The purpose of this study was to examine individuals’ sense of competence contained in their sense of coherence (SOC). There are two aspects of competence: self-esteem (SE) and assumed-competence (AC). Self-esteem relates to essential aspects rooted in personal experiences, while assumed-competence pertains to illusory aspects not rooted in personal experiences but based on undervaluing others. Data of 183 college students were analyzed. Results indicated a positive correlation between SOC and SE, and a negative correlation between SOC and AC. Thus, sense of competence contained in SOC may not be based on illusory aspects and on undervaluing others.
