Prevalence and Treatment of Frotteurism in the Community: A Systematic Review

This article describes a systematic review of prevalence studies on frotteurism. We searched the following databases for previously published, peer-reviewed studies that used suitable diagnostic methods in adult nonclinical samples: Ovid MEDLINE, PsycINFO, Pubmed, AccessMedicine, Cochrane Library, Books@Ovid, DynaMed, Micromedex, Science Direct, and SciVerse Scopus. We conducted multiple searches using the following terms: frotteu*, frottage, frotteurism, paraphilia, paraphilic, courtship disorder, prevalence, treatment, diagnosis, and chikan , and we evaluated the articles by using a six-point epidemiologic quality tool. We identified four prevalence studies, all of which were of limited methodological quality. Limitations included small sample sizes, the use of local rather than national samples, the failure to apply DSM or ICD-9 diagnostic criteria, and the lack of assessment regarding the reliability of diagnostic tools. One small study, a statistical outlier, reported a prevalence of 35 percent. In the three other studies, the prevalence of frotteurism was 7.9 percent, 9.1 percent, and 9.7 percent. We found no studies addressing treatment that met our inclusion criteria. Our findings reveal a need to develop more rigorous research on this topic.
