Measuring Anxiety in Children: The Importance of Separate Mother and Father Reports

Psychometric accuracy of the Dutch Child and Adolescent Trauma Screener

Objective: The aim of this study is to investigate the psychometrics of the Dutch version of the Child and Adolescent Trauma Screener (CATS-2). By this, an international recognized instrument to screen symptoms of post-traumatic stress (PTSS) in children and adolescents according to the Diagnostic and Statistical Manual for Mental Disorders, 5th edition (DSM-5) becomes available for Dutch youth.Procedure and Method: Based on the validated CATS-2 we established the Dutch version, named the KJTS. A total of 587 children and adolescent, age 7-21, and 658 caregivers referred to mental health care services in Amsterdam was included in the study to examine psychometric properties. The construct was tested by confirmatory factor analysis (CFA). Furthermore reliability, convergent-divergent patterns and diagnostic test accuracy were examined.Results: The underlying DSM-5 factor structure with four symptom clusters (re-experiencing, avoidance, negative alterations in mood and cognitions, hyperarousal) was supported by CFA showing a good fit for the selfreport (CFI = .95, TLI = .94), and an acceptable fit for the caregiver report (CFI = .90, TLI = .89). The KJTS showed excellent reliability (alpha = .92) on both selfreport and caregiver report. The convergent-discriminant validity pattern showed medium to strong correlations with measures of internalization problems, such as anxiety and affective problems (r = .44-.72) and low to medium correlations with externalizing symptoms (r = .21-.36). The ROC-curve analysis has proven a good accuracy (AUC = .81; n = 106).Discussion and conclusion: This study demonstrates the psychometric accuracy of the KJTS in a Dutch clinical population. The KJTS reflects adequately the dimensionality of PTSD as described in the DSM-5, with a good fit for selfreports, an acceptable fit for caregiver reports, excellent reliability and sufficient validity. Limitations are described. The outcomes support the use of the KJTS in research and clinical practice for screening and monitoring of PTSS.

Parent Gender and Assessment of Children's Health

Caregiver-reported data on children's health are typically provided by mothers. We investigated whether measures of children's health would significantly differ between mother and father respondents to a nationally representative survey. This study used de-identified data on children age 0 to 17 years from the 2016-2019 National Survey of Children's Health (NSCH). The primary exposure was whether the survey was completed by the child's father (cases) or mother (controls). Outcome variables included general health, special health care needs (SHCN), and unmet health care needs. We identified 85 191 children meeting inclusion criteria, of whom 35.1% had a father respondent. After propensity score matching, 27 738 children with a father respondent were matched to an equal size group of children with a mother respondent. On conditional logistic regression analysis of the matched sample, we found that poor health, SHCN, and unmet health care needs were less likely to be reported for children in the sample by father respondents.

Agreement, Stability, and Validity of Parent- and Youth-Reported Anxiety Symptoms from Childhood to Adolescence

The current study examined changes in the agreement, stability, and concurrent and predictive validity of parent- and self-reports on a frequently used measure of youth anxiety symptoms, the Screen for Child Anxiety Related Emotional Disorders (SCARED), from age 9 to 15. A community sample of 531 families (youth, mothers, and fathers) completed the SCARED and a semi-structured diagnostic interview when children were ages 9, 12, and 15. Agreement between youth and each parent on youth anxiety symptoms was weak at age 9 (r = 0.12-0.17), but moderate at age 12 (r = 0.31-0.36) and 15 (r = 0.31-0.46); mother-father (r = 0.50-0.53) agreement was greater than youth-parent agreement at every wave. Stability of youth-reported symptoms was low between age 9 and 12 (r = 0.25), but much higher from age 12 to 15 (r = 0.57); mother- and father-reported youth anxiety symptoms demonstrated high stability (r = 0.53-0.74) at both intervals. Self- and parent-reported youth symptoms were both significantly associated with youth anxiety disorder status, cross-sectionally and prospectively. When considered simultaneously at age 9, only parent-reported anxiety symptoms uniquely predicted concurrent and subsequent youth anxiety diagnoses. However, by age 12, parent- and youth-reported anxiety symptoms were each independently associated with concurrent and subsequent anxiety diagnoses. Agreement, stability, and concurrent and predictive validity of youth self-reported anxiety symptoms are poorer than parent-reports in middle childhood, but comparable by middle adolescence. However, all reporters provide unique information about youth anxiety at each of the developmental periods examined.

