Timing and chronicity of child maltreatment in Germany: results from a representative sample.

OBJECTIVES: Child maltreatment (CM) is a major risk factor across the lifespan. While research on CM and its consequences has risen strongly during the last decades, research is mainly focused on the prevalence of types of CM incidents. As valid prevalence rates on timing and chronicity of CM are lacking to date, we aimed to assess the timing of experienced CM by describing the age of onset, duration, and prevalence at each year of age for each CM subtype in a population-based sample. STUDY DESIGN: Cross-sectional, observational study in a representative sample. METHODS: Using different sampling steps including a random route procedure, a probability sample of the German population above the age of 16, encompassing 2514 persons (50.6% female, mean age: 50.08 years) was generated. Participants were asked about sociodemographic information in a face-to-face interview, CM was assessed using the ICAST-R questionnaire. RESULTS: The earliest mean age of onset was seen in neglect with 8.07 (±3.07) years for boys and 7.90 (±2.96) years for girls, while the mean age of onset for sexual abuse was in adolescence with 13.65 (±3.86) years for boys and 13.91(±3.17) years for girls. The overall duration of CM was lowest for sexual abuse with 2.12 (±2.01) years for boys and 2.35 (±1.73) years for girls, the highest duration was seen for emotional abuse with 4.00 (±3.54) years for boys and 4.21 (±3.77) years for girls. CONCLUSIONS: Our novel results provide important epidemiological information for prevention efforts.

[Discharge management in pediatric and adolescent psychiatry : Expectations and realities from the parental perspective]. / Entlassmanagement in der Kinder- und Jugendpsychiatrie : Erwartungen und Realitäten aus Sicht der Eltern.

BACKGROUND: Interface management after inpatient care for mentally ill children and adolescents has been proven to be a breaking point in good transition of care between child and adolescent psychiatry, social welfare services, schools, job centre and the judicial system. Criteria for successful discharge management do not exist in child and adolescent psychiatry. Aim of the study ASpeKT was to survey parents on their perception of interface management and to derive recommendations for discharge management. METHODS: Data regarding interface management were retrieved from parents (T3, n = 124, T4, n = 81) 6 months (T3) and 12 months (T4) after discharge. RESULTS: The parents stated that accessible help after discharge from inpatient treatment is essential for stability and requires a good coordination. Parents named that they perceived helpful for successful interface management: a case manager, early round table meetings, support in returning to school, seamless access to outpatient follow-up appointments as well as information on further treatment options and contact data. CONCLUSION: From the perspective of affected families a proactive early individual and reliable care coordination by a constant contact person is essential for a good discharge management.

[Prevention for children with parents with depression or anxiety : National and international approaches and their age specificity]. / Prävention bei Kindern mit depressiven oder angsterkrankten Eltern : Nationale und internationale Ansätze und deren Altersspezifizität.

BACKGROUND: Children of mentally ill parents are exposed to a multitude of burdens due to the diseases of their parents. Age-related preventive measures and interventions are needed to minimize the risk for the development of psychiatric disorders by the children themselves. OBJECTIVE: The aim of the study was the documentation of preventive options on a national and international level for children of different age groups between 3 and 14 years with parents with depressive or anxiety disorders. MATERIAL AND METHODS: A systematic literature search was conducted to identify current evidence-based preventive interventions measures for these target groups and analyzed with respect to age-specific aspects and evidence. RESULTS: From screening 107,573 publications 43 interventions could be found. After examining the evidence of the interventions 25 projects could be included in the analysis For each of the different age groups the intervention with the best evidence is presented in this article. CONCLUSION: Many interventions were found but most of them were not sufficiently evaluated or psychometrically defined; however, the few well-evaluated evidence-based projects for children mostly addressed the age-specific needs. Projects for preschool age children mostly worked with the parents and referred to elements of parental training. For schoolchildren there were various preventive projects that especially worked with increasing the self-esteem and the development of coping strategies. Projects for adolescents worked with psychoeducation and increasing social connectedness. Across all age groups there was no comprehensive and cross-system networking between the interventions.

