Some Triads establish programs to prevent eider abuse through education and to address the plight of seniors in personal care homes.
It is this type of cooperative networking that makes Triads not only successful but satisfying as well.
Some Triads design programs that offer reassurance to seniors and protect their welfare.
In order to increase the seniors' sense of security, a number of Triads have begun or expanded telephone reassurance programs that already exist in some law enforcement agencies.
The Triad concept emerged in 1987, when several members of the International Association of Chiefs of Police (IACP), National Sheriffs' Association (NSA), and members of the American Association of Retired Persons (AARP) met to consider mutual crime prevention concerns and to plan for the future.
This effort was quickly dubbed Triad, representing the three-way cooperative effort between sheriffs, police chiefs, and the AARP, which represents the senior citizen population.
In some areas, the formation of a Triad has made the resources and program elements that were previously available to only town or county residents available to residents of both incorporated and unincorporated areas.
