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

Extensive research has identified individual differences associated with sex in a range of visual task performances, including susceptibility to visual illusions. The aim of this study was to identify the locus of sex differences within the context of the Poggendorf illusion. 79 women and 79 men participated within a mixed factorial design. Analyses indicated that sex differences were only present in the stimulus context with the full inducing element present. This finding replicates recent research and provides qualifying evidence as to the locus of the effect. The findings are discussed within the functional framework of perceptual processes involved in extrapolating 3-dimensional characteristics from 2-dimensional visual stimuli. 相似文献

There is growing evidence that Internet-mediated psychological tests can have satisfactory psychometric properties and can
measure the same constructs as traditional versions. However, equivalence cannot be taken for granted. The prospective memory
questionnaire (PMQ; Hannon, Adams, Harrington, Fries-Dias, & Gibson, 1995) was used in an on-line study exploring links between
drug use and memory (Rodgers et al., 2003). The PMQ has four factor-analytically derived subscales. In a large (N763) sample
tested via the Internet, only two factors could be recovered; the other two subscales were essentially meaningless. This demonstration
of nonequivalence underlines the importance of on-line test validation. Without examination of its psychometric properties,
one cannot be sure that a test administered via the Internet actually measures the intended construct. 相似文献

注意对半视野识别汉字的影响 总被引:2,自引:0,他引:2
用视觉外周呈现光点以控制注意的方法,对识别具体和抽象性汉字的脑功能偏侧化进行了研究。注意线索与刺激字在同侧视野呈现的间隔时间(SOA)分为0、29和57ms。结果表明,具体性字在三种SOA都表现出右视野左半球优势;而抽象性字在0ms两视野的识别成绩一样好。因此在偏侧视野识别汉字词中注意和脑结构因素似乎起着综合作用。 相似文献
