Growth Trajectories in Stimulant Treated Children and Adolescents: A Qualitative Review of the Literature from Comprehensive Datasets and Registries.

Objective: Attention-deficit/hyperactivity disorder (ADHD) treatment with stimulant products has been shown to be safe and effective; however, there are remaining concerns about their possible adverse effects on growth trajectories. We conducted a systematic review of the extant literature derived from ecologically valid databases and registries to assess the body of knowledge about the effects of stimulants on growth trajectories in naturalistic samples. Methods: Using PubMed and PsycINFO, we searched for articles published before February 8, 2023 that focused on growth findings associated with stimulant treatment in pediatric ADHD from comprehensive datasets derived from naturalistic population studies. Results: Of the 1070 articles initially identified, 12 met all inclusion criteria. Sample sizes ranged from 157 to 163,820 youths. Seven of 10 articles examining height found significant decreases in height associated with chronic stimulant treatment that normalized over time in 2 studies. Three articles found no significant association between stimulant treatment and height. No clear associations were identified between cumulative duration and dose of stimulant treatment and adult height. All articles examining weight and six of eight articles examining body mass index (BMI) found significant initial decreases that tended to normalize then increase over time. Longer duration of stimulant medication use was predominantly associated with significant weight and BMI reductions. The effects of stimulant dose on weight and BMI were mostly weak and clinically insignificant. Most studies found no significant association between age at start of stimulant treatment and change in height, weight, or BMI. Most studies did not find significant sex effects in relation to growth parameters. Conclusions: This review of ecologically informative samples revealed that the effects of stimulant treatment on growth trajectories are mainly small and transient. These effects seem to be clinically insignificant for most youth with ADHD who receive stimulant treatment from childhood onto adolescence and adulthood.

Further Evidence of an Association Between a Positive Child Behavior Checklist-Bipolar Profile and a Diagnosis of Pediatric Bipolar Disorder: A Meta-Analysis.

Background: Previous research has found that a unique profile of the Child Behavior Checklist comprising of aggregate elevations of the Attention, Anxiety/Depression and Aggression scales (A-A-A profile, CBCL-Bipolar (BP) profile, CBCL-Dysregulation profile (DP); henceforth CBCL-BP/DP profile) is associated with a clinical diagnosis of pediatric bipolar (BP) disorder. Objective: The main aim of the study is to evaluate the strength of the association between the CBCL-BP/DP profile and the clinical diagnosis of pediatric BP disorder through a meta-analysis. Methods: A literature search was performed to identify studies that examined the association between a positive CBCL-BP/DP profile and a clinical diagnosis of pediatric BP disorder. The meta-analyses first examined studies assessing the rates of a positive CBCL-BP/DP profile in youth with BP disorder versus those with 1) ADHD, anxiety/depression, or disruptive behavior disorders (DBDs), and 2) non-bipolar controls. The second analysis evaluated studies examining the rates of pediatric BP disorder in youth with and without a positive CBCL-BP/DP profile. Results: Eighteen articles met our inclusion and exclusion criteria, and fifteen articles had adequate data for meta-analysis. Results showed that BP youth were at significantly increased odds of having a positive CBCL-BP/DP profile compared to those with other psychiatric disorders (i.e., ADHD, anxiety/depression, or DBDs) (pooled OR=4.34, 95% CI=2.82, 8.27; p<0.001) and healthy control groups (pooled OR=34.77, 95% CI=2.87, 420.95; p=0.005). Further, meta-analysis results showed that youth with a positive CBCL-BP/DP profile were at significantly increased odds of having a BP disorder diagnosis compared to those without (pooled OR=4.25, 95% CI=2.12, 8.52; p<0.001). Conclusion: Our systematic review and meta-analysis of the extant literature provides strong support for the association between the CBCL-BP/DP profile and pediatric BP disorder.

Toward Operationalizing Executive Function Deficits in Adults With ADHD Using the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A).

