Over the past decade, the University of California at Los Angeles Post-traumatic Stress Disorder Reaction Index has been one of the most widely used instruments for the assessment of traumatized children and adolescents. This paper reviews its development and modifications that have been made as the diagnostic criteria for post-traumatic stress disorder have evolved. The paper also provides a description of standard methods of administration, procedures for scoring, and psychometric properties. The Reaction Index has been extensively used across a variety of trauma types, age ranges, settings, and cultures. It has been broadly used across the US and around the world after major disasters and catastrophic violence as an integral component of public mental health response and recovery programs. The Reaction Index forms part of a battery that can be efficiently used to conduct needs assessment, surveillance, screening, clinical evaluation, and treatment outcome evaluation after mass casualty events.

    • "Trauma History Profile (THP) The Trauma History component of the UCLA PTSD Reaction Index (UCLA PTSD-RI; Steinberg et al. 2004) was used to obtain information about potentially traumatic events and other adverse childhood experiences (hereafter referred to as ACEs) from multiple informants , including the child or adolescent, parents/caregivers, and other relatives. The resultant THP includes information on 17 variables (see Table 2). "

    ABSTRACT: By the time children reach adolescence, most have experienced at least one type of severe adversity and many have been exposed to multiple types. However, whether patterns of adverse childhood experiences are consistent or change across developmental epochs in childhood is not known. Retrospective reports of adverse potentially traumatic childhood experiences in 3 distinct developmental epochs (early childhood, 0- to 5-years-old; middle childhood, 6- to 12-years-old; and adolescence, 13- to 18-years-old) were obtained from adolescents (N = 3485) referred to providers in the National Child Traumatic Stress Network (NCTSN) for trauma-focused assessment and treatment. Results from latent class analysis (LCA) revealed increasingly complex patterns of adverse/traumatic experiences in middle childhood and adolescence compared to early childhood. Depending upon the specific developmental epoch assessed, different patterns of adverse/traumatic experiences were associated with gender and with adolescent psychopathology (e.g., internalizing/externalizing behavior problems), and juvenile justice involvement. A multiply exposed subgroup that had severe problems in adolescence was evident in each of the 3 epochs, but their specific types of adverse/traumatic experiences differed depending upon the developmental epoch. Implications for research and clinical practice are identified.

    • "Previous studies reported good internal consistency (Cronbach's alpha around .90) and test–retest reliability (between .84 and .93) across UCLA PTSD-RI versions (Rodriguez, Steinberg, & Pynoos, 1999; Roussos et al., 2005; Steinberg, Brymer, Decker, & Pynoos, 2004). The Chinese adolescent version of the UCLA PTSD-RI has showed satisfactory internal consistency accidents, with Cronbach's alpha ranging from .88 to .94 (Shen, 2009; Wang, 2002). "

    ABSTRACT: This study used the data from a representative sample to estimate the prevalence of child bullying victimization in Xi'an, China. Data on social demographic information and the experiences of different types of bullying victimization were collected from a randomly selected sample with 3,175 middle school students aged 15-17 years by self-administrated questionnaires. t Test, χ(2) test, and multiple logistic regression analyses were used to test group differences and examine the correlates of bullying victimization. Results show that 54.9% and 44.6% of Chinese children have been bullied in a lifetime and in the preceding year, respectively. Correlates for direct and relational bullying victimization includes male participants, father's lower education level, father's unemployment, having one or more siblings, smoking, depression, borderline personality trait, posttraumatic stress disorder, and from rural schools. Overall, the prevalence of child bullying victimization in China is substantial. The multiple correlates suggest prevention and intervention of bullying victimization in a holistic and comprehensive way.

    • "Summary scores range from 0 to 68, with higher scores indicating more severe levels of PTS symptomology. This measure has exhibited good psychometric properties (Steinberg et al. 2004) and has been utilized throughout the postdisaster research (Kelley et al. 2010; Self- Brown et al. 2013; Weems et al. 2010; Yelland et al. 2010). Internal consistency was good for this sample (α=0.92). "

    ABSTRACT: The authors examined depression trajectories over two years among mothers exposed to Hurricane Katrina. Risk and protective factors for depression trajectories, as well as associations with child outcomes were analyzed. This study included 283 mothers (age at time 1, M = 39.20 years, SD = 7.21; 62 % African American). Mothers were assessed at four time points over two years following Hurricane Katrina. Mothers reported posttraumatic stress symptoms, hurricane exposure, traumatic life events, and social support at time 1. Depressive symptoms were modeled at times 2, 3, and 4. Youth reported their distress symptoms (posttraumatic stress, depression, and anxiety) at time 4. Latent class growth analyses identified three maternal depression trajectories among mothers exposed to Hurricane Katrina: low (61 %), resilient (29 %), and chronic (10 %). Social support was identified as a protective factor among mothers. Three main trajectories of maternal depression following Hurricane Katrina were identified. Social support was protective for mothers. Identified trajectories were not associated with children’s distress outcomes. These results have implications for disaster responses, screening efforts, and interventions targeted towards families. Future studies warrant the investigation of additional risk and protective factors that can affect maternal and child outcomes.
