Clinical Descriptions and Diagnostic Requirements for ICD-11 Mental, Behavioural or Neurodevelopmental Disorders
Paraphilic disorder involving solitary behaviour or consenting 
individuals
Essential (required) features
• A sustained, focused and intense pattern of atypical sexual arousal – as manifested in 
sexual thoughts, fantasies, urges or behaviours – that involves consenting adults or solitary 
behaviour is required for diagnosis.
• One of the following two elements must be present.
• The individual is markedly distressed by the nature of the arousal pattern and the distress 
is not simply a consequence of rejection or feared rejection of the arousal pattern by 
others.
• The nature of the paraphilic behaviour involves significant risk of injury or death either to 
the individual (e.g. asphyxophilia or achieving sexual arousal by restriction of breathing) 
or to the individual’s partner (e.g. consensual sadism that results in injuries requiring 
medical attention).
• If the diagnosis is assigned based on significant risk of injury or death, this risk should be 
directly and immediately connected to the paraphilic behaviour. For example, a presumed 
risk of increased exposure to sexually transmitted infections is not a sufficient basis for 
assigning this diagnosis.
Additional clinical features
• Paraphilic disorder involving solitary behaviour or consenting individuals should not be 
diagnosed among children, and should be diagnosed only with the utmost caution among 
adolescents. Sexual experimentation is typical during adolescence, and sexual acts may 
occur impulsively or opportunistically rather than representing a recurrent pattern of 
sexual arousal.
• Diagnosis of paraphilic disorder involving solitary behaviour or consenting individuals 
generally requires a report of sexual thoughts, fantasies, urges and behaviours directly from 
the individual in order to document a sustained, focused and intense pattern of atypical 
sexual arousal, and the degree and sources of related distress.
Boundary with normality (threshold)
• The fact that an individual’s pattern of sexual arousal deviates from social or cultural norms 
is not a basis for assigning a diagnosis of paraphilic disorder involving solitary behaviour 
or consenting individuals. An arousal pattern that involves consenting adults or solitary 
behaviour, and that is not associated with marked distress that is not simply a consequence

of rejection or feared rejection of the arousal pattern by others or with a significant risk of 
injury or death, is not considered a disorder.
• The occurrence or a history of atypical sexual behaviours is not sufficient to establish a 
diagnosis of paraphilic disorder involving solitary behaviour or consenting individuals. 
Some atypical sexual behaviours may occur impulsively or opportunistically, or as a means 
of personal and sexual exploration, and are not associated with a sustained underlying 
arousal pattern. The diagnosis of paraphilic disorder involving solitary behaviour or 
consenting individuals requires these behaviours to be a manifestation of a sustained, 
focused and intense pattern of paraphilic sexual arousal, in addition to distress or 
significant risk of injury or death.
• When distress related to an arousal pattern involving consenting adults or solitary 
behaviour is entirely attributable to rejection or feared rejection of the arousal pattern by 
others (e.g. a partner, family, society), a diagnosis of paraphilic disorder involving solitary 
behaviour or consenting individuals should not be assigned. Instead, categories from the 
grouping QA15 Counselling related to sexuality in Chapter 24 on factors influencing 
health status or contact with health services may be considered.
• This diagnosis should not be applied to individuals who are distressed about homosexual 
or bisexual sexual orientation. If an individual is presenting for treatment based on such 
distress, categories from the grouping QA15 Counselling related to sexuality in Chapter 24 
on factors influencing health status or contact with health services may be considered. If 
the pattern of distress-related symptoms meets the diagnostic requirements for another 
mental disorder (e.g. adjustment disorder, a depressive disorder, an anxiety or fear-related 
disorder), that diagnosis should be assigned.
Course features
• Individuals with paraphilic arousal patterns involving solitary behaviour or consenting 
individuals often report the onset of paraphilic sexual interest during adolescence.
• Paraphilic arousal patterns are relatively stable after young adulthood, but sexual thoughts, 
fantasies, urges and behaviours, as well as any associated distress, may change over time, 
such that an individual who was assigned a diagnosis of a paraphilic disorder involving 
solitary behaviour or consenting individuals no longer meets the diagnostic requirements.
Developmental presentations
• Advancing age may be associated with decreasing paraphilic sexual arousal and decreasing 
related behavioural manifestations due to increased impulse control and decreased sexual 
drive.

Sex- and/or gender-related features
• Paraphilic arousal patterns involving solitary behaviour or consenting individuals are 
much more prevalent among men.
• Paraphilic arousal patterns involving masochism are more prevalent among women than 
other paraphilic arousal patterns. If other diagnostic requirements are met (e.g. marked 
distress or significant risk of injury or death), a masochistic paraphilic arousal pattern may 
be a part of the basis for diagnosis of paraphilic disorder involving solitary behaviour or 
consenting individuals.
Boundaries with other disorders and conditions (differential diagnosis)
Boundary with compulsive sexual behaviour disorder
Both paraphilic disorder involving solitary behaviour or consenting individuals and compulsive 
sexual behaviour disorder may involve repetitive sexual impulses, urges or behaviours that result 
in marked distress or impairment. Paraphilic disorder involving solitary behaviour or consenting 
individuals is characterized by sexual impulses, urges or behaviours that are manifestations of 
a sustained, focused and intense pattern of atypical sexual arousal that is associated with either 
marked distress or significant risk of injury or death. In contrast, compulsive sexual behaviour 
disorder is characterized by a persistent pattern of failure to control sexual impulses, urges or 
behaviours, regardless of the focus of sexual arousal. If an individual with paraphilic disorder 
involving solitary behaviour or consenting individuals is able to exercise some degree of control 
over the behavioural expressions of the arousal pattern, an additional diagnosis of compulsive 
sexual behavioural disorder is generally not warranted.
Boundary with disorders due to substance use
Episodes of sexual behaviour that are atypical for the individual may occur during substance 
intoxication. Such episodes may not be a manifestation of a sustained, focused and intense sexual 
arousal pattern. At the same time, some individuals with paraphilic disorders may use substances 
with the intention of engaging atypical sexual behaviour that does reflect an underlying paraphilic 
arousal pattern. A diagnosis of paraphilic disorder involving solitary behaviour or consenting 
individuals may be assigned together with a disorder due to substance use if the diagnostic 
requirements for both are met.
Boundary with other mental disorders in the context of rejection or feared rejection
If distress related to rejection or feared rejection of the arousal pattern by others has reached a 
point that presenting symptoms meet the diagnostic requirements for another mental disorder 
(e.g. adjustment disorder, a depressive disorder, an anxiety or fear-related disorder), that diagnosis 
should be assigned rather than paraphilic disorder involving solitary behaviour or consenting 
individuals.
