In two recent longitudinal studies the CBCL-DP in childhood was associated with heightened rates of comorbid psychiatric disorders, among them bipolar disorder, an increased risk for suicidality, and marked psychosocial impairment at young-adult follow-up. This is the first study outside the US that examines the longitudinal course of the CBCL-DP. Methods: We studied the diagnostic and functional trajectories and the predictive utility of the CBCL-DP in the Mannheim Study of Children at Risk, an epidemiological cohort study on the outcome of early risk factors from birth into adulthood. A total of 325 young adults (151 males, 174 females) participated in the 19-year assessment. Results: Young adults with a higher CBCL-DP score in childhood were at increased risk for substance use disorders, suicidality and poorer overall functioning at age 19, even after adjustment for parental education, family income, impairment and psychiatric disorders at baseline. Childhood dysregulation was not related to bipolar disorder in young adulthood. The CBCL-DP was neither a precursor of a specific pattern of comorbidity nor of comorbidity in general. Conclusions: Children with high CBCL-DP values are at risk for later severe, psychiatric symptomatology. The different developmental trajectories suggest that the CBCL-DP is not simply an early manifestation of a single disease process but might rather be an early developmental risk marker of a persisting deficit of self-regulation of affect and behavior.}, language = {en} } @article{BlomeyerBuchmannSchmidetal.2011, author = {Blomeyer, Dorothea and Buchmann, Arlette F. and Schmid, Brigitte and Jennen-Steinmetz, Christine and Schmidt, Martin H. and Banaschewski, Tobias and Laucht, Manfred}, title = {Age at first drink moderates the impact of current stressful life events on drinking behavior in young adults}, series = {Alcoholism : clinical and experimental research ; the official journal of the American Medical Society on Alcoholism and the Research Society on Alcoholism}, volume = {35}, journal = {Alcoholism : clinical and experimental research ; the official journal of the American Medical Society on Alcoholism and the Research Society on Alcoholism}, number = {6}, publisher = {Wiley-Blackwell}, address = {Malden}, issn = {0145-6008}, doi = {10.1111/j.1530-0277.2011.01447.x}, pages = {1142 -- 1148}, year = {2011}, abstract = {Background: Recent evidence from animal experiments and studies in humans suggests that early age at first drink (AFD) may lead to higher stress-induced drinking. The present study aimed to extend these findings by examining whether AFD interacted with stressful life events (SLE) and/or with daily hassles regarding the impact on drinking patterns among young adults. Method: In 306 participants of an epidemiological cohort study, AFD was assessed together with SLE during the past 3 years, daily hassles in the last month, and drinking behavior at age 22. As outcome variables, 2 variables were derived, reflecting different aspects of alcohol use: the amount of alcohol consumed in the last month and the drinking frequency, indicated by the number of drinking days in the last month. Results: Linear regression models revealed an interaction effect between the continuous measures of AFD and SLE on the amount of alcohol consumed. The earlier young adults had their first alcoholic drink and the higher the levels of SLE they were exposed to, the disproportionately more alcohol they consumed. Drinking frequency was not affected by an interaction of these variables, while daily hassles and their interaction with AFD were unrelated to drinking behavior. Conclusions: These findings highlight the importance of early age at drinking onset as a risk factor for later heavy drinking under high load of SLE. Prevention programs should aim to raise age at first contact with alcohol. Additionally, support in stressful life situations and the acquisition of effective coping strategies might prevent heavy drinking in those with earlier drinking onset.}, language = {en} } @article{WittBuchmannBlomeyeretal.2011, author = {Witt, Stephanie H. and Buchmann, Arlette F. and Blomeyer, Dorothea and Nieratschker, Vanessa and Treutlein, Jens and Esser, G{\"u}nter and Schmidt, Martin H. and Bidlingmaier, Martin and Wiedemann, Klaus and Rietschel, Marcella and Laucht, Manfred and Wuest, Stefan and Zimmermann, Ulrich S.}, title = {An interaction between a neuropeptide Y gene polymorphism and early adversity modulates endocrine stress responses}, series = {Psychoneuroendocrinology}, volume = {36}, journal = {Psychoneuroendocrinology}, number = {7}, publisher = {Elsevier}, address = {Oxford}, issn = {0306-4530}, doi = {10.1016/j.psyneuen.2010.12.015}, pages = {1010 -- 1020}, year = {2011}, abstract = {Interindividual variability in the regulation of the human stress system accounts for a part of the individual's liability to stress-related diseases.

