A study investigated the influence of users' attitudes and sources of information on their adoption of a training research project. A two-part questionnaire was administered to 111 Army participants attending TRADOC/FORSCOM Training and Evaluation Workshops to gather attitudinal and usage information relating to the adoption of the Training Extension Course (TEC) program by unit training managers. Sources of TEC-related information were matched with the awareness, acceptance, and utilization stages of the adoption process to gain an understanding of the dissemination activity within training technology transfer. Two major findings emerged. The acceptance (persuade stage) of the TEC program was influenced primarily by internal sources of information, while the initial awareness (inform stage) and later utilization of TEC were influenced by internal and external sources. Prior familiarity with TEC predicted TEC usage better than did attitudinal measures (for this particular sample). However, familiarity alone did not insure extensive TEC usage, since about half of those previously familiar with TEC did not use it. Findings suggested that periodic scheduled TEC assessments might increase TEC use and that job performance data should continue to be collected for evaluating TEC utilization.
