Identity Development

Identity development is a stage in the adolescent life cycle. For most, the search for identity begins in the adolescent years. During these years, adolescents are more open to ‘trying on’ different behaviors and appearances to discover who they are. In an attempt to find their identity and discover who they are, adolescents are likely to cycle through a number of identities to find one that suits them best. Developing and maintaining identity (in adolescent years) is a difficult task due to multiple factors such as family life, environment, and social status. Empirical studies suggest that this process might be more accurately described as identity development, rather than formation, but confirms a normative process of change in both content and structure of one’s thoughts about the self.


Two main aspects of identity development are self-concept and self-esteem. The idea of self-concept is known as the ability of a person to have opinions and beliefs that are defined confidently, consistently and with stability. Early in adolescence, cognitive developments result in greater self-awareness, greater awareness of others and their thoughts and judgments, the ability to think about abstract, future possibilities, and the ability to consider multiple possibilities at once. As a result, adolescents experience a significant shift from the simple, concrete, and global self-descriptions typical of young children; as children they defined themselves by physical traits whereas adolescents define themselves based on their values, thoughts, and opinions.

Adolescents can conceptualize multiple “possible selves” that they could become and long-term possibilities and consequences of their choices. Exploring these possibilities may result in abrupt changes in self-presentation as the adolescent chooses or rejects qualities and behaviors, trying to guide the actual self toward the ideal self (who the adolescent wishes to be) and away from the feared self (who the adolescent does not want to be). For many, these distinctions are uncomfortable, but they also appear to motivate achievement through behavior consistent with the ideal and distinct from the feared possible selves.

Further distinctions in self-concept, called “differentiation,” occur as the adolescent recognizes the contextual influences on their own behavior and the perceptions of others, and begin to qualify their traits when asked to describe themselves. Differentiation appears fully developed by mid-adolescence. Peaking in the 7th-9th grades, the personality traits adolescents use to describe themselves refer to specific contexts, and therefore may contradict one another. The recognition of inconsistent content in the self-concept is a common source of distress in these years, but this distress may benefit adolescents by encouraging structural development.


Another aspect of identity formation is self-esteem. Self-esteem is defined as one’s thoughts and feelings about one’s self-concept and identity. Most theories on self-esteem state that there is a grand desire, across all genders and ages, to maintain, protect and enhance their self-esteem. Contrary to popular belief, there is no empirical evidence for a significant drop in self-esteem over the course of adolescence. “Barometric self-esteem” fluctuates rapidly and can cause severe distress and anxiety, but baseline self-esteem remains highly stable across adolescence. The validity of global self-esteem scales has been questioned, and many suggest that more specific scales might reveal more about the adolescent experience. Girls are most likely to enjoy high self-esteem when engaged in supportive relationships with friends, the most important function of friendship to them is having someone who can provide social and moral support. When they fail to win friends’ approval or can’t find someone with whom to share common activities and common interests, in these cases, girls suffer from low self-esteem.

In contrast, boys are more concerned with establishing and asserting their independence and defining their relation to authority. As such, they are more likely to derive high self-esteem from their ability to successfully influence their friends; on the other hand, the lack of romantic competence, for example, failure to win or maintain the affection of the opposite or same-sex (depending on sexual orientation), is the major contributor to low self-esteem in adolescent boys.

Identity Formation: Who am I?

Adolescents continue to refine their sense of self as they relate to others. Erik Erikson referred to life’s fifth psychosocial task as one of identity versus role confusion when adolescents must work through the complexities of finding one’s own identity. Individuals are influenced by how they resolved all of the previous childhood psychosocial crises and this adolescent stage is a bridge between the past and the future, between childhood and adulthood. Thus, in Erikson’s view, an adolescent’s main questions are “Who am I?” and “Who do I want to be?” Identity formation was highlighted as the primary indicator of successful development during adolescence (in contrast to role confusion, which would be an indicator of not successfully meeting the task of adolescence). This crisis is resolved positively with identity achievement and the gain of fidelity (ability to be faithful) as a new virtue, when adolescents have reconsidered the goals and values of their parents and culture. Some adolescents adopt the values and roles that their parents expect for them. Other teens develop identities that are in opposition to their parents but align with a peer group. This is common as peer relationships become a central focus in adolescents’ lives.

Expanding on Erikson’s theory, Marcia (1966)[1]) described identity formation during adolescence as involving both decision points and commitments with respect to ideologies (e.g., religion, politics) and occupations. Foreclosure occurs when an individual commits to an identity without exploring options. Identity confusion/diffusion occurs when adolescents neither explore nor commit to any identities. Moratorium is a state in which adolescents are actively exploring options but have not yet made commitments. As mentioned earlier, individuals who have explored different options, discovered their purpose, and have made identity commitments are in a state of identity achievement.

Developmental psychologists have researched several different areas of identity development and some of the main areas include:

  • Religious identity: The religious views of teens are often similar to those of their families (Kim-Spoon, Longo, & McCullough, 2012) [2] Most teens may question specific customs, practices, or ideas in the faith of their parents, but few completely reject the religion of their families.
  • Political identity: An adolescent’s political identity is also influenced by their parents’ political beliefs. A new trend in the 21st century is a decrease in party affiliation among adults. Many adults do not align themselves with either the democratic or republican party and their teenage children reflect their parents’ lack of party affiliation. Although adolescents do tend to be more liberal than their elders, especially on social issues (Taylor, 2014) [3], like other aspects of identity formation, adolescents’ interest in politics is predicted by their parents’ involvement and by current events (Stattin et al., 2017). [4]
  • Vocational identity: While adolescents in earlier generations envisioned themselves as working in a particular job, and often worked as an apprentice or part-time in such occupations as teenagers, this is rarely the case today. Vocational identity takes longer to develop, as most of today’s occupations require specific skills and knowledge that will require additional education or are acquired on the job itself. In addition, many of the jobs held by teens are not in occupations that most teens will seek as adults.
    Identity spectrums: Sex, Gender Identity, Gender Expression, and Sexual Orientation. The Continuum for sex shows female on one side, male on the other side, and intersex in between. Continuum for gender identity shows woman on one side, man on the other side, and genderqueer in between. Continuum for gender expression shows feminine on one side, masculine on the other side, and androgynous in between. Continuum for sexual orientation shows “Attracted to male” on one side, “attracted to female” on the other side, and Bisexual, Pansexual, and Asexual in between.

