Final answer:
The study by Eaton et al. (2008) on tracking vulnerability to depression focused on identifying predictive factors for the disorder. While the specifics of this study weren't detailed, related research shows that vulnerability to depression is affected by genetic, environmental.
Step-by-step explanation:
The study by Eaton et al. (2008) aimed to track vulnerability to depression and identify factors that might predict a person's risk of developing this condition. While the specifics of Eaton et al. (2008) study were not provided, related research indicates that the epidemiology of depression involves understanding the prevalence, risk factors, and distribution of depression among populations.
Vulnerability to depression can be influenced by a variety of factors including genetic predisposition, stressful life events, and gender differences.
Studies like Kessler et al. (2003, 2005, 1997) have focused on the lifetime prevalence of depressive disorders and the impact of stressful life events on depression. Fitzgerald et al. (2008) conducted a meta-analysis on changes in brain activation, providing insight into the biological factors related to depression.
The works of Bromet et al. (2011), Hasin et al. (2011), Mazure (1998), Peterson & Seligman (1984), and Stansfeld et al. (2012) contribute to a broader understanding of how depression can occur across different demographics and under various social and occupational stressors.
Nolen-Hoeksema et al. (1999) have also explored the gender difference in depressive symptoms, which is a key aspect when considering vulnerability and the development of depression.
In conclusion, research into tracking vulnerability to depression is multifaceted, encompassing biological, psychological, and social factors that contribute to the onset and course of the disorder.
