Entwicklung und Persistenz von Hell- und Dunkelfelddelinquenz im Jugend- und frühen Erwachsenenalter
(2002)
Ziel der Untersuchung war die Bedeutung der Dunkelfelddelinquenz für die Prognose der Delinquenzentwicklung und die Bedeutung psychiatrischer Auffälligkeiten für Entstehen und Verlauf psychischer Störungen zu klären. Die Stichprobe bestand aus 281 25-Jährigen, die im Alter von 8, 13 und 18 Jahren psychiatrisch untersucht, und die mit 18 und 25 Jahren bezüglich ihrer Dunkelfelddelinquenz befragt worden waren. Es ergab sich ein klarer Zusammenhang erhöhter Dunkelfelddelinquenzraten mit gerichtlich bestrafter Delinquenz im Jugendalter. Bei Einbeziehung der Dunkelfelddelinquenz in die Prognose mußte die Wahrscheinlichkeit für den Ausblick auf delinquenten Karrieren von 76 % auf 44 % nach unten korrigiert werden, entsprechend stieg der Anteil von erwachsener als auch fortgesetzter Delinquenz. Die Mehrheit der später gerichtlich bestraften Jugendlichen und jungen Erwachsenen war im Alter von 8 und 13 Jahren psychiatrisch unauffällig gewesen. Als überlegene Prädiktoren stellten sich umschriebene Entwicklungsstörungen und widrige familiäre Bedingungen im Grund- und Hauptschulalter heraus. Als Konsequenz muß die Dunkelfelddelinquenz bei der Verlaufsprognose delinquenten Verhaltens im Jugendalter berücksichtigt werden. Präventive Überlegungen müssen sich auf Kinder mit umschriebenen Entwicklungsstörungen und solche, die in widrigen familiären Verhältnissen leben, mehr konzentrieren als auf Kinder mit hyperkinetischen und dissozialen Störungen. Schlüsselwörter: Delinquenz, Dunkelfelddelinquenz, Entwicklung und Verlauf
Es werden Befunde aus einer prospektiven Laengsschnittstudie praesentiert, in der 321 Probanden im Alter von 8, 13, 18 und 25 Jahren untersucht werden konnten; ihre Dunkelfelddelinquenz wurde mit 18 und 25 Jahren erfasst. Wir suchten nach Assoziationen zur Delinquenzentwicklung und erwarteten Unterschiede zwischen auf das Jugendalter beschraenkter gegenueber ins fruehe Erwachsenenalter fortgesetzter sowie spaet, d.h. nach dem Alter von 18 Jahren, beginnender Delinquenz. Wir fanden gemeinsame Risikofaktoren und fuer die drei Verlaufstypen spezifische Risikokonstellationen, die eher im Jugendalter als in der Kindheit identifiziert wurden. Widrige familiaere Bedingungen, Entwicklungsverzoegerungen und psychische Stoerungen scheinen mit Delinquenz als eher persistentem Verhalten assoziiert.
Aims: To investigate whether concurrent alcohol and tobacco use during early adolescence characterizes a subgroup that differs from users of one substance only regarding several risk factors for later substance use problems. Methods: Participants were from a prospective longitudinal cohort study of 384 children at risk for later psychopathology, with the majority being born with obstetric complications and psychosocial adversities. Assessments of adolescent drug consumption and related intrapersonal characteristics were obtained at age 15. Results: Compared to consumers of alcohol only, 15-year-olds drinking and smoking during the same time period (past 4 weeks) had significantly higher levels of consumption and more excessive use of alcohol, started drinking at an earlier age, had higher scores on the Fagerstrom Test for Nicotine Dependence, and more cannabis use. This group could be distinguished from users of alcohol only by higher novelty seeking and more positive alcohol effect expectancies. Compared to consumers of tobacco only, concurrent users reported higher nicotine dependence and more cannabis use. No significant differences were observed regarding frequency and age at initiation of tobacco use, tobacco-related sensitivity, self- efficacy and instrumentality as well as novelty seeking. Conclusions: Concurrent alcohol and tobacco use during early adolescence is associated with characteristics that are well known as risk factors for later alcohol use problems and dependence and that should be targeted by prevention programs.
