Title DSM-5's posttraumatic stress disorder with dissociative symptoms: challenges and future directions Type Journal Article
Year 2015 Publication Journal of Trauma & Dissociation : the Official Journal of the International Society for the Study of Dissociation (ISSD) Abbreviated Journal J Trauma Dissociation
Volume 16 Issue 1 Pages 7-28

Abstract The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, formally recognizes a dissociative subtype of posttraumatic stress disorder (PTSD; PTSD with dissociative symptoms). This nomenclative move will boost empirical and theoretical efforts to further understand the links between dissociation, trauma, and PTSD. This article examines the empirical literature showing that patients with PTSD can be divided into 2 different groups based on their neurobiology, psychological symptom profile, history of exposure to early relational trauma, and depersonalization/derealization symptoms. It then explores the conceptual and empirical challenges of conceiving 1 of these types as reflecting a “dissociative” type of PTSD. First, this classification is based on the presence of a limited subset of dissociative symptoms (i.e., depersonalization, derealization). This sets aside an array of positive and negative psychoform and somatoform dissociative symptoms that may be related to PTSD. Second, empirical evidence suggests heightened dissociation in PTSD compared to many other disorders, indicating that dissociation is relevant to PTSD more broadly rather than simply to the so-called dissociative subtype. This article sets out important issues to be examined in the future study of dissociation in PTSD, which needs to be informed by solid conceptual understandings of dissociation.

Title Sources of diel variation in energetic physiology in an Arctic-breeding, diving seaduck Type Journal Article
Year 2015 Publication Abbreviated Journal General and Comparative Endocrinology
Volume 216 Issue Pages 39-45
Keywords Arctic; Corticosterone; Diel rhythm; Energetic physiology; Sea duck; Triglyceride
Abstract Diel variation in baseline glucocorticoid (GC) secretion influences energetics and foraging behaviors. In temperate breeding, diurnal vertebrates, studies have shown that daily patterns of baseline GC secretion are influenced by environmental photoperiod, with baseline GCs peaking prior to sunrise to stimulate waking and foraging behaviors. Measures of physiological energy acquisition are also expected to peak in response to foraging activity, but their relationship to GC levels have not been well studied. In contrast to temperate breeding species, virtually nothing is known about diel GC and energetic metabolite secretion in Arctic breeding species, which experience almost constant photoperiods in spring and summer. Using a ten-year dataset, we examined the daily, 24-h pattern of baseline corticosterone (CORT) and triglyceride (TRIG) secretion in approximately 800 female pre-breeding Arctic-nesting common eiders (. Somateria mollissima). We related these traits to environmental photoperiod and to tidal cycle. In contrast to temperate breeding species, we found that that neither time of day nor tidal trend predicted diel variation in CORT or TRIG secretion in Arctic-breeding eiders. Given the narrow window of opportunity for breeding in polar regions, we suggest that eiders must decouple their daily foraging activity from light and tidal cycles if they are to accrue sufficient energy for successful breeding. As CORT is known to influence foraging behavior, the absence of a distinct diel pattern of CORT secretion may therefore be an adaptation to optimize reproductive investment and likelihood for success in some polar-breeding species. © 2015 Elsevier Inc.

Title Pre-breeding energetic management in a mixed-strategy breeder Type Journal Article
Year 2015 Publication Abbreviated Journal Oecologia
Volume 177 Issue 1 Pages 235-243
Keywords Breeding threshold; Corticosterone; Energetic management; Energetic metabolites; Mixed-strategy breeder
Abstract Integrative biologists have long appreciated that the effective acquisition and management of energy prior to breeding should strongly influence fitness-related reproductive decisions (timing of breeding and reproductive investment). However, because of the difficulty in capturing pre-breeding individuals, and the tendency towards abandonment of reproduction after capture, we know little about the underlying mechanisms of these life-history decisions. Over 10 years, we captured free-living, arctic-breeding common eiders (Somateria mollissima) up to 3 weeks before investment in reproduction. We examined and characterized physiological parameters predicted to influence energetic management by sampling baseline plasma glucocorticoids (i.e., corticosterone), very-low-density lipoprotein (VLDL), and vitellogenin (VTG) for their respective roles in mediating energetic balance, rate of condition gain (physiological fattening rate) and reproductive investment. Baseline corticosterone increased significantly from arrival to the initiation of reproductive investment (period of rapid follicular growth; RFG), and showed a positive relationship with body mass, indicating that this hormone may stimulate foraging behaviour to facilitate both fat deposition and investment in egg production. In support of this, we found that VLDL increased throughout the pre-breeding period, peaking as predicted during RFG. Female eiders exhibited unprecedentedly high levels of VTG well before their theoretical RFG period, a potential strategy for pre-emptively depositing available protein stores into follicles while females are simultaneously fattening. This study provides some of the first data examining the temporal dynamics and interaction of the energetic mechanisms thought to be at the heart of individual variation in reproductive decisions and success in many vertebrate species. © 2014, Springer-Verlag Berlin Heidelberg.

