Role of Self-Worth Contingencies on Sleep Quality Due to Discrimination and Depressive Symptoms

Role of Self-Worth Contingencies on Sleep Quality Due to Discrimination and Depressive Symptoms Victoria Cambar, Depts. of Psychology and Criminal Justice, Ruth Laryea, and Bianca Owens and Chelsie Dunn, Dept. of Psychology Graduate Students, with Dr. Kristina Hood, Dept. of Psychology Scholars have well documented the association on discrimination experiences, negative implications for both physical and psychological symptoms (Gee et al., 2007; Williams et al., 2008). According to Stone and Carlisle (2018), the experience of racial discrimination at the workplace may increase the likelihood of negative emotions and sadness. In addition, the occurrence of perceived discrimination experienced by African American undergrad students in college settings has been associated with psychological and emotional problems including depression (Chao, Mallinckrodt, & Wei, 2012). Subtle forms of discrimination in both the school and the workplace are predictors of negative physical health conditions like low energy levels and fatigue (Nadal et al., 2017). A notable variable that may play an influential role in the relationship between discrimination and depressive symptoms is one’s self-worth; but more specifically their self-worth contingencies. Such that, self-worth may also play a role in the link between discrimination and depression. Orth and Robins (2013) suggest that individuals with low self-esteem/worth are more likely to feel sad, lonely, and dejected. Contingent self-worth, the fluctuation of one’s self-worth in response to positive or negative experiences including the perceived approval or lack thereof of peers, has also shown to be a vulnerability factor for depression and depressive symptoms (Crocker & Knight, 2005; Crocker et al., 2003). According to Zahn and colleagues (2015) low self-worth and feelings of worthlessness, often appear to occur consistently with lack of energy. Therefore, the present study sought to examine the moderating role of contingent self-worth (i.e., others’ approval) on the link between experiences of discrimination at work or school and depressive symptoms after controlling for age, frequency of gendered racial discriminatory experiences, and gendered racial socializations. The current study consisted of 206 Black/African American women between the ages of 18 and 55 (M=33.24, SD=8.46). Majority of the sample was employed (97%) and about 30% were enrolled in a two- or four-year university. Participants were recruited from Amazon Mechanical Turk and completed questions assessing their sleep quality due to discrimination, depressive symptoms (i.e., energy and emotion levels), and self-worth contingencies (i.e., self-worth based on others’ approval). The moderation model was assessed via the PROCESS macro (Hayes, 2017) within SPSS v.26 using 5,000 bootstrapped samples. Moderation analysis revealed a statistically significant interaction between sleep quality due to discrimination and others’ approval-contingent self-worth on depressive symptoms (i.e., energy and emotions), b=-.07,SE=.04, 95% CI [-.14, -.01], p=.04. To interpret the statistically significant moderation effect, we used Hayes’s PROCESS v.3 (2017) Johnson-Neyman and bootstrap analysis. Findings revealed that others’ approval-contingent self-worth is a significant moderator of the link between sleep quality due to discrimination and depressive symptoms at higher levels of self-worth contingencies only (b=-.20,SE=.07, 95% CI [-.33, -.06], p=.00). More specifically, among those who higher self-worth contingencies, those who reported poor sleep quality due to discrimination reported greater depressive symptoms compared to those with better sleep quality. Findings could potentially enhance existing mental health interventions by increasing awareness of how discriminatory events impact sleep quality and depressive symptoms.https://scholarscompass.vcu.edu/uresposters/1301/thumbnail.jp

The Illusion of Parent Choice: Lessons Learned from BPCs Parent Survey Series

In October 2019, BPC conducted its first national survey of parents in hopes of learning, "Do parents prefer child care closer to home or work?" We wanted to know how finding child care (the supply) impacts parents and their choices. Our first survey revealed parents prefer child care closer to home, but our survey raised more questions. Why do parents choose certain child care arrangements? What factors are most important to parents?As BPC set to investigate in early 2020, the pandemic shifted our focus to COVID-19's impact on child care, including closures, increased safety measures, and how remote work impacted the need for child care

Precision Timing of Two Anomalous X-Ray Pulsars

We report on long-term X-ray timing of two anomalous X-ray pulsars, 1RXS J170849.0-400910 and 1E 2259+586, using the Rossi X-ray Timing Explorer. In monthly observations made over 1.4 yr and 2.6 yr for the two pulsars, respectively, we have obtained phase-coherent timing solutions which imply that these objects have been rotating with great stability throughout the course of our observations. For 1RXS J170849.0-400910, we find a rotation frequency of 0.0909169331(5) Hz and frequency derivative -15.687(4) x 10^(-14) Hz/s, for epoch MJD 51215.931. For 1E 2259+586, we find a rotation frequency of 0.1432880613(2)Hz, and frequency derivative -1.0026(7) x 10^(-14) Hz/s, for epoch MJD 51195.583. RMS phase residuals from these simple models are only about 0.01 cycles for both sources. We show that the frequency derivative for 1E 2259+586 is inconsistent with that inferred from incoherent frequency observations made over the last 20 yr. Our observations are consistent with the magnetar hypothesis and make binary accretion scenarios appear unlikely.Comment: 12 pages including 3 figures. To appear in ApJ Letter

