Background: Drinking identity (the extent to which one links the self with drinking alcohol) is a unique risk factor for college students' hazardous drinking that is not directly targeted by existing interventions. We conducted a study that aimed to decrease drinking identity among college students with hazardous drinking. We adapted a writing task about the future self and tested whether three writing sessions could decrease drinking identity and change drinking. We also investigated whether two additional factors (writing perspective and inclusion of participants' social networks) would enhance task impact. The present study evaluated whether posited proximal cognitive and motivational outcomes (drinking identity, self‐efficacy, readiness to change, and drinking intentions) changed immediately after each writing session. Method: The study is a randomized clinical trial in which hypotheses and analyses were pre‐registered. Participants were 328 college students who met hazardous drinking criteria. The study had a 2 (narrative writing topic: low‐risk drinker vs. reduced smartphone use) × 2 (writing perspective: first‐person vs. non‐first‐person) × 2 (social network instruction: instructed to include vs. not) factorial design. Proximal outcomes were drinking identity, self‐efficacy, readiness to change, and drinking intentions. The clinical outcome was alcohol consumption. Participants completed three laboratory sessions at weekly intervals that included the writing task and pre‐ and post‐task assessments. Results: Results were largely null, except that readiness to reduce drinking was higher in the low‐risk drinker condition and increased over the lab sessions. Time effects indicated that reductions in drinking identity, drinking intentions, and alcohol consumption, and increases in self‐efficacy were observed but did not change above and beyond control conditions. Conclusions: Findings indicate the need to strengthen the writing task and select a more appropriate control task to target proposed proximal outcomes. Future studies might try personalizing the task, evaluating its efficacy with individuals motivated to change their drinking, and using a control task that does not involve imagining a future self.

Research suggests that placebos administered without deception (i.e. non‐deceptive placebos) may provide an effective and low‐effort intervention to manage stress and improve mental health. However, whether non‐deceptive placebos administered remotely online can manage distress for people at risk for developing high levels of affective symptoms remains unclear. Volunteers experiencing prolonged stress from the COVID‐19 pandemic were recruited into a randomized controlled trial to examine the efficacy of a non‐deceptive placebo intervention administered remotely online on affective outcomes. COVID‐related stress, overall stress, anxiety, and depression were assessed at baseline, midpoint, and endpoint. Compared with the control group, participants in the non‐deceptive placebo group reported significant reductions from baseline in all primary affective outcomes after 2 weeks. Additionally, participants in the non‐deceptive placebo group found the intervention feasible, acceptable, and appropriate for the context. Non‐deceptive placebos, even when administered remotely online, offer an alternative and effective way to help people manage prolonged stress. Future large‐scale studies are needed to determine if non‐deceptive placebos can be effective across different prolonged stress situations and for clinical populations. [ABSTRACT FROM AUTHOR]
