Group psychotherapy is the most widely utilized treatment modality for convicted
sex offenders, and the therapeutic alliance is considered a fundamental concept in
virtually all applications of psychotherapy. However, empirical examination of how the
therapeutic alliance impacts upon treatment effectiveness for sex offenders has been
neglected. In a prospective design, a sample of 95 consecutive admissions to an inpatient
treatment program for convicted adult male sex offenders was studied with regard to their
experience of the therapeutic alliance with treatment staff, with their copatients, and with
the overall treatment program. Patients of the Phoenix Program (Alberta Hospital
Edmonton) rated their sense of alliance at monthly intervals. The therapists who worked
with them (n = 21) also completed monthly evaluations of their own emotional responses
toward these same patients. Pre- to post-treatment comparisons on personality tests,
interpersonal distress, and interpersonal functioning showed a number of statistically
significant changes consistent with treatment goals. Patients’ self-report over time in
treatment showed a gradual, consistent increase of large effect size on all three alliance
targets. Sex offenders in this sample were able to experience positive alliance with
therapists and peers and the sense of alliance was shown to grow stronger over time. Staff
ratings revealed that positive and negative affect increased as patients’ time in treatment
increased. Significant associations between patient-rated alliance and outcome were
found to be positive and in desired directions. The growth rate in alliance toward
therapists was positively and significantly associated with the growth rate of “conflict
within oneself” among female therapists. Male therapists also reported significant growth
in “conflict within oneself” but this was independent of patient-rated alliance growth rates. Thus, female therapists experienced heightened affect in the face of greater patient
alliance, while male therapists also experienced heightened affect but for reasons
unrelated to patient alliance. There was virtually no reduction in negative affect toward
patients despite moderate increases in positive affect toward patients. This study
represents an important endorsement of a treatment model that seeks to improve general
adjustment and ameliorate risk factors associated with recidivism, via positive changes in interpersonal relationships