Maternal stimulation in infancy predicts hypothalamic-pituitary-adrenal axis reactivity in young men
(2013)
Evidence from animal research has demonstrated the effect of early maternal care on the offspring's endocrine and behavioral stress response in adulthood. The present prospective study investigates, in humans, the long-term impact of maternal responsiveness and stimulation during early mother-child interaction on adrenocorticotropic hormone (ACTH) and cortisol response to a psychosocial laboratory stressor in adulthood. The 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 10-min standardized nursing and playing situation and evaluated by trained raters for maternal stimulation and infant and maternal responsiveness. At age 19 years, 270 participants (146 females, 124 males) completed the Trier Social Stress Test. The results indicated that less maternal stimulation during early interaction at age 3 months predicted diminished plasma ACTH and cortisol increase in response to acute psychosocial stress in male, but not female offspring. In contrast, maternal responsiveness was found to be unrelated to hypothalamic-pituitary-adrenal (HPA) reactivity. In accordance with the findings from animal research, the present study provides prospective evidence in humans of a long-term association between early maternal interaction behavior and the offspring's hormonal stress response in young adulthood, suggesting that poor maternal stimulation in early infancy may result in reduced HPA axis reactivity to an acute psychosocial stressor in males.
Evidence from animal research has revealed that less maternal care results in disturbed emotionality in the offspring. 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.
Recent evidence suggests that heterogeneity in the age at onset could explain the inconsistent findings of association studies relating the dopamine transporter (DAT1) gene with alcohol and nicotine consumption. The aim of this study was to examine interactions between two DAT1 polymorphisms and different initiation ages with regard to alcohol and tobacco consumption levels and dependence. Two hundred and ninety-one young adults (135 males, 156 females) participating in the Mannheim Study of Children at Risk were genotyped for the 40-bp variable number of tandem repeats (VNTR) and rs27072 polymorphisms of DAT1. Age at initiation was assessed at age 15 and 19 years. Information about current alcohol and tobacco consumption was obtained at age 19 years using self-report measures and structured interviews. Results suggest that age at onset of intensive consumption moderated the association of the DAT1 gene with early adult substance use and dependence, revealing a DAT1 effect only among individuals homozygous for the 10r allele of the 40-bp VNTR who had started daily smoking or being intoxicated early in life. Equally, carriers of the T allele of the rs27072 polymorphism reporting an early age at first intoxication showed higher current alcohol consumption at age 19 years. In contrast, no interaction between rs27072 and the age at first cigarette with regard to later smoking was observed. These findings provide evidence that the DAT1 gene interacts with an early heavy or regular drug exposure of the maturing adolescent brain to predict substance (ab)use in young adulthood. Further studies are required to confirm these findings.
Calcularis is a computer-based training program which focuses on basic numerical skills, spatial representation of numbers and arithmetic operations. The program includes a user model allowing flexible adaptation to the child's individual knowledge and learning profile. The study design to evaluate the training comprises three conditions (Calcularis group, waiting control group, spelling training group). One hundred and thirty-eight children from second to fifth grade participated in the study. Training duration comprised a minimum of 24 training sessions of 20 min within a time period of 6–8 weeks. Compared to the group without training (waiting control group) and the group with an alternative training (spelling training group), the children of the Calcularis group demonstrated a higher benefit in subtraction and number line estimation with medium to large effect sizes. Therefore, Calcularis can be used effectively to support children in arithmetic performance and spatial number representation.
Recent longitudinal studies have indicated that affective and behavioral dysregulation in childhood is associated with an increased risk for various negative outcomes in later life. However, few studies to date have examined early mechanisms preceding dysregulation during early childhood. Aim of this study was to elucidate early mechanisms relating to dysregulation in later life using data from an epidemiological cohort study on the long-term outcome of early risk factors from birth to adulthood. At age 3 months, mothers and infants were videotaped during a nursing and playing situation. Maternal responsiveness was evaluated by trained raters. Infant regulatory problems were assessed on the basis of a parent interview and direct observation by trained raters. At age 8 and 11 years, 290 children (139 males) were rated on the Child Behavior Checklist (CBCL). Additionally, participants were genotyped for the dopamine D4 receptor (DRD4) exon 3 VNTR polymorphism. A significant three-way interaction between maternal responsiveness, DRD4 genotype and infant regulatory problems was detected predicting the CBCL-dysregulation profile (CBCL-DP). Carriers of the DRD4 7r allele with regulatory problems at age 3 months showed significantly more behavior problems associated with the CBCL-DP during childhood when exposed to less maternal responsiveness. In contrast, no effect of maternal responsiveness was observed in DRD4 7r carriers without infant regulatory problems and in non-carriers of the DRD4 7r allele. This prospective longitudinal study extends earlier findings regarding the association of the CBCL-DP with early parenting and later psychopathology, introducing both DRD4 genotype and infant regulatory problems as important moderators.

