Co-occurring weight problems among children with attention deficit/hyperactivity disorder: the role of executive functioning

OBJECTIVE:To explore the link between pediatric obesity and attention deficit/hyperactivity disorder (ADHD) by examining whether executive functioning (EF) and medication status are associated with body mass index (BMI) and weight status in children with ADHD.METHOD:Participants for this study included 80 children (mean age=10 years, 9 months) with a DSM-IV diagnosis of ADHD, confirmed by a comprehensive clinical diagnostic assessment. Childrens EF was measured using three neuropsychological tests, and severity of ADHD symptoms and medication status were obtained from parent report. Childrens height and weight were also measured during the visit using a wall-mounted stadiometer and a balance beam scale.RESULTS:Children with ADHD who performed poorly on the neuropsychological battery had greater BMI z-scores, and were more likely to be classified as overweight/obese compared with children with ADHD who performed better on the neuropsychological battery. In addition, children with ADHD who were taking a stimulant medication had significantly lower BMI z-scores compared with children with ADHD who were not taking medication or who were taking a non-stimulant medication.CONCLUSION:EF is more impaired among children with ADHD and co-occurring weight problems, highlighting the importance of self-regulation as a link between pediatric obesity and ADHD.

ADHD symptomatology and risky health, driving, and financial behaviors in college: the mediating role of sensation seeking and effortful control

Objective: To examine the extent to which effortful control (EC) and sensation seeking (SS) tendencies explain the association between the severity of ADHD symptoms and risky behaviors. Method: Participants included 555 college students (66% females) who completed self-report measures assessing their ADHD symptoms, EC abilities, SS tendencies, and risky health (e.g., substance use) and driving/financial behaviors (e.g., misuse of credit cards). Results: Severity of college students’ ADHD symptoms, EC abilities, and SS tendencies were related to all risky behaviors. Multiple mediational analyses further indicated that students’ SS tendencies significantly mediated the association between ADHD symptoms and the risky health factor but not the risky driving/financial factor. EC, however, significantly mediated the association between ADHD symptoms and both the risky health and driving/financial factors. Conclusion: The current study provides initial data showing potentially different mechanisms that explain the link between college students’ severity of ADHD symptoms and risky behaviors.

Differentiating co-occurring behavior problems in children with ADHD: patterns of emotional reactivity and executive functioning.

Objective: This study examined whether “top-down” and “bottom-up” control processes can differentiate children with ADHD who exhibit co-occurring aggression and/or internalizing symptoms. Method: Participants included 74 children (M age = 10.7 years) with a Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) diagnosis of ADHD. The authors’ top-down measure was executive functioning (EF) indexed via two neuropsychological tasks whereas their bottom-up measure was emotional reactivity. Parents also reported on children’s aggression and internalizing symptoms. Results: Emotional reactivity was associated with co-occurring aggressive symptoms, regardless of the presence of internalizing symptoms or ADHD symptom severity, whereas EF deficits were less likely to occur in children with ADHD and co-occurring internalizing symptoms. Conclusion: The authors’ findings highlight the importance of integrating top-down and bottom-up regulatory measures when studying the multipathway conception of ADHD and its co-occurring problems.

The diabetes online community: the importance of forum use in parents of children with type 1 diabetes

Online forums for chronic health conditions emerged as early as 30 yr ago and interest in their study has blossomed. Type 1 diabetes (T1D) forums have grown exponentially since 2005. Therefore, a comprehensive evaluation of these forums is needed. This study assesses the demographics and motivations of parents who use type 1 diabetes forums and the potential impact that forum membership (FM) has on parenting stress and hypoglycemic fear. One hundred and two parents were recruited through online T1D forums and asked to complete qualitative and quantitative measures of their experience with the T1D forums. Results of this study suggest that parents who use T1D forums mirror those who participate in clinic‐based research protocols and are primarily motivated to participate in forums to increase their diabetes knowledge and gain social support. Indeed, parents who use T1D forums report high levels of trust, social support, and perceived knowledge gained. However, FM was positively related to increased self‐reported parenting stress frequency and hypoglycemic fear behaviors. Taken together, the relationships formed within these communities may have a significant impact on the experience of these caregivers. The need for future research and potential implications for physicians, including parent debriefing, are discussed.

Validation of a classification system of obsessive–compulsive spectrum disorder symptoms in a non-clinical sample

Controversy surrounds the classification of obsessive-compulsive spectrum disorder (OCSD) symptoms. In this study, we tested whether a broad OCSD symptoms model consisting of obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, pathological skin picking, impulsivity, and anxiety symptoms displayed sufficient data fit. Alternatively, we tested whether a reduced OCSD symptoms model consisting of obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, and pathological skin picking symptoms demonstrated superior fit. The reduced OCSD symptoms model demonstrated good data fit. However, the broader OCSD symptoms model only displayed marginal data fit. In context with other findings, results of this study support an OCSD symptoms dimension that includes obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, and pathological skin picking symptoms. Implications of these findings are discussed as they relate to proposed changes in the forthcoming edition of the Diagnostic and Statistical Manual.

Telehealth interventions to reduce management complications in type 1 diabetes: A review.

