Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Once pre-intervention surveys have been completed, participants (include children (11-17) and adults (18+) with ASD, caregivers of children with ASD. Children are required to participate with a caregiver) will be randomly allocated to the waitlisted control or intervention groups using a computer generated randomization procedure (i.e. randomizer.org). Following group allocation, intervention participants will be emailed a prompt to download the Smiling Mind app. The download will activate the Smiling Mind app’s daily reminder and activity alarms. Intervention participants will then select mindfulness meditations provided by the Smiling Mind app, based on their age group. Each participant will be asked to spend 10mins (Children with caregivers) or 20mins (Adults with ASD, individual caregivers) each day for 5 days taking part in the meditation exercises. Intervention fidelity is measured through in app monitoring of meditations. Post intervention survey's are issued immediately post-intervention and 1 month post-intervention.

Once the intervention is completed a qualitative survey involving a subsample of participants (up to 30 participants required to achieve data saturation across all groups - including adults with ASD and caregivers, with their children if possible), who have consented to be interviewed. Participants will be contacted through their nominated email address for an interview, as provided through the survey. Participant interviews will be semi-structured. The focus will be on questions relating to the smartphone app and, in particular, whether participants found the mindfulness intervention beneficial and what aspects were beneficial. Interviews will be conducted via telephone or video conferencing software where required.

Comparator / control treatment
The control group will be required to spend between 10-20mins each day in quiet interaction with their smartphone for 5 days. Caregivers participating with children will spend 10mins in quiet interaction, together, using their smartphone. Adults with ASD and caregivers will also spend their daily allocated 10-20mins quietly interacting with their smartphone for 5 days.

Efficacy
Statistical methods / analysis
Using power analysis the number of eligible participants will include caregivers of individuals with ASD and individuals with ASD (target sample size = ~52, Power = .8, alpha = .05, large effect size d = .8).

With participant consent, app usage data sourced from Smiling Mind will be used to assess treatment fidelity. This will include information relating to mindfulness meditations. Survey data will be analysed in R or SPSS software. Analyses will be performed on an intention-to treat basis with differences examined between intervention and control groups of participants using Reliable Change Indices (RCI). The comparison immediately post-intervention (i.e. 5 week survey) will be considered the primary outcome. Participant interviews will be semi-structured. The focus will be on questions relating to the smartphone app and, in particular, whether participants found the mindfulness intervention beneficial and what aspects were beneficial (See Appendix D for examples). Interviews will be conducted via telephone or video conferencing software where required.
