N= 952 women (27,130 weekly journals). Results are adjusted odds ratios (aOR) and 95% confidence intervals (CI) from univariate, full and reduced multi-level, mixed-effects logistic regression models estimating effect of moderate/severe stress symptoms on the odds of sexual intercourse each week, controlling for a random effect for the woman and number of number of journals completed. P-values significant for two-tailed alpha at <0.05*, <0.01**, and <0.001***; ^p-value marginal at p<0.10. Stress and background covariates were measured at baseline

^aPerceived Stress Scale - 4 (PSS-4) - 9-point cut-off for moderate/severe stress symptoms. When modeled as a 4-level categorical combined mental health symptom variable (no symptoms, moderate/severe stress symptoms only, moderate/severe depression symptoms only, comorbid stress and depression symptoms) (not shown), point estimates for stress and comorbid stress/depression similar to those shown for stress.
