Wendy Treynor
Wendy Treynor is the first author of the 2003 analysis that split rumination into two different habits, brooding and reflective pondering. Her team stripped out of the standard rumination questionnaire every item that overlapped with the symptoms of depression, which had been the long-standing complaint about the measure, and looked at how people answered what was left in a community sample of 1,328 people. Two groups of five questions came out, and only one of them went with worse depression over time.
Who they are
Credit her, not the famous name on the paper. The analysis is routinely cited as a refinement by its third author. Treynor is the first author and the work is hers, and this site names her first every time.
Her given name was carried wrongly in this vault before it was checked, and the correction is recorded here rather than made quietly. The paper lists Wendy Treynor, Department of Psychology, University of Michigan. This publication's practice is to print its own corrections, because a correction that leaves no trace is indistinguishable from never having been wrong.
No later post has been verified, so none is claimed. The affiliation above is the one on the 2003 paper.
Key papers
Treynor, W., Gonzalez, R., & Nolen-Hoeksema, S. (2003). "Rumination reconsidered: a psychometric analysis", Cognitive Therapy and Research, 27(3), 247 to 259. First author. A randomly selected community sample of 1,328 people. Ten surviving items, two groups of five. Brooding went with more severe depression at the time and over the following year; reflection went with less depression at longer follow-up. Full text public on the University of Michigan pages of her co-author.
Key ideas
The two habits, in plain words. Brooding asks why do I always react this way, and measures you against a standard you did not meet. Reflective pondering asks what happened and what you would do differently. They feel almost identical from inside a bad evening, and only one of them predicts getting worse.
The method is what makes the finding trustworthy. Removing the items that were really asking about depression symptoms was the necessary step. Without it, the old result was at risk of being the discovery that depressed people are depressed.
The honest limit, carried in plain sight. The split is half-solid. It is much better established for brooding than for reflection. And Whitmer and Gotlib, in 2011, could not recover the two-part structure at all in people who were currently depressed, and concluded that the distinction may be undetectable inside a live depressive episode. That is an uncomfortable result for a construct whose whole purpose is predicting depression.
Where this site lands. Side one, with the limit visible. The defensible claim is that the two are different in kind and that it is the brooding kind that does the damage. The claim this site does not make is that somebody inside a depressive episode can simply swap one for the other. That is a prescription the evidence has not earned, and Whitmer and Gotlib are the reason.
