 Women will be excluded from the study if they lack basic proficiency in Dutch, if they have serious cognitive or psychiatric problems, or serious physical comorbidity that would preclude them from participating in a physical exercise program. Since physical exercise may be contraindicated as a treatment for hot flushes in obese women, 49 patients with a BMI 30 will be excluded from the study. Patients participating in concurrent studies or rehabilitation programs containing psychosocial interventions will also be excluded.
