Abstract

Objective To examine explanatory style (how people explain life events) as a risk factor for early death, using scores from the Optimism-Pessimism scale of the Minnesota Multiphasic Personality Inventory (MMPI). Subjects and methods A total of 839 patients completed the MMPI between 1962 and 1965 as self-referred general medical patients. Thirty years later, the vital status of each of these patients was ascertained. Results Of the 839 patients, 124 were classified as optimistic, 518 as mixed, and 197 as pessimistic. Follow-up was available for 723 patients. Among these, a 10-point T-score increase on the Optimism-Pessimism scale (e.g., more pessimistic) was associated with a 19% increase in the risk of mortality. Conclusion A pessimistic explanatory style, as measured by the Optimism-Pessimism scale of the MMPI, is significantly associated with mortality.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
