Long-Term Follow-Up of Children with Mental Retardation/Borderline Intellectual Functioning and ADHD
Benjamin L. Handen Janine Janosky Sarah McAuliffe 《Journal of abnormal child psychology》1997,25(4):287-295
Fifty-two children (ages 7 to 14 years) with moderate mental retardation to borderline intellectual functioning were recontacted 12 to 65 months following participation in a double-blind, placebo-controlled trial of methylphenidate (MPH). Sixty-nine percent of subjects continued to be prescribed medication for behavior control at follow-up. While 72% of the sample evidenced improvement, over two-thirds continued to be rated at or above the 98th percentile on the Hyperactivity Index of the Parent Conners. In fact, 22% of subjects had received inpatient psychiatric treatment between the time of the initial MPH trial and follow-up. Finally, subjects with high initial ratings on the Parent Conners Conduct Problems scale were more likely to be suspended from school or receive inpatient psychiatric treatment than subjects with low initial ratings. The results suggested that children with ADHD and mental retardation or borderline intellectual functioning continued to exhibit significant symptoms associated with attention deficit hyperactivity disorder (ADHD) at follow-up and that early conduct problems were predictive of continuing behavioral difficulties. 相似文献

Frame-of-Reference Training: Overcoming the Effects of Organizational Citizenship Behavior on Performance Rating Accuracy 总被引:1,自引:0,他引:1

Frame-of-reference (FOR) training has been shown to increase rating accuracy. Studies suggest, however, that organizational citizenship behavior (OCB) can influence performance ratings insomuch as they are considered in the rating process. We examined the effects of OCB on the effectiveness of FOR training for improving performance rating accuracy. Results from 77 managers showed that OCB attenuates FOR training effectiveness because of rating inflation, unless the managers are trained to observe and evaluate the OCB. 相似文献

Evidence suggests that the NO/sGC/PKG pathway plays a key role in memory processing but the actual participation of this signaling cascade in the amygdala during memory consolidation remains unknown. Here, we show that when infused in the amygdala immediately after inhibitory avoidance training, but not later, the NO synthase inhibitor L-NNA hindered long-term memory retention without affecting locomotion, exploratory behavior, anxiety state or retrieval of the avoidance response. The amnesic effect of L-NNA was not state-dependent and was mimicked by the soluble guanylyl cyclase inhibitor LY83583 and the PKG inhibitor KT-5823. On the contrary, post-training intra-amygdala infusion of the NOS substrate L-Arg, the NO-releasing compound SNAP or the non-hydrolysable analog of cGMP 8Br-cGMP increased memory retention in a dose-dependent manner. Co-infusion of 8Br-cGMP reversed the amnesic effect of L-NNA and LY83583 but not that of KT-5823. Our data indicate that the NO-induced activation of PKG in the amygdala is a necessary step for consolidation of inhibitory avoidance memory. 相似文献

The role of catechol-O-methyltransferase (COMT) val158met in prefrontal cortical deficits associated with the liability to schizophrenia remains controversial. This study evaluated 464 healthy adult participants using three measures of executive functions in working memory: a 3-back version of the N-back continuous performance task (CPT) and two variants of the AX-CPT. The interpretability of N-back performance was confounded by possible generalized deficits, whereas the AX variants included internal controls for uncovering specific deficits. There was no relationship between the COMT genotype and N-back performance, whereas val/val individuals had a specific deficit on a dot-pattern version of the AX-CPT. In this case, a specific executive function known as context processing appeared to be compromised. These data suggest that the interpretability gained by including task manipulations to uncover specific deficits can enhance associations between cognitive and genetic levels of analysis. 相似文献

In this paper I distinguish three senses of could turn out/couldhave turned out in an attempt to elucidate how each is connected tothe notion of discovery and how each determines that a statement ofthe form `X could turn out P' (`X could have turned out P') is true.I argue that the actuality-oriented sense of could turn outbest captures what we ordinarily mean when we use could turnout or could have turned out in a nonevidential sense. 相似文献

People with autism have a number of reported deficits in object recognition and global processing. Is there a low-level spatial integration deficit associated with this? We measured spatial-form-coherence detection thresholds using a Glass stimulus in a field of random dots, and compared performance to a similar motion-coherence task. A coherent visual patch was depicted by dots separated by a rotational transformation in space (form) or space-time (motion). To measure parallel visual integration, stimuli were presented for only 250 ms. We compared detection thresholds for children with autism, children with Asperger syndrome, and a matched control group. Children with autism showed a significant form-coherence deficit and a significant motion-coherence deficit, while the performance of the children with Asperger syndrome did not differ significantly from that of controls on either task. 相似文献

Since the reauthorization of IDEA (1997), the use of functional assessments to examine factors that are related to students challenging behaviors has gained increasing attention in the literature. Over the past five years, several groups of investigators have conducted systematic analyses of the current status of the use of functional assessment in relation to students with or at risk for emotional/behavioral disorders (EBD). Their findings outline a number of critical, applied research issues for the field to consider. The purpose of this paper is to respond to a number of these issues by highlighting the relevance of structural analysis in addition to and in some cases in lieu of more traditional functional assessments. A brief review of current trends in the functional assessment research is presented as well as a rational for the use of structural analysis to examine the occurrence of appropriate behavior for students with EBD. Finally, illustrations of studies conducting structural analyses in classrooms settings are provided. 相似文献

The nosological status of borderline personality disorder as it relates to the bipolar disorder spectrum has been controversial. Studies have supported, in part, the validity of the bipolar spectrum by demonstrating that these patients, compared to patients with nonbipolar depression, are characterized by earlier age of onset of depression, recurrent depressive episodes, comorbid anxiety and substance use disorders and increased suicidality. However, all of these factors have likewise been found to distinguish depressed patients with and without borderline personality disorder. A family history of bipolar disorder is one of the few disorder specific validators. In the present study from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we compared the demographic and clinical characteristics of depressed patients with and without borderline personality disorder. We hypothesized that many of the factors used to validate the bipolar spectrum will also distinguish depressed patients with and without borderline personality disorder except, however, a family history of bipolar disorder. Two thousand nine hundred psychiatric outpatients at Rhode Island Hospital were evaluated with the Structured Clinical Interview for DSM-IV (SCID) and Structured Interview for DSM-IV Personality Disorders (SIDP-IV). Family history information regarding first-degree relatives was obtained from the patient using the Family History Research Diagnostic Criteria. One hundred and one patients with borderline personality disorder plus major depressive disorder were compared to 947 patients with major depressive disorder alone on the prevalence of bipolar disorder validators. Compared to depressed patients without borderline personality disorder, depressed patients with borderline personality disorder had a younger age of onset, more depressive episodes, a greater likelihood of experiencing atypical symptoms and had a higher prevalence of comorbid anxiety disorders, substance use disorders, and number of previous suicide attempts. The depressed patients with borderline personality disorder did not significantly differ from the patients without borderline personality disorder on morbid risk for bipolar disorder in first degree relatives. In addition, patients with a diagnosis of bipolar disorder had a significantly higher morbid risk of bipolar disorder in first degree relatives than the borderline personality disorder group. The findings indicate that many factors used to validate the bipolar spectrum are not disorder specific. These results raise questions about studies of the validity of the broad bipolar spectrum that do not assess borderline personality disorder. Our results do not support inclusion of borderline personality disorder as part of the bipolar spectrum. 相似文献
