Objective . This study examined the efficacy of 2 computer-based training systems to teach children with attention deficit/hyperactivity disorder ( ADHD ) to attend more effectively . Design / methods . A total of 41 children with ADHD from 2 middle schools were r and omly assigned to receive 2 sessions a week at school of either neurofeedback ( NF ) or attention training through a st and ard computer format ( SCF ) , either immediately or after a 6-month wait ( waitlist control group ) . Parents , children , and teachers completed question naires pre- and postintervention . Results . Primary parents in the NF condition reported significant ( P < .05 ) change on Conners ’s Rating Scales — Revised ( CRS-R ) and Behavior Assessment Scales for Children ( BASC ) subscales ; and in the SCF condition , they reported significant ( P < .05 ) change on the CRS-R Inattention scale and ADHD index , the BASC Attention Problems Scale , and on the Behavioral Rating Inventory of Executive Functioning ( BRIEF ) . Conclusion . This r and omized control trial provides preliminary evidence of the effectiveness of computer-based interventions for ADHD and supports the feasibility of offering them in a school setting Background The aims of this study were to determine the time course of improvements in attention deficit hyperactivity disorder ( ADHD ) clinical symptoms and neurocognitive function in a realistic clinical setting , and the differences in ADHD symptom improvement using different classifications of ADHD subtypes . Methods The Child Behavior Checklist ( CBCL ) was completed by parents of ADHD children at the initial visit . The  computerized Continuous Performance Test ( CPT ) , Swanson , Nolan , and Pelham , and Version IV Scale for ADHD ( SNAP-IV ) , and  ADHD Rating Scale ( ADHD-RS ) were performed at baseline , one month , three months , and six months later , respectively . Patient care including drug therapy was performed at the discretion of the psychiatrist . The ADHD patients were divided into DSM-IV subtypes ( Inattentive , Hyperactive-impulsive and Combined type ) , and were additionally categorized into aggressive and non-aggressive subtypes by aggression scale in CBCL for comparisons . Results There were 50 ADHD patients with a mean age of 7.84 ± 1.64 years ; 15 of them were inattentive type , 11 were hyperactive-impulsive type , and 24 were combined type . In addition , 28 of the ADHD patients were grouped into aggressive and 22 into non-aggressive subtypes . There were significant improvements in clinical symptoms of hyperactivity and inattention , and impulsivity performance in CPT during the 6-month treatment . The clinical hyperactive symptoms were significantly different between ADHD patients sub-grouping both by DSM-IV and aggression . Non-aggressive patients had significantly greater changes in distraction and impulsivity performances in CPT from baseline to month 6 than aggressive patients . Conclusions We found that ADHD symptoms , which included impulsive performances in CPT and clinical inattention and hyperactivity dimensions , had improved significantly over 6 months under pragmatic treatments . The non-aggressive ADHD patients might have a higher potential for improving in CPT performance than aggressive ones . However , it warrant further investigation whether the different classifications of ADHD patients could be valid for predicting the improvements in ADHD patients ' clinical symptoms and neurocognitive performance BACKGROUND Intent-to-treat analyses of the study revealed that medication management , alone or combined with intensive behavioral treatment , was superior to behavioral treatment and community care in reducing attention-deficit/hyperactivity disorder ( ADHD ) symptoms ; but only combined treatment showed consistently greater benefit than community care across other outcome domains ( disruptive and internalizing symptoms , achievement , parent-child relations , and social skills ) . We examine response patterns in subgroups defined by baseline variables ( moderators ) or variables related to treatment implementation ( mediators ) . METHODS We reconducted r and om-effects regression ( RR ) analyses , adding factors defined by moderators ( sex ,  prior medication use  ,  comorbid disruptive or anxiety disorder  , and public assistance ) and a mediator ( treatment acceptance/attendance ) . RESULTS Study outcomes ( N = 579 ) were upheld in most moderator subgroups ( boys and girls , children with and without prior medication , children with and without comorbid disruptive disorders ) . Comorbid anxiety disorder did moderate outcome ; in participants without anxiety , results paralleled intent-to-treat findings . For those with anxiety disorders , however , behavioral treatment yielded significantly better outcomes than community care ( and was no longer statistically different from medication management and combined treatment ) regarding ADHD-related and internalizing symptoms . In families receiving public assistance , medication management yielded decreased closeness in parent-child interactions , and combined treatment yielded relatively greater benefits for teacher-reported social skills . In families with high treatment acceptance/attendance , intent-to-treat results were upheld . Acceptance/attendance was particularly important for medication treatments . Finally , two thirds of children given community care received stimulants . Behavioral treatment did not significantly differ from , but medication management was superior to , this subgroup . CONCLUSIONS Exploratory analyses revealed that our study ( the Multimodal Treatment Study of Children With Attention-Deficit/Hyperactivity Disorder [ MTA ] ) results were confirmed across most baseline variables and treatment acceptance/attendance . In children with ADHD plus anxiety , behavioral treatment surpassed community care and approached medication-based treatments regarding parent-reported ADHD symptoms The aim of this study was to determine drug-dependent effects on attention and motor activity in children with attention-deficit/hyperactivity disorder ( ADHD ) in a double-blind methylpheni date ( MPH ) trial using both subjective behavior ratings and objective measures of function . In particular , we were interested in the relationship between changes of those subjective and objective measures . A total of 44 ADHD children with the combined subtype completed a r and omized , double-blind , placebo-controlled , crossover trial with 2 doses of MPH ( 0.25 ; 0.5 mg/kg body weight ) and placebo . In each condition , computerized attention tasks were performed , teacher-behavior ratings were obtained , and actigraph data were collected in both clinical and naturalistic setting s. Trend tests revealed linear effects of MPH dose on actigraph data in the test session ( p = 0.02 ) and at school ( p = 0.001 ) , as well as on sustained attention ( p < 0.001 ) , while inhibitory control showed a quadratic dose-response curve ( p < 0.001 ) . Multivariate regression analyses revealed that changes of both , hyperactive-impulsive symptoms ( 28 % ) and inattentive symptoms ( 23 % ) could be explained by objective changes of motor activity . Thus , for clinical practice , it should be taken into account that behavior ratings of ADHD symptoms seemed to be predominantly influenced by changes of motor activity In 1992 , the National Institute of Mental Health and 6 teams of investigators began a multisite clinical trial , the Multimodal Treatment of Attention-Deficit Hyperactivity Disorder ( MTA ) study . Five hundred seventy-nine children were r and omly assigned to either routine community care ( CC ) or one of three study -delivered treatments , all lasting 14 months . The three MTA treatments-monthly medication management ( usually methylpheni date ) following weekly titration ( MedMgt ) , intensive behavioral treatment ( Beh ) , and the combination (Comb)-were design ed to reflect known best practice s within each treatment approach . Children were assessed at four time points in multiple outcome . Results indicated that Comb and MedMgt interventions were substantially superior to Beh and CC interventions for attention-deficit hyperactivity disorder symptoms . For other functioning domains ( social skills , academics , parent-child relations , oppositional behavior , anxiety/depression ) , results suggested slight advantages of Comb over single treatments ( MedMgt , Beh ) and community care . High quality medication treatment characterized by careful yet adequate dosing , three times daily methylpheni date administration , monthly follow-up visits , and communication with schools conveyed substantial benefits to those children that received it . In contrast to the overall study findings that showed the largest benefits for high quality medication management ( regardless of whether given in the MedMgt or Comb group ) , secondary analyses revealed that Comb had a significant incremental effect over MedMgt ( with a small effect size for this comparison ) when categorical indicators of excellent response and when composite outcome measures were used . In addition , children with parent-defined comorbid anxiety disorders , particularly those with overlapping disruptive disorder comorbidities , showed preferential benefits to the Beh and Comb interventions . Parental attitudes and disciplinary practice s appeared to mediate improved response to the Beh and Comb interventions BACKGROUND In the recent past , psychiatrists and paediatricians have avoided prescribing stimulant medication , such as methylpheni date and dexamphetamine to patients with autism spectrum disorders ( ASD ) because of both doubts about efficacy and concern that these medications make stereotypies worse . Recently , a number of small trials have suggested that methypheni date does have a role in the management of hyperactivity in children with autistic spectrum disorders . METHODS Children with ASD and attention deficit hyperactivity disorder ( ADHD ) , and