CFI = comparative fit index; CI = confidence interval; Covariance (int. with slope) = covariance of the mean intercept (baseline severity) with the mean slope describing the average linear change over time; e

^{a}= error variances;*M*_{int}= the mean intercept (baseline severity);*M*_{slope}= the mean slope describing linear change over time; RMSEA = root mean square error of approximation; s^{2}_{int}= between-person variance of the intercept; s^{2}_{slope}= between-person variance of the slope describing linear change over time.↵* Similar to multilevel models or latent growth curve models in other structural equation modeing approaches, β represents the regression of change over each month on prior level.

↵† Significance tests were not conducted for error variances; see Data Analysis for information on the time invariance of anxiety symptom severity.
