Predictors of Work-Related Disability During Early Phases of Breast Cancer Treatment

Objective This study examined the magnitude of work-related disability in post-menopausal women with breast cancer compared to healthy controls. It also examined demographic and clinical correlates of work-related disability in post-menopausal women with breast cancer. Study Design Exploratory secondary analysis of longitudinal study. Outcome Measure The Work Limitations Questionnaire measured the percentage of at-work productivity loss. Results The analysis revealed a significant group by time interaction effect (F(1,40)=4.705, p=.036, partial η2=.105) on work-related disability. Participants with breast cancer (M=2.364, SE=.374) had significantly higher percentage of at-work productivity loss compared to the healthy control group (M=1.263, SE=.392). At baseline, cognitive-emotional symptoms were moderately to strongly associated with work-related disability. At 6 months, physical symptoms were moderately associated with work-related disability. Conclusions Newly, diagnosed women with breast cancer are likely to experience higher rates of work-related disability compared to health counterparts. Healthcare providers should provide intervention to parallel the shift in symptoms which lead to higher work-related disability and job cessation Correspondence: Rachelle Brick, 5055 Forbes Tower, Pittsburgh, PA 15260, Phone: (412) 383 – 4085, Fax: (412) 383-6613.
