School attacks are attracting increasing attention in aggression research. Recent systematic analyses provided new insights into offense and offender characteristics. Less is known about attacks in institutes of higher education (e.g., universities). It is therefore questionable whether the term “school attack” should be limited to institutions of general education or could be extended to institutions of higher education. Scientific literature is divided in distinguishing or unifying these two groups and reports similarities as well as differences. We researched 232 school attacks and 45 attacks in institutes of higher education throughout the world and conducted systematic comparisons between the two groups. The analyses yielded differences in offender (e.g., age, migration background) and offense characteristics (e.g., weapons, suicide rates), and some similarities (e.g., gender). Most differences can apparently be accounted for by offenders’ age and situational influences. We discuss the implications of our findings for future research and the development of preventative measures.
Although effective treatments exist, obsessive-compulsive disorder (OCD) is, according to the views of patients and experts, still associated with chronicity, a term with no clear and consistent definition. To improve patient care and to foster research, a clear distinction between the various concepts of chronicity cited in the literature is crucial. The aim was thus to explicate central concepts related to courses and trajectories in OCD based on an explorative, scoping search of the existing literature. Our review revealed a considerable lack in content validity, as the concepts were operationalized inconsistently. Concepts related to symptom improvement were (complete) recovery, partial/full remission and partial/full response. Terms used in relation with symptom stability or worsening were chronic/continuous, intermittent and episodic course, waxing and waning, relapse, recurrence, deterioration and treatment-refractoriness. All concepts are explained and visualized as a result of the review. Further, based on authors' remarks, we present recommendations on how to enhance care for chronic OCD patients, namely training psychotherapists to apply CBT as intended, managing patient beliefs about disease and treatment, and adapting psychotherapy to OCD subtypes. Finally, we then propose a literature-based definition of treatment-refractory OCD.
We live in an aging society. The change in demographic structures poses a number of challenges, including an increase in age-associated diseases. Delirium, dementia, and depression are considered to be of particular interest in the field of aging and mental health. A common theory regarding healthy aging and mental health is that the highest satisfaction and best performance is achieved when a person's abilities match the demands of their environment. In this context, the person's environment includes both the physical and the social environment. Based on this assumption, this dissertation focuses on the investigation of non-pharmacological interventions that modify environmental factors in order to facilitate the prevention and treatment of mental disorders in older patients and their caregivers. The first part of this dissertation consists of two publications and deals with the prevention of postoperative delirium in elderly patients. The PAWEL study investigated the use of a multimodal, non-pharmacological intervention in the routine care of patients aged 70 years or older undergoing elective surgery. The intervention included an interdepartmental delirium prevention team, daily use of seven manualized “best practice” procedures, structured staff training on delirium, and the adaptation of the hospital environment to the patients’ needs. The second part of the dissertation used a meta-analysis to investigate whether technology-based interventions are a suitable form of support for informal caregivers of people with dementia. Subgroup analyses were conducted to examine the effect of different types of technology on caregiver burden and depressive symptoms. The following main results were found: The PAWEL study showed that the use of a multimodal, non-pharmacological intervention resulted in a significantly lower incidence rate of postoperative delirium and reduced days with delirium in the intervention group compared to the control group. However, this difference could not be observed in the group of patients undergoing elective cardiac surgery. The results of the meta-analysis showed that technology-based interventions offer a promising alternative to traditional “face-to-face” services. Significant effect sizes could be found in relation to both the burden and the depressive symptoms of caregiving relatives. These results provide further important information on the significant impact of non-pharmacological interventions that modify environmental factors on mental health, and support the consideration of such interventions in the prevention and treatment of mental disorders in both older patients and their caregivers.
Objective: This study assesses the short-term and intermediate effects of preschool training stimulating phonological awareness and letter-sound correspondence for children at risk of developing dyslexia. Moreover, we examined whether training reduced the frequency of subsequent dyslexic problems. Method: 25 children at risk of developing dyslexia were trained with Horen, Lauschen, Lernen 1 und 2 (Kuspert & Schneider, 2008; Plume & Schneider, 2004) by their kindergarten teachers and were compared with 60 untrained at-risk children. Results:The training revealed a significant short-term effect: The phonological awareness of trained at-risk children increased significantly over that of untrained at-risk children. However, there were no differences in phonological awareness, spelling, and reading ability between the first-graders in the training and control group. Furthermore, reading problems were reduced in the training group. Conclusions: In the future, phonological awareness as well as additional predictors should be included when identifying children vulnerable to developing dyslexia. Moreover, in order to prevent dyslexia, additional prerequisite deficits need to be identified, alleviated, and their effects evaluated.