[Children of mentally ill parents : Also a topic in the context of child protection]. / Kinder psychisch erkrankter Eltern : Auch ein Thema im Rahmen des Kinderschutzes.

BACKGROUND: Severe mental illness in parents increases the risk of neglect, physical and sexual abuse (adverse childhood experiences, ACE) of children. OBJECTIVE: Presentation of the current situation of child protection issues in psychiatric care in Germany and the derivation of needs and potential solution strategies. MATERIAL AND METHODS: Based on a selective literature search, the needs and the current situation in Germany are presented and potential solution strategies are pointed out. The analysis is supplemented by a descriptive evaluation of specific consultation requests to the medical child protection hotline, which were descriptively evaluated and served as a starting point for the selective literature search. RESULTS: Despite the well-known comprehensive influence of mental illnesses of parents on their children, psychiatric patients have not yet been systematically registered regarding whether they have to care for underage children. There is a lack of systematic and comprehensive support for families at risk. Of all calls to the project medical child protection hotline, calls from the field of adult psychiatry and psychosomatics make up by far the highest proportion from the field of adult medicine. CONCLUSION: An increased awareness of child protection issues is necessary in the field of adult psychiatric treatment. Systematic counselling services for acute cases and also networking and structured cooperation with other medical fields, such as child and youth psychiatry, pediatrics and child and youth welfare should be addressed.

Psychosocial interventions for children and adolescents after man-made and natural disasters: a meta-analysis and systematic review.

Children and adolescents are a vulnerable group to develop post-traumatic stress symptoms after natural or man-made disasters. In the light of increasing numbers of refugees under the age of 18 years worldwide, there is a significant need for effective treatments. This meta-analytic review investigates specific psychosocial treatments for children and adolescents after man-made and natural disasters. In a systematic literature search using MEDLINE, EMBASE and PsycINFO, as well as hand-searching existing reviews and contacting professional associations, 36 studies were identified. Random- and mixed-effects models were applied to test for average effect sizes and moderating variables. Overall, treatments showed high effect sizes in pre-post comparisons (Hedges' g = 1.34) and medium effect sizes as compared with control conditions (Hedges' g = 0.43). Treatments investigated by at least two studies were cognitive-behavioural therapy (CBT), eye movement desensitization and reprocessing (EMDR), narrative exposure therapy for children (KIDNET) and classroom-based interventions, which showed similar effect sizes. However, studies were very heterogenic with regard to their outcomes. Effects were moderated by type of profession (higher level of training leading to higher effect sizes). A number of effective psychosocial treatments for child and adolescent survivors of disasters exist. CBT, EMDR, KIDNET and classroom-based interventions can be equally recommended. Although disasters require immediate reactions and improvisation, future studies with larger sample sizes and rigorous methodology are needed.

Alterations of hair cortisol and dehydroepiandrosterone in mother-infant-dyads with maternal childhood maltreatment.

BACKGROUND: Child maltreatment (CM) has severe effects on psychological and physical health. The hypothalamic-pituitary-adrenal (HPA) axis, the major stress system of the body, is dysregulated after CM. The analysis of cortisol and dehydroepiandrosterone (DHEA) in scalp hair presents a new and promising methodological approach to assess chronic HPA axis activity. This study investigated the effects of CM on HPA axis activity in the last trimester of pregnancy by measuring the two important signaling molecules, cortisol and DHEA in hair, shortly after parturition. In addition, we explored potential effects of maternal CM on her offspring's endocrine milieu during pregnancy by measuring cortisol and DHEA in newborns' hair. METHODS: CM was assessed with the Childhood Trauma Questionnaire (CTQ). Cortisol and DHEA were measured in hair samples of 94 mothers and 30 newborns, collected within six days after delivery. Associations of maternal CM on her own and her newborn's cortisol as well as DHEA concentrations in hair were analyzed with heteroscedastic regression models. RESULTS: Higher CM was associated with significantly higher DHEA levels, but not cortisol concentrations in maternal hair. Moreover, maternal CM was positively, but only as a non-significant trend, associated with higher DHEA levels in the newborns' hair. CONCLUSIONS: Results suggest that the steroid milieu of the mother, at least on the level of DHEA, is altered after CM, possibly leading to non-genomic transgenerational effects on the developing fetus in utero. Indeed, we observed on an explorative level first hints that the endocrine milieu for the developing child might be altered in CM mothers. These results need extension and replication in future studies. The measurement of hair steroids in mothers and their newborns is promising, but more research is needed to better understand the effects of a maternal history of CM on the developing fetus.

