Research indicates that sexual violence affects about 30% of women in the general population and between two to three times as much for autistic women.
We investigated prevalence of sexual abuse, autistic traits and a range of symptoms, using an online survey addressed to the women of the French autistic community (
Both case identification methods yielded high figures: 68.9% victimization (open question) compared to 88.4% (standardized questionnaire). Two thirds of the victims were very young when they were first assaulted: among 199 victims, 135 were aged 18 or below and 112 participants were aged 15 or below. 75% of participants included in our study reported several aggressions. Analyses indicate that primo-victimization was highly correlated to revictimization and that being young increased that risk. Young victims were also at higher risk of developing post-traumatic stress disorder. A third of the victims reported the assault. 25% of those were able to file a complaint (
Those findings indicate a very large proportion of victims of sexual assault among autistic women, consistently with previous research. The World Health Organization states unambiguously that sexual violence is systemic and that vulnerable individuals are preferably targeted by offenders. We therefore postulate that it would be erroneous to consider that victimization of autistic women is mainly due to autism. On the contrary, autism seems to be just a vulnerability factor. Some authors propose that educating potential victims to better protect themselves would help preventing abuse. We reviewed this proposition in the light of our results and found it to be impossible to apply since more than half of the victims were below or at the age of consent. Literature about sexual violence is discussed. Large-scale prevention programs proposed by World Health Organization and the Center for Disease Control aim at cultural changes in order to diminish gender inequality, that they identify as the very root of sexual violence.

Sexual violence is a major societal issue. World Health Organization (WHO) states unambiguously that ‘‘Sexual violence is a serious public health and human rights problem with both short- and long-term consequences on women’s
Sexual victimization is very common in the general population (
The last decade, however, has seen a steady change taking place: there is a growing movement of victims who have found strength in numbers through social media. They have become able to face social stigma in order to report what happened to them (e.g., child abuse in church, abuse on women in the entertainment industry, abuse on teenagers in competitive sports, etc.). Such social movements might be beneficial for victims in that they realize that they are not alone and can find support. They might also be beneficial for society in that they help acknowledging the extent of the problem, since the massive amount of testimonies published everywhere demonstrate that sexual abuse victims are much more numerous than previously believed.
Statistics on prevalence in the general population indicate elevated rates of victimization all over the world. The recent WHO publication might be the most reliable reference on this topic (
Sexual victimization rates represent about one woman out of three and one child out of ten. Readers may not have expected such elevated figures, especially since many previous studies have reported lower rates (although a few studies actually reported higher numbers) (
Despite this geographical and methodological variability, the
Several researchers have investigated whether autistic women would exhibit higher levels of victimization than women in the general population. Given that being on the autism spectrum condition is characterized by experiencing difficulties in social communication, such as decoding hidden intentions and emotions of others, understanding implicit communication and elements of context, it is expected that women on the spectrum may be at considerable risk for sexual victimization, a hypothesis confirmed by all published studies on this topic. To this end, we have attempted here to conduct an exhaustive review of such research.
However, those six studies cited above did not report whether there were differences between male and female participants. Yet, since women are disproportionately more at risk of sexual victimization than men in the general population, it seems very likely that a similar difference would be observed within the autism spectrum. Indeed, in a large scale Swedish longitudinal twins’ study, 18 years old autistic female participants presented an “almost three times increased risk of self-reported coercive sexual victimization.” Female participants with ADHD were also more victimized than controls, with a two times increased risk (
We tentatively conclude from this short review that being autistic means undergoing a 10–16% risk of enduring sexual molestation as a child and a 62–70% risk of being sexually victimized in adulthood. Most victims are girls and women: autistic female risk of being sexually assaulted is between two and three times as much than non-autistic females and about four times as much than autistic males. Those figures are consistent with the general population rates: around 30% of women and 12% of children are sexually victimized in their lifetime.
In the line of this research, we have conducted an internet-based survey in order to measure the prevalence of sexual victimization in women on the autism spectrum (
This internet-based study was conducted in France in April and May 2018. A total of 234 participants completed the questionnaire. Our final sample was

