Psychological disturbance in children with physical disabilities: Continuity and change in a 5-year follow-up

This study measures continuity in behavioral disturbance over a 5-year period among 255 children with physical disabilities who were 6 to 18 years old at first assessment. The pattern of the results differed from that reported previously for a sample of the general population of children. Disabled children showed little stability in aggression, an area in which stability over time had been consistently reported for the general child population. Furthermore, important differences were observed between children with cystic fibrosis and children with cerebral palsy, myelodysplasia, or multiple physical handicaps, all conditions involving brain abnormality. Children with cystic fibrosis followed the trend toward better adjustment seen among the general population of children. In contrast, among children with conditions involving the brain, the majority of those who had been classified as psychologically severely impaired remained at this level of impairment 5 years later. In two behavioral domains, Mentation Problems and Isolation, children with conditions involving the brain maintained, on the average, the same markedly high score they had initially. Among children with physical conditions involving the brain, Mentation Problems and Isolation signify persistent problems that do not subside as the children mature.This study was supported by NIH grant No. HD-16821, by Research Scientist Development Award No. MH-00380 from NIMH, and by grants from the Cleveland Foundation and the Charles S.

The childhood experiences of psychopaths: a retrospective study of familial and societal factors.

We compared the childhood experiences of criminal psychopaths with those of criminal nonpsychopaths, to examine whether differences in either the type or intensity of adverse experience in childhood could be identified. One hundred and five prisoners, 50 psychopaths, and 55 nonpsychopaths were assessed with the Psychopathy Checklist-Revised (PCL-R) and Childhood Experience of Care and Abuse (CECA) semistructured interviews. Both assessment measures have been demonstrated to be reliable and valid instruments. File information from both adult and child services provided corroborative material. Factor analysis of the childhood experience variables revealed two distinct factors, familial and societal, both of which were highly correlated with adult psychopathy scores. These findings suggest that the experiences psychopaths have in childhood influence adult outcome.     

Cross-Cultural Supervision in Marriage and Family Therapy

The purpose of this study was to gain an understanding of the various cultural factors that influence the supervisor-trainee relationship when at least one of these individuals is a member of an ethnic minority group in the United States. Marriage and Family Therapy supervisors and students were asked to compare and contrast their experiences working with ethnic minority and white persons. Findings indicate that both supervisors and students express great value in cross-cultural supervisory experiences, but report that these opportunities are very limited.     

Infant cry as a graded signal: Experimental modifications of durations of pauses and expiratory sounds alter mothers' perceptions

The purpose of this study was to examine experimentally the effects of the temporal structure of infant crying on mothers' perceptions. Eighteen mothers of young infants rated variations of a 10-sec cry in which durations of all expiratory sounds and pauses were digitally lengthened and shortened by 50%. Results showed a general monotonic effect in which cries with increasingly shorter pauses were perceived to be more arousing, aversive, informative, and rough. Similarly, cries with short expirations were perceived to be more rhythmic and rough than cries with long expirations. The strength of the monotonic effect for pause duration on ratings of urgency interacted with the duration of expiratory sounds such that the combination of short pauses and short expirations created the greatest perceived urgency. This study replicates and extends previous findings which show that gradations in acoustic features of crying are associated with gradations in the intensity of adults' perceptions.     

Computer-based job simulation: A complementary approach to organizational research

This paper reviews current applications of computer-based job simulation procedures in the study of organizational phenomenon. It then presents a study in which a new approach to modeling employee turnover is examined in the context of a computer-based job simulation. The simulation technology allows the researcher to examine formally the relationships between critical organizational variables. It provides a realistic and engaging yetcontrollable flow of events to the participant, and represents a useful complementary approach to traditional organizational field studies.     

A Monte Carlo study of the Hoyt reliability coefficient in the Bower-Trabasso model

Monte Carlo procedures are used to study the sampling distribution of the Hoyt reliability coefficient. Estimates of mean, variance, and skewness are made for the case of the Bower-Trabasso concept identification model. Given the Bower-Trabasso assumptions, the Hoyt coefficient of a particular concept identification experiment is shown to be statistically unlikely.
