Attitude changes of students participating in two community service programs at the University of Minnesota were evaluated using the semantic differential technique. Program I, a single day clinical experience at a state institution for the mentally retarded, involved 170 students; Program II, a 1-week clinical program in dental auxiliary utilization, involved 30 students. For each program, semantic differentials were designed to elicit scaled evauative responses toward concepts such as mental retardation and dentistry which were important to program objectives. Scales were administered in a pretest, post-test design. Statistically significant differences were noted for seven of eight target concepts, and appropriate attitude changes were inferred from these differences. Design of community programs and evaluation of desired attitude change using the semantic differential were discussed.
采用语义差异技术对明尼苏达大学参与两项社区服务项目的学生的态度变化进行了评估。项目一为在一家州立智障机构进行的单日临床体验，有170名学生参与；项目二是为期1周的牙科辅助应用临床项目，有30名学生参与。针对每个项目，设计了语义差异量表，以引出对诸如智障和牙科等对项目目标很重要的概念的量表评价反应。量表采用前测、后测设计进行施测。在八个目标概念中的七个上发现了具有统计学意义的差异，并从这些差异中推断出了适当的态度变化。文中讨论了社区项目的设计以及使用语义差异对期望的态度变化进行评估。
