Final answer:
The reference provided does not match Eaton et al. (2008) for a study on tracking vulnerability to depression. There are various studies that explore different aspects of depression, including brain activation patterns, the influence of stressful life events, childhood maltreatment, and epidemiological factors that contribute to an individual's vulnerability to depression.
Step-by-step explanation:
The study by Eaton et al. (2008) sought to track vulnerability to depression but there is no specific study by Eaton with that title from 2008 available for review. However, there are other significant studies cited which explore various aspects of depression. Among them, Fitzgerald et al. (2008) conducted a meta-analytic study that examined changes in brain activation in depression and found significant differences in brain patterns between depressed and non-depressed individuals.
Kessler's research, including his 1997 and 2003 studies on stressful life events and the epidemiology of women and depression respectively, highlight the importance of life events and gender as factors influencing the likelihood of developing depression. Peterson & Seligman (1984) discussed how causal explanations and cognitive style can be a risk factor for depression, indicating a psychological dimension to vulnerability. Furthermore, Nanni et al. (2012) focused on how childhood maltreatment predicts the course of illness in depression, emphasizing the impact of early life stressors.
Bromet et al. (2011) took a global perspective on the epidemiology of major depressive episodes, thereby contributing to the understanding of depression as a worldwide health concern. Kessler et al. (2005) addressed the lifetime prevalence and age-of-onset distributions of disorders, which can shed light on the patterns of vulnerability over a lifespan. Ultimately, studies like these inform the understanding of depression's multifactorial etiology, encompassing biochemical, psychological, and sociocultural factors.
