The concept of the self refers to how individuals represent, evaluate, and relate to themselves across different contexts. It encompasses a range of psychological processes, from relatively stable beliefs about personal characteristics to dynamic experiences of self-awareness and agency.
Rather than being a single construct, the self is typically understood as a system that includes multiple interrelated components. These include how people describe themselves (self-concept), how they evaluate their worth (self-esteem), how capable they perceive themselves to be (self-efficacy), and how they experience coherence, authenticity, and continuity in their identity.
One important distinction is between the content of the self and the evaluation of the self. Self-concept refers to the structure and organization of self-knowledge – the traits, roles, and attributes individuals associate with themselves. Self-esteem reflects the evaluative aspect of this system, capturing the degree to which individuals view themselves positively or negatively. Some approaches further distinguish between global self-esteem and more context-dependent or contingent forms of self-worth.
Another key dimension involves agency and control. Self-efficacy and related constructs reflect beliefs about one's ability to act effectively and influence outcomes. These beliefs play a central role in motivation, persistence, and behavior, linking the self-system to goal-directed action.
The self is also defined by how it is organized and maintained over time. Identity-related constructs focus on processes such as commitment, exploration, and coherence, as well as on broader ways of defining the self in relation to others (e.g., independent vs. interdependent self-construal). These processes contribute to a sense of continuity and personal meaning.
In addition, the self can be examined in terms of awareness and reflexivity. Some individuals are more likely to direct attention toward their internal states, engage in self-reflection, or monitor how they are perceived by others. These tendencies are captured by constructs such as self-consciousness, reflection, and rumination.
Finally, contemporary approaches emphasize the importance of how individuals relate to their own experiences. Constructs such as authenticity, self-concept clarity, and self-compassion reflect the degree of alignment, coherence, and acceptance within the self-system. These processes are closely linked to psychological well-being and adaptive functioning.
Together, these perspectives highlight the self as a complex and multifaceted system that integrates cognitive, emotional, and motivational processes. The instruments presented in this domain assess different aspects of this system, allowing for a more differentiated understanding of how individuals experience and regulate themselves.
