Personality influences on change in smoking behavior

Area of Science:

• Psychology
• Public Health
• Behavioral Science

Background:

• Smoking remains a significant public health concern, particularly among young adults.
• Understanding the psychological factors associated with smoking initiation, persistence, and cessation is crucial for developing effective interventions.

Purpose of the Study:

• To examine the relationship between personality traits in early adulthood and changes in smoking status.
• To investigate how alterations in personality over time predict shifts in smoking behavior.

Main Methods:

• A prospective, longitudinal study of a general population birth cohort.
• Personality was assessed using the Multidimensional Personality Questionnaire at ages 18 and 26.
• Smoking status was recorded at ages 18, 26, and 32.

Main Results:

• Higher aggression and alienation at age 18 predicted smoking at age 26.
• Greater self-control and traditionalism at age 18 were associated with non-smoking at age 26.
• Increased alienation at age 26 predicted continued smoking up to age 32.
• Changes in personality between ages 18 and 26, specifically decreases in negative emotionality and increases in constraint, were linked to smoking cessation.

Conclusions:

• Personality traits and their changes are significant predictors of smoking behavior.
• Interventions targeting personality development, particularly reducing alienation and negative emotionality, may be effective for smoking cessation in young adults.
• Addressing potential resistance to antismoking messages in individuals with high alienation is a key area for future intervention strategies.
