Susan Nolen-Hoeksema

Dr. Susan Nolen-Hoeksema was born on May 22, 1959, in Springfield, Ill., to John and Catherine Nolen. Her father ran a construction business, where her mother was the office manager; Susan was the eldest of three children.

Susan Nolen-Hoeksema, psychologist and writer, helped explain why women are twice as prone to depression as men and why such low moods can be so hard to shake. Dr. Nolen-Hoeksema, a professor at Yale University, began studying depression in the 1980s.

She entered Illinois State University before transferring to Yale. She graduated summa cum laude in 1982 with a degree in psychology. After earning a Ph.D. in psychology at the University of Pennsylvania, she joined the faculty at Stanford. She later moved to the University of Michigan, before returning to Yale in 2004.

Along the way she published scores of studies and a popular textbook. In 2003 she became the editor of the Annual Review of Clinical Psychology, an influential journal.

Her studies, first in children and later in adults, exposed one of the most deceptively upsetting of these patterns: rumination, the natural instinct to dwell on the sources of problems rather than their possible solutions. Women were more prone to ruminate than men, the studies found, and in a landmark 1987 paper she argued that this difference accounted for the two-to-one ratio of depressed women to depressed men.

She later linked rumination to a variety of mood and behavior problems, including anxiety, eating disorders and substance abuse.

Dr. Nolen-Hoeksema wrote several books about her research for general readers, including “Women Who Think Too Much: How to Break Free of Overthinking and Reclaim Your Life.” These books described why rumination could be so corrosive — it is deeply distracting; it tends to highlight negative memories — and how such thoughts could be alleviated.
