CES-D: Center for Epidemiologic Studies Depression Scale; PSS-4: Perceived Stress Scale-4; SF-12v2: 12-Item Short Form Health Survey.

aValues per study visit shown are means (SD); mean 24-week change from baseline values from repeated-measures analysis.

bP value indicates significant change from baseline and 24-week study visit if < .05; obtained from repeated-measures analysis.

cIndicates better health.

dIndicates improvement in health.
