The attachment styles an individual forms while they are growing up can impact the type of relationships they form as adults. Research has shown insecure attachment styles can be correlated to substance abuse, emotional distress, and interpersonal problems. More specifically, this study focuses on the correlation between insecure attachment styles and substance abuse. Nineteen participants (nine male, ten female) between the ages of 18 to 32 were selected. Participants were given a 20-question survey that measured substance abuse and attachment styles. A t-test was conducted to compare the differences between participants who abuse substances and participants who do not abuse substances and as well as their attachment styles. These findings suggest there is a correlation between substance abuse and insecure attachment styles.
