Sluggish Cognitive Tempo in Psychiatrically Hospitalized Children: Factor Structure and Relations to Internalizing Symptoms, Social Problems, and Observed Behavioral Dysregulation

As research examining sluggish cognitive tempo (SCT) advances, it is important to examine the structure and validity of SCT in a variety of samples, including samples of children who are clinically-distressed but not referred specifically for attention-deficit/hyperactivity disorder (ADHD). The present study used a large sample of psychiatrically hospitalized children (Nu2009=u2009680; 73xa0% male; 66xa0% African American) between the ages of 6 and 12 to examine the latent structure of SCT, ADHD, oppositional defiant disorder (ODD), depression, and anxiety using confirmatory factor analysis (CFA). Results of the CFA analyses demonstrated that SCT is distinct from these other dimensions of child psychopathology, including ADHD inattention, depression, and anxiety. Regression analyses indicated that SCT symptoms were positively associated with depression and, to a lesser degree, anxiety. SCT symptoms were also positively associated with children’s general social problems, whereas SCT symptoms were negatively associated with an observational measure of behavioral dysregulation (i.e., frequency of time-outs received as a part of a manualized behavior modification program). These associations were significant above and beyond relevant child demographic variables (i.e., age, sex, race), children’s other mental health symptoms (i.e., ADHD, ODD, depression, anxiety symptoms), and, for all relations except child anxiety, parents’ own anxiety and depression symptoms.

Aggression Among Children with ADHD, Anxiety, or Co-occurring Symptoms: Competing Exacerbation and Attenuation Hypotheses

Competing hypotheses for explaining the role of anxiety in the relation between attention-deficit/hyperactivity disorder (ADHD) symptoms and childhood aggression were evaluated. Two studies tested whether anxiety exacerbated, attenuated, or had no effect on the relation between ADHD and aggression subtypes among psychiatrically hospitalized children. In Study 1 (Nu2009=u200999), children who scored above clinical cut-off levels for anxiety only, ADHD only, and co-occurring ADHD and anxiety were compared on aggression subtypes (i.e., reactive, proactive, overt, and relational aggression). In Study 2, the moderating role of anxiety on the relation between ADHD and aggression subtypes was examined with a larger sample (Nu2009=u2009265) and with continuous variables. No support was found for either the attenuation or exacerbation hypothesis, and results remained consistent when separately examining hyperactivity/impulsivity and inattention symptoms of ADHD. Although ADHD symptoms were significantly associated with all aggression subtypes, this association did not remain when including symptoms of oppositional defiant disorder.

The role of cortisol in PTSD among women exposed to a trauma-related stressor

Research linking post-traumatic stress disorder (PTSD) to hypercortisolism in laboratory experiments was extended to a natural clinical setting. Mothers of children diagnosed with a life-threatening illness (N = 92) completed standardized measures of PTSD and provided a salivary cortisol sample during their childs medical check-up (Time 1) and again 24h later, after the threat of possible negative medical reports was removed (Time 2). Women who met diagnostic criteria for PTSD exhibited significantly higher cortisol levels at Time 1 compared to women who did not meet criteria for a diagnosis. No significant differences were observed for cortisol levels at Time 2 between the women with and without PTSD. These findings extend current laboratory findings linking hypercortisolism and PTSD to a natural, stressful situation. Implications for understanding the etiology of PTSD as well as for possible prevention and intervention options are discussed.

Sluggish cognitive tempo is associated with suicide risk in psychiatrically hospitalized children

BACKGROUNDnAlthough identified as a significant public health concern, few studies have examined correlates of suicide risk in school-aged children. Recent studies show a relation between sluggish cognitive tempo (SCT) symptoms and a range of adverse outcomes linked to suicidal ideation, including depression, emotion dysregulation, lowered self-esteem, and peer problems/social withdrawal, yet no study to date has examined SCT in relation to suicide risk.nnnMETHODSnWe tested the hypothesis that SCT would be associated with suicide risk in a sample of 95 psychiatrically hospitalized children (74% male; 62% black) between the ages of 8 and 12 (Mxa0=xa010.01, SDxa0=xa01.50). Parents completed measures of their childs psychiatric symptoms, including SCT and depression, as well as a measure of their own psychopathology. Children completed measures assessing loneliness and depression. Both parents and children completed measures of suicide risk.nnnRESULTSnWhite children reported greater suicide risk than nonwhite children. After controlling for demographic characteristics, loneliness, parental psychopathology, and correlated psychiatric symptoms, including both parent- and child self-reported depressive symptoms, SCT remained uniquely associated with childrens suicide risk. Results were consistent across both parent and child measures of suicide risk.nnnCONCLUSIONSnThis multi-informant study provides strong preliminary support for an association between SCT symptoms and suicide risk in psychiatrically hospitalized children, above and beyond loneliness, depression, and demographic characteristics. Findings are discussed in the context of the interpersonal theory of suicide. Additional studies are needed to replicate and extend these findings, with a particular need for studies that examine the cognitive processes and daydreaming content of individuals displaying elevated SCT symptomatology.

