People with Disabilities Rights Protection Act announced in 2007 stipulates a brand new regulation that individuals with disabilities be provided marriage and fertility counseling and support services based on the assessment of their needs. According to the ”Five-year Sunrise Clause”, the new provisions will be in carried out in 2012, with a need to refer to other countries' practical experiences or approaches, such as the PLISSIT model.The PLISSIT model, developed by Annon (1976), includes four aspects of sexual treatment: Permission (P), Limited Information (LI), Specific Suggestions (SS), and Intensive Therapy (IT). The model using educational, counseling, and therapy approaches deals with individuals with intellectual disabilities on a variety of sexual issues.This model, developed for many years, is applicable to different people, facilities, and time, and can help the helping staff to clarify the degree of their comfort with and mastery on sexuality. If their professional preparation is insufficient, the staff may refer the individuals to other experts.The application of the PLISSIT model may foster all the people in helping professions to think, in both micro and macro ways, about the following important issues, including: to propose the professional knowledge of sexuality education that staff should possess, to cooperate with multi-discipline professionals to treat the sexual issues of individuals with intellectual disabilities, and to develop sexuality policies and guidelines for individuals with intellectual disabilities.
