Results: Based on the direct effect of anxiety attachment, emotional deprivation, abandonment, social isolation, failure and vulnerability schemas on Eros love style, and the direct effect of anxiety attachment style and social isolation schema on Storge's love style, were significant (P≥0/05). Also, emotional deprivation, vulnerability, self-sacrifice, and Eros, Storge and Agape love-making styles had a direct effect on marital intimacy (P≥0/05) and the direct effect of anxiety attachment, Storge love style, enmeshment, vulnerability, self-sacrifice schemas, and intimacy on marital infidelity were significant (P≥0/05).

Choosing spouse and entering into marriage is a turning point in the growth and character development. Certainly, the choice of partner is one of the most important decisions in life. The aim of this study was to determine the predictive value of marital adjustment through study of variables of attachment and determinism as predictors of marital adjustment. The study used a correlation method and conducted on a sample of 50 student couples from Kermanshah Branch, Islamic Azad University that was selected by convenience sampling. To collect data, the marital adjustment scale, attachment scale for adults, and deterministic thinking scale were used. Except for variables of avoidant attachment and overall deterministic thinking, which were not correlated with marital adjustment, other variables (secure attachment, ambivalent attachment, determinism in interaction with others, philosophical determinism, determinism in future anticipation, and determinism in tragic events) had significant relationships with marital adjustment. All the variables were also able to predict marital adjustment. Based on significant correlation of the components of this research, the findings can be used to improve the compatibility of couples.
