The association between aggressive behaviour and non-suicidal self-injury and shared risk factors in adults with mild intellectual disability.

BACKGROUND: Aggressive behaviour (AB) and non-suicidal self-injury (NSSI) are common in people with mild intellectual disability or borderline intellectual functioning, leading to adverse consequences for themselves and those around them. METHOD: We investigated the relationship between AB (both total and physical in particular) and NSSI and risk factors in 125 residents in a treatment clinic using incident reports and standard clinical measurements. RESULTS: There was a weak correlation between AB and NSSI, as well as between impulsivity and total AB, and between coping and AB and NSSI. However, NSSI, impulsivity and coping skills did not predict AB. CONCLUSION: Results do not corroborate those of other studies in this area. In future studies impulsivity, coping, aggression and NSSI may be measured using other instruments, and differences between people with and without intellectual disability regarding these variables may be explored.

Measurement invariance of the group climate inventory across adults with and without mild intellectual disability in secure residential facilities.

BACKGROUND: The Group Climate Inventory (GCI) was tested for measurement invariance across 332 adults with and 225 adults without mild intellectual disabilities in Dutch forensic treatment, and for latent mean differences on its Support, Growth, Repression, and Atmosphere subscales. METHOD: Multigroup confirmatory factor analysis was used to evaluate the configural, threshold, and loading and threshold invariance of the GCI across both groups, and to compare group latent means on each subscale. RESULTS: Measurement invariance was found across groups. Latent mean group comparisons showed small but significant differences reflected in lower scores on Support and Atmosphere in the group with mild intellectual disabilities. CONCLUSION: The GCI allows meaningful comparisons between clients with and without mild intellectual disabilities in secure facilities. Results from the between-group comparisons suggest that consideration should be given as to whether, and why, the support and atmosphere perceptions of clients with mild intellectual disabilities might be less good.

Factors affecting the feelings of safety among individuals with mild intellectual disabilities and severe challenging behaviour in residential care: A qualitative study of professional and service users' perspectives.

Background: This study focuses on what feeling safe means for people with mild intellectual disabilities and severe challenging behaviour, and which factors affect their sense of safety. Method: Thematic analysis was used to analyse data collected during (1) ethnographic longitudinal research and (2) interviews and focus groups among professionals and service users. Results: Feelings of safety can relate to three main themes: (1) a physical environment that reduces risks and temptations; (2) a reliable, predictable, and supportive environment; and (3) an accepting environment that enables service users to establish a normal life. An analysis of which factors affect service users' sense of safety identified 20 themes (e.g. team climate) and 34 subthemes (e.g. interactions with other service users). Conclusions: A range of interconnected factors can affect service users' feelings of safety. Future research should explore what organisations and external actors (e.g. the police) can do to promote those feelings.

The adaptive ability performance test (ADAPT): A factor analytic study in clients with intellectual disabilities.

BACKGROUND: The adaptive ability performance test (ADAPT) was developed to assess adaptive skills in individuals with intellectual disabilities and borderline intellectual functioning, with or without mental disorders. As a follow-up to earlier research on the ADAPT, a factor analytic study was conducted. METHOD: One thousand and sixty six ADAPTs from clients with (suspected) intellectual disabilities or borderline intellectual functioning and 129 ADAPTs from participants from the general population were collected along with other characteristics (e.g., IQ, psychiatric classifications, living situation). RESULTS: An exploratory factor analysis (EFA) was performed and resulted in good fit indices. Subsequent confirmatory factor analysis (CFA) and multigroup CFA showed acceptable to good fit indices. This resulted in an instrument with eight factors and 62 items. CONCLUSION: Factor analytic results suggest that the ADAPT is a valid instrument that measures adaptive skills in individuals with intellectual disabilities or borderline intellectual functioning.

Dietary supplements for aggressive behaviour in people with intellectual disabilities: A randomised controlled crossover trial.

