Two hundred and fifty-two undergraduates completed a modified version of the Life Experience Survey (LES), the Beck Depression Inventory (Revised), and a measure of social support. Correlations between negative and total life changes on the LES and the Beck were significant for individuals with high social support (r=.36 and .29), but these correlations were significantly higher for individuals with low social support (r=.67 and .66). In addition, positive LES scores were significantly correlated with the Beck for individuals with low social support (r=.37), and individuals with low social support had higher mean scores on the Beck,F(1,250)=20.72,p<.0001. These findings were interpreted as supporting the theory of Holmes and Rahe and Sarason and Johnson that aversive life changes are related to depression, and provide evidence for the view the positive life changes can also be stressful. These data also support the concept of individual differences in vulnerability to stress and the role of social support in this vulnerability. The use of social support as a moderator variable appears to enhance correlations between the LES and depression to the level of clinical utility. 相似文献

Tables are given for the calculation of variances of maximum-likelihood estimates in a multiple biserial model. For the estimates of individual correlations between the dichotomized variable and each of the graduated variables additional calculation is necessary; variances for estimates of the multiple correlation and the point of dichotomy are available directly. The required formulas and notation are those of a recent paper by Hannan and Tate.Research sponsored by the National Science Foundation under grant NSF-GP219.Aero-Space Division (Applied Mathematics), Seattle, Washington. 相似文献

This project employs an experimental design to test theoretical predictions regarding how numeracy can assist jurors in determining damage awards to compensate a plaintiff for pain and suffering and how the use of meaningful numerical anchors may produce similar benefits. Mock jurors (N = 345) reviewed a legal case and were asked to give a dollar award to compensate the plaintiff for pain and suffering. The presence and nature of a numerical anchor and the duration of pain and suffering were manipulated. Participants' numeracy was measured. Results provided support for predictions. Jurors higher in numeracy gave awards that more appropriately reflected the duration of pain and suffering and showed less variability in awards. Similar benefits were obtained by exposing jurors to meaningful numerical anchors to help them contextualize dollar amounts. Thus, introducing meaningful anchors to jurors may provide similar benefits to numeracy, without the drawbacks associated with selecting only numerate jurors. 相似文献
