Momentary Affect Influences Young Adults' Simultaneous Alcohol and Marijuana Use Decisions

A recent study examining the role of affect in young adults' willingness to engage in simultaneous alcohol and marijuana (SAM) use reveals significant findings. Researchers from George Washington University conducted two within-subjects, scenario-based studies to investigate the impact of momentary affect on SAM use decisions. The studies involved a total of 382 participants, including college students and young adults from Black, Hispanic, and Multiracial backgrounds. The findings suggest that momentary affect, particularly feeling excited/confident, has a significant influence on young adults' willingness to engage in SAM use.

Key Takeaways:

  • The study found that young adults anticipated a greater willingness to engage in SAM use when they imagined feeling confident/excited and in the affect absent scenario, compared to when feeling anxious/uncertain.
  • Willingness ratings in the confident/excited scenario did not differ from the affect absent scenario.
  • Abstainers reported the greatest willingness when feeling confident/excited, followed by affect absent, and reported the lowest willingness when feeling anxious/uncertain.
  • Experimental and experienced marijuana users showed a lower willingness to engage in SAM use when feeling anxious/uncertain compared to feeling confident/excited and affect absent.
  • The study concluded that momentary affect has a significant influence on SAM use decisions via the socially reactive pathway of information processing, with important implications for future prevention and intervention efforts.
  • The findings have significant implications for the development of prevention and intervention strategies targeting young adults' SAM use behaviors.

Statistics:

  • The study involved 212 participants in Study 1 and 170 participants in Study 2.
  • The participants reported varying histories of lifetime marijuana use, with some reporting no history of use and others reporting experimental or experienced use.
  • The participants reported a greater willingness to engage in SAM use when feeling excited/confident and in the affect absent scenario, compared to when feeling anxious/uncertain.
  • Willingness ratings in the confident/excited scenario did not differ from the affect absent scenario.