Frequency and Correlates of Fathers' Accommodation in Pediatric Anxiety Disorders

Previous studies investigating family accommodation (FA) in pediatric anxiety disorders have primarily relied on mothers' reports, while data on FA by fathers remains scarce. We examined the frequency and correlates of fathers' FA of anxious children and compared fathers' and mothers' reports of FA. Participants were 69 parents of treatment-seeking children and adolescents with a primary anxiety disorder. FA was highly prevalent amongst fathers, with the majority of fathers participating in symptom-related behaviors and modifying family routines due to child anxiety. Fathers' accommodation levels were significantly correlated with fathers' reports of child internalizing symptoms, child externalizing symptoms, and fathers' own anxiety symptoms. Fathers' and mothers' reports of FA were moderately correlated, whereas their reports of their respective distress related to the need to accommodate were only weakly correlated. Fathers reported a significantly lower frequency of FA than did mothers. These findings highlight the importance of obtaining reports from both fathers and mothers when assessing FA. Results are particularly relevant to family-focused and parent-based interventions designed to address and reduce FA amongst parents of clinically anxious children.

How Anxious are German Preschool Children?

The experience of fear is universal and is among the earliest of all forms of psychopathology, if excessively present. To prevent negative developmental outcomes due to early-onset excessive fears in children, it is important to systematically assess these experiences as early as possible. Using the preschool anxiety scale (PAS), we aimed to assess the frequency and structure of anxiety symptoms of 489 preschool-aged children raised in their biological family and 88 raised in foster care (as a high-risk sample) in Germany. While these young children displayed the same types of anxiety most commonly as young children in other countries, the overall occurrence seems to be reported less often by parents in Germany compared to parents from other countries. Anxiety symptoms clustered into five correlated factors (generalized anxiety, social anxiety, obsessive-compulsive disorder (OCD), physical injury fear and separation anxiety). Young children in foster care exhibited more OCD and significantly less social anxiety symptoms indicating early repetitive and social disturbances in children in foster care.

Moving With Confidence: How Does Anxiety Impede Performance in Individuals With Developmental Coordination Disorder (DCD)?

Purpose of Review

It is well-established that anxiety levels are higher among people with developmental coordination disorder (DCD) compared to their peers. However, it is unclear whether this anxiety influences movement and behaviour. The purpose of this paper is to review studies demonstrating the influence of anxiety on movement and/or behaviour in non-DCD and DCD populations.

Recent Findings

When considering non-DCD literature, many studies have illustrated the influence of anxiety on movement. Only two papers were found which explicitly aimed to consider the influence of anxiety on movement in a DCD population. These findings are described and explored against a backdrop of the wider research field.

Summary

This paper has highlighted the potential role of anxiety in constraining movement patterns in DCD. While a great deal more evidence is needed before definitive conclusions, there is emerging evidence that motor behaviour may be related to task-specific anxiety in children with DCD.

Exploration of Caregiver Interrater Agreement and Test-Retest Reliability on the Infant Cleft Observer Outcomes (iCOO)

Caregiver and observer-reported measures are frequently used as outcomes for research on infants and young children who are unable to report on their own health. Our team developed the Infant with Clefts Observation Outcomes Instrument (iCOO) for infants with cleft lip with or without cleft palate. This exploratory study compared test-retest and interrater reliabilities to inform whether differences in caregiver perspective might affect the iCOO.

This study is a secondary analysis comparing caregiver interrater agreement to test-retest reliability. Twenty-five pairs of caregivers completed the iCOO before surgery, 1 week later for test-retest reliability, 2 days after surgery, and 2 months after surgery. Reliability was assessed using intraclass correlations (ICCs) and t-tests were used to compare ratings between caregivers.

Infants had cleft lip (28%) or cleft lip and palate (72%). Primary caregivers were predominantly mothers (92%) and secondary caregivers were predominantly fathers (80%). Test-retest reliability met psychometric standards for most items on the iCOO (81%-86% of items). Caregiver agreement on the iCOO items was lower than test-retest reliability (33%-46% of items met psychometric standards). Caregivers did not systematically differ in whether they rated infants as healthier or less healthy than the other caregiver (5%-16% of items had statistically significant differences).

Caregivers used the measure consistently, but had different experiences and perceptions of their infant's health and functioning. Future studies are needed to explore mechanisms for the differences in test-retest and interrater reliability. Whenever possible, the same caregiver should provide ratings of the infant, including on the iCOO.

