Title Dust and metallicity in carbon stars Type Conference Article
Year 2015 Publication Abbreviated Journal
Volume Issue Pages 216.04-216.04
Keywords
Abstract The Infrared Spectrograph on the Spitzer Space Telescope observed over 200 carbon stars in nearby metal-poor dwarf galaxies. These spectra probe how the quantity and composition of dust produced by carbon stars depend on initial metallicity, initial mass, and pulsational properties. For stars to produce significant quantities of dust, they must be pulsating in the fundamental mode with strong amplitudes. The spectra confirm that carbon stars with longer pulsation periods produce more dust and that the amount of dust shows no strong dependence on metallicity. This sample includes more carbon stars with low mass and reveals that for a given pulsation period, higher-mass stars produce less dust. Evidence is building for the layering of dust grains, with SiC cores in grains produced by metal-rich carbon stars, and mantles of MgS around grains in all embedded stars.

Title The Dissociative Subtype of PTSD Scale: Initial Evaluation in a National Sample of Trauma-Exposed Veterans Type Journal Article
Year 2015 Publication Assessment Abbreviated Journal Assessment
Volume Issue Pages
Keywords Ptsd; dissociative subtype; latent profile analysis; psychometric
Abstract The fifth edition of the Diagnostic and Statistical Manual includes a dissociative subtype of posttraumatic stress disorder, but no existing measures specifically assess it. This article describes the initial evaluation of a 15-item self-report measure of the subtype called the Dissociative Subtype of Posttraumatic Stress Disorder Scale (DSPS) in an online survey of 697 trauma-exposed military veterans representative of the U.S. veteran population. Exploratory factor analyses of the lifetime DSPS items supported the intended structure of the measure consisting of three factors reflecting derealization/depersonalization, loss of awareness, and psychogenic amnesia. Consistent with prior research, latent profile analyses assigned 8.3% of the sample to a highly dissociative class distinguished by pronounced symptoms of derealization and depersonalization. Overall, results provide initial psychometric support for the lifetime DSPS scales; additional research in clinical and community samples is needed to further validate the measure.

Title The Symptoms of Trauma Scale (SOTS): An Initial Psychometric Study Type Journal Article
Year 2015 Publication Journal of Psychiatric Practice Abbreviated Journal J Psychiatr Pract
Volume 21 Issue 6 Pages 474-483
Keywords
Abstract The Symptoms of Trauma Scale (SOTS) is a 12-item, interview-based, clinician-rated measure that assesses the severity of a range of trauma-related symptoms. This pilot study evaluated its use and psychometric properties in an outpatient setting that provides treatment to survivors of chronic interpersonal trauma. Thirty participants completed self-report measures of posttraumatic stress symptoms, depression, dissociation, self-esteem, and affect dysregulation; the participants also participated separately in a semistructured interview based on the SOTS conducted by 2 trained interviewers. SOTS composite severity scores for DSM-IV posttraumatic stress disorder (PTSD) and complex PTSD (cPTSD), DSM-5 PTSD, and PTSD dissociative subtype, and total traumatic stress symptoms generally had acceptable internal consistency and interrater reliability. Evidence of convergent, discriminant, criterion, and construct validity was found for the SOTS composite PTSD scores, although potential limitations to validity that require further research and refinement of the measure were identified for the SOTS total and DSM-IV cPTSD scores and the hyperarousal, affect dysregulation, and dissociation items. Interviewers and interviewees described the interview as efficient, informative, and well tolerated. Implications for clinical practice and research to refine the SOTS are discussed.

