Unearned Self-Praise Can Trigger Depression New research suggests self-talk to boost self-esteem may backfire and cause depression, if the message is untruthful.

However, investigators discovered high and low performers felt fine when they assessed themselves accurately — probably because the high performers recognized their strengths and low performers acknowledged their weaknesses and could try to improve their future performance.

“These findings challenge the popular notion that self-enhancement and providing positive performance feedback to low performers is beneficial to emotional health. Instead, our results underscore the emotional benefits of accurate self-assessments and performance feedback,” said lead author Young-Hoon Kim, Ph.D., of the University of Pennsylvania.

The study is found in the journal Emotion.

Investigators performed four experiments with different groups of young people from the United States and Hong Kong. Three U.S. groups totaled 295 college undergraduates, with 186 women and a mean age of 19. One Hong Kong group consisted of 2,780 high school students, with 939 girls from four different schools and spanning grades 7-12.

In the first two experiments, one of the U.S. groups and the Hong Kong students took academic tests and were asked to rate and compare their own performances with other students at their schools.

Following their assessments, all the participants completed another widely used questionnaire to assess symptoms of depression.

In the third and fourth experiments, researchers evaluated the other two sets of U.S. undergraduates with feedback exercises that made high performers think their performance was low and low performers think their performance was high. Control groups participated in both and received their scores with no feedback.

Researchers found in all studies that those who rated their own performance as much higher than it actually was were significantly more likely to feel dejected.

“Distress following excessive self-praise is likely to occur when a person’s inadequacy is exposed, and because inaccurate self-assessments can prevent self-improvement,” said co-author Chi-Yue Chiu, Ph.D., of Nanyang Technological University in Singapore.

The results also revealed cross-cultural differences that support past findings that Asians are more humble than Americans.

The U.S. undergraduates had a higher mean response when rating their performance than the Hong Kong students, at 63 percent compared to 49 percent, the researchers found.

Nevertheless, researchers discovered excessive self-enhancement was related to depression for both cultures.
