Evaluating Convergence of Within-Person Change and Between-Person Age Differences in Age-Heterogeneous Longitudinal Studies.
The distinction of between-person age differences from within-person age changes is necessary for understanding aging-related change processes. Although longitudinal studies are required to address issues relating to within person change, most studies begin using age-heterogeneous samples and conclude using survival-heterogeneous samples. Given the numerous potential confounds associated with a...
متن کاملWithin-person variability in state anxiety across adulthood: Magnitude and associations with between-person characteristics.
Across domains of functioning, research has shown substantial within-person variability in a number of different types of variables from one measurement occasion to another. Using data obtained from a large sample (n = 784, 18-97 years) at three separate occasions, we examined properties and correlates of short-term variability in a construct that by definition is prone to fluctuations, namely ...
متن کاملThe disaggregation of within-person and between-person effects in longitudinal models of change.
Longitudinal models are becoming increasingly prevalent in the behavioral sciences, with key advantages including increased power, more comprehensive measurement, and establishment of temporal precedence. One particularly salient strength offered by longitudinal data is the ability to disaggregate between-person and within-person effects in the regression of an outcome on a time-varying covaria...
متن کاملPersons as Contexts: Evaluating Between-Person and Within-Person Effects in Longitudinal Analysis
Relationships among multiple variables over time are of interest in many developmental areas and are frequently examined using time-varying predictors in multilevel models. Yet an incomplete specification of time-varying predictors will usually result in biased model effects. Specifically, the impact of constant, between-person sources of variation must be differentiated from the impact of time...
متن کاملWithin-person relationships between mood and creativity.
State mood has been proposed as a facilitator of creative behavior. Whereas positive mood compared to neutral mood generally facilitates creative performance, mood effects are weaker and less consistent when positive mood is compared to negative mood. These inconsistent results may be due to focusing only on mood valence, while neglecting or confounding mood activation. The current study is bas...
