Animated triangles: an eye tracking investigation.

We presented three types of animations on an eye tracking monitor to 31 adult participants. In line with previous work, verbal descriptions of these animations indicate that one type (theory of mind or ToM) evokes mental state attributions, while another type (random) does not, with an intermediate category (goal-directed) evoking a moderate amount of mental state attributions. We expected longer fixations with greater depth of processing, which we assume is required for mental state attributions. In line with this expectation we found that the ToM animations invited long fixations; the random animations invited short fixations, while the goal-directed animations invited an intermediate amount of fixations, with some clips inviting shorter and others longer fixations. These findings demonstrate that it is possible to capture systematic differences in behaviour while viewing animations not only by means of a verbal measure, but also in terms of a simple measure of eye movements.

Depressive comorbidity in preschool anxiety disorder

Background The threshold for clinical relevance of preschool anxiety has recently come under increasing scrutiny in view of large variations in prevalence estimates. We studied the impact of presence/absence of additional depressive comorbidity (symptoms and/or diagnosis) on preschoolers with anxiety disorders in relation to clinical phenomenology, family, and peer problems compared to healthy controls. Method A population of 1738 preschoolers were screened and oversampled for internalizing symptoms from community sites, yielding a sample of 236 children. Results Using a multi-informant approach (mother, father, teacher, child), we found evidence that children with anxiety disorders and depressive comorbidity display a greater internalizing symptom-load, more peer problems and live in families with more psychosocial impairment (poor family functioning, family adversity, maternal mental health problems). The pure anxiety group was merely dissociable from controls with regard to internalizing symptoms and family adversity. Conclusion The presence of depressive comorbidity in anxiety disorders may mark the transition to a more detrimental and impairing disorder at preschool age.

FKBP5 polymorphisms moderate the influence of adverse life events on the risk of anxiety and depressive disorders in preschool children.

FKBP5 is thought to be involved in the pathogenesis of stress-related disorders. Studies have shown that FKBP5 genotypes moderate the risk of post-traumatic stress disorder and depression in traumatized adults. We aimed to replicate this finding in a sample of preschool children. Parents of preschoolers (N = 186) were interviewed using the Preschool Age Psychiatric Assessment (PAPA) to evaluate the presence of anxiety and depressive disorders and to quantify the childs exposure to adverse events. All FKBP5 polymorphisms showed significant interactions with mild to moderate life events, but not with severe life events, in predicting the risk of anxiety and/or depressive disorders (p = 0.003-0.019). Children who experienced a high number of mild to moderate life events had a higher risk of developing an anxiety and/or depressive disorder if they were carriers of the minor allele compared to major allele homozygotes. Results indicate that genetic variation in FKBP5 influences the risk of anxiety and/or depressive disorders in preschool age by altering the sensitivity to the deleterious effects of mild to moderate adverse events. In case of severe life events, the FKBP5 genotype does not seem to play a role, suggesting that severe life events might influence directly the risk of anxiety and/or depressive disorders independent of an FKBP5 genotype-dependent vulnerability.

Psychometric evaluation of the Generalized Anxiety Disorder Screener GAD-7, based on a large German general population sample

BACKGROUND The Generalized Anxiety Disorder Scales GAD-7 and GAD-2 are instruments for the assessment of anxiety. The aims of this study are to test psychometric properties of these questionnaires, to provide normative values, and to investigate associations with sociodemographic factors, quality of life, psychological variables, and behavioral factors. METHODS A German community sample (n=9721) with an age range of 18-80 years was surveyed using the GAD-7 and several other questionnaires. RESULTS Confirmatory factor analyses confirmed the unidimensionality and measurement invariance of the GAD-7 across age and gender. Females were more anxious than males (mean scores: M=4.07 vs. M=3.01; effect size: d=0.33). There was no linear age trend. A total of 5.9% fulfilled the cut-off criterion of 10 and above. Anxiety was correlated with low quality of life, fatigue, low habitual optimism, physical complaints, sleep problems, low life satisfaction, low social support, low education, unemployment, and low income. Cigarette smoking and alcohol consumption were also associated with heightened anxiety, especially in women. When comparing the GAD-7 (7 items) with the ultra-short GAD-2 (2 items), the GAD-7 instrument was superior to the GAD-2 regarding several psychometric criteria. LIMITATIONS The response rate (33%) was low. Because of the cross-sectional character of the study, causal conclusions cannot be drawn. A further limitation is the lack of a gold standard for diagnosing anxiety. CONCLUSIONS The GAD-7 can be recommended for use in clinical research and routine.

