What single reports from children and parents aggregate to attention deficit-hyperactivity disorder and oppositional defiant disorder diagnoses in epidemiological studies

Caregiver and youth inter-rater assessment agreement in autism spectrum disorder, developmental coordination disorder, and typical development

Youth diagnosed with autism spectrum disorder (ASD) and those with developmental coordination disorder (DCD) are at heightened risk for co-occurring mental health diagnoses, especially anxiety and attention-deficit/hyperactivity disorder (ADHD). However, caregiver-child agreement on presence of related symptoms in populations with neurodevelopmental conditions is not well understood. Here, we examine the extent to which 37 ASD, 26 DCD, and 40 typically developing children and their caregivers agree on the degree of the child's symptoms of anxiety and ADHD. All caregiver-child dyads completed the Screen for Child Anxiety Related Emotional Disorders and Conners 3 ADHD Index. Across groups, intraclass correlations indicated generally poor agreement on anxiety and ADHD symptomatology. Although youth generally reported greater internalizing symptoms (i.e., anxiety), caregivers tended to report more observable externalizing behaviors (i.e., ADHD). Together, the results of this study support the need for a multi-informant approach in assessments of anxiety and ADHD in youth with neurodevelopmental disorders.

Prevalence of oppositional defiant disorder in a sample of Spanish schoolchildren

The aim of this study is to determine the prevalence rate of ODD in school age children, and analyze the variability of the prevalence rates per informant, according to the sources of information, sex, age, and level of agreement between teachers and parents. This is an epidemiological study conducted using a community sample extracted by means of multi-stage stratified sampling. The sample consisted of 1,295 children of both sexes from 6 to 8 years old. For diagnostic evaluation, the Oppositional Defiant Disorder Rating Scale (ODDRS-IV) was used. The estimated global prevalence of ODD, detected by all sources is 16.1%. But if we consider the percentage of subjects detected by only one informant, the prevalence rate is 9.5%. The prevalence according to teachers is 5.1% (95% CI = 3.88-6.31), according to fathers is 9% (95% CI = 7.38-10.54), and according to mothers is 9.7% (95% CI = 8.02-11.29). Teachers report more boys with ODD than girls. Results support the idea of high variability in ODD prevalence rates. Our findings suggest that parents are more prone to detect the disorder than teachers, and that boys present ODD more frequently than girls, only when they are evaluated by their teachers.

ADHD prevalence in Lebanese school-age population

OBJECTIVE

The authors conducted an epidemiological study in Lebanon to estimate ADHD prevalence in school-age population.

METHOD

They selected 1,000 children aged between 6 and 10 years, admitted in several schools in Lebanon. In each district, they randomly chose five schools, and in each school two classes. From each class, 10 children were included randomly in the population of the study. For each child, an ADHD-Rating Scale-IV School version was filled by a main teacher. The Home version was filled by the child's parents.

RESULTS

The prevalence of ADHD Inattentive subtype was 3 per 1,000, Hyperactive-Impulsive subtype 12 per 1,000, and ADHD Combined subtype 17 per 1,000. ADHD was significantly more prevalent in boys than in girls.

CONCLUSION

This is the first epidemiological study to be conducted in Lebanon to estimate the prevalence of ADHD among children.

Transgenerational consequences of PTSD: risk factors for the mental health of children whose mothers have been exposed to the Rwandan genocide

Background

Understanding how parental Posttraumatic Stress Disorder (PTSD) may or may not affect the development and mental health in the offspring is particularly important in conflict regions, where trauma-related illness is endemic. In Rwanda, organised atrocities and the genocide against the Tutsi of 1994 have left a significant fraction of the population with chronic PTSD. The aim of the present investigation was to establish whether PTSD in mothers is associated with symptoms of depression, anxiety, and aggressive and antisocial behaviour in their children.

