Bio-Behavioral Markers of Affect Regulation in Teen Suicide Attempters versus Non-Suicidal Self-Injurers

Abstract: This study will identify how adolescents who have attempted suicide differ emotionally from those who engage in non-suicidal self-injury. Three groups of teens will be studied ages 13-17 years: teens who have attempted two or more suicides, who do not engage in non-suicidal self-injury (cutting); teens who cut/self-injure, but who have not attempted suicide; and typically-developing teens without psychiatric illness. The following measures will be made to differentiate bio-behavioral markers between these groups: psychological factors and performance on computerized performance measures of functional and social cognition. This study will be the first to objectively test these theories of affect regulation by using psychological assessments and computerized behavioral tasks to identify bio-behavioral markers of teen suicide and cutting.
