The Elder Life Adjustment Interview Schedule (ELAIS) was developed as an age- and culture-sensitive assessment device for depression and 9 environmental, behavioral, and health correlates (Schlatter et al., 1993, J. MARC Res. 1: 27–42). The psychometric adequacy of the ELAIS has been demonstrated with samples of elder Americans of Asian, Caucasian, and Native Hawaiian ancestry (Dubanoski et al., 1996, J. Clin. Gerospsychol. 2: 247–262). This study reports on the reliability and construct validity of a translated Japanese version. Participants were 55 community-dwelling elders living in the areas surrounding Maebashi, Japan. The ELAIS contains 14 scales of which 9 represent theoretical predictors of depression. The 2 Environmental Condition scales measure life events and social support. The 4 Behavioral Competency scales measure recreational activity, assertiveness, self-reinforcement, and perceived control. The 3 Health Factor scales measure perceived health, functional ability, and objective health. The 5 Other scales measure demographics, depression, life satisfaction, cognitive functioning, and response style. Results yielded acceptable internal consistency and stability reliability coefficients for all but 1 of the subscales on the ELAIS (informational social support). Construct validity support was found for the Depression scale and 6 theoretical predictors, including life events, recreational activity, assertiveness, self-reinforcement, functional ability, and objective health. Treatment and prevention implications for the cross-ethnic multivariate assessment of depression among elders are discussed.  相似文献

We tested the fit of the social cognitive choice model [Lent, R.W., Brown, S.D., & Hackett, G. (1994). Toward a unifying social cognitive theory of career and academic interest, choice, and performance [Monograph]. Journal of Vocational Behavior, 45, 79-122] to the data across gender, educational level, and type of university among students in a variety of computing disciplines. Participants were 1208 students at 21 historically Black and 21 predominantly White universities. They completed measures of self-efficacy, outcome expectations, interests, goals, and social supports and barriers with respect to computing majors. The SCCT model yielded adequate fit to the data across each of the grouping variables. Implications for future research on SCCT’s choice hypotheses in the context of science and engineering-related fields are discussed.  相似文献

The aim of this paper is to present a mathematical dynamic modelling of the effect a stimulant drug has on different people which, at the same time, can be a useful tool for future brain studies. To this end, a dynamic model of the evolution of extraversion (considering its tonic and phasic aspects) has been constructed taking into account the unique personality trait theory and the general modelling methodology. This model consists of a delayed differential equation which, on one hand, considers that the active stimulus, a consequence of a single intake, is not constant; on the other hand, it contemplates that the state variable representing the phasic extraversion also represents the brain activation. The derivative of this state variable is calculated as the sum of the homeostatic control flow, the excitatory effect flow and the inhibitor effect flow. The solutions of this equation relate the tonic activation of an individual (that characterizes his or her personality) with his or her phasic activation level, whose evolution over time describes the organism's response to a single drug intake. These solutions quantitatively reproduce the predictions of current personality theories and anticipate vulnerability to drug misuse and addiction development.  相似文献

Social relations in the workplace are one of the main sources of risk for the onset of mobbing. In this work, we analyzed, through the perceived social climate, the influence of interpersonal relations on the characterization of the processes of mobbing, in a sample of local police (N = 235). In particular, the policemen and women's opinions of the quality of the personal relations among the group members and the treatment they receive from the command posts were assessed. The results of the study show that the development of guidelines of social interaction based on discrimination and abuse of authority are predicting variables of mobbing in this group.  相似文献

This work shows the association between personality variables, such as cognitive and affective variables, and psychological adjustment, such as life satisfaction and depressive symptoms. Accordingly, this study assessed the role of outcome expectancies (optimism and pessimism) and affectivity (positive and negative affect) as a predictors of life satisfaction and depressive symptoms. A total of 458 students from the University Rovira i Virgili completed the scales LOT-R, PANAS, the Satisfaction with Life Scale and BDI. Path analysis results suggest that affectivity variables are more important to predict life satisfaction and depressive symptoms than outcome expectancies. Implications for future research are discussed.  相似文献

This study investigates the power of tangible dimensions of service quality to predict customer satisfaction. For this purpose, we statistically controlled the effects of dimensions of service quality that describe social interaction between employees and customers, both functionally and relationally. A field survey was conducted with the participation of 556 customers of a sports centre. The results showed that tangible dimensions of service quality predicted an additional and significant amount of customer satisfaction variance, beyond the effects of service quality of the social interaction. The article concludes with the discussion of the implications of these results.  相似文献

In the research area, the criterion to test a hypothesis is frequently the distance of each subject from the mean of the distribution. This concept of distance is constantly used and re-used as a source of evidence in the search for significant contrasts with respect to models of theoretical probability. This paper proposes a number of ideas regarding the use of new distance indicators related to statistics that rely less heavily on parametric assumptions, in particular, the use of median confidence intervals. We have simulated via EXCEL different data samples for a design of two independent groups under 15 different conditions in two different situations: mean equality and mean differences. The results showed the high sensitivity of the comparison of the confidence intervals, especially if a strict decision criterion is used. However, we did not obtain good results for sensitivity. In fact, in some cases, the comparison of the confidence intervals of the mean worked better than those of median.  相似文献
