Analyses show that the intention to try to stop smoking was dependent not only on the perceived health benefit, but also on the subjects" confidence that they would succeed if they tried to stop.
As predicted by Weiner's [(1979). J . Educ. P s y c h o l . 71: 3-25] model of achievement motivation, those who attributed other smokers' failures at quitting to stable factors had lower expectancy of success, as had those who saw themselves as more addicted. When the follow-up data are considered, reported attempts at quitting were strongly related to previously declared intentions, and reported abstinence was related to previous confidence (expectancy of success) and perceived addiction.
Eiser and Sutton (1977) have argued that the decision facing the would-be quitter is not whether
to smoke or quit but whether to smoke or "try" to quit. The perceived consequences of quitting will not be the same as those of "trying" to quit if the smoker thinks that any such attempt is unlikely to succeed. Confidence, or what Bandura (1977) would call "self-efficacy," is thus a crucial mediating variable.
