Cummings (1995) stated that any changes in a family environment due to parental depression increase the risk of developing a mood disorder in children. The result of this can be found as early as preschoolers and infants, due to the insecure attachment they develop with their parents. The emotional distress of children can also have an effect on their parents, causing depression that in turn will also affect the children, theoretically creating a never-ending cycle unless they seek treatment. Sometimes It is not the depressed parents that lead to the onset of depression in their children, but rather it is the change in the family environment that stems from the parents' depression that causes the children to become depressed. Some studies suggest that martial troubles are a better predicator for the onset of depression than the depression of the parents or the children themselves (Cummings, 1995).
