In a recent study, researchers followed 437 middle-aged couples who were married between 4−6 years. Both were asked to fill out an introversion scale (e.g., I am often anxious about approaching people). They also filled out a martial satisfaction scale, which assessed their satisfaction towards various dimensions of their relationship. The study found a negative correlation between both variables. For both males and females, having an introverted partner decreased marital satisfaction in the other partner. In contrast, having a partner who was more extroverted increased marital satisfaction in the other partner. From these findings, the researchers suggest that introverted partners must learn to overcome their anxieties to maintain a healthy marriage.
