Factors affecting the relationship between adaptive behavior and challenging behaviors in individuals with intellectual disability and co-occurring disorders

Immersive virtual reality is more effective than non-immersive devices for developing real-world skills in people with intellectual disability

BACKGROUND

People with intellectual disability (ID) demonstrate persistent challenges around developing life skills. Immersive virtual reality (IVR) is gaining interest as a tool for training life skills as it enables individuals to engage in hands-on learning in a safe, controlled and repeatable environment. However, there are concerns about the potential drawbacks of IVR, such as cybersickness and practical challenges with using the equipment, which may hinder its widespread adoption in educational settings. The current study aimed to compare the effectiveness of training in IVR and a non-immersive virtual environment for improving real-world skills in people with ID.

METHODS

In the present study, 36 adults (16 female, 20 male) with ID were recruited from a disability organisation. Participants completed a real-world assessment of waste management skills before and after training in either the IVR or non-immersive group.

RESULTS

Consistent with our hypotheses, the IVR group scored significantly higher in the real-world assessment after virtual training (d = 1), and at the 1-week follow-up (d = 1.12), compared with the non-immersive group. Further analyses showed that the IVR group, but not the non-immersive group, significantly improved performance in the real-world assessment across timepoints.

CONCLUSIONS

The findings indicate that IVR was more effective for improving and retaining real-world waste management skills. This study supports IVR as a viable tool for professionals and caregivers to develop skills for independent living among people with ID.

Challenging behaviors in adults with autism spectrum disorder and intellectual disability: A differential analysis from a transdiagnostic approach

This study aimed at analyzing the differences in challenging behaviors between adults with intellectual disability and ASD and those who only had intellectual disability, as well as to explore associations between transdiagnostic and clinical variables to these differences. Therapists and educators of 163 adults with intellectual disability (83 with additional ASD diagnosis) completed the test battery. Mean difference analysis and univariate analyses of covariance were performed to determine the impact of clinical variables and transdiagnostic variables on the frequency and severity of challenging behaviors. Results showed that adults with ASD and intellectual disability presented higher frequency and severity of these behaviors. A significant effect of the diagnosis of ASD on the frequency and severity of self-injuries and stereotypies was found. Also, some transdiagnostic variables influencing the presence of these behaviors were highlighted. These factors should be considered when planning and designing interventions for behavioral problems in this population.

Improving real-world skills in people with intellectual disabilities: an immersive virtual reality intervention

Virtual reality (VR) is a promising tool for training life skills in people with intellectual disabilities. However, there is a lack of evidence surrounding the implementation, suitability, and effectiveness of VR training in this population. The present study investigated the effectiveness of VR training for people with intellectual disabilities by assessing (1) their ability to complete basic tasks in VR, (2) real-world transfer and skill generalisation, and (3) the individual characteristics of participants able to benefit from VR training. Thirty-two participants with an intellectual disability of varying severity completed a waste management training intervention in VR that involved sorting 18 items into three bins. Real-world performance was measured at pre-test, post-test, and delayed time points. The number of VR training sessions varied as training ceased when participants met the learning target (≈ 90% correct). A survival analysis assessed training success probability as a function of the number of training sessions with participants split by their level of adaptive functioning (as measured on the Adaptive Behaviour Assessment System Third Edition). The learning target was met by 19 participants (59.4%) within ten sessions (Mdn = 8.5, IQR 4-10). Real-world performance significantly improved from pre- to post-test and pre- to delayed test. There was no significant difference from post- to delayed test. Further, there was a significant positive relationship between adaptive functioning and change in the real-world assessment from the pre-test to the post- and delayed tests. VR facilitated the learning of most participants, which led to demonstrations of real-world transfer and skill generalisation. The present study identified a relationship between adaptive functioning and success in VR training. The survival curve may assist in planning future studies and training programs.

Preferred outcome measures in treatments for challenging behaviour in individuals with intellectual disabilities: Results of an inclusive Delphi method

BACKGROUND

Interventions for challenging behaviours in individuals with intellectual disabilities benefit from outcome monitoring that takes clients' preferences into account. We determined clients' and representatives' preferred outcome domains and measures to secure their involvement in treatment decisions for challenging behaviours.

