Past research regarding parental communication and risk-taking behaviors largely focuses on risk-taking behaviors happening during adolescence, more specifically, the focus has largely been on sexual risk-taking behaviors. The current research examines this relationship of quality parental communication and risk-taking behaviors but shifts the focus to risk-taking behaviors happening in a different developmental period—emerging adulthood. The risk-taking behaviors examined in the present study are risky drinking behaviors, such as binge drinking and the risktaking behavior of vaping, as they have not been extensively researched in the past. The present study’s objective was to determine whether quality parental communication happening during adolescence would be related to risk-taking behaviors happening in emerging adulthood. Specifically, it was hypothesized that quality parent-adolescent communication would have a negative relationship with both alcohol use and the use of electronic cigarettes during emerging adulthood. Participants completed measures of parent-adolescent communication as well as measures regarding their current drinking and vaping habits and correlation and regression analysis were conducted. The results of these analysis indicated that quality parental communication during adolescence had a significant negative correlation with alcohol use in emerging adulthood, but no correlation was found for quality parental communication and vaping habits.
