The purpose of this study was to develop the Physical Activity Class Satisfaction Questionnaire (PACSQ). In Study 1, qualitative data were collected from 16 students. The results, coupled with a review of the relevant literature, helped to construct the various dimensions of satisfaction. In Study 2, a quantitative questionnaire was developed and administered to 194 students; based on the results, slight changes were made to the questionnaire. Additional data were then collected in Study 3 from 179 students to test the revised questionnaire. The PACSQ consists of nine dimensions of satisfaction: Mastery Experiences, Cognitive Development, Teaching, Normative Success, Interaction with Others, Fun and Enjoyment, Improvement of Health and Fitness, Diversionary Experiences, and Relaxation. The findings have implications for physical activity class instructors and for program managers. (Contains 2 tables.)
