The role of personal, relational, and collective self-esteem in predicting acute salivary cortisol response and perceived stress.

Personal self-esteem (PSE) has been well recognized as a buffer against stress; however, the effects of other types of self-esteem, such as relational self-esteem (RSE) and collective self-esteem (CSE), on stress have not been adequately explored. This study investigated the roles of PSE, RSE, and CSE in reducing stress response. The Rosenberg, Relational, and Collective Self-Esteem Scales were adopted to assess PSE, RSE, and CSE, respectively. Participants underwent an acute social stress paradigm, and their acute stress response was assessed using subjective stress reports and salivary cortisol levels. Chronic stress level was estimated using the Perceived Stress Scale and hair cortisol concentration. The results showed that PSE was negatively correlated with salivary cortisol response during acute social stress; however, no significant associations were found between any type of self-esteem and subjective stress reports. For chronic stress, all types of self-esteem were negatively associated with perceived stress level, but not with hair cortisol concentration. Further hierarchical regression analyses suggested that only PSE negatively predicted acute salivary cortisol response and perceived stress level. Overall, the findings suggest the essential role of PSE in predicting acute salivary cortisol responses and perceived stress.
