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

Background: 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. Objective: The aim of this study was to test the general psychometric properties of the Traumatic Stress Disorder Reaction Index for children and adolescents (UCLA PTSD) Reaction Index for DSM-5 (PTSD-RI-5) in adolescents, a self-report instrument intended to screen for trauma exposure and assess PTSD symptoms. Method: Data was collected from 4201 adolescents in communities within eleven countries worldwide (i.e. Brazil, Bulgaria, Croatia, Indonesia, Montenegro, Nigeria, Palestine-Gaza, Philippines, Portugal, Romania, and Serbia). Internal consistency, discriminant validity, and a confirmatory factor analysis of a four-factor model representing the main DSM-5 symptoms of the PTSD-RI-5 were evaluated. Results: The PTSD-RI-5 total score for the entire sample shows very good reliability (α = .92) as well as across all countries included (α ranged from .90 to .94). The correlations between anxiety/depressive symptoms and the PTSD-RI-5 scores were below .70 indicating on good discriminant validity. The four-factor structure of the scale was confirmed for the total sample and data from six countries. The standardized regression weights for all items varied markedly across the countries. The lack of a common acceptable model across all countries prevented us from direct testing of cross-cultural measurement invariance. Conclusions: The four-factor structure of the PTSD-RI-5 likely represents the core PTSD symptoms as proposed by the DSM-5 criteria, but there could be items interpreted in a conceptually different manner by adolescents from different cultural/regional backgrounds and future cross-cultural evaluations need to consider this finding.

Antecedentes: Los niños y adolescentes a menudo están expuestos a eventos traumáticos, que pueden llevar al desarrollo de un trastorno de estrés postraumático (TEPT). Por lo tanto, es importante que los médicos examinen los posibles síntomas que pueden ser signos del inicio de un TEPT. Este trastorno en jóvenes es un problema global, por lo que se necesitan herramientas de detección congruentes en varios idiomas.Objetivo: El objetivo de este estudio fue probar en adolescentes las propiedades psicométricas generales del Índice de Reacción TEPT de la UCLA para el DSM-5 (PTSD-RI-5), que es un instrumento de auto-reporte destinado a evaluar la exposición al trauma y evaluar los síntomas de PTSD.Método: Los datos se recopilaron de 4201 adolescentes en comunidades dentro de once países alrededor del mundo (es decir, Brasil, Bulgaria, Croacia, Indonesia, Montenegro, Nigeria, Palestina-Gaza, Filipinas, Portugal, Rumania y Serbia). Se evaluó la consistencia interna, la validez discriminante y un análisis factorial confirmatorio de un modelo de cuatro factores que representa los principales síntomas del DSM-5 del PTSD-RI-5Resultados: La puntuación total de PTSD-RI-5 para toda la muestra reveló una muy buena confiabilidad (α = .92), así como en todos los países incluidos (α varió de .90 a .94). Las correlaciones entre los síntomas de ansiedad/depresión y las puntuaciones del PTSD-RI-5 fueron inferiores a .70, lo que indica una buena validez discriminante. La estructura de cuatro factores de la escala se confirmó para la muestra total y los datos de seis países. Las ponderaciones de regresión estandarizada variaron notablemente para todos los ítems en todos los países. La falta de un modelo aceptable común en todos los países nos impidió realizar pruebas directas de invariancia de medición intercultural.Conclusiones: La estructura de cuatro factores del PTSD-RI-5 probablemente representa los síntomas centrales del TEPT según lo propuesto por los criterios del DSM-5, pero podría haber elementos interpretados de manera conceptualmente diferente por adolescentes con diferentes orígenes culturales/regionales, y futuras evaluaciones interculturales deben considerar este hallazgo.

Nutritional status of Palestinian preschoolers in the Gaza Strip: a cross-sectional study.

BACKGROUND: The authors examined factors associated with nutritional resilience/vulnerability among preschoolers in the Gaza Strip in 2007, where political violence and deprivation are widespread. METHODS: This cross-sectional study was carried out in 2007 using random sampling of kindergartens in order to select 350 preschoolers. Binary logistic regression was used to compare resilient (adequate nutrition) and vulnerable (stunted) groups with those with moderate nutrition. RESULTS: Approximately 37% of the subjects demonstrated nutritional resilience and 15% were vulnerable. Factors associated with nutritional resilience were child younger age, normal birth weight, actively hand- or spoon-feeding when the child was below two years, and residential stability in the past two years. The only factor associated with nutritional vulnerability was lower total score on the mother's General Health Questionnaire, which we interpret as a marker of maternal mental health. CONCLUSIONS: Children with low-birth weight and older children had worse nutritional resiliency outcomes. Further, poorer outcomes for children were associated with lower maternal mental health status, as well as increased family residential instability. Our results add to the large literature on the pervasive effects of violence and instability on children and underscore the need for resources for early intervention and for the urgent resolution of the Palestinian and other armed conflicts.

Health-related quality of life of Palestinian preschoolers in the Gaza Strip: a cross-sectional study.

BACKGROUND: Research on children's responses to wartime trauma has mostly addressed Post-Traumatic Stress Disorder (PTSD). However, PTSD is only one aspect of a complex set of responses. This study proposes to expand knowledge of well-being in children exposed to political violence through widening the conceptualization of well-being beyond PTSD, morbidity, and mortality by measuring health-related quality of life (HRQOL) and its facets, physical health, and psychosocial health. METHODS: In 2007, we used a cross-sectional random sample of kindergartens to examine factors associated with HRQOL, as measured by the PedsQL 4.0, in 350 preschoolers in the Gaza Strip, Palestine, where political violence and deprivation are widespread. RESULTS: About 65% of the mothers reported severely impaired psychosocial and emotional functioning in their children. Preschoolers had lower HRQOL than the US reference sample and samples of children in other low income countries with large effect size. HRQOL was comparable to those of US children with several chronic diseases. Factors associated with lower HRQOL were older child age, male gender, and more exposures to traumatic events. Factors associated with HRQOL subscales were for lower psychosocial health: older child age, history of food, water, and electricity deprivation during incursion, and witnessing assassination of people by rockets. For lower physical health: older child age, history of food, water, and electricity deprivation during incursion, and having heard of a killing of a friend by soldiers. CONCLUSIONS: HRQOL, including psychosocial health and emotional functioning is often severely impaired among preschoolers in the Gaza Strip. Exposure to both violent and non-violent negative events was associated with HRQOL in preschoolers.
