Academic pathways between attention problems and depressive symptoms among urban African American children.

The present study investigated the pathways between attention problems and depressive symptoms, particularly the role of academic incompetence, among a community sample of urban African American children. Results supported the hypothesized path models from inattention to depressive symptoms for girls and boys. Academic performance in the spring of first grade mediated the relationship between inattention in fall of first grade and depressive symptoms in spring of 3rd grade. The effects held when controlling for conduct problems and academic competence in first grade suggesting the path was specific to attention problems rather than a more general externalizing or school readiness pathway. Implications for designing interventions and prevention strategies for children with attention problems and depressive symptoms are discussed.

The family environment and developmental psychopathology: the unique and interactive effects of depression, attention, and conduct problems.

Prior studies have found remarkable similarity in the family characteristics across a wide range of child psychopathologies. This study investigated the unique relationships between symptoms of depression, conduct problems/aggression, and inattention/hyperactivity and characteristics of the family environment. Parents and teachers completed multiple behavioral, emotional, and family measures to describe the characteristics of a community sample of 362 children. Results indicated that depression and conduct problems/aggression symptoms were uniquely associated with specific family environments. Both symptom clusters predicted family environments marked by less cohesiveness and intellectual/cultural pursuits and greater conflict. Depression alone was related to less expressiveness, independence, and activity, and to higher levels of control. Inattention/hyperactivity was not uniquely related to any aspect of family environment when controlling for depression and conduct/aggression problems, nor were combinations of symptoms. Findings are discussed with regard to implications for understanding clinical presentations, comorbidity, and treatment.

Attention Deficit Disorder with Hyperactivity↗

Attention deficit-hyperactivity disorder, depression, and self- and other-assessments of social competence: a developmental study.

This study examined whether others (i.e., teachers and parents) and self-appraisals of social competence mediated the relationship between Attention-Deficit/Hyperactivity Disorder (ADHD) and depression. To determine whether age moderated the effects of the mediation, the total sample was divided into younger (under 9) and older (at or above 9 years) age levels. The total sample (age range 6.6 to 11.7 years) was primarily male (194 boys and 52 females) and consisted of 148 children diagnosed with ADHD and 98 community controls. Three central findings were derived from this study. First, there was a strong relationship between ADHD (with and without comorbid ODD/CD) and depression in both younger and older aged children. Among younger children with ADHD, there was no differential influence on the level of depression depending on whether or not ADHD was comorbid with ODD/CD; in contrast, with older children, comorbid ODD/CD had higher levels of depression than was the case for children with ADHD that did not display such comorbidity. Second, with younger children approximately half of the relationship between ADHD (with and without comorbid ODD/CD) and depression was exclusively mediated by others appraisal of social competence. Third, a more complex relationship between ADHD and depression emerged during the later part of the childhood years. As such, the relationship between ADHD, others appraisals of social competence, and depression was further mediated by self-appraisals of social competence. Findings are discussed in terms of developmental theory and theoretical models of childhood depression.

Potential cognitive, parenting, and developmental mediators of the relationship between ADHD and depression.

The authors investigated the role of parent behavior management and locus of control in mediating the relationships between ADHD (attention-deficit/hyperactivity disorder) and depression in a community sample of 232 children with ADHD and 130 community controls. Results supported the hypothesized path models to depression for older and younger subjects. For older subjects (10 years and older), a cognitive variable, locus of control, partially mediated the relationships between ADHD and parent management and depression. In addition, parent management partially mediated the relationships of ADHD with locus of control and depression. For the younger group (under 8 years old), however, locus of control did not mediate the effects of parent management and ADHD on depression. Consistent with developmental theories, only an environment variable, parent management, explained the relationship between ADHD and depression for this younger group. For children 8-9 years old, both locus of control and parent management partially mediated the ADHD-depression relationship; however, similar to the younger children, locus of control did not mediate the parent management-depression relationships. Implications for designing interventions and prevention strategies for children with ADHD are discussed.

Children with ADHD and depression: a multisource, multimethod assessment of clinical, social, and academic functioning.

Although ADHD and depression are common comorbidities in youth, few studies have examined this particular clinical presentation. To address method bias limitations of previous research, this study uses multiple informants to compare the academic, social, and clinical functioning of children with ADHD, children with ADHD and depression, and children without ADHD, all derived from a large community sample. High levels of comorbid depression are found in children with ADHD. Children withADHDand depression are more depressed and anxious than their non-depressed ADHDcounterparts but do not have more extreme levels of ADHD or aggression. The association between depression and ADHD does not appear to be epiphenomenal, that is, related to a shared association with anxiety or externalizing symptoms. Finally, children with ADHD and depression display more impairment in social and academic functioning compared to controls. Although social impairment is greater in children with ADHD and depression than in children with only ADHD, conduct problems are not.

Diagnosing attention deficit disorders with the Behavioral Assessment System for Children and the Child Behavior Checklist: test and construct validity analyses using optimal discriminant classification trees.

The usefulness of the Behavioral Assessment System for Children (BASC) and Child Behavior Checklist (CBCL) Parent scales was examined with respect to (a) differentiating students with attention deficit-hyperactivity disorder (ADHD) from non-ADHD students and (b) discriminating between the predominantly inattentive-type and combined-type ADHD-afflicted students. For both the BASC and the CBCL, a different optimal discriminant classification tree analysis (CTA) model was developed for each of the 2 diagnostic predictions. For distinguishing ADHD students from non-ADHD students, the BASC model was more parsimonious and accurate than the CBCL model. Toward the goal of differentiating between primarily inattentive and combined types, the CBCL's model was superior for predicting primarily inattentive students. The results demonstrate the diagnostic utility of the BASC and CBCL and describe salient behavioral dimensions associated with subtypes of ADHD.

Attention deficit hyperactivity disorder: an epidemiological screening method.

Multistage identification, an epidemiological screening method of diagnostic assessment, was used to identify attention-deficit hyperactivity disorder (ADHD) in 1,490 elementary-school students. Children diagnosed with ADHD exhibited more impairment on adjustment measures and were more likely to have coexisting disruptive behavior disorders than were children diagnosed as subclinical non-ADHD.
