Psychopathic Traits of Dutch Adolescents in Residential Care: Identifying Subgroups.

The present study examined whether a sample of 214 (52.8% male, M age = 15.76, SD = 1.29) institutionalized adolescents could be classified into subgroups based on psychopathic traits. Confirmatory Factor Analyses revealed a relationship between the subscales of the Youth Psychopathic traits Inventory (YPI) and the three latent constructs of the original model on which it is based. Latent Class Analyses showed that adolescents showing psychopathic traits could be classified into three subgroups. The first group showed low scores on the grandiose/manipulative dimension, the callous/unemotional dimension, and the impulsive/irresponsible dimension (normal group). The second group scored moderate on the grandiose/manipulative dimension and the callous/unemotional dimension and high on the impulsive/irresponsible dimension (impulsive, non-psychopathic-like group). The third group scored high on all three dimensions (psychopathy-like group). The findings revealed that the impulsive, non-psychopathic like group scored significantly higher on internalizing problem behavior compared to the normal group, while the psychopathy-like and the impulsive, non-psychopathic-like group both scored higher on externalizing problem behavior compared to the normal group. Based on a self-report delinquency measure, it appeared that the psychopathy-like group had the highest delinquency rates, except for vandalism. Both the impulsive and psychopathy-like group had the highest scores on the use of soft drugs.

Frequency and seriousness of parental offending and their impact on juvenile offending

The present study investigated to what extent the frequency and seriousness of parental offending were related to their offspring offending. Police officers in one Dutch province completed a form to register risk factors and the actions undertaken when they came into contact with offenders aged 8-14 years. These juveniles were followed for 18 months to establish whether or not they committed more crimes. In addition, the parents of these children were traced in the police criminal record systems. Data were gathered from 577 children and their parents. Of these children, 34% were exposed to parental criminality, of which 33 delinquents had two criminal parents and 163 had one criminal parent. If both parents were criminal, the child had the highest frequency of offending. Further, the frequency of parental offending was positively related to the frequency of the childs offending. Concerning the seriousness of juvenile crimes, the seriousness of the committed offences of the father showed a positive relation with the seriousness of his childs offending. Unexpectedly, a negative association was found between the seriousness of maternal offending and the seriousness of her child offending. These results offered a better understanding of the influence that parents with a criminal history have on their children. Further research is needed to identify mechanisms underlying this relationship in order to provide appropriate prevention and intervention strategies.

FRIENDS' AND ADOLESCENTS' DELINQUENCY The Moderating Role of Social Status and Reciprocity of Friendships

The current study examined the role of friends’ delinquency, in terms of violent and property offenses and vandalism. Data were collected from 1,025 adolescents and their best friends in 19 Dutch secondary schools. Concerning violent offenses, cross-sectional analyses showed that adolescents with a high-status friend were more likely to commit violent offenses themselves, whereas adolescents with a low-status friend engaging in vandalism had a greater likelihood of perpetrating vandalism than the adolescents with a high-status friend. The adolescent’s violent delinquency and vandalism were positively related to the friend’s delinquency only when the friendship was reciprocal. Longitudinally, adolescents with a high-status friend perpetrating vandalism were more likely to engage in vandalism, whereas those with a low-status vandalistic friend showed a decrease. Finally, having a reciprocal friend who committed property offenses increased the adolescent’s risk of committing similar offenses, whereas adolescents with a unilateral friend showed a decreased risk over time.

Sexual Behavior and Treatment Improvement of Institutionalized Girls

The present study examined the association between sexual behavior and treatment improvement of institutionalized girls. Treatment files of 174 girls (M age = 15.71, SD = 1.14) were analyzed to obtain information about the sexual behavior of girls before admission. Based on their sexual behavior, girls were classified into three subgroups: girls showing sexually normative behavior (29%), girls showing promiscuous behavior (43%), and girls with a history of forced prostitution (29%). A subsample of 95 girls was also asked to complete questionnaires to measure treatment improvement. The findings revealed no differences in self-reported problem behavior between the subgroups at entrance. Over time differences between the subgroups were found, indicating that the girls in the different subgroups might require a different treatment approach. Further research that would include larger samples is needed to explore specific treatment needs.

