Objective: The aims were to: revise the Work Experience Survey-Rheumatic Conditions (WES-RC- UK), a work assessment listing 142 workplace barriers; investigate content validity, reliability, and concurrent validity; update the accompanying WES-RC and WORKWELL Solutions Manuals; and investigate workplace barriers of people with inflammatory arthritis.
Methods: Rheumatology therapists, following vocational rehabilitation (VR) training, assessed participants in the WORKWELL VR trial using the WES-RC. Data were extracted from the WES-RC to identify the frequency of workplace barriers, and from trial baseline questionnaires (e.g., Work Limitations Questionnaire-25 (WLQ-25). Barriers reported by ≤5 participants were considered for removal. WES-RC content validity was assessed by linking to the International Classification of Functioning, Health, and Disability Core Set for VR (ICF-VR). Reliability was assessed using Cronbach's α and concurrent validity by correlating the total number of workplace barriers reported with WLQ-25 scores.
Results: WES-RCs were completed with 116 employed participants: 79% women, age 48.72 (SD 9.49) years, and 57% working full-time. The WES-RC was reduced to 121 barriers. Content validity was good, with 73/90 ICF-VR items linked. Cronbach's α = 0.92, that is, suitable for individual use. Concurrent validity was moderate: WLQ-25 (rs = 0.40). The three most common barriers were Physical Job Demands (100%: e.g., mobility 99%; hand use 74%), Mental, Time, Energy, Emotional Job Demands (91%, e.g., concentration 47%, remembering 41%); Getting Ready for and Travel to Work (87%, e.g., driving 60%).
Conclusion: The WES-RC (UK) has good content validity, reliability, and concurrent validity. The wide range of barriers emphasises the need for biopsychosocial work rehabilitation.
