Regular Physical Exercise Adherence Scale (REPEAS): a new instrument to measure environmental and personal barriers to adherence to regular physical exercise.

OBJECTIVE: To create, develop, and validate a scale that identifies the environmental and personal barriers that make it difficult to adhere to the practice of physical exercise on a regular basis in a population of Brazilian adults. METHODS: We include adult individuals, aged 18-59 years, practitioners or former practitioners of physical exercise, with Brazilian Portuguese as their mother tongue. In the development and validation phases of the process, 6 specialists in the field of the health assessed the content validity: firstly, the specialists were asked to freely list the questions they would ask to investigate the barriers to adherence to regulating physical activity. Secondly, after compiling all the suggestions listed and eliminating suggestions with similar content, the items suggested in the first round were sent to the specialists so that an evaluation of all questions using a 5-point Likert scale and the content validity coefficient was calculated. We then evaluated the structural validity, construct validity, reliability, internal consistency, and ceiling and floor effects of the Regular Physical Exercise Adherence Scale (REPEAS). RESULTS: Sixteen items were proposed to measure the factors that make it difficult to adhere to the regular practice of physical exercise. The internal structure of the REPEAS initially tested was based on the theoretical proposal of creating the instrument with two domains. After the structural analysis, we used the modification indices to identify the redundant items of the instrument. Consequently, the final version of the REPEAS after factor analysis had 12 items. Thus, the structure with 2 domains and 12 items presented adequate fit indices. With regard to construct validity, the REPEAS scores were compared in two distinct groups: irregular practitioners/ex-practitioners versus regular practitioners of physical exercise, in which a significant difference could be observed between groups (p < 0.001) for both the domains. Acceptable reliability was observed for the environment and personal domains, with ICC values of 0.86 and 0.94, in the same order. For internal consistency, Cronbach's alpha value was 0.908 (environmental domain) and 0.915 (personal domain), these values being adequate for the REPEAS. CONCLUSION: The REPEAS is a scale with a valid two-dimensional internal structure, consisting of 12 items, reliable and with a valid construct, which supports its use in the clinical, epidemiological, and research contexts in Brazil.

Self-Estimated functional inability because of pain questionnaire for workers: a reliability and construct validity study.

OBJECTIVE: The objective of this study was to investigate the reliability and construct validity of the Self-Estimated Functional Inability because of Pain questionnaire for workers in a sample of Brazilian workers with musculoskeletal pain. METHODS: This is a questionnaire validation study. Workers with musculoskeletal pain were included. Besides the Self-Estimated Functional Inability because of Pain questionnaire for workers, we used the following instruments to perform construct validity: the Work Ability Index and the Numerical Pain Rating Scale. A subsample answered the Self-Estimated Functional Inability because of Pain questionnaire for workers in two moments to calculate reliability by means of the intraclass correlation coefficient and internal consistency by means of the Cronbach's alpha. RESULTS: A total of 190 Brazilian workers were included. Regarding the construct validity, we observed a correlation with magnitude above 0.50 between the Self-Estimated Functional Inability because of Pain questionnaire for workers and the Numerical Pain Rating Scale, given that these two instruments have similarity in the construct, and correlations above 0.30 between the Self-Estimated Functional Inability because of Pain questionnaire for workers and the domains 2, 3, and 4 of the Work Ability Index. Regarding reliability, we observed adequate reliability (intraclass correlation coefficient=0.864) and internal consistency (Cronbach's alpha=0.807). CONCLUSION: The Self-Estimated Functional Inability because of Pain questionnaire for workers is a reliable and valid instrument to be used in Brazilian workers with musculoskeletal pain.

Translation, cross-cultural adaptation, and reliability of the Workplace Sitting Breaks Questionnaire into Brazilian Portuguese.

