Maintaining Friendships in Adulthood: What Psychology Research Describes
Adult friendships have substantial effects on wellbeing and longevity, but maintaining them across busy adult lives can be challenging. This summary pulls from psychology research, relationship resources, and published studies to describe what the research identifies as factors that support lasting friendships, common challenges adults face, and what approaches evidence supports.
This article does not claim personal experience with friendship challenges. The information below reflects what published psychology research and resources describe.
Why Friendships Matter for Adults
The CDC’s resources on social isolation and loneliness, along with substantial research summarized by the APA, document the health effects of social connection. Reviews consistently note that:
- Strong social connections are associated with reduced mortality risk.
- Social support buffers against stress-related health effects.
- Friendships provide distinct benefits from family relationships.
- Social isolation is associated with increased risk of mental and physical health conditions.
Reviews note that the size and quality of friendship networks vary substantially across individuals, with no single correct pattern.
What the Research Identifies as Supporting Lasting Friendships
Published research consistently identifies several factors associated with friendship maintenance:
Predictable contact patterns: Reviews consistently note that friendships with predictable contact patterns (a Sunday morning text, a quarterly call, an annual visit) tend to be more durable than friendships with unpredictable contact.
Brief but regular contact: Reviews note that brief regular contact (a 5-minute text exchange weekly) is often more sustaining than infrequent longer contact.
Shared activities: Reviews consistently note that group activities (shared games, group video calls, ongoing inside jokes) provide natural conversation prompts.
Acknowledgment of life transitions: Reviews note that friendships that explicitly acknowledge moves, jobs, family changes, and losses tend to weather those transitions better.
Asymmetric effort: Reviews consistently note that long-distance friendships are rarely maintained with symmetric effort, and that accommodating this asymmetry is associated with friendship longevity.
Reciprocity over time: Reviews note that friendships involve reciprocal support and engagement, though the form of reciprocity may vary.
Shared history: Reviews consistently note that shared history and accumulated experiences are important friendship resources, particularly for long-term friendships.
Common Challenges Adults Face
The published research consistently identifies several common challenges:
Time constraints: Reviews note that adult life often involves work, family, and other commitments that compete with friendship time.
Geographic distance: Reviews consistently note that adult lives often involve geographic moves that separate friends.
Life stage divergence: Reviews note that friends in different life stages (some with young children, others in demanding careers) may have less overlap in daily experiences.
Initiative imbalance: Reviews consistently note that one person often initiates more contact, which can lead to imbalance if unaddressed.
Life transitions: Reviews note that major life changes (marriage, parenthood, job changes, bereavement) can strain friendships.
Drift without explicit attention: Reviews consistently note that friendships can drift apart without specific events, simply from lack of attention.
Digital communication limits: Reviews note that text-based communication can maintain contact but doesn’t substitute for in-person connection for relationship depth.
What the Evidence Supports
Published research on friendship maintenance includes:
Predictable contact patterns: Reviews consistently note that scheduled contact patterns are associated with friendship longevity, with even brief contact maintaining connection.
Active listening and engagement: Reviews note that engaged, present attention during interactions is associated with better friendship quality than distracted interaction.
Vulnerability and authenticity: Reviews consistently note that friendships allowing vulnerability tend to deepen over time, while surface-level interactions plateau.
Support during difficulties: Reviews note that showing up during friends’ difficulties is associated with deeper long-term friendships.
Celebration of successes: Reviews consistently note that celebrating friends’ successes (rather than competing with them) is associated with better friendship quality.
Repair after ruptures: Reviews note that friendships that weather conflicts and repair ruptures are often stronger than those that avoid conflict.
What the Evidence Does Not Support
There are claims about friendship that outrun the evidence:
- That quantity of friends is the primary determinant of wellbeing. Reviews consistently note that friendship quality matters more than quantity.
- That any single approach works for all friendships. Reviews note that different friendships serve different purposes and have different patterns.
