Comparison Of Cortisol Samples In The First Two Weeks Of Life In Preterm Infants, Tiffany A. Moore, Kendra K. Schmid, Jeffrey French

Psychology Faculty Publications

Background: Growing literature on negative childhood stress emphasizes the need to understand cortisol values from varying biomarker samples.

Objective: This work aimed to examine cortisol samples for usability, associations, and individual stability in neonates.

Subjects: The sample consisted of preterm infants (n=31).

Materials and methods: Analyses on cortisol collected from cord blood and from saliva and urine samples on days 1, 7, and 14 included Spearman correlations and paired t-tests.

Results: Usability rates were 80.6% (cord blood), 85.9% (saliva), and 93.5% (urine). Salivary and urinary cortisol levels had significant correlation on day 1 only (p=0.004). Significant differences in individual stability …

Stability And Change: Stress Responses And The Shaping Of Behavioral Phenotypes Over The Life Span, Michael B. Hennessy, Sylvia Kaiser, Tobias Tiedtke, Norbert Sachser

Psychology Faculty Publications

In mammals, maternal signals conveyed via influences on hypothalamic-pituitary-adrenal (HPA) activity may shape behavior of the young to be better adapted for prevailing environmental conditions. However, the mother's influence extends beyond classic stress response systems. In guinea pigs, several hours (h) of separation from the mother activates not only the HPA axis, but also the innate immune system, which effects immediate behavioral change, as well as modifies behavioral responsiveness in the future. Moreover, the presence of the mother potently suppresses the behavioral consequences of this innate immune activation. These findings raise the possibility that long-term adaptive behavioral change can be …

Five Facets Of Mindfulness And Psychological Health: Evaluating A Psychological Model Of The Mechanisms Of Mindfulness, David B. Brown, Adrian J. Bravo, Corey R. Roos, Matthew R. Pearson

Psychology Faculty Publications

There has been an increasing focus on determining the psychological mechanisms underlying the broad effects of mindfulness on psychological health. Mindfulness has been posited to be related to the construct of reperceiving or decentering, defined as a shift in perspective associated with decreased attachment to one's thoughts and emotions. Decentering is proposed to be a meta-mechanism that mobilizes four psychological mechanisms (cognitive flexibility, values clarification, self-regulation, and exposure), which in turn are associated with positive health outcomes. Despite preliminary support for this model, extant studies testing this model have not examined distinct facets of mindfulness. The present study used a …