OBJECTIVE: This study aimed to translate, adapt, and analyze the reliability of the Workplace Sitting Breaks Questionnaire (SITBRQ) for use in Brazil. METHODS: This is a cross-sectional study. The translation and cross-cultural adaptation were conducted considering the following six phases: translation, synthesis of translations, back translation, analysis by a committee of experts, test of the pre-final version, and final version. We included workers aged 18 years or above, both genders, and able to understand, read, and write in Brazilian Portuguese. The final version was applied to workers in two moments (i.e., test and retest), with an interval of 7 days, for reliability calculation. RESULTS: In the translation and cross-cultural adaptation phase, the pre-final version was applied to a sample of 35 workers. For item a of the SITBRQ, there was 100% understanding by respondents, while item b was understood by 94.28%. The reliability phase was conducted with 115 workers. For both items, almost perfect was identified with kappa >0.81. CONCLUSIONS: The SITBRQ version into Brazilian Portuguese has adequate adaptation and excellent values of reliability.

Self-Estimated Functional Inability Because of Pain Questionnaire for Athletes: A Reliability and Construct Validity Study.

OBJECTIVE: The purpose of this study was to measure the reliability, internal consistency, construct validity, and floor and ceiling effects of the Brazilian version of the Self-Estimated Functional Inability Because of Pain Questionnaire for athletes (SEFIP-sport). METHODS: This was a validity questionnaire study developed in a university community. Athletes or practitioners of any sport undertaking regular practice (weekly frequency of at least twice a week for at least 6 months), with the ability to read and write in Brazilian Portuguese, were included. We evaluated disability by means of the SEFIP-sport and the Roland-Morris Disability Questionnaire for general pain, pain intensity by means of a numerical rating scale, quality of life by means of the Short-Form Health Survey, and predicted disability by means of the Örebro Musculoskeletal Pain Questionnaire. RESULTS: Two hundred and twenty-one athletes or regular practitioners of sport were recruited and included in the study. We observed adequate values of reliability (κ ≥ 0.40, intraclass correlation coefficient = 0.91), internal consistency (Cronbach's α ≥ 0.81), and correlations (r s ≥ -0.376) of the total SEFIP-sport score with the numerical rating scale; the pain, vitality, and social aspects domains of the Short-Form Health Survey; the Roland-Morris questionnaire; and the Örebro Musculoskeletal Pain Questionnaire. CONCLUSION: The Brazilian Portuguese version of the SEFIP-sport demonstrated adequate psychometric properties for use in athletes.

Brazilian Version of the Self-Estimated Functional Inability Because of Pain in Dancers: A Validation Study.

OBJECTIVE: The purpose of this study was to measure the reliability, internal consistency, construct validity, and floor and ceiling effects of the Brazilian version of the Self-Estimated Functional Inability because of Pain (SEFIP-dance) instrument. METHODS: This was a questionnaire validation study. Both professional dancers and those who use dance as a recreational activity were included in the study. For test-retest reliability, SEFIP-dance was administered to the same dancer at 2 different times, with an interval of 7 days between the moments. For construct validity, Spearman's correlation coefficient (r s) was used to determine the magnitude of the correlations between SEFIP-dance and the Numerical Rating Scale, the 36-Item Short-Form Health Survey, the Roland-Morris Disability Questionnaire for general pain, and the Örebro Musculoskeletal Pain Questionnaire. RESULTS: A total of 111 dancers were recruited and included in the study. From this total sample, a subsample of 31 was used for the calculations of test-retest reliability: when considering each item of SEFIP-dance, we observed adequate κ values (κ ≥ 0.52); considering the total score, we observed excellent reliability (intraclass correlation coefficient = 0.94). In addition, we identified adequate values for internal consistency (Cronbach's α ≥ 0.80). We observed significant correlations of the SEFIP-dance total score with the Numerical Rating Scale, 36-Item Short-Form Health Survey, the Roland-Morris questionnaire, and the Örebro Musculoskeletal Pain Questionnaire (r s varying between 0.248 and 0.489). Ceiling and floor effects were not observed. CONCLUSION: This study found that the Brazilian Portuguese version of SEFIP-dance has psychometric properties suitable for its use in dancers.

Seated Single-Arm Shot-Put Test to Measure the Functional Performance of the Upper Limbs in Exercise Practitioners With Chronic Shoulder Pain: A Reliability Study.

