The assessment of anxiety disorders in late life is often hindered by the lack of measures specifically validated with older adults. Because anxiety manifestations may vary across age groups, it is important to design new instruments or validate existing measures with older adults. This study examined the psychometric properties of the Beck Anxiety Inventory (BAI) in a sample of 281 older adults who were community-dwelling (82.6%) or living in residential care facilities (17.4%). The mean total BAI score was 6.5 (SD = 7.2), indicating minimal anxiety symptomatology in this older sample. There was a trend for older subjects to score higher. Females scored higher than males, and subjects living in a residential facility scored higher than did community dwellers. Item-total correlations were in the moderate range and the internal consistency of the BAI was adequate (alpha = 0.89). A factor analysis yielded a six-factor structure accounting for 64.6% of the variance, with a somatic factor accounting for the largest portion of the variance (32.2%). Because somatic symptoms are more prevalent with aging, such symptoms should not be weighed as heavily in the total BAI score as cognitive or behavioral symptoms. The findings indicate that the BAI is a useful self-report scale for assessing anxiety symptomatology among older adults. 相似文献

Group psychotherapists, primarily members of the American Group Psychotherapy Association, were surveyed to determine their practice and attitude toward inclusion of patients receiving psychotropic medication in their "typical" outpatient psychotherapy groups. One hundred forty-three questionnaire responses were received from 258 contacted practitioners (55.4% return rate). More than two-thirds of the physicians, social workers, and psychologists reported including medicated members, and the professions did not significantly differ. Mood disordered patients were most frequently and schizophrenic and manic patients were least frequently reported to receive medication. Overall, clinicians' attitudes favored including medicated patients in the group. Indeed, therapists did not view inclusion of drugs as a detriment to the treatment process. Clinicians having only one medicated patient in their group felt more strongly that such individuals did not interfere with the treatment process when compared with those having none or more than one medicated patient. The one difference by discipline was that social workers and psychologists did not endorse the idea that medicated patients needed to be in groups led by psychiatrists. 相似文献

Duration estimates were assessed by the method of reproduction with filled reproduction intervals. Mental arithmetic, reading and mirror-image drawing were used in pairs as initial and/or reproduction tasks. All nine possible pairs of tasks were used in a 9 X 5 X 5 mixed design with five Ss per task pair and five interruption intervals for each initial task. Results indicated that, when arithmetic was used as the initial task, Ss underestimated the duration of the initial interval. When arithmetic was used as the reproduction task, Ss overestimated the duration of the initial interval. A significant correlation was obtained between arithmetic outputs and the lengths of the duration estimates. Results are interpreted as supportive of Burnside's (1971) interpretation of Ornstein's (1969) storage-size hypothesis. 相似文献

Langley Porter Neuropychtatrte Institute, University of California, San Francisco. Californta 94122 Response latencies to color are usually shorter than those to form. but sometimes this difference is absent or reversed. Three experiments investigated whether these differences result from differential susceptibility of color and form to extra focal processing. Experiment I showed shorter same-difference latencies to color than to form when two stimuli were presented simultaneously. This difference disappeared or reversed when the two stimuh appeared sequentially. Experiment II. using a multistimulus matching task, found that differences between response latencies to form and color were minimal at the center of the display and increased peripherally. Experiment III showed that eye movements were more frequent in matching forms than colors. Tasks that produced many eye movements had long average latencies, but the relationship between eye movements and latency was not a simple one. There was evidence both for parallel and serial strategies tn the use of the eyes to gather information. The results of these experiments are considered in relation to a theory of distributed attention. 相似文献

In response to Anderson's (1975) objections to Stone and Schneider's validation study of the Wheeler signs of homosexuality in the Rorschach, both the scientific and ethical-moral grounds for assessing sexual orientation were discussed. With respect to these two issues, it was argued that (a) an individual's sexual behaviors and attitudes, which includes sexual object preference, exert a significant influence on major portions of an individual's life and thus requires clinical assessment, and (b) only by gathering knowledge about human functioning in all domains can we effectively combat inappropriate stereotyping and prejudice, such as that which still exists towards homosexuals today. 相似文献

Luminance thresholds for downward moving contours were measured under several conditions of adaptation. Included was one condition which desensitized visual mechanisms responsive to downward motion. Another condition exerted equal effects on both up- and down-sensitive mechanisms. Thresholds for moving contours were unaffected by exposure to contours which moved in the opposite direction. This indicates that the perception of motion does not depend upon the relative activity in oppositely tuned, directionally selective visual mechanisms. 相似文献

Simulated supervisory responses to different patterns of absence were examined in a 2×2×2 factorial experiment. Annual employee absence records were varied in terms of frequency of absence, when in the year absences occurred (timing) and the mean time between absences. The responses of 73 raters to these records were evaluated in terms of perceived intentions of the employee, perceived impact on the company and raters' intentions to act. The results cast doubts on the role of attributions of intentionality as a mediator between absences and supervisory action. A three-way interaction on supervisor action suggests a three stage model in which frequency has the dominant effect, followed by timing and mean time between absences. 相似文献

In this study, we examined the secretory immune system, the body's first line of defense against invading organisms, and its relation to daily fluctuations of mood. Specifically, secretory immunoglobulin A (sIgA) was studied. Unlike other psychoimmunity studies that examined all sIgA protein regardless of specificity to invading organisms, ours examined an antigen-specific sIgA response to the oral administration of a harmless protein (rabbit albumin) and monitored the antibody produced in response to the protein. Dental students recorded their daily mood thrice weekly for 8 1/3 weeks, and parotid saliva was obtained from subjects during these contacts. Using a within-subjects analyses strategy, we found that antibody response was lower on days with high negative mood relative to days with lower negative mood, and conversely, sIgA antibody response was higher on days with high positive mood relative to days with lower positive mood. Results from total sIgA protein were in the opposite direction, although not significantly so. These results extend our knowledge of immunological changes and mood, and they suggest that minor life events' role in health may be mediated by the secretory immune system. 相似文献

Reeves and Sperling (1986) have developed an experimental paradigm and a model to explain how attention switching influences the storage of temporal-order information in short-term memory (STM), or working memory. The present article suggests that attention switching influences initial storage of items in STM, but that competitive interactions among the STM representations of stored items control the further evolution of temporal-order information as new items are processed. The laws governing these competitive interactions, called the long-term memory (LTM) invariance principle and the STM normalization rule, were originally derived from postulates that ensure that STM is updated in a way that enables temporally stable list learning in LTM to occur. Despite these adaptive constraints, and often because of them, temporal-order information is not always stored veridically. Both feedforward and feedback STM processes, with different invariant properties, are identified in the storage of temporal-order information. 相似文献
