"Opinions of researchers have varied widely with regard to the mental health of shamans, generally polarized into shamans being mentally ill or shamans being mentally healthy. One rigorously designed study (van Ommeren et al., 2004) found the shamans in one refugee group to be as mentally healthy or more mentally healthy than the other members of the community. Another study (Stephen & Suryani, 2000) of a different population of shamans found that, from the medical etic perspective, shamanic candidates qualified as mentally ill; yet, after training and initiation, the same individuals were deemed mentally healthy with psychotic features still evident. Moreover, the shamans had gained control of the psychosis, using it voluntarily in their shamanic practices."
"Importantly, because shamans appear to have a different mental illness-mental health trajectory and outcome, shamans may comprise a unique category of creativity that is different from most artists, eminent creators, clinical populations, and everyday creativity. This unique category might be due to established traditions of social support as set out in Figure 22."
