Parenting, head injury and aggression : predictive pathways of offending in male young offenders

Hodges, Emma January 2012 (has links)
Adolescence is a risk period for offending and head injury (HI), with rates of HI in young offender populations frequently exceeding those in the community. Poor parenting practices have been associated with increased risk of offending and development of reactive and proactive aggression. Preliminary research suggests HI may discriminate offender profiles within young offenders, but the influence of HI on offending alongside parenting and aggression is less well known. This study explored the relationships between parenting practices, reactive and proactive aggression, HI and offending in a sample of male young offenders from a Young Offender Institute (n=98) using self report data. A history of at least one HI was reported by 73.5%, with 61.1% reporting a knock out from their worst HI. Poor supervision emerged as a key predictor: predicting knock out history, indicators of offending and reactive and proactive aggression. Repeated HI was predictive of reactive aggression and a knock out history predicted earlier age of first offence. The impact of HI on outcomes via neuropsychological sequelea or as a “marker” for contextual risk factors such as poor supervision and reactive aggression are examined. Clinical implications for young offenders are discussed.

The Emotional Guardianship of Foreign-Born and Native-Born Hispanic Youth and Its Effect on Violent Victimization

Eggers, Amy Sheena 16 September 2010 (has links)
This study seeks to expand the scope of assimilation theory by integrating it with elements of routine activities theory to better understand what influence assimilation has in regard to violent victimization. Specifically, the purpose of this study is to determine whether or not differences in victimization rates between foreign-born and native-born Hispanic youth are related to variations in emotional guardianship. Emotional guardianship refers to the aspect of relationships (i.e., affection and communication) between Hispanic youth and their parents that serve to protect the youth from being victimized. I hypothesize that foreign-born Hispanics have greater emotional guardianship than native-born Hispanics, and as a result foreign-born Hispanics have lower probabilities of victimization. To test this hypothesis and others, the National Longitudinal Study of Adolescent Health (Add Health) is utilized, as it provides data about the various aspects of assimilation (e.g., country of birth, language spoken at home), routine activities (e.g., sports, clubs, and family outings), and emotional guardianship (e.g., communication of problems, expectations, and satisfaction of parental bond), which are each believed to contribute to the likelihood of being victimized.

Relationship between the amount of parental supervision time and child delinquency.

Bessa, Yawo Agbessi 05 1900 (has links)
This study assesses the relationship between parental supervision and children's delinquency. Data used in this study came from interviews with 99 parents from the Denton city area of Texas in 2003. A probability sample of 53 was contacted by way of randomly selected residential telephone numbers. In addition, 46 parents were non-randomly selected. Parents were asked about how much time they spent supervising and engaging in activities with their children and whether or not the oldest child exhibited delinquent behavior such as fighting, playing hooky, and being sent to detention or the principal's office. The study found that the more time parents spend in supervision and in engaging activities with their daughters, the less likely these children were to exhibit delinquent behavior. This was consistent with previous research. However, the level of delinquency of boys increased with the increase in the amount of parental supervision time, especially by fathers.

Le stress prénatal maternel et les problèmes comportementaux chez les enfants : effet modérateur de la consistance de la discipline