[Diagnostics and initial estimation of refugee minors]. / Diagnostik und Ersteinschätzung bei minderjährigen Flüchtlingen.

The number of underage refugees arriving in Germany has rapidly increased since 2015. Many of these children and adolescents have been and still are, exposed to a large number of stressful circumstances. The group of those helping refugee minors is heterogeneous with both volunteers and professional workers from the fields of child welfare and healthcare services. Easily applicable instruments to assess both burdens and resources are needed in order to plan appropriate interventions. This paper focuses on instruments for assessing the circumstances of refugee minors and includes pilot data of an online-based screening instrument to assess burdens and resources (providing online resource and trauma assessment for refugees, PORTA). Field application was tested by the staff of a clearing and preclearing institution with 33 cases and good practical feasibility was reported. Applying a simple to use screening instrument for refugee minors and their helpers, which is available in several languages creates the possibility of a shared definition of problems and solutions and is beneficial to helpers (e.g. volunteers, youth welfare services and medical doctors) as well as refugee minors.

Relationship between Massachusetts Youth Screening Instrument-second version and psychiatric disorders in youths in welfare and juvenile justice institutions in Switzerland.

BACKGROUND: There is growing evidence that it is important to have well-standardized procedures for identifying the mental health needs of youths in welfare and juvenile justice institutions. One of the most widely used tools for mental health screening in the juvenile justice system is the Massachusetts Youth Screening Instrument-second version (MAYSI-2). To contribute to the body of research examining the utility of the MAYSI-2 as a mental health screening tool; the first objective of the current study was to examine the relationship between the MAYSI-2 and the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime version (K-SADS-PL) in a sample of Swiss youths in welfare and juvenile justice institutions using a cross-sectional design. Secondly, as the sample was drawn from the French-, German- and Italian-speaking parts of Switzerland, the three languages were represented in the total sample and consequently differences between the language regions were analyzed as well. The third objective was to examine gender differences in this relationship. METHODS: Participants were 297 boys and 149 girls (mean age = 16.2, SD = 2.5) recruited from 64 youth welfare and juvenile justice institutions in Switzerland. The MAYSI-2 was used to screen for mental health or behavioral problems that could require further evaluation. Psychiatric classification was based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime version (K-SADS-PL). Binomial logistic regression analysis was used to predict (cluster of) psychiatric disorders from MAYSI-2 scales. RESULTS: The regression analyses revealed that the MAYSI-2 scales generally related well to their corresponding homotypic (cluster of) psychiatric disorders. For example, the alcohol/drug use scale identified the presence of any substance use disorder and the suicide ideation scale identified youths reporting suicide ideation or suicide attempts. Several MAYSI-2 scales were also related to heterotypic (cluster of) psychiatric disorders. For example, the MAYSI-2 scale alcohol/drug use, was positively related to any disruptive disorder. Furthermore, the results revealed gender differences in the relationship between the MAYSI-2 and K-SADS-PL (e.g., in the boys' subsample no MAYSI-2 scale was significantly related to any affective disorder; whereas, in the girls' subsample the MAYSI-2 scales depressed-anxious and somatic complaints were significantly related to any affective disorder). CONCLUSIONS: Overall, The MAYSI-2 seems to serve well as a first-stage screen to identify service needs for youths in welfare and juvenile justice institutions in Switzerland. Its effectiveness to identify the presence of (cluster of) psychiatric disorders differs between genders.

[Child sexual abuse. Epidemiology, clinical diagnostics, therapy, and prevention]. / Sexueller Missbrauch von Kindern und Jugendlichen. Aktuelle (fach-)politische Diskussion und Überblick über Definitionen, Epidemiologie, Diagnostik, Therapie und Prävention.

