Implementing educational interventions at this age can instill healthy behaviors and prevent risky behaviors in adulthood. Accordingly, the present study was conducted with the aim of implementing a campaign to prevent alcohol misuse among parents of children aged 3–7 years in Kerman Province, Iran.</span></span></span></span><br> <span style=font-size:12pt><span style=line-height:normal><span style=font-family:Aptos,serif><b><span new= roman= style=font-family: times=>Methods:</span></b><span new= roman= style=font-family: times=> This study was carried out on 500 participants in the pretest and 497 participants in the posttest between November 2023 and January 2024 in Kerman.
