In U.S. MH providers are required to adults. Check with your state licensing board for specific U.S. information. Other countries may or may not have similar requirements. In some states, a MH practitioners may have pd or volunteer Peer Providers. A “peer” is defined a person from the same or quite similar background as those receiving therapy, i.e. Veteran serving vets, persons with Substance Use background serving those with active SA issues. I have supervised many Peer Provider, but they were all adults. If a workshop were held or group therapy were provided, Peer Providers may assist. Again, your best bet is contacting your licensing bureau.