Background:
Children’s spontaneous focusing on numerosity (SFON) is related to numerical skills. This study aimed to examine (1) the developmental trajectory of SFON and (2) the interrelations between SFON and early numerical skills at pre-school as well as their influence on arithmetical skills at school.
Method:
Overall, 1868 German pre-school children were repeatedly assessed until second grade. Nonverbal intelligence, visual attention, visuospatial working memory, SFON and numerical skills were assessed at age five (M = 63 months, Time 1) and age six (M = 72 months, Time 2), and arithmetic was assessed at second grade (M = 95 months, Time 3).
Results:
SFON increased significantly during pre-school. Path analyses revealed interrelations between SFON and several numerical skills, except number knowledge. Magnitude estimation and basic calculation skills (Time 1 and Time 2), and to a small degree number knowledge (Time 2), contributed directly to arithmetic in second grade. The connection between SFON and arithmetic was fully mediated by magnitude estimation and calculation skills at pre-school.
Conclusion:
Our results indicate that SFON first and foremost influences deeper understanding of numerical concepts at pre-school and—in contrast to previous findings –affects only indirectly children’s arithmetical development at school.
The psycho-social development of both preterm and term children (n=347) whose mothers reported tocolytic treatment was assessed at the ages of 2, 4.5, 8 years. Term children exposed to tocolysis showed a higher rate of psychiatric disorders as well as poorer cognitive and motor performance than controls. In the preterm children no adverse impact of tocolysis could be found. The results are discussed concerning possible ways in which tocolytic treatment may influence child development. Restrictions because of the preliminary character of this study and the need of further prospective studies to clarify the developmental impact of tocolysis are also considered.
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.
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 addition, they point toward gender-specific pathways in the development of externalizing problems.
Objective: Despite theoretical discrepancies between different concepts of temperament, some core dimensions are thought to be common to the various models. We compared temperamental traits derived from the New York Longitudinal Study (NYLS) model and the Cloninger dimensions in the developmental course and investigated the associations of temperament with sex as well as with obstetric risks or psychosocial risks present at birth. - Methods: Participants were 151 boys and 157 girls born at differing degrees of obstetric and psychosocial risk from a longitudinal study on a high-risk community sample. In infancy and childhood, NYLS-derived temperamental characteristics were assessed by a highly structured parent interview and standardized behavioral observations. At age 15 years, the Junior Temperament and Character Inventory/1218 was administered. - Results: Moderate correlations were found between Junior Temperament and Character Inventory scales in adolescence and NYLS-derived factors in childhood. The psychosocial risk load seemed to influence the expression of novelty seeking or corresponding NYLS-derived factors, whereas the obstetric risks did not contribute to variation in temperament. Our findings further support highly sex-specific gene x environment interactions on temperament in the developmental course. - Conclusion: The content of our NYLS-derived factors and the specific type of association across different temperament constructs fit into the increasing consensus regarding a small number of higher-order temperamental traits.

In a high-risk community sample, we examined the role of regulative temperament and emotionality as well as the extent of gender specificity in the development of externalizing problems. 151 boys and 157 girls born at differing degrees of obstetric and psychosocial risk were followed from birth into adolescence. In infancy and childhood, NYLS- derived temperamental characteristics were assessed by a highly structured parent interview and standardized behavioral observations. At age 15 years, externalizing problems were measured by the Child Behavior Checklist. As revealed by multiple linear regression and logistic regression, low regulative abilities predicted adolescent behavioral and attentional problems over and above obstetric and psychosocial risks. Gender specificity was found in the strength of the association rather than in the kind with a stronger long-term prediction from infant and toddler temperament in girls. Compared to regulative abilities, temperament factors describing aspects of mood and fear/withdrawal versus approach tendencies played a minor role in the development of externalizing problems. Findings are discussed in terms of gender-specific risk factors and possible differential developmental trajectories to subtypes of disruptive behavior.
