Preventive and therapeutic interventions for children of mentally ill parents Abstract. The risk of developing mental disorders increases markedly in children of mentally ill parents. Several risk factors have been identified and become possible targets of preventive and therapeutic interventions. Numerous studies investigated the efficacy of these interventions, which are very heterogeneous regarding content and methodology. One part of these studies focuses on infants of depressed and substance-addicted mothers; the other part focuses on children and adolescents of parents suffering from various mental disorders. Today, we have several meta-analyses at our disposal which yielded small effect sizes concerning the development of psychological symptoms or disorders in these affected children. The current review reveals a lack of high-quality studies, and analyses on cost-effectiveness are also needed. The preventive and therapeutic interventions now available show inadequate efficacy to effectively improve the situation of these children and adolescents. Future research is needed to develop and implement cost-effective interventions as well as high-quality studies to investigate the efficacy of these interventions.

Quality of life and psychological co-morbidities in children and adolescents with cardiac pacemakers and implanted defibrillators: a cohort study in Eastern Germany.

INTRODUCTION: The implantation of a pacemaker or an implantable cardioverter-defibrillator during childhood may reduce quality of life and lead to mental health problems. This study aimed to evaluate potential mental health problems (i.e., depressive and anxiety symptoms) and quality of life in children with cardiac active devices in comparison to healthy peers. METHODS: We analysed data of children with pacemakers or implantable cardioverter-defibrillators aged 6-18 years. Quality of life, depressive and anxiety symptoms were assessed by standardised questionnaires. The results were compared to age-matched reference groups. RESULTS: Children with implantable cardioverter-defibrillator showed significant lower quality of life in comparison to reference group (p = 0.03), but there was no difference in quality of life between children with pacemaker and reference group. There was no significant difference in depressive symptoms between children with a cardiac rhythm device compared to reference group (self-report: p = 0.67; proxy report: p = 0.49). There was no significant difference in anxiety (p = 0.53) and depressive symptoms (p = 0.86) between children with pacemaker and children with implantable cardioverter-defibrillator. CONCLUSIONS: Living with an implantable cardioverter-defibrillator in childhood seems to decrease the patients' quality of life. Although children with pacemaker and implantable cardioverter-defibrillator don't seem to show more depressive and anxiety symptoms in comparison to their healthy peers, there still can be an increased risk for those children to develop mental health problems. Therefore, treating physicians should be aware of potential mental health problems and provide the patients and their families with appropriate therapeutic offers.

[LIFE Child Depression - a prospective longitudinal cohort study on the origin of depressive disorders between childhood and early adulthood]. / LIFE Child Psychische Entwicklung/Depression ­ Prospektive longitudinale Kohortenstudie zur Erfassung von Entstehungsbedingungen depressiver Störungen von der Kindheit bis ins junge Erwachsenenalter.

LIFE Child Depression - a prospective longitudinal cohort study on the origin of depressive disorders between childhood and early adulthood LIFE Child Depression is a prospective longitudinal study on the origin and course of depressive symptoms and disorders between child- and adulthood. The aim of the study is to identify patterns of developmental courses of symptoms and disorders and to investigate the interplay of psychosocial, biological and genetic risk and protective factors in the development of depressive disorders. The present paper gives an overview on results of the study. The sample was already assessed three times. A clinical sample was recruited from two local child psychiatric in- and outpatient services in Leipzig, a control sample was recruited from a children's health check program at our medical faculty (LIFE Child Health) and from the local registration office. We found some important context- and parent-associated risk factors for depressive disorders, such as negative life events, low socioeconomic status and depression in mothers (but not in fathers). Moreover, we found some characteristic biological and cognitive-emotional characteristics of children with depressive disorders, such as low stress-related cortisol, low evaluation of own performance, and more negative cognitions in dealing with stressful situations, low self-esteem and a general impairment of emotional processing of human faces. Only some of the risk factors were found to be specific to depression. Instead, most of them can be regarded as general risk factors for psychological disorders in childhood. It is also noteworthy, that some of the risk associations were gender-specific and need to be looked at from a differential point of view. Our study gives important indications for prevention for children at risk for depressive disorders as well as for therapeutic approaches.

[Various socioeconomic factors as predictors of internalizing and externalizing disorders in children and adolescents]. / Verschiedene sozioökonomische Faktoren als Prädiktoren für internalisierende und externalisierende Störungsbilder des Kindes- und Jugendalters.

