Note. C = total C path; A = A path; B = B path; C’ = direct C path; imm_w = verbal immediacy within-person effect; imm_b = verbal immediacy between-person effect; neg_w = negative affect within-person effect; neg_b = negative affect between-person effect; SE = sleep efficiency; neg affect = negative affect; CI = 95% confidence interval. Bolded paths are statistically significant.
