Numerous anecdotal reports and textbooks from distinguished mental hea
lth practitioners have accorded to clinical hypnosis a prominent role
in the successful psychotherapeutic treatment of Dissociative Identity
Disorder (DID). This ideographic inquiry of one such treatment offers
empirical support for the instrumental effects of clinical hypnosis w
ith a highly hypnotizable patient who alleged intermittent sexual abus
e during the 2-5 age range. Multiple pre-and post-intervention measure
s, plus treatment trajectory monitoring and explication, demonstrate h
ow hypnosis methodology contributed to a rapid recovery from DID. Futu
re research is called for to further elucidate the therapeutic benefit
s of clinical hypnosis for DID patients having different levels of hyp
notizability and treatment responsiveness.
