Development of subjective well-being and its relationship with self-esteem in early adolescence

Despite evidence indicating that self-esteem (SE) may be considered a precondition to subjective well-being (SWB), there are inconclusive findings regarding its developmental links with SWB. Considering the declines in SWB, the purpose of this study is to examine the developmental changes in SWB and its relationship with SE in early adolescence. The data of 11,231 adolescents aged 11 and 14 years old (50% females) from the Millennium Cohort Study were utilized. Latent mean comparison indicated that SWB declined substantially between 11 and 14 years old in the United Kingdom. Cross-lagged modelling showed that SWB was developmentally unstable and that SE predicted later changes in SWB, whereas SWB did not predict changes in SE. SWB declines in the United Kingdom are mostly linked to less satisfaction with secondary school contexts and peer relationships. In short, SE is an important factor that can contribute to adolescents' SWB. Implications for educational policy and practice are discussed.
