Do you or your friend struggle with self-confidence? Help us research how close friends talk and support each other! If you AND one of your close friends are between 18 and 40 years and willing to participate together, you may be eligible. You and your friend can EACH earn up to $177.5. For this non-treatment, non-medication research study, you and one of your close, same-sex friends will participate together at Northwestern’s medical school campus in downtown Chicago. You will complete an interview, a variety of questionnaires, and several tasks with your friend while having your brain activity recorded using EEG. Many of the procedures will be completed online rather than in person. This study will take approximately 5.5 hours to complete, splitting into 2 days. In addition, you will complete a brief online survey every 2 weeks for 3 months (6 surveys in total). You and your friend will each be paid $25/hour for a total of $177.5 (the total amount will depend on how long your visit takes). Additionally, you will also be compensated for parking or CTA travel for attending the study visit. If you are interested, please fill out this brief survey to see if you are eligible (https://redcap.nubic.northwestern.edu/redcap/surveys/?s=487MNAJAMWMLC9AM). Want more information?
