Een onderzoek naar de programmatheorie en de -uitvoering van de ITB harde kern en ITB-CRIEM

Individual Track Guidance (ITG) (referred to in the Netherlands as Individuele Traject Begeleiding  or ITB is an intensive form of (juvenile) probation, often imposed as an alternative to detention or part thereof. The aim of ITG is to prevent recidivism by furthering social integration and improving youth’s personal skills. There are two variations of ITG: Hard-core ITG and CRIEM1-ITG. Hard-core ITG entails intensive guidance of adolescents (12- to 17-year-olds) and young adults between the ages of 18 and 24. CRIEM-ITG is aimed at youth from non-Western backgrounds who are apprehended for a first offence or have committed a number of minor offences. ITB staat voor individuele trajectbegeleiding en is een intensieve vorm van (jeugd)reclassering, die vaak wordt opgelegd als alternatief voor een (deel van een) detentiestraf. Het doel van ITB is het voorkomen van recidive door vergroting van de sociale integratie en door verbetering van de persoonlijke vaardigheden van de jongere. Er zijn twee vormen te onderscheiden: ITB-HK (voor harde kern-jongeren) en ITB-CRIEM (voor jongeren uit etnische minderheden). Dit onderzoek is in eerste instantie beperkt tot het achterhalen van de programmatheorie en het uitvoeren van een programma-evaluatie

The effects of changes in the order of verbal labels and numerical values on children's scores on attitude and rating scales

Research with adults has shown that variations in verbal labels and numerical scale values on rating scales can affect the responses given. However, few studies have been conducted with children. The study aimed to examine potential differences in children’s responses to Likert-type rating scales according to their anchor points and scale direction, and to see whether or not such differences were stable over time. 130 British children, aged 9 to 11, completed six sets of Likert-type rating scales, presented in four different ways varying the position of positive labels and numerical values. The results showed, both initially and 8-12 weeks later, that presenting a positive label or a high score on the left of a scale led to significantly higher mean scores than did the other variations. These findings indicate that different arrangements of rating scales can produce different results which has clear implications for the administration of scales with children

Interpersonal and affective dimensions of psychopathic traits in adolescents : development and validation of a self-report instrument

We report the development and psychometric evaluations of a self-report instrument designed to screen for psychopathic traits among mainstream community adolescents. Tests of item functioning were initially conducted with 26 adolescents. In a second study the new instrument was administered to 150 high school adolescents, 73 of who had school records of suspension for antisocial behavior. Exploratory factor analysis yielded a 4-factor structure (Impulsivity α = .73, Self-Centredness α = .70, Callous-Unemotional α = .69, and Manipulativeness α = .83). In a third study involving 328 high school adolescents, 130 with records of suspension for antisocial behaviour, competing measurement models were evaluated using confirmatory factor analysis. The superiority of a first-order model represented by four correlated factors that was invariant across gender and age was confirmed. The findings provide researchers and clinicians with a psychometrically strong, self-report instrument and a greater understanding of psychopathic traits in mainstream adolescents

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

Safety and efficacy of combined portal and hepatic vein embolisation in patients with colorectal liver metastases (DRAGON1): a multicentre, single-arm clinical trial.

peer reviewed[en] BACKGROUND: Major liver resection is often required for complete clearance of colorectal liver metastases (CRLM). Patients with insufficient future liver remnant (FLR) volume/function are at high risk of post-hepatectomy liver failure (PHLF) and require FLR hypertrophy-inducing procedures to enable safe resection. The most recent variant of these procedures is combined portal and hepatic vein embolization (PVE/HVE). The DRAGON 1 trial evaluates the safety and efficacy of PVE/HVE, while assessing recruitment potential for the DRAGON 2 randomized trial. METHODS: DRAGON 1 is a prospective, single-arm, international, multicenter trial. Patients with upfront unresectable CRLM due to a small FLR were included. The primary outcome was the ability of centers to recruit three patients and perform PVE/HVE and liver resection without 90-day mortality. Secondary outcomes included recruitment capacity, PVE/HVE technical details, FLR volume changes, complications, and resection rates. The study is registered at ClinicalTrials.gov, identifier: NCT04272931. FINDINGS: In total, 102 patients were included from 43 centers. Twenty-four centers (24/43 = 56%) recruited three or more patients, and 20 centers (20/43 = 47%) achieved this without 90-day mortality. Of 96 patients undergoing PVE/HVE, no post-embolization mortality occurred, though major complications were reported in two patients. Resection was completed in 86 patients (86/96 = 90%), with seven patients (7/86 = 8%) dying within 90 days. PHLF grade B/C (International Study Group of Liver Surgery criteria) occurred in 19 patients (19/86 = 22%). INTERPRETATION: DRAGON 1 demonstrates that PVE/HVE is safe, with no embolization-related mortality, low morbidity, and high resection rates in upfront unresectable CRLM.

Self-reported psychopathic traits and socio-emotional functioning in 9-12 year old children from the community

The aim of this thesis was to enhance our understanding of the concept of psychopathic traits in preadolescent children. It did so by investigating a new assessment tool providing a previously unexplored perspective on psychopathic traits in preadolescent children: that of the child itself. This is important because children are in the unique position to report on feelings, attitudes and behaviors across a range of situations, including the home, the classroom and the playground. Furthermore, it sought to provide a deeper understanding of the nature of psychopathic traits and their relations to problematic socio-emotional functioning. It was concluded that psychopathic traits can be indeed measured reliably and meaningfully through self-report in 9 to 12 year olds. Furthermore, children with high levels of psychopathic traits were shown to suffer from impaired social functioning emotionally, motivationally, and interpersonally. These problems may be important targets for future interventions for this group. Finally, it was demonstrated that that children with psychopathic traits are prone to act aggressively, but also that this aggression is dynamic and is dependent upon circumstances. Their aggression can be attenuated by a salient display of others__ distress. These results suggest that empathy based treatment techniques may reduce aggression in children with psychopathic traits.UBL - phd migration 201
