  • Arthritis Impact Measurement Scale-2, Brief Symptom Inventory, Job Satisfaction Survey, Occupational Data information, Work History, Employment Status, Financial Information [ Time Frame: Scores at baseline, 3, 6, 12, 24 months ] [ Designated as safety issue: No ]

Enrollment: 89
Study Start Date: October 2003
Study Completion Date: September 2009
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Behavioral: worksite intervention
    Researchers will measure the effects of worksite assessment through educational materials or an on-site work evaluation by an occupational therapist on a person's job satisfaction, capacity to perform work duties, income, health status, and psychological well-being. The two groups involved in the research will either receive educational information or on-site work visits. The scope of the information will either be through educational materials to develop strategies to compensate or one-to-one contact and an individualized work plan. The strategies will include recommendations for work behaviors, ergonomic and body mechanics considerations, and modifications for job tasks, equipment, and space.
Detailed Description:

Arthritis is second only to heart disease as a cause of work-related disability with significant financial costs associated with the loss of work for persons with arthritis. Many persons with arthritis have physical impairments which affect their ability to work, with 50% of persons with rheumatoid arthritis leaving employment within 10 years of diagnosis. Risk factors predicting employability, length of employment and worksite accommodations for workers with arthritis have been well documented. Variables predicting work cessation include blue collar jobs and more physically demanding jobs, an older age of the worker, lower education, perceived job strain, social support of co-workers and supervisors, job satisfaction, and self-efficacy. Recent studies of self-report by persons with arthritis identified the use of worksite accommodations such as others providing assistance at work, job autonomy, time flexibility, and use of special equipment. Unknown is the effect of on-site work interventions. The need exists to determine if the provision of strategies for physical accommodations, worksite modifications, and assistive technologies at the individual's job site improves the ability of persons with arthritis to continue working.

This is a randomized clinical trial to investigate the efficacy of a worksite based intervention to improve the employment outcomes of persons with rheumatoid (RA) or osteoarthritis (OA). Persons with RA or OA who have arthritis related work difficulties will have an occupational therapist provide a worksite evaluation and subsequent training in strategies to accommodate arthritis related physical impairments and improve job performance and satisfaction. Participants in control group will be provided with educational printed materials related for a self-initiated worksite evaluation of musculoskeletal and environmental risks at the worksite for persons with arthritis.
