#Neuroticism

A recent study has turned conventional wisdom on its head by revealing that conflict-driven behaviors—not simply a lack of positive gestures—are the main link between the personality trait of neuroticism and diminished relationship satisfaction. The findings shed critical light on how personality shapes emotional intimacy, and suggest new, targeted ways for couples in Thailand and beyond to build healthier, happier relationships.

Neuroticism, characterized by emotional instability, persistent worry, and mood swings, is common among the Thai population, just as it is globally. Traditionally, experts have advised couples to focus on increasing positive behaviors—small acts of kindness, frequent expressions of affection, and supportive communication. However, this week-long study, which tracked the daily behaviors of 246 participants, found that it is the prevalence of specific negative, conflict-driven acts, such as criticism or making a partner cry, that most strongly erodes satisfaction between romantic partners. Positive acts such as giving compliments were found to be beneficial but were not substantial enough to explain or offset the connection between neuroticism and dissatisfaction (Neuroscience News).

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.
