摘要：Collaborators from 32 academic institutions primarily in the United States collected data from emerging adults (N'raw''' = 4220, N'processed' = 3134). Participants completed self-report measures assessing markers of adulthood, IDEA inventory of dimensions of emerging adulthood, subjective well-being, mindfulness, belonging, self-efficacy, disability identity, somatic health, perceived stress, perceived social support, social media use, political affiliation, beliefs about the American dream, interpersonal transgressions, narcissism, interpersonal exploitativeness, beliefs about marriage, and demographics. The data are available at (https://osf.io/qtqpb/) with details about the study and contributors at our main EAMMi2 page (https://osf.io/te54b/). These data may be used to examine new research questions, provide authentic research experiences for students, and provide demonstrations for research and statistics courses.
