PRIMARY OBJECTIVES:
I. Evaluate OSU graduate students' ONP use patterns, perceptions of use within their social circles, and ONP information-gathering behaviors on social media.
II. Test the effects of normative-focused, YA-directed ONP risk messages to enhance knowledge and correct misperceptions about addiction.
III. Estimate the effect of dynamic versus (vs.) static visual ONP risk messages on YA's information-sharing intentions.
OUTLINE: All participants will first complete Aim 1. Participants identified as high risk for nicotine dependence and who consent to follow up will then be randomly assigned to Aim 2 or Aim 3.
AIM 1: Participants complete an online survey assessing ONP use patterns, perceptions of ONP-related norms, and interactions with ONP content on social media over 5-10 minutes on study.
AIM 2: Participants view four intervention messages shown in a randomized order. These messages are randomly selected from five message blocks, which are part of a total pool of 33 messages. After viewing each message, participants complete a brief questionnaire that assesses perceived message effectiveness, ONP-related knowledge, risk perceptions, and self-efficacy.
AIM 3: Participants are randomly assigned to 1 of 2 conditions.
CONDITION I: Participants view static visual ONP risk messages on study.
CONDITION II: Participants view dynamic visual ONP risk messages on study.
Following message exposure, participants will answer questions about their intentions to use ONPs in the future, perceived susceptibility, beliefs, attitudes toward ONPs, and cognitive responses (e.g., perceived message effectiveness).