Various socioeconomic factors as predictors of internalizing and externalizing disorders in children and adolescents Abstract. Objective: Socioeconomic status (SES) is an important risk factor for psychiatric disorders in children and adolescents. Various SES parameters are included in research efforts. This paper investigates the predictive value of different individual SES measures and the combination thereof regarding internalizing and externalizing disorders in children and adolescents. Method: We used data from N = 381 8- to 14-year-olds who had been recruited in child and adolescent psychiatric facilities and in the general population. Based on a diagnostic parent interview (K-SADS-PL), we divided the sample into internalizing and externalizing groups and a healthy control group. The SES data of both parents were collected. Education, occupational status, and income were integrated as single factors as well as combined factor to form the SES index. Additionally, we assessed unemployment. Results: Using multivariate analyses, we controlled for age and sex. All single factors turned out to be significant risk factors for internalizing and externalizing disorders. Occupational status was the most important single factor. The explained variance for the SES index was as high as for occupational status. Unemployment was not predictive when examined simultaneously with the SES index. Conclusion: Future studies should integrate the SES as risk factor and use the SES index or occupational status as single factor. The integration of unemployment is not necessarily needed.

Endocrinological and subjective stress responses in children with depressive, anxiety, or externalizing disorders.

In this study, we used a stress test to investigate endocrinological and subjective stress responses of 8- to 14-year-old children with internalizing or externalizing disorders and healthy controls. The sample (N = 170) consisted of clinical and community children. Parents were given a diagnostic interview to diagnose their children's psychiatric condition. We measured saliva cortisol and subjectively experienced arousal in children before and after the Trier Social Stress Test for Children. Children also rated their performance immediately after the stress test, and 1 hr later they rated their positive and negative thoughts about this stressful event. Children with internalizing or externalizing disorders exhibited a blunted cortisol response compared to healthy controls. Depressed children rated their test performance lower and reported more negative thoughts after the test in comparison to healthy controls, anxious children reported more arousal before and after the task, and children with externalizing disorders reported more positive thoughts. In regression analyses, cortisol and subjective stress responses were both predictive of psychiatric disorders. The study extends previous work on the relation between psychiatric disorders and children's stress responses to an experimentally induced stress task by including a broad range of psychiatric disorders and by integrating endocrinological and subjective stress responses.

Self-Esteem of 8-14-Year-Old Children with Psychiatric Disorders: Disorder- and Gender-Specific Effects.

In this study, we investigated the relation between global and domain-specific self-esteem and psychiatric disorders. A sample of 577 children aged 8-14 years was recruited via psychiatric hospitals and from the general population. Parents were given a diagnostic interview to assess children's psychiatric diagnoses (current/past). Parents and children completed questionnaires on child symptoms. Children completed a questionnaire on global and domain-specific self-esteem (scales: scholastic competence, social acceptance, athletic performance and physical appearance, global self-esteem). Self-esteem of children with current psychiatric disorders was lower than that of healthy controls (η p2 between 0.01 and 0.08). Concerning scholastic competence, social acceptance and global self-esteem, children with past psychiatric disorders scored also lower than healthy controls. Different current psychiatric disorders showed specific but small effects on dimensions of self-esteem (ß between -0.08 and 0.19). Moreover, we found a gender × group interaction, indicating that girls with depressive and adjustment disorders were specifically impaired in their global self-esteem and perception of their physical appearance. Findings might help clinicians to focus on particular domains of self-esteem during the diagnostic process and to define adequate treatment goals.

Immunoassay or LC-MS/MS for the measurement of salivary cortisol in children?

BACKGROUND: Dysregulation of the adrenal cortex has been assessed with measurement of salivary cortisol. So far salivary cortisol is routinely measured with immunoassay (IA). However, liquid chromatography-tandem mass spectrometry (MS) is known to offer better specificity. We compared the concentrations of salivary cortisol measured by MS and IA at basal and stress induced conditions and evaluated reasons for the difference in method-dependent cortisol results. METHODS: Saliva samples (n=2703) were collected from 169 children (age range: 8-14 years; 81 healthy children; 55 with internalizing and 33 with externalizing disorders) under circadian conditions and during the Trier Social Stress Test for Children (TSST-C). Biochemical analyses were performed with MS for cortisol and cortisone, IA (IBL, RE62011) for cortisol, and enzyme kinetic assay for α-amylase. RESULTS: MS and IA showed mostly comparable results for circadian activity and TSST-C response with similar statistical power. However, IA measured cortisol concentrations about 2.39-fold higher than MS. We found that this difference in measured values between MS and IA was mainly due to different standardization of IA compared to MS. In addition, at cortisol IA concentration below 5 nmol/L, cross-reactivity with cortisone was found to contribute to the lower concordance between MS and IA. CONCLUSIONS: Immunoassay and LC-MS/MS were largely comparable in the interpretation of salivary cortisol dynamics in stress research. But the IA method revealed a restricted accuracy in the measuring range below 5 nmol/L.