Title Top-down vs. bottom-up drivers of recruitment in a key marine invertebrate: Investigating early life stages of snow crab Type Journal Article
Year 2015 Publication Abbreviated Journal ICES Journal of Marine Science
Volume 72 Issue 5 Pages 1336-1348
Keywords cannibalism; climate; groundfish predation; larval production; population dynamics; recruitment; snow crab
Abstract Many snow crab fisheries have fluctuated widely over time in a quasi-cyclic way due to highly variable recruitment. The causes of this variability are still debated. Bottom-up processes related to climate variability may strongly affect growth and survival during early life, whereas top-down predator effects may be a major source of juvenile mortality. Moreover, intrinsic density-dependent processes, which have received much less attention, are hypothetically responsible for the cycles in recruitment. This study explored how climate, larval production, intercohort cannibalism and groundfish predation may have affected recruitment of early juvenile snow crab in the northwest Gulf of St Lawrence (eastern Canada) over a period of 23 years. Abundance of early juvenile snow crabs (2.5-22.9 mm in carapace width), representing the first 3 years of benthic life, came from an annual trawl survey and was used to determine cohort strength. Analyses revealed a cyclic pattern in abundance of 0+ crabs that may arise from cohort resonant effects. This pattern consisted of three recruitment pulses but was reduced to two pulses by age 2+, while the interannual variability of cohort strength was dampened. This reconfiguration of the earliest recruitment pattern was dictated primarily by bottom water temperature and cannibalism, which progressively overruled the pre-settlement factors of larval production and surface water temperature that best explained abundance of 0+ crabs. The results strongly suggest that bottom-up and density-dependent processes prevail over top-down control in setting the long-term trends and higher-frequency oscillations of snow crab early recruitment patterns. © 2015 International Council for the Exploration of the Sea 2015.

Title An Open Trial Of Emotion Regulation Therapy For Generalized Anxiety Disorder And Cooccurring Depression Type Journal Article
Year 2015 Publication Depression and Anxiety Abbreviated Journal Depress Anxiety
Volume 32 Issue 8 Pages 614-623
Keywords Adult; Anxiety Disorders/epidemiology/*therapy; Cognitive Therapy/*methods; Comorbidity; Depressive Disorder, Major/epidemiology/*therapy; Emotions/*physiology; Female; Humans; Male; Middle Aged; Stress Disorders, Traumatic, Acute; Treatment Outcome; anxiety/anxiety disorders; behavior therapy; clinical trials; depression; emotion regulation; generalized anxiety disorder; mindfulness/meditation; treatment
Abstract BACKGROUND: Although CBT is efficacious for a wide variety of psychiatric conditions, relatively fewer GAD patients achieve high endstate functioning as compared to patients receiving CBTs for other disorders. Moreover, GAD trials that utilized patient samples without prominent depression have tended to report that effect sizes for depressive outcomes were small or diminished to pretreatment levels in the follow-up period. Emotion regulation therapy (ERT) integrates principles from traditional and contemporary cognitive behavioral treatments with basic and translational findings from affect science to offer a blueprint for improving intervention by focusing on motivational, regulatory, and contextual learning mechanisms. METHOD: The purpose of this investigation was to provide initial support for the efficacy of ERT in an open trial of patients with GAD and cooccurring depressive symptoms. Twenty-one patients received a 20-session version of ERT delivered in weekly individual sessions. Standardized clinician ratings and self-report measures were assessed at pre-, mid-, and posttreatment as well as at three- and nine-month follow-ups. Intent-to-treat analyzes were utilized. RESULTS: GAD patients, half with comorbid major depression, evidenced statistically, and clinically meaningful improvements in symptom severity, impairment, quality of life, and in model-related outcomes including emotional/motivational intensity, mindful attending/acceptance, decentering, and cognitive reappraisal. Patients maintained gains across the three and nine month follow-up periods. CONCLUSIONS: These findings, although preliminary, provide additional evidence for the role of emotion dysregulation in the onset, maintenance, and now treatment of conditions such as GAD and cooccurring depressive symptoms.

Title The role of emotion and emotion regulation in social anxiety disorder Type Journal Article
Year 2015 Publication Current Psychiatry Reports Abbreviated Journal Curr Psychiatry Rep
Volume 17 Issue 1 Pages 531
Keywords Anxiety Disorders/*psychology/*therapy; Cognitive Therapy/methods; *Emotions; Humans; Internal-External Control; Mindfulness/methods; *Social Behavior
Abstract Many psychiatric disorders involve problematic patterns of emotional reactivity and regulation. In this review, we consider recent findings regarding emotion and emotion regulation in the context of social anxiety disorder (SAD). We first describe key features of SAD which suggest altered emotional and self-related processing difficulties. Next, we lay the conceptual foundation for a discussion of emotion and emotion regulation and present a common framework for understanding emotion regulation, the process model of emotion regulation. Using the process model, we evaluate the recent empirical literature spanning self-report, observational, behavioral, and physiological methods across five specific families of emotion regulation processes-situation selection, situation modification, attentional deployment, cognitive change, and response modulation. Next, we examine the empirical evidence behind two psychosocial interventions for SAD: cognitive behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR). Throughout, we present suggestions for future directions in the continued examination of emotion and emotion regulation in SAD.