Parent reports of children's emotional and behavioral problems in a low- and middle- income country (LMIC): An epidemiological study of Nepali schoolchildren

Background

As epidemiological data on child mental health in low- and middle-income countries are limited, a large-scale survey was undertaken to estimate the prevalence and amount of child emotional and behavioral problems (EBP) in Nepal as reported by the parents.

Methods

3820 schoolchildren aged 6–18 years were selected from 16 districts of the three geographical regions of Nepal, including rural, semi-urban and urban areas. We used the Nepali version of the Child Behavior Checklist (CBCL)/6-18 years as screening instrument. Comparisons of child problems between genders and between the seven largest castes and ethnic groups were carried out by analysis of variance. Prevalence was computed based on American norms.

Results

Adjusted prevalence of Total Problems was 18.3% (boys: 19.1%; girls:17.6%). The prevalence of internalizing problems was higher than externalizing problems. The mean scores of Total, Externalizing, and Internalizing problems were 29.7 (SD 25.6), 7.7 (SD 8.0), and 9.1 (SD 8.1), respectively. The Khas Kaami (Dalit) group scored the highest, and the indigenous Tharu group scored the lowest on all scales. In the Mountains and Middle Hills regions, problem scores were higher in the rural areas, whereas in the Tarai region, they were higher in the urban areas.

Conclusion

The prevalence and magnitude of emotional and behavioral problems in Nepali children were found to be high compared to findings in meta-analyses worldwide. Problem scores varied according to gender, castes /ethnic groups, and living areas. Our findings highlight the need for a stronger focus on child mental problems in a low-and middle-income country like Nepal.

Building Emotional Resilience in Youth in Lebanon: a School-Based Randomized Controlled Trial of the FRIENDS Intervention

In Lebanon, approximately one in four adolescents suffers from a psychiatric disorder. Alarmingly, 94% of adolescents with a mental disorder have not sought any treatment. This study assessed the effectiveness of an evidence-based school-based universal mental health intervention (the FRIENDS program) in reducing depression and anxiety symptoms in middle school students in Lebanon. A total of 280 6th graders aged 11-13 years were recruited from 10 schools in Beirut. Schools were matched on size and tuition and randomly assigned to intervention or control groups. The FRIENDS program was translated into Arabic, adapted, and then implemented by trained mental health professionals during 10 classroom sessions over 3 months. We assessed sociodemographic and relevant psychological symptoms by self-report, using the Scale for Childhood Anxiety and Related Disorders (SCARED), Mood and Feelings Questionnaire (MFQ), and Strengths and Difficulties Questionnaire (SDQ), at baseline. We re-administered these scales at 3 months post-intervention. There was a significant time × group interaction for the SDQ emotional score (p = 0.011) and total MFQ score (p = 0.039) indicating significant improvement in depressive and emotional symptoms in the intervention group. Subgroup analysis by gender showed a significant time × group interaction for the total SCARED score (p = 0.025) in females but not in males (p = 0.137), consistent with a reduction of anxiety symptoms in this stratum of the intervention group as compared with the control group. The FRIENDS program was effective in reducing general emotional and depressive symptoms among middle school students in this Lebanese study population. This intervention provides an opportunity for promoting mental health in Lebanese schools and reducing the treatment gap in mental health care.

The Association between Child and Parent Psychiatric Disorders in Families Exposed to Flood and/or Dioxin

Associations of disaster mental health sequelae between children and their parents have been demonstrated, but not using full diagnostic assessment. This study examined children and their parents after a series of disasters in 1982 to investigate associations of their psychiatric outcomes. Members of 169 families exposed to floods and/or dioxin or no disaster were assessed in 1986–1987 with structured diagnostic interviews. This vintage dataset collected several decades ago provides new information to this field because of the methodological rigor that is unparalleled in this literature. Disaster-related PTSD and incident postdisaster disorders in children were associated, respectively with disaster-related PTSD and incident postdisaster disorders in the chief caregiver and mother. More flood-only than dioxin-only exposed parents reported great harm by the disaster, but neither children nor parents in these two groups differed in incident psychiatric disorders. Although this study did not determine the direction of causal influences, its findings suggest that clinicians working with disaster-exposed families should work with children and adult members together, as their mental health outcomes may be intertwined.

Evaluation of state and trait anxiety levels of parents and children before electroencephalography procedures: A prospective study from a tertiary epilepsy center

BACKGROUND

Inadequate or misinformation about electroencephalography (EEG) and epilepsy may lead to anxiety in children and their parents. The purpose of this study was to make a simultaneous evaluation of the anxiety levels of children and parents before EEG procedures and to make a brief assessment of their knowledge about EEG.