Objective: Although group findings document that executive function deficits (EFDs) contribute to the morbidity associated with adult attention-deficit/hyperactivity disorder (ADHD), it is unclear whether easy-to-use assessment methods can aid in the identification of EFDs at the individual level. The aim of the present study was to assess whether the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A), a well-standardized, self-report instrument that assesses behavioral concomitants of EFDs, can serve that purpose.Methods: 1,090 consecutively referred 18- to 55-year-old adults of both sexes who were clinically referred for the evaluation and treatment of ADHD between June 2016 and December 2021 completed a battery of scales assessing several non-overlapping domains of functioning. Because the BRIEF Global Executive Composite (GEC) offers a single point summary of all other BRIEF-A scales, we used receiver operator characteristic (ROC) curves to identify the optimal cutoff on the BRIEF-A GEC to categorize patients as having executive dysfunction.Results: We averaged the optimal BRIEF-A GEC cut-points from the ROC curve analyses to categorize patients with (N = 480; 44%) and without (N = 610; 56%) EFDs (BRIEF-A GEC score ≥ 70 or < 70, respectively). Adults with ADHD with EFDs had significantly more severe ADHD symptoms (ADHD Self-Report Scale scores ≥ 24: 94% vs 41%, P < .001); higher levels of psychopathology (Adult Self Report Total Problems T-scores ≥ 64: 75% vs 19%, P < .001), emotional dysregulation (69% vs 23%, P < .001), mind wandering (84% vs 48%, P < .001), and symptoms of autism (Social Responsiveness Scale T-scores ≥ 66: 24% vs 3%, P < .001); and worse quality of life (Quality of Life Enjoyment and Satisfaction Questionnaire mean scores: 44.4 ± 8.2 vs 51.9 ± 8.5, P = .001) compared to those without EFDs. There were no major differences in outcomes by age, sex, or race.Conclusions: The BRIEF-A helped identify a sizeable minority of adults with ADHD with behavioral concomitants of EFDs that added substantial morbidity and disability beyond that expected by having ADHD alone.

Disentangling the heterogeneity of emotional dysregulation in referred youth using the Child Behavior Checklist attending to age and sex effects.

PURPOSE: To assess the utility of the Child Behavior Checklist (CBCL) to identify meaningful subtypes of emotional dysregulation in an outpatient pediatric psychiatry clinic. METHODS: The sample consisted of 417 newly referred youth 6-18 years of age. Parents completed the CBCL and rating scales measuring executive function deficits, social functioning, and quality of life. Patients were stratified into subtypes of emotional dysregulation and compared on clinical correlates based on the A-A-A profile consisting of the CBCL Anxious/Depressed, Aggressive Behavior, and Attention Problems (A-A-A) scales. RESULTS: 67% of youth had emotional dysregulation (CBCL A-A-A T-score ≥ 180) and of these, 39% had a positive CBCL-Bipolar (BP) profile (A-A-A T-score ≥ 210), 24% had depression without the BP profile (CBCL Anxious/Depressed and/or Withdrawn/Depressed T-scores ≥70 and A-A-A T-score ≥ 180 and ã€ˆ210), and 37% had emotional impulsivity (A-A-A T-score ≥ 180 and <210) with normal CBCL Anxious/Depressed and Withdrawn/Depressed T-scores. Patients with the CBCL-BP profile were significantly more impaired on all measures of social and executive functioning compared to the other two groups. LIMITATIONS: Since our findings relied on the CBCL, other instruments may have led to different results. Because we included youth from a single clinic, largely Caucasian and referred, our findings may not generalize to other ethnic groups or settings. CONCLUSIONS: The CBCL can aid in the identification of subtypes of emotional dysregulation affecting youth seeking mental health services.

Rates of switching stimulants in consecutively referred medication naïve adults with ADHD.

OBJECTIVE: To evaluate the frequency and correlates of needing to switch the initial treatment with a stimulant medication to the alternative family in newly referred, untreated adults with ADHD initiating treatment. METHODS: Subjects were consecutively referred unmedicated adults with DSM-5 ADHD who initiated stimulant treatment. Before assessment with an expert clinician, participants completed a battery of self-report measures to assess psychopathology, executive functioning, emotional dysregulation, and mind wandering. The rate of switching was examined using information from electronic medical records for up to three clinical follow-up visits. Those who did and did not need to switch were compared on baseline demographic and clinical characteristics. RESULTS: Twenty-four percent (N = 21/86) of ADHD patients needed to switch from their initially prescribed stimulant family within 60 days of initiating treatment due to poor tolerability. While the rate of switching was significantly higher in those initially prescribed MPH, the rate of patients requiring changes in formulation or additional antianxiety or antidepressant treatment was higher in those taking AMPH. There were some hints about predictive risk factors for switching by the presence of emotional dysregulation and depressive symptoms, depending on age and sex. CONCLUSIONS: These findings call for improved efforts to help identify predictors of response to stimulant treatment in adults with ADHD to avoid unnecessary delays in identifying safe and effective treatments for these patients.

