Peer-Reviewed Studies on the Benefits of Weighted Plushies, Blankets, and Vests for Anxiety, Depression, and Autism

Q: Do you have a list of peer-reviewed studies showing the benefits of weighted plushies, blankets and vests in individuals who suffer from anxiety, depression, stress, PTSD and autism?
A: Here's a list of peer-reviewed publications that suggest weighted stuffed animals and similar interventions are beneficial for individuals suffering from anxiety, depression, stress, PTSD, and autism. Note that while direct studies on weighted stuffed animals specifically may be limited, many studies on weighted blankets and similar sensory interventions can provide relevant insights:

While direct evidence on weighted stuffed animals specifically might be less common, these studies on weighted blankets, vests, and deep pressure therapy provide a strong foundation for understanding their potential benefits.
