Content Validity and Feasibility of Worksite Assessment for Return-to-Work Program among Injured Workers

Worksite assessment analyses the demands of a worker’s job task and the skill required to perform the duties. Pertubuhan Keselamatan Sosial (PERKESO) has developed its edition of the worksite assessment for the Return To Work program scheme to evaluate referred insured persons by the PERKESO Case Manager. There were limited studies regarding the validity of worksite assessment that include physical, psychological, environmental and ergonomics aspects. This study aimed to determine the content validity and feasibility of the Worksite Assessment for the Return-to-Work Program. This cross-sectional study involved 16 subjects through purpose sampling: ten Case Managers from various regional PERKESO offices for content and face validity, followed by a qualitative phase on feasibility testing on six insured persons through focus group discussion and telephone interview. This assessment showed good content validity for each item (I-CVI ≥ 0.78) with excellent modified Kappa value (K>0.74) and good face validity (FVI ≥ 0.83). The feasibility study shows that this assessment is a feasible and efficient tool for initial assessment in the Return-to-Work Program. The instrument is a promising tool that can facilitate effective discussions with occupational therapists in planning a suitable intervention plan. However, further investigations are needed to explore this instrument’s construct validity and reliability.
