Jøsendal, O. & Aarø, L. E. (2012). Adolescent smoking behavior and outcome expectancies. Scandinavian Journal of Psychology 53, 129–135. Adolescent smoking behavior is assumed to be associated with smoking outcome expectancies. Results in this paper are based on data from the control group of two data collections among Norwegian secondary school students taken approximately 30 months apart (T1 and T2). The dimensionality of smoking outcome expectancies was the same at both time points, revealing three components (“Addicted”, “Not harmful” and “Social”). After correction for attenuation, the Pearson’s correlation between T1 and T2 was 0.41 for the total sumscore, indicating low to moderate relative stability. When examining smoking expectancy sumscore means by smoking habits at T1 and T2, never smokers were different from smokers on both occasions. Never smokers scored low on “Social” and “Not harmful”, and high on “Addictive”. All associations were statistically significant ( p < 0.001). The “Social” dimension was the strongest predictor of smoking behavior at T1 and T2. One of the outcome expectancy sumscores (“Addictive”) at T1 predicted smoking habits at T2 after controlling for smoking habits at T1 ( p < 0.01). This predictor was significant also after entering outcome expectancy sumscores at T2 into the model ( p < 0.05). These results indicate that outcome expectations other than the health‐related ones should be paid attention to when planning new prevention programs.