The high-temperature rotation-vibration spectrum and rotational clustering of silylene (SiH2_2)

A rotation-vibration line list for the electronic ground state ($\tilde{X}^{1}A_{1}$) of SiH$_2$ is presented. The line list, named CATS, is suitable for temperatures up to 2000 K and covers the wavenumber range 0 - 10,000 cm$^{-1}$(wavelengths $>1.0$ $\mu$m) for states with rotational excitation up to $J=52$. Over 310 million transitions between 593 804 energy levels have been computed variationally with a new empirically refined potential energy surface, determined by refining to 75 empirical term values with $J\leq 5$ and a newly computed high-level ab initio dipole moment surface. This is the first, comprehensive high-temperature line list to be reported for SiH$_2$ and it is expected to aid the study of silylene in plasma physics, industrial processes and possible astronomical detection. Furthermore, we investigate the phenomenon of rotational energy level clustering in the spectrum of SiH$_2$. The CATS line list is available from the ExoMol database (www.exomol.com) and the CDS database

Effects of Mavacamten on Measures of Cardiopulmonary Exercise Testing Beyond Peak Oxygen Consumption: A Secondary Analysis of the EXPLORER-HCM Randomized Trial

IMPORTANCE: Mavacamten, a cardiac myosin inhibitor, improved peak oxygen uptake (pVO2) in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM) in the EXPLORER-HCM study. However, the full extent of mavacamten's effects on exercise performance remains unclear. OBJECTIVE: To investigate the effect of mavacamten on exercise physiology using cardiopulmonary exercise testing (CPET). DESIGN, SETTING, AND PARTICIPANTS: Exploratory analyses of the data from the EXPLORER-HCM study, a randomized, double-blind, placebo-controlled, phase 3 trial that was conducted in 68 cardiovascular centers in 13 countries. In total, 251 patients with symptomatic obstructive HCM were enrolled. INTERVENTIONS: Patients were randomly assigned in a 1:1 ratio to mavacamten or placebo. MAIN OUTCOMES AND MEASURES: The following prespecified exploratory cardiovascular and performance parameters were assessed with a standardized treadmill or bicycle ergometer test protocol at baseline and week 30: carbon dioxide output (VCO2), minute ventilation (VE), peak VE/VCO2 ratio, ventilatory efficiency (VE/VCO2 slope), peak respiratory exchange ratio (RER), peak circulatory power, ventilatory power, ventilatory threshold, peak metabolic equivalents (METs), peak exercise time, partial pressure of end-tidal carbon dioxide (PETCO2), and VO2/workload slope. RESULTS: Two hundred fifty-one patients were enrolled. The mean (SD) age was 58.5 (11.9) years and 59% of patients were male. There were significant improvements with mavacamten vs placebo in the following peak-exercise CPET parameters: peak VE/VCO2 ratio (least squares [LS] mean difference, -2.2; 95% CI, -3.05 to -1.26; P < .001), peak METs (LS mean difference, 0.4; 95% CI, 0.17-0.60; P < .001), peak circulatory power (LS mean difference, 372.9 mL/kg/min × mm Hg; 95% CI, 153.12-592.61; P = .001), and peak PETCO2 (LS mean difference, 2.0 mm Hg; 95% CI, 1.12-2.79; P < .001). Mavacamten also improved peak exercise time compared with placebo (LS mean difference, 0.7 minutes; 95% CI, 0.13-1.24; P = .02). There was a significant improvement in nonpeak-exercise CPET parameters, such as VE/VCO2 slope (LS mean difference, -2.6; 95% CI, -3.58 to -1.52; P < .001) and ventilatory power (LS mean difference, 0.6 mm Hg; 95% CI, 0.29-0.90; P < .001) favoring mavacamten vs placebo. CONCLUSIONS AND RELEVANCE: Mavacamten improved a range of CPET parameters beyond pVO2, indicating consistent and broad benefits on maximal exercise capacity. Although improvements in peak-exercise CPET parameters are clinically meaningful, the favorable effects of mavacamten on submaximal exertional tolerance provide further insights into the beneficial impact of mavacamten in patients with obstructive HCM.

The cellular and synaptic architecture of the mechanosensory dorsal horn

The deep dorsal horn is a poorly characterized spinal cord region implicated in processing low-threshold mechanoreceptor (LTMR) information. We report an array of mouse genetic tools for defining neuronal components and functions of the dorsal horn LTMR-recipient zone (LTMR-RZ), a role for LTMR-RZ processing in tactile perception, and the basic logic of LTMR-RZ organization. We found an unexpectedly high degree of neuronal diversity in the LTMR-RZ: seven excitatory and four inhibitory subtypes of interneurons exhibiting unique morphological, physiological, and synaptic properties. Remarkably, LTMRs form synapses on between four and 11 LTMR-RZ interneuron subtypes, while each LTMR-RZ interneuron subtype samples inputs from at least one to three LTMR classes, as well as spinal cord interneurons and corticospinal neurons. Thus, the LTMR-RZ is a somatosensory processing region endowed with a neuronal complexity that rivals the retina and functions to pattern the activity of ascending touch pathways that underlie tactile perception