Due to social and communication difficulties, many women on the autism spectrum join online autism communities where they can find help and support from peers and where they may feel more comfortable discussing issues of sexual violence that they have experienced. We have contacted several local organizations dedicated to autism (
After a short description of the study, women were asked to participate in this survey if they were identifying as autistic women. Participants provided consent for their data to be used in the study after completing anonymously the online questionnaire. A trigger warning was included before questions regarding victimization, as well as an invitation for victims to contact a health practitioner. After pre-submission, the president of the ethics committee of Paris V decided that it was not necessary to review the study insofar as the participants were strictly anonymous (no identifying data were collected, nor IP addresses of respondents). As per French laws regarding data privacy, the questionnaire was declared to CNIL authorities (National Commission on Informatics and Liberty) under identifier # 2172655.
All participants answered to three questionnaires, for a total of 38 questions, using an online survey system
Questions #1–6: socio-demographic information.
Questions #7–9: health level and A.S.D diagnosis.
Questions #10–12: sexual activity and sexual orientation.
Question #13: victimization status in an open question form allowing multiple responses. Choices were as follows: (1) I haven’t been sexually assaulted; (2) I have been sexually assaulted; (3) I have been raped; (4) I underwent an attempted rape; (5) I do not know; (6) Other (with open field).
Questions #14–27: autistic traits (RAADS-14 scale) (
Questions #28–31: victimization level (items 1, 2, 3, and 5 of the Sexual Experiences Survey (SES) scale – Short Form Victimization) (
Questions #32–33: age at first assault and revictimization status.
Question #34: for victims, did they report the assault (with no specification to whom)? And what were the consequences of reporting (being believed or not; receiving psychological care or not; filing a complaint or not)?
Question #35: for victims, what could have prevented the assault? (listed options were chosen by the authors based on clinical interviews).
Question #36–37: presence of psychiatric disorders and assessment of consequences following the assault.
Question #38: participants’ consent to have their responses used in this study.
The RAADS scale is considered to be one of the most reliable self-report screening tools for ASD. In the validation study of the RAADS-14 based on the 80 item Ritvo Autism and Asperger Diagnostic Scale-Revised [RAADS-R (
We calculated the mean, median and standard deviation of the RAADS scores across our sample of participants. We also calculated scores for the three sub-components of RAADS: “social communication” (columns 1, 4–6, 8, 9, and 11); “hyper-focalization” (columns 12–14) and “sensory reactivity” (columns 7 and 10).
In order to assess victimization status of participants, we used a French translation of items 1, 2, 3, and 5 of the Sexual Experiences Survey Short Form Victimization questionnaire (SES-SFV). The Sexual Experiences Survey (SES) and its recent 10-items update (SES-SFV) are the most widely used measures of unwanted sexual experience (
Of important note, we did not apply the recommended analysis method for answers to SES-SFV, which distributes them into six situations: non-victim, sexual contact, attempted coercion, coercion, attempted rape and rape. This is due to the fact that the distinction between coercion and assault does not exist in France, where sexual relationships obtained through coercion are legally categorized as rape in France. Therefore, we have used the following categories instead: sexual touching (s1), oral rape (s2), vaginal/anal rape (s3) and attempted rape (s4). In our analyses, (s2) and (s3) were pooled together in a single category titled “rape.”
Statistical analyses were realized with R (R 4.1.1 2021.08.10). We used the following methods

Distribution of RAADS scores of self-diagnosed participants compared to the distribution of all participants.
Hundred and fifty-five (68.9%) participants declared being victim of one or another form of sexual violence. 22 (9.8%) participants declared not having been victimized while 39 (17.3%) declared that they did not know. Declared victims were distributed as follows: assault: 117 (52.0%); rape: 69 (30.7%); attempted rape: 23 (10.2%).
Hundred and ninety-nine (88.4%) participants reported being victim of one or another form of sexual violence. Twenty-six (11.6%) participants declared not having been victimized. Reported victims were distributed as follows: sexual touching and/or rape attempt: 196 (87.1%); rape: 155 (68.9%).
While some participants reported only one type of aggression, others reported being victims of several types of aggressions, as illustrated in

It happened several times with the same offender: 91 (40.4%)
It happened several times with several offenders: 126 (56.0%)
Non-victims: 26 (11.6%)
Participants reported that offenders used different strategies depending on the type of aggression, as illustrated in
Strategies used depending on the type of assault.
Participants reported consequences of the aggression during the 6-month period following the assault. As illustrated in
Consequences of assault within 6 months of happening.

