A diabetes education videotape was designed and pilot tested in a sample of 30 Spanish-speaking Hispanic diabetic adults in a rural Texas-Mexico border community. The videotape provided an overview of diabetes, with emphasis on the concept of blood glucose; relationships between food, medications, exercise, and blood glucose levels; and blood glucose monitoring. Outcomes of videotape effectiveness were based on a 20-item knowledge test and interview data to assess acceptability of videotapes as a learning tool. Comparison of the knowledge test scores of the experimental group (those who viewed the tape before taking the knowledge test) with the control group (those who took the test before viewing the tape) produced a positive, moderate effect size of 0.61. Interviews with subjects indicated enthusiastic acceptance of the videotape as a means of transmitting diabetes information.