Daniel, Benjhyna 03 1900 (has links)
Le stress prénatal maternel (SPM) est un concept largement étudié et ce, autant par de méthodes objectives que subjectives. Certains chercheurs évaluent les symptômes d’anxiété et de dépression des femmes au cours de leur grossesse alors que d’autres préfèrent mesurer les niveaux de cortisol des femmes enceintes. Pour cette thèse, le SPM a été mesuré par deux méthodes différentes, soit l’exposition des femmes enceintes à une catastrophe naturelle et l’exposition des mêmes femmes enceintes à des événements de vie stressants plus courants. Puisqu’il est bien établi que ce type de stress engendre des répercussions négatives sur la femme enceinte ainsi que sur le développement de l’enfant, il est désormais d’intérêt d’accentuer les recherches sur les moyens qui permettent d’atténuer les conséquences d’un tel stress. Dans les études auprès des animaux, nous savons que les conditions de maternage ainsi que l'enrichissement environnemental semblent renverser les effets du SPM, mais nous ne savons pas si, chez les humains, un bon encadrement parental, c’est-à-dire un cadre structuré avec des règles prévisibles et consistantes, peut protéger les enfants des effets du SPM. L’objectif de cette thèse est donc d’augmenter notre compréhension sur l’effet protecteur de l’encadrement parental dans le développement d’enfants qui ont été exposés à différents types de SPM. Cet objectif pourra être atteint grâce à une collaboration internationale initiée par la Dre Suzanne King suite aux inondations qui se sont produites en 2008 dans l'état d'Iowa. Suite à la catastrophe, la Dre King est entrée en contact avec le Dr O’Hara afin d'évaluer la sévérité du stress dû aux inondations chez les femmes enceintes et pour déterminer les effets de ce stress sur leur enfant. Trois types de stress ont été évalués: le degré objectif de difficulté (p. ex., pertes financières), l'évaluation cognitive de la catastrophe en tant qu'expérience négative, neutre ou positive, et la détresse subjective causée par l'inondation (p. ex., symptômes de TSPT). Suite au recrutement des mères, les enfants de l'échantillon ont été évalués à l’âge de 2, 4, 5 et 7 ans. La présente thèse est composée de trois études. La première étude porte sur l’effet modérateur de l’encadrement parental sur les associations entre le SPM causé par les inondations d’Iowa et les problèmes comportementaux chez les enfants âgés de sept ans. Les résultats indiquent qu’un encadrement parental où la discipline est consistante protège les garçons qui ont été exposés au SPM objectif contre différents symptômes de problèmes internalisés et externalisés. La deuxième étude se penche également sur la question de l’effet protecteur de l’encadrement parental sur les associations entre le SPM et les problèmes comportementaux chez les enfants âgés de sept ans. Toutefois, cette étude s’est plutôt penchée sur l’influence du SPM lorsque celui-ci est causé par des événements de vie qui sont plus communs qu’un désastre naturel. De nouveau, les résultats de cette étude nous révèlent qu’un encadrement parental consistant joue le rôle de facteur de protection, chez les garçons qui ont été exposés au SPM causé par des événements de vie stressants, mais seulement en ce qui concerne les problèmes de comportement externalisés. La troisième étude vient reconsidérer l’effet protecteur de l’encadrement parental sur les liens entre le SPM et les problèmes comportementaux des enfants qui ont été exposés à un désastre naturel. Cependant, pour cette étude, les comportements des enfants n’ont pas été évalués par un questionnaire, mais plutôt par une méthode observationnelle (tâche de frustration). Toutefois, dans cette étude, il n’est ressorti aucun effet significatif de l’encadrement parental comme variable modératrice. En somme, nos résultats rapportent que l’implantation d’un cadre structuré et consistant peut venir pallier et même renverser les conséquences du SPM sur le comportement des garçons. / Prenatal maternal stress (PNMS) is a widely studied concept, both by objective and subjective methods. Some researchers assess women's symptoms of anxiety and depression during pregnancy, while others prefer to measure cortisol levels in pregnant women. For this thesis, PNMS was measured by two different methods: either exposure of pregnant women to a natural disaster, or exposure of these same pregnant women to more common stressful life events. Since it is well established that this type of stress has a negative impact on the pregnant woman as well as on the development of the unborn child, it is now of interest to increase research on ways to mitigate the consequences of such stress. In animal studies, we know that rearing conditions and environmental enrichment seem to reverse the effects of PNMS, but we do not know whether, in humans, good parental structure, that is, a structured framework with predictable and consistent rules, can protect children from the effects of PNMS. The aim of this thesis is, therefore, to increase understanding of the protective effect of parental structure in the development of children who have been exposed to different types of PNMS. This goal can be achieved through an international collaboration initiated by Dr. Suzanne King following the 2008 floods in the state of Iowa. Following the disaster, Dr. King contacted Dr. O'Hara to assess the severity of flood stress in pregnant women and to determine the effects of this stress on their children. Following the recruitment of mothers, the children in the sample were assessed at the ages of 2, 4, 5 and 7 years. This thesis consists of three studies. The first study examines the moderating effect of parental structure on the associations between PNMS caused by a natural disaster and behavioural problems in the Iowa Flood Study children at age 7 years as reported by their mothers. The results indicate that consistent parenting protects boys who have been exposed to PNMS from various symptoms of internalizing and externalizing problems. The second study also examines the issue of the protective effect of parental structure on associations between PNMS and behavioural problems, as reported by their mothers, in the Iowa Flood Study seven-year-olds. However, this study looked at the influence of PNMS when it is caused by life events that are more common than a natural disaster while controlling for the severity of their flood exposure. Again, the results of this study reveal that consistent parenting plays the role of a protective factor in boys who have been exposed to PNMS caused by stressful life events, but only with regard to externalizing behaviour. The third study reconsiders the protective effect of parental structure on the links between PNMS and behavioral problems of children who have been exposed to a natural disaster. However, for this study, children's behaviors were not assessed by a questionnaire, but rather by an observational method (task of frustration). However, the limitations of this study did not allow us to observe the effects of parental structure. In summary, our results show that the implementation of a structured and consistent framework can overcome, and even reverse, the consequences of PNMS on boys' behaviour.