BACKGROUND: Aggressive incidents are common in people with intellectual disabilities. Therefore, we aimed to assess whether supplementation of multivitamins, minerals, and omega-3 fatty acids (FA) reduces aggressive incidents. METHODS: We conducted a randomised, triple blind, placebo controlled, single crossover intervention trial. People with intellectual disabilities or borderline intellectual functioning, between 12 and 40 years of age, and showing aggressive behaviour were included. Participants received either a daily dose of dietary supplements, or placebo. Primary outcome was the number of aggressive incidents, measured using the Modified Overt Aggression Scale (MOAS). RESULTS: there were 113 participants (placebo, n = 56), of whom 24 (placebo, n = 10) participated in the crossover phase of the trial. All 137 trajectories were included in the analyses. There was no significant difference in mean number of aggressive incidents per day between those assigned to supplements and those who received placebo (rate ratio = 0.93: 95% Confidence Interval [CI] = 0.59-1.45). CONCLUSION: In this pragmatic trial, we did not find significant differences in the outcomes between the supplement and placebo arms. The COVID-19 pandemic started midway through our trial, this may have affected the results.

Setting up a new team of support staff for people with mild intellectual disability or borderline intellectual functioning and severe challenging behaviour: A concept mapping study.

BACKGROUND: Studies about teams of staff supporting people with intellectual disability have focused on team performance of existing teams. This study aimed to examine important factors in the process of setting up a new team of support staff. Specifically, we considered the process for a team that supports service users with mild intellectual disability or borderline intellectual functioning who display severe challenging behaviour from the orthopedagogical perspective (i.e., with a focus on contextual factors). METHOD: Three participant groups (service users, support staff, and professionals supporting a team) participated in a concept mapping procedure, including generating statements in interviews and focus groups, sorting, and rating. An expert group interpreted the results. RESULTS: Important factors to one or more groups were: service users and support staff getting acquainted early, team safety, social support, a shared vision, and a positive reputation of the new home. CONCLUSIONS: Four core outcomes were addressed that may help service organisations to provide an environment matching the needs of service users who show severe challenging behaviour from the start.

Diet quality among people with intellectual disabilities and borderline intellectual functioning.

BACKGROUND: We sought to assess diet quality among people with intellectual disabilities or borderline intellectual functioning, living in residential facilities or receiving day care. METHODS: We measured diet quality using the Dutch Healthy Diet Food Frequency Questionnaire (DHD) and compared this between participants with (n = 151) and controls without intellectual disabilities (n = 169). Potential correlates of diet quality were explored. RESULTS: We found lower mean diet quality among people with intellectual disabilities (M = 80.9) compared to controls (M = 111.2; mean adjusted difference -28.4; 95% CI [-32.3, -24.5]; p < .001). Participants with borderline intellectual functioning and mild intellectual disabilities had lower diet quality and higher body mass index than individuals with severe to profound intellectual disabilities. Being female was a predictor of better diet quality. CONCLUSIONS: Overall, we found that diet quality was low in the sample of people with intellectual disabilities or borderline intellectual functioning.

The ADaptive Ability Performance Test (ADAPT): A new instrument for measuring adaptive skills in people with intellectual disabilities and borderline intellectual functioning.

BACKGROUND: Since the DSM-5, adaptive functioning has taken a prominent place in the classification of intellectual disability (ID). The ADAPT was developed to assess adaptive skills in individuals with ID. METHOD: A total of 2,081 ADAPTs from clients with suspected ID or borderline intellectual functioning and 129 ADAPTs from people from the general population (non-ID) were collected, along with background characteristics. RESULTS: Internal consistency of the ADAPT was high (α = 0.98). ADAPT scores were positively associated with IQ, educational level and level of independent living. Furthermore, individuals without ID scored significantly higher than the clients on all of the 65 ADAPT items. Reference values were established for different IQ groups and living situations. CONCLUSION: Results suggest that the ADAPT is a valid instrument for measuring adaptive skills in individuals with ID. The reference values may be used for the purpose of estimating the level of ID and the needed intensity of support.

Group climate, aggressive incidents and coercion in a secure forensic setting for individuals with mild intellectual disability or borderline intellectual functioning: A multilevel study.

BACKGROUND: This study examines associations between group climate, aggressive incidents and coercive measures in adults with mild intellectual disability or borderline intellectual functioning (MID-BIF) of a secure forensic setting. METHOD: Participants (N = 248) were interviewed about their perception of group climate utilizing the Group Climate Instrument. Data on aggressive incidents and coercive measures were retrieved from the facilities' electronic database. A multilevel structural equation model was fitted in which variability in perception of group climate within and between living groups was examined. RESULTS: An open and therapeutic group climate was associated with lower levels of aggression within and between groups. A higher number of aggressive incidents were significantly associated with a higher number of coercive measures. CONCLUSIONS: The findings have implications for the understanding of how group climate may play a role in reducing aggressive incidents at the living group in treatment of individuals with MID-BIF in secure forensic settings.