The child behavior checklist can aid in characterizing suspected comorbid psychopathology in clinically referred youth with ADHD.

OBJECTIVE: To examine the utility of the Child Behavior Checklist (CBCL) to aid in the identification of comorbid psychopathological conditions affecting referred youth with suspected ADHD prior to the evaluation. The CBCL is an easy-to-use assessment tool that may provide invaluable information regarding the severity and characteristics of the presenting complaints. METHODS: The sample included 332 youths consecutively referred to an ADHD program for the assessment of suspected ADHD. Parents completed the CBCL, parent-rated ADHD Self-Report Scale (ASRS), Social Responsiveness Scale (SRS), and Behavior Rating Inventory of Executive Function (BRIEF). Because of the established association between the CBCL Attention Problems scale and a structured diagnostic interview of ADHD, all youths analyzed had abnormal Attention Problems T-scores (≥60). RESULTS: Seventy-six percent of youths with elevated Attention Problems T-scores had ≥3 additional abnormal CBCL scales, suggesting they were likely affected with multiple comorbid psychopathological conditions. Moreover, 44% had ≥1 CBCL clinical scale with a T-score more severe than their Attention Problems T-score, suggesting the putative comorbid condition was more severe than the ADHD symptoms. Additional CBCL scale elevations were associated with more severe functional impairments as assessed by the ASRS, SRS, BRIEF, and CBCL competence scales. CONCLUSION: The CBCL obtained before the clinical assessment identified high rates of comorbid psychopathology in youths referred for the assessment of ADHD. It provided detailed information about the types and severity of suspected psychopathological conditions impacting a particular youth, which is critical to guide the assessing clinician on likely differing needs of the affected child.

How Frequent Is Switching From an Initial Stimulant Family to the Alternative One in the Clinical Setting?: A Pilot Study of 49 Consecutively Referred Medication-Naive Adults With Attention-Deficit/Hyperactivity Disorder.

PURPOSE/BACKGROUND: This study aimed to evaluate the frequency of needing to switch the initial treatment of a stimulant to the alternative family in newly referred, medication-naive adults with attention-deficit/hyperactivity disorder (ADHD) initiating treatment with stimulants. METHODS/PROCEDURES: Subjects were 49 unmedicated adults (18-45 years old) with Diagnostic and Statistical Manual of Disorders (Fifth Edition) ADHD who initiated treatment with a stimulant. Before the clinical assessment with an expert clinician, participants completed the Adult Self-Report, Behavior Rating Inventory of Executive Function-Adult Version, Emotional Dysregulation Subscale of the Barkley Current Behavior Scale-Self-report, and Mind Wandering Questionnaire. The rate of switching was examined using information from the electronic medical record for up to three clinical follow-up visits. Comparisons were made between those who did and did not need to switch on baseline demographic and clinical characteristics. FINDINGS/RESULTS: Sixty-seven percent of ADHD patients were initially prescribed a methylphenidate product, and 33%, an amphetamine product. Forty-one percent of ADHD patients needed to switch from their initially prescribed stimulant family within 90 days of initiating treatment because of poor tolerability. Whereas the rate of switching was significantly higher in those initially prescribed methylphenidate, the rate of patients who required changes in formulation (long- to short-acting and vice versa) or additional antianxiety or antidepressant treatment ("strugglers") was higher in those taking amphetamine. Switchers were more impaired on the Adult Self-Report Intrusive scale, whereas nonswitchers were more impaired on the Behavior Rating Inventory of Executive Function Inhibit and Task Monitor scales. However, these findings were small and of unclear clinical significance. IMPLICATIONS/CONCLUSIONS: Forty-one percent of medication-naive adults with ADHD initiating stimulant treatment required a switch from the initially prescribed stimulant family to the alternative one because of poor tolerability. Switching could not be adequately predicted by baseline demographic or clinical characteristics. These findings call for improved efforts to help identify predictors of response to stimulant treatment in adults with ADHD to avoid unnecessary delays in identifying a safe and effective treatment for these patients.