children with ADHD without ASD received st and ard treatment with methypheni date from one specialist centre . A combination of st and ardized and novel outcome tools was used to allow both an exploratory retrospective study of 174 children and then a prospect i ve study of a further 52 children to be carried out . RESULTS After treatment with stimulants , the subjects in both groups showed statistically significant improvements in target symptoms of ' hyperactivity ' , ' impulsivity ' , ' inattention ' , ' oppositionality ' , ' aggression ' and ' intermittent explosive rage ' . The Clinical Global Impression-Improvement and efficacy index measures also improved in each group . In both the retrospective and the prospect i ve studies , there was no statistically significant difference in the degree of improvements between each group . Importantly , neither tics nor repetitive behaviours worsened in either group . Children in the ' ADHD-only ' group who were prescribed stimulants experienced significant ' nausea ' , ' giddiness ' , ' headaches ' and ' sleep difficulties ' , whereas sleep difficulties were the only side effect that emerged in children in the ASD with ADHD group . CONCLUSIONS Both studies presented here support previous findings from smaller studies that show children with autism and ADHD can respond as well to stimulants as children with ADHD alone . Although r and omized controlled trials remain the gold st and ard for efficacy studies , systems like this that allow clinicians to continue rigorous and consistent monitoring for many years have a valuable role to play . Furthermore , such monitoring systems which now exist electronically can easily accumulate large data sets and reveal details about long-term effectiveness and long-term side effects of medication that are unlikely to be discovered in short-term trials ABSTRACT . The objective of this study was to evaluate the effectiveness of an 8-week behavioral and social skill ( BSS ) class for children newly diagnosed with attention-deficit hyperactivity disorder ( ADHD ) and their parents , initiating stimulant treatment in primary care . The subjects were 100 children , aged 5 to 12 years , recently diagnosed with ADHD and treated with stimulant medication , and their parents or guardians . Eligible families were r and omly assigned to an intervention group ( IG : n = 59 ) or control group ( CG : n = 41 ) . The BSS function of each child was assessed using DuPaul ’s ADHD Parent Rating Scale ( 18-item ) and Child Attention Profile ( 12-item ) during blinded baseline and follow-up interviews . Parent discipline practice was assessed using a five-item inventory based on Likert-scale ratings during identical periods . Computerized pharmacy records were used to track psychostimulant use over time . IG children exhibited significantly lower parent-rated ADHD symptoms , whereas IG parents reported significantly better and more consistent discipline practice s compared with CG parents across time . No significant differences were found between groups in Child Attention Profile scores across time . Psychostimulant use did not significantly differ between groups across time .  BSS training  was well accepted and seemed to significantly improve BSS functioning among IG children in the home setting only OBJECTIVE To determine the efficacy of group cognitive-behavioral therapy ( CBT ) on adolescents with attention-deficit/hyperactivity disorder ( ADHD ) who were in pharmacological treatment but still had persistent symptoms . METHOD We conducted a multicenter , r and omized , rater-blinded , controlled trial between April 2012 and May 2014 in a cohort of 119 adolescents ( 15 - 21 years of age ) . Participants were r and omly assigned to 12 manualized group CBT sessions ( n = 45 ) or a waiting list control group ( n = 44 ) . Primary outcomes were assessed by a blinded evaluator ( ADHD Rating Scale [ ADHD-RS ] , Clinical Global Impression Scale for Severity [ CGI-S ] , Global Assessment of Functioning [ GAF ] ) before and after treatment , as well as by self-report and parent informant ratings . RESULTS Of the initial 119 participants enrolled , 89 completed treatment . A mixed-effects model analysis revealed that participants who were assigned to the group CBT sessions experienced significantly reduced ADHD symptoms compared to the control group ( ADHD-RS Adolescent : -7.46 , 95 % CI = -9.56 to -5.36 , p < .001 , d = 7.5 ; ADHD-RS Parents : -9.11 , 95 % CI = -11.48 to -6.75 , p < .001 , d = 8.38 ; CGI-S Self-Report : -0.68 , 95 % CI = -0.98 to -0.39 , p < .001 , d = 3.75 ; CGI-S Clinician : -0.79 , 95 % CI = -0.95 to -0.62 , p < .001 ; d = 7.71 ) . Functional impairment decreased significantly in the CBT group according to parents ( Weiss Functional Impairment Scale -4.02 , 95 % CI = -7.76 to -0.29 , p < .05 , d = 2.29 ) and according to the blinded evaluator ( GAF : -7.58 , 95 % CI = -9.1 to -6.05 , p < .001 , d = 7.51 ) . CONCLUSION Group CBT associated with pharmacological treatment is an efficacious