Type 1 diabetes is a chronic illness with a high burden of care. While effective interventions and recommendations for diabetes care exist, the intensive nature of diabetes management makes compliance difficult. This is especially true in children and adolescents as they have unique psychosocial and diabetes needs. Despite the development of effective in-person interventions targeting improving self-management and ameliorating psychosocial difficulties there are still a number of barriers to implementing these interventions, namely time, cost, and access. Telehealth interventions allow for the dissemination of these interventions to a broader audience. Self-management and psychosocial telehealth interventions are reviewed with a special emphasis on mobile phone and internet based technology use. While efficacy has been demonstrated in a number of telehealth interventions with improved cost effectiveness over in-person interventions, many challenges remain including high participant attrition and difficulties with receiving reimbursement for services rendered. These and other challenges are discussed with recommendations for researchers and telehealth providers provided.

Psychometric properties of the Treatment-Emergent Activation and Suicidality Assessment Profile (TEASAP) in youth with OCD

This study evaluated the psychometric properties of the treatment-emergent activation and suicidality assessment profile (TEASAP) in a clinical sample of 56 youth aged 7-17 with obsessive-compulsive disorder (OCD) who participated in a double-blind randomized controlled trial. The 38-item TEASAP demonstrated good internal consistency for its total score (α=0.93) and adequate to good performance for its five subscale scores (α=0.65-0.92). One-week test-retest stability (N=18) was adequate (Intraclass correlation coefficient [ICC]=0.68-0.80) except for Self-Injury (ICC=0.46). Construct validity was supported by total and subscale TEASAP score relationships with related constructs, including irritability, hyperactivity, externalizing behaviors, manic symptoms, and suicidal ideation, and the absence of relationships with unrelated constructs. Predictive validity was established for the Disinhibition subscale through significant associations with subsequent activation events. Furthermore, TEASAP sensitivity to change in activation scores over time was supported by longitudinal associations of TEASAP scores with clinician ratings of activation over the course of treatment. Findings indicate that the TEASAP has acceptable psychometric properties in a clinical sample of youth with OCD and merits further study in larger samples for additional refinement of its measurement approaches.

First-Line Treatment for Pediatric Obsessive–Compulsive Disorder

Pediatric obsessive–compulsive disorder (OCD) is a common psychiatric disorder that impairs children’s functioning in home, school, and community settings. Once thought to be an untreatable or treatment refractory disorder, evidence-based treatments now exist for pediatric OCD. Various psychological treatment approaches for pediatric OCD have been investigated and research supports the use of cognitive-behavioral therapy (CBT) with exposure and response prevention (E/RP) and combined CBT/E/RP with serotonin reuptake inhibitor pharmacotherapy. This paper reviews these approaches and highlights the prominent role of CBT/E/RP as a first-line treatment for pediatric OCD.

Six-Nine Year Follow-Up of Deep Brain Stimulation for Obsessive-Compulsive Disorder

Objective Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) region has shown promise as a neurosurgical intervention for adults with severe treatment-refractory obsessive-compulsive disorder (OCD). Pilot studies have revealed improvement in obsessive-compulsive symptoms and secondary outcomes following DBS. We sought to establish the long-term safety and effectiveness of DBS of the VC/VS for adults with OCD. Materials and Methods A long term follow-up study (73–112 months) was conducted on the six patients who were enrolled in the original National Institute of Mental Health pilot study of DBS for OCD. Qualitative and quantitative data were collected. Results Reduction in OCD symptoms mirrored the one-year follow-up data. The same four participants who were treatment responders after one year of treatment showed a consistent OCD response (greater than 35% reduction in Yale Brown Obsessive Compulsive Scale (YBOCS)). Another subject, classified as a non-responder, achieved a 26% reduction in YBOCS score at long term follow-up. The only patient who did not achieve a 25% or greater reduction in YBOCS was no longer receiving active DBS treatment. Secondary outcomes generally matched the one-year follow-up with the exception of depressive symptoms, which significantly increased over the follow-up period. Qualitative feedback indicated that DBS was well tolerated by the subjects. Discussion These data indicate that DBS was safe and conferred a long-term benefit in reduction of obsessive-compulsive symptoms. DBS of the VC/VS region did not reveal a sustained response for comorbid depressive symptoms in patients with a primary diagnosis of OCD.

Side-effects of SSRIs disrupt multimodal treatment for pediatric OCD in a randomized-controlled trial

OBJECTIVE Activation Syndrome (AS) is a side-effect of antidepressants consisting of irritability, mania, self-harm, akathisia, and disinhibition. The current study was conducted to analyze how AS may hinder treatment outcome for multimodal treatment for children and adolescents with Obsessive-Compulsive Disorder. METHODS Fifty-six children or adolescents were recruited at two treatment sites in a double-blind randomized-controlled trial where participants received Cognitive-Behavioral Therapy and were randomized to slow titration of sertraline, regular titration of sertraline or placebo. RESULTS Using a recently developed measure of AS, results suggested that higher average levels of irritability, akathisia, and disinhibition significantly interfered with treatment response and explained 18% of the variance in obsessive-compulsive symptoms during treatment. Interestingly, only session-to-session increases in irritability resulted in a session-to-session increase in obsessive-compulsive symptoms. The observed results were unchanged with the addition of SSRI dosage as a covariate. CONCLUSIONS Results provide empirical support for the proposed hypothesis that AS may hinder multimodal treatment outcome for pediatric OCD. These findings suggest that dosage changes due to AS do not explain why those with higher AS had worse multimodal outcome. Other possible mechanisms explaining this observed disruption are proposed, including how AS may interfere with Cognitive-Behavioral Therapy.
