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).
