Self-Estimated Functional Inability because of Pain questionnaire for Brazilian workers with musculoskeletal pain: face and content validity

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.

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

“…In addition to this total score, we calculated a separate score for each body region to produce a score from 0 (no disability) to 4 (maximum disability). The version of the SEFIP-work in Brazilian Portuguese and English are available in a previous study 3 .…”

“…In this study, we analyzed a new instrument that was recently created with the aim of measuring musculoskeletal pain and disability in Brazilian workers: the Self-Estimated Functional Inability because of Pain (SEFIP-work) 3 . This questionnaire allows the regionalized analysis of pain and disability in the body, as well as the NBQ, however, with the positive aspect of generating interpretable numerical scores.…”

“…The SEFIP was initially developed and validated to investigate the musculoskeletal injuries in dancers (SEFIP-dance) 4,5 . However, due to its broad structure, this questionnaire has been adapted for athletes (SEFIP-sport) 5,6 and for workers (SEFIP-work) 3 .…”

“…Considering only the SEFIP-work, the pioneer study conducted by Pinheiro et al 3 evaluated only the content validity. However, other measurement properties need to be investigated to properly support the use of the SEFIP-work in the occupational context 7 .…”

Translation, cross-cultural adaptation and validation of the Work Role Functioning Questionnaire 2.0 into Brazilian Portuguese in a general population

“…In this context, assessment instruments based on self-reporting have been commonly used for occupational health assessment. However, most of these instruments are specific to assess work-related disability with a focus on musculoskeletal dysfunction and pain or postural and biomechanical aspects [ 2 , 3 ].…”
