Multilevel Models Examining Blood Pressure as a Function of Chronic Stress, Negative Relationship Quality, and Gender

	Model 1: Direct effects of stress and NRQ	Model 2: Do direct effects vary by gender?	Model 3: Moderating role of negative quality on stress–BP link	Model 4: Does the moderating role vary by gender?

Change in likelihood	20.4**	17.3**	10.2*	17.3*

Notes: BP = blood pressure; NRQ = negative relationship quality. Change in likelihood in Model 1 is based on comparison with a covariates-only model. Change in likelihood for Models 2 and 3 is change from Model 1. Change in likelihood of Model 4 is based on comparison with Model 3. To compare model fit across models, we restricted all four models to individuals with complete data on all predictors and covariates (N = 2,221).
