Methods: In the present correlational study design, 303 cases of Shiraz secondary girl students who lived with their parents were chosen through the multistage random cluster sampling method. They responded to questionnaires for consistency of family, positives flexibility, Cooper Smith Self-esteem and Oxford Happiness scale. The data were analyzed by Pearson correlation and multiple regressions. Results Family consistency had significant positive power predictive for criterion variables self-esteem and happiness (p <0.05), whereas the flexibility had no such significance. Conclusion: Quality of operation of parents, communication and interaction in family life is one of the best determinants of behavior, health and well-being of children, including their self-esteem and happiness.

Seven relations enriching group training sessions were held for the spouses.  At the end of the training sessions, both groups were evaluated by emotional security questionnaires by Brunner et al. (2008), marital conflict Sanaei and Barati (1996).

Results: Covariance analysis and multivariate analysis of variance, analysis of the results of the marital conflict, mean and standard deviation of pre couples' marital conflict experimental and control groups were (20/15) and 20/145 (64/16) 70/143 respectively.  The test score in two groups were (60/12) and 80/64 (17.4) and 70/143 respectively. The results of multivariate analysis of covariance components of marital conflict on test scores of experimental and control groups and the control effect of pre-test showed that Pylayy effect, Wilks Lambda test, Hotelling effect on the root of F=4.47 and degrees of freedom 7 levels significantly in p=0.0001 Effect of married couples was significant in reducing aggression.
