A new study suggests that frequent conflicts, such as arguments and emotional outbursts, may explain why individuals who score high in neuroticism tend to feel less satisfied in their romantic relationships. The research, published in Sexual and Relationship Therapy, unveils behavioral patterns that could be especially relevant for couples in Thailand seeking to strengthen their partnerships or understand why tensions sometimes run high (PsyPost).
Neuroticism, one of the Big Five personality traits studied worldwide, refers to a tendency to experience strong negative emotions—including anxiety, sadness, irritability, and emotional instability. While deeply influenced by genetics and early life experiences, this trait is not entirely unchangeable. Thai readers may be familiar with the trait as “hua jai wawn” in popular culture, describing people who are quick to be upset or easily distressed. International studies have long linked high neuroticism to poorer relationship outcomes, but the new research adds clarity by showing that it’s not just the emotional temperament itself but the tendency to engage in conflict-fueled behaviors that erode relationship satisfaction.
The research, led by a group in the United States, surveyed 202 adults who had been in committed, cohabitating relationships for at least a year. Participants completed daily diaries for one week, reporting on their feelings of relationship satisfaction and documenting whether they had engaged in any of 64 described behaviors—ranging from showing gratitude to expressing anger. At the beginning and end of the week, they also assessed their overall relationship satisfaction using standard psychological scales, and filled out a personality inventory capturing levels of neuroticism.
Researchers grouped everyday behaviors into two broad categories: positive actions such as showing affection or gratitude, and negative actions such as expressing anger, isolating oneself, or insulting one’s partner. Notably, the researchers identified a subset of negative behaviors they called “conflict tactics,” including yelling, unresolved arguments, and withdrawing emotionally.
Their statistical analysis showed that individuals higher in neuroticism did engage more often in negative behaviors and specifically in dysfunctional conflict tactics like yelling and arguing. Importantly, these negative behaviors—not the absence of positive actions—were responsible for the lower relationship satisfaction reported by neurotic individuals. According to the study authors, “Our research suggests that neuroticism is associated with more frequent negative relational behaviors, and specifically poorer conflict management behaviors. We also found that these behaviors alone decrease relationship satisfaction, but that they also are mechanisms through which neuroticism works to decrease relationship satisfaction.”
This research provides new insight for understanding couples’ dynamics in Thailand, where harmonious relationships and effective conflict resolution are highly valued cultural ideals. Thai Buddhist teachings often emphasize emotional balance and self-control, yet the reality of modern relationships may include pressures that make emotional outbursts more common, especially among individuals with underlying tendencies toward neuroticism. While the study did not include data from participants’ partners, and so could not assess how a partner’s reactions might influence outcomes, it still offers an important starting point for couples hoping to break cycles of conflict.
Experts in relationship psychology highlight that the study underscores the importance of conflict management, rather than simply increasing positive relationship actions. As the research relied on self-reported diaries over one week, the link between personality and daily behaviors appears to be robust. “Conflict is natural in every relationship, but how it is handled can make all the difference,” notes a family counselor at the Department of Mental Health in Thailand. “If you notice frequent arguments or emotional outbursts, it may be helpful to seek guidance on healthier conflict resolution strategies.”
The findings have meaningful implications for Thai couples and marriage counselors. Many Thai families may avoid discussing conflict openly, or may encourage individuals to suppress negative feelings to keep the peace—a practice that can backfire if it leads to long-term resentment and eventual outbursts. By understanding that patterns of conflict escalation and withdrawal are linked to ingrained personality traits, individuals can approach therapy or self-improvement with greater self-compassion and realism.
Cultural context is also vital. Thailand’s collectivist society often values group harmony and patience, yet Western influences and urban stressors are making direct confrontations slightly more common among younger couples. The study’s focus on conflict tactics suggests that while showing love and gratitude are valuable, addressing the root causes of frequent arguments—and learning constructive ways to express discontent—are critical for relationship longevity.
Looking ahead, the study raises questions for future research and practice. How might partners’ behaviors moderate the link between neuroticism and relationship satisfaction? Would interventions focused on improving emotional regulation and conflict management produce lasting improvements for both partners? For Thai couples, workplace stress, economic uncertainty, and shifting gender roles may all contribute to the frequency and intensity of conflicts. Expanding research to include dyadic (both partners) perspectives within Thai samples could yield culturally tailored strategies for marriage enrichment programs.
For Thai readers, the practical takeaway is twofold: first, recognize that frequent fights and emotional conflicts matter more to relationship happiness than simply not expressing affection; and second, seeking support—whether through counseling, meditation, or communication workshops—can help reduce negative conflict patterns. Mindfulness practices popularized through temples and wellness centers in Thailand have shown promise for emotional regulation, and integrating these with modern conflict management techniques may offer unique benefits for local couples.
For those living in Bangkok or bustling cities, relationship counseling services are becoming more accessible, with some hospitals and foundations offering affordable therapy in Thai language. Rural communities can benefit from online resources and community workshops focusing on communication, emotion management, and partner support.
In summary, while personality traits like neuroticism are part of our biological and psychological makeup, their impact on relationships can be mitigated by awareness and intentional behavioral change. Thai couples who find themselves in frequent disputes can take heart—there are proven pathways to greater satisfaction, rooted in both global science and Thai wisdom.