OBJECTIVE: To measure the intra- and interrater reliability of the seated single-arm shot-put test (SSPT) in the functional performance of the upper limbs of regular physical exercise practitioners with shoulder pain. METHODS: This is a reliability study. Thirty individuals regularly practicing any sports modality that uses the upper limb effectively for at least 6 months, both sexes, ages between 18 and 30 years, with chronic shoulder pain were included. Chronic shoulder pain was measured by means of the shoulder pain and disability index, numerical rating scale, and catastrophic thoughts about pain scale. Functional performance of the upper limbs was measured by means of SSPT. RESULTS: Excellent intrarater reliability was found, with intraclass correlation coefficient ≥0.93, standard error of the measurement values ≤4.63%, and minimum detectable change values for absolute and normalized score of 45.11 cm and 9.97, respectively. Excellent interrater reliability was found, with intraclass correlation coefficient ≥0.96, standard error of the measurement values ≤3.55%, and minimum detectable change values for absolute and normalized score of 32.29 cm and 7.70, respectively. CONCLUSION: SSPT is a reliable tool for measuring the functional performance of the upper limbs in regular exercise practitioners with chronic shoulder pain.

Self-Estimated Functional Inability because of Pain questionnaire for Brazilian workers with musculoskeletal pain: face and content validity / Questionário Self-Estimated Functional Inability because of Pain para trabalhadores brasileiros com dor musculoesquelética: validade de face e de conteúdo / El cuestionario Self-Estimated Functional Inability because of Pain destinado a trabajadores brasileños con dolor musculoesquelético: validez aparente y de contenido

ABSTRACT Our study aimed to perform the face and content validity of Self-Estimated Functional Inability because of Pain (SEFIP) for workers, here called the SEFIP-work questionnaire. This is a questionnaire validity study. Our group previously translated and adapted the original version of the SEFIP, which was developed to investigate musculoskeletal pain and dysfunction to be applied to dancers (SEFIP-dance). However, due to the broad scope of the SEFIP-dance, we made changes and adaptations in the Brazilian Portuguese version of the SEFIP-dance to allow its use in workers. Therefore, face and content validity were performed for the development of the SEFIP-work based on opinions of committee of occupational disease and rehabilitation experts. After face and content validity, this SEFIP-work version was applied to 30 working individuals with musculoskeletal pain. The participants were native Brazilian Portuguese speakers aged 18 years and older. Thus, three changes were made to the questionnaire. All participants understood the SEFIP-work items and alternatives. The average total SEFIP-work score was 6.59 (SD=3.66), with the item "parte inferior das costas" (lower back) being the most marked (n=28; 93.33%), with an average score of 1.18 (SD=0.73). In conclusion, the Brazilian Portuguese version of SEFIP-work presents an acceptable level of understanding by workers in the investigation of musculoskeletal pain or discomfort.

RESUMO Este estudo teve como objetivo verificar a validade de face e conteúdo do questionário Self-Estimated Functional Inability because of Pain (SEFIP) para trabalhadores, aqui chamado de questionário SEFIP-work. Este é um estudo de validade do questionário. Nosso grupo já traduziu e adaptou a versão original do SEFIP, que foi desenvolvido para investigar a dor musculoesquelética e disfunção a ser aplicada a dançarinos (SEFIP-dance). No entanto, devido ao amplo escopo da SEFIP-dance, fizemos mudanças e adaptações na versão traduzida e adaptada ao português brasileiro para permitir o seu uso com trabalhadores. Assim, a validade de face e conteúdo foram realizadas para o desenvolvimento do SEFIP-work baseadas em pareceres de especialistas em doenças ocupacionais e reabilitação. Após a validade de face e de conteúdo, esta versão da SEFIP-work foi aplicada a 30 indivíduos que trabalham com dor músculoesquelética. Os participantes eram falantes nativos de português brasileiro com idade igual ou superior a 18 anos. Assim, foram introduzidas três alterações no questionário. Todos os participantes entenderam os itens e alternativas da SEFIP-work. O escore total médio da SEFIP-work foi de 6,59 (DP=3,66), com o item "parte inferior das costas" sendo o mais marcado (n=28; 93,33%), pontuação média de 1,18 (SD=0,73). Em conclusão, a versão brasileira adaptada da SEFIP-work apresenta um nível aceitável de compreensão por parte dos trabalhadores na investigação da dor ou desconforto músculoesqueléticos.
