Avoidant attachment style is also mediated by the satisfaction have effect on infidelity (indirect effect = 0.10, P < 0.01).

Agreeableness (indirect effect = 0.07, P < 0.05) and accountability (indirect effect = 0.08, P < 0.01) through satisfaction could also have a significant negative effect on the infidelity. Also Neuroticism (direct effect = 0.22, P < 0.01), extroversion (direct effect = 0.23, P < 0.01), the desire to experience (direct effect = 0.16, P < 0.01) is directly and positively, and responsibility as directly and negatively (direct effect = -0.16, P < 0.01) were effective against infidelity.