    Figure 2. This identity spectrum shows the fluidity between sex, gender identity, gender expression, and sexual orientation.

  • Ethnic identity: Ethnic identity refers to how people come to terms with who they are based on their ethnic or racial ancestry. According to the U.S. Census (2012) more than 40% of Americans under the age of 18 are from ethnic minorities. For many ethnic minority teens, discovering one’s ethnic identity is an important part of identity formation. Phinney (1989)[5] proposed a model of ethnic identity development that included stages of unexplored ethnic identity, ethnic identity search, and achieved ethnic identity.
  • Gender identity: A person’s sex, as determined by his or her biology, does not always correspond with his or her gender. Sex refers to the biological differences between males and females, such as the genitalia and genetic differences. Gender refers to the socially constructed characteristics of women and men, such as norms, roles, and relationships between groups of women and men. Many adolescents use their analytic, hypothetical thinking to question traditional gender roles and expression. If their genetically assigned sex does not line up with their gender identity, they may refer to themselves as transgender, non-binary, or gender-nonconforming.
    • Gender identity refers to a person’s self-perception as male, female, both, genderqueer, or neither. Cisgender is an umbrella term used to describe people whose sense of personal identity and gender corresponds with their birth sex, while transgender is a term used to describe people whose sense of personal identity does not correspond with their birth sex. Gender expression, or how one demonstrates gender (based on traditional gender role norms related to clothing, behavior, and interactions) can be feminine, masculine, androgynous, or somewhere along a spectrum.
    • Fluidity and uncertainty regarding sex and gender are especially common during early adolescence, when hormones increase and fluctuate creating difficulty of self-acceptance and identity achievement (Reisner et al., 2016).[6] Gender identity, like vocational identity, is becoming an increasingly prolonged task as attitudes and norms regarding gender keep changing. The roles appropriate for males and females are evolving and some adolescents may foreclose on a gender identity as a way of dealing with this uncertainty by adopting more stereotypic male or female roles (Sinclair & Carlsson, 2013) [7]. Those that identify as transgender or other face even bigger challenges.

Gender Identity and Transgender Individuals

Individuals who identify with the role that is different from their biological sex are called transgender. Approximately 1.4 million U.S. adults or .6 percent of the population are transgender according to a 2016 report.[8]

Transgender individuals may choose to alter their bodies through medical interventions such as surgery and hormonal therapy so that their physical being is better aligned with gender identity. They may also be known as male-to-female (MTF) or female-to-male (FTM). Not all transgender individuals choose to alter their bodies; many will maintain their original anatomy but may present themselves to society as another gender. This is typically done by adopting the dress, hairstyle, mannerisms, or other characteristic typically assigned to another gender. It is important to note that people who cross-dress, or wear clothing that is traditionally assigned to a different gender is not the same as identifying as trans. Cross-dressing is typically a form of self-expression, entertainment, or personal style, and it is not necessarily an expression against one’s assigned gender (APA 2008).

After years of controversy over the treatment of sex and gender in the American Psychiatric Association Diagnostic and Statistical Manual for Mental Disorders (Drescher 2010), the most recent edition, DSM-5, responds to allegations that the term “gender identity disorder” is stigmatizing by replacing it with “gender dysphoria.” Gender identity disorder as a diagnostic category stigmatized the patient by implying there was something “disordered” about them. Gender dysphoria, on the other hand, removes some of that stigma by taking the word “disorder” out while maintaining a category that will protect patient access to care, including hormone therapy and gender reassignment surgery. In the DSM-5, gender dysphoria is a condition of people whose gender at birth is contrary to the one they identify with. For a person to be diagnosed with gender dysphoria, there must be a marked difference between the individual’s expressed/experienced gender and the gender others would assign him or her, and it must continue for at least six months. In children, the desire to be of the other gender must be present and verbalized (APA 2013).

Changing the clinical description may contribute to a larger acceptance of transgender people in society. A 2017 poll showed that 54 percent of Americans believe gender is determined by sex at birth and 32 percent say society has “gone too far” in accepting transgender people; views are sharply divided along political and religions lines.[9]

Studies show that people who identify as transgender are twice as likely to experience assault or discrimination as nontransgender individuals; they are also one and a half times more likely to experience intimidation (National Coalition of Anti-Violence Programs 2010; Giovanniello 2013). Trans women of color are most likely be to victims of abuse. A practice called “deadnaming” by the American Civil Liberties Union, whereby trans people who are murdered are referred to by their birth name and gender, is a discriminatory tool that effectively erases a person’s trans identity and also prevents investigations into their deaths and knowledge of their deaths.[10] Organizations such as the National Coalition of Anti-Violence Programs and Global Action for Trans Equality work to prevent, respond to, and end all types of violence against transgender and homosexual individuals. These organizations hope that by educating the public about gender identity and empowering transgender individuals, this violence will end.
