OBJECTIVE To determine response of low-IQ children with attention deficit hyperactivity disorder (ADHD) symptoms to methylphenidate (MPH). METHODS An aggregated analysis was conducted in 90 children with low IQ who received the same dose regimen of MPH in three independent, placebo-controlled studies. Active drug and placebo were given from 2 to 4 weeks(More)
Subjective quality of life is the individual's rating of his or her satisfaction with various domains of everyday living. Given the similarity of this construct with anhedonia due to depression, efforts to establish its construct validity vis-a-vis other psychiatric variables must partial out the influence of depression on subjective quality of life.(More)
The study examined Symptom Validity Test (SVT) performance in a sample of military service members on active orders as a function of evaluation context. Service members were assessed in the context of either a pending disability evaluation (Medical Evaluation Board; MEB) or a non-MEB/clinical evaluation. Overall, 41.8% of the sample failed the Word Memory(More)
The Nisonger Child Behavior Rating Form (NCBRF) has been used in several large studies of risperidone in children with low IQs (36-84) and disruptive behavior disorders (conduct disorder and oppositional defiant disorder). We wanted to develop a companion instrument for assessing 'typically developing' children and adolescents. In this study, we modified(More)
The construct validity was examined of two measures of social cognition in schizophrenia: (1) a measure of differential deficit in concrete versus abstract social cue perception and (2) a measure of differential deficit in concrete versus abstract situational feature recognition. A significant relationship between the two difference scores would be expected(More)
Research has shown that schizophrenia patients are less able to identify a situation's abstract features (goals) than its concrete features (actions). However, it has been unclear whether this differential deficit represents a cognitive dysfunction or a lack of familiarity with many situations because of impoverished social experiences. Twenty-nine(More)
The authors report an analysis of the reliability and validity of the Needs and Resources Assessment, an interview instrument that measures patients' needs and resources in 13 domains of functioning and rates patients' overall satisfaction with each domain and the importance of each need. Internal consistency of the instrument's four subscales-- needs,(More)
Proponents of psychiatric rehabilitation believe that active patient participation in rehabilitation planning is essential. Participation assumes, however, that severely mentally ill patients can reliably report their needs. Unfortunately, reliably responding to a needs assessment may be diminished by cognitive deficits that are associated with psychosis(More)
Twenty children with attention deficit hyperactivity disorder (ADHD) and low IQs, who participated in a drug study, were followed up 4.5 years later, when their ages averaged 12.4 years (range: 8-20 years: SD = 2.78). Participants were assessed by their parents and teachers on the Aberrant Behavior Checklist-Community (ABC; Aman & Singh, 1994), on the Child(More)
This brief report sought to evaluate the classification statistics of the Advanced Clinical Solutions (ACS) embedded measures of symptom validity in relation to the Word Memory Test (WMT), a well-established standalone measure of effort in a sample of active duty military service members with a history of mild traumatic brain injury. Results demonstrated(More)
