Abstract
The rising prevalence of autism internationally has been accompanied by an increased appreciation of the poorer mental health experienced by people with this condition and also of their family care-givers. In particular, higher incidences of anxiety and depression are reported in high-income nations and these conditions are likely to be under-recognised and under-reported in lower-resourced regions or countries. Mainstream mental health services seem to be ill-equipped to respond adequately to the needs of autistic persons and their care-givers. This literature review of 29 recently published reviews covering nearly 1000 journal articles summarises the insights and strategies that have been shown to promote the mental health and emotional wellbeing of autistic persons. In particular, a focus on family-centred, community-based supports is recommended that aim to enhance social communication, extend social connections and promote an individual's self-esteem, self-determination and social motivation. These low-cost interventions are especially pertinent in low-resourced settings, but they can be used internationally to prevent mental illness and assist in the treatment of anxiety and depression in autistic persons and their family carers. The priority is to focus on primary-care responses with cross-sectoral working rather than investing in high-cost psychiatric provision.
