Dental flossing and automaticity: a longitudinal moderated mediation analysis.

Area of Science:

• Behavioral psychology
• Oral health research
• Health behavior science

Background:

• Understanding predictors of oral hygiene behaviors is crucial for public health.
• Self-regulatory and automatic components of health behavior require further elucidation.

Purpose of the Study:

• To investigate the predictive roles of normative support, behavioral automaticity, and action control in dental flossing.
• To examine the mediating role of automaticity in the relationship between normative support and flossing behavior.
• To explore the moderating effect of action control on the automaticity-flossing behavior link.

Main Methods:

• A longitudinal study involving 629 Australian young adults (aged 18-25) was conducted.
• Participants completed questionnaires assessing normative support and automaticity.
• Dental flossing behavior and action control were assessed via a 2-week follow-up, with 241 participants included in the final analysis.

Main Results:

• Findings supported the hypothesis that normative support influences flossing behavior through automaticity.
• The study confirmed that action control moderates the effect of automaticity on dental flossing behavior.
• Results highlight the interplay between self-regulatory factors and automatic processes in maintaining oral hygiene.

Conclusions:

• Normative support and behavioral automaticity are key predictors of dental flossing.
• Action control plays a significant role in modulating the automaticity of flossing behavior.
• These findings offer insights into mechanisms underlying oral hygiene practices and inform interventions for behavior change.
