Sample size calculations for the main intervention component were based on results of a survey of fatigue and quality of life among breast cancer survivors 1 to 5 years following the diagnosis of breast (Bower 2000). That study used the energy/fatigue subscale of the SF-36 Health Survey (Ware 1992.). That instrument has also been shown to correlate with the Piper fatigue scale, an instrument specifically designed and evaluated among breast cancer patients (Piper 1998). We will administer both survey instruments but will base sample size estimates on the SF-36, a more widely used health survey instrument.
