Note. Unstandardized estimates and standard errors. Model is based on up to 63 daily reports nested within 150 participants for a total of 8,562 observations. An additional multilevel model was tested that included time-invariant covariates (sex, ethnicity, income, body mass index, Big 5 personality characteristics, and functional limitations, role limitations due to physical health, pain, and general health [from the SF36]); however, adding these covariates did not change the findings from this analysis so we present the more parsimonious model. −2LL = −2 Log Likelihood. AIC = Akaike Information Criterion.
p < .05.
