身近な他者への相談後の意思決定における後悔と自己統制感の関連

－意思決定の結果及びプロセスに対する後悔に着目して－

抄録

This study focused on regret about decision making under consultation with a friend. We investigated the relationship between two kinds of regret (regret for the consultation and regret for the result), the decision maker’s Locus of Control, and the opinions offered by the friend (the opinion influencing the final decision or not). One-hundred-ninety university students read two scenarios, then filled out a questionnaire. The results showed people with high external control felt more regret for their decisions than people with internal control. Furthermore, people felt more regret for consultation when the opinion the friend gave was instrumental in the final decision of the decision maker than not. These results suggest the factors that influence each regret are different and, that it is effective to seek opinions from others, considering various options toward partially reducing regret in decision making.