Among the 199 victims, 111 (55.8%) did not report the assault. Among the 69 who told others about the assault, 18 (26.1%) were not believed. Among the 51 who reported the assault and who were believed (25.6% of the victim total), 34 (66.7%) received no care and no complaint was filed, 8 (15.7%) received care and a complaint was filed, 4 (7.8%) did not receive care but a complaint was filed, 5 (9.8%) received care but no complaint was filed. The remainder of victims either answered “other” (16, 8%) or were among the 29 participants (12.9% of the full sample) who answered “not applicable” alongside the non-victims.
Participants also chose which of the following sentences best reflected their own opinions regarding prevention methods:
Sexual manipulators or predators seem to spot you more easily because of your difficulties in sexual interactions:
Knowledge of self-affirmation strategies learned in therapy (or social skills groups) could have helped you stay safe better:
Your family members should have been more attentive:
Female teenagers with Asperger syndrome and their parents should be better informed about the risk of sexual abuse:
Nothing could have protected you from this or these assault(s):
Health professionals should have given you adapted prevention advice such as better identifying sexually ambiguous situations with men:
The officials of the institution (high school, university, company) in which you were should have been more watchful:
Not applicable (this is not relevant to me):
In order to compare answers from the two sexual assault questionnaires, we checked overlaps and incongruencies between Question#13 and SES questionnaire. We looked at how many participants who had chosen at least one of the positive answer columns (the assault, rape and attempted rape options) in the open question were also victims according to SES, checking the same for participants who hadn’t. We also looked at how many participants who didn’t know or declared being non-victims in the open question were nevertheless victims according to SES, and how many weren’t.
While 153 (68%) participants reported victimization in both SES and question#13, there were 46 (20.4%) participants who did not identify as victims in question#13 but nevertheless were classified as victims according to the SES questionnaire. On the other hand, only 2 (<1%) participants reported being victims when answering to question#13 but were not categorized as victims according to SES questionnaire.
Also, among the 39 participants who answered “I don’t know” to question#13, 34 of them were actually categorized as victims according to SES questionnaire. More precisely, those 34 victims reported one or more of the following assaults: Sexual touching: 31 (91.2%); rape: 22 (64.7%); rape attempt: 16 (47.1%).
Moreover, among the 22 participants who answered being non-victims to question#13, 5 were recategorized as victims according to SES questionnaire, distributed as follows: Sexual touching: 3 (60%); rape 1 (10%); rape attempt: 4 (80%). Those results are illustrated in
Comparison of assaults reported by participants through the two questionnaires.
In order to check consistencies between the two modes of investigation (question#13 and SES), we used two methods: Chi-square tests and Mc Nemar tests were run on the contingency tables.
Chi squared tests results were as follows and remain significant after a Bonferroni correction:
Sexual touching (SES) or assault (open question):
Rape:

In order to investigate whether being victim of one assault increases the risk of revictimization, we used conditional probabilities within SES questionnaire, with the following results:
We ran Chi-square tests on the contingency tables within SES questionnaire (see

In order to test if victimization increased the risk of a specific type of comorbidity, we ran two-sample tests of equal proportions within SES, leading to the following p-values:
Post-traumatic stress disorder rates depending on age at first assault.
In order to test whether SES victimization increased the risk of PTSD, we ran logistic regressions with the following results:
In order to investigate whether multiple assaults perpetrated by one or several offenders made a difference regarding the risk of developing a PTSD, we ran two-sample tests of equal proportions within SES, with the following results:
Victims of several assaults from several offenders and victims of only one offender (be it one or several assaults):
Victims of several assaults from same offender and other victims (several offenders + only one assault):
We also ran logistic regressions among victims in order to test if the risk of developing PTSD was increased by multiple victimization by

We investigated whether presentation of autistic traits constituted a risk factor for sexual victimization. In order to compare RAADS scores of victims and non-victims according to SES, we used Wilcoxon tests and logistic regressions. Adding current age and education level as independent variables to the logistic regressions did not significantly change the results. Results are illustrated in

