Virtual Mindfulness for Autistic Adults: A Randomized Controlled Trial

It is well recognized that autistic individuals experience high rates of mental health issues, but that needed mental health services are often inaccessible. There is some evidence to suggest that mindfulness-based therapies may help to reduce some of these challenges for autistic adults. While in person interventions may be helpful, there are also benefits to participating in virtually based interventions, particularly during the pandemic. Virtual groups have the added benefit of not requiring travel for people who have difficulties with travel because of anxiety or financial constraints. For some autistic individuals, virtual engagement can be preferred over in person interactions because of the flexibility that virtual interactions allow (camera on or off, communicating with text or speaking, being able to attend from home in a familiar and comfortable space).

In a prior CAMH led study, the investigators demonstrated that autism-informed adaptations to a standard mindfulness-based virtually delivered group intervention led to self-reported improvements in mindfulness, self-compassion, and distress, with changes maintained at three months follow-up. This prior study lacked a control group, however so it is not known whether the positive impacts reported were specific to the mindfulness-based intervention itself or to other factors. Building on this previous work, there is a need to study whether improvements are also evident when compared to individuals who do not take part in the intervention.

The purpose of this study is to test the effectiveness of a virtual group mindfulness intervention for autistic adults on their mental health and well-being, compared to a group who has not received the virtual group intervention. Specifically, the investigators will compare change across multiple indicators of mental health and well-being for participants, post-intervention, and at 15 weeks follow-up, to participants in a waitlist control group who have not yet received the intervention.

Study Design: Randomized controlled trial with waitlist control.

Hypotheses We expect that participants in the mindfulness-based intervention group will report improvements in self-reported distress (primary outcome), mindfulness, self-compassion, and sense of autistic belonging (secondary outcomes), relative to the waitlist control group, which will be maintained at 15 weeks follow-up.
