Mediating processes of two communication interventions for breast cancer patients.

Objective: Test whether three mediating processes of Self-Determination Theory are involved in intervention effects on quality of life for breast cancer patients.

Methods: A randomized clinical trial recruited newly diagnosed breast cancer patients for 6 months of (1) Internet training and access, (2) access to an integrated eHealth system for breast cancer (CHESS), (3) a series of phone conversations with a Human Cancer Information Mentor, or (4) both (2) and (3).

Results: This paper reports results after the initial 6 weeks of intervention, at which point patients in the combined condition had higher quality of life scores than those in the other three conditions.
