Though studies of children and adolescents indicate that this age group is in risk for suffering from posttraumatic stress, research on this age group is still sparse. The objectives of this project are: (1) To investigate the prevalence of traumatic events and negative life events, and whether negative life events also can entail PTSD. (2) Whether the associations between psychosocial factors are gender dependent. And (3) what characterises adolescents having tried to commit suicide (4) to conduct cross-cultural analysis of the abovementioned associations. (5) To validate measures of traumatization for this age group. Method: the first four objectives will be studied through data, based on a questionnaire including a list of traumatic events and negative life events, and standardized questionnaires measuring traumatization and various psycho-social variables. Population: Eighth-graders from four European countries and a consecutive population of 6-18 year-olds in a clinical sample.
The overriding aim of the present PhD thesis was to contribute knowledge to the field of posttraumatic stress and psychological distress in children and adolescents; a field that is characterised by a great lack of epidemiological knowledge. The PhD thesis is comprised of six empirical papers taking different perspectives on the topic. All six papers address epidemiology in trauma exposure, posttraumatic stress, and psychological and social variables that have shown to influence the development of posttraumatic stress and psychological distress. All papers are mainly based on data collected in a total population of Faroese eighth graders (N=687), and the six papers use distinct data from a questionnaire, which is explained in the distinct papers.
Twenty per cent of the adolescents had life time posttraumatic stress disorder, and additionally 14 % had life time posttraumatic stress at a subclinical level. Female gender, living with a single parent, exposure to multiple trauma, and exposure to a potentially traumatic event were variables associated to an increased risk of posttraumatic stress in Faroese adolescents. A gender variation in relative risk of following posttraumatic stress after various trauma types was identified. Significant cross cultural variation in various measures amongs Faroese, Danish, Icelandic, and Lithuanian adolescents was identified. The variation was in: number of trauma exposure, type of trauma exposed to, prevalence of posttraumatic stress and the gender ratio in posttraumatic stress. The Faroese adolescents were at a higher risk of posttraumatic stress compared to adolescents from the neighbouring countries, and were highly exposed to severe childhood trauma. Cross cultural differences were also found in the distribution of attachment patterns among Faroese, Danish and Icelandic adolescents with PTSD. Psychological and social factors together with four trauma types events were found to account for 56 % of the variance in PTSD the Faroese adolescents. The contributing variables were: female gender, fearful attachment, lack of social support, rational and emotional coping, and exposure to serious accidents, past suicide attempts, physical abuse, and bullying In the Faroese population an a high risk group of approximately 5 % was identified. This population was characterized by high exposure to severe traumatic events and suffered from posttraumatic stress, negative affectivity and somatic symptoms. Another 14 %, mostly adolescent males, also suffered from posttraumatic stress, negative affectivity and somatic symptoms, and had high exposure to violent traumas. Finally possible psycho-social risk factors in 10 % of the Faroese adolescent population, who reported life time suicide attempt were identified, and showed gender differences. This study shows that assessment of trauma exposure and following posttraumatic stress in adolescents is an important subject for further research. Moreover it underlines the importance that clinicians and decision makers emphasise trauma, prevention and treatment.
