Reducing violence and prejudice in a Jamaican all age school using attachment and mentalization theory

A study is reported of a psychoanalytic intervention in a very violent and prejudiced Jamaican school with disenfranchised children 7-9 grades who had failed academic streaming examinations. Over the period of 3 years of the intervention using mentalization and power issues approaches grounded in attachment theory, children were assisted to feel connected and valued by their school. There were striking improvements in academic performance, decreased victimization, and increased helpfulness especially in boys including significant trickle down effects to grades 1-6. Overall, the school became a place teachers wanted to join and the Jamaican government recognized their success and built a new school for them in a better location

Impact of Hurricane Rita on Adolescent Substance Use

Little systematic research attention has been devoted to the impact of natural disasters on adolescent substance use. The present study examined relationships among exposure to Hurricane Rita, post-traumatic stress (PTS) symptoms, and changes in adolescent substance use from 13-months pre-disaster to seven- and 19-months post-disaster. Subjects were 280 high school students in southwestern Louisiana who participated in a drug abuse prevention intervention trial prior to the hurricane. Two-thirds of participants were female and 68% were white. Students completed surveys at baseline (13 months pre-hurricane) and two follow-ups (seven-and 19-months post-hurricane). Results indicated a positive bivariate relationship between PTS symptoms, assessed at 7-months post-hurricane, and increases in alcohol (p < .05) and marijuana use (p <.10) from baseline to the 7-month post-hurricane follow-up. When these associations were examined collectively with other hurricane-related predictors in multivariate regression models, PTS symptoms did not predict increases in substance use. However, objective exposure to the hurricane predicted increases in marijuana use and post-hurricane negative life events predicted increases in all three types of substance use (p’s <.10). These findings suggest that increased substance use may be one of the behaviors that adolescents exhibit in reaction to exposure to hurricanes

Co-reminiscing with a caregiver about a devastating tornado: Association with adolescent anxiety symptoms

This study explores the association between caregivers’ style of co-reminiscing with their adolescents about an EF4 tornado and youth anxiety symptoms several years following the disaster. Caregiver reward of their children’s emotional expression, defined as attending to and validating emotionally salient content, is generally associated with adaptive youth psychosocial outcomes. However, caregiver reward of youth recollections that are centered around the youth’s negative emotional expression could be an indicator that both caregivers and adolescents are engaged in co-rumination regarding negative emotional experiences. This process may contribute to relatively higher levels of anxiety over time. Adolescents (N = 169) drawn from an ongoing study for aggressive youth (ages 12 to 17; 82% African American) provided individual recollections about their experiences during a devastating tornado 4 to 5 years following the disaster. Caregivers and youth then co-reminisced about their tornado-related experiences. Individual youth recollections were coded for negative personal impact and use of negative emotion words; caregiver–adolescent conversations were coded for caregiver reward of negative emotional expression. Youth who noted more negative personal impacts and used more negative emotion words were higher in parent-rated youth anxiety, and these associations were moderated by caregiver reward of negative emotional expression. The associations between youth recollection qualities and anxiety emerged only when caregivers exhibited high levels of reward of negative emotional expression. These patterns were generally stronger for girls compared to boys. Findings suggest that excessively discussing and rehashing negative experiences, especially several years after the disaster, may be a risk factor for anxiety among disaster-exposed adolescents

Creating a peaceful school learning environment: the impact of an antibullying program on educational attainment in elementary schools

The impact of a bullying and violence prevention program on education attainment was studied in five elementary schools (K-5), over a 5-year period.A multiple baseline design was used and academic attainment test scores of 1,106 students were monitored before and after the introduction of the program across the school district. This sample was contrasted with an equivalent control sample of 1, 100 students from the school district who attended schools that did not join the program.Program participation was associated with pronounced improvements in the students' achievement test scores. Notable reductions in the scores of those students who left schools with active programs were also observed.This simple, low-cost anti-violence intervention, involves all those who work in schools, not just students. It appears to significantly benefit educational performance of children in the participating elementary schools. The program focuses attention on the interaction between the bully, victim and audience of bystanders who are seen as pivotal in either promoting or ameliorating violence.Buy in to the philosophy by teachers & administration is high, because the format allows each school to create materials with its own personal stamp, and since there is no classroom curriculum add on, the burden to teachers is vastly reduced. Psychiatrists who work with schools could easily assist a school to put the program in place as part of their consultation work

Peer Deviance, Social Support, and Symptoms of Internalizing Disorders among Youth Exposed to Hurricane Georges

This study examined the influence of peers in meeting DSM-IV symptom criteria for an internalizing disorder in adolescents exposed to Hurricane Georges. Participants included a representative community sample of 905 youth (N = 476 boys) ages 11-17 residing in Puerto Rico. Data were gathered on hurricane exposure, symptoms of internalizing disorders, peer social support, peer violence, and peer substance use through in-person structured interviews with adolescents and caretakers from 1999-2000 in Puerto Rico, 12-27 months after Hurricane Georges. Hurricane exposure, peer violence, and peer substance use predicted whether adolescents met DSM-IV symptom criteria for a measured internalizing disorder. An interaction was found between hurricane exposure and peer violence, which indicated that hurricane exposure was significantly related to meeting DSM-IV symptom criteria for an internalizing disorder among adolescents who do not report associating with violent peers. However, for participants who reported high levels of peer violence, hurricane exposure did not convey additional risk for meeting DSM-IV symptom criteria for an internalizing disorder. With the increasing role peers play in adolescents’ lives, understanding the influence of peers on the development of internalizing symptoms following hurricane exposure may assist in planning developmentally sensitive response plans

A cluster randomized controlled trial of child-focused psychiatric consultation and a school systems-focused intervention to reduce aggression

While school-based anti-bullying programs are widely used, there have been few controlled trials of effectiveness. This study compared the effect of manualized School Psychiatric Consultation (SPC), CAPSLE (a systems and mentalization focused whole school intervention), and treatment-as-usual (TAU) in reducing aggression and victimization among elementary school children.Participants were 1,345 third to fifth graders in nine elementary schools in a medium-sized Midwestern city who took part in a cluster-level randomized controlled trial with stratified restricted allocation, to assess efficacy after two years of active intervention and effectiveness after one year of minimal input maintenance intervention. Outcome measures included peer and self-reports of bullying, bystanding, and mentalizing behavior and classroom behavioral observations of disruptive and off-task behavior.CAPSLE moderated the developmental trend of increasing peer-reported victimization (p < .01), aggression (p < .05), self-reported aggression (p < .05) and aggressive bystanding (p < .05), compared to TAU schools. CAPSLE also moderated a decline in empathy and an increase in the percent of children victimized compared to SPC (p < .01) and TAU conditions (p < .01). Results for self-reported victimization, helpful bystanding, and beliefs in the legitimacy of aggression did not suggest significantly different changes among the study conditions over time. CAPSLE produced a significant decrease in off-task (p < .001) and disruptive classroom behaviors (p < .01), while behavioral change was not observed in SPC and TAU schools. Superiority with respect to TAU for victimization (p < .05), aggression (p < .01), and helpful (p < .05) and aggressive bystanding (p < .01) were maintained in the follow-up year.A teacher-implemented school-wide intervention that does not focus on disturbed children substantially reduced aggression and improved classroom behavior

Children’s Postdisaster Trajectories of PTS Symptoms: Predicting Chronic Distress
