“…Previous investigations (Peterson, 1961;Quay & Quay, 1965) suggested that a large portion of the systematic variance associated with maladaptive behavior inventories of children can be accounted for by two orthogonal dimensions: aggressive or conduct-deviant behavior and withdrawn or personality-deviant behavior.

“…This conceptual shift reflects a growing disagreement in the literature as to the core features underlying the syndrome. A number of authors have suggested that a continued emphasis on the hyperactivity aspect of the syndrome necessarily obscures diagnostically more relevant information, such as that relating to attention (Dykman et ai, 1971;Douglas etai, 1976;Douglas and Peters, 1979) or conduct problems (Quay and Quay, 1965;honey etai, 1978;Quay, 1979).…”

Evidence for an Independent Syndrome of Hyperactivity

It has recently been suggested that hyperactivity and an aggressive conduct disorder cannot exist independently in children. The results of a factor analysis of the Conners Teacher Rating Scales of over 9000 children provided preliminary evidence to the contrary; a hyperactivity factor emerged as explaining the greatest proportion of the variance. Because of the large size of our data-set, it was deemed necessary to investigate the heuristic value of this finding. Using norms calculated on composite factor scores, a contingency analysis was performed to determine the proportions of children who were above a two-standard deviation criterion of deviance on all factors and combinations of factors. The use of different degrees of statistical control produced prevalence estimates comparable to those reported in the literature. These findings raise the possibility that studies reporting different prevalences of hyperactivity may, in fact, be exercising different degrees of conservatism in classification. Also, when the extent of overlap along each of our factor dimensions was examined, a group of children who appeared to be hyperactive but not conduct-disordered emerged. These findings provide evidence for an independent syndrome of hyperactivity in a sample of Canadian children.

“…SCT symptoms involve daydreaming, feeling spacey, moving slowly, and processing information slowly, and have been posited to signal a potentially separate disorder (Barkley 2014; Bauermeister et al 2012; Lee et al 2014). Multiple factor analytic studies have supported an association between SCT and ADHD (Dumenci et al 2004; Quay 1983; Quay and Quay 1965; Willcutt et al 2012), but have indicated SCT symptoms do not represent another constituent symptom dimension of ADHD (Langberg et al 2014; McBurnett et al 2013). These findings have prompted researchers to call for SCT to be studied in its own right, apart from ADHD and other disorders (Becker et al 2016), even though the vast majority of work continues to examine SCTwithin the context of ADHD (Frick et al 1994).…”

Sluggish Cognitive Tempo Symptoms Contribute to Heterogeneity in Adult Attention-Deficit Hyperactivity Disorder

Attention-deficit hyperactivity disorder (ADHD) persists into adulthood in over 50% of cases, although its associated symptom profiles, comorbid problems, and neuropsychological deficits change substantially across development. Sluggish cognitive tempo (SCT) symptoms may contribute to associations between ADHD and comorbid problems and may partially explain the substantial heterogeneity observed in its correlates. 349 adults aged 18–38 years (M = 23.2, SD = 4.5, 54.7% male, 61.03% with ADHD) completed a multi-informant diagnostic procedure and a comprehensive neuropsychological battery. Adults with ADHD (n = 213) were retained for analyses. Latent class analyses (LCA) revealed three profiles of SCT symptoms among those with ADHD, which we classified as minimal, moderate, or severe SCT. Multiple analysis of covariance (MANCOVA) revealed significant differences among these profiles, which remained when controlling for persistence of ADHD symptoms and sex. In general, adults with ADHD combined with SCT symptoms (moderate and severe) had significantly more symptoms of anxiety, depression, and persistent inattention, and had more severe professional and relational impairment compared to ADHD adults without SCT. Compared to those with moderate or minimal SCT symptoms, the severe SCT group had the most symptoms of depression and internalizing disorders, and the most impairment in the domain of daily responsibility. No significant differences based on externalizing symptoms emerged when controlling for sex and persistence of inattention symptoms, suggesting the moderate and severe SCT groups do not simply reflect more symptoms. Moreover, follow-up mediation analyses revealed that SCT might at least partially explain the heterogeneity in ADHD. Findings have implications for refinement of etiological conceptualization, assessment methods, and intervention strategies.
