Social intelligence plays an important role in multiple-intelligence. There is limited research about social intelligence evaluation in Taiwan. The goal of the present study was to adapt the Tromso Social Intelligence Scale (TSIS) to the digital library guide designers to evaluate the social intelligence in life skill. In addition to TSIS, computer self-efficiency scale was added to do related measurement. Besides, Kepner-Tregoe analysis (KTA) was used to collect designing scores and decide the final E-materials. Our analyses revealed good internal reliability, the correlation between TSIS and basic computer skill was high and applying KTA decided better digital library guide movies.