Early processing of emotional faces in a Go/NoGo task: lack of N170 right-hemispheric specialisation in children with major depression.

Emotionally biased information processing towards sad and away from happy information characterises individuals with major depression. To learn more about the nature of these dysfunctional modulations, developmental and neural aspects of emotional face processing have to be considered. By combining measures of performance (attention control, inhibition) in an emotional Go/NoGo task with an event-related potential (ERP) of early face processing (N170), we obtained a multifaceted picture of emotional face processing in a sample of children and adolescents (11-14 years) with major depression (MDD, n = 26) and healthy controls (CTRL, n = 26). Subjects had to respond to emotional faces (fearful, happy or sad) and withhold their response to calm faces or vice versa. Children of the MDD group displayed shorter N170 latencies than children of the CTRL group. Typical right lateralisation of the N170 was observed for all faces in the CTRL but not for happy and calm faces in the MDD group. However, the MDD group did not differ in their behavioural reaction to emotional faces, and effects of interference by emotional information on the reaction to calm faces in this group were notably mild. Although we could not find a typical pattern of emotional bias, the results suggest that alterations in face processing of children with major depression can be seen at early stages of face perception indexed by the N170. The findings call for longitudinal examinations considering effects of development in children with major depression as well as associations to later stages of processing.

From Maltreatment to Psychiatric Disorders in Childhood and Adolescence: The Relevance of Emotional Maltreatment.

Different forms of maltreatment are thought to incur a cumulative and non-specific toll on mental health. However, few large-scale studies draw on psychiatric diagnoses manifesting in early childhood and adolescence to identify sequelae of differential maltreatment exposures, and emotional maltreatment, in particular. Fine-grained multi-source dimensional maltreatment assessments and validated age-appropriate clinical interviews were conducted in a sample of N = 778 3 to 16-year-olds. We aimed to (a) substantiate known patterns of clinical outcomes following maltreatment and (b) analyse relative effects of emotional maltreatment, abuse (physical and sexual), and neglect (physical, supervisory, and moral-legal/educational) using structural equation modeling. Besides confirming known relationships between maltreatment exposures and psychiatric disorders, emotional maltreatment exerted particularly strong effects on internalizing disorders in older youth and externalizing disorders in younger children, accounting for variance over and above abuse and neglect exposures. Our data highlight the toxicity of pathogenic relational experiences from early childhood onwards, urging researchers and practitioners alike to prioritize future work on emotional maltreatment.

Diagnostic value of resting electroencephalogram in attention-deficit/hyperactivity disorder across the lifespan.

The resting electroencephalogram (EEG) reflects development and arousal, but whether it can support clinical diagnosis of attention-deficit/hyperactivity disorder (ADHD) remains controversial. Here we examined whether theta power and theta/beta ratio are consistently elevated in ADHD and younger age as proposed. Topographic 48-channel EEG from 32 children (8-16 years) and 22 adults (32-55 years) with ADHD and matched healthy controls (n = 30 children/21 adults) was compared. Following advanced artefact correction, resting EEG was tested for increased theta and theta/beta activity due to ADHD and due to normal immaturity. Discriminant analyses tested classification performance by ADHD and age using these EEG markers as well as EEG artefacts and deviant attentional event-related potentials (ERPs). No consistent theta or theta/beta increases were found with ADHD. Even multivariate analyses indicated only marginal EEG power increases in children with ADHD. Instead, consistent developmental theta decreases were observed, indicating that maturational lags of fewer than 3 years would have been detected in children. Discriminant analysis based on proposed simple spectral resting EEG markers was successful for age but not for ADHD (81 vs. 53 % accuracy). Including ERP markers and EEG artefacts improved discrimination, although not to diagnostically useful levels. The lack of consistent spectral resting EEG abnormalities in ADHD despite consistent developmental effects casts doubt upon conventional neurometric approaches towards EEG-based ADHD diagnosis, but is consistent with evidence that ADHD is a heterogeneous disorder, where the resting state is not consistently characterised by maturational lag.

The LIFE child study: a life course approach to disease and health.

