Issues in the Diagnosis of Attention Deficit Disorder: A Cautionary Note on the Gordon Diagnostic System

In a recent paper Gordon (1986) has compared the strengths and weaknesses of traditional microcomputer-based assessment of attention deficit disorder (ADD) with those offered by the Gordon Diagnostic System (GDS; Gordon & McClure 1983; 1984). Not surprisingly, although careful not to overstate the case, he finds GDS to be an improvement over the use of standard microcomputers. Nevertheless, several of his criticisms of microcomputers seem forced, and he tends to downplay some of the more serious concerns associated with the GDS. Given that the GDS is receiving widespread attention, with nationwide marketing procedures underway, it seems fitting to examine its strengths and weaknesses independently as compared to more traditional methods of assessment of attention deficit disorder. To facilitate this goal the history of the GDS will be reviewed since in its relatively brief life several important events have already occurred

Dynamic treatment regimes: Technical challenges and applications

Dynamic treatment regimes are of growing interest across the clinical sciences because these regimes provide one way to operationalize and thus inform sequential personalized clinical decision making. Formally, a dynamic treatment regime is a sequence of decision rules, one per stage of clinical intervention. Each decision rule maps up-to-date patient information to a recommended treatment. We briefly review a variety of approaches for using data to construct the decision rules. We then review a critical inferential challenge that results from nonregularity, which often arises in this area. In particular, nonregularity arises in inference for parameters in the optimal dynamic treatment regime; the asymptotic, limiting, distribution of estimators are sensitive to local perturbations. We propose and evaluate a locally consistent Adaptive Confidence Interval (ACI) for the parameters of the optimal dynamic treatment regime. We use data from the Adaptive Pharmacological and Behavioral Treatments for Children with ADHD Trial as an illustrative example. We conclude by highlighting and discussing emerging theoretical problems in this area

Discriminating Between Children With ADHD and Classmates Using Peer Variables

Objective: Impaired peer relationships have long been recognized as one of the major functional problems of children with ADHD, but no specific guidelines on clinical levels of impairment in this domain exist. Method: This study used Receiver Operating Characteristics methodology to determine what aspects of peer functioning best discriminate between children with ADHD and their classmates. Optimal cutoffs indicative of clinical levels of impairment associated with ADHD diagnosis were determined for all variables. The participants were 165 children with AD/HD who were part of the Multimodal Treatment Study of Children With ADHD and their 1,298 classmates. Results: Variables that best discriminated between children with ADHD and their classmates included peer rejection and negative imbalance between given and received liking ratings (i.e., children with ADHD liked others more than they were liked). Conclusion: Peer rejection and negative imbalance show most promise for identifying clinically significant levels of peer relationship impairment in children with ADHD. (J. of Att.

Behavior Therapy and Callous-Unemotional Traits: Effects of a Pilot Study Examining Modified Behavioral Contingencies on Child Behavior

The conduct problems of children with callous-unemotional traits (i.e., lack of empathy, guilt/lack of caring behaviors) (CU) are particularly resistant to current behavioral interventions, and it is possible that differential sensitivities to punishment and reward may underlie this resistance. Children with conduct problems and CU (CPCU) are less responsive to behavioral punishment techniques (e.g., time-out), however reward techniques (e.g., earning points for prizes or activities) are effective for reducing conduct problems. This study examined the efficacy of modified behavioral interventions, which de-emphasized punishment (condition B) and emphasized reward techniques (condition C), compared to a standard behavioral intervention (condition A). Interventions were delivered through a Summer Treatment Program over seven weeks with an A-B-A-C-A-BC-A design to a group of eleven children (7–11 years; 91% male). All children were diagnosed with either oppositional defiant disorder or conduct disorder, in addition to attention-deficit/hyperactivity disorder. Results revealed the best treatment response occurred during the low punishment condition, with rates of negative behavior (e.g., aggression, teasing, stealing) increasing over the seven weeks. However, there was substantial individual variability in treatment response, and several children demonstrated improvement during the modified intervention conditions. Future research is necessary to disentangle treatment effects from order effects, and implications of group treatment of CPCU children (i.e., deviancy training) are discussed

Coping Skills and Parent Support Mediate the Association Between Childhood Attention-Deficit/Hyperactivity Disorder and Adolescent Cigarette Use

