Chinese Journal of Behavioral Medicine and Brain Science 2009;18(6):547-550
Objective To test the diathesis-stress component in the hopelessness theory and demonstrate the mediator effect of hopelessness in depression-generating process. Methods In the 6-month longitudinal study,latent growth curve model(LGM) was used in a sample of 269 Chinese undergraduates on the base of questionnaire investigation. Results The intercept for hopelessness depression had a significant association with the intercept for negative life events (path coefficient =0.48) and depressogenic attributional style (path coefficient=0.26).The slope for hopelessness depression had a significant association with the slope for negative life events (path coefficient=0.73). The complete mediator effect of hopelessness between depressogenic attributional style and the intercept for hopelessness depression was 0.143. The complete mediator effect of hopelessness between the slope for negative life events and the intercept for hopelessness depression was 0.131. The partial mediator effect of hopelessness between the intercept for negative life events and the intercept for hopelessness depression was 0.151.Conclusion Depressogenic attributional style interacted with the occurrence of negative events to predict the occurrence of hopelessness depression. Hopelessness made partial mediator effect on the hopelessness depression-generating process.
