“…By longitudinally following a sample of EEA into MEA (possibly extending the sample also to include late EA, 26–29 years), researchers would be able to understand the sequential path from friend support initially predicting commitment, satisfaction, and quality of alternatives in the early years of EA to parental support predicting commitment, satisfaction, and investments in the middle years of EA.
