for the evaluation of convergent validity and Cronbach’s alpha was used for the determination of the internal consistency of the translated version of the SSS-8. Results The final version received approval from five experts and the agreement index was 100% for all items. During the pretest, the scale was administered to 300 patients with psoriasis and none of the items needed to be altered. A moderate correlation was found between the Skindex-16 and SSS-8-BRA. In the analysis of internal consistency, Cronbach’s alpha for the SSS-8-BRA was 0.81. Conclusion The SSS-8 is a valid and reliable tool for the assessment of somatic symptoms in the Brazilian population. Supplementary Information The online version contains supplementary material available at 10.1186/s12875-022-01836-2.

Project description:Objectives: The implementation of obstetric hybrid simulation and interprofessional collaboration between midwives and anesthetists in labor emergencies fostered the need to evaluate the impact of such a program. The original Interprofessional Attitude Scale (IPAS) assesses interprofessional attitudes among health professional students and includes the 2011 and 2016 Interprofessional Collaborative Practice report competency domains. The purpose of this study was to create a German version of the IPAS (G-IPAS) to use for the education of healthcare students. Methods: We performed the translation and validation of the IPAS in five steps: translation to German according to the International Society of Pharmaeconomics and Outcome Research guidelines; nine cognitive interviews with healthcare professionals and students;calculation of the Content Validity Index (CVI) by expert opinion; exploratory factor analysis (EFA); and internal consistency by Cronbach's alpha. All study participants gave written informed consent and the cantonal ethics committee waived further ethical approval. Results: The cognitive interviews led to replacement of single-item wording. We retained 27 items for CVI analysis. The averaged overall CVI was 0.79, with 15 items ?0.89. 185 students (70 medicine, 51 nursing, 48 physiotherapy, and 16 midwifery) contributed with data for the EFA and it produced three subscales. "Teamwork, roles, and responsibilities" with factor loadings ?0.49, "Patient-centeredness" with factor loadings ?0.31, and "Community-centeredness" with factor loadings ?0.57. Two items of the total scale were deleted, and four items were redistributed to another subscale. Cronbach's alpha for the overall G-IPAS scale was 0.87. After deleting and redistributing items in subscales, a new Scale-CVI/Average was calculated and was 0.82. Conclusions: Based on a rigorous validation process, the G-IPAS provides a reliable tool to assess attitudes towards interprofessional education among different healthcare professions in German-speaking countries.

Project description:Diabetes related distress is common in type 1 diabetes patients (T1D). High levels of diabetes distress are related to poor metabolic control. An instrument to evaluate diabetes distress in T1D patients is "type 1 diabetes scale-T1DDS". The aim of this study was to translate and culturally adapt the T1DDS into Brazilian culture.T1DDS scale was translated into Portuguese. Back translation was performed and evaluated by a specialists committee. Pre-test was performed with 40 T1D outpatients at State University of Campinas hospital. Internal consistency, external consistency and re-test were performed.72% women, mean age: 32, 1 ± 9, 7 years, mean diabetes duration: 15, 8 ± 9, 1 years, mean scholarity: 11, 5 ± 3, 6, glycosylated hemoglobin mean: 9 ± 2%. Internal consistency: Cronbach alpha of T1DDS Brazilian version was 0.93. External consistency: Spearman's coefficient between T1DDS and PAID, Brazilian version, was 0.7781; (p < 0.0001).The T1DDS Brazilian version is a reliable tool to evaluate diabetes distress in T1D patients in the Brazilian Population. This tool can be useful in clinical care and to identify patiens at risk and in need for psychosocial intervention.

