The purpose of the present study was to investigate the relationship between family communication patterns (conversation orientation and conformity orientation) and communication skills of adolescents. Random multistage cluster sampling method was utilized and as a result 367 students including 232 girls and 135 boys were chosen from first and second graders of high school in District 1 of Tehran. The participants completed the Revised Family Communication Patterns Questionnaire" (Koerner & Fitzpartick، 2002) and the "Communication skills Questionnaire" (Queendom، 2004). For the purpose of data analysis، first Pearson correlation and simultaneous regression analysis were used in order to predict communication skills through dimensions of family communication patterns. Then according to high and low grades of dimensions of family communication patterns، four types of family were identified and the extent of students' communication skills in various family types was compared through one-way ANOVA. The regression analysis results indicated that the family conversation orientation has a significant، positive relationship with adolescents' communication skills and predicts it positively. In addition، family conformity orientation has a significant، negative relationship with adolescents' communication skills and predicts it negatively. The results of variance analysis were indicative of a significant difference between the groups and revealed that children of consensual and pluralistic families possess more communication skills compared to those of protective and laissez-faire families. These families focus on conversation and free، comfortable interaction between family members and in such families children learn how to establish healthy relationships in their family environment.