Title Less is more? Assessing the validity of the ICD-11 model of PTSD across multiple trauma samples Type Journal Article
Year 2015 Publication European Journal of Psychotraumatology Abbreviated Journal Eur J Psychotraumatol
Volume 6 Issue Pages 28766
Keywords Cfa; Dsm-5; Icd-11; Ptsd; latent structure
Abstract BACKGROUND: In the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the symptom profile of posttraumatic stress disorder (PTSD) was expanded to include 20 symptoms. An alternative model of PTSD is outlined in the proposed 11th edition of the International Classification of Diseases (ICD-11) that includes just six symptoms. OBJECTIVES AND METHOD: The objectives of the current study are: 1) to independently investigate the fit of the ICD-11 model of PTSD, and three DSM-5-based models of PTSD, across seven different trauma samples (N=3,746) using confirmatory factor analysis; 2) to assess the concurrent validity of the ICD-11 model of PTSD; and 3) to determine if there are significant differences in diagnostic rates between the ICD-11 guidelines and the DSM-5 criteria. RESULTS: The ICD-11 model of PTSD was found to provide excellent model fit in six of the seven trauma samples, and tests of factorial invariance showed that the model performs equally well for males and females. DSM-5 models provided poor fit of the data. Concurrent validity was established as the ICD-11 PTSD factors were all moderately to strongly correlated with scores of depression, anxiety, dissociation, and aggression. Levels of association were similar for ICD-11 and DSM-5 suggesting that explanatory power is not affected due to the limited number of items included in the ICD-11 model. Diagnostic rates were significantly lower according to ICD-11 guidelines compared to the DSM-5 criteria. CONCLUSIONS: The proposed factor structure of the ICD-11 model of PTSD appears valid across multiple trauma types, possesses good concurrent validity, and is more stringent in terms of diagnosis compared to the DSM-5 criteria.

Title Posttraumatic Stress Disorder and Psychopathology in Dancers Type Journal Article
Year 2015 Publication Medical Problems of Performing Artists Abbreviated Journal Med Probl Perform Art
Volume 30 Issue 3 Pages 157-162
Keywords Adult; Cross-Sectional Studies; Dancing/*psychology; Depression/epidemiology/psychology; Female; Humans; Male; Mental Health/*statistics & numerical data; Middle Aged; Multivariate Analysis; Occupational Diseases/epidemiology/*psychology; Stress Disorders, Post-Traumatic/epidemiology/*psychology; Stress, Psychological/epidemiology/psychology; Young Adult
Abstract This study investigated the prevalence of posttraumatic stress disorder (PTSD) in pre-professional and professional dancers (n=209) who were exposed to traumatic events. Nine self-report instruments assessed (1) adverse childhood experiences, (2) past traumatic events, (3) coping strategies under stressful situations, and (4) fantasy proneness. The psychopathology variables included (5) anxiety, (6) depression, (7) dissociation, (8) shame, and (9)) PTSD diagnostic scale. Statistical calculations included descriptive, distributional, and multivariate analysis of covariates (MANCOVA). Results indicate that dancers had a significantly higher distribution of PTSD (20.2%) compared to the normal population (7.8%). They also had a higher frequency of family members with mental illness, an inability to speak about their trauma, and more suicidal thoughts. The PTSD group of dancers had higher levels of psychopathology (anxiety, depression, dissociation, and shame) and they had more childhood adversity and adult trauma. Compared to the no-PTSD group, the PTSD group had higher scores on fantasy proneness and emotion-oriented coping strategies. These coping strategies may increase psychological instability. Addressing early abuse and trauma is recommended. Clinicians may help dancers alter their internal working models that their self is worthless, others are abusive, and the world is threatening and dangerous. By understanding PTSD in dancers, medical and mental health treatment protocols may be established to address the debilitating, and often hidden, symptoms of PTSD.

Title Trauma-Related Altered States of Consciousness (TRASC) and Functional Impairment I: Prospective Study in Acutely Traumatized Persons 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 5 Pages 500-519
Keywords 4-D model; childhood abuse and neglect; dissociation; posttraumatic stress disorder; trauma-related altered states of consciousness
Abstract A theoretical framework referred to as a 4-D model has been described for classifying posttraumatic stress symptoms into those potentially occurring within normal waking consciousness (NWC) versus those thought to intrinsically exemplify dissociative experiences, specifically, trauma-related altered states of consciousness (TRASC). As a further test of this theoretical distinction, this prospective study evaluated whether TRASC and NWC forms of distress incrementally and prospectively predicted functional impairment at 6 and 12 weeks following presentation at hospital emergency departments in the acute aftermath of traumatic events in 180 persons. Establishing the clinical significance of both TRASC and NWC-distress symptoms, we found that 6-week markers of TRASC and NWC-distress independently predicted 12-week self-reported levels of social and occupational impairment. We also observed broad support for various predictions of the 4-D model except that, in contrast with hypotheses, childhood trauma history was generally more strongly correlated with symptoms of NWC-distress than with TRASC. Future research directions are discussed.

