Major research studies have only concentrated on the effect of ergonomics to WRMSD. However, more researches have come into surface for the study of the relationship between psychosocial stress factors at workplace with WRMSD. In this research study, there are 6 variables under the psychosocial risk factors which being set and determined as independent variables whereas WRMSD being set as dependent variable. The 6 factors mentioned here are job demand (JD), role expectation (RE), work control (WC), social interaction (SI), leadership influence (LI), as well as organizational culture (OC). A total of 50 sample sizes have been taken and the correspondents comprised of employees working in the shared service companies located in Kuala Lumpur and Selangor.

Two type of questionnaire being used merged into one are : part 1 (QPS-Nordic questionnaire) and part 2 (Standardized Nordic questionnaire for musculoskeletal symptoms). Quantitative analysis has also been used for this study where out of the 6 factors, 4 risk factors have shown positive relationship with WRMSD. The 4 factors are JD (χ2=15.111, DF=2, P<0.05), RE (χ2=15.130, DF=2, P<0.05), WC (χ2=6.106, DF=2, P<0.05) and OC (χ2=9.051, DF=2, P<0.05). It is believed that by the effectiveness of recommendations given at the end of this studies may help to cope and eventually minimizing WRMSD at the workplace.
