Stability and Instability of Subjective Well-Being in the Transition from Adolescence to Young Adulthood: Longitudinal Evidence from 20991 Young Australians.

Purpose: This study assessed the long-term stability and instability of subjective well-being during post-school transition (i.e., transition from adolescence to young adulthood) and evaluated the determinants of transition stability.

Developmental investigation of the domain-specific nature of the life satisfaction construct across the post-school transition.

This study evaluated the nature of the life satisfaction construct with an emphasis on the comparison between a global or domain-specific operationalization during the transition from adolescence to adulthood. A combination of person-centered and variable-centered methods were used to analyze 7 waves of data covering the postschool transition from a sample of 24,721 youth participating in Longitudinal Study of Australian Youth (LSAY) between 1998 and 2010. Evidence for the increasing importance of a domain-specific approach as adolescents entered adulthood was provided by: (1) factor analyses identifying a 3-factor model covering achievement, family, and leisure satisfaction that proved invariant across time waves; (2) factor mixture analyses showing shape-related differences between profiles (i.
