were nearly 1010 father-mother-child teams investigated. The each participants (father, mother and student) were evaluated

by using The Differentiation of Self Inventory, The Family Triangulation Inventory and The General Health Questionnaire.

In the causal model, the influence of each parent’s self-differentiation on adolescent’s general health was observed by using

the adolescent’s self-differentiation as a mediator. Result indicated that, each parent’s self-differentiation positively affect the

adolescent’s self-differentiation which may also affect the adolescent general health. The effect of father’s and mother’s

self-differentiation on adolescent general health was observed to be similar. Our result also confirmed Bowen’s theory about

the intergenerational transmission of self-differentiation, and each parent’s self-differentiation positively affect the adolescent

general health. In the causal model, the influence of each parent’s self-differentiation on adolescent’s general health was

observed by using the family triangulation as a moderator and the adolescent’s self-differentiation as a mediator. Result

indicated that, in high score team the adolescent involved in the family triangulation affect in same way as the low score team

by which each parent’s self-differentiation influences adolescent self-differentiation. Thus the moderator effect of the family

triangulation was not supported.
