Predictors of time to remission from depression in primary care patients: do some people benefit more from positive life change than others?

The authors examined the role of personality, social support, and coping strategies and their interaction with positive life change (PLC) in influencing time to remission from depression in 86 depressed primary care patients (69% women, mean age = 36.6 years), who were followed for 3.5 years. Diagnostic information was obtained by the Present State Examination (J. K. Wing, J. Cooper, & N. Sartorius, 1974), and life change by the Life Events and Difficulties Schedule (G. W. Brown & T. O. Harris, 1978). The association of PLC and other predictors with the time to remission was studied by means of Cox regression. PLC reduced time to remission in women, but not in men. Other predictors that expedited remission were low severity of premorbid difficulties, high self-esteem, and a tension-reducing coping style. Neuroticism modified the effect of PLC in that the remission forward bringing effect of PLC was stronger for highly neurotic people. The results suggests that women and psychologically vulnerable persons benefit most from PLC.