Study protocol: a randomised controlled trial testing the effectiveness of 'Op Volle Kracht' in Dutch residential care

BackgroundAlthough adolescents are often referred to residential treatment centres because of severe externalizing behaviours, a vast majority demonstrated comorbid symptoms of depression and anxiety. Covert internalizing symptoms in these adolescents might be easily unrecognized and therefore untreated. Adolescents with mild intellectual disability (MID) are overrepresented among youth with both externalizing and internalizing problems. There are yet few treatment programs available for adolescents with both externalizing and internalizing problems.Methods/designThe CBT-based resiliency program, Op Volle Kracht (OVK), which is based on the US Penn Resiliency Program (PRP), was adapted to suit the needs of adolescents with both externalizing and internalizing problems, either with or without MID, in Dutch residential treatment centres. The effectiveness of this group intervention program of eight sessions will be tested in a randomised controlled trial (RCT) with N = 182 adolescents aged 12–16, allocated to either the target intervention plus treatment as usual (OVK + TAU) or treatment as usual only (TAU). The main outcome variables include depressive symptoms (primary), anxiety, behavioural problems, and group therapeutic climate. Cognitive styles and coping styles will be included as possible mediators. Assessments take place at baseline (T1), one week before the start of the program (T2), immediately after the program (T3), and at three months follow-up (T4).DiscussionThe program assets include its wide implementation possibilities due to low costs, the short duration of the program and the delivery by group care workers, and its suitability for adolescents with MID. Further strengths of the present study design include its robust method (RCT), the ecological validity, and the inclusion of possible mediators of treatment effect. The program emphasizes individual risk factors for depression rather than social and family factors. Implications for practice and future research are discussed.Trial registrationDutch Trial Register NTR4836

Using a videogame intervention to reduce anxiety and externalizing problems among youths in residential care: An initial randomized controlled trial

Residential care is among the most intensive forms of treatment in youth care. It serves youths with severe behavioral problems and is primarily focused on targeting externalizing problems. Despite best efforts, effect sizes remain moderate, which may be due to the disregarding of internalizing symptoms – in particular anxiety - and to limitations regarding the delivery model of interventions. This initial randomized controlled trial (n = 37) aimed to examine the effectiveness of a biofeedback videogame intervention (Dojo) as an addition to treatment as usual for youths with and without intellectual disability (ID) in residential care with clinical levels of anxiety and externalizing problems. Dojo targets both anxiety and externalizing problems, and incorporates the principles of conventional treatment, while addressing its limitations. Youths were randomly assigned to play Dojo (eight 30-min gameplay sessions) or to treatment as usual (TAU). Measurements of anxiety and externalizing problems were conducted at baseline, posttreatment, and 4-months follow-up through youths’ self-report and mentor-report. Completers-only analyses revealed decreases in self-reported anxiety and externalizing problems, and mentor-reported anxiety at posttreatment for participants in the Dojo condition compared to the control condition. Only mentor-reported anxiety was maintained at follow-up. No effect was found for mentor-reported externalizing problems. These findings provided preliminary evidence that Dojo is a promising, innovative intervention that engages high-risk youths. Practical implications are discussed.

Who Wants to Participate in Routine Outcome Monitoring? Differences between Youth in Secured Residential Care Who Consent or Refuse the Use of Their Clinical Data for Research and Policy Making

ABSTRACT This study examines the external validity of a nationwide dataset, considering the fact that clients can refuse the extraction of their clinical information to aggregate datasets. Data of 949 youths (56% boys, mean age 15.6 years, SD = 1.49) from six Dutch residential institutions were included. An individual-variables and a person-oriented approach were applied to examine the extent to which the group giving permission to the use of their data for aggregate purposes (66%) is representative for the total population in secure residential youth care. Both static, non-changeable client information as well as dynamic, changeable client information were gathered. Youths who assented to the use of their information were overrepresented amongst the population of some of the participating institutions, and were more often Caucasian. Three start profiles based on the dynamic variables were distinguished. Youths who assent were overrepresented in the most problematic profile, whereas youth who did not assent were overrepresented in the least problematic profile. To improve the external validity and the value of the monitor, it is important to achieve more uniformity between institutions as far as the procedures are concerned, and to find creative ways to increase the assent levels, particularly among ethnic minorities.
