SAN FRANCISCO (AP) _ Novelist Danielle Steel and a foundation named for her late son have been honored for efforts to make positive changes in the lives of young people.

St. Mary's Medical Center, the University of San Francisco and the Catholic Youth Organization of San Francisco presented the 1999 Service to Youth Award to the writer on Thursday.

Steel established the Nick Traina Foundation in 1998 as a legacy to her son, who suffered from manic depression and died of a heroin overdose two years ago at 19. She recounted his story in her book ``His Bright Light.''

The foundation supports organizations involved in the diagnosis, research, education and family support for those with mental illness, as well as suicide prevention.

Past recipients of the award include Mother Teresa, Bob Hope and Joe and Jennifer Montana.
