Appraisal and psychological distress six months after diagnosis of breast cancer.

OBJECTIVES: Four in ten women with breast cancer experience high levels of anxiety or depression, despite advances in oncology treatments. The study investigates the role of psychosocial, disease and treatment characteristics, and appraisal processes to better understand factors contributing to this high psychological morbidity. DESIGN: A postal survey was employed to observe psychological morbidity in women 2 and 6 months after initial diagnosis and treatment of breast cancer. The study was conducted as an adjunct to an Australian multi-centre feasibility study of an evidence-based specialist breast nurse (SBN) model of care. METHODS: In total, 195 women with a new diagnosis of early or locally advanced breast cancer completed the data collection relating to this study. Psychosocial, disease and treatment information for each woman at diagnosis was recorded in research logs. Women completed the GHQ-12 questionnaire 2 months after diagnosis, and at 6 months they completed the GHQ-12 and an appraisal process questionnaire designed by the National Breast Cancer Centre (NBCC). Bivariate and multiple regression analyses were undertaken to build a statistical model to account for GHQ-12 scores at 6 months. RESULTS: According to the GHQ-12, 43% of women had a likely affective disorder at either 2 or 6 months after diagnosis. Point prevalence decreased from 2 to 6 months yet remained substantial compared with general population statistics. Psychological functioning in women with breast cancer is related to a woman's psychiatric history, grade of tumour, and her appraisal processes. Most importantly, improved psychological functioning from 2 to 6 months after diagnosis is related to a woman having a lower primary appraisal of threat and a greater secondary appraisal of self-efficacy in terms of having confidence in her own ability to cope with concerns associated with the illness. CONCLUSION: Appraisal processes play a significant role in psychological adjustment to breast cancer. Adjustment may be facilitated by ensuring that the treatment team responds to shortfalls in a woman's appraisal of her illness and her perceived ability to cope, especially where a difficult prognosis is evident.
