Intimacy vs. Isolation: Psychosocial Development in Adulthood

Erik Erikson introduced his theory of the stages of psychosocial development in the 1950s. It was built on Freud’s theory of psychosexual development, expanding it from the emotional and physical skills of early childhood to include the influence of social dynamics and carrying it into the stages of adulthood.

Erikson proposed the following eight stages. Each stage occurs sequentially and builds on the previous stages.

• Trust vs. Mistrust
• Autonomy vs. Shame and Doubt
• Initiative vs. Guilt
• Industry vs. Inferiority
• Identity vs. Role Confusion
• Intimacy vs. Isolation
• Generativity vs. Stagnation
• Ego Integrity vs. Despair

In this article, we will focus on Erikson’s sixth stage of psychosocial development—intimacy vs. isolation.—This intimacy stage centers on the idea that, with age, humans rely on each other for support in increasingly complex ways. While earlier stages of development are characterized by parent-child bonding and social learning, young adults are tasked with building robust social support networks that include family members, friends, and romantic partners.

What is the intimacy vs. isolation stage?

During early adulthood and young adulthood, the stage of intimacy versus isolation means the core developmental task for this age group is to form close relationships without losing their sense of self-identity. iIndividuals seek connections with friends, family, and romantic partners, built on the emotional, psychological, and sometimes physical intimacy that engenders mutual care and trust. Without close relationships, individuals may struggle with isolation—and the loneliness that often follows— well into middle adulthood and beyond. In addition to being harmful to mental health, social isolation is associated with a range of negative physical, socioeconomic, and quality-of-life outcomes, highlighting the benefit of individuals establishing close, lasting relationships.

What intimacy looks like in adulthood

Intimacy in adulthood may be most commonly associated with romance and committed relationships, but there can be many ways to make meaningful connections during this time.

Emotional and physical intimacy

Deep intimacy can rely on many factors, including emotional closeness and physical affection. Feeling comfortable sharing one’s innermost thoughts and feeling genuinely seen and supported can be key factors in establishing intimate connections in any type of relationship. 

Physical affection can be essential to romantic connections, and while it’s not a necessity for platonic relationships, a hug, a pat on the back, or a squeeze of the hand can help build strong friendships. Research shows that touch can have multiple benefits, including improving mental and physical well-being. 

Skills that support intimacy

Various skills can help support intimacy in adulthood, including:

• Self-awareness: Understanding your own emotions, needs, and boundaries can allow you to engage with others safely and openly.
• Emotional stability: Being able to manage difficult feelings may help you stay present and open in close relationships, even if things get challenging.
• Paced self-disclosure: Sharing personal details slowly can build trust over time, creating an environment where both people feel comfortable opening up to one another.
• Empathy: Recognizing and responding to what the other person is experiencing can deepen connections and help them feel genuinely understood.
• Communication skills: Being able to express one’s needs, feelings, and boundaries clearly and respectfully can be key to maintaining healthy connections.
• Trustworthiness: Consistently showing up and following through to friends and loved ones can help create a sense of safety that allows intimacy to grow.

What isolation looks like in adulthood

If the intimacy versus isolation stage is not resolved successfully, it can have various negative impacts on a person’s overall well-being well into adulthood. Below, we explore how isolation may appear and what can happen as a result of prolonged isolation.

Emotional and social isolation examples

Isolation can take many forms in adulthood, and it may not always be obvious. Even people who have relationships can feel isolated, whether it’s feeling emotionally distant from a romantic partner, disconnected from friends, or unsupported by family members. In cases where it may be difficult to recognize emotional isolation, some signs to look out for may include having a difficult time trusting others, feeling disconnected from friends and family, or feeling misunderstood.

Consequences of prolonged isolation

Improperly resolving the intimacy versus isolation conflict can lead to a variety of consequences that can go well beyond loneliness. For example, one study that looked at the effects of isolation during the COVID-19 lockdowns had numerous consequences, including:

• Depression
• Anxiety
• Increased stress levels
• Difficulties in emotion regulation

The emotional distance that may result from isolation can also make it difficult to maintain relationships and start new ones, increasing the risk that one may develop despair or other mental health challenges later in life.

Why intimacy matters for health and well-being

Research has shown that the quality of our close relationships can have significant effects on our lives. Below, we look at the many benefits of successfully resolving the intimacy vs isolation stage.