Project description:IntroductionFacial paralysis may occur due to a variety of causes. It is associated to the impairment of some basic daily activities such as eating, drinking, speaking and social communication, which affects the quality of life of these patients. The facial disability index is a short form auto reported outcome questionnaire used to assess patient with facial paralysis. It has been validated and proved to be superior to other general health related quality of life questionnaires.ObjectiveWe aim to do the cultural adaptation and validate the facial disability index into Brazilian Portuguese.MethodsTranslation and cultural-adaptation following the stages recommended by the International Society of Pharmacoeconomics Outcomes Research task force. The questionnaire was administered to 100 patients for evaluation of reliability and validation.ResultsThe reliability of the Portuguese version of the facial disability index was found to be adequate, with a Cronbach's alfa coefficient of 0.73 for the complete scale. Intra-class correlation was 0.79 (95% CI: 0.71-0.85) and 0.85 (95% CI: 0.78-0.89) for the physical and social well-being subscales. There was a significant correlation between the social well-being subscale of the Portuguese version of the facial disability index and the social function and mental health components of the SF-36. There was also a correlation between the facial disability index and the degree of facial dysfunction according to the House-Brackmann global scale.ConclusionThis adapted version of the facial disability index provides a valid and reliable instrument to assess the physical and psychosocial impact of facial nerve dysfunction in Brazilian-speaking patients.

Project description:The Lee Chronic Graft-versus-Host Disease (cGVHD) Symptom Scale has been recommended for use by the 2005 and 2014 National Institutes of Health (NIH) Consensus Conferences to capture cGVHD symptoms. Although the cGVHD Symptom Scale was previously validated, this study aims to reexamine the instrument's content validity by exploring the clarity, comprehensibility, relevance, and ease of use in a contemporary cGVHD sample, toward Food and Drug Administration (FDA) qualification of this patient-reported outcomes (PRO) instrument as a drug development tool. Attaining FDA qualification means that an instrument has been judged to be a reliable and valid measure of clinical benefit. Twenty adult patients with a median age of 58 year (range, 31 to 79 years) participated. The median duration of cGVHD was 33 months (range, 0 to 134.4 months), and current NIH severity score was mild in 1 patient, moderate in 10 patients, and severe in 9 patients, with a median of 5.5 treatments (range, 0 to 14) ever used for cGVHD. The median summary score was 23 (range, 8 to 51), and the median time to complete the scale was 2 minutes, 7 seconds (range, 1 minute, 8 seconds to 4 minutes). Symptoms of cGVHD were well captured on the Lee cGVHD Symptom Scale, although 4 additional symptoms/signs were mentioned by 15% of the participants. Participants mostly reported that item wording was clear and provided accurate definitions of specific terminologies; however, 7 participants (35%) reported finding 1 or more items in the skin domain unclear, reporting, for example, that rashes and itchy skin seemed synonymous. Two of 19 participants (10.5%) described how their answers would have changed had they been asked about their symptoms within the past month instead of within the past week, owing to recently resolved symptoms. All participants were able to accurately explain the concept of "bother" in their own words and distinguish it from symptom severity or other related symptom attributes. In summary, participants found the Lee GVHD Symptom Scale to be a comprehensive and understandable way to report their cGVHD symptom experience. Future work will focus on options for the recall period, the phrasing of skin items, and whether some very rare symptoms (eg, feeding tube, use of oxygen) should continue to be a part of the scale.

