摘要：Increased understanding of early neurobehavioural development is needed to prevent, identify, and treat childhood psychopathology most effectively at the earliest possible stage. Prospective birth cohorts can elucidate the association of genes, environment, and their interactions with neurobehavioural development. We conducted a systematic review of the birth cohort literature. On the basis of internet searches and 6,248 peer-reviewed references, 105 longitudinal epidemiological studies were identified. Twenty studies met inclusion criteria (prospectively recruited, population-based cohort studies, including at least one assessment before the end of the perinatal period and at least one assessment of behaviour, temperament/personality, neuropsychiatric or psychiatric status before 19 years of age), and their methodologies were reviewed in full. Whilst the birth cohort studies did examine some aspects of behaviour and neurodevelopment, observations in the early months and years were rare. Furthermore, aspects of sampling method, sample size, data collection, design, and breadth and depth of measurement in some studies made research questions about neurodevelopment difficult to answer. Existing birth cohort studies have yielded limited information on how pre- and perinatal factors and early neurodevelopment relate to child psychopathology. Further epidemiological research is required with a specific focus on early neurodevelopment. Studies are needed which include the measures of early childhood psychopathology and involve long-term follow-up.

摘要：The main aim of this study was to examine the moderating effects of attention deficit hyperactivity disorder (ADHD) on anxiety disorders in children. Data were analyzed from a large referred sample of children with anxiety disorder without comorbid ADHD (anxiety disorder, N = 253), anxiety disorder plus comorbid ADHD (anxiety disorder + ADHD, N = 704), and ADHD without comorbid anxiety disorder (ADHD, N = 511). Children were comprehensively assessed, including by structured diagnostic interview (K-SADS-E). Overall rates of individual anxiety disorders, as well as age of onset and severity of illness were not significantly different in the presence of comorbid ADHD. School functioning in children with anxiety disorders was negatively impacted by the presence of comorbid ADHD. Frequency of mental health treatment in children with anxiety disorders was significantly increased in the presence of comorbid ADHD. ADHD had a limited impact on the manifestation of anxiety disorder in children suggesting that ADHD and anxiety disorders are independently expressed.

摘要：The objectives of the study are (i) to describe and compare the epidemiology of emotional/behavioral problems and associated risk/protective factors among nationally representative samples of institutionally reared and similarly aged community-based adolescents brought up in their natural homes by means of youth self-reports, caregiver/parent, and teacher informants; and (ii) to identify mental health service needs and utilization. A cross-sectional survey was conducted between November 2005 through April 2006 using an equal probability cluster sample of 11-18 year old adolescents in institutional care settings (N = 350; 163 males, 187 females) and results were compared with similarly aged community sample of youth living in their natural homes (N = 2,206). The Sociodemographic Information Form, Youth Self Report (YSR), Child Behavior Checklist (CBCL) by caregivers for institutional sample and parents for the community sample, and Teacher's Report Form (TRF) were used to obtain standardized data on demographic characteristics, emotional/behavioral problems, and risk/protective factors. The prevalence of problems behaviors by YSR, caregiver/parent CBCL, and TRF were: 47, 15.1, 20.5% for the institutional versus 10.1, 7.5 and, 9.5% for the community samples, respectively (p < 0.05). Youth self-reports were fourfold, and all informant reports were twofold higher for institutional versus community comparisons. Furthermore, institutional sample had consistently higher rates, not only of Externalizing, but Internalizing, Social Problems, Attention Problems, and Thought Problems, as well as discrete DSM-oriented scales, suggesting that labeling of institutional youth as simply aggressive and delinquent contributes to their further marginalization and does not comprehensively address their mental health needs. In terms of protective factors, we found that: perceived social support, high competency scores, supportive caregiving, getting along well with peers and relatives (positive relationships), and problem solving skills were significantly protective of mental health. On the other hand fatalistic beliefs, cigarette and alcohol use were significantly associated with increased risk for problem behaviors (p < 0.05). The primary reason for institutional placement was family disruption (68.9%), poverty (15.7%), abandonment (8.4%), and physical or sexual abuse (5.4%). Only 31.2% of the youth were in fact true orphans (loss of one or both parents). It is therefore remarkable that in terms of service use, despite consistently high prevalence of problem behaviors across all informant sources, only 2.4% of the youth had received any speciality mental health services during institutional care. In conclusion, there is a pressing need to transform the social and health care policy and to provide family and community-based alternatives for youth currently in institutional care in Turkey. Before this goal is achieved, it is necessary to address their mental health needs urgently and comprehensively. The highest rates of problems by youth self-report also support the view that the youths' own voices ought to be heard and need to inform the reform process regarding their future care.

摘要：The Marmara earthquakes occurred in the Marmara Region (North West) of Turkey in 1999 and resulted in a death toll of approximately 20,000. This paper investigates the relationships between diagnoses and certain variables in children who developed emotional and/or behavioral disturbances in the aftermath of the Marmara earthquakes and were subsequently seen at a child psychiatry outpatient clinic. The variables evaluated are gender, age, the location where the earthquake was experienced, and the degree of losses, bodily injuries, and damage to the residence. Medical records of 321 children and adolescents ranging in age from 2 to 15 years who presented at the clinic due to problems associated with the earthquake between August 1999 and February 2000 were reviewed. Of the patients, 25.5% were diagnosed with post-traumatic stress disorder (PTSD), 16.5% with acute stress disorder (ASD) and 38% with adjustment disorder. No relationship is found between gender and diagnosis. Younger age groups tended to be diagnosed with adjustment disorder. Those who had lost relatives, friends or neighbors were more frequently diagnosed with ASD or PTSD. The same was true for children whose residence was heavily damaged. Children and adolescents constitute the age group that is most severely affected by natural disasters and display significant emotional-behavioral disturbances. The frequency of ASD and PTSD found in our study is considerably high. Although rarely mentioned in the literature, adjustment disorder appears to be one of the most common reactions of children to trauma.
