Callous Unemotional (CU) traits are associated with different environmental risk factors, such as negative stressful life events (SLE). The most common studied SLE associated with CU trait has been childhood maltreatment, but less is known about how other SLE impact the development of CU traits. Therefore, this work examines risk factors, personal factors (executive functioning), and mental health outcomes associated with the trajectories of Callous Unemotional (CU) traits and Stressful Life Events (SLE) in a community sample of children. A cohort of 377 preschoolers were followed up between ages 3 and 10. Several risk factors and outcomes for three trajectory groups (high CU/SLE; high CU/low SLE; and the reference group with low CU/SLE) were analyzed by using multiple post-hoc comparisons. We hypothesized that children with high CU/SLE would face more contextual risk factors, more executive functioning difficulties and more mental health problems than children with high CU/low SLE or the reference group. At the age of 3, children who showed high CU/SLE faced more early contextual adversity, including socioeconomic difficulties and maternal antisocial behavior than the other groups of children. At the age of 10, children with high CU/SLE presented more peer problems and higher psychopathology symptoms than the reference group, but no differences on mental health outcomes in comparison to the high CU/low SLE group. These results have potential implications for clinical practice and studies attempting to identify different CU subtypes in children.

The Achenbach System of Empirically Based Assessment (ASEBA) is an example of the efforts to integrate categorical and dimensional assessment methods. The latest editions of the Child Behavior Checklist (CBCL) and the Youth Self-Report (YSR) included the DSM-Oriented Scales, constructed in rational manner based on the items making up these inventories. Objective: To analyze the psychometric properties of the DSM-Oriented Scales of the CBCL and YSR. Method: A clinical sample of 420 children and adolescents (aged 8-17 years) was assessed with the CBCL and YSR, with a structured diagnostic interview and with measures of functional impairment to study the reliability and validity of the DSM-Oriented Scales. Results: Internal consistency ranged from moderate to good for all the scales except the DSM-Anxiety Problems Scale. Agreement between parents and children ranged between moderate and low values. Kappa coefficients showed moderate agreement in the different symptoms. The DSM-Oriented Scales presented acceptable diagnostic power for DSM-IV disorders and a significant relationship with measures of functional impairment. Conclusion: The DSM-Oriented Scales constitute a useful approach from the dimensional model to the DSM-IV disorders in Spanish clinical population.

Reported one-year prevalence of service use due to mental disorders in children and adolescents from the general population varies according to country, organization of services, and services considered. Among factors associated with use of services, the literature lists parental and school personnel's perception of problems, having a psychiatric diagnosis (especially externalizing), symptom severity, comorbid disorders, functional impairment, family burden, family environment or being a boy (Cabiya et al., 2006; Farmer et al., 2003; Sayal, 2004). A better understanding of these factors may help to optimize access to services of children needing help.

The goal of the study was to ascertain the factor structure and prevalence of psychiatric disability in children and adolescents in relation to demographic variables and diagnosis. A representative sample of 1420 children (9–13 years) from 11 countries in North Carolina was followed for up to 6 years. Children and caretakers were interviewed with the Child and Adolescent Psychiatric Assessment, which generates DSM-IV diagnoses and includes a measure of disability secondary to psychological symptoms. Three broad areas of disability were identified (relating to family, school, and peers). School disabilities were more common in boys than girls, while the reverse was true of family disability. Effects of age were complex, and partially gender-differentiated. Children from minority ethnic groups had a higher overall prevalence of school disabilities, and were more prone than Whites to the disabling effects of disruptive behavior disorders. Anxiety disorders were as likely to result in disability as depressive disorders, and oppositional defiant disorders were more strongly associated with disability in some areas than was conduct disorder. The areas where disability is manifested are different depending on race, gender, age, and the type of disorder suffered. The implications of these findings for nosology and prevention are discussed.

The goal of this study was to investigate the variables that best predict functional impairment in children and adolescents. Two hundred and eight psychiatric and 129 pediatric children aged 7 to 17 years were assessed with measures of psychopathology, functional impairment, temperament, marital discord, educational style, coping, developmental milestones, stressful life events, medical history, school information, and family history of psychopathology. Multiple regression models adjusted by psychopathology were estimated. The global model, which included all the significant variables in partial models, revealed the following predictors of impairment: receiving review lessons, chronic disease or handicap, the presence of problems the child interpreted as stressful, late onset and long duration of psychopathological problems. These indicators could be useful for the proper identification of children with severe difficulties, in order to provide them with adequate psychological services.

This paper reviews some of the characteristics of the informants as well as some of the attributes of the DICA-R interview that could influence the test–retest reliability in a sample of 109 psychiatric outpatients aged 7–17 years. Different regression models using reliability coefficients constructed from the kappa statistic were obtained. Of those characteristics evaluated in the children, a high level of psychological impairment proved to be significant when it came to predicting the lowest test–retest reliability of the answers; none of the subject-related characteristics were significant in the adolescent patient model. The attributes of the questions that proved to be significant when explaining the lower reliability obtained for the individual question in the children's model were the length of the questions (longest questions), the content (internalising), the presence of time concepts, comparison with the peer group, and the need to exercise judgement; in the adolescents' model, the significant attributes were found to be the internalising content, the presence of time concepts, evaluation concerning the impairment caused by the disorder, and the need to exercise judgement. In the group of children our results are in accordance with the original paper. Similar results were found with adolescents. These findings have implications for the development and revision of new interview schedules.