Project description:BackgroundAppetite and symptoms, conditions generally reported by the patients with cancer, are somewhat challenging for professionals to measure directly in clinical routine (latent conditions). Therefore, specific instruments are required for this purpose. This study aimed to perform a cultural adaptation of the Cancer Appetite and Symptom Questionnaire (CASQ), into Portuguese and evaluate its psychometric properties on a sample of Brazilian cancer patients.MethodsThis is a validation study with Brazilian cancer patients. The face, content, and construct (factorial and convergent) validities of the Cancer Appetite and Symptom Questionnaire, the study tool, were estimated. Further, a confirmatory factor analysis (CFA) was conducted. The ratio of chi-square and degrees of freedom (?2/df), comparative fit index (CFI), goodness of fit index (GFI) and root mean square error of approximation (RMSEA) were used for fit model assessment. In addition, the reliability of the instrument was estimated using the composite reliability (CR) and Cronbach's alpha coefficient (?), and the invariance of the model in independent samples was estimated by a multigroup analysis (??2).ResultsParticipants included 1,140 cancer patients with a mean age of 53.95 (SD = 13.25) years; 61.3% were women. After the CFA of the original CASQ structure, 2 items with inadequate factor weights were removed. Four correlations between errors were included to provide adequate fit to the sample (?2/df = 8.532, CFI = .94, GFI = .95, and RMSEA = .08). The model exhibited a low convergent validity (AVE = .32). The reliability was adequate (CR = .82 ? = .82). The refined model showed strong invariance in two independent samples (??2: ?: p = .855; i: p = .824; Res: p = .390). A weak stability was obtained between patients undergoing chemotherapy and radiotherapy (??2: ?: p = .155; i: p < .001; Res: p < .001), and between patients undergoing chemotherapy combined with radiotherapy and palliative care (??2: ?: p = .058; i: p < .001; Res: p < .001).ConclusionThe Portuguese version of the CASQ had good face and construct validity and reliability. However, the CASQ still presented invariance in independent samples of Brazilian patients with cancer. However, the tool has low convergent validity and weak invariance in samples with different treatments.

Project description:BackgroundPsychological factors play an important role in the adequate return of an athlete to sport. Our aim was to perform the translation, cross-cultural adaptation, and validation of the Athlete Fear Avoidance Questionnaire (AFAQ) into Brazilian Portuguese.MethodsWe performed the translation and cross-cultural adaptation and evaluated the structural validity, construct validity, and test-retest reliability. In addition to the AFAQ, we used the Numerical Pain Scale (NPS), Pain-Related Catastrophizing Thoughts Scale (PCTS), Self-Estimated Functional Inability because of Pain Questionnaire for athletes (SEFIP-sport), and Hospital Anxiety and Depression Scale (HADS). We used the exploratory factor analysis (EFA) to analyze the internal structure of the AFAQ. We used the Spearman's correlation coefficient (rho) to determine the magnitude of correlation between the AFAQ and the other instruments. We evaluated the test-retest reliability and internal consistency by means of intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively.ResultsNo adaptation was necessary to produce the AFAQ version in Brazilian Portuguese. We included 160 participants in the study. We identified the one-dimensionality of the AFAQ through the EFA with the implementation of parallel analysis (KMO = 0.83, p < 0.001 in Bartlett's Sphericity test). In construct validity, the magnitudes of correlation between the AFAQ and the other instruments ranged from 0.257 to 0.548. We identified adequate reliability (ICC = 0.85) and internal consistency (Cronbach's alpha = 0.90).ConclusionThe Brazilian version of the AFAQ with one domain and 10 items has adequate measurement properties in injured professional and recreational athletes.

Project description:BackgroundSelf-efficacy concerns individuals' beliefs in their capability to exercise control in specific situations and complete tasks successfully. In people with multiple sclerosis (PwMS), self-efficacy has been associated with physical activity levels and quality of life. As a validated German language self-efficacy scale for PwMS is missing the aims of this study were to translate the Unidimensional Self-Efficacy Scale for Multiple Sclerosis (USE-MS) into German, establish face and content validity and cultural adaptation of the German version for PwMS in Austria. A further aim was to validate the German USE-MS (USE-MS-G) in PwMS.MethodsPermission to translate and validate the USE-MS was received from the scale developers. Following guidelines for translation and validation of questionnaires and applying Bandura's concept of self-efficacy, the USE-MS was forward-backward translated with content and face validity established. Cultural adaptation for Austria was performed using cognitive patient interviews. Reliability was assessed using Cronbach's alpha, Person separation index and Lin's concordance correlation coefficient. Rasch analysis was employed to assess construct validity. Comparison was made to scales for resilience, general self-efficacy, anxiety and depression, multiple sclerosis fatigue and health-related quality of life. Data were also pooled with an historic English dataset to compare the English and German language versions.ResultsThe translation and cultural adaptation were successfully performed in the adaptation process of the USE-MS-G. Pretesting was conducted in 30 PwMS, the validation of the final USE-MS-G involved 309 PwMS with minimal to severe disability. The USE-MS-G was found to be valid against the Rasch model when fitting scale data using a bifactor solution of two super-items. It was shown to be unidimensional, free from differential item functioning and well targeted to the study population. Excellent convergent and known-groups validity, internal consistency, person separation reliability and test-retest reliability were shown for the USE-MS-G. Pooling of the English and German datasets confirmed invariance of item difficulties between languages.ConclusionThe USE-MS-G is a robust, valid and reliable scale to assess self-efficacy in PwMS and can generate interval level data on an equivalent metric to the UK version.Trial registrationISRCTN Registry; ISRCTN14843579 ; prospectively registered on 02. 01. 2019.

