The influence of a videotape, shown in a hospital admitting room, on patients' state anxiety and concerns about hospitalization was assessed in a preliminary study. For both state anxiety and specific concerns regarding hospitalization the pretest scores on each variable accounted for the preponderance of the variance in the posttest scores. In both instances, the intervention and the interaction of the intervention with the pretest scores accounted for less than 1% of variance in the outcome. While finding small effects to be significant for such a small sample (N = 93) is unlikely, the sample size was adequate to detect medium to large effects. More important was the fact that 73.33% of the videotape intervention group indicated that they did not watch the video, which leads us to the conclusion that this intervention as tested is not worthwhile.  相似文献

Studies that compare objective data on communication activity to data provided in verbal reports have indicated that verbal report data are not as accurate as one might hope. Researchers of communication have used verbal reports as their primary source of data because it presents a cheap and easy way to collect the data. This paper presents an easy alternative involving the study ofelectronic communication: a method that allows the collection of objective information on electronic communication, thus avoiding the problems associated with self-reports. The paper reviews the available literature on the accuracy of self-reports of communication, presents the instrument used to collect the objective electronic communication data, and discusses some of the difficulties and limitations encountered in implementing a study using the instrument.  相似文献

There has been interest in recent years in the relationship between marital distress and psychopathology. It has been rare, however, for investigators to follow patients after their release from the hospital and observe the course of their marital relationships. The present study included patients meeting criteria for three DSM III DISORDERS (MAjor depressive, bipolar, and schizophrenic) and a normal control sample, all of whom are participants in an ongoing longitudinal study of children at risk for psychopathology (Stony Brook High-Risk Project; Weintraub & Neale, 1984). Marital Adjustment Test (MAT; Locke & Wallace, 1959) scores were collected on patients at entry into the project (Phase I) and at a three year follow-up (Phase II). Course of marriage was defined as negative if the couple's marital adjustment was rated as poor at Phase II or resulted in divorce or separation at Phase II. It was found that only the depressed group differed from the normal group in having significantly worse course of marital relationship; 84% of the depressive couples showed a “negative” course of marital change over time. However, all three patient groups had significantly higher rates of divorce by Phase II. MAT scores at Phase I successfully predicted course of marital relationship for all diagnostic groups. Implications for aftercare of psychiatric inpatients are discussed.  相似文献

Several aspects of gender concept development were investigated in 60 children of mixed socioeconomic background ranging in age from 3 to 6 years. Tasks were designed to assess gender constancy, knowledge of sex stereotypes, differential memory and preference for sex-typed material, and gender categorization. Cognitive maturity was assessed with a conservation task and total recall on a memory task. Performance improved linearly with age on the gender concepts, individual children of both sexes learned the gender concepts in the same sequence, and cognitive maturity measures were positively related to performance on the gender concept tasks.This research was supported by grants from the Graduate School and the Women's Studes Program, Indiana University. An earlier report of this research was presented at the meeting of the American Psychological Association, San Francisco, August 1977. The author thanks John E. Bates and Candace Schau for their advice and help throughout the project.  相似文献

Two groups of eight Ss each and one group of seven Ss were exposed to optical tilts (T) of 50, 40, 30, 20, and 10 deg in succession. Exposure time at each tilt was 3, 15, and 27 min in Groups 1, 2, and 3, respectively. Trend analyses of the functions relating level of adaptation to T showed significant quadratic components for Group 1, quadratic and linear components for Group 2, and only linear components for Group 3. These results were consistent with derivations from a memory-comparator model of perceptual adaptation.  相似文献

The paper is an attempt to review the basis for the claim that physicians have a professional obligation to treat AIDS patients. Considered are the historical record, two professional codes of ethics, and several recent articles. The paper concludes that the arguments considered, which attempt to support the claim that physicians have an obligation to treat, fail. It is suggested, rather, that common humanity, which physicians share with those who suffer from AIDS, ought to be the basis for engaging in the care of AIDS patients.  相似文献

Content analysis: a comparison of manual and computerized systems   总被引:5,自引:0,他引:5  
Computerized content analysis is a technique for classifying texts. In personality research it has been used to make inferences about psychological states and traits of the speaker or writer. Whereas computerized techniques have been increasing in both sophistication and ease of use, questions remain regarding their validity compared to hand-scored scales. In this study, we compare a relatively simple computerized technique; a more sophisticated, context-sensitive computerized approach; and a context-sensitive, human-scored system. Seventy-one subjects, representing four diagnostic groups, provided free-speech samples which were scored according to all three methods. Data from each method were then submitted to discriminant and classification analyses. In comparing the classification performance of the three methods, we found that both computerized methods were more accurate than the human-scored method. The time and cost benefits of computerized systems are discussed.  相似文献

Subjective contours were compared with objective contours in their ability to facilitate performance in speeded tasks that required judging the position of a dot or the slope of a line segment relative to the contour. Subjective contours were found to reduce both reaction times and error rates for dot localization but not for the more difficult slope discrimination task. These results add to the growing body of evidence suggesting that subjective contours have functional properties similar to those of objective contours.  相似文献

Subjects in an exercise training condition participated in a 10-week aerobic exercise class, whereas subjects in waiting-list control and independent control conditions did not. The results indicated that subjects in the training condition evidenced reliably greater improvements in physical fitness (aerobic capacity) and reported reliably greater improvements in their abilities and confidence in both the physical area (e.g., ability to run distances) and nonphysical area (e.g., frustration tolerance) than did subjects in the control conditions. On the other hand, improvements in physical fitness were not related to reported improvements in abilities and confidence. These findings are of interest because they indicate that some of the important personal changes that are associated with physical fitness training are not due to changes in fitness, but appear to be due to other factors (e.g., group participation and expectancies).  相似文献
