The problem was to construct, validate, and test a Q-sort instrument consisting of 56 statements measuring attitude changes of individual participants toward the seven educational conditions of the Indiana Plan for Adult Education in the Church. The Q-sort was structured to represent conditions of the plan at two levels with four replications (7x2x4). Four populations were used to provide data on the instrument's reliability in a control group, its vulnerability to irrelevant response determiners, effects of participation in a training institute, and criteria associated with subjects well oriented to the plan. Trainers also nominated participants who had shown most and least change during the institute. Findings led to these conclusions: (1) the Q-sort did measure attitudes; (2) criterion subjects shared a common, distinctive pattern of attitudes toward the conditions of the Indiana Plan; (3) participation promoted significant changes in attitudes of participants; (4) the meaning of these attitude changes cannot be interpreted without further study, especially followup; (5) Q-sorts provide a means of studying phenomena of intrapersonal dynamics.
