From willingness to intention: experience moderates the shift from reactive to reasoned behavior

Area of Science:

• Developmental Psychology
• Behavioral Science
• Adolescent Health

Background:

• Understanding proximal antecedents to risk behaviors is crucial for developing effective interventions.
• Behavioral intention (BI), behavioral expectation (BE), and behavioral willingness (BW) are key theoretical constructs.
• The predictive validity of these constructs may change across adolescent development.

Purpose of the Study:

• To compare the predictive validity of BI, BE, and BW for adolescent risk behaviors across different developmental stages.
• To examine how experience with risk behaviors influences the predictive power of these antecedents.
• To investigate the developmental shift in cognitive processing underlying risk behavior initiation and maintenance.

Main Methods:

• Three studies were conducted involving adolescent participants.
• Longitudinal data were collected on substance use, smoking, and class skipping.
• The predictive validity of BI, BE, and BW for changes in these behaviors was statistically analyzed.

Main Results:

• Behavioral willingness (BW) was the strongest predictor in early adolescence for substance use, while BI dominated in middle adolescence.
• Predictive power shifted from BW to BE and then to previous behavior as adolescents aged and gained experience.
• For less experienced students, BW was superior, whereas BI predicted better for those with more experience in class skipping.

Conclusions:

• The predictive validity of BI, BE, and BW is developmentally sensitive, changing with age and behavioral experience.
• Findings suggest a developmental shift from more reactive (BW) to more reasoned (BI, BE) cognitive processes in risk-taking.
• Tailoring interventions based on developmental stage and experience level is recommended for effectively targeting adolescent risk behaviors.
