MISSING data (Statistics) ,EDINBURGH Postnatal Depression Scale - Abstract
Using linear mixed models (LMM) with restricted maximum likelihood estimation, they showed statistically significant group × time interactions with standard deviations were associated with Edinburgh Postnatal Depression Scale score (B = -2.94, SE = 8.67; I P i <.001). In general, repeated outcome measurements are required to correctly estimate the missing values using LMM.[3] However, this study had only a single follow-up point, and in LMM the baseline measure must be used as a covariate and not as an outcome. Comment & Response B To the Editor b Van Lieshout and colleagues[1] conducted a randomized clinical trial of an online 1-day cognitive behavioral therapy workshop vs waiting list in a population at risk of postpartum depression and evaluated the effect using the Edinburgh Postnatal Depression Scale, a patient-reported outcome measure of depressive symptom severity.
