Research on psychological treatment of depression in inpatients is not conclusive,with some studies finding clear positive effects and other studies finding no significant benefit compared to usual care or structured pharmacotherapy. The results of a meta-analysis investigating how effective psychological treatment is for depressed inpatients are presented. A systematic search in bibliographical databases resulted in 12 studieswith a total of 570 respondents. This set of studies had sufficient statistical power to detect small effect sizes. Psychological treatments had a small (g=0.29), but statistically significant additional effect on depression compared to usual care and structured pharmacological treatments only. This corresponded with a numbersneeded- to-be-treated of 6.17. Heterogeneity was zero inmost analyses, and not significant in all analyses. There wasno indication for significant publication bias. Effectswere not associatedwith characteristics of the population, the interventions and the design of the studies. Although the number of studieswas small, and the quality ofmany studieswas not optimal, it seems safe to conclude that psychological treatments have a small but robust effect on depression in depressed inpatients. More high-quality research is needed to verify these results.

In this thesis several studies are presented that have targeted decision making about case management plans in probation. In a case management plan probation officers describe the goals and interventions that should help offenders stop reoffending, and the specific measures necessary to reduce acute risks of recidivism and harm. Such a plan is embedded in a judicial framework, a sanction or advice about the sanction in which these interventions and measures should be executed. The topic of this thesis is the use of structured decision support, and the question is if this can improve decision making about case management plans in probation and subsequently improve the effectiveness of offender supervision. In this chapter we first sketch why structured decision making was introduced in the Dutch probation services. Next we describe the instrument for risk and needs assessment as well as the procedure to develop case management plans that are used by the Dutch probation services and that are investigated in this thesis. Then we describe the setting of the studies and the research questions, and we conclude with an overview of this thesis.
