With the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association. Diagnostic and statistical manual of mental disorders DSM-IV Fourth Edition-Text Revision. Author, Washington, DC. 2000) ahead, decisions will be made about the future of taxonomic conceptualizations. This study examined the factor structure of items from three internalizing disorders (Social Phobia, Generalized Anxiety Disorder, and Depression) on the Anxiety Disorders Interview Schedule for DSM-IV-Child Version (Silverman, W. K., & Albano, A. M. Anxiety disorders interview schedule for children for DSM-IV, child and parent versions. Psychological Corporation, San Antonio, 1996). Two-, three-, and four-factor models emerged in an exploratory factor analysis. Confirmatory factor analysis provided additional empirical support for the four-factor model over the two- or three-factor models. Implications for the structure of the DSM-V taxonomy in children and adolescents are discussed.  相似文献

A study of object naming in 202 children, aged 5–11 years, demonstrated that varying the stimulus context affected the level of response accuracy. From age 6 to 10, completing a sentence with a noun (auditory) yielded the lowest error scores, naming objects upon hearing a definition (also auditory) produced most errors, while responding with names to pictured objects was of intermediate difficulty. This is the same order of object naming difficulty found in adult aphasic patients. Children older than 10 do not appear to be affected by stimulus context in their object naming. Results are discussed in terms of the relative syntactic difficulty of the two auditory conditions, the unexpected sex differences, and the “aphaseoid” naming errors of children.  相似文献

A teacher scale based on DSM-III-R diagnostic criteria for attention deficit hyperactivity disorder (ADHD) was developed for the behavioral assessment of children in Brazil. A total of 2, 082 children (782 males and 1,300 females) with a mean age of 11.2 years who were attending a public school in the greater Rio de Janeiro area were the subjects of this study. Two factors (Hyperactivity-Impulsivity and Inattention) were extracted from a principal-factor analysis conducted on the data, and the factor structure of the scale was found to be stable. Ratings of boys were higher than ratings of girls, and younger children had higher ratings than older children for both factors. Test-retest reliability for each item of the scale ranged from .56 to .70. The data are discussed in view of current controversies in the factor structure of teacher ratings of DSM-III-R ADHD symptoms.This research was supported by FINEP (42.88.0138.00) and FUNPENE.

Maple, a computer algebra system, is employed in introductory statistics courses to promote conceptual learning by students of statistical principles without direct use of mathematics. Maple’s symbolic computation, graphic display, and animation capabilities support an integrated set of procedures for active study of sampling distributions and concepts related to samples, populations, and statistical decision making, error, and power. Students select parameter values for one-line commands and examine the effects of alternatives on computer-generated graphical representations of distributions. The 20 procedures written to support active student exploration of basic statistical concepts are described, and examples of exercises to support their use are provided.  相似文献

In both psychiatric and substance-abuse services, clinicians have been concerned with the introduction of automated assessments and with their clients’ reactions toward those assessments. The positive reactions of psychiatric clients have been well documented, but little has been known about substance-abusing clients’ impressions of automated assessments. The impact of automated assessment on clients seeking substance-abuse services was evaluated and compared with a previously analyzed sample of clients seeking mental health services. On the whole, both groups responded similarly and positively to automated assessments. Factor analyses revealed three underlying dimensions in client attitudes toward automated assessment,Completeness and satisfaction,Ease of use and enjoyment, andNegative attitudes. In addition, statistically, though not clinically, significant differences in attitudes were found between various demographic groups. Overall, the results support the use of automated assessments with individuals seeking either substance-abuse or mental-health services.  相似文献

This study examined the factorial structure and validity of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a European forensic context. A random sample of 257 criminal offenders from the Lithuanian prison population were administered the PCL:SV (Hart et al. 1995). The pattern of validity coefficients in this sample was comparable to other North American and non-North American samples. Several theoretical factorial structures for the PCL:SV were tested and compared. The two-factor model was not supported, while three- and four-factor models provided an acceptable fit to Lithuanian data. The four-factor model showed significantly better fit compared to the two-factor model. Correlations between PCL:SV factors and demographic variables confirm construct validity. However in the four-factor model, when controlling for correlations of the remaining three factors, only the Antisocial factor significantly correlated with variables related to criminal activity. It was concluded that the overall results of the PCL:SV in a male sample of Lithuanian offenders support cross-cultural generalizability of the construct of psychopathy as measured by the PCL:SV.  相似文献

Twenty-nine infants exposed in utero to methadone and 37 comparison infants were examined on the Neonatal Behavioral Assessment Scale at early and late neonatal ages. All infants were full-term at birth, over 2500 g, and not yet circumcised at the early assessment. None of the methadone-exposed infants were breast-fed or were being treated pharmacologically for withdrawal. During the first week of life, methadone-exposed neonates differed from comparison ones in motoric behavior. Relative to comparison-group infants, they were jerkier and more tremulous, tense, active, and better able to put hand in mouth. By the end of the first month these differences diminished, although there was still a tendency for the methadone-exposed infants to have elevated body tonus. Neither perinatal complications, birth weight, nor sex of infant could explain the early neonatal differences between the methadone and comparison groups. Past the early stage of acute withdrawal, neonates exposed prenatally to methadone behave not unlike their nonexposed peers.  相似文献

Abstract

Work meaning patterns combine dimensions such as work centrality, expressive versus economic work goals, and entitlement versus obligation societal norms into a holistic picture of the evolution over time of the meaning of work. Data from a longitudinal study in eight countries are used to establish major work meaning patterns and to study their stability during early career paths. Further, some potential determinants of these work meaning patterns are analysed and their consequences for later careers are considered. Statistical analyses include: cluster analysis, multiple discriminant analysis, analysis of covariance combined with multiple classification analysis, analysis of variance, and chi-square analysis. Five cross-national work meaning patterns are identified for machine operators in their third year in the labour market. One-third of the sample had remained in the same work meaning pattern for 2 years, while two-thirds had changed their work pattern. Respondents' age, country, prior work environment, and prior work socialization behaviours and outcomes have an impact on work meanings held 2 years later. In addition the respondent's work meaning pattern allows subsequent career enhancing strategies and effort expenditure at the job to be predicted.  相似文献

The authors analyzed the suprasegmental (temporary) vocal profiles of 19 young men (not married) during their seductive interaction with 19 young women (not married) whom they had not known previously. The aim of the research was to verify the specificity, the sequential temporal stream, and the efficacy of the acoustical features of the seducer's voice during seductive interaction. In an ecological laboratory situation, the male participants were asked to meet their female partners. Participant-by-participant analysis showed that the male seductive voice is characterized by strong variations during the course of the seductive sequence. At the beginning of the sequence it had a higher pitch and an elevated intensity, as well as a faster rate of articulation than it did during normal speech (the exhibition voice). In the following phases it became gradually lower, weaker, and warmer (the self-disclosure voice). The modulation and variability of the vocal profiles during the seductive interaction were significantly stressed in the 9 successful seducers (those who succeeded in arranging a subsequent meeting with the partner), compared with the 10 unsuccessful seducers. The results have been interpreted as an ability to perform an effective local management of seductive communication.  相似文献