The article provides an overview of the research on sexual abuse and the current political developments in Germany. First, the terminology of sexual child abuse is discussed, followed by the presentation of epidemiological data. The section on diagnostics and therapy shows that--because of mostly nonspecific indicators--the diagnosis of child sexual abuse is very difficult to define. Child sexual abuse is discussed as a traumatic experience for children and adolescents with different psychiatric and physical diseases. Current studies have shown that especially cognitive behavioral therapeutic-oriented approaches are effective in curing posttraumatic stress disorders. Based on the new German Child Protection Act, the focus lies on the clarification of confidentiality for medical professionals and their right to consulting services for child protection. In conclusion, guidelines and minimum standards for a child prevention and protection model are presented as well as institutional recommendations addressed to all institutions (also clinical) that take care of or treat children and adolescents.

Therapeutic drug monitoring of children and adolescents treated with fluoxetine.

INTRODUCTION: Information about therapeutic serum levels of fluoxetine (FLX) and its major metabolite norfluoxetine (NORFLX) in children and adolescents is scarce. METHODS: Therapeutic drug monitoring (TDM) of FLX was routinely performed in 71 subjects treated for a major depressive disorder (MDD) (10-60 mg/d FLX, median: 20 mg/d). Correlations between serum concentration and dosage, age, gender, smoking habits and adverse events were analysed. RESULTS: Serum concentrations of the active moiety (FLX + NORFLX) ranged from 21 to 613 ng/mL (mean concentration of 213 ± 118 ng/mL, median: 185 ng/mL). High inter-individual variability in serum concentrations of the active moiety of FLX at each dosage level was observed and no relationship between serum concentration and clinical outcome was found. Apart from smoking, none of the factors tested had a significant eff ect on the serum concentration. DISCUSSION: It was shown that serum concentrations of the active moiety of FLX in children and adolescents seem to be similar to those in adults, with a high level of inter-individual variation. The proportion of patients who showed benefits from treatment with a dose of 20 mg/d FLX was high.

Stability of self-reported psychopathic traits in at-risk adolescents in youth welfare and juvenile justice institutions.

BACKGROUND: The purpose of this study was to evaluate the self-reported stability of psychopathic traits in adolescents in residential care (both child welfare and juvenile justice placed juveniles) and potential influencing factors. METHODS: We applied the Youth Psychopathic traits Inventory (YPI) in a sample of 162 adolescents (M = 15.0 years, SD = 1.3) over a mean time interval of 11 months (min. 6, max. 21 months, SD = 3.14). RESULTS: There was no significant difference in YPI total score nor in the three underlying dimensions Grandiose-Manipulative (GM), Callous-Unemotional (CU), and Impulsive-Irresponsible (II) between t1 and t2. Furthermore, approximately 70% of the adolescents showed no clinically significant reliable change on the YPI total score (as measured with the reliable change index), 15% improved, 15% deteriorated. The strongest predictor for psychopathic traits at t2 were psychopathic traits at t1. Additional predictors for higher levels of general psychopathic traits was male sex, for CU-traits male sex and lower levels of internalizing mental health problems, and for II-traits higher levels of externalizing mental health problems. Generally, the three reliable change groups (increase, no change, decrease) did not seemed to differ on relevant factors. CONCLUSIONS: Our results add to the findings that psychopathic traits are relatively stable in this at-risk group over approximately a 1-year time interval. Research with a longer follow-up time and more time points is warranted to better interpret these results.

[Adoption of OSCE Examination Procedures in Ophthalmology]. / Etablierung der OSCE-Prüfungsmethode in der Ophthalmologie.

