Mother-Child Interactions and Externalizing Behavior Problems in Preschoolers over Time: Inhibitory Control as a Mediator
Clinical usefulness of the kiddie-disruptive behavior disorder schedule in the diagnosis of DBD and ADHD in preschool children
The aim of the present study was to investigate the clinical usefulness of a semi-structured diagnostic parent interview, i.e., the Kiddie-Disruptive Behavior Disorder Schedule (K-DBDS), in preschool children. For Oppositional Defiant Disorder (ODD), to define symptoms two coding methods were compared, i.e., one based on the threshold "often" and the other based on the frequency of behaviors in combination with the presence of clinical concern. For Attention-Deficit/Hyperactivity Disorder (ADHD), to define symptoms, two coding methods were compared, i.e., one with and one without consideration of pervasiveness across contexts. Participants were referred preschool children with externalizing behavioral problems (N?=?193; 83% male) and typically developing (TD) children (N?=?58; 71% male). The referred children were given a diagnosis of either ODD/CD (N?=?39), or ADHD (N?=?58) or comorbid ODD/CD+ADHD (N?=?57) or no diagnosis (N?=?39) based on best-estimate diagnosis. Receiver Operating Characteristic curve analyses showed that a cutoff score of four ODD symptoms using "often" as the threshold for frequency of behaviors led to a sensitivity of 87% and a specificity of 93%; the coding method which included the frequency of behaviors yielded a sensitivity of 56% and a specificity of 100%. For ADHD, a clinical cutoff score of five symptoms without the pervasiveness criterion yielded a sensitivity of 83% and a specificity of 98%; when the pervasiveness criterion was included sensitivity was 77% and specificity 98%. In the clinical assessment of ODD and ADHD in preschool children, the K-DBDS may be used with ODD symptom definition based on the threshold "often" and ADHD pervasiveness across contexts not included
Clinical usefulness of observational assessment in the diagnosis of DBD and ADHD in preschoolers
The aim of the present study was to investigate the clinical usefulness of an observational tool--the Disruptive Behavior Diagnostic Observation Schedule (DB-DOS)--in the diagnosis of disruptive behavior disorders (DBD) and attention deficit/hyperactivity disorder (ADHD) in preschoolers. We hypothesized that the DB-DOS may help support the presumption of a diagnosis generated by the information from parents and teachers (or other caregivers). Participants were referred preschool children with externalizing behavioral problems (N = 193; 83% male) and typically developing children (N = 58; 71% male). In view of the clinical validity study each child was given a diagnosis of either DBD (N = 40), or ADHD (N = 54) or comorbid (DBD + ADHD; N = 66) based on best-estimate diagnosis. The DB-DOS demonstrated good interrater and test-retest reliability for DBD and ADHD symptom scores. Confirmatory factor analysis demonstrated an excellent fit of the DB-DOS multidomain model of DBD symptom scores and a satisfactory fit of ADHD symptom scores. The DB-DOS demonstrated good convergent validity, moderate divergent validity, and good clinical validity on a diagnostic group level for DBD and ADHD symptom scores. The Receiver Operating Characteristic curve analyses revealed that for DBD the sensitivity and specificity are moderate and for ADHD good to excellent. The presumption of a diagnosis based on information from parents, teachers, and cognitive assessment was supported by the DB-DOS in 60% for DBD and 75% for ADHD. The DB-DOS can be used to help support a presumption of a DBD and/or ADHD diagnosis in preschool children
Mother-Child Interactions and Externalizing Behavior Problems in Preschoolers over Time: Inhibitory Control as a Mediator
Previous research has shown links between parenting and externalizing behavior problems in young children over time. Associations between inhibitory control, one of the executive functions, and externalizing behavior problems are widely established as well. Yet, the role of inhibitory control in the maintenance and change of externalizing behavior problems over time remains unclear. We examined whether inhibitory control could explain the link between mother-child interactions measured on a moment-to-moment timescale and preschoolers' externalizing behavior problems as reported by teachers. With a sample of 173 predominantly clinically referred preschoolers (76.9% boys) we tested a longitudinal model proposing that affective dyadic flexibility and maternal negative affect predict as well as interact in predicting hyperactive/impulsive behavior and aggressive behavior, with preschoolers' inhibitory control as a mediator. Our results provide support for this model for preschoolers' hyperactive/impulsive behavior, but not for aggressive behavior. Hence, inhibitory control is identified as a mechanism linking the content and structure of mother-child interactions to preschoolers' hyperactivity and impulsivity over time