intervention for reducing ADHD symptoms and functional impairment in adolescents . Clinical trial registration information-CBT Group for Adolescents With ADHD : a R and omized Controlled Trial ; http:// clinical trials.gov/ ; NCT02172183 Abstract Background : Different treatment approaches aim ed at reducing attention-deficit/hyperactivity disorder ( ADHD ) core symptoms are available . However , factors such as intolerance , side-effects , lack of efficacy , high new technology costs , and placebo effect have spurred on an increasing interest in alternative or complementary treatment . Aim : The aim of this study is to explore efficacy of multimodal treatment consisting of st and ard stimulant medication ( methylpheni date ) and neurofeedback ( NF ) in combination , and to compare it with the single treatment in 6-month follow-up in ADHD children and adolescents . Methods : This r and omized controlled trial with 6-month follow-up comprised three treatment arms : multimodal treatment ( NF + MED ) , MED alone , and NF alone .  A total of 130 ADHD children/adolescents participated , and 62 % completed the study .  ADHD core symptoms were recorded pre-/post-treatment , using parents ’ and teachers ’ forms taken from Barkley ’s Defiant Children : A Clinician ’s Manual for Assessment and Parent Training , and a self-report question naire . Results : Significant ADHD core symptom improvements were reported 6 months after treatment completion by parents , teachers , and participants in all three groups , with marked improvement in inattention in all groups . However , no significant improvements in hyperactivity or academic performance were reported by teachers or self-reported by children/adolescents , respectively , in the three groups . Changes obtained with multimodal treatment at 6-month follow-up were comparable to those with single medication treatment , as reported by all participants . Conclusions : Multimodal treatment using combined stimulant medication and NF showed 6-month efficacy in ADHD treatment . More research is needed to explore whether multimodal treatment is suitable for ADHD children and adolescents who showed a poor response to single medication treatment , and for those who want to reduce the use of stimulant medication OBJECTIVE To test whether adoption of a collaborative consultative service model results in improved patient outcomes . DESIGN Twelve pediatric practice s were r and omly assigned to receive access to collaborative consultative services or to a control group . SETTING Community-based pediatric offices . PARTICIPANTS Fifty-two pediatricians and their 377 patients with attention-deficit/hyperactivity disorder ( ADHD ) . Intervention A collaborative consultative service promoting the use of titration trials and periodic monitoring during medication maintenance . Main Outcome Measure Physician practice behaviors and child ADHD symptomatology . RESULTS Using self-report of pediatricians , the collaborative consultative service increased the use of evidence -based practice s by pediatricians , but no difference in children 's ADHD symptomatology was observed between the groups . However , many pediatricians did not fully use the collaborative consultative services . Those children who actually received collaborative consultative services showed significant behavioral improvement compared with children not receiving these services . CONCLUSIONS When actually implemented by pediatricians , the collaborative consultative service appears to be an effective method for facilitating evidence -based treatment procedures for ADHD and use of these procedures appear to improve children 's outcomes . Barriers to implementation of collaborative consultative service in pediatric practice need to be further understood Background A r and omized and controlled clinical study was performed to evaluate the use of neurofeedback ( NF ) to treat  attention-deficit/hyperactivity disorder ( ADHD ) in children and adolescents . Methods The ADHD population was selected from an outpatient clinic for Child and Adolescent Mental Health in Norway . Ninety-one of the 275 children and adolescents ranging in age from 6 to 18 years ( 10.5 years ) participated in 30 sessions of an intensive NF program . The reinforcement contingency was based on the subjects ’ production of cortical beta1 activity ( 15–18 Hz ) . The ADHD participants were r and omized into three groups , with 30 in the NF group , 31 controls in a group that was given methylpheni date , and 30 in a group that received NF and methylpheni date .  