BACKGROUND: The department of ophthalmology at the medical faculty of the University of Ulm provides additionally for interested students in clinical semesters an optional activity. In small groups the students deepen their theoretical knowledge and learn more about ophthalmological diagnostic standard procedures. The "objective structured clinical examination" (OSCE) is known as a useful tool in the assessment of clinical skills. The OSCE is a well-established and valid examination method, but also time-consuming and costly. In form of a trial the OSCE was launched during the optional activity "Look into my eyes, baby"; in the summer semester 2009. METHODS: By means of four examination areas established diagnostic methods in ophthalmology were tested. During the tests two simulation patients as well as two phantom heads for ophthalmological examinations were assessed. The preparation of the examination materials occurred in close collaboration with the department of ophthalmology and the division exam development of our university. In the assessment of the examinations a high value was set on good communication skills between students and simulation patients as well as on the professional handling of the student tasks. After the examinations the acceptance of the test methods was evaluated using a focused group interview between the students of the optional activity and the participating examiners. RESULTS: We performed two OSCEs involving three students each in the last two semesters. The OSCE was to a great extent time- and resource-consuming, due to the intensive pre- and post-reviewing and the time students needed to pass the various examination areas. Students and examiners as well confirmed the validity of the assessment and acknowledged a positive effect on the students learning behaviour. CONCLUSIONS: The teaching staff members are willing to accept the OSCE, especially when the assessment procedures are thoroughly planned and well structured. The acceptance of the students can be achieved by providing valid assessment and reviewed teaching conditions. The high input in personnel and instrumental resources for the assessment and the student's individual supervision should be critically discussed in the light of the efficacy of the additional ongoing hospital and outpatient services and the personnel-relevant education budget assigned to the department of ophthalmology of a university.

#patientstoo - Professional sexual misconduct by healthcare professionals towards patients: a representative study.

AIMS: Sexual border violations are a severe problem in the healthcare system. Studies using non-probability samples indicate a high prevalence of professional sexual misconduct (PSM) towards patients. However, valid prevalence rates are lacking. METHODS: We did a cross-sectional, observational study in Germany from February to April 2020. By different sampling steps, a probability sample of the German population above the age of 14 was generated. The final sample consisted 2503 persons (50.2% female, mean age: 49.5 years). Participants were asked about sexual contacts with and sexual harassment by healthcare professionals. Using descriptive statistics, prevalence rates of PSM were estimated. RESULTS: PSM was reported by 56 (4.5%) female and 17 (1.4%) male participants. In detail, 28 (2.2%) female and 10 (0.8%) male participants reported sexual contacts with healthcare professionals. One third of these sexual contacts took place before the age of 18 and one third against the will of the patients. 40 (3.2%) female and 8 (0.6%) male participants reported unnecessary physical examinations, 31 (2.5%) female and 7 (0.6%) male participants reported sexual harassment. The majority of perpetrators were male. CONCLUSIONS: Our data provide an important first insight into the prevalence of PSM by healthcare professionals towards patients in a representative sample. Results suggest a high prevalence of PSM in the general population of Germany. Preventive measures to increase awareness of PSM and concepts for protection of patients are needed.

The mediating role of COVID-19-related burden in the association between adverse childhood experiences and emotional exhaustion: results of the egePan - VOICE study.

Background: Adverse childhood experiences (ACEs) increase the risk for mental health problems. However, there is a lack of data targeting the role of ACEs for one of the most prevalent mental health problems in health-care professionals: burnout. Objective: We aimed to assess the relationship between ACEs and the core burnout dimension 'emotional exhaustion' (EE). As health-care professionals have been facing particular challenges during the COVID-19 pandemic, we furthermore aimed to assess the role of COVID-19 associated burden in the interplay between ACEs and EE. Methods: During the first lockdown in Germany, a total of 2500 medical healthcare professionals were questioned in a cross-sectional online survey. Questions targeted, among others, sociodemographics, ACEs, COVID-19-associated problems (e.g. increase of workload, worries about relatives and patients) and emotional exhaustion, measured by the respective dimension of the Maslach Burnout Inventory (MBI). Results: In German health-care professionals, ACEs were associated with a higher EE score. The number of experienced ACEs was associated with the majority of assessed COVID-19-associated problems. An increasing number of ACEs predicted higher EE scores, controlling for gender. The association between ACEs and EE was mediated significantly by COVID-19-associated problems. These included maladaptive coping strategies such as increased smoking, drinking and use of antidepressants/tranquilizers, feeling less protected by measures of the employee or the state, a greater feeling of being burdened by COVID-19-associated problems and greater exhaustion and sleep problems. Conclusion: Our findings suggest ACEs as significant risk factor for EE in German health-care professionals. The current pandemic means a significant burden that further pronounces this risk.