METHOD

We used an inclusive Delphi method. A focus group of individuals with mild intellectual disabilities and representatives of those with moderate and severe intellectual disabilities prepared the first round by assisting us in collecting possible outcomes. Panels of individuals with intellectual disabilities and representatives were composed to achieve consensus on instruments for preferred outcome domains.

RESULTS

Preferred outcome domains were behaviour, side-effects of psychotropic drugs, quality of life, daily functioning, caregiver burden and family quality of life. Corresponding outcome measures included self-report, interview and proxy-scales, including spoken versions.

CONCLUSION

Including the preferred domains on outcomes of interventions for challenging behaviours is recommended. Research on corresponding outcome measures is necessary.

Adaptive Behavior in Slovak Children with Intellectual Disability in Institutional Care

This study aimed to analyze the adaptive skills of children with intellectual disabilities in institutional care. We focused on communication, socialization, daily living skills and their relationship with risk factors, and institutional care. Our sample included 197 children aged 5−18 years (M = 12.8, SD = 2.97), 50% boys, with IQ < 85 placed in different types and lengths of stay in institutional care. There were 17% that presented with borderline intellectual functioning (IQ 84−87) and 83% that had intellect disabilities. Adaptive behavior (AB) was assessed by Vineland Adaptive Behavior Scale (VABS-3). The BIF and Mild ID groups did not differ in Socialization. The profile of adaptive behavior for BIF and Mild ID was Daily Living Skills > Communication > Socialization, and for Moderate and Severe ID, Socialization > Daily Living Skills > Communication. Longer institutional care was associated with lower competencies in AB. Gender differences were found, females overperformed males in Socialization, Daily Living Skills, and ABC score. Levels of ID, gender, length of stay in institutional care, and neonatal difficulties were significant predictors in the model which explain the 63% variance of AB. The practical implications of the results are discussed related to the assessment of ID, prevention, and care for institutionalized children.

Pharmacotherapy of Disruptive Behaviors in Children with Intellectual Disabilities

Disruptive behaviors are a class of predominantly externalizing behaviors that include physical aggression, property destruction, temper outbursts, verbal aggression, and some forms of self-injurious behaviors. Externalizing behaviors are also major components of disruptive, impulse-control and conduct disorders, disruptive mood dysregulation disorder, trauma-related and stressor-related disorders, intermittent explosive disorder, personality disorders, and other neuropsychiatric and neurodevelopmental disorders. Disruptive behaviors and associated disorders are among the most frequent reasons for child behavioral health referrals and are the most common reason for referrals among children with intellectual disabilities. The focus of this paper is on the adjunctive role of integrated psychopharmacological treatment in the management of children with disruptive behaviors and co-occurring intellectual disabilities. The decision-making process for adding pharmacotherapy to a comprehensive treatment plan incorporates not only a working knowledge of basic behavioral neurobiology of disruptive behaviors but also an understanding of the strengths and weaknesses of various pharmacotherapies. Importantly, there is little evidence to support the use of psychopharmacologic agents in managing difficult behaviors in children with intellectual disabilities, but with that said, risperidone has the strongest evidence base for its use.

Intellectual Disability Profiles, Quality of Life and Maladaptive Behavior in Deaf Adults: An Exploratory Study

Individuals who are prelingually deaf and have intellectual disabilities experience great challenges in their language, cognitive and social development, leading to heterogeneous profiles of intellectual and adaptive functioning. The present study describes these profiles, paying particular attention to domain discrepancies, and explores their associations with quality of life and maladaptive behavior. Twenty-nine adults with prelingual deafness (31% female) and mild intellectual functioning deficits (mean IQ = 67.3, SD = 6.5) were administered the Vineland Adaptive Behavior Scales-II (VABS-II) and an adapted sign language version of a quality of life scale (EUROHIS-QOL 8). Intellectual disability domain discrepancies were characterized as at least one standard deviation difference between the social domain and IQ and the practical domain and IQ, and a significant difference, according to the VABS-II manual, between the social and practical domains. Domain discrepancies were found between intellectual functioning and both the practical (58.6%) and social domain (65.5%). A discrepancy between intellectual and social functioning was significantly associated with a higher level of internalizing maladaptive behavior (T = 1.89, p < 0.05). The heterogeneous profiles highlight the importance of comprehensive assessments for adequate service provision.

