A seven-year study by researchers at the University of Alberta tracked 600 college graduates, aged between 20 and 29, measuring their levels of depression and anger and seeing how they were affected by changing life circumstances. The graduates showed a significant decrease in depression and anger over the course of the study. Younger participants were more depressed at times when they lived on their own while older participants were more depressed when they lived with their parents. While home was a haven for younger adults the longer people stayed at home, or if they returned home, the more likely they were to experience symptoms of depression. Women were more depressed and angry at the start of the study than men. Becoming a parent led to an increase in anger as people struggled to come to terms with the demands of parenthood.
