The concept of self-respect has received little attention in the psychological literature and is not clearly distinguished from self-esteem. The present research sought to empirically investigate the bases of self-respect by manipulating adherence to morals together with interpersonal appraisals (IAs), or task-related competence, in hypothetical scenarios (Studies 1a and 1b) and a situation participants relived (Studies 2 and 3). Participants' levels of state self-respect and self-esteem were measured. Studies 1 to 3 found main effects of adherence to morals on self-respect, with self-respect mediating the effect of adherence to morals on self-esteem, but little support for competence and IAs directly influencing self-respect. Self-respect uniquely contributed to anticipated/felt self-esteem alongside competence or IAs. The pattern of results supports the conceptualization of self-respect as a component of self-esteem associated with morally principled conduct, distinct from performance and social self-esteem. The findings have implications for our understanding of self-esteem and moral behavior.
