Communicative capacities represent an important factor in psychosocial adaptation of the teenagers. As much as the values of communicative capacities grow, the more grow the values of the adaptation indicators, like: self acceptation, the acceptation of the others, the emotional convenience. There is a proportional direct correlation between teenager's adaptation and communicative styles, like: democratic style and conformist style; and between adaptation, authoritative style and conflictual style, is a reverse proportional correlation. As much as the teenagers have the communicative abilities better developed with the other teenagers and with grown-up persons, as more as easier they adjust to the new and unknown social conditions.
