Institute, and the National Institutes on Drug
Abuse, within the National Institutes of Health.
3Outcome 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).
4Outcome 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
- 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 (SD0.56) in the first wave.
8Data 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

experimentation with smoking?

13The 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.
14The role expectancies in smoking intensity
- Crosslagged analysis an analysis of the cause
and effect
15Smoking 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.

28Conclusions
- 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.
