Investigators will present parents with suggested alternatives for restricting lethal means, particularly firearms and medications with high toxicity in overdose. Investigators will present multiple options for restricting access as opposed to just one alternative that may be deemed unreasonable by a family. Investigators will generate these options based upon the expertise of the study's lethal means consultant. Second, the mobile technology platform will provide weekly prompts about means restriction. Parents who have not restricted access to lethal means will be asked to document their reasons for inaction-a justification for not following safe storage practices. Third, the mobile technology platform will provide descriptive normative data regarding means restriction to those who have not secured these items

Families randomly assigned to the control condition will receive a psychological placebo that will feature an education only website developed by NCH's web design team. This website will cover warning signs for suicide, the leading methods of suicide - so that both conditions have content that features information about firearms - and locating professional help. Like the intervention Safer Still web-based program, the control website will be branded with a Nationwide Children's Hospital affiliation, as opposed to an outside organization that will be less familiar to the central Ohio sample. The control website will NOT feature these three behavioral economic strategies--namely (a) multiple suggested alternatives for means restriction, (b) requests to justify inaction regarding means restriction, and (c) normative feedback about means restriction.

An interactive intervention will be developed to help promote safe storage of firearms during the critical period immediately following high-risk care transitions.

The Household Lethal Means Survey (HLMS) asks the parent to indicate whether there are any guns kept in or around the home, and if so to describe how the gun(s) and ammunition are stored. The HLMS will be supplemented with three questions from the 2018 California Safety and Well-Being Survey. These three questions address reasons for firearm ownership, loaded handgun carrying in the past 30 days, and high-capacity magazine ownership. At follow-up, the study survey assesses whether and how firearm ownership and storage practices changed since baseline. Similar questions at baseline and follow-up are asked about lethal medications.

Readiness to change firearm and medication storage practices will be assessed using the Stages of Change Questionnaire (SOCQ), a psychometrically sound 12-item self-report measure ( 5-point Likert scale; -2 = "Strongly Disagree"; +2 = " Strongly Agree"). The scale will be used to measure the four stages of change (Pre-contemplation, Contemplation, Action, and Maintenance). Items numbered 1,3,6,10 Precontemplation, items numbered 2,4,7,11 = Contemplation and items numbered 5,8,9,12 = Action.

A negative scale score reflects an overall disagreement with items measuring the stage of change, whereas a positive score represents overall agreement. The highest scale score represents the Stage of Change Designation.
