Among traumatized Cambodian (N=90) and Vietnamese (N=94) refugees attending a psychiatric clinic, the study examined the validity and psychometric properties of the Short Form-36
Health Survey (SF-36), a measure of self-perceived mental and physical health. In both patient samples, all eight SF-36 scales
displayed excellent internal consistency (item-scale correlations and Cronbach's α). But, similar to other studies of Asian
samples, (a) the Vitality (VT) scale did not separate from the Mental Health (MH) and General Health (GH) scales, as evidenced
by item-scale and interscale correlations, and (b) the VT scale loaded as strongly (Vietnamese sample) or more strongly (Cambodian
sample) than the MH scale on the so-called Mental Factor in a two-factor solution of the eight scales (with the GH scale also
loading heavily on the same factor). 相似文献

In this study, we compared panel designs applied with various routing methods in the multistage test (MST) based on the partial credit model in the context of classification testing. Simulations were performed to compare three routing methods and four panel structures. Conditions of two test lengths and three passing rates were also included. The results showed that, regardless of the routing method used, the same panel structure performed similarly in terms of the precision of the classification decision with the same test length condition. The longer test length produced higher accuracy, whereas the 50 % passing rate yielded the lowest accuracy. Finally, all MST conditions performed well in terms of test security. 相似文献

The effect of brand personality and brand identification on brand loyalty: Applying the theory of social identification 总被引:4,自引:0,他引:4
This study investigated the effect of brand personality on brand asset management by using the concept of consumers' identification with a brand. The focus was on one important type of high-technology product, the cellular phone. The authors develop a conceptual framework to explain the effect of brand identification on brand loyalty. The important variables of this framework include the attractiveness of the brand personality, the distinctiveness of the brand personality, the self-expressive value of the brand personality, positive word-of-mouth reports of the brand, and brand loyalty. The empirical results indicated that there are positive relationships between attractiveness, distinctiveness, and self-expressive value of brand personality. These relationships had a statistically significant effect on consumers' identification with a brand. Furthermore, brand identification had a direct effect on word-of-mouth reports and an indirect effect on brand loyalty. The theoretical and managerial implications of the empirical results are presented, and suggestions are made regarding both the limitations of the present study and future directions for research. 相似文献

Copying skills in relation to word reading and writing in Chinese children with and without dyslexia
Because Chinese character learning typically relies heavily on rote character copying, we tested independent copying skill in third- and fourth-grade Chinese children with and without dyslexia. In total, 21 Chinese third and fourth graders with dyslexia and 33 without dyslexia (matched on age, nonverbal IQ, and mother’s education level) were given tasks of copying unfamiliar print in Vietnamese, Korean, and Hebrew as well as tests of word reading and writing, morphological awareness, rapid automatized naming (RAN), and orthographic processing. All three copying tasks distinguished dyslexic children from nondyslexic children with moderate effect sizes (.67-.80). Zero-order correlations of the three copying tasks with dictation and reading ranged from .37 to .58. With age, Raven’s, group status, RAN, morphological awareness, and orthographic measures statistically controlled, the copying tasks uniquely explained 6% and 3% variance in word reading and dictation, respectively. Results suggest that copying skill itself may be useful in understanding the development and impairment of literacy skills in Chinese. 相似文献

Is the Third‐Person Effect Real? A Critical Examination of Rationales,Testing Methods,and Previous Findings of the Third‐Person Effect on Censorship Attitudes 下载免费PDF全文
Regarding the effect of the third‐person perception on censorship attitudes, the present study first highlighted logical weaknesses of previously proposed rationales and limitations of previously used statistical models to test the effect. This study reanalyzed data from past research on the effect of the third‐person perception. In Study 1, the average effects of the other‐self perceptual gap in the media influence on censorship attitudes were estimated based on reports from 13 previous studies (total N = 6,414). Study 2 reanalyzed Schmierbach, Boyle, Xu, and McLeod's (2011) correlational data (N = 692). The results of these two studies showed that the presumed effect on others is a stronger predictor of censorship attitudes than the other‐self differential in perceived media effect. 相似文献

This cross‐sectional study investigated the usefulness of the emotional Stroop task (EST) as a behavioral marker for suicidal behaviors in a college population. Eight hundred twenty college students were asked to perform on the EST and to respond to suicide‐related self‐report measures. The results indicated that past suicide attempters were slower in responding to the word “suicide” as compared to nonattempters, and female past attempters showed more delayed response when their most recent attempt was made in the past 12 months. We did not find evidence that the EST could outperform the traditional self‐report measures. 相似文献

Auditory event-related potentials (ERPs) were investigated in an oddball paradigm to verify electrophysiological evidence of music expectation, which is a key component of artistic presentation. The non-target condition consisted of four-chord harmonic chord sequences, while the target condition was manifested by a partially violating third chord and a resolving fourth chord. The results showed that the specific mismatch negativity (MMN) elicited in the resolving chord is as robust as that elicited in the partially violating chord. Moreover, the P3b (P300) elicited in the resolving chord was smaller than the one in the violating chord. Taken together these data indicates that the human brain pre-attentatively may be able to anticipate a subsequent resolving chord when music expectation is generated by a partially violating chord. 相似文献

This study aimed to investigate the hypothesis that administration of the air with 30% oxygen compared with normal air (21% oxygen) enhances cognitive functioning through increased activation in the brain. A visuospatial task was presented while brain images were scanned by a 3 T fMRI system. The results showed that there was an improvement in performance and also increased activation in several brain areas in the higher oxygen condition. These results suggest that a higher concentration of breathed oxygen increases saturation of blood oxygen in the brain and facilitates performance. 相似文献

The study was done to check replication of changes in sensitivity with a simple simulator as had been obtained in an experiment using the real road situation. Another purpose was to control simulator sickness which could have confounded data from testing with a simulator or in actual driving. Sensitivity of the drivers (72 healthy young adults, M age = 24 yr., SD = 5) while performing the driving task was measured in terms of subjective ratings of simulator sickness and affect, and physiological measures (i.e., galvanic skin responses and skin temperature) at different driving speeds and in driving mode conditions, using a simple vehicle simulator. Analysis showed measures of drivers' state, including simulator sickness, physiological indices, and subjective reports, increased with driving speed (30 --> 90 -->120 km/hr.) and driving mode change from the regular speed to sudden increasing to sudden decreasing speeds. Particularly, the results suggest that the increased autonomic nervous activation induces increase of rated simulator sickness. Based upon the same tendency in change of the simulator sickness and physiological state with driving speed and driving mode conditions, it was concluded that, if the results obtained from the simulator experiment can be generalized to the real situation, the simulator sickness must be considered a confounding factor. The results also suggest that the changes in human sensitivity are dependent upon aspects related to speed of a vehicle and driving mode. 相似文献