Early childhood adversity is a well-studied environmental factor affecting an individual's stress response which has been shown to be modulated by gene environment interaction (GxE). Neuropeptide Y (NPY) plays a role in stress regulation and genetic variation in NPY may influence stress responses. In this study, we analyzed the association of a common variant in the NPY gene promoter, rs16147, with cortisol and ACTH responses to acute psychosocial stress in young adults from the Mannheim Study of Children at Risk (MARS), an ongoing epidemiological cohort study following the outcome of early adversity from birth into adulthood. We found evidence of a GxE interaction between rs16147 and early adversity significantly affecting HPA axis responses to acute psychosocial stress. These findings suggest that the neurobiological mechanisms linking early adverse experience and later neuroendocrine stress regulation are modulated by a gene variant whose functional relevance is documented by increasing convergent evidence from in vitro, animal and human studies.}, language = {en} } @inproceedings{LauchtBlomeyerElFaddaghetal.2011, author = {Laucht, Manfred and Blomeyer, Dorothea and El-Faddagh, Mahha and Esser, G{\"u}nter and Schmidt, Martin and Banaschewski, Tobias and Becker, Katja}, title = {Are regulatory problems in infancy precursors of ADHD in childhood? a moderating role for the dopamine D4 receptor gene}, series = {Infant mental health journal}, volume = {32}, booktitle = {Infant mental health journal}, number = {3}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0163-9641}, pages = {212 -- 212}, year = {2011}, language = {en} } @article{PitzerJennenSteinmetzEsseretal.2011, author = {Pitzer, Martina and Jennen-Steinmetz, Christine and Esser, G{\"u}nter and Schmidt, Martin H. and Laucht, Manfred}, title = {Prediction of preadolescent depressive symptoms from child temperament, maternal distress, and gender results of a prospective, longitudinal study}, series = {Journal of developmental and behavioral pediatrics}, volume = {32}, journal = {Journal of developmental and behavioral pediatrics}, number = {1}, publisher = {Lippincott Williams \& Wilkins}, address = {Philadelphia}, issn = {0196-206X}, doi = {10.1097/DBP.0b013e3181f4a474}, pages = {18 -- 26}, year = {2011}, abstract = {Objective: The delineation of developmental pathways to juvenile depressive symptoms is of major clinical interest because these are known to be predictive for adult mood disorders and for a range of other mental health problems. This study investigates the impact of child temperament and early maternal distress, both of which are known to influence children's emotional development, on preadolescent depression. Methods: In a prospective, longitudinal at-risk sample (163 boys, 178 girls), we assessed temperament at the age of 3 months and at 2 years, 4.5 years, and 8 years, respectively, and chronic maternal distress during infancy. Hierarchical linear regression analysis was used to investigate the prediction of depressive symptoms at the age of 11 years measured by the Child Depression Inventory. In addition, we controlled for psychosocial and obstetric perinatal risks and gender. Results: Psychosocial risks and self-control temperament made significant independent contributions to preadolescent depression, whereas fearful, difficult temperament and obstetric risks were unrelated to depressive outcome. Interestingly, a clear gender difference emerged with a significant prediction from maternal distress only in girls. Conclusions: Our data extend previous findings of a concurrent association between regulative temperament and juvenile depression to a predictive view. Furthermore, the results point toward gender-specific pathways to preadolescent depression and support earlier findings indicating that subclinical maternal distress may exert as detrimental effects on child development as clinical depression.}, language = {en} } @article{PitzerJennenSteinmetzEsseretal.2011, author = {Pitzer, Martina and Jennen-Steinmetz, Christine and Esser, G{\"u}nter and Schmidt, Martin H. and Laucht, Manfred}, title = {Differential susceptibility to environmental influences the role of early temperament and parenting in the development of externalizing problems}, series = {Comprehensive psychiatry : official journal of the American Psychopathological Association}, volume = {52}, journal = {Comprehensive psychiatry : official journal of the American Psychopathological Association}, number = {6}, publisher = {Elsevier}, address = {Philadelphia}, issn = {0010-440X}, doi = {10.1016/j.comppsych.2010.10.017}, pages = {650 -- 658}, year = {2011}, abstract = {Objective: A difficult or undercontrolled temperament, as well as harsh parental discipline or a lack of warmth, has long been regarded as risk factors for the development of externalizing problems. In addition, it has been suggested that children with difficult temperament are especially susceptible to rearing influences. We investigated the impact of early temperament and parenting and their interactions on externalizing behavior at school age. Methods: Participants were 148 boys and 160 girls from a prospective longitudinal study on a high-risk sample. At ages 3 months and 2 years, temperament was assessed by a highly structured parent interview and standardized behavioral observations. Maternal parenting was assessed by videotaped behavioral observation and a parent questionnaire. Externalizing problems at age 8 years were measured by the Child Behavior Checklist. Results: Using hierarchical linear regression analyses, we found that externalizing problems were predicted by psychosocial adversity and poor self-control, whereas no main effect for restrictive parenting or maternal empathy was found. Fearful-inhibited boys were positively affected by empathic and sensitive parenting, whereas girls who were low in self-control and/or fearful developed less externalizing problems with restrictive parenting. Conclusion: Our results partly support the differential susceptibility hypothesis.

