ABSTRACT
Objective@#Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a “morbid condition” which also needs medical attention. @*Methods@#The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. @*Results@#For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. @*Conclusion@#Our present findings supported the suggestion of subthreshold ADHD as “morbid condition,” which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.
ABSTRACT
Family environment plays an important part of the occurrence,development and outcome of attention-deficit/hyperactivity disorder (ADHD).Family and parenting interventions focus on the inter environment,aiming at forming an effective behavioral management,a better communication strategy,which will be conductive for child's symptoms as well as functions.Parents'emotion and self-efficacy as well as family functioning will be affected also.Common family and parenting skills include parent training and systematic family therapy,which respectively focus on behavior management and the whole family in view of system.The Multimodal Treatment Study of Children with ADHD (MTA) may have potential effects compared with single medical treatment and behavioral treatment.In China,parent training and structural family therapy have been proved to be effective.However,further consideration and experiments are necessary,especially on the long-time ending and individual management.
ABSTRACT
Objective To explore the executive function profiles in adults with attention deficit hyperactivity disorder(ADHD)in a Chinese sample population. Methods We identified 68 outpatients fulfilling the diagnostic criteria for ADHD according to the Diagnostic and Statistical Manual of Mental Disorders-IV(DSM-IV)and 74 normal adults.All subjects completed clinical interview, Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) and Cambridge Neuropsychological Test Automated Battery (CANTAB). Results ADHD group had higher scores in all factors of BRIEF-A questionnaire compared with normal control (P<0.01). ADHD group had a higher score in SWM strategy score [(30.84±5.58)vs.(28.80±5.85), t=2.056,P=0.042]compared with control group. Compared with control group, ADHD group had a lower score in RVP total hits [37(33,41.75) vs.3(37,48), Z=-3.184,P<0.01]. Total correct rejections[(508(497.5,518)vs. 516(503,529.5),Z=-2.229,P=0.0260)]were significantly lower,while RVP total misses were significantly higher [(17 (12.25,21)vs.12(7,20),Z=2.293,P=0.022)].ADHD-RS-IV attention deficit score was positively correlated with SWM strategy while RVP total misses were negatively correlated with RVP total hits and RVP correct rejections.Working memory score in BRIEF-A was significantly correlated with the SWM strategy,RVP total hits, RVP total correct rejections and RVP probable of hit as well as RVP total misses. Conclusion Adults with ADHD have executive functioning deficits which is correlated with ADHD core symptoms.
