Informant-related determinants of item attenuation, that is, the drop-off in symptom endorsement rates at retest, were examined in an enriched community subsample of 245 parent–child pairs drawn from the National Institute of Mental Health Methods for Epidemiology of Child and Adolescent Mental Disorders Study. Youngsters and their parents were interviewed with the Diagnostic Interview Schedule for Children (Version 2.3; DISC-2.3) on two occasions with a mean test–retest interval of 12 days. Item attenuation rates were high for both informants, with adults failing to confirm 42% and children 58% of baseline responses at retest. Stepwise regressions revealed that item attenuation at DISC-P retest was higher for adult informants who were younger, and who reported on older and less impaired children. On the DISC-C, attenuation was higher for children who were less impaired, rated as doing worse in school, and who had a longer test–retest interval. These results are broadly consistent with past studies examining the determinants of attenuation and test–retest reliability and have implications for the design and use of structured diagnostic instruments. 相似文献

Secondary analyses of the data from the Puerto Rico Child Psychiatry Epidemiologic Study were undertaken to provide information on the comorbidity patterns of ADHD. A high level of comorbidity was found among ADHD and other diagnostic categories, particularly the conduct/oppositional group. Comorbidity was associated with level of impairment and with service utilization. 相似文献

Two release from proactive inhibition experiments were conducted, in which orienting tasks were employed to direct subjects' attention to particular features of words. Experiment 1 employed two such tasks which emphasized either semantic or nonsemantic features, while both orienting tasks in Experiment 2 directed attention to semantic features of words. Although significant release was obtained with a change in task in these experiments, the level was considerably lower in Experiment 2 than in Experiment 1. The data were interpreted in terms of a theoretical orientation that emphasizes item differentiation as a major determinant of retrieval probability. It was argued that the degree of differentiation depends to some extent on the specific tasks employed and the extent to which they direct attention to different word features. 相似文献

This paper describes a computer-based system for the on-line experimental use of musical stimuli. The system is in two sections. The first records in digital form two successive monophonie keyboard performances and combines them into a two-part musical stimulus consisting of bass and treble melodic lines. This musical stimulus can be modified in one or more ways by means of an editing program. The second part of the system presents the modified stimulus to the subject and records his reaction time to particular target notes. The system can be expanded to allow the merging of a larger number of melodic lines into a single polyphonic form or can be modified to produce precisely controlled two-channel tonal stimuli. 相似文献

While research on observational learning has typically employed visual models of correct performance, the characteristics of perceptual systems support the suggestion that an auditory model may be more effective in developing a cognitive representation of tasks for which timing is essential. Therefore, it was the purpose of this study to compare the relative effectiveness of auditory and visual models in the acquisition of a timing task. Subjects were provided with an auditory model, a visual model, a combined auditory and visual model, or no model of correct performance. There were significant main effects of groups and trials during acquisition. While performance of all groups improved during acquisition, the audio and audiovisual groups had generally better performance. The same effects were significant on immediate transfer, again reflecting the superior performance of the two auditory model groups. The results suggest an important role for audition in the development of a cognitive representation of movement timing. 相似文献

The relationship between marital discord and any DISC-2.1/DSM-III-R child psychiatric diagnosis was explored. Interview data from a community sample of 90 parent/child pairs and a clinic sample of 37 parent/child pairs were analysed. The data were collected at Columbia University/the New York State Psychiatric Institute as part of the pilot project of a multi-site methodological study. Rates of marital discord and DISC diagnoses were found higher in the clinic sample than in the community sample. The association between marital discord and any diagnosis remained significant when other risk and protective factors were controlled. Policy implications and recommendations for future research strategies suggested by the current exploratory study were discussed. 相似文献

Trust is a critical component of research: trust in the work of co-workers and colleagues within the scientific community;
trust in the work of research scientists by the non-research community. A wide range of factors, including internally and
externally generated pressures and practical and personal limitations, affect the research process. The extent to which these
factors are understood and appreciated influence the development of trust in scientific research findings. 相似文献