Further evidence of low adherence to stimulant treatment in adult ADHD: an electronic medical record study examining timely renewal of a stimulant prescription.

RATIONALE: ADHD is a prevalent and morbid neurobiological disorder affecting up to 5% of adults. While stimulants have been documented to be safe and effective in adults with ADHD, uncertainties remain about adherence to these treatments. OBJECTIVES: The main aim of this article was to evaluate contemporaneous rates and correlates of adherence to stimulants in adults with ADHD using data from electronic medical records from a large healthcare organization focusing on timely renewal of an initial prescription. METHODS: Subjects were patients 18 to 44 years of age who had been prescribed a stimulant between January 1, 2015, and December 31, 2016. Prescription and sociodemographic data were extracted from the Partners HealthCare Research Patient Data Registry (RPDR). Our outcome metric was renewal of the index stimulant prescription defined as the first prescription recorded in the electronic record for the period under investigation. RESULTS: We identified 2689 patients with an index prescription for a stimulant medication. Results showed that only 42% of patients renewed their prescriptions in a timely enough fashion to be considered consistently medicated. CONCLUSIONS: Results indicate that adults with ADHD have a low rate of renewal of their initial stimulant prescription indicating poor patient engagement in their treatment for ADHD.

Prior Authorizations: A Necessary Evil?

Along with general practice burdens, child and adolescent psychiatrists (CAPs) are commonly tasked with completing prior authorizations (PAs) for medications prescribed in clinical practice. CAPs frown in resignation to their PA requirements to allow patients to be initiated onto, or continue with, their medications. PAs are often required for both brand and generic prescription medications, sometimes to confirm if the medication is medically necessary and appropriate for the indication,1 to review medication dosages, or more commonly to review the need in context to the medication cost of the requested agent relative to less expensive alternatives. Some states have implemented policies that leverage PAs to regulate and oversee provider prescribing patterns. Notably, many state Medicaid programs have restrictions on prescription of antipsychotics in children, and adoption of these regulations has led to decreases in their use in children 6 to 12 years old.2.

A novel digital health intervention to improve patient engagement to stimulants in adult ADHD in the primary care setting: Preliminary findings from an open label study.

AIMS: We piloted the effectiveness and acceptability of a novel text messaging-based (SMS) digital health intervention aimed at addressing the previously documented poor rate of patient engagement in stimulant treatment in the primary care setting. METHODS: 117 adults ages 18-55 from primary care and psychiatric practices who were prescribed a stimulant medication for ADHD treatment received the SMS intervention. Comparators were age-, race-, and sex-matched patients from the same health care organization's electronic medical record who had been prescribed stimulant medications over a similar time period. Using documented prescription records, we determined whether patients had timely prescription refills. RESULTS: Ninety-six percent (N = 112) of participants completed our a priori metric of patient engagement consisting of 37 days of the SMS program. Eighty-one percent of participants refilled their index prescriptions in a timely manner compared to only 36% of patients receiving treatment as usual (OR=7.54, 95% CI: 4.46, 12.77; p<0.001). We found no significant interaction between prescribing source (non-psychiatry vs. psychiatry) and intervention group (SMS vs. treatment as usual). CONCLUSIONS: These data suggest that an ADHD-centric, digital health intervention using text messaging significantly improves patient engagement in stimulant treatment in adults with ADHD.

High Correspondence Between Child Behavior Checklist Rule Breaking Behavior Scale with Conduct Disorder in Males and Females.

This study investigated the diagnostic utility of the Child Behavior Checklist (CBCL) Rule-Breaking Behavior scale to identify children of both sexes with conduct disorder (CD). Participants were derived from four independent datasets of children with and without attention deficit hyperactivity disorder and bipolar-I disorder of both sexes. Participants had structured diagnostic interviews with raters blinded to subject ascertainment status. Receiver operating characteristic (ROC) curves were used to examine the scale's ability to identify children with and without CD. The sample consisted of 674 participants (mean age of 11.7 ± 3.3 years, 57% male, 94% Caucasian). The interaction to test if CBCL Rule-Breaking Behavior scores identified males and females with CD differently was not significant, thus we performed ROC analysis in the combined group. The ROC analysis of the scale yielded an area under the curve of 0.9. A score of ≥ 60 on the scale correctly classified 82% of participants with CD with 85% sensitivity, 81% specificity, 48% positive predictive value, 96% negative predictive value. The CBCL Rule-Breaking Behavior scale was an efficient tool to identify children with CD.

