SF-36 Mental Component Scale	1.4	2.06	.49
Perceived Stress Scale	.09	1.33	.94

Note: POMS = Profile of Mood States; SF-36 = Medical Outcomes Scale, Short-Form; positive/negative support = the ratio of positive to negative abstinence-specific social support; b = regression coefficient; SE = standard error. Regression coefficients with p-values of less than .05 are presented in bold.
