    EMOTION REGULATION MEDIATES THE RELATIONSHIP BETWEEN ADHD AND DEPRESSIVE SYMPTOMS IN YOUTH
    (2010) Seymour, Karen E.; Chronis-Tuscano, Andrea M.; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    A significant body of longitudinal research suggests increased rates of mood disorders as well as depressive symptoms in youth diagnosed with attention deficit/ hyperactivity disorder (ADHD) in contrast to non-ADHD comparison youth. Furthermore, individuals with co-occurring ADHD and mood disorders experience more serious impairments and worse outcomes than those with either disorder alone. However, few studies have examined the underlying mechanisms which may better elucidate the relationship between ADHD and depression in youth. The present study examined emotion regulation as a mediator in the relationship between ADHD and depressive symptoms in youth. Moreover, effortful control was examined as a mediator in the relationship between ADHD and emotion regulation. Participants included 69 youth between the ages of 10 and 14 with (n = 37) and without (n = 32) DSM-IV ADHD. Parent and youth ratings of depressive symptoms and emotion regulation were collected, and youth completed computerized measures of effortful control. Results demonstrated significant differences between youth with and without ADHD on depressive symptoms and emotion regulation ability, but not effortful control. Furthermore, emotion regulation fully mediated the relationship between ADHD and depressive symptoms. Clinical implications and limitations are discussed.

    The association between child gender and observed maternal responsiveness in mothers of children with attention-deficit/hyperactivity disorder
    (2007-04-19) Seymour, Karen E.; Chronis, Andrea M.; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The present study examined the relationship between child gender and observed maternal responsiveness in mothers of 6-10 year old children with ADHD. Fifty-seven mother-child dyads participated in a 25-minute observed parent-child interaction comprised of both structured and unstructured tasks. Observed interactions were coded for overall and dimensional categories of maternal responsiveness. Results indicated that mothers of boys and mothers of girls with ADHD did not differ on either overall levels of responsiveness or individual dimensions of responsiveness (e.g., control, affect, etc.). However, responsiveness did vary as a function of child age and maternal race/ethnicity, with mothers of younger children and Caucasian mothers displaying higher levels of responsiveness. Implications and future directions are discussed.