METHODS AND MATERIALS

Children aged between 8 and 18 years who were referred for EEG tests at Department of Pediatric Neurology, Gazi University Faculty of Medicine, Ankara, Turkey and their parents were included in the study, prospectively. Data were collected through Personal Information Forms; an EEG questionnaire form, which questioned the knowledge of the participants about EEG; the Spielberger's State-Trait Anxiety Inventory (STAI) to determine anxiety levels of the parents; and the State-Trait Anxiety Inventory for Children-State form (STAIC) to determine the anxiety levels of the children. The following parameters were collected in a database: demographic data about children and parents (sex, age), indication of suspected diagnosis on EEG request (i.e., the referral diagnosis), history of epilepsy, number of EEG recordings, and results of previous EEG recordings. The state and trait anxiety test results of the children were compared between the girls and boys, between age groups, and their parents' results in terms of both trait and state anxiety in terms of EEG, sex, ages, educational levels, and working.

RESULTS

Eighty-five children (mean age: 13.25 ± 3.02 years) and 85 parents (mean age: 41.16 ± 7.65 years) were included in the study. The children's mean trait anxiety score was 32.51 ± 8.09, and the mean state anxiety score was 34.97 ± 7.62. Half of the children who had a trait anxiety score of ≤30 points had increased state anxiety levels because they received more than 30 points in the state anxiety evaluation score. No significant differences were found between the boys and girls in terms of the state and trait anxiety scores (p > 0.05). The parents' mean trait anxiety score was 39.16 ± 7.74, and the mean state anxiety score was 42.74 ± 6.22. Forty (47%) parents were found to have trait anxiety, and 52 (61.2%) parents had state anxiety before the EEG. The trait anxiety score of the mothers was statistically significantly higher than that of the fathers (p < 0.01). The investigation of the knowledge level of both parents and children about EEG demonstrated some misunderstandings or points of insufficiency.

CONCLUSION

The present study revealed that both parents and children had insufficient knowledge about EEG, and the procedure caused anxiety for both the parents and children. When EEG procedures are requested, parents and children should be given brief information about EEG and epilepsy. We think that in this way, the knowledge of both parents and children about this issue may be increased and their anxiety may be decreased.

The explanatory role of anxiety sensitivity in the association between effortful control and child anxiety and depressive symptoms

The present study examined the underlying role of anxiety sensitivity in the association between effortful control and anxiety and depressive symptoms in a sample of clinically anxious children. It was hypothesized that effortful control would exert an indirect effect through anxiety sensitivity in relation to child anxiety and depressive symptoms. Clinically anxious children (N= 105; Mage = 10.09 years, SD = 1.22; 56.7% female; 61% ethnic minority) and their mothers completed a diagnostic interview and a battery of questionnaires that included self- and mother-ratings of child effortful control, anxiety sensitivity, and anxiety and depressive symptoms. The indirect effect of effortful control via anxiety sensitivity on child anxiety and depressive symptoms was significant across child- and mother-completed measures. Among clinically anxious youth, greater effortful control was related to lower anxiety sensitivity, which was related to lower anxiety and depressive symptoms. Future work should evaluate whether targeting effortful control leads to clinically meaningful reductions in anxiety sensitivity and child anxiety and depressive symptoms.

A Comparison of Attachment representations to Mother and Father using the MCAST

The aim of the current study was to examine the factorial structure of the Manchester Child Attachment Story Task (MCAST), using a father doll to address the child's attachment representation to father. While the MCAST, a doll story completion task measuring attachment representations in early childhood, has been validated for use with a mother doll, its use for assessing attachment to father is relatively unexplored. Thus, an additional aim was to compare the factorial structure of the child's attachment representation to father and mother, respectively. We analyzed data from 118 first-grade children who underwent counterbalanced administration of the MCAST with a mother and father doll, respectively, within a period of three months. Exploratory factorial analysis revealed similar, three-factor solutions for attachment to father and mother, with a first factor capturing the child's (scripted) knowledge of secure base/safe haven and a second factor reflecting intrusive and conflict behavior. The third factor was different in the father and mother representations, capturing self-care and role-reversal in attachment to father and disorganization in attachment to mother. Findings support the potential usefulness of the MCAST for exploring the father-child relationship and highlight a need for further research on early attachment representations to father.