Toward operationalizing deficient emotional self-regulation in newly referred adults with ADHD: A receiver operator characteristic curve analysis.

BACKGROUND: A growing body of research suggests that deficient emotional self-regulation (DESR) is common and morbid among attention-deficit/hyperactivity disorder (ADHD) patients. The main aim of the present study was to assess whether high and low levels of DESR in adult ADHD patients can be operationalized and whether they are clinically useful. METHODS: A total of 441 newly referred 18- to 55-year-old adults of both sexes with Diagnostic and Statistical Manual of Mental Disorders: Fifth Edition (DSM-5) ADHD completed self-reported rating scales. We operationalized DESR using items from the Barkley Current Behavior Scale. We used receiver operator characteristic (ROC) curves to identify the optimal cut-off on the Barkley Emotional Dysregulation (ED) Scale to categorize patients as having high- versus low-level DESR and compared demographic and clinical characteristics between the groups. RESULTS: We averaged the optimal Barkley ED Scale cut-points from the ROC curve analyses across all subscales and categorized ADHD patients as having high- (N = 191) or low-level (N = 250) DESR (total Barkley ED Scale score ≥8 or <8, respectively). Those with high-level DESR had significantly more severe symptoms of ADHD, executive dysfunction, autistic traits, levels of psychopathology, and worse quality of life compared with those with low-level DESR. There were no major differences in outcomes among medicated and unmedicated patients. CONCLUSIONS: High levels of DESR are common in adults with ADHD and when present represent a burdensome source of added morbidity and disability worthy of further clinical and scientific attention.

An innovative SMS intervention to improve adherence to stimulants in children with ADHD: Preliminary findings.

BACKGROUND: Although large datasets document that stimulants decrease the risk for many adverse ADHD-associated outcomes, compliance with stimulants remains poor. AIMS: This study examined the effectiveness of a novel ADHD-centric text messaging-based intervention aimed to improve adherence to stimulant medications in children with ADHD. METHODS: Subjects were 87 children aged 6-12, who were prescribed a stimulant medication for ADHD treatment. Prescribers gave permission to contact their patients for participation in the study. Subjects were primarily from the primary care setting with a subsample of psychiatrically referred subjects for comparison. Age- and sex-matched comparators were identified (3:1) from the same pool of prescriber-approved subjects that did not participate. Timely prescription refills (within 37 days) were determined from prescription dates documented in patients' electronic medical record. RESULTS: Eighty-five percent of SMS intervention patients refilled their prescriptions in a timely manner compared with 62% of patients receiving treatment as usual (OR = 3.46, 95% CI: 1.82, 6.58; p < 0.001). The number needed to treat statistic was computed as five, meaning for every five patients who receive the SMS intervention, we can keep one adherent to their stimulant treatment. CONCLUSIONS: These preliminary findings support the potential utility of a readily accessible technology to improve the poor rate of adherence to stimulant treatment in children with ADHD. To the best of our knowledge, this study is the first digital health intervention aimed at improving adherence to stimulant medication for children with ADHD. These results support the need for further examination of this technology through more definitive randomized clinical trials.

A literature review and meta-analysis on the effects of ADHD medications on functional outcomes.

OBJECTIVE: To conduct a systematic review and meta-analysis of literature from large databases and registries to assess the effects of ADHD medication on associated functional outcomes. STUDY DESIGN: A literature search was performed in PubMed, PsycINFO, MEDLINE, and Web of Science for articles published prior to January 2019. Sample size, age range, country of origin, medication type, number of functional events and non-events, odds ratios and hazard ratios, and means and standard deviations were extracted. Random-effects meta-analyses were conducted for 21 studies examining functional outcomes. RESULTS: 40 articles were included. The majority suggest a robust protective effect of ADHD medication treatment on mood disorders, suicidality, criminality, substance use disorders, accidents and injuries, traumatic brain injuries, motor vehicle crashes, and educational outcomes. Similarly, the meta-analyses demonstrated a protective effect of medication treatment on academic outcomes, accidents and injuries, and mood disorders. CONCLUSIONS: These findings suggest that ADHD medication treatments are associated with decreases in the risks for a wide range of ADHD-associated functional outcomes supporting efforts aimed at early diagnosis and treatment of individuals with ADHD.