Italian Diagnostic Adaptive Behavior Scale: Reliability and diagnostic accuracy compared with the Vineland-II

BACKGROUND

The Diagnostic Adaptive Behavior Scale (DABS) is a short scale with excellent properties to assess the conceptual, social, and practical adaptive behavior domains for the diagnosis of intellectual disability (ID) in individuals aged 4-21 years.

AIMS

Investigate the test-retest and inter-respondent reliability of the Italian adaptation of the DABS, verify its diagnostic accuracy in identifying individuals with ID and excluding individuals with typical development (TD), and compare its psychometric properties to those of the Vineland-II.

METHODS

Test-retest reliability: The same respondent completed the Italian DABS for the same assessed person at two separate times (n = 71). Inter-respondent reliability: Two respondents for the same assessed person completed the Italian DABS independently (n = 57). Diagnostic accuracy: The same respondent completed the Italian DABS and Vineland-II for the same assessed person (n = 378; 50 % ID, 50 % TD).

RESULTS

Italian DABS test-retest and inter-respondent correlation coefficients were excellent. Italian DABS sensitivity was 86 % and specificity was 99 %, Italian DABS Areas Under the ROC Curves were excellent (or good, practical skill domain), and comparable to the results reported for the Vineland-II.

CONCLUSIONS

The Italian DABS is an excellent measure to evaluate the adaptive behavior for ID diagnosis; it is comparable to the Vineland-II but being shorter, the Italian DABS requires less time to administer.

Behavioral and emotional problems of toddlers with autism spectrum disorder: Effects of parents' sociocultural level and individual factors

BACKGROUND

Toddlers with autism spectrum disorder (ASD) show higher prevalence and severity of Behavioral and Emotional Problems (BEP) than their peers without ASD.

AIMS

Investigating the effects of parental factors, i.e., mothers' and fathers' age and Sociocultural Level (Socioeconomic Status, Cultural Capital, and Social Capital), and individual factors, i.e., toddles' age, birth order, general development, autism symptom severity, and adaptive behavior, on the expression of BEP in toddlers with ASD.

METHODS

Participants were 148 toddlers with ASD (aged 18-37 months) and both their parents. BEP were measured with the Child Behavior Checklist 1½-5 (CBCL) Syndrome and Pervasive developmental problems (PDD) DSM-oriented scales, general development with the Griffiths Mental Development Scales (GMDS), autism symptom severity with the Autism Diagnostic Observation Schedule-2 (ADOS-2), and adaptive behavior with the Vineland-II Adaptive behavior composite.

RESULTS

Vineland-IIAdaptive behavior composite was negatively associated with the majority of the CBCL scales. In contrast, the ADOS-2 Restrictive and repetitive behavior was negatively and the ADOS-2 Social affect, toddlers' age, and birth order were positively associated with only a few of the CBCL scales (e.g., PDD). GMDS scores were not associated with any CBCL scales. Mothers' age and fathers' Cultural Capital and Social Capital dimensions were negatively associated with specific CBCL scales, even when considered in addition to individuals' factors.

CONCLUSIONS

Individual and parental factors simultaneously affect the expression of BEP and should be considered for clinical decisions.

Challenging behaviors among students with severe developmental disabilities in Saudi Arabia: Impact of socio-demographic differences

This study aimed to explore the prevalence of challenging behaviors (CBs) associated with students with severe developmental disabilities (SDDs) as rated by their teachers. The study also attempted to examine whether the occurrence and intensity of CBs might depend on certain socio-demographic variables. Data was collected using a questionnaire to rate the prevalence of CBs in 687 students with SDDs. Results indicate that social problems, stereotypical behaviors, and disobedient behaviors were estimated to be the most prevalent of CBs among such students. Positive correlations were confirmed between the type of disability, gender, age, school grade, educational placement, and the prevalence of CBs among students with SDDs. Implications for educational practice and recommendations for future research are discussed.
