Reliability of diagnosis in older psychiatric patients using the structured clinical interview for DSM-III-R

We conducted one of the few studies that has examined the reliability of the Structured Clinical Interview for DSM-III-R Axis I (SCID-I) with a mixed inpatient and outpatient population of adults 55 years old and over (range, 56–84 years; mean, 67.33 years). All SCID interviews were videotaped or audiotaped and were administered by Master's-level clinicians working toward their doctorate degrees in clinical psychology. Interrater reliability estimates (kappa and percentage agreement) were calculated for current major depressive episode (47% base rate) and the broad diagnostic categories of anxiety disorders (15% base rate) and somatoform disorders (12% base rate). Kappa values were .70, .77, and 1.0. Respective percentage agreement was 85% for major depression, 94% for anxiety disorders, and 100% for somatoform disorders. Overall percentage agreement was 91%. We conclude that the SCID-I can be effectively administered by relatively inexperienced clinicians to diagnose older psychiatric patients reliably. Directions that future research might take are offered.     

Accounting for nonlinear utility functions in composite measures of productivity and performance

Composite measures of productivity and performance combine different indicators of work activities into a single index. The term nonlinearities refers to the phenomenon that the relationship between the scores on an indicator of productivity and the value of that level of the indicator to the organization is not always linear. For example, more is not always better. This research evaluated whether accounting for such nonlinear relationships in productivity measures adds new information to the composite measures. Data from five organizations showed that the correlations between a composite measure which includes nonlinear relationships and one which does not were very high, but treatment effect sizes and decisions resulting from the two measurement systems were substantially different. It was concluded that inclusion of nonlinearities added important information to composite measures of productivity and that accounting for nonlinearities should result in more valid composites. Applications of this issue for other topics such as performance appraisal and promotions were discussed.     

Sex differences in the relationship of height to children's actual and attributed social and cognitive competencies

In three studies, the relationship of children's height to both (a) adults' attributions regarding the children and (b) preschoolers' social and cognitive competencies were examined. Sex differences were consistent with stereotypic conceptions. In the first two studies, mothers of preschool children rated photographs of toddlers varying in height on a variety of social and cognitive abilities. The mothers also assigned punishment to the children for hypothetical transgressions. In Experiment 1, mothers rated the large boys as more competent than the average-sized and small boys (even when effects of mothers' perceptions of the children's ages were covaried). In Experiment 2, involving female stimuli, mothers rated small girls as being less able (especially less independent) than average-sized or tall girls. While the effect of height on mothers' attributions was still evident when the effects of perceived age of the children were covaried, the pattern of results was less clear. Mothers assigned more punishment to tall girls (but not tall boys) than to small girls regardless of perceptions of age. In Experiment 3, height was associated with boys', but not girls', competence on tasks of logical ability and boys' sociometric nominations of whom they prefer to play with (significant for girls, marginally significant for boys). Height was not highly correlated with peers' perceptions of competence. The implications of the research for the socialization process are discussed.The authors wish to express their gratitude to the parents, teachers, and children at the Child Study Laboratory, Students' Child Center, Palo Alto Preschools, and Tempe Preschool. The authors would also like to thank Michael Gunzelman, Michelle White, Julie Mankowski, Marsha Kaplan, and Melissa Rook for their able assistance in data collection.     

So-called slow posterior activity in the EEG and the sensori-motor reaction time. Results of re-examinations made after 5 years

Six persons showing what is called slow posterior activity (4/s rhythm) in the electroencephalogram were reexamined after a period of five years. Sensorimotor reaction times were recorded in addition to the electroencephalogram which was analyzed for the frequency of LPA and for the degree of stability of time dependence. The frequency and distinctness of LPA were found to be stable after five years (r = 0.09 and 0.82, respectively; p less than 0.001), whereas the alpha rhythmus of the subjects had undergone considerable changes (r = 0.34; p greater than 0.05). The extension of reaction times to be observed under the influence of LPA was also seen to remain constant (r = 0.79; p less than 0.05). Accordingly, LPA proved an extremely stable characteristic which did not show any substantial variations in the course of five years.     

Localization of rhythmic activity around 4/s

The results of the studies carried out in four carriers of characteristics are presented under localistic aspects proceeding from the different local distribution of rhythmized activity around 4/s with unipopular and bipolar lead technique. A hypothesis of the origin of the activity is presented which would be in agreement with its distribution characteristics and reactivity.     

Useful Field of View and Other Neurocognitive Indicators of Crash Risk in Older Adults

Older adults represent a rapidly growing segment of the driving population. Although most older drivers are safe, research has shown that this group has more crashes per mile driven than most other age groups. The purpose of the present investigation was to examine the utility of a set of commonly used neuropsychological/cognitive tests in comparison to a newer measure of visual attention (Useful Field of View; UFOV®) in predicting state-recorded, at-fault crashes over the previous five years in a group of older adult drivers. Participants (N = 239) completed tests of mental status, visual attention, memory, and UFOV®. Results show that among all cognitive tests administered, UFOV® was most strongly related to crash involvement, with high levels of sensitivity (86.3%) and specificity (84.3%) at the standard cutoff score of 40% reduction. Practical implications for the assessment of crash risk are discussed.
