Within a positive youth development framework, Lerner and colleagues posited that youth and young adults are societal assets that support the pillars of democracy and incite community contribution through the development of individual character strengths. Strengths might include hope and civic attitudes, which researchers have linked to numerous positive outcomes; however, connections to civic behaviors are largely unknown. Developmentally, shifting identities, excitement about the future, and an introduction into formal citizenship within U.S. society characterize the emerging adulthood period. Emerging adulthood is also characterized by burgeoning relationships and service opportunities, particularly on college campuses. These factors make emerging adulthood a prime context in which to investigate the aims of the current study, which centered on investigation of the development of hope and civic attitudes, and how each contributed to civic engagement including interpersonal prosocial behavior, community volunteering, and political behaviors. Effortful control was hypothesized to play a role in relations as an intrapersonal factor that implicated relations between hope and civic attitudes and outcomes, and was therefore included as a moderator. Sample consisted of 217 emerging adults (~ 67% female, 58% White, 30% Pell-grant eligible, 19-20 years old) across three time points at a major university in the southwest U.S. from spring 2019 to spring 2020. Path models, structural equation models, and moderation analyses evidenced direct relations between hope and interpersonal prosocial behavior. Civic attitudes directly related to community volunteering and political engagement. Transactional relations between hope and civic engagement were not apparent. Similarly, moderation analyses showed no interactive effects between hope and civic attitudes and effortful control on study outcomes. Findings evidenced stability in hope and civic attitudes across early emerging adulthood and invited future work investigating the development of each in early adolescence and later emerging adulthood. Future interventions might prioritize the development of hope in efforts to increase interpersonal prosociality and civic attitudes to increase volunteering and political engagement among emerging adults, where civic engagement has been historically low. Overall, findings supported hope and civic attitudes as hallmarks of positive youth development with the potential to uniquely contribute to community enhancement in emerging adulthood.
