The study evaluates the effects of CBSM on psychosocial adaptation (includes measures of negative adaptation \[distress and social disruption\] and positive adaptation \[benefit finding and positive affect\]) at 6-month and 12-month follow-up. The study also evaluates the effects of CBSM on physiological adaptation (includes levels of PM serum cortisol and T-helper-type 1 (Th1) cytokine \[interleukin-2, IL-2, and interferon-gamma, IFN-g, production after anti-CD3 stimulation of peripheral blood mononuclear cells (PBMC).
