In one of her studies, Pietromonaco and other researchers investigate how attachment styles of couples affect their cortisol levels and risks of future mental health issues. It is suggested that couples with wives having the anxious attachment style and husbands having the avoidant attachment style stand more chances of developing depression and anxiety over time.^[4] Similarly, she and other researchers state that the attachment styles can affect how people behave and think during interpersonal conflicts.^[5][4] She has also emphasized in other studies that a partner plays an important part when a person faces a stressful event or has chronic diseases. Partners can help calm or can make recovery more difficult, depending on their behavior.^[4] In another study with college students, her team has found that responsiveness affects the intimacy of self-disclosure among couples.^{[citation needed]}
