Affective issues of adult male sex offenders were examined by employing Eye
Movement Desensitization and Reprocessing (EMDR), a therapeutic intervention that
assists in rapidly resolving troubling thoughts, emotions, and physical sensations.
Incorporating EMDR into the current cognitive/behavioral/relapse prevention (RP)
treatment model for sex offender treatment opens the possibility of reducing the reoffense
rate by addressing offenders’ own emotional wounding from early trauma and
victimization. The experimental group of offenders (n = 27) received a pretest, three
EMDR sessions, and a posttest over an average time o f 3.8 months. The Multiphasic Sex
Inventory (MSI) was the measure used for this research. The three scales on that test
designed to measure for thinking errors were the Cognitive Distortion and Immaturity
(CDI) Scale; the Justification (Ju) Scale; and the Treatment Attitudes (TA) Scale.
Archived pretest/posttest scores of randomly selected and anonymous adult male sex
offenders comprised the control group (n = 27). This group was tested on the MSI and
MSI 2 before entering Module 4 and after finishing Module 5, representing 22.5 months
of treatment pretest/posttest. All control and experimental group subjects took part in a
mandated cognitive/ behavioral/relapse prevention (RP) program. The independent twosample t test was used to compare two means using the rate o f change between the
experimental and control group. EMDR treatment was found to be no better than RP
treatment in addiressing issues on the CDI and TA scales. A statistically significant
reduction was found in justifications for offender behavior in the experimental group on
the Ju scale (p-value = 0.008), suggesting further research is needed on the effect o f
offender victimization issues on reducing justifications for victimizing others.
