MEDIATING ROLE OF DISSOCIATION SYMPTOMS BETWEEN ADOLESCENT COMPULSIVE INTERNET USE ACROSS TIME

2020

The aim of this study was to examine adolescent compulsive internet use (CIU) across a one-year period, to examine associations with symptoms of depression, anxiety and dissociation, as well as to analyze the potential mediating effect of dissociation symptoms.  Previous studies have indicated that dissociation might serve as a coping strategy and/or as a consequence of problematic internet use. Participating in the study were 80 adolescents (39 girls and 41 boys), ages from 12 to 18 (mean age 14.90 years) at the time of the first measurement.  At Time 1 and one year later at Time 2 measurement points the participants completed the Trauma Symptom Checklist (Briere, 1995) and items from the …

IntroductionSuccess rates of psychotherapy in post-traumatic stress disorder related to childhood maltreatment (PTSD-CM) are limited.Methods and analysisObserver-blind multicentre randomised clinical trial (A-1) of 4-year duration comparing enhanced methods of STAIR Narrative Therapy (SNT) and of trauma-focused psychodynamic therapy (TF-PDT) each of up to 24 sessions with each other and a minimal attention waiting list in PTSD-CM. Primary outcome is severity of PTSD (Clinician-Administered PTSD Scale for DSM-5 total) assessed by masked raters. For SNT and TF-PDT, both superiority and non-inferiority will be tested. Intention-to-treat analysis (primary) and per-protocol analysis (secondary).…

Psychopathology, Dissociation and Somatic Symptoms in Adolescents Who Were Exposed to Traumatic Experiences

2018

Background: The direct and long-term effects of children’s exposure to traumatic events can be seen in a complex continuum, based first of all on the type of trauma. Children’s reactions to trauma may have different manifestations from the clinical picture of the PTSD, exhibiting dissociative, somatic, depressive or anxiety symptoms, and/or disruptiveness. Aim: we conducted a cross-sectional study in a psychiatric patients sample to determine the extent to which complex trauma history is associated with disease-related characteristics (diagnosis, dissociative symptoms, somatic symptomatology, impairment degree). Methods: We have enrolled 107 subjects, aged between 12 and 18 years, who conse…

Psilocybin as an Inducer of Ego Death and Similar Experiences of Religious Provenance

2016

Abstract The purpose of this chapter is to provide an overview of the impact of hallucinogenic psilocybin on religious-type emotionality related to ego disintegration. Psilocybin as a typical hallucinogen evokes alternations of visual perception (enhances a development of pseudo-hallucinations, phantom visual perception, or hypnagogic experiences). These visual phenomena may be inspiring and are claimed to enhance aesthetic appreciation. Additionally the hallucinogen induces transient impairment of cognitive functions and psychological regression comparable to the signs of ego blurring and dissociative phenomena. The psilocybin effects, initially euphoric, may become emotionally perceived a…

The Relationship Between Dissociative Experiences and Cannabis Use: a Systematic Review

2019

Purpose of Review This systematic review aimed to investigate the relation between cannabis use and dissociation. Recent Findings Four analytical and 14 descriptive cross-sectional studies were included. There is no variation in the rates of cannabis use among individuals with dissociative experiences compared with the general population. In addition, the prevalence of dissociative disorders in subjects using cannabis is not different from those not using cannabis. The majority of the studies employed inadequate sampling procedures and a concurrent or retrospective assessment of the two variables, which might have increased the risk of bias, and only a few of them controlled for potential c…

Exploring the Effectiveness of Dialectical Behavior Therapy Versus Systems Training for Emotional Predictability and Problem Solving in a Sample of P…

2021

Dialectical behavior therapy (DBT) and systems training for emotional predictability and problem solving (STEPPS) are two treatment protocols for people with borderline personality disorder (BPD) that have received important empirical support. However, their possible differential effectiveness has not yet been studied. The objective of this study is to explore the effectiveness of these two treatment programs. A nonrandomized clinical trial was carried out in which both treatments were applied for six months. The sample consisted of 72 patients diagnosed with BPD. The results indicate that both groups experienced a statistically significant reduction in BPD symptom, emotional regulation, i…

Sudden Complex Hallucinations in a 14-Year-Old Girl: Schizophrenia Spectrum Disorders Versus Dissociative Disorders-The Influence of Early Life Exper…

2020

A 14-year-old girl is taken to the pediatric emergency department (ED) by her parents because of sudden complex hallucinations.She shows moderate intellectual disability without a peculiar phenotype already evaluated by neuropediatrics (normal comparative genomic hybridization array and brain magnetic resonance imaging) and most likely related to affective deprivation at the orphanage. Adopted at 20 months from China, her parents reported that on arrival she had scars, allegedly from being tied to a chair for a long time, and that although she was able to stand, she could not walk. At 22 months, she had experienced several episodes of loss of consciousness with rigidity that were attributed…

Post-traumatic Stress Disorder Associated to Long-term Dissociative Fugue: A Case Report

2009

Aims:Since the end of 19th century, mental health professionals have noticed that individuals who have experienced traumatic situations often present dissociative symptoms, such as amnesia or fugue states. Dissociation is a defensive mechanism that allows an individual to separate from conscience the psychological distress produced by the trauma. Our aim was to remark the association between Post-traumatic Stress Disorder (PTSD) and long-term dissociative disorders through the study of a clinical case.Method:A clinical case was followed and reviewed to illustrate this relationship.Results:Ten years ago, a 49-year-old man was diagnosed of PTSD after having witnessed several colleagues burnt …

Radiofrequency and 2.45 GHz electron cyclotron resonance H− volume production ion sources

2016

The volume production of negative hydrogen ions (H-) in plasma ion sources is based on dissociative electron attachment (DEA)to rovibrationally excited hydrogen molecules(H2), which is a two-step process requiring both, hot electrons for ionization, and vibrational excitation of the H2 and cold electrons for the H- formation through DEA. Traditionally H- ion sources relying on the volume production have been tandem-type arc discharge sources equipped with biased filament cathodes sustaining the plasma by thermionic electron emission and with a magnetic filter separating the main discharge from the H- formation volume. The main motivation to develop ion sources based on radiofrequency (RF) o…

The Role of Excited Oxygen Molecules in the Formation of the Secondary Ozone Layer at 87 to 97 km

2018

The secondary ozone layer is located at elevations of 87 to 97 km in the upper mesosphere – lower thermosphere. It overlaps with the ionospheric D-layer. Daytime intensive UV radiation is dissociating O2 molecules to O atoms and photoexcitating O2 molecules up to 11.07eV level. Ozone photolysis between the wavelengths of 118.7–121.6 nm produces three oxygen atoms from one ozone molecule. Collision reactions of O2(B3 Σu —) and O2(X3 Σg —, υ≥26) with O2(X3 Σg —, υ=0) produce additional oxygen atoms. The number of oxygen atoms is maintained at such a high level that a small but significant ozone concentration survives. UV radiation weakens radically during the night. The number of O atoms show…