Is Paternal Smoking at Conception a Risk for ADHD? A Controlled Study in Youth With and Without ADHD.

Objective: Based on emerging preclinical findings suggesting that paternal smoking at conception may be a risk for ADHD in the offspring, we investigated whether a similar effect can be observed in humans. Method: We analyzed data from an opportunistic dataset of girl probands with (N = 140) and without (N = 122) ADHD with available information on paternal smoking at conception. Data were analyzed using Pearson's chi-square tests and multiple logistic regression. Results: ADHD probands had a significantly higher rate of paternal smoking at conception than controls (35% vs. 23%, χ2 = 3.82, p = .05) with a significant odds ratio of 1.5. However, the association lost significance after controlling for paternal ADHD, most likely due to limited statistical power. Conclusion: While preliminary, findings suggest that paternal smoking at conception may be a risk factor for ADHD in the offspring.

Quantifying the Protective Effects of Stimulants on Functional Outcomes in Attention-Deficit/Hyperactivity Disorder: A Focus on Number Needed to Treat Statistic and Sex Effects.

PURPOSE: The aim of the study was to help quantify the protective effects of stimulant treatment on important functional outcomes in attention-deficit/hyperactivity disorder (ADHD) using the number needed to treat (NNT) statistic and examine whether these effects are moderated by sex. METHODS: Subjects were derived from three independent samples, two similarly designed case-control, 10-year prospective follow-up studies of boys and girls with and without ADHD grown up and a cross-sectional randomized clinical trial of lisdexamfetamine on driving performance and behavior. For all studies, subjects were evaluated with structured diagnostic interviews. To measure psychopharmacologic treatment in the follow-up studies, we collected information about each subject's stimulant medication use, age at onset, and age at termination of treatment. Subjects in the driving study underwent two driving simulation assessments (premedication and after 6 weeks of treatment on lisdexamfetamine or placebo). For each outcome, we ran a logistic regression model that included an interaction between sex and treatment status. Lifetime rates were used to calculate the NNT statistic. We also calculated adjusted NNT statistics that accounted for sex, age, socioeconomic status, and family intactness. RESULTS: The NNTs were very low, ranging from 3 to 10. No interaction effects with sex were detected (all p > .05). The adjusted NNTs mostly remained the same with the exception of any substance use disorder, which increased after controlling for age. CONCLUSIONS: Stimulants have strong protective effects on functional outcomes in youth with ADHD that are not moderated by sex. These results support the critical importance of early identification and treatment of children with ADHD of both sexes.

Clinical correlates of mind wandering in adults with ADHD.

The objective of this study was to investigate the prevalence and clinical correlates of ADHD patients with mind wandering. 255 consecutively referred 18- to 55-year-old adults of both sexes with ADHD were assessed. Subjects completed a demographic interview, the Mind Wandering Questionnaire (MWQ), the ADHD Rating Scale (ADHD RS), the Behavior Rating Inventory of Executive Function - Adult Version (BRIEF-A), the Social Responsiveness Scale - Second Edition (SRS-2) Adult Self-Report Form, the Adult Self-Report (ASR), the Barkley Emotional Dysregulation Scale, and the Quality of Life Enjoyment & Satisfaction Questionnaire (Q-LES-Q). We used receiver operator characteristic (ROC) curves to identify the optimal cut-off on the MWQ to categorize patients as having high-versus low-level mind wandering and compared demographic and clinical characteristics between the two groups. Participants were categorized by ROC analysis as having high- (N = 127) and low-level (N = 128) mind wandering based on an MWQ total score ≥ or < than 24, respectively. Compared with low-level mind wandering participants, those with high-level mind wandering had significantly more Inattentive and Hyperactive symptoms (all p < 0001), worse executive functioning as measured by the BRIEF-A, more impaired mean (all p ≤ 0.001) and dichotomized scores (t-score ≥65) (all p < 0.005) on subscales and composite ASR scales, more impaired scores on the Barkley Emotional Dysregulation Scale (p < 0.001), and more impaired quality of life scores. High-level mind wandering is prevalent in adults with ADHD and is associated with more severe ADHD symptoms, more executive function deficits, more emotional dysregulation, higher levels of associated psychopathology, and more impaired quality of life.

