An evaluation of the effectiveness of a planned diffusion process: the Smoke-Free Class of 2000 project in Texas

The first year of the Texas Triagency Coalition Smoke-Free Class of 2000 project (SFC2000) in Texas was evaluated using a descriptive model developed from diffusion theory. Tobacco-prevention education (TPE) materials were to be made available to all first grade teachers within the state. A random sample survey of 213 teachers indicated that 96 (44.7%) had received the materials. Adoption and implementation were high. By May of 1989, 64.2% of those teachers receiving materials had adopted and already implemented the program, and 25.3% had adopted and intended to use the materials. Almost all (96.8%) of those teachers who received the kit indicated that they would maintain the first grade program in the coming school year. Of respondents to a 1 year follow-up survey, 41.1% used it the first year only, 27.3% used it both years, 12.5% used it only in year 2 and 18.2% did not use it either year. Of those receiving the kits, 48% indicated that they had not previously taught TPE and thus were introduced to the concept of TPE through the SFC2000 kits. Receptivity was highest (over 90% agreement) for including TPE in elementary school curricula, with fewer teachers strongly agreeing with items tapping personal involvement with TPE. This evaluation of a statewide component of a national initiative reinforces the need to consider the dissemination and implementation of materials when planning large-scale interventions and evaluating their impact.
