Experience sampling self-reports of social media use have comparable predictive validity to digital trace measures.

Research agrees that self-reported measures of time spent with social media (TSM) show poor convergent validity, because they correlate modestly with equivalent objective digital trace measures. This experience sampling study among 159 adolescents (12,617 self-reports) extends this work by examining the comparative predictive validity of self-reported and digital trace measures of TSM, that is, the extent to which self-reported and digital trace measures of TSM correspond in their effects on self-esteem, well-being, and friendship closeness. Using an N = 1 method of analysis, we investigated the correspondence on a between-person, within-person, and person-specific level.

Older workers' plans for activities in retirement: The role of opportunities, spousal support, and time perception.

Retirement is a major life-course transition for which some people plan more than others. Given that planning positively affects retirement adjustment, it is important to investigate the heterogeneity in retirement planning and its antecedents. While financial preparation has been thoroughly investigated, little is known about the activities older workers plan to do in retirement.