Short-term psychoanalytic child therapy for anxious children: a pilot study.

Few studies report treatment outcome for early childhood internalizing disorders following psychotherapy, especially psychodynamic techniques. We aimed to investigate effectiveness of a novel, developmentally appropriate, short-term psychodynamic treatment program for 4- to 10-year-olds with anxiety disorders in an outpatient setting. We conducted a quasi-experimental wait-list controlled study. Thirty children (12 females) with Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) anxiety disorders and their families received 20-25 sessions of manualized short-term Psychoanalytic Child Therapy (PaCT). We assessed outcome with standardized diagnostic interviews and parent reports of internalizing and total problems at all time points. Child puppet interviews and teacher reports were also available for pre-post treatment and follow-up analyses. While 18 families entered treatment immediately, 12 families were first wait-listed before receiving treatment. Analyses of symptom improvement were based on comparisons between groups (treatment vs. wait-list) as well as pre-post and 6-month follow-up data across all families (including wait-listed families). Among the 27 completers, 66.67% (n = 18) no longer met criteria for any anxiety disorder (59.88% in intent-to-treat analysis) while no children remitted across the wait-list interval. Parent-reported child internalizing and total problems significantly declined during treatment relative to wait-list. Child and teacher reports also revealed significant pre-post symptom reductions on internalizing and total problems. Diagnostic and symptom remission rates were maintained at 6-month follow-up except on child reports. This preliminary study adds to a growing database showing that psychodynamic treatments may offer an effective line of treatment for childhood internalizing symptoms and disorders in the eyes of clinicians, children, parents, and teachers.

The interaction of social risk factors and HPA axis dysregulation in predicting emotional symptoms of five- and six-year-old children

OBJECTIVE We examined the links of social relational (family environment and peer victimization) and neuroendocrinological (HPA axis dysregulation) risk factors to childrens emotional symptoms. We placed special emphasis on the joint effects of these risk factors with respect to the emergence and course of the emotional symptoms. METHODS One hundred and sixty-six children were interviewed (Berkeley Puppet Interview) at age 5 and 6. Teachers and parents completed the Strengths and Difficulties Questionnaire. Parents completed the Family Environment Scales. Peer victimization was assessed by teacher and child reports. Childrens saliva cortisol was measured before and after a highly structured story completion task which targeted their cognitive emotional representations of family conflicts. RESULTS In the cross-sectional analyses, negative family environment, peer victimization, and cortisol increase during the story completion task independently contributed to the variance of emotional symptoms. There was a significant interaction effect between family environment and cortisol increase: those six-year-olds who had experienced an unfavorable family environment only showed high levels of emotional symptoms if they exhibited a cortisol increase during the story completion task. In the longitudinal analysis, peer victimization at age 5 predicted an increase of emotional symptoms at age 6, but only for those children who exhibited a blunted cortisol response a year earlier. CONCLUSIONS Negative family environment and peer victimization proved to be independently associated with emotional symptoms. HPA axis reactivity differentially moderated these associations. Therapeutic strategies should take the interaction between negative relational experiences and biological susceptibility to stress into account.

Maternal Weight Predicts Children's Psychosocial Development via Parenting Stress and Emotional Availability

Introduction: Maternal obesity has been shown to be a risk factor for obesity in children and may also affect childrens psychosocial outcomes. It is not yet clear whether there are also psycho-emotional mechanisms explaining the effects of maternal weight on young childrens weight and psychosocial development. We aimed to evaluate whether maternal body mass index (BMI), mother–child emotional availability (EA), and maternal parenting stress are associated with childrens weight and psychosocial development (i.e., internalizing/externalizing symptoms and social competence) and whether these predictors interact with each other. Methods: This longitudinal study included three assessment points (~11 months apart). The baseline sample consisted of N = 194 mothers and their children aged 5–47 months (M = 28.18, SD = 8.44, 99 girls). At t1, we measured maternal weight and height to calculate maternal BMI. We videotaped mother–child interactions, coding them with the EA Scales (fourth edition). We assessed maternal parenting stress with the Parenting Stress Index (PSI) short form. At t1 to t3, we measured height and weight of children and calculated BMI–SDS scores. Childrens externalizing and internalizing problems (t1–t3) and social competence (t3, N = 118) were assessed using questionnaires: Child Behavior Checklist (CBCL 1.5–5), Strengths and Difficulties Questionnaire (SDQ: prosocial behavior), and a checklist for behavioral problems at preschool age (VBV 3–6: social-emotional competence). Results: By applying structural equation modeling (SEM) and a latent regression analysis, we found maternal BMI to predict higher BMI–SDS and a poorer psychosocial development (higher externalizing symptoms, lower social competence) in children. Higher parenting stress predicted higher levels of externalizing and internalizing symptoms and lower social competence. Better maternal EA was associated with higher social competence. We found parenting stress to serve as a mediator in the association between maternal weight and childrens psychosocial outcomes. Moreover, children of mothers with an elevated BMI were at greater risk of lower social competence only when their mothers showed low levels of maternal EA (moderation). Conclusion: Interventional studies are needed that investigate the causal pathways between parenting stress, mother–child interaction quality and child outcomes. These aspects might be targets to improve the psychosocial development of the offspring of overweight or obese mothers.