The description of our population sample is revealing of what autism in women looks like and is in line with previous studies (
We asked participants if they had received IQ testing. Among the 66.2% who answered yes, 82.5%, (
More than half of the participants (57.8%) were involved in a relationship and more than half (55.6%) had been sexually active over the last six months (mostly the same individuals, 77% of them being in a relationship while the remainder was not). Of important note, more than half of our sample had only experienced heterosexual sex over their lifetime, despite the extremely high percentage of declared queer orientations (71.6%). This gap between aspiration and experience might be partly explained by social factors that are non-specific to autistic women (i.e., cultural stereotypes, lower proportion of potential partners…), but could also be linked to autistic characteristics, such as camouflaging and social imitation strategies that have been previously described in autistic women (
Interrogated about their health, while only 17% of participants reported poor health status, more than 75% reported at least one psychiatric comorbidity, as if mental health disorders comorbidities were not health issues. Depression and anxiety were by far the most prevalent comorbidities (62.2 and 56.4% respectively). PTSD came in third place (26.7%). These results should however be interpreted cautiously because of the absence of structured clinical interviews for psychiatric diagnosis in this study. Considering that all these findings are in agreement with reports and studies on the topic of autism in adult women, it is reasonable to see our sample as reliably representative (
In order to confirm autism diagnosis reported by participants, we collected their RAADS scores. We only included in the analyses participants who obtained RAADS score > 14 (merely two participants were excluded solely on that criterion). Mean RAADS in our sample was equal to 34.9 ± 5.2 and median was equal to 36, well above the median = 32 reported in the validation study of that scale (
We assessed victimization status twice: through an open question (Question#13) and through a specific questionnaire (SES-SVF). Both methods yielded extremely high figures: open question resulted in 68.9% victimization, compared to 88.4% with SES-SFV questions. Those results are very high but nonetheless extremely consistent with the findings that we have reviewed earlier: a rate of almost 30% victimization in non-autistic women and a 2 to 3-fold increased victimization of autistic women (
Regarding ascertainment procedure, we used two methods of case identification. As expected, the SES-SVF questions revealed a significantly higher level of victimization than the open question. This confirms that it is necessary to ask questions about specific situations, rather than using open questions, in order to identify all victims, since some victims may need many years of processing memories about the assault before realizing that the non-consensual sex that happened to them qualifies as a legal offense/crime. One participant wrote this “It happened many times over my lifetime (as child, as a teen, as an adult). It is only 5 years ago, at the age of 50, that I understood that I had been victim of sexual violence.” Another participant wrote “This event remained out of my consciousness’ access for many years.” We indeed found several instances of such confusion in our sample: 34 out of 39 participants who answered “I don’t know” to the open question were nevertheless identified as victims through SES. Furthermore, 5 out 22 participants who responded “non-victim” to the open question were actually victims according to SES. Last, Chi-squared test results indicated that participants were consistent: all but two of those who declared being victim in the open question declared the same thing in SES-SFV questions.
Sexual revictimization among our participants was very important: 84.9% of victims were revictimized (
We used four different statistical methods to assess whether being victim of one assault increased the risk of being victim of another one, and all yielded significant results, reaching a clear-cut conclusion that, yes, primo-victimization is a major gateway to further victimization. This is actually also the case for non-autistic women: half of those who were molested as children will suffer from new occurrences of sexual violence later in life (
Being young made things worse in our sample: young age was a significant factor of revictimization later in life. One possible contributor to this mechanism is that children who are molested often exhibit disturbed behaviors. As
As mentioned in the introduction to this text, sexual violence has a very negative impact on health. In our sample, participants who had endured sexual violence exhibited significantly more comorbidities than participants who hadn’t. Further testing suggested that, among all comorbidities, it is specifically PTSD that is increased after the aggression, in accordance with a recent meta-analysis (
Besides PTSD, victims also reported consequences that occurred within the 6 months following the assault. Half of them suffered from sleep disorder (48.2%) and disgust for sex (46.7%) and third of them attempted self-harm (31.7%). It is specifically rape that induces such deleterious effects, as opposed to victims of attempted rape only or unwanted sexual touching only. Of course, this is to be interpreted with caution because there is a discrepancy in sample sizes: 44 victims did not endure rape while 155 did.
Other major vulnerability factors associated with autism and with mental health issues such as social isolation, social stigma and social rejection should be further studied in order to better describe the mechanisms of abuse (
In our study, only a third of the victims reported the assault (34.6%,
