Outcome Measures

Primary Outcomes (1)

  • Parent-reported adherence to lethal means restriction (LMR)

    Change in parental adherence to lethal means restriction practices will be assessed using the Parent Adherence to Lethal Means Restriction (PA-LMR), a structured parent-report survey measuring adherence to multiple lethal means restriction behaviors. Items are rated on a Likert scale, with total scores ranging from 11 to 55; higher scores indicate greater adherence.

    Baseline to 6 weeks

Secondary Outcomes (1)

  • Adolescent Perceived Access to Lethal Means

    Baseline to 6 weeks

Other Outcomes (1)

  • Exploratory Outcome

    Baseline to 12 weeks

EXPERIMENTAL

Thrice-weekly direct text messages encouraging Lethal Mean Restriction practices and suicide risk statistics to recalibrate parental risk perception
