The relation between intrapersonal and interpersonal staff behaviour towards clients with ID and challenging behaviour: a validation study of the Staff–Client Interactive Behaviour Inventory

A.P.A.M Willems; P.J.C.M. Embregts; G.J.J.M. Stams; X. Moonen

BACKGROUND Interpersonal staff behaviour is one of the instigating factors associated with challenging behaviour in clients with intellectual disabilities (ID). There are several studies focusing on the influence of intrapersonal staff characteristics - such as beliefs, attributions and emotional reactions - on staff behaviour. Little is known, however, about interpersonal staff behaviour itself. This study describes the development and validation of the Staff-Client Interactive Behaviour Inventory (SCIBI), measuring both intrapersonal and interpersonal staff behaviour in response to challenging behaviour in clients with ID. METHOD A total of 292 staff members, employed in residential and community services, completed the SCIBI for 34 clients with ID and challenging behaviour. RESULTS Confirmatory factor analysis of a seven-factor model - with assertive control, hostile, friendly and support-seeking interpersonal behaviour; proactive thinking; self-reflection; and critical expressed emotion as reliable factors - showed an exact fit to the data, indicating construct validity and reliability of the SCIBI. A series of multilevel regression analyses showed higher age of the client to be negatively associated with assertive control. Job experience, level of education, type and sex of staff predicted interpersonal behaviour. Also, intrapersonal staff behaviour, including critical expressed emotion, proactive thinking and self-reflection, predicted interpersonal behaviour. CONCLUSIONS The SCIBI can be used to identify staff intrapersonal and interpersonal behaviour towards clients with ID and challenging behaviour. Results obtained with the SCIBI can provide new directions for individual client treatment plans and staff training programmes.

Sexual abuse involving children with an intellectual disability (ID): A narrative review

I. Wissink; Eveline van Vugt; X. Moonen; G.J.J.M. Stams; J. Hendriks

The current paper provides a narrative review of the literature on sexual abuse, involving children with Intellectual Disability (ID). The thirteen articles that were found and met our criteria vary in their definitions of sexual abuse and in how ID was determined. Still, they do paint a general picture concerning (1) the extent of sexual abuse, (2) the nature of the sexual abuse, and (3) the institutional reactions following sexual abuse of children with ID. Our findings confirm the greater vulnerability of children with ID to become involved in sexual abuse both as a victim and as a perpetrator, and we discuss ways to help strengthening prevention and intervention methods. Nevertheless, more research is needed, as it is still a rather unexplored topic, which is striking in light of the high vulnerability of this group.

Measuring Inappropriate Responses of Adolescents to Problematic Social Situations in Secure Institutional and Correctional Youth Care: A Validation Study of the TOPS-A

G. H. P. van der Helm; W. Matthys; X. Moonen; N. Giesen; Es. van Der Heide; G.J.J.M. Stams

The present study examined the construct, concurrent and divergent validity, and reliability of the “Taxonomy of Problematic Social Situations-Adolescent self-report version” (TOPS-A) in a sample of 128 adolescents placed in Dutch secure juvenile facilities. The instrument measures inappropriate responses of adolescents to problematic social situations at the living group. Confirmatory factor analysis of a four-factor model (inappropriate responses to situations of disadvantage, competition, accepting/giving help, and accepting authority) with a second-order factor (inappropriate responses to problematic social situations) showed an exact fit to the data, indicating construct validity of the TOPS-A. Evidence for concurrent validity was found in associations with aggression and living group climate. Divergent validity could not be reliably assessed. Cronbach’s α reliability coefficients were satisfactory. The TOPS-A is a parsimonious instrument that can be used to assess and target inappropriate responses to problematic social situations in (delinquent) adolescents in secure institutional and correctional youth care.

BACKGROUND Juvenile offenders with intellectual disability (ID) have been largely ignored in the literature of risk assessment, while they are overrepresented in the criminal justice system, and ID is a risk factor for juvenile delinquency and recidivism. The aim of this study was to examine whether there are differences between juvenile offenders with and without ID in the impact of risk factors for recidivism. Both the impact of static and dynamic risk factors were examined. Static risk factors were examined in the criminal history domain and dynamic risk factors were examined in the domains of family, school, use of free time, friends, alcohol/drugs, attitude, aggression and skills. This knowledge is important for both assessment and treatment of juvenile offenders with ID. METHOD The sample consisted of adolescents who appeared before the courts for a criminal act and for whom the Washington State Juvenile Court Assessment (WSJCA) was completed. The group of ID juvenile offenders (n = 102) consisted of juvenile offenders with a formal diagnosis of ID, which means a full scale IQ of less than 70, coupled with significant deficits in adaptive behaviour, with childhood onset. The juveniles of this group are special education students or they have a formal diagnosis of a special education need. The group without ID (n = 526), was a random sample of all juvenile offenders without a formal diagnosis of ID. RESULTS No differences were found between juvenile offenders with and without ID in the impact of risk factors on recidivism in most domains. However, in the skills domain, the relations between all risk factors and recidivism were significantly stronger in adolescents without ID than in adolescents with ID. Although not or only borderline statistically significant, these risk factors were all negatively related to recidivism in adolescents with ID, whereas these risk factors were significantly and positively related to recidivism in adolescents without ID. CONCLUSIONS There are few differences between juvenile offenders with and without ID in the impact of risk factors for recidivism, suggesting that the same assessment methods can be used for juvenile offenders with and without ID. There were, however, differences between juvenile offenders with and without ID in the skills domain. What these differences mean for the treatment of juvenile offenders is yet to be determined. For now it is important to be aware of potential negative (side) effects on recidivism when skills training is offered to juvenile offenders with ID.