ADHD core symptoms were reported by parents using the parent form of the Clinician ’s Manual for Assessment by Russell A. Barkley . Results Ninety-one children and adolescents were effectively r and omized by age , sex , intelligence and distribution of ADHD core symptoms . The parents reported significant effects of the treatments , but no significant differences between the treatment groups were observed . Conclusions NF was as effective as methylpheni date at treating the attentional and hyperactivity symptoms of ADHD , based on parental reports . Trial registration Current Controlled Trials BACKGROUND We wanted to study the effects of amphetamine on symptoms of attention-deficit hyperactivity disorder ( ADHD ) over a longer period than has been reported in previous studies of central stimulants in this condition . METHODS Sixty-two children , aged 6 to 11 years , meeting DSM-III-R symptom criteria for ADHD participated in a parallel-group design , r and omized , double-blind , placebo-controlled study of amphetamine treatment . Treatment was not restricted to children with " pure " ADHD , ie , some had comorbid diagnoses . In the amphetamine group , children received active treatment for 15 months . RESULTS Amphetamine was clearly superior to placebo in reducing inattention , hyperactivity , and other disruptive behavior problems and tended to lead to improved results on the Wechsler Intelligence Scale for Children -- Revised . Treatment failure rate was considerably lower and time to treatment failure was longer in the amphetamine group . Adverse effects were few and relatively mild . CONCLUSION The results of this long-term , placebo-controlled study of the central stimulant amphetamine in the treatment of ADHD indicate that there are remaining positive effects of the drug 15 months after starting treatment This study evaluates the effectiveness of cognitive behavioral therapy ( CBT ) in improving the home behavior of children with attention deficit hyperactivity disorder ( ADHD ) . Twenty-five boys ( age 7 to 13 ) with a diagnosis of ADHD were r and omized to a CBT or supportive therapy control group . Outcome measures included parent and teacher ratings of the child on the Behavior Problem Checklist-Attention Problem Subscale ( BPC-AP ) , and the Self-Control Rating Scale ( SCRS ) , parent ratings on the Modified Werry Weiss Activity Scale , and child ratings on the Piers Harris Self-Concept Scale and Matching Familiar Figures Task . Data were analyzed using a two-way analysis of variance for main effects . A significant improvement favoring CBT was found on the Werry Weiss Scale , which measures the parent 's perception of the child 's hyperactivity in the home , and the child 's rating of his/her self-esteem on the Piers Harris Self-Concept Scale . Other outcome measures did not demonstrate statistical differences . This research provides support for the use of CBT in children with ADHD .  CBT was found to improve the parent 's perception of the child 's hyperactivity in the home as well as the child 's self-esteem The objective of this study was to evaluate the efficacy of a multicomponent program for treating attention-deficit/hyperactivity disorder ( ADHD ) carried out by teachers in a classroom context . Dependent measures included neuropsychological tasks , behavioral rating scales for parents and teachers , direct observation of behavior in the classroom , and academic records of children with ADHD . Fifty children with ADHD participated in the study . The teachers of 29 of the 50 students  were trained in the use of behavior modification techniques , cognitive behavior strategies , and instructional management strategies . The other 21 students formed the  control group . Parents ' and teachers'ratings detected improvements in primary symptoms ( inattention — disorganization , hyperactivity — impulsivity ) and in behavioral difficulties usually associated with ADHD ( e.g. , antisocial behavior , psychopathological disorders , anxiety ) . Furthermore , the results showed increased academic scores , enhanced classroom behavioral observations , and improved teachers ' knowledge about the strategies directed toward responding to the children 's educational needs Attention deficit hyperactivity disorder ( ADHD ) is related to a deficiency of central catecholamines ( CA ) in cognitive , biochemical , and physical tests , and pharmaceutical intervention may have no effect if it is not accompanied by changes in the environment . The objective of our study was to test the hypothesis that central CA are responsible for the increase in speed reaction seen after physical activity ( PA ) and to measure the impact of high intensity PA on the sustained attention of 25 children diagnosed with ADHD consistent with the Disease Statistical Mental-IV ( DSM-IV ) criteria . It is possible that practicing sports assists in the management of the disorder . The children were divided between users ( US ) and non-users ( NUS ) of methylpheni date ( MTP ) , and the groups were compared to evaluate the effect of the drug on cognition after PA . Post-exercise performance on Conner ’s Continuous Performance Test-II ( CPT ) was not affected by MTP , we observed significant improvements in response time , and we saw normalization in the impulsivity and vigilance measures . These results suggest that the improvements in cognition after physical effort are not CA dependent . Additionally , our results suggest