Objective: Hypnosis is an adjunctive, noninvasive treatment
with few side effects that can be useful in the management of chronic
pain. However, it has fallen into disfavor in recent years and is often
perceived by physicians as simple charlatanism. We evaluated the efficacy
of this treatment as used clinically in a large, mostly rural, pain
management center.
Methods: We conducted a chart review of 300 pain patients
from the Pain Treatment Center of the Bluegrass who had undergone hypnosis
for their pain concerns. A chart audit tool was developed consisting of
basic demographics, pre- and posthypnosis pain ratings, a rating of
relaxation achieved posthypnosis, and scores on the Beck Depression
Inventory, Perceived Disability Scale, and the Pain Anxiety Symptom
Scale.
Results: The sample consisted of 79 men (26.3%) and 221 women
(73.7%) with a mean age of 46.3 years (SD = 9.9, range =
19–78). Pain levels recorded pre- and posthypnosis revealed
significant improvement as a result of the intervention (mean difference =
2.5, t(1,298) = 25.9, p < .001). Patients reported an
average of 49.8% improvement in relaxation level posthypnosis (SD
= 24.2%) and had a mean score of 19.0 on the Beck Depression Inventory
(SD = 9.9), indicating moderate levels of depression. Also,
patients saw themselves as severely disabled regarding their ability to
engage in physical (8.3/10) or job-related (7.7/10) activities.
Attempts to identify predictors of hypnosis success were not fruitful with
one exception. “Poor” responders to hypnosis reported greater
levels of perceived dysfunction in their sexual functioning compared to
the “good” responders, F(1,187) = 7.2, p
< .01.
Significance of results: Hypnosis appears to be a viable
adjunct for pain management patients, including those from rural and
relatively disadvantaged backgrounds. Prospective trials are needed to
examine the utility of this modality in end-of-life and palliative care
patients.
