This document summarizes an ongoing research study testing the impact of online brain training in promoting wellbeing and resilience. The study involves: 1) Recruiting 1600 twins aged 18-65 years from the Australian Twin Registry to complete web assessments and cognitive/brain imaging tests. 2) Testing the efficacy of the brain training program MyBrainSolutions over 30 days in improving psychological functioning such as positive affect, depressed mood, emotion suppression and social skills. 3) Developing new measures of wellbeing and resilience for use in research cohorts, such as the COMPAS-W wellbeing scale and Gatt Resilience Scale, and seeking collaborators interested in testing e-health platforms or using the new scales
