CDC: Youth Risk Behavior Surveillance

Apart from the National Intimate Partner and Sexual Violence Surveys (NISVS) CDC also performs at regular intervals a survey among high school students called “Youth Risk Behaviour Surveillance” and has done so since the 1990s.

 

In 2001 they added the question

Have you ever been physically forced to have sexual intercourse when you did not want to?

to the survey.

 

Below is a chart showing the results of that questions since 2001 and up to the latest available data which is from 2015:

Sex Exchange More Common Among Boys

An earlier post of mine titled “And Boys Too…” looked at the prevalence of teen prostitution among boys in different countries. I noted that to some extent there are more teen aged male prostitutes than teen aged female prostitutes based on a handful of studies.

Here is another US study using a nationally representative sample of adolescents and young adults which found that more males reported exchanging sex than females.

Ulloa, E.; Salazar, M.; & Monjaras, L. (2016). Prevalence and Correlates of Sex Exchange Among a Nationally Representative Sample of Adolescents and Young Adults. Journal of Child Sexual Abuse, 25(5), 524-537.

It used data from The National Longitudinal Study of Adolescent to Adult Health.

 

 

Bias And Unasked Questions

STIRitUP is a 24 month collaborative research project looking at interpersonal violence and abuse in young people’s relationships. The project is based in five European countries: England, Bulgaria, Cyprus, Italy and Norway. STIR is short for Safeguarding Teenage Intimate Relationships.

The project has conducted a survey among 4,500 pupils in these five countries. STIRitUp has published the results of that survey in the Briefing paper 2. This paper presents the survey’s main findings in table 2 — here is an excerpt of that table (only looking at physical and sexual violence):

Gender and incidence rates for experiencing IPVA

Country Gender Physical % Sexual %
Bulgaria Female 11 21
Male 15 25
Cyprus Female 10 17
Male 9 19
England Female 22 41
Male 12 14
Italy Female 9 35
Male 13 39
Norway Female 18 28
Male 8 9

Discrepancies

First I’ll just point out the discrepancies between the findings presented in the table and how they’re presented in the text.

UK: CSEW doesn’t count all sexual offences

The Crime Survey for England and Wales (CSEW), formerly known as the British Crime Survey (BCS), is a face-to-face victimization survey first conducted in 1982. Here is a bulletin describing what the Ministry of Justice, Home Office and the Office for National Statistics says about what sexual offences the CSEW captures:

These experiences span the full spectrum of sexual offences, ranging from the most serious offences of rape and sexual assault, to other sexual offences like indecent exposure and unwanted touching.

Unfortunately that is a lie and this blog post will explain in some detail why this is a lie and what sexual offence is left out.

Koss again

I’ve previously written about Mary P. Koss’ 1993 paper Detecting the Scope of Rape : A Review of Prevalence Research Methods in a post titled Exactly what is inappropriate? and how she recommends one defines rape.

Some may argue that 1993 is 20 years ago and that she might have changed her opinion since then.

So let’s take a look.

UK: NATSAL-3 and a bit of NISVS 2010

NATSAL-3 is short for National Survey of Sexual Attitudes and Lifestyles 2010-2012. Currently six papers on this survey is published in The Lancet.

Among the things measured by this survey was non-volitional sex and one of the Lancet papers is on this subject:

Lifetime prevalence, associated factors, and circumstances of non-volitional sex in women and men in Britain: findings from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3)

America (and Salon) still doesn’t know how to talk about rape

The title isn’t mine, I’ve shamelessly stolen it from this article on Salon written by Mary Elizabeth Williams.

It’s quite astounding that an article titled in such a way by Williams is so full of fail.
