Notes. Time2 represents the quadratic term (time*time), which tests for nonlinear changes over time; EDE=Eating Disorder Examination global score.
p < .001.
Significant intercept of the fixed effects column indicates initial value (intercept) is significantly different from zero; significant intercept of the variance column indicates that there is significant variance (differences across individuals) in initial levels (intercept).
