From court to the community: Improving access to evidence-based treatment for underserved youth involved in the juvenile legal system at-risk for suicide

Background Juvenile legal involved youth (JLIY) experience disproportionately high rates of suicidal and self-injurious thoughts and behaviors (SSITB). Many JLIY lack access to evidence-based treatment specifically designed to treat SSITB, thereby increasing the overall risk of suicide. The overwhelming majority of JLIY are not placed in secure facilities and almost all incarcerated youth are eventually […]

Social comparison of mental health, deliberate self-injury and help-negation

Those engaging in deliberate self-injury (DSI) demonstrate low professional help-seeking rates. Help-negation in the context of deliberate self-injury refers to a relationship where higher levels of self-injury are associated with lower help-seeking intentions. This study aims to investigate whether social comparison processes and other variables contribute to help-negation. One hundred and eighty-three university students completed […]

The relationship between emptiness and suicide and self-injury urges in borderline personality disorder

Introduction Suicide and self-injury (SSI) are pervasive among individuals with borderline personality disorder (BPD), yet little research has examined factors that increase SSI urges among those with BPD.
