Brief Summary

This is a one-arm pilot study testing the feasibility and acceptability of a decision aid about safe firearm storage.

Conditions

Dementia, Mild; Depression

Outcome Measures

Primary Outcomes (1)

• Number of Participants With Any Improvement in Safe Firearm Storage (Adapted From the National Firearm Survey)

  Data were reported on an ordinal scale (0=unlocked and loaded; 1=unlocked and unloaded; 2=locked and loaded; 3=locked and unloaded; 4=removed from house). Any improvement on the ordinal scale from baseline to follow-up was dichotomized (0=no improvement; 1=any improvement in safe firearm storage).

  Assessed at 4 weeks post enrollment

Secondary Outcomes (4)

• Change From Baseline in the Low-Literacy Decisional Conflict Scale Score

  Assessed at 4 weeks post enrollment

• Change From Baseline in Firearm Safe Storage Knowledge Questionnaire Score

  Assessed at 4 weeks post enrollment

• Number of Participants Who Access the Intervention

  Assessed at 4 weeks post enrollment

• Mean Score on the Acceptability of Intervention Measure

  Assessed at 4 weeks post enrollment