Antecedentes: Las experiencias adversas en la niñez (ACEs en sus siglas en inglés) aumentan el riesgo de problemas de salud mental. Sin embargo, faltan datos sobre el papel de las ACEs en uno de los problemas de salud mental más prevalentes en los profesionales de la salud: el agotamiento (burnout).Objetivo: Nuestro objetivo fue evaluar la relación entre las ACEs y la dimensión central del agotamiento 'agotamiento emocional' (AE). Dado que los profesionales de la salud se han enfrentado a desafíos particulares durante la pandemia de COVID-19, además nos propusimos evaluar el papel de la carga asociada a COVID-19 en la interacción entre las ACEs y la AE.Métodos: Durante la primera cuarentena en Alemania, se interrogó a un total de 2500 profesionales de la salud en una encuesta transversal en línea. Las preguntas fueron dirigidas, entre otros, a datos sociodemográficos, ACEs, problemas asociados a COVID-19 (por ejemplo, aumento de la carga de trabajo, preocupaciones sobre familiares y pacientes) y agotamiento emocional, medidos por la dimensión respectiva del Maslach Burnout Inventory (MBI).Resultados: En los profesionales sanitarios alemanes, las ACEs se asociaron con una puntuación de AE más alta. El número de ACEs experimentados se asoció con la mayoría de los problemas asociados a COVID-19 evaluados. Un mayor número de ACEs predijo puntuaciones de AE más altas, controlado por género. La asociación entre ACEs y AE fue mediada significativamente por problemas asociados con COVID-19. Estos incluyeron estrategias de afrontamiento desadaptativas, como fumar, beber y usar antidepresivos/tranquilizantes, sentirse menos protegido por las medidas del empleador o el estado, una mayor sensación de estar agobiado por los problemas asociados con COVID-19 y un mayor agotamiento y problemas de sueño.Conclusión: Nuestros hallazgos sugieren que las ACEs son un factor de riesgo significativo para la AE en los profesionales de la salud alemanes. La pandemia actual implica una carga importante que acentúa aún más este riesgo.

Serum concentrations, therapeutic response and side effects in children and adolescents with impulsive-aggressive symptoms during risperidone therapy.

INTRODUCTION: The aim of this prospective naturalistic study was to examine for the first time the relationship between dosage, serum concentration and clinical outcome in children and adolescents with impulsive-aggressive symptoms during risperidone therapy. METHODS: Steady state trough serum concentrations of risperidone and 9-hydroxyrisperidone (the active moiety) were measured in 103 subjects. The therapeutic effect was assessed by the clinical global impression improvement subscale and side effects by the Udvalg for Kliniske Undersogelser-side effect rating scale. RESULTS: We found a linear relationship between the risperidone dose and the serum concentration of the active moiety (Spearman rho=0.53) and no correlation between the serum concentration and either the therapeutic effect or side effects. There was no effect of gender and co-medication. DISCUSSION: This study has the typical limitations of naturalistic studies, therefore our results should be interpreted with caution. Based on the serum concentrations at the therapeutically effective dose range (0.25-1.5 mg/day) we obtained first information on a possibly appropriate therapeutic serum range for the risperidone treatment of children and adolescents with impulsive-aggressive symptoms. Further studies with greater sample sizes are needed to validate our results and to examine the influence of genetic polymorphisms on the serum concentration of risperidone.

[Social network analysis of interdisciplinary cooperation and networking in early prevention and intervention. A pilot study]. / Soziale Netzwerkanalyse interdisziplinärer Kooperation und Vernetzung in den Frühen Hilfen. Eine Pilotuntersuchung.

Child protection can only be successfully solved by interdisciplinary cooperation and networking. The individual, heterogeneous, and complex needs of families cannot be met sufficiently by one profession alone. To guarantee efficient interdisciplinary cooperation, there should not be any gaps in the network. In addition, each actor in the network should be placed at an optimal position regarding function, responsibilities, and skills. Actors that serve as allocators, such as pediatricians or youth welfare officers, should be in key player positions within the network. Furthermore, successful child protection is preventive and starts early. Social network analysis is an adequate technique to assess network structures and to plan interventions to improve networking. In addition, it is very useful to evaluate the effectiveness of interventions like round tables. We present data from our pilot project which was part of "Guter Start ins Kinderleben" ("a good start into a child's life"). Exemplary network data from one community show that networking is already quite effective with a satisfactory mean density throughout the network. There is potential for improvement in cooperation, especially at the interface between the child welfare and health systems.

