This study was to determine the effect of an external health locus of control on smoking behavior mediated byknowledge about smoking in adolescent boys. The sampling technique was accidental sampling. Subjects were 110adolescents aged 15-20 years from Yogyakarta. Reliability test results demonstrate the scale of the external health locusof control has good reliability (α = 0.854), while a test of knowledge about smoking have KR-20 = 0.311 and scale α =0.405 smoking behavior, which means that two instruments are less reliable. In addition, the research data did not meetthe assumptions of normality (a = 0.005 < 0.05) and linearity that are required to analyze the data in path analysis. Thetest results with t-test showed that there were differences in external health locus of control (t = -0.913, p = 0.363; F =1.360, p = 0.204 > 0.05) and knowledge related to smoking (t = 1.572, p = 0.119; F = 1, 276, p = 0.261 > 0.05) amongregular and experiment smokers. Spearman correlation test results showed there is a correlation between smokingbehavior with external health locus of control (rs = 0.210, p = 0.027 < 0.05) but there is nota correlation betweensmoking behavior with knowledge related to smoking (rs = 0.155, p = 0.105 > 0, 05).
