The disturbed and disturbing college student causes the most vexing concerns for student affairs administrators. The Assessment-Intervention of Student Problems (AISP) model offers a useful and easily understood framework for dealing with the various challenges of this high-risk student population. This chapter focuses on changes that have occurred in the past 20 years that are particularly challenging to student affairs professionals and their constituents who feel inundated by a myriad of concerns in dealing with disturbed/disturbing students. A brief review of the contemporary student climate is presented, including trends in college student development issues, mental health issues, and illegal or dangerous behaviors. It demonstrates contemporary applications of the AISP model in dealing with contemporary disturbed and disturbing student behaviors. It includes a discussion of intervention strategies currently being used on campuses and the complex legal issues they pose. Finally, it suggests new skill sets that student affairs professionals should develop to address the needs of the disturbed/disturbing students. (Contains 3 notes.)