Children's DAT1 Polymorphism Moderates the Relationship Between Parents' Psychological Profiles, Children's DAT Methylation, and Their Emotional/Behavioral Functioning in a Normative Sample

Parental psychopathological risk is considered as one of the most crucial features associated with epigenetic modifications in offspring, which in turn are thought to be related to their emotional/behavioral profiles. The dopamine active transporter (DAT) gene is suggested to play a significant role in affective/behavioral regulation. On the basis of the previous literature, we aimed at verifying whether children’s DAT1 polymorphisms moderated the relationship between parents’ psychological profiles, children’s emotional/behavioral functioning, and DAT1 methylation in a normative sample of 79 families with school-age children (Ntot = 237). Children’s biological samples were collected through buccal swabs, while Symptom Check-List-90 item Revised, Adult Self Report, and Child Behavior Check-List/6–18 was administered to assess parental and children’s psychological functioning. We found that higher maternal externalizing problems predicted the following: higher levels of children’s DAT1 methylation at M1, but only among children with 10/10 genotype; higher levels of methylation at M2 among children with 10/10 genotype; while lower levels for children with a 9-repeat allele. There was also a positive relationship between fathers’ externalizing problems and children’s externalizing problems, only for children with a 9-repeat allele. Our findings support emerging evidence of the complex interplay between genetic and environmental factors in shaping children’ emotional/behavioral functioning, contributing to the knowledge of risk variables for a child’s development and psychological well-being.

Nash-wo-Numa (childhood growth & development) study protocol: factors that impact linear growth in children 9 to 15 years of age in Matiari, Pakistan

INTRODUCTION

Adolescence is a time of significant physical and emotional change, and there is emerging concern that adolescents living in low- and middle-income countries (LMIC) may face substantial challenges in relation to linear growth and mental health. Data on the global burden of stunting after 5 years of age are limited, but estimates suggest up to 50 per cent of all adolescents in some LMIC are stunted. Additionally, many LMIC lack robust mental health care delivery systems. Pakistan has one of the world's largest populations of adolescents (10 to 19 years) at approximately 40 million. The Nash-wo-Numa study's primary objective is to assess the prevalence and risk factors for stunting among early adolescents in rural Pakistan. The study also aims to determine the prevalence of poor mental health and identify factors associated with common mental health concerns during the childhood to adulthood transition.

METHODS

This cross-sectional study will include girls (n= 738) 9.0 to 14.9 years of age and boys (n=687) 10.0 to 15.9 years of age who live in the rural district of Matiari, Pakistan. Participants will be assessed for anthropometrical measures, puberty development, nutritional biomarkers as well as symptoms of depression, anxiety and trauma using validated scales.

ETHICS AND DISSEMINATION

The proposed study aims to complete the picture of child and adolescent health concerning linear growth and mental health by including puberty indicators. Ethics approval has been granted by the Ethics Review Committee at the Aga Khan University, Karachi, Pakistan, #5251-WCH-ERC-18 and Research Ethics Board at SickKids Hospital, Toronto, Canada, #:1000060684. Study results will be presented at relevant conferences and published in peer-reviewed journals.

The Screen for Child Anxiety Related Emotional Disorders (SCARED): Informant Discrepancy, Measurement Invariance, and Test-Retest Reliability

The Screen for Child Anxiety Related Emotional Disorders (SCARED) is a measure widely used to assess childhood anxiety based on parent and child report. However, while the SCARED is a reliable, valid, and sensitive measure to screen for pediatric anxiety disorders, informant discrepancy can pose clinical and research challenges. The present study assesses informant discrepancy, measurement invariance, test-retest reliability, and external validity of the SCARED in 1092 anxious and healthy parent-child dyads. Our findings indicate that discrepancy does not vary systematically by the various clinical, demographic, and familial variables examined. There was support for strict measurement invariance, strong test-retest reliability, and adequate external validity with a clinician-rated measure of anxiety. These findings further support the utility of the SCARED in clinical and research settings, but low parent-child agreement highlights the need for further investigation of factors contributing to SCARED informant discrepancy.

