  Relationships are vital for mankind in many aspects. According to Maslow
hierarchy of needs, it is suggested that while a healthy relationship is an
essential part of a human life that fundamentally determines our goals and
purposes, an unsuccessful relationship can lead to suicide and other major
psychological problems. However, a complete understanding of this topic still
remains a challenge and the divorce rate is rising more than ever before to
almost 50 percents. The objective of this research is to explore the
association between each group of behaviors by performing Bayesian network
analysis on a large publically available Experiences in Close Relationships
Scale, a test of attachment style survey (ECR) data from openpsychometrics
database. The resulting directed acyclic graph has 2 root nodes (Q02 from
avoidant and Q05 from anxious attachment) and 5 end nodes (Q16, Q34, and Q36
from anxious attachment). The network can be divided into 5 clusters, 2
avoidance and 3 anxiety clusters. Furthermore, our list of items in the
clusters are consistent with the findings of previous factor analysis studies
and our estimated coefficients are significantly correlated with those of one
partial correlation network study.
