This is a study of the validity of the Rosenberg Self-Esteem Scale in predicting first-year student involvement in extracurricular social and athletic activities during the 1981 summer session at Bowling Green State University in Ohio. A total of 14 males and 13 females completed the Rosenberg Scale and an 8-item questionnaire concerning their participation in extracurricular activities. When the Rosenberg Scale was scored using a Likert-type method, significant correlations appeared among the self-esteem score, the number of new friends met at college, and the number of social functions and contacts subjects had during an average week. No correlation was found between self-esteem and membership in clubs and organizations or extracurricular athletic activities. Since the study used such a small number of summer quarter first-year students, who were not necessarily representative of first-year college students as a population, the results cannot be generalized to all first-year students. Further study of the use of Likert-type instruments to control for social desirability among subjects is recommended. (TJH)