Identifying offenders with an intellectual disability in detention in The Netherlands

Hendrien Kaal; X. Moonen; H.L.I. Nijman

Purpose – The Dutch Custodial Institutions Agency has commissioned a number of research projects on offenders with intellectual disabilities (ID) in prison. A continuing problem has been that it is not known what the prevalence of ID in Dutch prisons is, and how to identify ID in individual detainees. The paper aims to discuss these issues. Design/methodology/approach – With this in mind a screening instrument (screener for learning disabilities and intelligence (SCIL)) has been developed that screens for IQ < 85. This instrument has been piloted in four different penitentiary institutes. Findings – The papers briefly describes the results of the studies preceding the pilot before turning to the pilot itself. The pilot shed light on what considerations need to be taken into account when implement screening for ID in the current prison system, and on the potential added value for prison staff of knowing whether a detainee possibly has an ID. In addition, the pilot gave some insight into the characteristics...

“I Don’t Care About What You Want!” The Relation Between Juvenile Delinquents’ Responses to Social Problem Situations and Empathy in Secure Juvenile Institutions

E. J. E. Heynen; G. H. P. van der Helm; I. Wissink; G.J.J.M. Stams; X. Moonen

The present study examined the relation between juvenile delinquents’ responses to social problem situations and empathy in secure juvenile institutions. The sample consisted of 79 delinquent boys (62%) and 49 delinquent girls (38%), aged 12 to 19 years. Results showed problems with accepting authority to be negatively related to both affective and cognitive empathy. Inadequate coping with competition was negatively related to cognitive empathy, whereas problems with receiving or giving help were negatively related to affective empathy. The central role of authority problems suggests that group workers could influence adolescents’ empathy development by helping them to learn to cope with social problem situations.

Correlates of direct care staffs' attitudes towards aggression of persons with intellectual disabilities

Maartje H. Knotter; G.J.J.M. Stams; X. Moonen; I. Wissink

BACKGROUND AND AIM To explain direct care staffs attitudes (responsive or rejecting) towards aggression of clients with intellectual disability (ID), data were collected about client characteristics as well as individual and team characteristics of 475 direct care staff members, working in 71 teams. METHOD AND RESULTS Multilevel analyses revealed that a positive team climate was positively associated with both a rejecting and responsive attitude towards aggression. Senior staff members and females showed a less responsive attitude towards aggression, whereas a relatively high percentage of females in a team and a positive attitude towards external professionals were associated with a more responsive attitude towards aggression. Unexpectedly, staff who experienced less verbal and/or physical aggressive incidents of their clients with ID showed a more rejecting attitude towards aggression. Finally, characteristics of the clients with ID accounted for the largest part of the variance in the attitude towards aggression of direct care staff, in particular psychiatric diagnoses. CONCLUSIONS AND IMPLICATIONS Further research is necessary in order to understand how team processes affect the attitude towards aggression of direct care staff. Further it is recommended to provide direct care staff with knowledge about mental disorders in clients with ID.

Reports of sexual abuse of children in state care: A comparison between children with and without intellectual disability

I. Wissink; Eveline van Vugt; Iris A. M. Smits; X. Moonen; G.J.J.M. Stams

ABSTRACT Background Little is known about the nature and reactions to sexual abuse of children with intellectual disability (ID). The aim was to fill this gap. Method Official reports of sexual abuse of children with ID in state care were examined (N = 128) and compared with children without ID (N = 48). Results Clear signs of penetration or genital touching by male (adolescent) peers or (step/foster)fathers were found in most ID reports. Victims often received residential care and disclosed themselves. Type of perpetrator seemed to affect the nature and reaction to the abuse. Cases of children with and without ID seemed to differ in location and reports to police. Conclusions Screening of (foster)homes seems crucial. Residential facilities should find a balance between independence of children and protection. Care providers should be trained in addressing sexual issues and sexual education, accounting for different types of perpetrators (peers/adults). Uniform reporting guidelines are needed.

Adverse Childhood Experiences in Children with Intellectual Disabilities: An Exploratory Case-File Study in Dutch Residential Care

Jessica Vervoort-Schel; Gabriëlle Mercera; I. Wissink; Emmelie Mink; Peer van der Helm; Ramón Lindauer; X. Moonen

Adverse Childhood Experiences (ACEs) are negative childhood events occurring in a child’s family or social environment, that may cause harm or distress. Children with intellectual disabilities (ID) and their families are underrepresented in international ACEs research, while current insights can also contribute to the improvement of their health and well-being. Deficiencies in intellectual and adaptive functioning and living circumstances can increase their vulnerability to adversities. In the present exploratory study 69 case-files of children referred to a Dutch national center for residential youth care for children with ID were analyzed to assess the prevalence and associations of ACEs. It was found that almost half (49.3%) of the children experienced 2 ACEs from the original ACEs framework or more (M (mean) = 2.1; SD (standard deviation) = 1.8) and that the number of ACEs in children was related to the presence of ACEs in parents. Both child and parental ACEs were also related to attachment- and trauma- and stressor-related disorders. Finally, living circumstances and multiple ACEs from the expanded ACEs framework, especially related to parental characteristics, were found to be related to ACEs in children with ID. This implicates the importance of a transgenerational approach when further investigating the impact of ACEs on mental and physical health in children with ID (intellectual disabilities).