Das Ziel der Doktorarbeit war die Entwicklung und Evaluation eines skillsbasierten primären Präventionsprogramms (Mainzer Schultraining zur Essstörungsprävention (MaiStep)) für partielle und manifeste Essstörungen. Dabei wurde die Wirksamkeit durch einen primären (Reduktion vorhandener Essstörungssymptome) und sekundären (assoziierte Psychopathologie) Zielparameter 3 und 12 Monate nach Durchführung des Trainings überprüft. Innerhalb der randomisiert kontrollierten Studie gab es zwei Interventionsgruppe und eine aktive Kontrollgruppe. 1.654 Jugendliche (weiblich/männlich: 781/873; mittleres Alter: 13.1±0.7; BMI: 20.0±3.5) konnten für die Studie, an zufällig ausgewählten Schulen in Rheinland-Pfalz, rekrutiert werden. Die Entwicklung des Präventionsprogramms basiert auf einem systematischen Literaturreview von 63 wissenschaftlichen Studien über die Prävention von Essstörungen im Kindes- und Jugendalter. Eine Interventionsgruppe wurde durch Psychologinnen/Psychologen und eine zweite durch Lehrkräfte angeleitet. Das in der aktiven Kontrollgruppe durchgeführte Sucht- bzw. Stresspräventionsprogramm wurde durch Lehrkräfte geleitet. MaiStep zeigte zur 3-Monatskatamnese keine signifikanten Effekte im Vergleich zur aktiven Kontrollgruppe. Allerdings zeigten sich nach 12 Monaten multiple signifikante Effekte zwischen den Interventions- und der aktiven Kontrollgruppe. Im Rahmen der Analyse des primären Parameters wurden in den Interventionsgruppen signifikant weniger Jugendliche mit einer partiellen Anorexia nervosa (CHI²(2) = 8.74, p = .01**) und/oder partiellen Bulimia nervosa (CHI²(2) = 7.25, p = .02*) gefunden. Im Rahmen der sekundären Zielparameter zeigten sich signifikante Veränderungen in Subskalen des Eating Disorder Inventory (EDI-2) Schlankheitsstreben (F (2, 355) = 3.94, p = .02*) und Perfektionismus (F (2, 355) = 4.19, p = .01**) sowie dem Body Image Avoidance Questionnaire (BIAQ) (F (2, 525) = 18.79, p = .01**) zwischen den Interventions- und der aktiven Kontrollgruppe. MaiStep kann somit als erfolgreiches Programm zur Reduktion von partiellen Essstörungen für die Altersgruppe der 13- 15-jährigen bezeichnet werden. Trotz unterschiedlicher Wirkmechanismen zeigten sich die Lehrkräfte im Vergleich zu den Psychologinnen/Psychologen ebenso erfolgreich in der Durchführung.
Trial registration MaiStep is registered at the German Clinical Trials Register (DRKS00005050).