Psychometric properties of the Dynamic Risk Outcome Scales (DROS) for individuals with mild intellectual disability or borderline intellectual functioning and externalizing behaviour problems.

BACKGROUND: The present study examined the psychometric properties of the Dynamic Risk Outcome Scales (DROS), an instrument developed to measure dynamic risk factors in individuals with mild intellectual disabilities or borderline intellectual functioning (MID-BIF) and externalizing (including offending-like) behaviour problems. METHOD: The sample consisted of 606 clients (86% male) from inpatient treatment wards at a facility for individuals with MID-BIF and externalizing behaviour problems. RESULTS: The DROS showed an acceptable factor structure, good internal consistency, significant test-retest reliability and fair to excellent inter-rater reliabilities for most subscales and total score. Compared to the Adult Behavior Checklist (ABCL; Achenbach & Rescorla, 2003 Manual for the ASEBA adult forms and profiles. Burlington, VT: University of Vermont, Research Center for Children, Youth, & Families), the DROS showed convergent and divergent validity, concurrent and longitudinal validity. CONCLUSIONS: The DROS is a reliable and valid instrument to measure dynamic risk factors in clients with MID-BIF. Future research on the DROS will focus on the assessment of recidivism and the inclusion of internalizing problems.

Experiences of service users with a mild intellectual disability or borderline intellectual functioning with Flexible Assertive Community Treatment: A qualitative study.

BACKGROUND: In the Netherlands, Flexible Assertive Community Treatment (FACT) teams have been established for people with mild intellectual disability (MID) or borderline intellectual functioning (BIF) and mental health problems or challenging behaviour. Little is known yet about service users' experiences with FACT. METHOD: An inductive grounded theory approach was used to explore how service users valued the treatment and their own functioning, and which factors were perceived as supportive. Semi-structured interviews were held with 15 service users. RESULTS: Most service users highly appreciated the contact with the staff and the practical and emotional support. Persistent involvement, availability and humanity, and respect for autonomy were distinguished as core values in the relationship with the staff. Most service users experienced improvement in time and attributed this to intrapersonal changes and/or less stress in life. CONCLUSIONS: From the perspective of service users with MID/BIF, FACT appears to have an added value.

Brief report: Follow-up outcomes of multisystemic therapy for adolescents with an intellectual disability and the relation with parental intellectual disability.

Research on follow-up outcomes of systemic interventions for family members with an intellectual disability is scarce. In this study, short-term and long-term follow-up outcomes of multisystemic therapy for adolescents with antisocial or delinquent behaviour and an intellectual disability (MST-ID) are reported. In addition, the role of parental intellectual disability was examined. Outcomes of 55 families who had received MST-ID were assessed at the end of treatment and at 6-month, 12-month and 18-month follow-up. Parental intellectual disability was used as a predictor of treatment outcomes. Missing data were handled using multiple imputation. Rule-breaking behaviour of adolescents declined during treatment and stabilized until 18 months post-treatment. The presence or absence of parental intellectual disability did not predict treatment outcomes. This study was the first to report long-term outcomes of MST-ID. The intervention achieved similar results in families with and without parents with an intellectual disability.

Substance use among individuals with mild intellectual disability or borderline intellectual functioning in residential care: Examining the relationship between drinking motives and substance use.

BACKGROUND: This study examined the relationship between substance use motives (i.e., social, conformity, coping and enhancement) and substance use in individuals with mild intellectual disability or borderline intellectual functioning (MID-BIF). METHOD: Data were collected among 163 clients with MID-BIF using interactive questionnaires with visual cues on a tablet with a web application. RESULTS: Results show that social motives were positively related to frequency of alcohol use, while conformity, coping and enhancement motives were positively related to severity of alcohol use. Results for drug use show that social motives were positively related to frequency of cannabis and hard drug use and that conformity motives were negatively related to frequency of cannabis use. Coping motives were positively related to severity of drug use. CONCLUSIONS: Insight in substance use motives should be used when adapting interventions, as it could contribute to the prevention and reduction of substance use disorders in individuals with MID-BIF.

Evaluating the effects of multisystemic therapy for adolescents with intellectual disabilities and antisocial or delinquent behaviour and their parents.

