What is the relationship between attachment avoidance and conformity?5 answersAttachment avoidance is associated with conformity. Avoidantly attached individuals have expectations of relationship failure and commitment aversion, which leads them to expect relationship failure. The coping strategy of attachment avoidance involves shutting down emotionally and masking one's feelings, which represents incongruence between emotional experience and expression. Incongruence is also a core aspect of repressive coping, which has been linked to potential long-term health risks. The relationship between attachment avoidance and conformity has not been extensively explored, but there is no agreement between the measures of attachment avoidance and conformity. Further research is needed to fully understand the relationship between attachment avoidance and conformity.
