Illinois has one of the highest teenage and college student suicide rates in the United States. This pilot study assessed suicide ideation and self-harm behaviors at a public Illinois university. This is the first study to use 5 standardized psychological instruments to investigate these 2 crises in freshmen college students who are all required to reside in dormitories. The main hypothesis was to determine if the independent effects of freshmen students' depression, Five-Factor Model, and Reasons for Living affected the dependent variables, self-harm behaviors and suicide ideation. <b>Methods:</b> Forty first-year college dormitory students completed the Beck Depression Inventory-II, Scale of Suicidal Ideation, Five-Factor Model, Inventory of Statements About Self-Injury, and Reasons for Living Scale in person. <b>Results:</b> Participants were 18 to 19 years old, predominantly female (65%), and non-White (62%). Forty percent reported self-harm behaviors and 19% reported suicidal ideation. The top reasons for contemplated suicide attempts included the inability to solve problems (33%) and attention/revenge (28%). Students experienced high levels of anxiety (55%), self-consciousness (43%), and depression (18%). Depression was associated with suicide ideation (β<i> </i>= 0.05, <i>P </i>= .006), while neuroticism and openness were associated with self-harm behaviors (<i>aOR </i>= 3.36, <i>P </i>= .02, <i>aOR </i>= 0.48, <i>P </i>= .047, respectively).
