Longitudinal relations of prematurity and fetal growth restrictions with hyperactivity/inattention and aggression/delinquency.

BACKGROUND: It is the aim of this study to analyze the longitudinal relationship between premature birth and low birth weight and the reciprocal influence between hyperactive/inattentive behavior and aggressive/delinquent behavior problems in children from early to late childhood. METHODS: This study contains data from the German Erlangen-Nuremberg Development and Prevention Study. It applies prospective longitudinal path analyses on data obtained from postnatal pediatric assessments as well as later psychosocial behavior assessments by teachers and parents on N = 667 children, out of which n = 83 children (12.44%) were born preterm/small for gestational age. RESULTS: The results show direct effects of birth complications at the beginning of preschool on hyperactivity/inattentiveness (teacher rating: ß = 0.28; p = 0.017; parent rating: ß = 0.32; p = 0.005), but not on aggression/delinquency (teacher rating: ß = 0.002; p = 0.427; parent rating: ß = 0.12; p = 0.324). Reciprocal effects between aggression/delinquency and hyperactivity/inattentiveness were stable at the end of elementary school, but not at the end of preschool across informants. CONCLUSION: Our results support a differentiated view on the potential development of behavior problems after birth complications and the demand for early prevention measures. IMPACT STATEMENT: Our results extend to the existing body of research by providing insight into the longitudinal effects of prematurity and fetal growth restrictions on hyperactive and aggressive/delinquent behavioral problems throughout a rather long period of development in childhood. The results show direct effects of birth complications on the development of hyperactivity for boys, but not for girls across informants. No direct effects of birth complications on aggression/delinquency are found. Our findings speak against too simple views on behavioral consequences of birth complications and thus can relieve too anxious parents, however close monitoring of the behavioral development of respective children is indicated.

Psychosocial prevention programs against radicalization and extremism: a meta-analysis of outcome evaluations / Programas de prevención psicosocial contra la radicalización y el extremismo: meta-análisis de las evaluaciones de los resultados

Politically, religiously, and otherwise motivated radicalization and violent extremism is a topic of high priority in many countries. Therefore, beyond intelligence and police measures, there is a strong increase of psychosocial prevention programs in this field. However, little is known about their effectiveness. We aimed to fill this research gap by conducting a systematic international review and meta-analysis of outcome evaluations. We screened about 14,000 reports on the topic of extremism prevention, but in spite of broad criteria of eligibility, we only found nine more or less well-controlled outcome evaluations from seven countries. Six programs addressed religious/ethnic extremism, one targeted nationalist/separatist extremism, and one different types of extremism. Most evaluations had a quasi-experimental pre-post design, only one contained a randomized controlled trial (RCT). Overall, programs had a significant mean positive effect on behavioral and psychosocial outcomes related to extremism (d = 0.50, SE = 0.12). Regarding the specific effects of the programs on psychosocial aspects such as for example extremist attitudes alone, we found similar results (d = 0.56, SE = 0.11). We found stronger effects for programs with target groups from mixed ethnic backgrounds and approaches addressing both at-risk individuals and participants from the general population. Despite these promising results, the low internal validity of most evaluations and small number of eligible studies limit generalization. More high-quality evaluations are clearly needed. These would help to allocate resources in an evidence-oriented manner and provide a better understanding of the mechanisms of successfully preventing radicalization and violent extremism

La radicalización y el extremismo violento por causas políticas, religiosas o de otro tipo es un tema prioritario en muchos países. Además, más allá de las medidas de servicios de inteligencia y policiales, hay un aumento de los programas de prevención psicosocial en este campo. Sin embargo, no se sabe mucho de su eficacia. Para llenar este vacío en la investigación llevamos a cabo una revisión sistemática internacional y un meta-análisis de la evaluación de los resultados. Revisamos alrededor de 14,000 informes sobre prevención del extremismo, pero a pesar de que utilizamos un criterio de selección de artículos amplio solo encontramos nueve evaluaciones de resultados más o menos bien controladas de siete países. Seis programas abordaban el extremismo religioso/étnico, uno el nacionalista/separatista y uno consistía en un ensayo controlado aleatorizado (ECA). En general, los programas mostraron un efecto promedio positivo y significativo en los resultados comportamentales y psicosociales relacionados con el extremismo (d = 0.50, SE = 0.12). En cuanto a los efectos específicos de los programas en las dimensiones psicosociales, tal como las actitudes extremistas, encontramos unos efectos similares (d = 0.56, SE = 0.11). Hallamos efectos mayores en los programas con grupos diana de antecedentes étnicos mixtos y enfoques que se dirigían tanto a sujetos en riesgo como a participantes de la población general. A pesar de unos resultados prometedores, la escasa validez interna de la mayoría de las evaluaciones y el bajo número estudios que cumplían los criterios de selección limitan la generalización. En consecuencia, se necesitan más estudios con diseños de buena calidad. Estos ayudarían a asignar los recursos sobre la base de evidencia científica y proporcionarían una mejor comprensión de los mecanismos de prevención con éxito del extremismo violento y la radicalización

Adrenocortical Activity and Aggressive Behavior in Children: A Longitudinal Study on Risk and Protective Effects.