BACKGROUND: Profound knowledge about child growth, development, health, and disease in contemporary children and adolescents is still rare. Epidemiological studies together with new powerful research technologies present exciting opportunities to the elucidation of risk factor-outcome associations with potentially major consequences for prevention, diagnosis and treatment. AIM: To conduct a unique prospective longitudinal cohort study in order to assess how environmental, metabolic and genetic factors affect growth, development and health from fetal life to adulthood. METHODS: The 'Leipzig Research Centre for Civilization Diseases (LIFE) Child Study' focuses on two main research objectives: (1) monitoring of normal growth, development and health; (2) non-communicable diseases such as childhood obesity and its co-morbidities, atopy and mental health problems. Detailed assessments will be conducted alongside long-term storage of biological samples in 2,000 pregnant women and more than 10,000 children and their families. RESULTS: Close coordination and engagement of a multidisciplinary team in the LIFE Child study successfully established procedures and systems for balancing many competing study and ethical needs. Full participant recruitment and complete data collection started in July 2011. Early data indicate a high acceptance rate of the study program, successful recruitment strategies and the establishment of a representative cohort for the population of Leipzig. A series of subprojects are ongoing, and analyses and publications are on their way. DISCUSSION: This paper addresses key elements in the design and implementation of the new prospective longitudinal cohort study LIFE Child. Given the recognized need for long-term data on adverse effects on health and protective factors, our study data collection should provide magnificent opportunities to examine complex interactions that govern the emergence of non-communicable diseases.

Attenuated LPP to Emotional Face Stimuli Associated with Parent- and Self-Reported Depression in Children and Adolescents.

Individuals diagnosed with a depressive disorder have been found to show reduced reactions to emotional information consistent with the hypothesis of an emotional context insensitivity. However, there are contradictory findings of enhanced reactivity and mood-congruent processing. Electroencephalography (EEG) recordings of the late positive potential (LPP) can display such blunted or enhanced activity. Due to these contradictory findings, there is a need to clarify the role of the LPP in the emergence and presence of depressive disorders especially in children. We used an emotional Go/NoGo task to investigate modulations of the LPP to emotional (fearful, happy, sad) and calm faces in a sample of children and adolescents (age 11;00-14;11) diagnosed with a depressive disorder according to diagnostic parent interviews (K-SADS-PL) (n = 26) compared to a group of age-matched healthy controls (n = 26). LPP positivity was attenuated in children and adolescents with a depressive disorder as well as with higher self-reported depressive symptoms, suggesting reduced reactivity to emotional and calm faces. This is the first study to find generally blunted LPP responses in a clinical sample of depressed youth across reporters. Such dysfunctional modulation of neural activity may represent a potential biomarker for depressive disorders. The results call for further prospective studies investigating the course of the LPP before and after the onset of a depressive disorder in youth.

Implementing the K-SADS-PL as a standard diagnostic tool: Effects on clinical diagnoses.

Diagnostic interviews are valuable tools for generating reliable and valid psychiatric diagnoses. However, little is known about the diagnostic effects of implementing such an interview into the standard diagnostic procedure of a child psychiatric clinic. Therefore, we reviewed discharge diagnoses of psychiatric patients (age: 8-12 years; combined sample of inpatients and day hospital patients) over two intervals before and after implementing the semi-structured diagnostic interview K-SADS-PL as a diagnostic tool during intake. Each interval was a two year period spanning from 2009-2010 (pre sample; n=177) and from 2012-2013 (post sample; n=132). The number of diagnoses per patient and the co-morbidity rate increased significantly in the post sample. Furthermore, the percentage of children with a nonspecific diagnosis "other mixed disorders of conduct and emotions" (ICD-10: F92.8) decreased significantly after using the K-SADS-PL. Regarding the main diagnostic categories, a significant increase in the number of anxiety disorders and stress-related and somatoform disorders was found in the post sample. The results suggest that implementing a semi-structured interview into the daily routine of child psychiatry may have a substantial impact on discharge diagnoses. Practical implications are discussed and ideas for future research are given.

Feeding, eating and behavioral disturbances in Prader-Willi syndrome and non-syndromal obesity.

BACKGROUND: Although most individuals with Prader-Willi syndrome (PWS) are obese, little is known about the impact of obesity-related psychosocial factors in PWS. In the present study we compared feeding, eating, and behavioral disturbances in children and adolescents with PWS, peers with non-syndromal obesity, and normal weight controls. METHODS: Twelve persons with PWS, aged 7-22 years, age- and gender-matched obese and normal weight individuals were analyzed regarding parental feeding practices, eating disturbances, and behavioral problems via standardized questionnaires. RESULTS: Parents of individuals with PWS reported significantly more restrictive feeding and monitoring than did parents of obese or normal weight children without PWS (p<0.05). Social problems were more common in the obese and the PWS group than in the normal-weight group (p<0.05). Behavioral problems were significantly correlated with parental restrictive feeding practices. CONCLUSIONS: Our data show that children and adolescents with PWS are affected by psychosocial problems, and that restrictive feeding practices might be associated with more severe behavioral problems. Further studies in larger samples will be necessary to replicate these results and possibly provide new therapeutic approaches for the management of PWS.

