for pedophilia specifies it as a disorder of sexual interest in prepubescent children generally age 13 years or younger. A 2009 research paper by Ray Blanchard and colleagues indicated that, based on penile plethysmographs, sex offenders could be grouped according to the sexual maturity of individuals they found most attractive (because ages are not a specific indication of adolescent sexual development, Blanchard used stimuli with a Tanner scale rating of 1 on essentially all measures to evaluate hebephilic offenders while adult control stimuli all had a Tanner rating of 5). Blanchard noted that the most common age of victims for sexual offenders was 14 years, and suggested there were qualitative differences between offenders who preferred pubertal sex-objects and those with a prepubertal preference. The paper concluded that the DSM-5 could better account for those data if it split the DSM-IV-TR's existing criteria for pedophilia, which focuses on sexual attraction to prepubescent children, but sets the age range at generally 13 or younger. Blanchard suggested the criteria be split into pedophilia as sexual attraction to prepubescent children who are generally younger than 11, and hebephilia as sexual attraction to pubescent children, generally 11–14 years old. What the DSM-IV calls pedophilia would instead be termed pedohebephilia, with pedophilic and hebephilic sub-types. The proposed criteria for the DSM-5 involved an adult who, for six or more months, experienced sexual attraction to prepubescent or pubescent children that was equal to or greater than their attraction to adults, and who also either found the attraction distressing, used child pornography or had sought sexual stimulation from a child, on at least three occasions in the case of the hebephilic type. The proposed criteria would have been applied to subjects aged 18 or older and who are at least five years older than children to whom they are typically attracted. The sexual and gender identity working group justified inclusion of the use of child pornography due to the expectation that pedohebephilic individuals would deny their sexual preferences, leaving it up to the diagnosing clinician to make inferences whether their patients are more interested in children than adults. The altered wording (from "prepubescent" to "prepubescent and pubescent") and reference age (from a maximum age of 13 to 14) would change how pedophilia was diagnosed to include victims with Tanner scale ratings of 2 or 3 who had partially developed some secondary sexual characteristics.