Title Trauma-Related Altered States of Consciousness (TRASC) and Functional Impairment II: Perceived Causal Relationships in an Online Sample 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 5 Pages 520-540
Keywords 4-D model; childhood abuse and neglect; dissociation; posttraumatic stress disorder; trauma-related altered states of consciousness
Abstract Research supports the existence of a dissociative subtype of posttraumatic stress disorder, although studies have not directly compared the perceived impact of dissociative versus nondissociative posttraumatic symptoms on social and occupational functioning. In addition, research is beginning to differentiate between posttraumatic distress associated with normal waking consciousness (NWC) and dissociative experiences of trauma-related altered states of consciousness (TRASC) along multiple phenomenological dimensions. The current study investigated perceived causal relationships between posttraumatic symptoms associated with NWC-distress and TRASC on the one hand and interpersonal and occupational functioning on the other. Although both TRASC and NWC-distress independently accounted for variance in self-reported interpersonal and occupational problems, perceived causal relationship results showed that individuals tended to attribute their social and work-related problems more strongly to NWC-distress than to TRASC. Future research directions are discussed.

Title Dissociative, depressive, and PTSD symptom severity as correlates of nonsuicidal self-injury and suicidality in dissociative disorder patients 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 Issue Pages 1-14
Keywords Childhood abuse; dissociation; dissociative disorders; dissociative identity disorder; posttraumatic stress disorder; suicide
Abstract The present study investigates whether symptom severity can distinguish patients diagnosed with dissociative identity disorder and dissociative disorder not otherwise specified with a recent history of nonsuicidal self-injury (NSSI) and suicide attempts from those patients without recent self-harm. A total of 241 clinicians reported on recent history of patient NSSI and suicide attempts. Of these clinicians' patients, 221 completed dissociative, depressive, and posttraumatic stress disorder symptomatology measures. Baseline cross-sectional data from a naturalistic and prospective study of dissociative disorder patients receiving community treatment were utilized. Analyses evaluated dissociative, depressive, and posttraumatic stress disorder symptom severity as methods of classifying patients into NSSI and suicide attempt groupings. Results indicated that dissociation severity accurately classified patients into NSSI and suicidality groups, whereas depression severity accurately classified patients into NSSI groups. These findings point to dissociation and depression severity as important correlates of NSSI and suicidality in patients with dissociative disorders and have implications for self-harm prevention and treatment.

Title Paradoxical Pain Perception in Posttraumatic Stress Disorder: The Unique Role of Anxiety and Dissociation Type Journal Article
Year 2015 Publication The Journal of Pain : Official Journal of the American Pain Society Abbreviated Journal J Pain
Volume 16 Issue 10 Pages 961-970
Keywords Chronic pain; anxiety; dissociation; hyperresponsiveness; hypoalgesia; posttraumatic stress disorder; psychophysics
Abstract Posttraumatic stress disorder (PTSD) and chronic pain often co-occur and exacerbate each other. Elucidating the mechanism of this co-occurrence therefore has clinical importance. Previously, patients with PTSD with chronic pain were found to demonstrate a unique paradoxical pain profile: hyperresponsiveness together with hyposensitivity to pain. Our aim was to examine whether 2 seemingly paradoxical facets of PTSD (anxiety and dissociation) underlie this paradoxical profile. Patients with PTSD (n = 32) and healthy control individuals (n = 43) underwent psychophysical testing and completed questionnaires. Patients with PTSD had higher pain thresholds and higher pain ratings to suprathreshold stimuli than control individuals. Pain thresholds were positively associated with dissociation levels and negatively associated with anxiety sensitivity levels. Experimental pain ratings were positively associated with anxiety sensitivity and negatively related to dissociation levels. Chronic pain intensity was associated with anxiety, anxiety sensitivity, and pain catastrophizing. It appears that reduced conscious attention toward incoming stimuli, resulting from dissociation, causes delayed response in pain threshold measurement, whereas biases toward threatening stimuli and decreased inhibition, possibly caused by increased anxiety, are responsible for the intensification of experimental and chronic pain. The paradoxical facets of PTSD and their particular influences over pain perception seem to reinforce the coexistence of PTSD and chronic pain, and should be considered when treating traumatized individuals. PERSPECTIVE: This article provides new information regarding the underlying mechanism of the coexistence of PTSD and chronic pain. This knowledge could help to provide better management of PTSD and chronic pain among individuals in the aftermath of trauma.
