Programming stimuli in matching to sample

In these investigations, a “teaching machine” was used to train pre-school and first-grade children in a series of progressively difficult discrimination tasks, leading up to matching to sample. Such training was much more efficient than training in the final discrimination alone. The errors the subjects made were found to be a functon both of the differences between consecutive discriminations (the “size of the steps” in the program) and the length of training on each discrimination. Theoretical and practical implications of these findings are discussed.     

Evaluation of Indicated Preventive Intervention (Secondary Prevention) Mental Health Programs for Children and Adolescents

Evaluated the outcomes of 130 indicated preventive interventions (secondary prevention) mental health programs for children and adolescents that seek to identify early signs of maladjustment and to intervene before full-blown disorders develop. Results indicate such programs significantly reduce problems and significantly increase competencies. In particular, behavioral and cognitive-behavior programs for children with subclinical disorders (mean ESs in the 0.50s) appear as effective as psychotherapy for children with established problems and more effective than attempts to prevent adolescent smoking, alcohol use, and delinquency. In practical terms, the average participant receiving behavioral or cognitive-behavior intervention surpasses the performance of approximately 70% of those in a control group. Of particular interest was the high mean effect (0.72) achieved by programs targeting incipient externalizing problems which are customarily the least amenable to change via traditional psychotherapeutic efforts when they reach clinical levels. Priorities for future research include greater specification of intervention procedures, assessment of treatment implementation, more follow-up studies, and identifying how different participants respond to early intervention.     

Effects of a verbal warning and overcorrection on stereotyped and appropriate behaviors

In Experiment I, the effects of a verbal warning, such as is used in Overcorrection, delivered contingently on the stereotyped mouthing behavior of two autistic/retarded children were examined. A multiple baseline design across subjects was used. The results indicated that the mouthing of one child was reduced to a nearzero level and mouthing of the second child was moderately reduced. Appropriate toy play and inappropriate object manipulation failed to show systematic changes in occurrence when mouthing was decelerated. In Experiment II, the same subjects and experimental design were used to assess the effects of a positive practice Overcorrection procedure delivered contingent on mouthing behavior. Overcorrection reduced the mouthing of both subjects. There were no systematic changes in inappropriate object manipulation but one subject did demonstrate an increased occurrence of appropriate toy play. In addition, this subject often engaged in aggressive/escape behaviors during Overcorrection, suggesting that the procedure was aversive to him.     

Parent behavioral training: An analysis of the relationship among multiple outcome measures

The purpose of the present study was to examine the relationship among three types of outcome measures that have been employed to evaluate parent behavioral training: observational data collected by independent observers, parent-collected data, and parent-completed questionnaires. Previous research suggests that all three measures yield positive outcome data; however, a correlational analysis has not been performed to determine if the subjects who demonstrate the largest (smallest) change on one measure demonstrate the largest (smallest) change on the other measures. The present study undertook such a correlational analysis. Subjects were 20 young clinic-referred children and their mothers. Treatment consisted of a standardized parent training program to modifly child noncompliance. All three outcome measures (observational data, parent-collected data, and questionnaire data) indicated that therapy was effective. A correlational analysis performed on the outcome measures indicated a number of significant relationships for dependent variables withinthe observational data and withinthe questionnaire data; however, there were no significant relationships acrossthe three outcome measures. Although different outcome measures may yield similar conclusions about the effectiveness of parent behavioral training, the results suggest that any one subject, relative to other subjects, does not demonstrate uniform degrees of change across the three outcome measures. Explanations for the findings, as well as their implications, are discussed.This research was supported by NIMH grant MH-28859-01.     

Anxiety as a Predictor and Outcome Variable in the Multimodal Treatment Study of Children with ADHD (MTA)

Initial moderator analyses in the Multimodal Treatment Study of Children with ADHD (MTA) suggested that child anxiety ascertained by parent report on the Diagnostic Interview Schedule for Children 2.3 (DISC Anxiety) differentially moderated the outcome of treatment. Left unanswered were questions regarding the nature of DISC Anxiety, the impact of comorbid conduct problems on the moderating effect of DISC Anxiety, and the clinical significance of DISC Anxiety as a moderator of treatment outcome. Thirty-three percent of MTA subjects met DSM-III-R criteria for an anxiety disorder excluding simple phobias. Of these, two-thirds also met DSM-III-R criteria for comorbid oppositional-defiant or conduct disorder whereas one-third did not, yielding an odds ratio of approximately two for DISC Anxiety, given conduct problems. In this context, exploratory analyses of baseline data suggest that DISC Anxiety may reflect parental attributions regarding child negative affectivity and associated behavior problems (unlike fearfulness), particularly in the area of social interactions, another core component of anxiety that is more typically associated with phobic symptoms. Analyses using hierarchical linear modeling (HLM) indicate that the moderating effect of DISC Anxiety continues to favor the inclusion of psychosocial treatment for anxious ADHD children irrespective of the presence or absence of comorbid conduct problems. This effect, which is clinically meaningful, is confined primarily to parent-reported outcomes involving disruptive behavior, internalizing symptoms, and inattention; and is generally stronger for combined than unimodal treatment. Contravening earlier studies, no adverse effect of anxiety on medication response for core ADHD or other outcomes in anxious or nonanxious ADHD children was demonstrated. When treating ADHD, it is important to search for comorbid anxiety and negative affectivity and to adjust treatment strategies accordingly.

Relationships between worry, psychotic experiences and emotional distress in patients with schizophrenia spectrum diagnoses and comparisons with anxious and non-patient groups

BACKGROUND: This study tests the hypothesis that worry is associated with psychotic experiences and examines whether worry would contribute significantly to emotional response independently of the intensity of psychotic experiences. This study also explores differences in worry between patients with a diagnosis of a schizophrenia spectrum disorder, patients with anxiety disorders and non-patients. METHOD: Fifty-one patients with psychotic diagnoses, 40 patients with anxiety disorders and 60 non-patients were assessed on measures of psychotic experiences, cognitive components of anxiety and depression. RESULTS: Dimensions of worry were associated with dimensions of delusional ideation and with psychotic experiences and social worry predicted emotional responses over and above the intensity of psychotic experiences. Both clinical groups had significantly higher levels of worry in comparison with non-patients. CONCLUSIONS: These findings suggest that worry may be implicated in psychotic experiences and that people with psychotic diagnoses experience high levels of worry. The clinical implications of the findings are also discussed.