Physical and mental health benefits of intimacy

One of the significant benefits of intimacy is its impact on emotional well-being, including acting as a protective factor against mental illness. Romantic relationships, in particular, can have many benefits for mental health. According to one study, “Relationship science has also consistently demonstrated that romantic relationships are a key determinant of greater well-being in general... Specifically, satisfying romantic relationships are a key source of social-need fulfillment and support, which tend to predict better well-being and can buffer partners from negative mental-health outcomes.”

However, romantic relationships are not the only ones that can benefit mental health. Other research shows that family intimacy can be protective against depressive symptoms, and adult friendships can impact well-being, protecting against anxiety and depression. 

According to a 2024 study, strong relationships can also impact physical health, including the following: 

• Social isolation and loneliness seem to be linked with an increased risk for coronary heart disease and stroke.
• Low social connection and loneliness have also been associated with a higher risk for hypertension.
• Social connection can have a positive influence on the management and overall health of people with type 1 and type 2 diabetes.
• Evidence also suggests that poor social connections can be associated with worse outcomes in people who are already ill.

Factors that influence intimacy vs. isolation outcomes

While each individual’s experience with social isolation and loneliness may be unique, there are a number of risk factors for isolation to be aware of, including the following: 

• Mental or physical health issues: Chronic illnesses, disabilities, and mental health disorders like depression and anxiety can limit an individual’s ability to engage socially. These conditions can also affect personality traits that can impact a person’s ability to build and maintain social connections.
• Lack of mobility: Social isolation is a common concern among those who are aging, injured, disabled, or who lack reliable access to transportation. This effect may be more pronounced in rural areas where access to supportive social networks may be limited.
• Language barriers: Individuals who do not speak the predominant language of their community may struggle to communicate and build relationships.
• History of violence or abuse: Social isolation and loneliness tend to be more common among people with a history of violence, abuse, or other types of trauma. These experiences can be particularly damaging early in life, as they can affect healthy personality development.
• Unemployment: Unemployed individuals generally have fewer opportunities to interact with others and may lack the financial means to socialize. 
• Divorce or separation: The end of a significant, once-loving relationship can lead to losing social networks, as mutual friends may choose sides or drift away.
• Living alone: Those who live alone—particularly older adults—typically have fewer social interactions, making it important to maintain contact with friends, family, and neighbors.
• Low income: Financial constraints can limit access to social activities, transportation, and resources, facilitating social interaction. In addition, low-income areas often lack ample community resources.

How to build intimacy and overcome isolation

Due to the negative effects of social isolation and loneliness, those struggling with social isolation may benefit from seeking ways to connect meaningfully with others to develop intimacy. Even for those with plenty of social connections and successful relationships, establishing connections with neighbors and acquaintances who may be lonely or lack robust support networks could be a helpful way to branch out and help others overcome isolation. 

Join local clubs and groups

Community centers, faith organizations, professional associations, local clubs, and sports leagues can be valuable sources of meaning, fulfillment, and social connectedness. Browse local forums and community bulletin boards to learn about these groups. As you meet new people, you can exchange contact information and begin building your network.

Use online platforms

The internet offers no shortage of opportunities to build social relationships. Consider joining local Facebook groups, Reddit forums, or Discord servers, or using a platform like Meetup.com to find local events and gatherings near you. Online communities can also be a source of social engagement in their own right, allowing you to connect with others who share your interests.

Maintain regular contact

Keep in touch with family, friends, and neighbors, and keep the lines of communication open with new friends and acquaintances. To keep the connection alive, you might exchange texts or voice notes, phone or video calls, or plan to see each other in person. 

Volunteer

In addition to helping you engage more meaningfully with your community, volunteering can be a way to meet new people and grow your social network. Consider which causes you’re most passionate about and look for local organizations that offer volunteer opportunities in those areas.

Seek support

Loneliness and social isolation can be damaging to mental health in various ways, such as hindering personal growth and emotional stability. If you’re struggling, don’t hesitate to ask for help—speaking to a mental health professional can provide emotional support and guide you in practical strategies to overcome these challenges and grow your social network. Your therapist can help you practice self-disclosure, identify any issues that may be contributing to your loneliness, and create a workable plan for increasing your social support system and building intimacy in your existing relationships. 

If you face barriers to finding a therapist in your area, you can also try online therapy through a platform like BetterHelp. With an online platform, you can attend one-on-one sessions with your therapists and receive access to counselor-led group sessions, guided journaling, digital therapy worksheets, and other features. In addition, you can choose the format of therapy you prefer, whether via phone, video, or live chat. Research has found that online therapy for loneliness can lead to lasting improvements in mental health—even years after treatment concludes.