Oppositional Defiant Disorder Symptoms in Relation to Psychopathic Traits and Aggression Among Psychiatrically Hospitalized Children: ADHD Symptoms as a Potential Moderator

Oppositional defiant disorder (ODD) is associated with elevated rates of psychopathic traits and aggression. However, it remains unclear if attention-deficit/hyperactivity disorder (ADHD) symptoms exacerbate these relations, particularly in samples of children who are severely clinically distressed. The purpose of the present study was to test ADHD symptoms as a potential moderator of the relations of ODD symptoms to psychopathic traits (i.e., callous-unemotional [CU] traits, narcissism) and to aggressive subtypes (i.e., proactive, reactive aggression) in a large sample of children in an acute psychiatric inpatient facility (n = 699; ages 6-12). Multiple regression analyses indicated that, after controlling for child demographic variables, ADHD symptoms marginally exacerbated the relation between ODD symptoms and CU traits. Both ODD and ADHD symptoms had an additive, but not a multiplicative effect, in predicting narcissism. In addition, for a subset of the full sample for whom data were available (n =351), ADHD symptoms exacerbated the relation between ODD symptoms and both reactive and proactive aggression. These results suggest that ADHD symptoms tend to have a negative effect on the relation between ODD symptoms and markers of antisociality among children receiving acute psychiatric care.

The objective of this study is to examine the relation between parental coping style and the risk of parental and child posttraumatic stress symptoms (PTSS) among pediatric cancer survivors.

Child Routines and Parental Adjustment as Correlates of Internalizing and Externalizing Symptoms in Children Diagnosed with ADHD

Attention deficit hyperactivity disorder (ADHD) is one of the most common disorders of childhood, and the presence of comorbid externalizing and internalizing symptoms often result in severe negative long-term consequences. Multiple etiological factors contribute to the development of co-occurring symptoms. Family stability and consistency appear to be particularly important in effectively managing behavioral concerns. One important factor in producing consistency and stability is the use of routines. The current study examined how routines may be related to internalizing/externalizing symptoms in a clinical sample (Nxa0=xa0371) of children with ADHD (M agexa0=xa09.13, SDxa0=xa01.96; 77xa0% male). After controlling for child age, gender, and parental adjustment, routines predicted both internalizing and externalizing symptoms. Specific subtypes of routines including Household, Discipline, and Homework Routines were found to significantly predict symptomatology. A positive relation was found between parental and child adjustment problems; however, support for routines moderating the relation between parent and child adjustment was not supported.

The Role of Cortisol and Psychopathic Traits in Aggression Among At-Risk Girls: Tests of Mediating Hypotheses

Multiple etiological factors (e.g., biological and personality predispositions) have been linked to the development of aggression. The purpose of the present study was to examine the relation between proactive/reactive aggression and biological (HPA-axis functioning) and personality characteristics (subdimensions of psychopathy) among girls at risk for aggressive behavior. Participants included girls (Nu2009=u2009158) admitted for acute psychiatric inpatient treatment (M ageu2009=u20099.72; SDu2009=u20091.99). Parents completed a measure of proactive/reactive aggression and psychopathy upon admission. Fasting plasma cortisol levels were obtained the morning following the childs admission. Correlational analyses revealed a significant negative correlation between cortisol and the narcissism and impulsivity subdimensions of psychopathy as well as proactive/reactive aggression. A significant positive relation between proactive and reactive aggression and the three subdimensions of psychopathy was also observed. Path analyses revealed that only narcissism was uniquely and positively related to proactive and reactive aggression. Tests of indirect effects from cortisol to aggression through subdimensions of psychopathy indicated significant pathways via narcissism to proactive and reactive aggression. The findings support previous research linking narcissism uniquely to aggression for girls and suggest that the relation between cortisol and proactive/reactive aggression is mediated by narcissism.

Mediating Effect of Psychopathy on the Risk of Social Problems Among Children with ADHD Versus Sluggish Cognitive Tempo Symptoms

Sluggish cognitive tempo (SCT) has been proposed as a unique syndrome; however research examining how it is different from attention-deficit/hyperactivity disorder (ADHD) is just starting to emerge. The present study extends this research by examining how specific personality features (i.e., psychopathy) may mediate the relation between ADHD and social problems, but not between SCT and social problems. Caregivers of 198 children (6–12xa0years old) that presented for an inpatient psychiatric evaluation completed standardized measures of childhood behavior problems. Bootstrapped mediational analyses were performed to evaluate the mediating role of psychopathy on the relation between social problems and symptoms of ADHD versus SCT. Two sub-domains of psychopathy—impulsivity and narcissism—emerged as partial mediators for the relation between social problems and ADHD symptoms; whereas SCT symptoms were not found to be related to psychopathy after controlling for ADHD symptoms. These findings provide support for conceptualizing ADHD and SCT as discrete syndromes as well as for the mediating role of psychopathy domains on the risk of social problems among a clinical sample of youth with symptoms of ADHD.

The Role of Parenting Styles in the Relation Between Functions of Aggression and Internalizing Symptoms in a Child Psychiatric Inpatient Population

AbstractPsychiatric inpatient hospitalization is a costly intervention for youth. With rates of hospitalization rising, efforts to refine prevention and intervention are necessary. Aggression often precedes severe internalizing behaviors, and proactive and reactive functions of aggression are differentially associated with internalizing symptomatology. Thus, further understanding of the links between functions of aggression and internalizing symptomatology could aid in the improvement of interventions for hospitalized youth. The current study examined parenting styles, gender, and age as potential moderators of the relations between proactive and reactive aggression and internalizing symptoms. Participants included 392 children, 6–12xa0years of age admitted consecutively to a psychiatric inpatient unit. Reactive aggression was uniquely associated with anxiety symptoms. However, proactive aggression was associated with internalizing problems only when specific parenting styles and demographic factors were present. Although both proactive and reactive subtypes of aggression were associated with internalizing symptoms, differential associations were evident. Implications of findings are discussed.n