Maternal stress and internalizing symptoms in preschoolers: the moderating role of narrative coherence.

In the present study, we examined whether maternal psychosocial stress and childrens coherence in story-stem narratives are associated with preschool childrens internalizing symptoms and disorders, and whether narrative coherence moderates the association between maternal stress and childrens internalizing symptoms and disorders. The sample consists of 236 preschool children (129 girls, 107 boys; Mage = 5.15 years) and their mothers. Mothers completed questionnaires on their psychosocial stress burden and on child symptoms. A diagnostic interview (the Preschool Age Psychiatric Assessment; Egger & Angold, 2004) was conducted with one of the parents to assess childrens psychiatric diagnoses. Children completed 8 story stems of the MacArthur Story Stem Battery (Bretherton & Oppenheim, 2003). Story-stem narratives were coded for narrative coherence. Multivariate analyses were controlled for childrens age, gender, verbal performance, and externalizing symptoms. Results showed that maternal psychosocial stress was significantly associated with child internalizing symptoms and disorders. Neither maternal stress nor childrens internalizing symptoms or disorders were associated with narrative coherence. However, narrative coherence moderated the association between maternal stress and child internalizing symptoms. For children with more incoherent narratives, the association between maternal psychosocial stress and childrens internalizing symptoms was significantly stronger than for children with more coherent narratives. The moderation effect of narrative coherence concerning childrens internalizing disorders was found not to be significant. Our findings indicate that preschool childrens cognitive-emotional organization in dealing with relational conflict themes seems to buffer their mental health when exposed to adverse circumstances in their everyday family life.

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 (β = -.199, p < .05, R(2) = .304). Externalizing disorders had a positive association between AA baseline and cortisol increase (β = .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.

Analyzing pathways from childhood maltreatment to internalizing symptoms and disorders in children and adolescents (AMIS): a study protocol

BackgroundEffective interventions for maltreated children are impeded by gaps in our knowledge of the etiopathogenic mechanisms leading from maltreatment to mental disorders. Although some studies have already identified individual risk factors, there is a lack of large-scale multilevel research on how psychosocial, neurobiological, and genetic factors act in concert to modulate risk of internalizing psychopathology in childhood following maltreatment. To help close this gap, we aim to delineate gender-specific pathways from maltreatment to psychological disorder/resilience. To this end, we examine the interplay of specific maltreatment characteristics and psychological, endocrine, metabolomic, and (epi-)genomic stress response patterns as well as cognitive-emotional/social processes as determinants of developmental outcome. Specifically, we will explore endocrine, metabolomic, and epigenetic mechanisms leading from maltreatment to a higher risk of depression and anxiety disorders.Methods/designFour large samples amounting to a total of N = 920 children aged 4–16 years will be assessed: Two cohorts with prior internalizing psychopathology and controls will be checked for maltreatment and two cohorts with substantiated maltreatment will be checked for internalizing (and externalizing) psychopathology. We will apply a multi-source (interview, questionnaires, official records), multi-informant strategy (parents, children, teachers) to assess maltreatment characteristics (e.g., subtypes, developmental timing, chronicity) and psychopathological symptoms, supplemented with multiple measurements of risk and protective factors and cutting-edge laboratory analyses of endocrine, steroid metabolomic and epigenetic factors. As previous assessments in the two largest samples are already available, longitudinal data will be generated within the three year study period.DiscussionOur results will lay the empirical foundation for (a) detection of early biopsychosocial markers, (b) development of screening measures, and (c) multisystem-oriented interventions in the wake of maltreatment.
