Sixty-seven dietitians (N = 67) who participated in a talk-back television course in June 1981 were solicited for information to evaluate this method of continuing education. Responses (90%) supported data in the professional literature which specified that cost and distance deterred attendance at continuing education programs. Although problems such as technical difficulties and impersonal nature were identified with talk-back television, the majority of respondents (83%) gave it positive ratings and stated that they would participate in other such programs. Improvements need to be considered to enhance the attractiveness of this mode of learning for dietitians, but during the financial retrenchment of the 1980s, talk-back television appears to be supported as cost-effective and desirable.
1981年6月参加了电话交谈电视课程的67位营养师（N = 67）被征求意见，以评估这种继续教育方式。回复（90%）支持专业文献中的数据，这些数据表明成本和距离阻碍了参加继续教育项目。尽管电话交谈电视存在技术困难和缺乏人情味等问题，但大多数受访者（83%）给予了它正面评价，并表示他们会参加其他此类项目。需要考虑改进措施以提高这种学习方式对营养师的吸引力，但在20世纪80年代财政紧缩期间，电话交谈电视似乎因其成本效益高且令人满意而得到支持。
