Your assignment is to prepare and submit a paper on sexual crime assessment and treatment. Assessment of a passive clinical or psychological problem is important to inform and identify the method of treatment and also determine indicators of risk involved. To make a successful mental health assessment of Joe’s case and determine the presence or absence of mental illness, a complete history of the behavior of the victim is necessary, beginning taking static data such as age and gender. Any relationship between potential mental illness and sexual behavior by the victim would be studied. Here, we undertake a psychosexual history analysis of the offender to establish association or non-association of habits such as sexual preoccupation that include repeated sexual fantasies or not easy to control sexual urges, and hyper-sexuality activities involving but not limited to things like masturbation or many sexual partners. Depending on the assessment, if the presence of any form of sexual fantasies is diagnosed, this might mean the existence of paraphilia, in which case the depth of the problem in terms of the number of times the habit is repeated and at what strength must further be examined. Where mental illness exists with a paraphilia, it is important to assess the timing of the occurrence of the latter given the presence of the former. We should also not forget to incorporate the possibility of substance abuse as a cause or related to sexual habits by the offender (Rosler & Witztum, 2000). Usually, the use of a self questionnaire is encouraged because the offender would be willing to provide more information unlike the face to face interview. The input of friends and family is also vital.&nbsp.An investigative assessment of a sex offender case may involve looking at mainly historical data and information about the individual. These may be previous criminal records available, number of sex offenses committed, evidence of response to sexual and no-sexual violence, present and past behavioral experience with small children, and evidence of social isolation.
