Etiology
Due to Psychological Factors Due to Combined Factors
Gender Identity Disorder
A. Strong & persistent cross-gender identification In children, manifested by 4 (or more) symptoms, including insistence that he or she is the opposite sex, preference for cross-sex roles and activities, and preference for opposite sex playmates. In adolescents & adults, symptoms include stated desire to be other sex, frequent passing as other sex, desire to live as other sex, or conviction that he or she has typical feeling of other sex
Gender Identity Disorder
B. Persistent discomfort with his or her sex or sense of inappropriateness in the gender role of that sex (often includes desire to be rid of primary and secondary sex characteristics) C. Not concurrent with a physical intersex condition D. Distress or impairment
G.I.D. vs. Homosexuality
Homosexuality is not a disorder (used to be, but not anymore) Gender Identity Disorder is independent of sexual orientation (e.g. a genetic male can want to be a woman and still be attracted to women) Big rate difference: G.I.D. approx 1/30,000 men, 1/100,000 women. Homosexuality: approx 3% population, gender ratio 2:1 male:female
G.I.D. vs. Transvestic Fetishism
In transvestites, there is usually no desire to switch gender (if there is, its diagnosed With Gender Dysphoria), but crossdressing done for sexual gratification or sense of well-being Transvestic Fetishism diagnosed only in heterosexual males
Paraphilias
Exhibitionism Fetishism Frotteurism Pedophilia Sexual Masochism Sexual Sadism Transvestic Fetishism Voyeurism Paraphilia NOS
Pedophilia
A. Over at least 6 months, recurrent, intense sexually arousing fantasies, sexual urges, or behaviors involving sexual activity with a prepubescent child or children (generally < 13 years old) B. The person has acted on these urges, or urges or fantasies cause distress or interpersonal difficulty C. The person is at least age 16 years and at least 5 years older than the children in Criterion A
Pedophilia
Specify if
Sexually attracted to males Sexually attracted to females Sexually attracted to both
Specify if
Limited to incest
Specify type
Exclusive type Nonexclusive type
Pedophilia
Not the same thing as child molestation
Pedophiles may not act on their urges Child molesters may not have pedophilic arousal patterns
Pedophilic arousal patterns are fairly strong predictors of recidivism
Pedophilia - Assessment
Phallometric assessment penile plethesmography (uses penile strain gage or measure of blood volume) Arousal assessed while viewing slides of nude children and adults (often includes audio narrative) Arousal to child slides compared to arousal to adult slides
Compulsive Sexual Behavior
Not a DSM diagnosis (maybe Sexual Disorder, N.O.S.) Includes elements of:
Sexual addiction Nymphomania/Satryriasis Hypersexuality
Can be paraphilic or nonparaphilic
Compulsive Sexual Behavior
Essentially, nonparaphilic CSB involves conventional and normative sexual behavior taken to a compulsive extreme. There is no clear category for this type of clinical syndrome - of obsessive and compulsive normophilic behavior.
CSB Proposed Criteria
Coleman, et al., 2000 A) Recurrent and intense normophilic sexually arousing fantasies, sexual urges, and behaviors which cause clinically significant distress in social, occupational, or other important areas of functioning.
CSB Criteria contd
B) Not due to a another medical condition, substance use disorder, attributable to another Axis I or II disorder, developmental disorder, and must take into account norms of gender, sexual orientation and sociocultural groups.
Types of Nonparaphilic CSB
Compulsive cruising and multiple partners Compulsive fixation on an unattainable partner Compulsive autoeroticism Compulsive multiple love relationships Compulsive sexuality in a relationship Possibly: Compulsive Use of Erotica Compulsive Use of the Internet for Sexual Purposes
CSB - Etiology
No agreement on this, thought of as: Variant of OCD Impulse Control Disorder Disorder of sexual desire Etc. Disagreement may be due to multiple types, possibly on a continuum
CSB-The Continuum Notion
Healthy
Problematic Impulsive
Clinical Syndrome Compulsive
Other Axis I Psychopathologies Axis II: Characteriolgical
CSB Associated Problems
Tend to have comorbid mood disorders (dysthymia or depression) or undiagnosed dysphoric mood A large number have problems with impulsivity, notably substance abuse and risky sexual behavior
What about Rape?
What motivates rape?
Most rapists dont have deviant sexual arousal
Plethesmography does not assess appetitive behavior frequency or intensity but does assess the objective of arousal Though deviant arousal plus high PCLR score best indicator of recidivism
Some rapists have comorbid paraphilias Is rape sexually motivated ?
From Kafka
Rape
From The Multidimensional Assessment of Sex and Aggression (MASA; Knight, 1994; 1999) Sexually coercive men were statistically significantly more likely to self-report more sexual fantasy and enacted sexual behavior in multivariate statistics (p= < 0.01) Differences were most robust in:
ideal desired frequency of sexual behavior TSO/week in past 6 months Lifetime maximum TSO/week
Knight , 2002, submitted for publication
What Makes a Rapist?
Sadistic Pervasively Angry
Vindictive
Abusive Hx CU Impulsivity Hypersexual
Predicting Sexual Recidivism
No one really does it well Plenty of instruments (MnSOST-R, VRAG, RRASOR. . .) None are quite as effective as they say they are Problems with predicting low base rate events