BACKGROUND: An adaptation of multisystemic therapy (MST) was piloted to find out whether it would yield better outcomes than standard MST in families where the adolescent not only shows antisocial or delinquent behaviour, but also has an intellectual disability. METHOD: To establish the comparative effectiveness of MST-ID (n = 55) versus standard MST (n = 73), treatment outcomes were compared at the end of treatment and at 6-month follow-up. Pre-treatment differences were controlled for using the propensity score method. RESULTS: Multisystemic therapy-ID resulted in reduced police contact and reduced rule breaking behaviour that lasted up to 6 months post-treatment. Compared to standard MST, MST-ID more frequently resulted in improvements in parenting skills, family relations, social support, involvement with pro-social peers and sustained positive behavioural changes. At follow-up, more adolescents who had received MST-ID were still living at home. CONCLUSIONS: These results support further development of and research into the MST-ID adaptation.

Cognitive deficits in problematic drinkers with and without mild to borderline intellectual disability.

We examined cognitive deficits in problematic drinkers with and without mild to borderline intellectual disability (MBID). Problematic drinkers were expected to show a significantly lower estimated performance IQ (PIQ), but not a lower estimated verbal IQ (VIQ), compared to light drinkers. Participants ( N = 474) were divided into four groups based on IQ and severity of alcohol use-related problems. IQ was estimated using (a short form of) the Wechsler Adult Intelligence Scale third edition. Severity of alcohol use-related problems was assessed using the Alcohol Use Disorder Identification Test. Overall, there were no significant differences between light and problematic drinkers on estimated VIQ. Within the group without MBID, estimated PIQ was significantly lower. Estimated PIQ was not lower in problematic drinkers with MBID compared to light drinkers with MBID. The results are indicative of cognitive deficits in problematic drinkers without MBID. Screening for cognitive deficits with additional instruments is advised.

Eye movement desensitisation and reprocessing therapy for posttraumatic stress disorder in a child and an adolescent with mild to borderline intellectual disability: A multiple baseline across subjects study.

BACKGROUND: This study explored the effectiveness of eye movement desensitisation and reprocessing (EMDR) therapy for post-traumatic stress disorder (PTSD) in persons with mild to borderline intellectual disability (MBID) using a multiple baseline across subjects design. METHODS: One child and one adolescent with MBID, who met diagnostic criteria for PTSD according to a PTSD clinical interview (i.e., ADIS-C PTSD section), adapted and validated for this target group, were offered four sessions of EMDR. PTSD symptoms were measured before, during and after EMDR, and at six weeks follow-up. RESULTS: For both participants, number of PTSD symptoms decreased in response to treatment and both no longer met PTSD criteria at post-treatment. This result was maintained at 6-week follow-up. CONCLUSIONS: The results of this study add further support to the notion that EMDR can be an effective treatment for PTSD in children and adolescents with MBID. Replication of this study in larger samples and using a randomized controlled design is warranted.

The Role of Executive Control and Readiness to Change in Problematic Drinkers with Mild to Borderline Intellectual Disability.

BACKGROUND: Problematic alcohol use is associated with neuropsychological consequences, including cognitive biases. The goal of the study was to explore the moderating role of executive control and readiness to change on the relationship between alcohol use and cognitive biases in light and problematic drinkers with and without mild to borderline intellectual disability (MBID). METHOD: Participants (N = 112) performed the visual dot probe task to measure the strength of the cognitive biases. Executive control was measured using two computerised tasks for working memory capacity (Corsi block-tapping task) and inhibitory control (Go/No-go task). Readiness to change was measured using the Readiness to Change Questionnaire. RESULTS: No cognitive biases or executive dysfunctions were found in problematic drinkers. Working memory capacity and inhibitory control were impaired among individuals with MBID, irrespective of severity of alcohol use-related problems. Executive control and readiness to change did not moderate the relationship between alcohol use and cognitive biases. CONCLUSION: The results fail to support the dual-process models of addiction, but results need to be treated with caution given the problematic psychometric qualities of the visual dot probe task. Implementing a neurocognitive assessment and protocols in the treatment of substance use disorders seems premature.

TAPS-tool reveals severe under detection of substance use problems in patients with severe mental illness.

