Support Group Intervention in Primary Breast Cancer : Health-Related Quality of Life, with Special Reference to Anxiety, Depression and Fatigue

• The aim of this thesis was to investigate in a (RCT) the effect of support group intervention in women with primary breast cancer in the short term, and with a long-term follow-up. Women with primary breast cancer were randomized between April 2002 and November 2007 and stratified according to adjuvant treatment with chemotherapy. Of 382 eligible patients, 191+191 patients were randomized to intervention and control groups respectively. Control patients were subjected to standard follow-up procedures. Patients in the intervention group received support intervention at the Foundation of Lustgården Mälardalen during one week followed by four days of follow-up two months later. Patients in intervention and control groups filled in questionnaires at baseline, after 2, 6 and 12 months and in the long-term follow-up after a mean of 6.5 years. In paper I, we studied the effect of the intervention on anxiety and depression measured by the HAD scale and we could show that a significantly lower proportion of women in the intervention group had high anxiety scores compared with women in the control group after 12 months; however, the proportion of women with high depression scores were unaffected. In paper II, we studied the effect of the intervention on fatigue and health-related quality of life (HRQoL) measured by the Norwegian version of the fatigue questionnaire (FQ) and EORTC-QLQ 30 and BR 23.We could not demonstrate any significant effect of the intervention. In paper III, we studied the effect of the intervention on sick-leave, healthcare utilization and the effect of the intervention in economic terms. We used a specially formulated questionnaire. There was a trend towards longer sick leave and more health-care utilization in the intervention group. The difference in total costs was statistically significantly higher in the intervention group after 12 months (p= 0.0036). In paper IV, we studied the long-term effects of the support intervention on anxiety, depression, fatigue and HRQoL. We could show a significant effect of the intervention on cognitive function, body image, future perspective and fatigue, the largest effect was seen among women who received chemotherapy; however, no effects on anxiety and depression were demonstrated.
