Beneficial effects of self-affirmation on motivation and performance reduced in students hungry for others' approval

Researchers have suggested that the self-affirmation intervention may motivate students to approach a challenging task and improve their performance. However, we posited that self-affirmation may not be beneficial for students whose self-esteem is based more on others' approval (i.e., having high others' approval contingencies of self-worth; OACSW). This is because the main motive for undertaking a challenging task among high OACSW students may be to obtain others' approval and increase self-esteem. Being self-affirmed may increase high OACSW students' sense of self-integrity, satisfying this motive, and thus cause them to perceive a lower value in undertaking the task. Consequently, high OACSW students would be less inclined to undertake the task and would not perform more favorably on it after being self-affirmed. In support of this hypothesis, the results of Experiment 1 (value affirmation) and Experiment 2 (attribute affirmation) showed that for high school students who did not receive self-affirmation, OACSW tended to be positively associated with their tendencies to confront a challenging task and their performance. However, for self-affirmed participants, the positive relationships between OACSW and both their tendencies to confront the task and performance flattened, and even went negative, mainly through a reduction of perceived value in confronting the task. Potential underlying mechanisms and implications are discussed.
