A study examined a group career decision-making treatment for community college students and attempted to determine the following: (1) the effects of group career decision-making skills, appropriateness of occupational choice, and frequency of information-seeking behavior; (2) the relationship between decision-making skills and the appropriateness of subjects' decisions; (3) the effect of the comprehensiveness and duration of a treatment; and (4) the effects of age, sex, and reading-level differences on career decision-making and on structured group interventions. Following a review of literature that found significant positive outcomes in many studies of group treatments, 39 students volunteered to take career decision-making courses in fall 1983 at a rural, open-admissions community college in the northeast. Two experimental groups received a longer treatment of 20 75-minute sessions for 10 weeks or a shorter treatment of 10 75-minute sessions lasting 5 weeks. The third group was in a no-treatment condition for 5 weeks and then received the longer treatment. The results favored the effectiveness of the longer treatment. Some significant age differences, favoring younger students, were noted, although sex and reading-level differences were negligible. The research encourages continued group approaches to career decision making, but warns about the limitation of short-term interventions and those that do not provide for individualization. (KC)
