Details
Data from a randomized experiment to reduce post-traumatic stress by two
treatments: Eye Movement Desensitization and Reprocessing (EMDR)
(experimental treatment), and cognitive behavioral therapy (CBT) (control
treatment). 52 children were randomized to one of these two treatments.
Outcomes were measured at three time points: at baseline (pre-treatment, T1),
post-treatment (T2, 4-8 weeks), and at follow-up (T3, 3 months). For more
details, see de Roos et al (2011). Some person covariates were reshuffled.
The imputation methodology is explained in Chapter 9 of van Buuren (2012).
