Abstract

Ergonomic risk assessment is essential to the identification of the risk factors for musculoskeletal disorders among workers. This study is a systematic review on occupational health studies that have been done in Thailand during 1996-2016 from 12 available databases. There were 428 studies related to occupational health research from the first search. After the screening base on given criteria, there were 16 studies that were included in the analysis. Contents for analyses included the descriptive information of the instruments, instrument contents, implementation characteristic, and psychometric properties. The principle results showed that there were 3 types of ergonomic risk assessment in Thai occupational health research; self-administer questionnaire, interview form, and observational instrument. The first two types were mostly developed by the authors while the last type adopted from the existing standard instruments. The review found a diversity of the instruments used in assessing ergonomic risk factors in various work settings. There was a huge range of the number of study samples in the studies from 15 to a thousand. Both interview and observational types had a complete response rate while self-administration type obtained average 91.7% response rate. Regarding to the psychometric performance characteristics, about half of the reviewed studies provided limited information about psychometric properties of the instruments. However, the remaining studies indicated the values of psychometric tests as good to excellent. In conclusion, our review indicated a diversity of instruments in assessing ergonomic risk factors. This provides a wide range of instruments to be chosen. Our recommendation based on the review results would be the modification on these available instruments. It would be beneficial to use more than one type of instrument administration. Then all potential ergonomic risk factors are inclusively identified for further appropriate intervention
