In psychology, the theory of planned behaviour (TPB) is a theoretical model that links one’s beliefs and behaviour (Ajzen, 1991). Engagement in science refers to the extent of participation in scientific learning activities (Chang et al., 2007; Lin et al., 2013). This study used TPB to predict adult engagement in science in Taiwan. The data were collected from 1,657 citizens by survey interviews and quantitatively analysed. Results showed that adult interest in science had the antecedents of attitude toward science (β= 0.31, p < .001), self-concept in science (β= 0.11, p < .001), and self-efficacy in science (β= 0.20, p < .001). Meanwhile, adult interest in science had an effect on engagement in science (β= 0.26, p < .001). The Structural Equation Modelling showed that the above model had the acceptable model fits (CFI = .93; GFI = .92; RMSEA = .05; SRMR = .05). It is suggested that adults’ interest in science was the considerable factor to promote their engagement in science. Meanwhile, adults’ attitude toward science, self-concept in science, and self-efficacy in science were the crucial parts to promote their interest in science.
