The instruments used for this study were a Family support scale of Park, Jee Won, life-satisfaction scale of Wood, Wylie& Sheafer and Rosenberg`s Self-esteem Scale. The reliability of the scales were tested by Cronsbach`s Alpha. The collected data Were analyzed by the SPSS program using unpaired t-test and Pearson`s Correlation Coefficients. The results were as follows ; 1. There Was a statistically significant difference in the level of demographic between family support groups for the homeless at institutionalized residents : age (t=2.23, p=.028), education background (=5.53, p=.005), present illness(t=1.97, p=.052). emotion states(t=2.94, p=.041). 2. There Was a statistically significant difference in the level of demographic between family support groups for the homeless at noninstitutionalized residents : types of disease(t=1.55, p=.161). 3. There Was a statistically significant difference in the level of demographic between self-esteem groups for the homeless at institutionalized residents : types of disease(t=3.23, p=.004). 4. There Was a statistically significant difference in the level of demographic between self-esteem groups for the homeless at noninstitutionalized residents : use of drugs(t=-3.23 p= .002), types of disease(t=3.23, p=.004). 5. There Was a statistically significant difference in the level of demographic between life-satisfaction groups for the homeless at institutionalized residents : education background (t=3.11, p= .048), types of disease(t=3.40, p=.007), emotion states(t=4.93, p=.004). 6. There Was a statistically significant difference in the level of demographic between life-satisfaction groups for the homeless at noninstitutionalized residents : smoking (t=-2.31, p= .023), types of disease(t=2.07, p= .041), emotion states (t= 2.81, p= .049). 7. There was a positive correlation between family support and self-esteem for the institutionalized homeless and it was statistically significant (r=.443, p= .001). 8. There was a positive correlation between family support and life-satisfaction for the homeless at institutionalized residents and it was statistically significant (r= .389, p=.001). 9. There was a positive correlation between life-satisfaction and self-esteem for the homeless at institutionalized residents and it was statistically significant (r=.217, p= .02). 10. There wasn`t a correlation family support, self-esteem and life-satisfaction for the homeless at noninstitutionalized residents and it was statistically nonsignificant.
