Outcome expectancies Social-learning theory proposes two types of expectancies: –Self-efficacy –Outcome expectancies Other theories and models also use the outcome expectancies –Theory of reasoned action / theory of planned behavior models –Social-cognitive theory Recent research demonstrated that outcome expectancies mediate between antecedents like personality and drug-use behavior, including –alcohol ( e.g. Williams & Clark, 1998, Urbán et al., 2008) –marijuana (Vangsness,Bry, & LaBouvie, 2004 ) –cocaine use ( Stacy et al., 1995).

Outcome expectancies in the present research Negative consequences –long-term negative health consequences of smoking Positive/sensory reinforcement –expectancies of individual sensory satisfaction from smoking Negative reinforcement –expectancies regarding coping and negative emotion regulation through smoking Appetite and weight control –expectancies that smoking helps to manage appetite and weight (Short-term negative consequences) (Boredom reduction)

Budapest Adolescent Smoking Study Methodology

Fall 2008Spring 2009.Fall 2009Spring 2010Fall 2010 Longitudinal design Sampling method: cluster sampling Sampling unit: classes

Representative sample of the highschools in Budapest Sample 70 schools 106 classes (9th grade) The total number of participants: 3565 students (49.8 % boys and 50.2 % girls). Mean age 15.3 yrs (SD=0.56) in the first wave.

Data collection During a class hour Self-report questionnaire includes: –Question related to smoking, nicotine addiction, perceived parental attitude, peer smoking, parental smoking, etc. –The Short form of Smoking Consequences Questionnaire –A short form of Sensation Seeking questionnaire –Susceptibility to smoking scale for the nonsmokers –Tobacco Advertisement Receptivity scale –Alcohol use, physical activity –Depression (CESD) –Body image questions and many others

The role of expectancies in smoking initiation Are the outcome expectancies important before the experimentation with smoking?

Predictors of experimentation with smoking between Wave 1 and Wave 2 Negative consequences Positive reinforcement Negative reinforcement Appetite and weight control Susceptibility (intention) to smoking Trying smoking (0.022)*** (0.015 )** (0.016)*** 0.63 (0.016)*** R² =9% R² =18% χ ² =566.7 df=284; CFI=.933 TLI=.923 RMSEA=.032 [ ]; N=828. Based on students who had not tried smoking in Wave 1 and provided data in Wave 2 Unstandardized coefficients (SE)

The role of outcome expectancies in smoking initiation Expectancies are developed far before the experimentation with smoking. Thinking about the possible negative consequences can reduce the risk of smoking initiation. Thinking about the reinforcement properties of smoking can increase the intention to try and the risk of smoking initiation.

The role expectancies in smoking intensity Crosslagged analysis – an analysis of the cause and effect

Smoking intensity Smoking intensity is defined with –number of days smoked during the past 30 days –number of cigarettes smoked a day on average Smoking intensity is a rough estimation of the number of cigarettes during the past 30 days.

Conclusions Outcome expectancies are important factors in smoking initiation and smoking intensity in adolescents. Outcome expectancies are changing in time. In different age, the strength of these expectancies change. Targeting outcome expectancies is an important focus of prevention work, but one time shot might be not enough.