Determining at What Age Children Provide Sound Self-Reports: An Illustration of the Validity-Index Approach

In psychological assessment of children, it is pivotal to establish from what age on self-reports can complement or replace informant reports. We introduce a psychometric approach to estimate the minimum age for a child to produce self-report data that is of similar quality as informant data. The approach makes use of statistical validity indicators such as person-fit and long-string indices, and can be readily applied to data commonly collected in psychometric studies of child measures. We evaluate and illustrate the approach, using self-report and informant-report data of the PedsQL, a pediatric health-related quality of life measure, from 651 child-mother pairs. To evaluate the approach, we tested various hypotheses about the validity of the self-report data, using the Gnp person-fit index as the validity indicator and the mother informant-data as a benchmark for validity. Results showed that Gnp discriminated between self-reports of younger and older children, between self-reports of children that completed the PedsQL alone or with a parent, and between self-reports and informant reports. We conclude that the validity-index approach has good potential for future applications. Future research should further evaluate the approach for different types of questionnaires (e.g., personality inventories) and using different validity indices (e.g., response-bias indices).

Wie gut stimmen Eltern- und Kinderurteile bei der Einschätzung von Kinderängsten überein?

Zusammenfassung. Im Rahmen der vorliegenden Studie soll die Interrater-Reliabilität des Eltern- und Kinderurteils für alle Skalen des Bereichsspezifischen Angstfragebogens für Kinder und Jugendliche (BAK) und der Einfluss von möglichen Variablen (Alter und Geschlecht des Kindes) auf die Übereinstimmung von Eltern- und Kindurteil ermittelt werden. Es wurden 572 Kinder und Jugendliche (295 Mädchen; 277 Jungen) im Alter von 9 bis 16 Jahren aus der Allgemeinbevölkerung und ihre Eltern anhand des BAK zu den Ängsten befragt. Berechnet wird die Interrater-Reliabilität sowohl für die intervallskalierten Daten (T-Werte) als auch für die daraus resultierenden kategorialen Daten. Es zeigt sich ausschließlich ein Alterseffekt auf die Übereinstimmung in den Punktwerten für die Skala Naturgewalten des BAK. Für alle Skalen des BAK mit Ausnahme der Skalen Medizinischer Bereich und Trennung/Unbekanntes konnte ein Geschlechtseffekt belegt werden. Die Interrater-Reliabilitäten sind als gering bis mittelmäßig einzustufen (ICC = .33 bis .62; Krippendorffs αü = .25 bis .57; Gewichtetes Cohens ϰ = .29 bis .58). Die Beurteiler-Übereinstimmungen fallen über alle Skalen hinweg bei den Mädchen höher aus als bei den Jungen. Die Ergebnisse verdeutlichen, dass es sinnvoll ist, bei der Beurteilung der Angstsymptomatik eines Kindes sowohl das Selbsturteil als auch das Elternurteil einzuholen.

DNA Methylation at the DAT Promoter and Risk for Psychopathology: Intergenerational Transmission between School-Age Youths and Their Parents in a Community Sample

BACKGROUND

The effect of gene polymorphisms and promoter methylation, associated with maladaptive developmental outcomes, vary depending on environmental factors (e.g., parental psychopathology). Most studies have focused on 0- to 5-year-old children, adolescents, or adults, whereas there is dearth of research on school-age youths and pre-adolescents.

METHODS

In a sample of 21 families recruited at schools, we addressed parents' psychopathological symptoms (through SCL-90-R); offspring emotional-behavioral functioning (through CBCL-6-18); dopamine transporter gene (DAT1) for epigenetic status of the 5'-untranslated region (UTR) and for genotype, i.e., variable number of tandem repeats polymorphism at the 3'-UTR. Possible associations were explored between bio-genetic and psychological characteristics within the same individual and between triplets of children, mothers, and fathers.

RESULTS

DAT methylation of CpG at positions M1, M6, and M7 in mothers was correlated with maternal (phobic) anxiety, whereas in fathers' position M6 was related to paternal depression, anxiety, hostility, psychoticism, and higher Global Severity Index (GSI). No significant correlations were found between maternal and offspring DAT methylation. Significant correlations were found between fathers' methylation at CpG M1 and children's methylation at CpG M6. Linear regressions showed that mothers and fathers' GSI predicted children's methylation at CpG sites M2, M3, and M6, whereas fathers' GSI predicted children's methylation at CpG sites, particularly M1, M2, and M6. Moreover, offspring methylation of DAT at CpG M2 predicted somatic complaint, internalizing and attention problems; methylation of DAT at CpG M6 predicted withdraw.

CONCLUSION

This study may have important clinical implication for the prevention and treatment of emotional-behavioral difficulties in children, as it adds to previous knowledge about the role of genetic and environmental factors in predicting psychopathological symptoms within non-clinical populations.
