Gender Differences in Stories of Violence and Caring by Preschool Children in Post-Divorce Families: Implications for Social Competence

Themes of violence and caring in the spontaneous play of preschool-aged children in response to a revised version of the Attachment Story Completion Task (Bretherton, Ridgeway, & Cassidy, 1990) were analyzed in relation to their social behavior in child-care settings. All children (n = 66, 39 boys) lived in post-divorce families, primarily in the custody of their mothers. Some story enactments of violence predicted negative social behavior in child-care for both boys and girls. Other story enactments were strongly associated with gender and did not uniformly predict social behavior, suggesting that gender socialization plays a significant role in children's play representations of violence and caring. Implications for children's development and the interpretation of children's play behavior are discussed.     

Evidence-Based Work in the Dutch Welfare Sector

The article addresses the topic of evidence–based workin the welfare sector in the Netherlands. It is argued thatthere is insufficient evidence–based practice in socialwork and the reasons for this are discussed. Ways to developevidence-based practice are discussed and it is recommendedthat welfare professionals and researchers work more closelytogether.     

Model Reduction for Prediction in Regression Models

We look at prediction in regression models under squared loss for the random x case with many explanatory variables. Model reduction is done by conditioning upon only a small number of linear combinations of the original variables. The corresponding reduced model will then essentially be the population model for the chemometricians' partial least squares algorithm. Estimation of the selection matrix under this model is briefly discussed, and analoguous results for the case with multivariate response are formulated. Finally, it is shown that an assumption of multinormality may be weakened to assuming elliptically symmetric distribution, and that some of the results are valid without any distributional assumption at all.     

Interpreting Child Sexual Abuse: The Impact of Victim Response

There is little empirical knowledge about whether the interpretation process of child sex offenders is offense-supportive in nature and contributes to the offending process. Vignettes were developed to compare child sex offenders’ and nonoffenders’ interpretations of child molestation incidents after ambiguous and nonambiguous victim responses. Results showed that child sex offenders’ (N = 60) interpretations did not differ from nonoffenders’ (N = 40) interpretations. Overall, the more ambiguous the child responses, the more child complicity and child benefit was seen. Our results indicate that offense-supportive interpretations are not unique to child sex offenders. The mechanisms that are responsible for whether or not to commit a sexual offense should be unraveled and treated, to prevent deviant processes to be activated.     

A pilot study of CBT versus escitalopram combined with CBT in the treatment of pathological gamblers

We conducted a randomised controlled trial pilot study (N = 30) with two treatment groups: (1) Manualised cognitive behavioural therapy (CBT) (n = 15) and (2) escitalopram combined with CBT (n = 15). Treatment was administered individually and the CBT included weekly sessions for eight consecutive weeks. The treatment with escitalopram lasted for a minimum of 16 weeks (20 mg/day), with an optional continuation for a 6-month follow-up period. Repeated measures ANOVA with modified intent-to-treat analyses were conducted. Results showed significant time effects on all measures for both treatment conditions, although no significant group or time × group effects. The results indicated that both treatments were effective in the short term (effect sizes (ES) ranging from 0.45 to 0.91 for the CBT group and 0.27 to 0.72 for the escitalopram+CBT group), and that adding CBT to escitalopram had no additional statistically significant effect (between-group ES of 0.11 and 0.29 for primary outcome measures at 16-weeks post-treatment).     

Preparation of chemotherapy drugs: Planning policy for reduced waiting times

This study investigates the impact of pharmacy policies on patient waiting time in the Chemotherapy Day Unit of the Netherlands Cancer Institute—Antoni van Leeuwenhoek hospital. The project evaluated whether a reduction in waiting time resulting from medication orders being prepared in advance of patient appointments was justified, given that medications prepared in advance are wasted when patients arrive too sick for treatment. Within this context, we derive analytic expressions to approximate patient waiting times and wastage costs, allowing management to see the tradeoff between these two metrics for different policies. Using a case study and a simulation model, the approximations are evaluated. The use of analytic expressions allows the analysis to be easily repeated when medication costs change or when new medications/protocols are introduced. In the same vein, other hospitals with different patient case mixes can easily complete the analysis in their settings. Finally, the outcome from this study resulted in a new policy at the cancer center which is expected to decrease the waiting time by half, while only increasing pharmacy's costs by 1-2%.