INTRODUCTION: Substance use disorders (SUD) and associated problems are highly prevalent but often undetected in patients with Severe Mental Illness (SMI). This study investigates the prevalence, under-detection, and variables associated with a high risk of SUD in a Dutch sample of adult outpatient SMI patients (N = 83). METHODS: Substance use (The Tobacco, Alcohol, Prescription medication, and other Substance use -TAPS-tool), quality of life (Manchester Short Assessment of Quality of Life-MANSA), general functioning (Health of the Nation Outcome Scale-HoNOS), DSM-5 classifications and patient characteristics (age, education, marital status) were assessed. Detection of SUD was determined by calculating % agreement of DSM-5 classification to TAPS outcome. A logistic regression analysis was performed to determine the association of patient characteristics, quality of life and general functioning to an increased risk of SUD as determined by the TAPS. RESULTS: Concerning prevalence, 89% of the patients used tobacco, above guideline-recommended daily limits of alcohol, illicit drugs or prescription medications for nonmedical purposes. Almost all smokers, half of the alcohol users and three-quarter of the patients that use marihuana or stimulant drugs had a high risk of SUD. All patients with high risk of SUD associated with alcohol, drugs or medications also had SUD associated with tobacco use. Concerning under detection less than half of the patients with a high risk of SUD according the TAPS had a SUD in their DSM-5 classification. Gender, partner, age and satisfaction about the relationship with family had a significant association with a high risk of SUD. CONCLUSIONS: Screening for addiction in an SMI sample with the TAPS-tool revealed a high prevalence of substance use and a high risk of SUD. TAPS outcomes compared to the clinically obtained DSM-5 classification revealed a high degree of under-detection of substance use problems. Smoking seems to pose a specific additional risk of addiction and deserves more attention in treatment to achieve greater health care benefits.

Putting the usability of wearable technology in forensic psychiatry to the test: a randomized crossover trial.

Introduction: Forensic psychiatric patients receive treatment to address their violent and aggressive behavior with the aim of facilitating their safe reintegration into society. On average, these treatments are effective, but the magnitude of effect sizes tends to be small, even when considering more recent advancements in digital mental health innovations. Recent research indicates that wearable technology has positive effects on the physical and mental health of the general population, and may thus also be of use in forensic psychiatry, both for patients and staff members. Several applications and use cases of wearable technology hold promise, particularly for patients with mild intellectual disability or borderline intellectual functioning, as these devices are thought to be user-friendly and provide continuous daily feedback. Method: In the current randomized crossover trial, we addressed several limitations from previous research and compared the (continuous) usability and acceptance of four selected wearable devices. Each device was worn for one week by staff members and patients, amounting to a total of four weeks. Two of the devices were general purpose fitness trackers, while the other two devices used custom made applications designed for bio-cueing and for providing insights into physiological reactivity to daily stressors and events. Results: Our findings indicated significant differences in usability, acceptance and continuous use between devices. The highest usability scores were obtained for the two fitness trackers (Fitbit and Garmin) compared to the two devices employing custom made applications (Sense-IT and E4 dashboard). The results showed similar outcomes for patients and staff members. Discussion: None of the devices obtained usability scores that would justify recommendation for future use considering international standards; a finding that raises concerns about the adaptation and uptake of wearable technology in the context of forensic psychiatry. We suggest that improvements in gamification and motivational aspects of wearable technology might be helpful to tackle several challenges related to wearable technology.

Dog-Assisted Therapy in Mental Health Care: A Qualitative Study on the Experiences of Patients with Intellectual Disabilities.

(1) Background: Dog-assisted therapy (DAT) is an experiential intervention to promote psychological, physical, and social functioning in children and adults. Only few studies have been conducted on DAT in adults with a mild intellectual disability or borderline intellectual functioning (MID-BIF). The purpose of this study was to explore the experiences of patients with MID-BIF undergoing DAT in a mental health care facility. (2) Method: Seven patients completed 13 to 15 sessions of DAT. Within two weeks of completing the program, they were interviewed using a semi-structured interview. The transcripts of the interviews were analysed using interpretational phenomenological analysis. In addition, the patients' relatives and the DAT therapist were interviewed, and a focus group discussion took place with each patient's treatment team. (3) Results: The patients' experiences were predominantly positive. Physical contact with the dog calmed them down. The dog offered them emotional support and helped them to make contact inside and outside the therapy and the setting where they lived. The patients also liked the fact that DAT focused on the dog rather than their problems, that the therapy was experiential and using a positive approach, and that, during the therapy, they did not feel like a patient but a human being. DAT is a promising therapy for patients with MID-BIF in mental health care facilities, but more research into its effectiveness and cost-effectiveness and ways to implement DAT in clinical practice is needed to make more definitive statements.
