Person-Specific Methods for Characterizing the Course and Temporal Dynamics of Concussion Symptomatology: A Pilot Study.

Better characterization of acute concussion symptomatology is needed in order to advance clinical and scientific understanding of persistent concussion symptoms. This paper aims to illustrate a novel framework for conceptualizing, collecting, and analyzing concussion symptom data. To that end, we describe the temporal and structural dynamics of acute concussion symptoms at the individual-patient level. Ten recently concussion adolescents and young adults completed 20 days of ecological momentary assessment (EMA) of post-concussion symptoms. Follow-up assessments were completed at 3 months post-injury. Network modeling revealed marked heterogeneity across participants. In the overall sample, temporal patterns explained the most variance in light sensitivity (48%) and the least variance in vomiting (5%). About half of the participants had symptom networks that were sparse after controlling for temporal variation. The other individualized symptom networks were densely interconnected clusters of symptoms. Networks were highly idiosyncratic in nature, yet emotional symptoms (nervousness, emotional, sadness), cognitive symptoms (mental fogginess, slowness), and symptoms of hyperacusis (sensitivity to light, sensitivity to noise) tended to cluster together across participants. Person-specific analytic techniques revealed a number of idiosyncratic features of post-concussion symptomatology. We propose applying this framework to future research to better understand individual differences in concussion recovery

IDENTIFYING MCMI-IV PERSONALITY DISORDER SUBGROUPS USING EXPLORATORY FACTOR ANALYSIS AND LATENT CLASS ANALYSIS

Patients diagnosed with personality disorders (PDs) have higher morbidity and mortality rates than those without PDs. The DSM-5 PD diagnoses and the cluster system lack a theoretical and empirical basis, which hinders the development of knowledge about PDs and interventions for PDs. This present study attempts to add to this literature by forming PD groups using a combination of exploratory factor analysis (EFA) and latent class analysis (LCA) based on PD scores from the Millon Clinical Multiaxial Inventory-IV (MCMI-IV), a method recommended by Gorman and Primavera (1983). Participants were 251 English speaking males and females ages 18 to 75 seeking outpatient psychotherapy at a private non-profit clinic. The EFA yielded a four-factor model of the MCMI-IV, and the factors can be described as Neuroticism, Antagonism, Extraversion vs. Introversion, and Compulsivity vs. Defiance factors. The results of the LCA suggest a five-class solution, with classes that can be labeled Neuroticism, Antagonism, Depression and Anxiety, No PD, and Extraversion classes, which were then compared on MCMI-IV personality, clinical, and Grossman Facet scales. Latent classes and factors were matched on some PD scales, but there were also some notable differences. Future research directions are discussed

Performing the Testimonial: Rethinking Verbatim Dramaturgies

Responding to the resurgence of verbatim theatre that emerged in Britain, Australia, the United States and other parts of the world in the early 1990s, this book offers one of the first sustained, critical engagements with contemporary verbatim, documentary and testimonial dramaturgies. Offering a new reading of the history of the documentary and verbatim theatre form, the book re-locates verbatim and testimonial theatre away from discourses of the real and representations of reality and instead argues that these dramaturgical approaches are better understood as engagements with forms of truth-telling and witnessing. Examining a range of verbatim and testimonial plays from different parts of the world, the book develops new ways of understanding the performance of testimony and considers how dramaturgical theatre can bear witness to real events and individual and communal injustice through the re-enactment of personal testimony. Through its interrogation of different dramaturgical engagements with acts of witnessing, the book identifies certain forms of testimonial theatre move beyond psychoanalytical accounts of trauma and re-imagine testimony and witnessing as part of a decolonised project that looks beyond event based trauma, addressing instead of the experience of suffering wrought by racism and other forms of social injustice

EMOTION BELIEFS AND ATTITUDES: IMPLICATIONS FOR THE STOIC VIEW OF EMOTIONS AND A TEST OF SOME THEORIES OF PSYCHOTHERAPY

Traditional CBT and third-wave CBT, namely ACT, are widely used psychotherapy approaches. These psychotherapies have distinct philosophical and theoretical roots and, in turn, emphasize divergent approaches to emotions. The current study explored beliefs about emotions (emotion beliefs) associated with both approaches to psychotherapy, the relationship between emotion beliefs and emotion outcomes, as well as factors that mediate these relationships. Specifically, the study examined correlations between emotion beliefs (emotion controllability beliefs, acceptance of emotions, and emotion control values) and depression, anxiety, and anger. Correlation coefficients were compared to determine significant differences in associations between different emotion beliefs and emotion outcomes. It also examined whether emotion beliefs predicted depression, anxiety, and anger. Finally, this study investigated if emotion beliefs impacted depression, anxiety, and anger through different emotion regulation mechanisms (cognitive reappraisal and expressive suppression). Participants were undergraduate university students and adults in the general population, who completed a series of questionnaires through an online survey platform. Results demonstrated significant negative correlations between malleable emotion controllability beliefs and negative emotion outcomes and nonjudgmental attitudes about emotions and negative emotion outcomes. Emotion control values were not associated with negative emotion outcomes. Emotion controllability beliefs and nonjudgmental attitudes predicted all negative emotion outcomes examined in the present study, whereas emotion control values only predicted anxiety. The effect of emotion beliefs on depression and anxiety were partially mediated by cognitive reappraisal, but not expressive suppression. The effect of emotion beliefs on anger was not mediated by cognitive reappraisal. Limitations, future research, and implications for interventions are discussed

