Imagery Technology: Effects on a Chronic Pain Population

The effects of a computer program (Health Imagery Technology Systems, HITS) designed to promote attitude and cognitive changes through elicitation of evoked response potentials were evaluated with chronic pain patients. A treatment and control group were used for comparison (52 patients, 22 females, 32 males, mean ages 47). Wechsler Adult Intelligence Scale-Revised subtests, a Semantic Differential scale, the Health Attribution Test, an imagery protocol, the McCoy-Lawlis Pain Drawing, and the Zung Depression scale were used at admission and discharge to measure change. A pre- post-mood thermometer was used with the treatment group. The hypotheses that the treatment group would show significant changes on these measures were tested with a two group repeated measures analysis of variance design. No significant changes were noted for either group on the intellectual measures, on health attitudes, or reports of pain. The similarities subscale showed significant within group variance (F = 5.46, p < .023). One bipolar adjective pair indicated significant differences (F = 4.79, p < .035), possibly a result of chance. One of seven imagery measures suggested a significant improvement in strength of imagery for the treatment group (F = 18.2, p < .00008). Both groups showed significantly improved imagery of body defenses (F = 4.58, £ < .037) and significantly reduced depression scores (F = 15.93, p < .000021). A mood thermometer was measured for the treatment group alone and five situational mood changes were significant in predicted directions. Post hoc discriminant analysis showed significant differences only on one adjective pair (F = 9.75, p < .0029). No combination of variables added to the prediction of group membership. Overall, the effects of the HITS program did not seem strong enough to indicate its value as a treatment modality in chronic pain populations beyond current treatment. It did indicate some significant situational mood effects in positive directions.