Fragestellung: Ziel der Studie war die Überprüfung der Wirksamkeit einer vorschulischen Förderung der phonologischen Bewusstheit und der Buchstaben-Laut-Verknüpfung bei Kindern mit einem Risiko für die Entwicklung einer Lese-Rechtschreibstörung (LRS) unter Bedingungen, die sich am Alltag der Kindertagesstätten orientierten und somit auch bei einem breiten Einsatz des Programms eine relativ ökonomische Variante darstellen. Methodik: Die Risikokinder der Trainingsgruppe (n = 20) wurden über 11 Wochen mit den Programmen Hören, Lauschen, Lernen 1 und 2 (Küspert & Schneider, 2008; Plume & Schneider, 2004) von Erzieherinnen gefördert. Sie wurden einer nicht-geförderten Risiko-Kontrollgruppe (n = 43) hinsichtlich ihrer Lese- und Rechtschreibleistungen sowie der Häufigkeit von LRS von der 1. bis zur 3. Klasse gegenübergestellt. Dabei wurden neben den Daten regulär eingeschulter Kinder auch jene in die Analyse inkludiert, die vom Schulbesuch zurückgestellt wurden. Ergebnisse: Im 1. und 2. Grundschuljahr zeigten die trainierten Risikokinder im Lesen und Rechtschreiben einen mindestens tendenziellen Leistungsvorsprung gegenüber nicht-geförderten Risikokindern. Trainingseffekte zeigten sich ebenfalls in einer Reduktion der Anzahl von Kindern mit LRS bis Klasse 2, tendenziell auch in Klasse 3. Schlussfolgerung: Insgesamt sprechen die Befunde für die Wirksamkeit des Trainings in der primären Prävention von Lese-Rechtschreibschwierigkeiten bei Risikokindern unter alltagsnahen Bedingungen.
Leaking comprises observable behavior or statements that signal intentions of committing a violent offense and is considered an important warning sign for school shootings. School staff who are confronted with leaking have to assess its seriousness and react appropriately - a difficult task, because knowledge about leaking is sparse. The present study, therefore, examined how frequently leaking occurs in schools and how teachers identify leaking and respond to it. To achieve this aim, we informed teachers from eight schools in Germany about the definition of leaking and other warning signs and risk factors for school shootings in a one-hour information session. Teachers were then asked to report cases of leaking over a six- to nine-month period and to answer a questionnaire on leaking and its treatment after the information session and six to nine months later. Our results suggest that leaking is a relevant problem in German schools. Teachers mostly rated the information session positively and benefited in several aspects (e.g. reported more perceived courses of action or improved knowledge about leaking), but also expressed a constant need for support. Our findings highlight teachers' needs for further support and training and may be used in the planning of prevention measures for school shootings.
Background: There is an increasing awareness of the impact of parental risk perception on the weight course of the child and the parent's readiness to engage in preventive efforts, but only less is known about factors related to the parental perception of the right time for the implementation of preventive activities. The aim of this study was to examine parental perceptions of the appropriate time to engage in child weight management strategies, and the factors associated with different weight points at which mothers recognize the need for preventive actions.
Methods: 352 mothers with children aged 2-10 years took part in the study. We assessed mothers' perceptions of the actual and preferred weight status of their child, their ability to identify overweight and knowledge of its associated health risks, as well as perceptions of the right time for action to prevent overweight in their child. A regression analysis was conducted to examine whether demographic and weight related factors as well as the maternal general risk perception were associated with recognizing the need to implement prevention strategies.
Results: Although most of the parents considered a BMI in the 75th to 90th percentile a valid reason to engage in the prevention of overweight, 19% of the mothers were not willing to engage in prevention until their child reached the 97th percentile. Whereas the child's sex and the identification of an elevated BMI were significant predictors for parents' recognition of the 75th percentile as right point to engage in prevention efforts, an inability to recognize physical health risks associated with overweight silhouettes emerged as a significant factor predicting which parents would delay prevention efforts until a child's BMI reached the 97th percentile.
Conclusion: Parental misperceptions of overweight and associated health risks constitute unfavorable conditions for preventive actions. Feedback on the health risks associated with overweight could help increase maternal readiness for change.
As part of the POPS study (Potsdam prevention of eating disorders) 300 adolescents aged between 10 and 13 years completed questionnaires measuring satisfaction with weight and muscles, body change strategies and disturbed eating behavior. More than half of the girls and a third of the boys are dissatisfied with their weight. Nearly 70% of the male participants were unhappy with their muscles. Both forms of body dissatisfaction are influenced by similar sociocultural and psychological factors. While weight dissatisfaction leads to weight reduction strategies and disturbed eating, muscle dissatisfaction results in muscle enhancement methods. Potential harmful consequences of excessive muscle building techniques are discussed. The data emphasize the need for a sex-specific investigation of body dissatisfaction and its consequences. Body image aspects relevant to boys should be added to intervention and prevention approaches.