Project description:BackgroundInformation on the level of knowledge about cystic fibrosis (CF) among affected people and their families is still scarce.ObjectiveThis study aimed to translate, cross-culturally adapt and analyze the psychometric properties of the Brazilian version of Cystic Fibrosis Knowledge Scale (CFKS).Materials and methodsThe translation and cross-cultural adaptation involved the stages of translation, synthesis of translations, reverse translation, synthesis of reverse translations, review by a multi-professional committee of experts and pre-testing. The reliability, viability, construct, predictive, concurrent and discriminant validity were investigated.ResultsThe sample consisted of 40 individuals with cystic CF, 47 individuals with asthma, 242 healthcare workers and 81 students from the health area. The Brazilian version of the CFKS presented high internal consistency (α = 0.91), moderate floor and ceiling effects, without differences in the test-retest scores. An analysis of factorial exploration identified three dimensions. Confirmatory factor analysis led to an acceptable data-model fit. There was good predictive validity, with a difference in the scores among all the evaluated groups (p <0.001), as well as good discriminant validity since individuals with asthma had greater knowledge of asthma compared to CF (r = 0.401, p = 0.005; r2 = 0.162). However, there was no difference between the diagnosis time and knowledge about CF (r = -0.25, p = 0.11; r2 = 0.06), either between treatment adherence and knowledge about CF (r = -0.04, p = 0.77; r2 = 0.002).ConclusionThe Brazilian version of the CFKS indicated that the scale is able to provide valid, reliable and reproducible measures for evaluating the knowledge about CF.

Project description:IntroductionThe health-related quality of life (HRQOL) of patients with tachyarrhythmia can be negatively influenced by the clinical manifestations. The evaluation of HRQOL with validated instruments can provide valuable information that will contribute to clinical decision-making and treatment. In Brazil, however, there is no available scale that evaluates HRQOL in different types of arrhythmia. The purpose of this study was to adapt the Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia-HRQOL scale (ASTA-HRQOL scale) to the Brazilian culture, and to assess the psychometric properties of the adapted questionnaire.MethodsThe study used a methodological process of cultural adaptation based on international literature guidelines. The analyses were performed with 172 participants, 32 for cultural adaptation and 140 for psychometric validation. Calculation included analysis of reliability by Cronbach's α coefficient, construct validity with convergent validity using the WHOQOL-BREF questionnaire and by the Spearman correlation coefficient, Average Variance Extracted, and assessment of confirmatory factor analysis.ResultsThe translation and adaptation processes showed a satisfactory degree of comprehension and applicability (93% reported them to be easy to understand). Confirmatory factor analysis indicated exclusion of one item from the mental scale, but after qualitative analysis the item was retained. The items presented adequate internal consistency (Cronbach's alpha coefficient = 0.88), and an inverse correlation of moderate magnitude with the physical domain (rho = -0.63) and with the mental domain (rho = -0.58) of the WHOQOL-BREF.ConclusionsThe Brazilian Portuguese version of the ASTA-HRQOL scale, the ASTA-Br-HRQOL scale, can be a valuable tool for use in clinical practice and research.
