Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention Group (Purrble)
Participants in this group will be provided with the Purrble device, while waitlisted for eating disorder treatment.
Purrble
The intervention takes the form of an interactive plush toy, which was co-designed with children to support in-the-moment soothing. The device is framed as an anxious creature, in need of care and attention when it feels distressed. This distress is indicated by a simulated heartbeat using embedded electronics to produce vibration patterns of i) frantic and anxious, to ii) slow, steady and relaxed. When held, the device emits a frantic heartbeat which can be slowed by stroking movements registered by embedded sensors. Once the device has been "soothed" for long enough, the heartbeat transitions into a purring vibration indicating a relaxed state. This transition can be achieved in under 1 minute but is dependent on the device-human interaction.
Control Group
The control condition will be waitlist as usual. Participants in this arm will not receive the Purrble intervention and will serve as a reference group for comparison.
No interventions assigned to this group
