Self-esteem and self-enhancement are two critical phenomena that play major roles in social psychological theory and research. Everyone has an idea what self-esteem is; however, from an empirical standpoint, what exactly is self-esteem is hotly debated. The unidimensional definition of self-esteem defines it as a global assessment of one’s worth, with greater self-esteem being associated with greater self-worth. Whereas the multidimensional view of self-esteem defines self-esteem as a ratio of competences and worthiness. Furthermore, self-esteem can be broken down into different types: trait self-esteem is a stable view of the self that does not fluctuate much from day to day; state self-esteem is a more transitory view of the self that fluctuates from day to day; and domain-specific self-esteem relies on decisions we make about ourselves or self-evaluations about how we perform in specific situations. Regardless of type, there is an overall belief that humans have an innate need for high self-esteem and that they are particularly attuned to situations that may threaten this. When self-esteem is threatened, people enact behaviors aimed at increasing it: this is called self-enhancement. The idea that people are driven to self-enhance has become a popular topic in psychology and is found in some of the field’s most influential theories. For example, self-determination theory (SDT) examines both interpersonal and intrapersonal aspects of self-esteem and self-enhancement. Terror management theory (TMT) explains why human beings need self-esteem and how they self-enhance. Sociometer theory is concerned with understanding how self-esteem developed in humanity’s past and how it affects self-enhancement in the present. Finally, self-affirmation theory focuses on how people try to self-enhance after their self-integrity has been threatened.

Motivation is the largest single topic in psychology, with at least 32 theories that attempt to explain why people are or are not motivated to achieve. Within sport psychology research, there are a plethora of techniques of how to increase and sustain motivation (strategies to enhance agency beliefs, self-regulation, goal setting, and others). However, when explaining the conceptual undergirding of motivation in sport, the why of motivation, two theories predominate: Achievement Goal Theory (AGT) and Self-Determination Theory (SDT). Both theories predict the same outcomes, such as increased achievement striving, sustained behavior change, and perceptions of well-being, but they differ in why those outcomes occur. AGT assumes that individuals cognitively evaluate the competence demands and meaningfulness of the activity, and that those perceptions govern behavior. SDT assumes that individuals are driven by three basic needs, competence, autonomy, and relatedness, and the satisfaction of those needs govern behavior. The following discusses both theories and concludes that each has their strengths and weaknesses.
