Posttraumatic stress disorder symptoms among trauma-exposed adolescents from low- and middle-income countries.

Background: Exposure to traumatic events in childhood is associated with the development and maintenance of various psychiatric disorders, but most frequently with posttraumatic stress disorder (PTSD). The aim of this study was to evaluate the types of traumatic events experienced and the presence and predictors of PTSD symptoms among adolescents from the general population from ten low- and middle-income countries (LMICs).

Methods: Data were simultaneously collected from 3370 trauma-exposed adolescents (mean age = 15.

External locus-of-control partially mediates the association between cumulative trauma exposure and posttraumatic stress symptoms among adolescents from diverse background.

Locus of control (LOC) is a modifiable mediator of symptoms of posttraumatic stress disorder (PTSD) among traumatized individuals and a potential target of intervention. Compared with studies involving adults, the potential mediation effect of LOC on PTSD symptoms among trauma-exposed children and adolescents is relatively under-explored. This study, therefore, assessed the mediation effects of LOC on the association between lifetime cumulative trauma and PTSD symptoms among a large cohort of adolescents from different cultural background.

UCLA PTSD reaction index for DSM-5 (PTSD-RI-5): a psychometric study of adolescents sampled from communities in eleven countries.

: Children and adolescents are often exposed to traumatic events, which may lead to the development of posttraumatic stress disorder (PTSD). It is therefore important for clinicians to screen for potential symptoms that can be signs of PTSD onset. PTSD in youth is a worldwide problem, thus congruent screening tools in various languages are needed.

Cross-Cultural Measurement Invariance of Adolescent Self-Report on the Pediatric Quality of Life Inventory 4.0.

This study evaluated the cross-cultural measurement invariance of the Pediatric Quality of Life Inventory version 4.0 (PedsQL) among adolescents sampled from Bulgaria, Croatia, India, Indonesia, Nigeria, Serbia, and Turkey. The multiple-indicator multiple-cause (MIMIC) model was used, which allowed controlling of demographic variables (i.
