“…However, the most commonly used treatment for anger are cognitive behavioural therapy and mindfulness (see for example, Onwubiko, 2022 ). For a recent review on the use of cognitive behavioral therapy and mindfulness for the treatment of anger and aggression, see Didden et al ( 2019 ). However, the Didden et al ( 2019 ) review study did not compare which treatment, cognitive behavioural therapy or mindfulness, is more effective at treating anger and aggression.…”

“…Mindfulness training techniques were also found to decrease amygdala activity (Murakami et al, 2015 ), explaining perhaps how mindfulness is effective at treating anger. Mindfulness training includes training clients to disengage their attention from anger-related triggers (Didden et al, 2019 ). Several other studies have shown that mindfulness training successfully reduced aggression in individuals with intellectual disabilities (Singh et al, 2013 ), although it is not clear if these findings are generalizable to other populations.…”

Anger and aggression have large impact on people’s safety and the society at large. In order to provide an intervention to minimise aggressive behaviours, it is important to understand the neural and cognitive aspects of anger and aggression. In this systematic review, we investigate the cognitive and neural aspects of anger-related processes, including anger-related behaviours and anger reduction. Using this information, we then review prior existing methods on the treatment of anger-related disorders as well as anger management, including mindfulness and cognitive behavioural therapy. At the cognitive level, our review that anger is associated with excessive attention to anger-related stimuli and impulsivity. At the neural level, anger is associated with abnormal functioning of the amygdala and ventromedial prefrontal cortex. In conclusions, based on cognitive and neural studies, we here argue that mindfulness based cognitive behavioural therapy may be better at reducing anger and aggression than other behavioural treatments, such as cognitive behavioural therapy or mindfulness alone. We provide key information on future research work and best ways to manage anger and reduce aggression. Importantly, future research should investigate how anger related behaviours is acquired and how stress impacts the development of anger.

“…The subscale Self‐management skills contains three items that address coping skills. Copings skills of clients have been considered important in the treatment of externalising problems (Didden et al, 2019). However, for the other items in this subscale ( Thoughtlessness and Maintaining meaningful daytime activities ) more research is needed to show their added value.…”

IntroductionThis study investigated the reliability and validity of the dynamic risk outcome scales—short version (DROS‐SV). This instrument is developed to monitor treatment progress using dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning and behavioural and/or mental health problems.MethodData were collected from 264 clients who received Flexible Assertive Community Treatment (FACT), a form of intensive outpatient treatment.ResultsA principal component analysis showed that there were six components explaining 73.9% of the variance. Furthermore, the DROS‐SV showed good internal consistency of its subscales and total score (α > 0.78). Correlating the DROS‐SV with the Historical and Clinical subscales of the Historical, Clinical and Future—30 indicated convergent and divergent validity.DiscussionThe DROS‐SV has good psychometric properties for measuring dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning in FACT teams.

“…Prevalence rates range from 10% to more than 45% depending on the definitions of aggressive behaviour, the sub‐population studied and the measurement methods used (Bowring et al, 2019 ; Didden et al, 2016 ; Drieschner et al, 2013 ). Much can be done to reduce aggression, for example through the use of anger management interventions, behavioural therapies, contextual approaches, sedatives, and off‐label antipsychotics (Didden et al, 2019 ; Lloyd & Kennedy, 2014 ). However, other evidence‐based and safe treatment options remain necessary (Didden et al, 2016 ; Scheifes, 2015 ).…”

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.
