between admission and discharge on the SCL-90-R) of individuals with EO and AO 1 disruptive behavior.
The majority of known pre-treatment characteristics predictive of dropout are related to disruptive behavior (De Haan et al., 2013). Surprisingly enough, little is known about the factors predicting dropout among adolescents treated for severe disruptive behaviour, despite the fact that it is very likely that dropout is a major problem in this specific group. Therefore, the aim of Chapter 5 was to examine pre- treatment characteristics predictive of dropout within individuals with disruptive behavior. Beside EO disruptive behavior, specific types of disruptive behavior and their relation to dropout were considered.
As follow-up research focuses predominantly on patients who completed the treatment, we lack information on the outcomes of treatment dropouts. Therefore in Chapter 6, the long term outcome of the dropouts and completers of the orthospychiatric facility was examined. We investigated whether completion of treatment could predict good general daily functioning 18 months after discharge. To control for the possible effect of the factors (of Chapter 5) that had been associated with dropout in our sample, the influence of EO disruptive behavior, cannabis usage prior to admission and male sex was also examined.
Finally, Chapter 7 provides a general discussion of main findings and conclusions of chapters 2-6. The results found in the previous chapters are summarized and strengths and limitations are discussed. This thesis concludes with some implications for clinical practice and recommendations for future research.
