Ecological Momentary Assessment (EMA) is a data collection method that repeatedly measures real-time data about a subject to understand how individuals behave in their natural environment and identify the factors that may drive or inhibit them (Shiffman Et al., 2008). There has been little research on the effects of everyday microaggressions on sexual and gender minority (SGM) youth of color tobacco use, research has mostly focused on outward discriminatory behavior or victimization. We aimed to investigate whether an EMA design is feasible to study the extent to which daily microaggressions influence e-cigarette use in SGM youth of color. This study allows for further investigation on the topic to be done, which will supplement an already existing body of knowledge on the topic of minority stress theory and how that relates to risk behaviors. Participants (N=8) were instructed to wear a smart ring for at least 16 hours a day while completing three surveys a day for the study duration of three days. We found that an EMA design was successful in this context as most participants completed all daily surveys. Cigarette use was correlated with the racial microaggressions scale score, the bivariate correlation between cigarette use and racial microaggression at baseline was significant (r = 0.68, p = .02). This was interpreted that participants most likely used smoking as a tool to cope with stress. Due to the small sample size, further studies need to be conducted to further cement this finding. However, we felt that these results showed that the study has great potential to produce great findings as we investigate further.
