LAY ABSTRACT: Nearly three out of four autistic people experience mental health problems such as stress, anxiety or depression. The research already done does not guide us on how best to prevent or treat mental health problems for autistic people. Our aim was to look at the benefits and harms of different interventions on mental health outcomes in autistic people. We searched all the published randomised controlled trials (RCTs) about interventions for mental health conditions in autistic people until 17 October 2020. We also searched for RCTs that were not published in peer-reviewed journals. These were obtained from registers of clinical trials online. We then combined the information from all these trials using advanced statistical methods to analyse how good the interventions are. Seventy-one studies (3630 participants) provided information for this research. The studies reported how participants were responding to the intervention for only a short period of time. The trials did not report which interventions worked for people with intellectual disability. In people without intellectual disability, some forms of cognitive behavioural therapy and mindfulness therapy may be helpful. However, further research is necessary. Many trials used medications to target core features of autism rather than targeting mental health conditions, but these medications did not help autistic people. Until we have more evidence, treatment of mental health conditions in autistic people should follow the evidence available for non-autistic people. We plan to widely disseminate the findings to healthcare professionals through medical journals and conferences and contact other groups representing autistic people.
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder affecting multiple developmental domains including social communication, behavioral-affective, sensorimotor, and cognitive systems. There is growing evidence for the use of holistic, whole-body, Creative Movement Therapies (CMT) such as music, dance, yoga, theater, and martial arts in addressing the multisystem impairments in ASD. We conducted a comprehensive quantitative and qualitative review of the evidence to date on the effects of CMT on multiple systems in individuals with ASD. The strongest evidence, both in terms of quantity and quality, exists for music and martial arts-based interventions followed by yoga and theater, with very limited research on dance-based approaches. Our review of 72 studies (N = 1,939 participants) across participants with ASD ranging from 3 to 65 years of age suggests that at present there is consistent evidence from high quality studies for small-to-large sized improvements in social communication skills following music and martial arts therapies and medium-to-large improvements in motor and cognitive skills following yoga and martial arts training, with insufficient evidence to date for gains in affective, sensory, and functional participation domains following CMT. Although promising, our review serves as a call for more rigorous high-quality research to assess the multisystem effects of CMT in ASD. Based on the existing literature, we discuss implications of our findings for autism researchers and also provide evidence-based guidelines for clinicians to incorporate CMT approaches in their plan of care for individuals with ASD.
PLAIN LANGUAGE SUMMARY: Cognitive behavioural therapy for anxiety in school-aged children with autism spectrum disorder can reduce anxiety Cognitive behavioural therapy interventions to reduce the level of anxiety in students with autism spectrum disorder are moderately effective. What is this review about? Anxiety is a common problem in school-aged children with autism spectrum disorder (ASD). Cognitive behavioural therapy (CBT) and other psychosocial interventions have been developed as alternatives to pharmacological intervention to treat anxiety in students with ASD. What is the aim of this review? This Campbell systematic review examines the effects of interventions for reducing anxiety in school-aged children with autism spectrum disorder, compared to treatment-as-usual. The review summarises evidence from 24 studies using an experimental or quasi-experimental design. What studies are included? Twenty-four studies, involving 931 school-aged children with ASD (without co-occurring intellectual disability) and clinical anxiety, are summarised in this review. The studies were experimental or quasi-experimental control-treatment trials, deemed to be of sufficient methodological quality and with reduced risk of bias. Studies spanned the period 2005 to 2018 and were mostly carried out in Australia, the UK and the USA. Examined interventions ranged across clinical, school-based, or home-based settings, with group or individual treatment formats. Twenty-two of the studies used a CBT intervention. One study used peer-mediated theatre therapy and one study examined the benefits of Thai traditional massage for reducing anxiety. Most interventions involved parents/caregivers and were conducted face-to-face. What are the main findings of this review? Overall, the effects of interventions on anxiety show a statistically significant moderate to high effect, compared to waitlist and treatment-as-usual control conditions at post-treatment. However, effects differ depending on who reports on the student’s anxiety. Clinician reports indicate a very high statistically significant effect, parent reports indicate a high significant effect, and self-reports indicate only a moderate significant effect on the reduction of anxiety in students with ASD. There are larger effects for treatments that involve parents than for student-only interventions. Effects are also larger for individual one-on-one interventions compared to treatments delivered in a group with peers. There are several risk-of-bias issues in most studies included in the review, mainly due to the unavoidable limitation that participants cannot be blinded to the treatment group, which may upwardly bias the estimated effects. There are also limitations in the description of randomisation in a third of the studies, so findings should be treated with caution. What do the findings of this review mean? The findings provide evidence in support of interventions, particularly CBTs, designed to reduce anxiety symptoms in school-aged children with ASD. These findings accord with and build upon the findings of previous systematic reviews into the effectiveness of interventions to reduce anxiety in children and youth with ASD. However, because of the risk of bias in current findings, it would be useful to have further studies with larger sample sizes and to reduce potential biases where possible. How up-to-date is this review? The review authors searched for studies up to the end of 2018.