Evidence of Low Adherence to Stimulant Medication Among Children and Youths With ADHD: An Electronic Health Records Study.

OBJECTIVE: The objective of this study was to evaluate rates and correlates of stimulant medication adherence in a sample of pediatric patients using data derived from electronic medical records (EMRs) from a large health care organization in a large metropolitan area. The study relied on a novel definition of medication adherence as a timely renewal of an index prescription determined using the electronically recorded issuance of a stimulant prescription in the EMR ("refill"). METHODS: Prescription and sociodemographic data were extracted from the Partners HealthCare Research Patient Data Registry to calculate adherence to stimulant medication treatment. RESULTS: In the EMR, 2,206 patients with prescriptions for central nervous system stimulant medication were identified. Results showed that 46% of the index prescriptions were refilled within the timeframe necessary for the patient to be considered consistently medicated. A multivariable logistic regression model predicting medication adherence from patient demographic and treatment characteristics yielded an area-under-the-curve statistic of 0.57, indicating that these characteristics predicted adherence only modestly better than chance. CONCLUSIONS: EMR data from a large health care organization showed that 46% of pediatric patients were adherent to treatment with stimulants. Rates of medication adherence were worse among patients receiving care from a primary care provider than among those receiving care from a psychiatrist, in older patients, and in female patients and did not appear to be influenced by racial-ethnic group, economic class, stimulant type, or medication formulation (short or long acting). These findings, which show low rates of medication adherence among children and adolescents with ADHD, suggest the need for efforts to improve these rates.

A Novel Text Message Intervention to Improve Adherence to Stimulants in Adults With Attention Deficit/Hyperactivity Disorder.

BACKGROUND: Attention deficit/hyperactivity disorder (ADHD) is a prevalent neurobiological disorder associated with a wide range of adverse outcomes. Although large data sets document that stimulants decrease the risks for many ADHD-associated adverse outcomes, compliance with stimulants remains very poor. The main aim of this study was to assess the effectiveness of a novel text messaging-based intervention aimed at improving the poor rate of adherence to stimulant medications in adults with ADHD. METHODS: Subjects were adults with ages 18 to 55, prescribed a stimulant medication for ADHD treatment. For comparators, we identified at a 5-to-1 ratio (age and sex matched) adult patients from the Partners HealthCare electronic medical record who had been prescribed stimulant medications over a 1-year period. We determined whether patients had timely prescription refills, defined as refilled within 37 days, using prescriptions documented in their electronic medical record. RESULTS: Our results showed that 68% of the SMS intervention group refilled their prescriptions in a timely manner. In contrast, only 34% of patients receiving treatment as usual refilled their prescriptions in a timely fashion (odds ratio, 4.04; 95% confidence interval, 2.49-6.56; P < 0.001). CONCLUSIONS: These data indicate that an innovative ADHD-centric text messaging intervention significantly improved patient engagement to treatment with stimulants in adults with ADHD. Findings provide strong support for the use of a readily accessible, inexpensive, and widely available technology to improve the poor rate of adherence to stimulant treatment in adults with ADHD. To the best of our knowledge, this study is the first digital health intervention aimed at improving adherence to stimulant medication for adults with ADHD.

Are subsyndromal manifestations of attention deficit hyperactivity disorder morbid in children? A systematic qualitative review of the literature with meta-analysis.

We conducted a qualitative review (n = 15 manuscripts) and meta-analysis (n = 9 manuscripts) of the extant literature to evaluate the prevalence and morbidity of subthreshold Attention Deficit Hyperactivity Disorder (ADHD). Our qualitative review showed that a sizable minority (mean: 17.7%) of clinically referred and non-referred children met a priori definitions of subthreshold ADHD. Those affected exhibited significantly higher rates of family dysfunction, cognitive impairment, executive dysfunction, interpersonal and school deficits, temperament problems, psychiatric comorbidity, and juvenile delinquency compared to children with no ADHD symptoms. These deficits were highly consistent with those observed in children with full threshold ADHD. These findings indicate that children with subthreshold ADHD symptoms are at significantly greater risk for negative outcomes in a wide range of non-overlapping functional domains worthy of further clinical and scientific consideration.
