Purpose: The aim of this study was to document the psychological well-being of a group of women with invasive breast cancer (BC) on an average of nearly 2 years after their diagnosis.
Methods: Participants were women in the Medical Benefits Fund Australia Limited Foundation Health and Wellbeing after Breast Cancer Study, a cohort study of 1,684 women recruited within 12 months of their diagnosis with invasive BC, who completed their first annual follow-up questionnaire. Psychological well-being was measured using the Psychological General Well Being Index questionnaire (PGWB) in women with BC.
Results: The PGWB questionnaire was completed by 1,589 women on an average of 92 weeks after their BC diagnosis, of whom 46 had evidence of active disease. PGWB total scores for all age groups of the BC cohort were lower than community-based norms (p < 0.001 for age groups > or =70, 60-<70, 50-60; p = 0.002 for age group 40-<50 and p = 0.05 for age group <40). PGWB total scores for the BC cohort were positively associated with age (p < 0.001) and living with others (p < 0.01) and inversely associated with active disease (p < 0.001) and education beyond secondary school (p = 0.03). For the domain of anxiety, there was no statistically significant association with living with others but an inverse association with education beyond school.
Conclusion: A higher level of education may be associated with increased anxiety and lower well-being. Social support is particularly important for women with BC who are known to live alone.