In the present study, the long-term impact of maternal responsiveness and stimulation during early mother child interaction on depressive psychopathology was examined until adulthood. Data are from an epidemiological cohort study of the long-term outcome of early risk factors assessed at birth. At age 3 months, mothers and infants were videotaped during a nursing and playing situation. Maternal responsiveness and stimulation as well as infant responsiveness were evaluated by trained raters. At age 19 years, 314 participants (145 males, 169 females) were characterized on measures of depression through interview and questionnaire. In addition, measures of depression and anxiety were available from assessments in childhood. Results indicated that less maternal stimulation during early interaction was associated with a higher risk of depression in the offspring until the age of 19 years. In addition, children of less stimulating mothers showed more depressive symptoms at age 19 years and displayed more anxiety and depressive symptoms between the ages of 4.5 and 15 years. In contrast, maternal responsiveness was unrelated to children's outcome. In accordance with findings from animal research, the present study provides first longitudinal evidence in humans of a continuous and long-term influence of early maternal interaction behavior on the offspring's psychological adjustment until adulthood. The results suggest that the amount of maternally initiated contact behavior in a very early developmental stage may be crucial for children's mental health, regardless of child and maternal responsiveness.}, language = {en} } @article{HoltmannBuchmannEsseretal.2011, author = {Holtmann, Martin and Buchmann, Arlette F. and Esser, G{\"u}nter and Schmidt, Martin H. and Banaschewski, Tobias and Laucht, Manfred}, title = {The child behavior checklist-dysregulation profile predicts substance use, suicidality, and functional impairment a longitudinal analysis}, series = {The journal of child psychology and psychiatry}, volume = {52}, journal = {The journal of child psychology and psychiatry}, number = {2}, publisher = {Wiley-Blackwell}, address = {Malden}, issn = {0021-9630}, doi = {10.1111/j.1469-7610.2010.02309.x}, pages = {139 -- 147}, year = {2011}, abstract = {Background: Recent studies have identified a Child Behavior Checklist profile that characterizes children with severe affective and behavioral dysregulation (CBCL-dysregulation profile, CBCL-DP).

Primate and human studies have shown that early life stress increases the propensity for alcohol abuse in later life. The reinforcing properties of alcohol are mediated by dopaminergic signaling; however, there is little evidence to indicate how stress alters alcohol reinforcement. KCNJ6 (the gene encoding G-protein-coupled inwardly rectifying potassium channel 2 (GIRK2)) is a brain expressed potassium channel with inhibitory effects on dopaminergic tone. The properties of GIRK2 have been shown to be enhanced by the stress peptide corticotrophin-releasing hormone. Therefore, we sought to examine the role of KCNJ6 polymorphisms in adult alcohol dependence and stress-related alcohol abuse in adolescents. We selected 11 SNPs in the promoter region of KCNJ6, which were genotyped in 1152 adult alcohol dependents and 1203 controls. One SNP, rs2836016, was found to be associated with alcohol dependence (p = 0.01, false discovery rate). We then assessed rs2836016 in an adolescent sample of 261 subjects, which were characterized for early life stress and adolescent hazardous drinking, defined using the Alcohol Use Disorders Identification Test (AUDIT), to examine gene-environment interactions. In the adolescent sample, the risk genotype of rs2836016 was significantly associated with increased AUDIT scores, but only in those individuals exposed to high levels of psychosocial stress in early life (p = 0.01). Our findings show that KCNJ6 is associated with alcohol dependence and may moderate the effect of early psychosocial stress on risky alcohol drinking in adolescents. We have identified a candidate gene for future studies investigating a possible functional link between the response to stress and alcohol reinforcement.}, language = {en} }