We have explored whether autistics traits, translated into metrics thanks to the RAADS scale, could be related to victimization. Results do not indicate clearly that autism is in itself a factor. Indeed, we found only one significant result: logistic regression indicated that the higher someone scores on the “sensory reactivity” sub-scores of the RAADS scale, the more elevated the risk of sexual victimization is. It is impossible to infer the direction of a putative causal effect, or even if it is just a correlation due to a confound yet to be determined. Very reactive individuals are indeed easily identified (they may wear sunglasses or noise canceling headphones) and that may help sexual predators to spot them. However, it could be the opposite: victims could display heightened reactivity due to trauma (a PTSD symptom). And last, it could be two effects of a common cause: for example, the trauma of being severely bullied at school could increase such sensitivity while at the same time making the victims more vulnerable to sexual violence.
However, a true effect of autism cannot be excluded of course. We did find a significant correlation between PTSD and total RAADS score after all, and PTSD was significantly correlated with victimization. But that could be interpreted both ways: (i) high autism traits lead to more victimization, leading to more PTSD, or (ii) PTSD might be the confound mentioned above, with PTSD being at the same time a consequence of sexual violence and the cause of heightened sensitivity in adulthood. In any case, it must be reminded here that the very small number of non-victims, the statistical negative results of our between group comparison are not very reliable. The absence of proof is not proof of absence and further research is needed here.
At that point, it seems important to ponder about the fact that several of the publications that we have cited above mention sexual education as the primary prevention method against sexual violence.
This is not to say that there is no need to be informed. Quite the opposite, sex education is very important for everyone in order to foster safe relationships. But, according to
It seems intuitively right that, since autistic girls may misunderstand the complex games of flirting and dating, teaching them on how to behave in romantic relationships would help them achieve a satisfying love life (
Beside those considerations, another major criticism against the “preventing through sex educating” method is that victims are very often in a state of stupor and dissociation during the assault. They are therefore unable to react, sometimes even unable to comprehend, and no education can prevent that. Let’s remember here that the overwhelming majority of sex crimes are committed by persons who are closely related to the victims, a parent, a teacher, a boyfriend (
The SES-SFV responses provided yet another counterargument to the model of sex education as a prevention tool in that it collects information about the strategies used by offenders. Perpetrators primarily used two strategies to violate and abuse: manipulation/mental ascendency/harassment (“a”) and using surprise to take advantage (“c”). Strategy “c” was the first choice for imposing unwanted sexual contact, while strategy “a” was preferably used for rape attempt and rape. This might prove crucial for understanding why and how sexual violence happens so often in this population. As we have seen, one out of three non-autistic women is a victim of sexual violence. How could autistic women who, by very definition, are ingenuous and cannot guess hidden motives, defend themselves better than non-autistic persons against deviousness, treachery and deception? As
Interrogated about prevention methods, one victim out of ten answered that nothing could have protected them. One out of four considered that their autistic traits made them easy to spot by sexual predators. Four out of ten thought that knowledge about risk and self-affirmation strategies could have prevented the assault. However, as we asserted, the high proportion of underage victims renders such a method irrelevant since it would mean putting the responsibility of avoiding victimization on the shoulders of the minor victims.
In addition, it is very important to remember that, contrary to widespread myths regarding rape, offense is almost always perpetrated by a close person, exploiting ascendancy or hierarchical power over the victim. What could education do against situations such as the ones reported by our participants: “I was repeatedly raped by a relative during infancy and childhood”; “the first time, I was 6 years old”; “someone who had authority over me (father)”? On the contrary, as mentioned by one out of five participants, the most efficient protection, especially in the case of vulnerable individuals, is the presence of a vigilant caregiver. Educating families and professional about the risk of sexual victimization of girls on the autism spectrum should therefore be a priority.
Our research indicates that almost 9 autistic women out of 10 are sexually victimized, at huge costs for their mental and physical health. Of course, one major limitation of our study is that it is based on voluntary participation and that represents a bias since concerned individuals, i.e., victims, may be more willing to contribute to such research than non-victims. However, this bias might not impact results a lot, since our findings are very consistent with literature about sexual violence against autistic women and against women in general. So, what could be done to prevent such generalized issue? The WHO study (
Prevention is absolutely necessary, certainly not in the sole form of sex education but rather by promoting profound cultural changes such as recommended by the Center for Disease Control (CDC) and World Health Organization (WHO): both organizations indeed strongly affirm that the very root of sexual violence is gender inequality. As Jessica Leight formulates it (

Quality research on autism cannot be conducted without the input of concerned individuals. We are deeply grateful to Marie Rabatel who drew our attention to the importance of Post-Traumatic Stress Disorder consecutive to sexual violence in autistic women. She was also of invaluable help for broadcasting this study toward potential participants. We extend our thanks to French non-profit organizations such as

“High functioning” here means that our participants had to be able to fill a questionnaire in order to be included.
We are doubtful of Brown-Lavoie conclusion because the sex education they assessed was about STD and birth control, not about being safe from abuse. It is very possible, however, that sex education as they defined it was a confound.