that  children ’s attention deficits can be minimized through PA irrespective of treatment with MTP . Additional studies are necessary to confirm that exercise mitigates the harmful symptoms of ADHD PURPOSE As adjuvant therapy for enhancing the effects of stimulants and thereby minimizing medication doses , we hypothesized that aerobic exercise might be an effective adjunctive therapy for enhancing the effects of methylpheni date on the clinical symptoms , cognitive function , and brain activity of adolescents with attention deficit hyperactivity disorder ( ADHD ) . METHODS Thirty-five adolescents with ADHD were r and omly assigned to one of two groups in a 1/1 ratio ; methylpheni date treatment + 6-wk exercise ( sports-ADHD ) or methylpheni date treatment + 6-wk education ( edu-ADHD ) . At baseline and after 6 wk of treatment , symptoms of ADHD , cognitive function , and brain activity were evaluated using the Dupaul attention deficit hyperactivity disorder rating scale -- Korean version ( K-ARS ) , the Wisconsin Card Sorting Test , and 3-T functional magnetic resonance imaging , respectively . RESULTS The K-ARS total score and perseverative errors in the sports-ADHD group decreased compared with those in the edu-ADHD group . After the 6-wk treatment period , the mean β value of the right frontal lobe in the sports-ADHD group increased compared with that in the edu-ADHD group . The mean β value of the right temporal lobe in the sports-ADHD group decreased . However , the mean β value of the right temporal lobe in the edu-ADHD group did not change . The change in activity within the right prefrontal cortex in all adolescents with ADHD was negatively correlated with the change in K-ARS scores and perseverative errors . CONCLUSIONS The current results indicate that aerobic exercise increased the effectiveness of methylpheni date on clinical symptoms , perseverative errors , and brain activity within the right frontal and temporal cortices in response to the Wisconsin card sorting test stimulation OBJECTIVE The purpose of this study was to estimate the prevalence and time trends in prescriptions of methylpheni date , dexamphetamine , and atomoxetine in children and adolescents , within three diagnostic groups : 1 ) autism spectrum disorder ( ASD ) , 2 ) attention-deficit/hyperactivity disorder ( ADHD ) , and 3 ) other psychiatric disorders . METHODS Data from six different national registers were used and merged to identify a cohort of all children and adolescents born in Denmark between 1990 and 2001 ( n=852,711 ) . Sociodemographic covariates on cohort members and their parents and lifetime prescriptions of methylpheni date , dexamphetamine , and atomoxetine were extracted from the registers . Prescriptions were also stratified by duration ( < 6 months . vs.≥ 6 months ) . RESULTS Sixteen percent of 9698 children and adolescents with ASD ( n=1577 ) , 61 % of 11,553 children and adolescents with ADHD ( n=7021 ) and 3 % of 48,468 children and adolescents with other psychiatric disorders ( n=1537 ) were treated with one or more ADHD medications . There was a significant increase in prescription rates of these medications for all three groups . From 2003 to 2010 , youth 6 - 13 years of age with ASD , ADHD , and other psychiatric disorders had 4.7-fold ( 4.4 - 4.9 ) , 6.3-fold ( 6.0 - 6.4 ) , and 5.5-fold ( 5.0 - 5.9 ) increases , respectively , in prescription rates of ADHD medications . CONCLUSION This is the largest study to date assessing stimulant treatment in children and adolescents with ASD , and is the first prospect i ve study quantifying the change over time in the prevalence of treatment with ADHD medications in a population -based national cohort of children and adolescents with ASD . The prevalence of stimulant treatment in youth with ASD of 16 % is consistent with earlier studies . The past decade has witnessed a clear and progressive increase in the prescription rates of medications typically used to treat ADHD in children and adolescents in Denmark . This increase is not limited to only those with ADHD , but includes others with neuropsychiatric disorders , including ASD . The risks and benefits of this practice await further study
The results revealed that findings are becoming increasingly nuanced with variations in levels of evidence related to ages of the children and characteristics of the specific treatment .
In addition , we focused our critique on generalization of treatment effects across setting s and time and on sample diversity ( with regard to ethnicity and levels of parent education ) in relation to the population .
Children of parents with higher levels of education than average appear to be overrepresented in the literature .
The purpose of this research was to up date the series of articles on evidence -based treatment for children and adolescents with attention deficit/hyperactivity disorder that have appeared in this journal ( Evans , Owens & Bunford , 2014 ; Pelham & Fabiano , 2008 ; Pelham , Wheeler , & Chronis , 1998 ) .
