• Effects of Racial Discrimination on Stress, Negative Emotions, and Alcohol Craving: A Registered Report of a Virtual Reality Experiment

    stage 2

    Objectives: Racial discrimination experiences contribute to health disparities and can influence individuals’ health. Yet, pathways by which discrimination-related experiences affect alcohol craving remain understudied using experimental designs. Additionally, limited research has examined possible differential effects of “major” discrimination and microaggression experiences in everyday life on alcohol craving. This between-groups experiment examined causal effects of everyday racial discrimination on stress, negative emotions, and alcohol craving. We also tested indirect pathways by which discrimination-related experiences were linked to alcohol craving via stress and negative emotions. Method: People of color and Indigenous peoples participated in the study (N=184; Mage=23.90; 47.8% women; 48.9% community adults). Participants were randomized to one of four experimental conditions, in which they experienced in virtual environments either “major” discrimination, microinsult, microinvalidation, or daily hassles unrelated to race/racism. Participants’ levels of stress, negative emotions, and alcohol craving were assessed immediately before and after experimental simulations. Results: Compared to daily hassles unrelated to race/racism, simulated racial discrimination elicited greater stress and negative emotions. Daily hassles caused greater alcohol craving among those who endorsed higher levels of coping motives for drinking. We observed minimal differences in stress and negative emotions across the three racial discrimination conditions, and found no evidence supporting indirect links between racial discrimination and alcohol craving via stress and negative emotions. Conclusion: Everyday racial discrimination—regardless of intensity level—is more stressful than daily hassles unrelated to race/racism. Future research should examine cumulative effects of racial discrimination, and understanding individual difference factors that moderate its immediate and delayed effects.

  • An experimental investigation of daily mental contrasting with implementation intentions and goal motives in reducing bedtime procrastination: a registered report

    Objectives Mental contrasting with implementation intentions (MCII) is an effective self-regulation strategy for goal pursuit. Although it is a quick and cost-effective strategy, most of its applications have consisted of single-time training. Building on the existing research on bedtime procrastination, we propose that daily MCII applications can lead to more efficient pursuit of bedtime goals. Furthermore, we evaluate the conditions where MCII training could be more advantageous for people with different types of goal motives. Methods and Measures We recruited 297 participants via Prolific and randomly allocated participants into either daily MCII or single MCII groups for a week-long diary study. We measured goal motives, goal-regulatory variables, bedtime procrastination, and affect to test our hypotheses. We conducted a multilevel structural equation modelling using Mplus. Results Participants who completed MCII daily reported less bedtime procrastination than individuals who performed MCII one-off at the start of the week. Participants experienced increased positive affect and decreased negative affect when they procrastinated less. Autonomous goal motives were not associated with bedtime procrastination. Discussion Daily MCII appears as an effective and easy-to-implement strategy helps reducing bedtime procrastination. Future research should test the effectiveness of daily MCII in other contexts.
