As predicted, people who scored higher on a measure of Self-defeating Personality reported experiencing less pleasure and enjoyment from individual and social activities as well as from personal accomplishments. The results were consistent with the idea that these people maintain a self-image of "loser" by minimizing or discounting positives in their lives. Results were also consistent with prior research showing a positive relationship between self-defeating personality and depressive affect.
