Objective: To determine the prevalence and the associated psychological and social factors of occasional and repetitive deliberate self-harming behavior in adolescents.Design: Cross-sectional self-report survey.Setting: One hundred twenty-one schools in Germany.Participants: A representative sample of 5759 ninthgrade students was studied between 2004 and 2005.Outcome Measures: Deliberate self-harm (DSH) and suicidal behaviors, emotional and behavioral problems (Youth Self-Report), living standard, family composition, parental conflict and illness, school type and performance, relationship to peers, bullying, body satisfaction and dieting, media consumption, smoking, and alcohol and drug use.Results: Occasional forms of DSH within the previous year were reported by 10.9% of the ninth-grade students. Four percent of the students reported repetitive forms of DSH. Suicidal behavior was strongly associated with repetitive DSH, an association that held for both subtypes of DSH. The findings also indicated that social background factors were important concomitants of occasional DSH but were not related to an increased likelihood of repetitive DSH. Symptoms of depression/anxiety and delinquent/aggressive behavior were associated with selfharming behavior in both adolescent girls and boys.
Conclusions:The data suggest that there is a link between social factors and occasional DSH and, especially in repetitive DSH, that there is a strong association between DSH and suicidal behavior as well as DSH and emotional and behavioral problems. These findings indicate a different pathway in the development of DSH in adolescents. The results support a need to investigate the possible neurobiological underpinnings of DSH within a longitudinal model to enhance the knowledge of this poorly understood behavior.Arch Pediatr Adolesc Med. 2007;161(7):641-649
Our findings support the hypothesis of abnormal white matter microstructure of fronto-temporal cortical networks in ASD, which are associated with core symptoms of the disorder.
BackgroundWhile suicide is the second leading cause of death among young people in most industrial countries, non-fatal suicidal behaviour is also a very important public health concern among adolescents. The aim of this study was to investigate gender differences in prevalence and emotional and behavioural correlates of suicidal behaviour in a representative school-based sample of adolescents.MethodsA cross-sectional design was used to assess suicidal behaviour and various areas of emotional and behavioural problems by using a self-report booklet including the Youth Self-Report. One hundred sixteen schools in a region of Southern Germany agreed to participate. A representative sample of 5,512 ninth-grade students was studied. Mean age was 14.8 years (SD 0.73); 49.8% were female.ResultsSerious suicidal thoughts were reported by 19.8% of the female students and 10.8% of the females had ever attempted suicide. In the male group, 9.3% had a history of suicidal thoughts and 4.9% had previously attempted suicide. Internalizing emotional and behavioural problems were shown to be higher in the female group (difference of the group means 4.41) while externalizing emotional and behavioural problems slightly predominated in male students (difference of the group means -0.65). However, the total rate of emotional and behavioural problems was significantly higher in the adolescent female group (difference of the group means 4.98). Using logistic regression models with suicidal thoughts or attempted suicide as dependent variables, the pseudo-R2 of gender alone was only 2.7% or 2.3%, while it was 30% or 23.2% for emotional and behavioural problems measured by the YSR syndrome scales. By adding gender to the emotional and behavioural problems only an additional 0.3% of information could be explained.ConclusionsThe findings suggest that gender differences in non-fatal suicidal behaviour among adolescents can to a large extent be explained by the gender differences in emotional and behavioural problems during this age.
BackgroundBeing a victim of bullying in school is clearly linked to various social, emotional, and behavioral problems including self-harm behavior. However, it is not known whether even occasional victimization has similar negative consequences and whether protective factors such as social support may prevent those harmful developments. The present study therefore focuses on the nonsuicidal self-injury (NSSI) and suicidal behavior (SB) in victims of bullying and the potentially moderating effect of parental monitoring.MethodsIn all, a cross-sectional sample of 647 adolescents (mean age 12.8 years) were surveyed concerning bullying experiences, NSSI and SB, and parental monitoring.ResultsA total of 14.4 % of respondents reported being a victim of frequent bullying in the past few months (with verbal and social bullying playing the most important role), which increased the risks of both NSSI (OR = 11.75) and SB (OR = 6.08). This relationship could also be shown for occasional victims of bullying (35.6 %), although to a lesser extent. Parental monitoring had a significant protective effect on SB in victims of occasional bullying. However, parental monitoring did not show any protective effect in victims of repetitive bullying.ConclusionsVictims of bullying show a substantial risk for engaging in self-harm behavior. Therefore, the dissemination of anti-bullying programs in schools would probably also prevent such disorders. Parental participation in school-based prevention may increase its effect; this also matches the results of the present study, showing that parental monitoring may be able to buffer the negative effects of bullying victimization, at least to a certain degree.
Auditory temporal processing could be trained effectively at the sound and phoneme levels. However, no significant stable transfer of these improved abilities on reading and spelling exceeding the effect of the school-based standard training was demonstrated.
