LOS ANGELES — In an age where swiping right has become the norm and staying single throughout your 20s is increasingly common, UCLA researchers have uncovered a surprising key to happiness for young adults without romantic partners: friendship satisfaction.
A recent study published in PLOS ONE sheds light on the complex world of single emerging adults, those between the ages of 18 and 24 who are navigating the tumultuous waters of early adulthood without a significant other. The research, led by Lisa C. Walsh and her colleagues, dives deep into what makes this demographic tick, revealing that the quality of friendships plays a crucial role in determining overall life satisfaction.
The study examined a diverse group of 1,073 single young adults in the United States, using a sophisticated statistical technique called latent profile analysis (LPA) to identify distinct subgroups based on various factors influencing happiness. These factors included friendship satisfaction, family satisfaction, self-esteem, neuroticism (tendency towards negative emotions), and extraversion (outgoing personality).
The results paint a nuanced picture of young singles, challenging the stereotype that all unattached individuals are miserable. In fact, the study found that nearly 38% of participants were relatively happy, while only about 24% were unhappy. This finding suggests that being single doesn’t automatically equate to a life of loneliness and despair.
However, what really stood out was the importance of friendships. The researchers identified five distinct profiles of single young adults, ranging from very happy to very unhappy. Across these profiles, friendship satisfaction emerged as a critical factor in distinguishing between the happy and unhappy groups.
For instance, the happiest group, making up about 11% of the sample, reported very high levels of friendship satisfaction along with other positive traits like high self-esteem and low neuroticism. On the other hand, the unhappiest group, comprising 9% of participants, had very low friendship satisfaction coupled with other negative factors.

Interestingly, the study found that young singles could often compensate for disadvantages in one area with strengths in others. For example, some individuals with higher levels of neuroticism (a trait often associated with anxiety and moodiness) still managed to be relatively happy if they had satisfying friendships and family relationships.
The study also touches on other factors influencing happiness among young singles. Family relationships, self-esteem, and personality traits all play a role, interacting in complex ways to shape overall life satisfaction. However, friendship satisfaction consistently emerged as a standout factor, often distinguishing between those who were happy and those who were not.
For young singles reading this, the message is clear: invest in your friendships. Those late-night conversations, weekend hangouts, and shared experiences with friends aren’t just fun – they’re contributing significantly to your happiness and well-being.
Paper Summary
Methodology
The researchers used latent profile analysis (LPA), a statistical technique that identifies subgroups within a population based on patterns of responses to multiple variables. They collected data from 1,073 single adults aged 18-24 in the United States using online surveys. Participants answered questions about their life satisfaction, friendship and family satisfaction, self-esteem, and personality traits (neuroticism and extraversion). The LPA then grouped participants into profiles based on similarities in their responses across these measures.
Key Results
The analysis revealed five distinct profiles of single young adults, ranging from very happy to very unhappy. The happiest group (11% of participants) had high scores across all positive measures and low neuroticism. The least happy group (9%) showed the opposite pattern. Importantly, friendship satisfaction emerged as a critical factor distinguishing between happy and unhappy profiles. The study also found that 37.9% of participants were relatively happy, while 23.7% were unhappy, challenging the stereotype that all singles are miserable.
Study Limitations
The study was cross-sectional, meaning it captured data at one point in time, making it impossible to determine causality. The sample was also limited to the United States, potentially limiting generalizability to other cultures. Additionally, the study only examined two personality traits (neuroticism and extraversion) and did not include other potentially relevant factors.
Discussion & Takeaways
The study highlights the crucial role of friendship satisfaction in the well-being of young singles. It suggests that strong friendships can compensate for challenges in other areas of life. The findings challenge the societal emphasis on romantic relationships as the primary source of happiness for young adults and suggest that cultivating strong friendships may be equally important for overall life satisfaction.
