Further examination of the reliability of the Modified Rathus Assertiveness Schedule.
The reliability of the 30-item Modified Rathus Assertiveness Schedule (MRAS) was examined using the test-retest method over a three-week period. The MRAS, which was administered to 103 white middle-class seventh graders, yielded correlations of .74 using the Pearson product and Spearman Brown correlation coefficient. The correlations for males yielded .77 and .72 using the Pearson Product and Spearman Brown techniques, respectively. For females the correlations for both tests were .72. Paired t tests by sex indicated no significant change in MRAS scores between test administrations. These findings add to the existing information on the reliability of the MRAS.
Four-year results of a youth smoking prevention program using assertiveness training.
Assertiveness training and its relationship to smoking behavior and how young adolescent boys and girls differ with respect to assertion was investigated. A total of 161 seventh-grade students from six health education classes participated. Two classes received an innovative smoking education program, two classes received assertiveness training plus an innovative smoking education program, and two classes received only the smoking education program usually offered by the school. Locus of control and levels of assertion and smoking behavior were assessed at pre- and posttest. The results indicate that boys are significantly more assertive than girls at age 12 (p = .0018), and this assertiveness increases equally over the next four years (p less than .0001). There were no significant differences in smoking behavior among the three groups; however, trends in smoking behavior in the desired direction were observed. There is no significant difference in smoking behavior between boys and girls. In this respect the sexes have reached equality, that is, girls are initiating cigarette smoking as frequently as are boys. Finally, there were no significant changes in assertion among the groups. It is concluded that the utility of assertiveness training for young adolescents is questionable.
