In the mid-1900s, the popularity of psychoanalysis in the United States was evident in the first two editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM) from the American Psychiatric Association (APA, Diagnostic and statistical manual: Mental disorders, 1952; Diagnostic and statistical manual of mental disorders, 1968); these editions were inspired by mostly psychodynamic ideas and etiological theories as it related to sexual deviation. Specifically, the original DSM (APA, Diagnostic and statistical manual: Mental disorders, 1952) had minimal information regarding sexual deviations as they were identified as “sociopathic personality disturbances”. The DSM-II (APA, Diagnostic and statistical manual of mental disorders, 1968) exhibited increased specificity of sexual deviation by categorizing sexual interests when they were directed “(a) toward objects other than people of the opposite sex, (b) toward sexual acts not usually associated with coitus, or (c) toward coitus performed in bizarre circumstances” (APA, Diagnostic and statistical manual of mental disorders, 1968, p. 44). The DSM-III (APA, 1980) maintained most of DSM-II’s (APA, Diagnostic and statistical manual of mental disorders, 1968) sexual deviations appearing now as paraphilias but also included gender identity disorders as well as psychosexual dysfunctions. Although the DSM-III (APA, Diagnostic and statistical manual of mental disorders, 1980) was developed utilizing extensive field testing, its revision, the DSM-III-R (APA, Diagnostic and statistical manual of mental disorders, 1987), provided much needed alterations that include (1) the removal of exclusivity or repetition of paraphilic behavior in order to diagnose (replaced with severity codes), (2) the inclusion of recurrent intense sexual urges and fantasies for at least six months, and (3) the inclusion of the individual either acting on these urges/fantasies or is markedly distressed by them. In a slight, but significant change, the DSM-IV (APA, Diagnostic and statistical manual of mental disorders, 1994) removed the DSM-III-R’s (APA, Diagnostic and statistical manual of mental disorders, 1987) inclusion of acting on their sexual urges and input that their fantasies, urges, and/or behaviors result in clinically significant distress or impairment in important life areas. However, the DSM-IV-TR (APA, Diagnostic and statistical manual of mental disorders, 2000) focused on the paraphilias with a nonconsenting victim (e.g., pedophilia, frotteurism, etc.) and reverted back to DSM-III-R’s (APA, Diagnostic and statistical manual of mental disorders, 1987) criteria where the individual is required to either act on their sexual urge/fantasy OR experience distress based on their urge/fantasy. Presently, paraphilic disorders included in the DSM-5-TR (APA, Diagnostic and statistical manual of mental disorders, 2022) have a qualitative nature of the paraphilia (Criterion A; e.g., touching/rubbing against a nonconsenting individual in frotteuristic disorder) and a negative consequence due to the paraphilic behavior (Criterion B; e.g., distress or impairment in social, occupational, or other area of functioning due to frotteuristic behavior). Therefore, a situation may occur where an individual meets Criterion A (qualitative experience) of a paraphilic disorder but not for Criterion B (no distress); in this instance, the individual is said to have a paraphilia but not a paraphilic disorder.
Indeed, sexual behavior has undergone numerous conceptualizations and interpretations. Over time, it has been repeatedly shown that professionals continue to struggle distinguishing between what is considered to be a sexually deviant act(s) and what is a mental disorder; this has significant implications on the assessment of abuse-related sexual interests. In this chapter, referral questions for assessing individuals with perceived paraphilic disorders as well as self-report, psychophysiological, and proxy measure approaches to clinical assessment will be reviewed.
