Brief Summary

This research concerns the evaluation of the maintenance of the efficiency and incidence of adverse effects of pharmacological treatments in sex offenders with paraphilia.

Despite the increasing use of pharmacological treatments in these indications, there are few data to indicate which sex offender populations benefit from which pharmacological treatments and which adverse events are observed, particularly with anti-androgens or antidepressant treatments that are widely used in these subjects. A recent Cochrane study showed that psychodynamic treatment is less effective in terms of sexual delinquency compared to probation alone and has not shown significant efficacy of cognitive behavioral therapy (CBT) compared to the lack of treatment, except for a study in which anti-androgen therapy was associated with CBT. Another recent study concluded that the tolerance, even of anti-androgenic drugs, was uncertain, as all studies were small and of limited duration, and new research is needed in the future. Further research demonstrating the efficacy of SSRIs in the treatment of paraphilic disorders is still needed and long-term studies are lacking. Their use for this indication is still off label.

As far as we know, this cohort should be the largest population of paraphilic sex offenders studied for the longest time to date in a field where research is insufficient. This large sample receiving routine care and followed for 3 years should allow to analyse the maintenance of the effectiveness of the pharmacological treatments received (SSRIs or anti-androgens), and their tolerance. In addition, this analysis of clinical practices should be crucial to improve the knowledge of the indications for these treatments, which could possibly be reviewed with respect to their effectiveness and tolerance, especially in the most serious cases of paraphilic sex offenders.

Detailed Description

This research uses a "naturalistic" follow-up method (over 3 years). The main objectives focuses on two main issues that are important in clinical practice: (1) the tolerance of anti-androgenic treatments traditionally used for many years in young sexual offenders with severe paraphilias (2) the maintenance of the efficiency of SSRIs not yet approved for this indication (despite their current use in the treatment of minor paraphilic disorders).

The paraphilic sex offender population are divided into three groups: those receiving SSRIs, those receiving anti-androgens (either GnRH agonists or CPA) and those receiving no pharmacological treatment.

Primary Outcome Measures
NameTimeMethod
Sexual desire and activity intensity scaleChange from inclusion at 36 months

ISRS Group and no pharmacological treatment group : Treatment efficiency : Sexual desire intensity and scale to measure deviant and non deviant sexual behavior symptoms. (Lickert's scale, scale range : 0 to 7)

Incidence of adverse events36 months

Anti-Androgen Group and no pharmacological treatment group : Report of any adverse event: the type, frequency, time of occurrence of adverse events

Secondary Outcome Measures
NameTimeMethod
Relapse rateEvery 3 months up to 36 months

Must stay rare event (low expected number, sexual offense risk evaluated in literature around 10%when the treatment is controlled regularly, the relapses are statistically analysed if the numbers is sufficient, but it can not be a principal assessment because of their rarity).

Sexual desire intensity scaleEvery 3 months up to 36 months

Anti-Androgen Group : Treatment efficiency : Sexual desire intensity and scale to measure deviant and non deviant sexual behavior symptoms

Incidence of adverse eventsEvery 3 months up to 36 months

ISRS Group: Report of any adverse event: the type, frequency, time of occurrence of adverse events

Clinical factorsEvery 3 months up to 36 months

All groups : Maintenance of efficacy and incidence of side effects will be analysed taking into account clinical factors listed above.

Psychological factorsEvery 3 months up to 36 months

All groups : Maintenance of efficacy and incidence of side effects will be analysed taking into account psychological factors listed above.

Demographic factorsEvery 3 months up to 36 months

All groups : Maintenance of efficacy and incidence of side effects will be analysed taking into account demographic factors listed above.