Neural correlates of script-driven imagery in adolescents with interpersonal traumatic experiences: A pilot study.

In adults, trauma imagery has proven to be a useful tool to assess the neural mechanisms of psychological trauma processing. In adolescents, heterogeneous results could be found for other tasks, however, a trauma imagery paradigm has not been evaluated. For this purpose, we investigated a trauma imagery paradigm with control scripts to assess neural correlates of traumatic experiences in youth. 15 adolescents, who had experienced a traumatic interpersonal event in the past and have developed clinically relevant symptoms, underwent an fMRI scan while listening to their individual trauma- versus two control scripts (positive/negative). We analysed a parametric contrast of the imagery phases (trauma > negative > positive) which revealed activity in the thalamus, dorsal anterior cingulate cortex, cuneus, dorsomedial prefrontal cortex and amygdala. Additionally, amygdala-activity correlated positively with depression-symptom-severity. Our data provide evidence for the feasibility of fMRI during a trauma imagery task in adolescents to investigate networks previously related to hyperarousal in adults with PTSD. Further, we demonstrate the specificity of the activated networks for trauma imagery as compared to imagery of other emotional situations. The task might be particularly useful to evaluate neural correlates of treatment in adolescents when hyperarousal is a target symptom.

An international comparison of adolescent non-suicidal self-injury (NSSI) and suicide attempts: Germany and the USA.

BACKGROUND: This study examined the prevalence of non-suicidal self-injury (NSSI), suicide attempts, suicide threats and suicidal ideation in a German school sample and compared the rates with a similar sample of adolescents from the midwestern USA by using cross-nationally validated assessment tools. METHOD: Data were provided from 665 adolescents (mean age 14.8 years, S.D.=0.66, range 14-17 years) in a school setting. Students completed the Self-Harm Behavior Questionnaire (SHBQ), the Ottawa Self-Injury Inventory (OSI) and a German version of the Center for Epidemiological Studies-Depression Scale (CES-D). RESULTS: A quarter of the participants (25.6%) endorsed at least one act of NSSI in their life, and 9.5% of those students answered that they had hurt themselves repetitively (more than four times). Forty-three (6.5%) of the students reported a history of a suicide attempt. No statistically significant differences were observed between the German and US samples in terms of self-injury or suicidal behaviors. CONCLUSIONS: By using the same validated assessment tools, no differences were found in the prevalence and characteristics of self-injury and suicidal behaviors between adolescents from Germany and the USA. Thus, it seems that NSSI has to be understood as worldwide phenomenon, at least in Western cultures.

Limits of meta-analysis: methylphenidate in the treatment of adult attention-deficit hyperactivity disorder.

Guidelines for the treatment of attention-deficit hyperactivity disorder (ADHD) in adults advocate methylphenidate as first-line treatment. The aim of this study was to review the effectiveness of methylphenidate treatment of adult ADHD and to examine the influence of methods on meta-analytic results. Electronic databases were searched to identify clinical trials comparing methylphenidate with placebo in the treatment of adult ADHD. Studies were summarised with meta-analytic methods. Subgroup analyses were conducted with respect to parallel group versus cross-over trials and self versus observer ratings. The relationship between dosage and effect size was explored by weighted regression analysis. The results were tested for publication bias, and several sensitivity analyses were performed. Findings and methods were compared with a previous meta-analysis. Eighteen studies met the inclusion criteria of which 16 were included in the meta-analysis. The overall effect size (d = 0.42) was significantly different from zero, but was only half the size expected on the basis of a previous meta-analysis. No significant differences could be observed in the subgroup analyses. The regression analysis showed no significant influence of mean daily dose on effect size. These results contradict findings of a previous meta-analysis and challenge guideline recommendations. Methodological issues in meta-analyses are discussed.