Methods

A community sample of 125 Rwandan mothers who experienced the genocide of 1994 and their 12-year-old children were interviewed. Using a structured interview, symptoms of maternal PTSD and children’s depression, anxiety, and aggressive and antisocial behaviour were assessed by trained and on-site supervised local B.A. psychologists. The interview also included a detailed checklist of event types related to family violence.

Results

In showing that a maternal PTSD was not associated with child’s psychopathology, the results contradict the assumption of straight “trans-generational trauma transmission”. Instead, a child’s exposure to maternal family violence posed a significant risk factor for a negative mental health outcome. Furthermore, it was not maternal PTSD-symptoms but mother’s exposure to family violence during her own childhood that was associated with the magnitude of adversities that a child experiences at home.

Conclusions

Contrary to a simple model of a trans-generational transmission of trauma, neither maternal PTSD nor maternal traumatic experiences were directly associated with symptoms of anxiety, depression, or antisocial and aggressive behaviour in the children. Instead, the present results suggest a relationship between parental child rearing practices and children’s mental health. Furthermore, the study details the “cycle of violence”, showing a significant link between maternal violence against a child and its mother’s experience of childhood maltreatment.

Epidemiological modelling of attention-deficit/hyperactivity disorder and conduct disorder for the Global Burden of Disease Study 2010

BACKGROUND

The most recent Global Burden of Disease Study (GBD 2010) is the first to include attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) for burden quantification. We present the epidemiological profiles of ADHD and CD across three time periods for 21 world regions.

METHODS

A systematic review of global epidemiology was conducted for each disorder (based on a literature search of the Medline, PsycInfo and EMBASE databases). A Bayesian metaregression tool was used to derive prevalence estimates by age and sex in three time periods (1990, 2005 and 2010) for 21 world regions including those with little or no data. Prior expert knowledge and covariates were applied to each model to adjust suboptimal data. Final prevalence output for ADHD were adjusted to reflect an equivalent value if studies had measured point prevalence using multiple informants while final prevalence output for CD were adjusted to reflect a value equivalent to CD only.

RESULTS

Prevalence was pooled for males and females aged 5-19 years with no difference found in global prevalence between the three time periods. Male prevalence of ADHD in 2010 was 2.2% (2.0-2.3) while female prevalence was 0.7% (0.6-0.7). Male prevalence of CD in 2010 was 3.6% (3.3-4.0) while female prevalence was 1.5% (1.4-1.7). ADHD and CD were estimated to be present worldwide with ADHD prevalence showing some regional variation while CD prevalence remained relatively consistent worldwide.

CONCLUSIONS

We present the first prevalence estimates of both ADHD and CD globally and for all world regions. Data were sparse with large parts of the world having no estimates of either disorder. Epidemiological studies are urgently needed in certain parts of the world. Our findings directly informed burden quantification for GBD 2010. As mental disorders gained increased recognition after the first GBD study in 1990, the inclusion of ADHD and CD in GBD 2010 ensures their importance will be recognized alongside other childhood disorders.

Examination of a cutoff score for the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a non-clinical Spanish population

We aimed to find a valid cutoff score for the Screen for Child Anxiety Related Emotional Disorders, child (SCARED-C) and parent (SCARED-P) Spanish versions for detecting Anxiety Disorders (AD) in a non-clinical population. The predictive accuracy of the SCARED-C and SCARED-P was assessed using the Area Under the Curve (AUC) of ROC curves. In general, the predictive accuracy of the SCARED-C (full version, short version, and four factors) was good and better than that of the SCARED-P. To differentiate between children who meet the diagnostic criteria for any AD and children who do not, we propose cutoff scores of 25 and 17 for the SCARED-C and SCARED-P, respectively. The sensitivities are 75.9% and 62.8%, and the specificities are 68.5% and 69.5%. The SCARED-C factor that had the best predictive accuracy was Somatic panic followed by Separation Anxiety, Generalized Anxiety and Social Phobia. The SCARED-P factor with the best predictive accuracy was Separation Anxiety. The results support the use of SCARED-C as a screening test for Anxiety disorders while SCARED-P should only be used as complementary information.