- That friendships should be effortless. Reviews consistently note that most lasting friendships require some effort and maintenance.
Common Difficulties
The published research consistently identifies several common difficulties:
Initiating contact: Reviews consistently note that many adults struggle to initiate contact, particularly if they perceive themselves as the lower-status friend or fear being intrusive.
Maintaining depth: Reviews note that without deliberate attention, friendships can become surface-level over time.
Conflict avoidance: Reviews consistently note that avoiding all conflict can lead to suppressed issues that eventually damage friendships.
Comparison and jealousy: Reviews note that comparing life trajectories can generate resentment that damages friendships.
Asking for help: Reviews consistently note that many adults struggle to ask friends for help, particularly during difficult times when help is most needed.
Considerations for Specific Life Stages
The published research consistently identifies life-stage considerations:
Early adulthood: Reviews note that post-college years often involve significant friendship changes as people establish careers and relationships.
Mid-life: Reviews consistently note that mid-life often involves balancing friendships with parenting and career demands.
Older adulthood: Reviews note that older adults often experience friendship changes due to retirement, relocation, and loss, with some research suggesting quality of remaining friendships becomes more important than quantity.
Life transitions: Reviews consistently note that major transitions (parenthood, divorce, job changes) often require deliberate friendship attention.
Common Approaches
Relationship resources consistently identify several approaches with reasonable evidence:
Scheduled contact: Reviews consistently note that scheduling regular contact (a weekly call, a monthly dinner) is associated with maintained friendships.
Group activities: Reviews note that activities with built-in regularity (recurring book clubs, sports leagues) maintain friendships through structure.
Communication rituals: Reviews consistently note that specific communication rituals (always texting on certain days, sharing specific types of content) support friendship maintenance.
Active listening: Reviews note that engaged attention during interactions is associated with better friendship quality than passive contact.
Repair attempts: Reviews consistently note that initiating repair after conflicts is associated with friendship longevity.
Vulnerability: Reviews note that allowing vulnerability deepens friendships, though this requires appropriate trust and reciprocity.
Combining Approaches
The published research consistently identifies that friendship maintenance interventions work best when combined with other practices:
Schedule + activities: Reviews consistently note that combining scheduled contact with shared activities is more effective than either alone.
Listening + vulnerability: Reviews note that combining engaged listening with appropriate vulnerability creates deeper friendships.
Initiative + acceptance: Reviews consistently note that one-sided initiative is exhausting, and that learning to accept others’ initiative is also important.
Online + in-person: Reviews note that combining online maintenance with periodic in-person contact is associated with better outcomes than either alone.
Considerations for Specific Friendships
The published research consistently identifies some friendship-specific considerations:
Childhood friends: Reviews note that these often involve shared history but may need active attention as life diverges.
Work friends: Reviews consistently note that workplace friendships can be valuable but require boundary considerations if work situations change.
Parent friends: Reviews note that friendships formed during parenthood often involve shared experiences but may narrow social networks.
Hobby friends: Reviews consistently note that activity-based friendships provide valued community but may have less depth in other life areas.
Long-distance friends: Reviews note that these require deliberate maintenance and benefit from regular in-person visits when possible.
When Professional Help Is Needed
Mental health resources consistently recommend professional evaluation when:
- Loneliness or social isolation is persistent and distressing
- Friendship difficulties are accompanied by other mental health concerns
- Social anxiety significantly limits friendship formation
- Relationship patterns repeat across multiple friendships in problematic ways
- Past trauma affects current friendship capacity
Reviews consistently note that therapy (particularly approaches addressing social anxiety, attachment, or family of origin) can support friendship-related concerns.
Limitations
Some limitations in the published research on adult friendships:
- Most studies are observational; experimental research on friendship maintenance is limited.
- Cultural variations in friendship expectations are not always well represented in the predominantly Western research base.
- Individual variation in friendship needs and patterns is substantial.
- Long-term effects of friendship interventions are less studied than cross-sectional associations.