Most research on aggression and delinquency concentrates on risk factors. There has been less attention for protective factors and mechanisms, in particular with regard to biosocial influences. Based on theories of autonomous arousal and stress reactance the present study addresses the influence of adrenocortical activity as a risk and/or protective factor in the development of antisocial behavior in children. We also investigated relations to anxiousness and family stressors. In a prospective longitudinal study of 150 German boys, the first measurement took place at preschool age and contained an assessment of cortisol after waking up and 30 min later. Aggressiveness and anxiousness of the children were assessed by the kindergarten teachers with the Social Behavior Questionnaire. After 6 years, the children's behavior was rated by the teachers in middle school. Variable-oriented data analyses revealed a significant correlation between the total amount of cortisol after waking up and 30 min later (AUC G ) and anxiousness both cross-sectionally and longitudinally, but not with aggressiveness. A family stress index correlated positively with aggressiveness but neither with cortisol nor with anxiousness. There were significant correlations between aggressiveness and anxiousness at kindergarten age and the respective behavior problems 6 years later. In a linear regression analysis on aggression only family stress had a significant effect but anxiousness not. Moderator analyses on aggressiveness with anxiousness and AUC G or on AUC G with anxiousness and aggressiveness did not show any significant interactions. Longitudinally, only aggression significantly predicted aggression 6 years later in a linear regression. In addition to variable-oriented analyses, we also applied a person-oriented approach to investigate specific patterns of behavior. Children who were high in both aggressiveness and anxiousness had the highest cortisol level and those with low anxiousness and high aggressiveness the lowest. The groups with different patterns of externalizing and internalizing problems at preschool age showed significant differences in aggression 6 years later. Our results underline the need for complex pattern analyses on cortisol, aggression, and anxiousness in children and for a differentiated consideration of emotional reactive aggression and unemotional instrumental aggression.

On the Effectiveness of Sexual Offender Treatment in Prisons: A Comparison of Two Different Evaluation Designs in Routine Practice.

Although there is less continuity of sexual offending in the life course than stereotypes suggest, treatment should lead to a further reduction of reoffending. Contrary to this aim, a recent large British study using propensity score matching (PSM) showed some negative effects of the core sex offender treatment program (SOTP) in prisons. International meta-analyses on the effects of sex offender treatment revealed that there is considerable variety in the results, and methodological aspects and the context play a significant role. Therefore, this study compared different designs in the evaluation of sex offender treatment in German prisons. PSM was compared with an exact matching (EM) by the Static-99 in a sample of 693 sex offenders from Bavarian prisons. Most results were similar for both methods and not significant due to low base rates. There was a treatment effect at p < .05 on general recidivism in the EM and at p = .06 on serious reoffending in the PSM. For sexual recidivism, EM showed a negative trend, whereas PSM suggested the opposite. Overall, the study underlines the need for more replications of evaluations of routine practice, methodological comparisons, sensitive outcome criteria, and differentiated policy information.

Bullying at school as a predictor of delinquency, violence and other anti-social behaviour in adulthood.

BACKGROUND: Although bullying at school is an important topic, its long-term relation to anti-social development is rarely investigated. AIM: To study the relation between bullying in youth and anti-social outcomes in adulthood. METHODS: A group of 63 males (bullies and victims over-sampled) from the Erlangen-Nuremberg Bullying Study were investigated at ages 15 and 25. Bullying was assessed with the Olweus Bully/Victim Questionnaire. Outcome measures included self-reported delinquency, violence, aggressiveness, drug use, impulsivity and psychopathy. In addition to bivariate correlations, hierarchical regressions were used to control for family and individual risk factors. RESULTS: Bullying was a strong predictor of nearly all anti-social outcomes. Physical bullying was more predictive than verbal/indirect bullying. Controlling for family risks and externalising/internalising problems reduced effect sizes, but bullying remained a sound predictor. Victimisation was not related to anti-social outcomes. CONCLUSIONS: Bullying seems to be a key risk marker for anti-social development. Therefore, studies on whole-school anti-bullying programmes and child-oriented or family-oriented strategies of crime prevention should be more integrated.
