Cross-national aspects of cyberbullying victimization among 14-17-year-old adolescents across seven European countries.

BACKGROUND: The increasing use of the Internet and social network sites (SNS) has created a new domain of socio-emotional development for adolescents. The aim of this cross-sectional study was to explore cybervictimization across seven European countries, in relation to socio-demographic, Internet use and psychosocial variables. METHODS: A cross-sectional school-based study was conducted in the participating countries: Germany, Greece, Iceland the Netherlands, Poland, Romania and Spain. Anonymous self-completed questionnaires included sociodemographic data, internet usage characteristics, school achievement, parental control, the Internet Addiction Test and Achenbach's Youth Self-Report. RESULTS: The highest rate of cyber victimization was found in Romania (37.3%) and the lowest in Spain (13.3%). Multiple logistic regression analyses gave differing results between countries. In Romania, Poland and Germany cyberbullying victimization was associated with SNS use, whereas Internet use was associated with increased odds of cybervictimization only in Romania. Cybervictimization was associated with greater internalizing behavior problems in all countries analysed, and with externalizing problems in all except Romania. CONCLUSIONS: Cyberbullying victimization is an on-going problem, which is subject to country-specific socio-demographic factors and diverse patterns of current Internet use and its development. Preventive measures should emphasize the integration of Internet communication technology education in educational contexts, and focus on the consistent association between cybervictimization and internalizing and externalizing difficulties.

A systematic review and meta-analysis of the traumatogenic phenotype hypothesis of psychosis.

BACKGROUND: Developmental trauma increases psychosis risk and is associated with poor prognosis. It has been proposed that psychosis in survivors of developmental trauma gives rise to a distinct 'traumatogenic' phenotype. AIMS: Given the implications for personalised treatment, we sought to explore the traumatogenic psychosis phenotype hypothesis in a systematic review and meta-analysis of studies comparing psychotic presentations between adults with and without developmental trauma histories. METHOD: We registered the systematic review on PROSPERO (CRD42019131245) and systematically searched EMBASE, Medline and PsycINFO. The outcomes of interests were quantitative and qualitative comparisons in psychotic symptom expression (positive, negative, cognitive) and other domains of psychopathology, including affect regulation, sleep, depression and anxiety, between adults with and without experience of developmental trauma. RESULTS: Of 34 studies included (N = 13 150), 11 were meta-analysed (n = 2842). A significant relationship was found between developmental trauma and increased symptom severity for positive (Hedge's g = 0.27; 95% CI 0.10-0.44; P = 0.002), but not negative symptoms (Hedge's g = 0.13; 95% CI -0.04 to 0.30; P = 0.14). Developmental trauma was associated with greater neurocognitive, specifically executive, deficits, as well as poorer affect, dissociation and social cognition. Furthermore, psychotic symptom content thematically related to traumatic memories in survivors of developmental trauma. CONCLUSIONS: Our findings that developmental trauma is associated with more severe positive and affective symptoms, and qualitative differences in symptom expression, support the notion that there may be a traumatogenic psychosis phenotype. However, underdiagnosis of post-traumatic stress disorder may also explain some of these findings. More research is needed to explore this further.

The effectiveness of trauma-focused psychotherapy for complex post-traumatic stress disorder: A retrospective study.

OBJECTIVE: We retrospectively evaluated the effectiveness of trauma-focused psychotherapy (TF-P) versus stabilization and waiting in a civilian cohort of patients with an 11th version of the international classification of disease (ICD-11) diagnosis of complex post-traumatic stress disorder (CPTSD). METHODS: We identified patients with CPTSD treated at a specialist trauma service over a 3-year period by triangulating evidence from self-report questionnaires, file review, and expert-clinician opinion. Patients completed a phase-based treatment: stabilization consisting of symptom management and establishing safety, followed by waiting for treatment (phase 1); individual TF-P in the form of trauma-focused cognitive behavioral therapy (TF-CBT), or eye movement desensitization and reprocessing (EMDR) or TF-CBT plus EMDR (phase 2). Our primary outcome was PTSD symptoms during phase 2 versus phase 1. Secondary outcomes included depressive symptoms, functional impairment, and a proxy CPTSD measure. Exploratory analysis compared outcomes between treatments. Adverse outcomes were recorded. RESULTS: Fifty-nine patients were included. Compared to receiving only phase 1, patients completing TF-P showed statistically significant reductions in PTSD [t(58) = -3.99, p < 0.001], depressive symptoms [t(58) = -4.41, p < 0.001], functional impairment [t(58) = -2.26, p = 0.028], and proxy scores for CPTSD [t(58) = 4.69, p < 0.001]. There were no significant differences in outcomes between different treatments offered during phase 2. Baseline depressive symptoms were associated with higher PTSD symptoms and functional impairment. CONCLUSIONS: This study suggests that TF-P effectively improves symptoms of CPTSD. However, prospective research with validated measurements is necessary to evaluate current and new treatments and identify personal markers of treatment effectiveness for CPTSD.
