Body pain and treatment response in late-life depression.   总被引:2,自引:0,他引:2  
OBJECTIVE: The authors investigated the influence of body pain on 1) time to treatment response and 2) suicidal ideation, in late-life depression. They hypothesized that higher levels of body pain would predict a longer time to and lower likelihood of response, and increased levels of suicidal ideation. METHODS: Subjects (N=187) were older adult outpatients (age > or =69 years), with current episodes of major depression, who were openly treated with paroxetine up to 40 mg daily and weekly interpersonal psychotherapy. Response was defined as 3 consecutive weeks of Hamilton Rating Scale for Depression at < or =10. Body pain was measured with the Bodily Pain Index of the SF-36 quality-of-life assessment. Authors used survival-analysis models on the responder sample to test the effect of body pain on response, after controlling for severity of depression. RESULTS: Overall response rate was 75.4%. Nonresponders reported more severe pain at baseline. After covarying for severity of baseline depression, no effect was found for physical pain on time-to-response or degree of suicidality. Bodily pain remained stable during acute treatment for responders, independent of depression response to combination psychotherapy and antidepressant treatment. CONCLUSIONS: Older adult patients with higher levels of physical pain can still respond to antidepressant treatment; however, reported bodily pain may be associated with a more difficult-to-treat depression.  相似文献

Occupations have been a relatively neglected risk factor in the etiology of suicide. Client-oriented occupations are often thought to contribute to suicide by increasing psychological stress. The present study tests this thesis for the case of social work. Data were collected from 21 reporting states in the year of 1990. Controls are introduced for possible covariates of social work including gender, race, region, age, and marital status. The results of a preliminary logistic regression analysis found that being a social worker increased the odds of death by suicide by 55.6%, compared to the rest of the working age population. However, when controls for other occupations were incorporated into the analysis, social workers were no longer at elevated odds of death by suicide relative to other professional-managerial occupations. The psychological resources and training of social workers may act as buffers against occupational stress. Being Caucasian, male, younger, and being non-married all increased the odds of death by suicide.  相似文献
