Developmental stasis, sensitivity, and disturbance: Linking concepts to analytic methods using impulsivity and alcohol use.

The goals of this article are to (a) describe and contrast conceptual characteristics of periods of developmental sensitivity, disturbance, and stasis, and (b) translate these concepts to testable analytic models with an example dataset. Although the concept of developmental sensitivity is widely known, the concepts of developmental stasis and disturbance have received less attention. We first define the concepts and their principles and then, using repeated measures data on impulsivity and alcohol use from adolescence to young adulthood, propose the dual latent change score (LCS) growth model as one analytic approach for evaluating evidence for key characteristics of these developmental concepts via examination of intraindividual time-varying associations.

Socioeconomic Disparities, Nighttime Bedroom Temperature, and Children's Sleep.

We investigated associations between family income-to-needs, nighttime bedroom temperature (NBT), and children's sleep. Using a sample of 46 children (M age = 11.5), we recorded NBT and objective sleep parameters via actigraphy nightly for one week to evaluate within- (night-to-night) and between-person associations. We found consistent evidence for a curvilinear association between NBT and sleep variables at the between-person level, indicating that children who slept in rooms that were "too hot" or "too cold" experienced poorer sleep. Moreover, children in lower income-to-needs families had more extreme NBTs. There was some evidence that family income-to-needs is indirectly related to sleep via NBT, but with interpretational caveats. These findings point to NBT as a potentially modifiable variable, which has implications for practical applications to mitigate effects of socioeconomic disparities on children's sleep.

Experiences of Sexual Assault and Financial Stability: Sense of Control as a Potential Mechanism.

This investigation utilized the Midlife in the United States Survey (N = 3,258) to assess the relationships between sexual assault, sense of control, and financial stability. Age of first sexual assault and sexual assault revictimization were also considered in analyses of sexual assault survivors' data. Results revealed consistent associations between experiences of sexual assault and revictimization with lower financial stability and suggest that sense of control may be an indirect mechanism linking these variables. Findings have policy relevance and practical implications for practitioners. Restoring sexual assault victims' internal loci of control may promote more positive financial outcomes.