Adolescents' perceptions of parental behavior: psychometric properties of the short Egna Minnen Beträffande Uppfostran-Adolescent version (S-EMBU-A) in a clinical sample

OBJECTIVES

The aim of this study was to evaluate the psychometric properties of the Spanish version of the short Egna Minnen Beträffande Uppfostran-Adolescent version (S-EMBU-A) in a clinical context.

METHODS

The S-EMBU-A is a 22-item self-report questionnaire, based on the original 64-item EMBU-A, that assesses perceived parental rearing style in adolescents, comprising 3 subscales (Rejection, Emotional Warmth, and Overprotection). The questionnaire was administered to a clinical sample of 281 Spanish psychiatric outpatients aged 13 to 18 years. Confirmatory factor analysis was performed, analyzing the adolescents' reports about their parents' rearing style.

RESULTS

Confirmatory factor analysis yielded an acceptable fit to data of the 3-factor model (comparative fit index = 0.90; root mean squared error of approximation = 0.054) and parameters were equivalent for the ratings assigned to fathers and mothers. Satisfactory internal consistency reliability was obtained for the 3 scales (Cronbach α ≥ .74). The influence of gender (of adolescents and parents) and age on scale scores was inappreciable. High scores for Rejection and low scores for Emotional Warmth were related to bad relationships with parents, absence of family support, presence of rejection, harsh discipline, and lack of parental supervision.

CONCLUSIONS

The Spanish version of S-EMBU-A can be used with psychometric guarantees to identify rearing style in psychiatric outpatients, because evidence of quality in clinical setting matches that obtained in community samples.

Perceived parental rearing style in childhood: internal structure and concurrent validity on the Egna Minnen Beträffande Uppfostran--Child Version in clinical settings

BACKGROUND

We provide the first validation data of the Spanish version of the Egna Minnen Beträffande Uppfostran--Child Version (EMBU-C) in a clinical context. The EMBU-C is a 41-item self-report questionnaire that assesses perceived parental rearing style in children, comprising 4 subscales (rejection, emotional warmth, control attempts/overprotection, and favoring subjects).

METHODS

The test was administered to a clinical sample of 174 Spanish psychiatric outpatients aged 8 to 12. Confirmatory factor analyses were performed, analyzing the children's reports about their parents' rearing style.

RESULTS

The results were almost equivalent for father's and mother's ratings. Confirmatory factor analysis yielded an acceptable fit to data of the 3-factor model when removing the items of the favoring subjects scale (root mean squared error of approximation <0.07). Satisfactory internal consistency reliability was obtained for 2 of the 3 scales, rejection and emotional warmth (Cronbach alpha >.73), whereas control attempts scale showed lower values, as in previous studies. The influence of sex (of children and parents) on scale scores was inappreciable and children tended to perceive their parents as progressively less warm as they grew older. As predicted, the scores for rejection and emotional warmth were related to bad relationships with parents, absence of family support, harsh discipline, and lack of parental supervision.

CONCLUSIONS

The Spanish version of EMBU-C can be used with psychometric guarantees to identify rearing style in psychiatric outpatients because evidences of quality in this setting match those obtained in community samples.

Parent-child agreement in SCARED and its relationship to anxiety symptoms

The aim of this study is to analyze parent-child agreement in the Spanish version of the Screen for Anxiety Related Emotional Disorders and its relationship with the anxiety symptoms reported in a scheduled interview and the Mini-International Neuropsychiatric Interview for Children and Adolescents in order to establish the best informant and the degree of incremental validity when both sources of information are combined. Results indicated that, as in the original English version, parent-children agreement is low, with parents clearly tending to report fewer severe symptoms than children. When both parent and child versions were related to anxiety symptoms of the scheduled interview, children showed higher relationships than parents with all the anxiety categories reported by the scheduled interview. Children's scores were also the best predictors of anxiety symptoms, while incremental validity of parent's reports was quite low.
