Lock and Protect: Reducing Adolescent Access to Lethal Means of Suicide

The primary goal is to determine the acceptability and feasibility of implementing the Lock and Protect decision aid. The secondary goals are to identify the potential short-term impact of Lock and Protect on home firearm and medication storage, parental self-efficacy. Using interviews with caregivers, the study will clarify the acceptability, feasibility, and barriers to implementing the Lock and Protect hone safety plan. This will allow further development of effective strategies to subsequently further test and use Lock and Protect in the ED. NOTE: The study will only recruit guardians and their adolescents from the pediatric ED at Morgan Stanley Children's Hospital NY-Presbyterian.