Sex ratio influences the motivational salience of facial attractiveness

The sex ratio of the local population influences mating-related behaviours in many species. Recent experiments show that male-biased sex ratios increase the amount of financial resources men will invest in potential mates, suggesting that sex ratios influence allocation of mating effort in humans. To investigate this issue further, we tested for effects of cues to the sex ratio of the local population on the motivational salience of attractiveness in own-sex and opposite-sex faces. We did this using an effort-based key-press task, in which the motivational salience of facial attractiveness was assessed in samples of faces in which the ratio of male to female images was manipulated. The motivational salience of attractive opposite-sex, but not own-sex, faces was greater in the own-sex-biased (high competition for mates) than in the opposite-sex-biased (low competition for mates) condition. Moreover, this effect was not modulated by participant sex. These results present new evidence that sex ratio influences human mating-related behaviours. They also present the first evidence that the perceived sex ratio of the local population may modulate allocation of mating effort in women, as well as men

Correlation between prescribing quality and pharmaceutical costs in English primary care: national cross-sectional analysis

Background Both pharmaceutical costs and quality-indicator performance vary substantially between general practices, but little is known about the relationship between prescribing costs and quality Aim To measure the association between prescribing quality and pharmaceutical costs among English general practices Design and setting Cross-sectional observational study using data from the Quality and Outcomes Framework and the Prescribing Analysis and Cost database from all 8409 general practices in England in 2005-2006 Method Correlation between practice achievement of 26 prescribing quality indicators in eight prescribing areas and related pharmaceutical costs was examined. Results There was no significant association between the overall achievement of quality indicators and related pharmaceutical costs (P= 0.399). Mean achievement of quality indicators across all eight prescribing areas was 79.0% (standard deviation 4.4%). There were small positive correlations in five prescribing areas: influenza vaccination, beta blockers, angiotensin converting enzyme inhibitors, lipid lowering, and antiplatelet treatment (all

Introduction (To Acting Out Trauma Special Issue)

Evoking Freud’s essay ‘Remembering, Repeating and Working Through’, first published in 1914, the title of this special issue of Performing Ethos invites us to think about the ethics of enactment and performance in relation to remembrance and the event of trauma

DNA Demethylation in Pluripotency and Reprogramming: The Role of Tet Proteins and Cell Division

Cytosine methylation is found in the genomes of many plants and animals and has been associated with transcriptional silencing in mammals. At critical stages in embryo development, when cellular potential is reset, DNA methylation is lost in a series of “sequential waves.” The mechanism underlying this is controversial and complex. Several new reports now suggest that TET enzymes and cell division are important for these in vivo transitions as well as for experimentally induced reprogramming

The reward value of infant facial cuteness tracks within-subject changes in women’s salivary testosterone

“Baby schema” refers to infant characteristics, such as facial cues, that positively influence cuteness perceptions and trigger caregiving and protective behaviors in adults. Current models of hormonal regulation of parenting behaviors address how hormones may modulate protective behaviors and nurturance, but not how hormones may modulate responses to infant cuteness. To explore this issue, we investigated possible relationships between the reward value of infant facial cuteness and within-woman changes in testosterone, estradiol, and progesterone levels. Multilevel modeling of these data showed that infant cuteness was more rewarding when women’s salivary testosterone levels were high. Moreover, this within-woman effect of testosterone was independent of the possible effects of estradiol and progesterone and was not simply a consequence of changes in women’s cuteness perceptions. These results suggest that testosterone may modulate differential responses to infant facial cuteness, potentially revealing a new route through which testosterone shapes selective allocation of parental resources

Women's hormone levels modulate the motivational salience of facial attractiveness and sexual dimorphism

The physical attractiveness of faces is positively correlated with both behavioral and neural measures of their motivational salience. Although previous work suggests that hormone levels modulate women's perceptions of others’ facial attractiveness, studies have not yet investigated whether hormone levels also modulate the motivational salience of facial characteristics. To address this issue, we investigated the relationships between within-subject changes in women's salivary hormone levels (estradiol, progesterone, testosterone, and estradiol-to-progesterone ratio) and within-subject changes in the motivational salience of attractiveness and sexual dimorphism in male and female faces. The motivational salience of physically attractive faces in general and feminine female faces, but not masculine male faces, was greater in test sessions where women had high testosterone levels. Additionally, the reward value of sexually dimorphic faces in general and attractive female faces, but not attractive male faces, was greater in test sessions where women had high estradiol-to-progesterone ratios. These results provide the first evidence that the motivational salience of facial attractiveness and sexual dimorphism is modulated by within-woman changes in hormone levels