Mental Disorders in Early Childhood.

BACKGROUND: About 17% of all children suffer from a mental disorder in early childhood, defined as the period up to the age of 6 years. METHODS: This review is based on publications retrieved by a selective search in PubMed and the Web of Science, as well as on the authors' clinical and scientific experience. RESULTS: In children up to age 2, disorders of emotional and motor regulation are common (ca. 7%), as are feeding problems (25%), which persist in 2% of children to meet the diagnostic criteria for a feeding disorder. Reactive attachment disorder, a serious mental illness, has a prevalence of about 1%: it is more common among children in situations of increased risk, e.g., orphanages and foster homes. Preschool children can develop anxiety disorder and depressive disorder, as well as hyperactivity and behavioral disorders (the latter two mainly in boys). Parent training and parent-child psychotherapy have been found to be effective treatments. There is no evidence that psychotropic drugs are effective in early childhood. CONCLUSION: The diagnostician should act cautiously when assigning psychopathological significance to symptoms arising in early childhood but should still be able to recognize mental disorders early from the way they are embedded in the child's interactive relationships with parents or significant others, and then to initiate the appropriate treatment. Psychotherapy in this age group is still in need of validation by efficacy studies and longitudinal studies of adequate quality.

The acceptance of the K-SADS-PL - potential predictors for the overall satisfaction of parents and interviewers.

The presented study investigated the interviewee (parents) and interviewer acceptance of the semi-structured diagnostic interview Kiddie Schedule for Affective Disorders and Schizophrenia for School Aged Children Present Lifetime version (KSADS-PL; German version). Seventeen certified interviewers conducted 231 interviews (interviewers conducted several interviews; interviewees were only questioned once). Interviewees and interviewers anonymously rated their acceptance right after the interview was finished. The nested data structure was analysed regarding an individual interviewer bias and potential predictors of overall satisfaction. Therefore, factors improvable by interviewer training were included, as well as fixed factors which cannot be improved by professional training. The overall satisfaction was evaluated as highly positive with significant higher interviewee and interviewer ratings in the research as compared to the clinical recruitment setting. An individual bias of the interviewer on his or her own acceptance over time, but not on the evaluation of the corresponding interviewee was found. Neither the professional background nor the gender of the interviewer had a significant contribution in predicting these differences. The interviewer model showed no significant change over time and only the interview duration and the interviewee acceptance were significant predictors for interviewer overall satisfaction. Regarding the interviewee model, just the interviewer acceptance was a significant predictor. Copyright Copyright © 2015 John Wiley & Sons, Ltd.

The hyporeactivity of salivary cortisol at stress test (TSST-C) in children with internalizing or externalizing disorders is contrastively associated with α-amylase.

BACKGROUND: Stress biomarkers of the autonomic nervous system and hypothalamic-pituitary-adrenal axis (HPA-axis) can be measured via alpha-amylase (AA) and cortisol and cortisone in saliva. Objectives were to determine 1) the response patterns of cortisol, cortisone, and AA under both circadian conditions and the Trier Social Stress Test for Children (TSST-C), 2) which reactivity index is most suitable to differentiate internalizing or externalizing disorders from controls, and to explore 3) the interaction between AA and cortisol in the presence of internalizing or externalizing disorders. METHODS: Saliva samples (n = 2893) from children with internalizing (n = 55) or externalizing disorders (n = 33) and healthy children (n = 81) were analyzed for cortisol, cortisone, and AA under circadian conditions and TSST-C. RESULTS: Circadian rhythm of three biomarkers did not differ between diagnostic groups. Age and gender were significant predictors for cortisol and awakening time influenced all three biomarkers significantly. TSST-C responses appeared sequentially in the order of AA, cortisol, and cortisone. Trajectories of cortisol and cortisone responses, not in AA, were significantly lower in children with internalizing or externalizing disorders than in healthy children. Cortisol percentage increase appeared to be the most suitable reactivity index to detect the difference between the diagnostic groups. Internalizing disorders had a negative association between AA decrease and cortisol increase (ß = -.199, p < .05, R(2) = .304). Externalizing disorders had a positive association between AA baseline and cortisol increase (ß = .229, p < .05, R(2) = .304). CONCLUSION: An altered HPA-axis response during stress might result from chronic allostatic load in internalizing disorders and underaroused stress response system in externalizing disorders.
