On Consistency of Self- and Proxy-reported Regular Smoking Initiation Age

Area of Science:

• Public Health
• Epidemiology
• Behavioral Science

Background:

• Early smoking onset correlates with increased tobacco use and extended smoking duration.
• Accurate estimation of early smoking behaviors is a public health priority.

Purpose of the Study:

• To evaluate the reliability of proxy reports for age of smoking initiation.
• To compare the consistency of proxy-reported versus self-reported smoking behaviors over time.

Main Methods:

• Utilized data from the 2002-2003 Tobacco Use Supplement to the Current Population Survey.
• Employed sequential multiple-testing methods to analyze consistency of self- and proxy-reports across two survey waves.
• Examined consistency across demographic subgroups (age, gender) and survey modes (phone, in-person).

Main Results:

• Self-reports demonstrated higher reliability and consistency over time compared to proxy or mixed reports.
• The highest rate of perfect agreement in reporting smoking history was observed with self-reports.
• Report consistency varied based on respondent type, subject's age, and survey administration method.

Conclusions:

• Self-reporting is the preferred method for accurately assessing age of smoking initiation.
• Findings highlight the importance of respondent type and survey methodology in smoking behavior research.
• Improved accuracy in early smoking estimates can inform targeted public health interventions.
