There is not a great deal of empirical research on adolescent sex offenders and even less on mentally retarded adolescent sex offenders. This study provides some preliminary data in this area. Results of a survey of the extent and types of sexual problems evident amongst groups of mentally retarded and intellectually normal adolescents (N = 196), seen at an assessment and treatment centre in southwestern Ontario during a 14 month period is presented. In addition three groups of ten adolescents each (mentally retarded and intellectually normal sex offenders and one group of mentally retarded non-offenders with behavioural problems) were investigated to gain a more indepth perspective of characteristics of these adolescents and their backgrounds. Considering the high recidivism rate for these groups, indications for treatment are discussed with special consideration for the mentally retarded offenders.
