A study examining the relationship between alexithymia and challenging behaviour in adults with intellectual disability

Self-reported explanations for self-injury by people with intellectual disabilities: a systematic review of qualitative studies

Background

Emotional distress has received less attention as an explanatory factor for self-injury in people with intellectual disabilities, with research and practice primarily focusing on biobehavioural factors. This systematic review examines the self-reported explanations for self-injury by people with mild or moderate intellectual disabilities, and discusses how the findings contrast with those from self-reported studies of people within the general population who self-harm.

Methods

Five databases (PsychINFO, IBSS, CINAHL, Web of Science and Medline) were systematically searched to find qualitative, empirical research since 2000 about self-reported reasons for self-injury.

Results

Four studies were found which conducted research with people with intellectual disabilities. Three primary themes are discussed: relief from overwhelming emotions; trauma and loss; and difficulty in articulating emotions.

Conclusion

This review found a paucity of research asking people with intellectual disabilities about their own self-injury. However, the research available suggests that explanatory factors for self-injury typically reported in the general population should be considered for those with mild or moderate intellectual disabilities.

Assessment of Challenging Behavior Exhibited by People with Intellectual and Developmental Disabilities: A Systematic Review

The assessment of challenging behavior exhibited by people with intellectual and developmental disabilities is essential for the planning of prevention and intervention programs. This review aimed to identify and analyze the standardized instruments that exclusively focus on the assessment of challenging behavior. We identified and organized 141 articles into four categories: original instrument studies, validation studies, relational studies, and intervention studies. The results identified 24 instruments that generally show high-quality psychometric properties and other utilities beyond the observation of the presence of challenging behavior and diagnostic categorization. Age, level of adaptive behavior, disability, presence of autism spectrum disorder, and medication are some of the variables that were found to be possibly related to the occurrence of challenging behavior. Additionally, the results suggest that interventions focused on supporting positive behavior or providing training on behavior to professionals and caregivers significantly reduced the occurrence of these behaviors. Instruments that help us to understand and measure the challenging behavior exhibited by people with intellectual and developmental disabilities are essential for the design of effective evaluation and intervention protocols.

Behavioural, psychiatric and psychosocial factors associated with aggressive behaviour in adults with intellectual disabilities: A systematic review and narrative analysis

Background

Aggressive behaviour is prevalent in people with intellectual disabilities. To understand the aetiology, it is important to recognize factors associated with the behaviour.

Method

A systematic review was conducted and included studies published between January 2002 and April 2017 on the association of behavioural, psychiatric and psychosocial factors with aggressive behaviour in adults with intellectual disabilities.

Results

Thirty‐eight studies were included that presented associations with 11 behavioural, psychiatric and psychosocial factors. Conflicting evidence was found on the association of these factors with aggressive behaviour.

Conclusions

The aetiology of aggressive behaviour is specific for a certain person in a certain context and may be multifactorial. Additional research is required to identify contributing factors, to understand causal relationships and to increase knowledge on possible interaction effects of different factors.