Child and Parent Predictors of Perceptions of Parent–Child Relationship Quality

Objective/Method: Predictors of perceptions of parent–child relationship quality were examined for 175 children with ADHD, 119 comparison children, and parents of these children, drawn from the follow-up phase of the Multimodal Treatment Study of Children with ADHD. Results/Conclusion: Children with ADHD perceived their mothers and fathers as more power assertive than comparison children. Children higher on depressive symptomatology also perceived their mothers and fathers as less warm and more power assertive. Mothers perceived themselves as more power assertive and fathers perceived themselves as less warm if they were higher on depressive symptomatology themselves or had children with ADHD or higher levels of depressive symptomatology. Several interactions indicated that the association between child factors and parental perceptions of warmth and power assertion often depended on parental depressive symptomatology. The findings resolve a previous contradiction in the literature regarding the relationship between child depressive symptoms and parental perceptions of parent–child relationship quality

Parent Agreement on Ratings of Children's Attention Deficit/Hyperactivity Disorder and Broadband Externalizing Behaviors

Mothers and fathers often disagree in their ratings of child behavior, as evidenced clinically and as supported by a substantial literature examining parental agreement on broadband rating scales. The present study examined mother-father agreement on Diagnostic and Statistical Manual-based symptom-specific ratings of Attention-Deficit/Hyperactivity Disorder (ADHD), as compared to agreement on broadband ratings of externalizing behavior. Based on mother and father ratings of 324 children who participated in the Multimodal Treatment Study of Children with ADHD (MTA), parental agreement was computed and patterns of disagreement examined. Mother-father ratings were significantly correlated; however, a clear pattern of higher ratings by mothers was present. Agreement on attention-deficit/hyperactivity disorder symptom-specific ratings was significantly lower than that for broadband externalizing behaviors and oppositional defiant disorder symptoms. Of several moderator variables tested, parental stress was the only one that predicted the discrepancy in ratings. Disagreement between parents is clinically significant and may pose complications to the diagnostic process

Hispanic/Latinx ethnic differences in the relationships between behavioral inhibition, anxiety, and substance use in youth from the ABCD cohort

IntroductionElevated levels of behavioral inhibition (BI) may connote risk for both anxiety and substance use disorders. BI has consistently been shown to be associated with increased levels of anxiety, while the association between BI and substance use has been mixed. It is possible that the relationship between BI and substance use varies by individual difference factors. Hispanic/Latinx (H/L) youth in particular may have stronger relationships between BI, anxiety, and substance use.MethodsThe present study therefore evaluated (1) the prospective relationships between BI [assessed via self-reported behavioral inhibition system (BIS) scale scores], anxiety, and substance use in youth (n = 11,876) across baseline, 1-, and 2-year follow-ups of the Adolescent Brain Cognitive Development (ABCD) Study (ages 9–12) and (2) whether these relationships differed by H/L ethnicity while covarying for average behavioral approach system scores, race, sex, age, highest parental income, highest parental education, and past-year substance use (for analyses involving substance use outcomes).ResultsBaseline levels of BIS scores predicted increased anxiety symptoms at both 1- and 2-year follow-ups and did not differ by H/L ethnicity. Baseline levels of BIS scores also prospectively predicted increased likelihood of substance use at 2-year follow-up, but only for H/L youth and not at 1-year follow-up.DiscussionHigh scores on the BIS scale contribute risk to anxiety across ethnicities and may uniquely contribute to risk for substance use in H/L youth

Childhood ADHD and Growth in Adolescent Alcohol Use: The Roles of Functional Impairments, ADHD Symptom Persistence, and Parental Knowledge

Research on the relation between childhood Attention-Deficit/Hyperactivity Disorder (ADHD) and adolescent alcohol use has found mixed results. Studies are needed that operationalize alcohol use in developmentally appropriate ways and that test theoretically plausible moderators and mediators in a longitudinal framework. The current study tested childhood ADHD as a predictor of alcohol use frequency at age 17, and age-related increases in alcohol use frequency, through adolescence for 163 adolescents with ADHD diagnosed in childhood and 120 adolescents without ADHD histories. Childhood ADHD did not predict either alcohol outcome. However, parental knowledge of the teen’s friendships, activities, and whereabouts moderated the association such that childhood ADHD predicted alcohol use frequency at age 17 when parental knowledge was below median levels for the sample. Mediational pathways that explained this risk included social impairment, persistence of ADHD symptoms, grade point average, and delinquency. Social impairment was positively associated with alcohol use frequency through delinquency; it was negatively associated with alcohol use frequency as a direct effect independent of delinquency. These nuanced moderated-mediation findings help to explain previously inconsistent results for the ADHD-adolescent alcohol use association. The findings also imply that future research and intervention efforts should focus on ADHD-related social and academic impairments as well as symptom persistence and parenting efforts
