The Health Behaviour in School-aged Children (HBSC) study: methodological developments and current tensions.

Area of Science:

• Cross-national survey methodology
• Public health research
• Adolescent health

Background:

• The Health Behaviour in School-aged Children (HBSC) survey has a long history of cross-national data collection.
• Methodological development is crucial for maintaining data quality and relevance in large-scale surveys.
• Understanding past methodological choices informs future survey design.

Purpose of the Study:

• To trace the methodological evolution of the HBSC survey since its establishment.
• To identify and analyze key methodological tensions inherent in large-scale, cross-national surveys.
• To offer insights for ongoing and future survey development.

Main Methods:

• Collaborative analysis of archival data.
• Discussions and shared understanding with HBSC network members.
• Retrospective examination of survey methodology development.

Main Results:

• Four primary tensions were identified: balancing quality with rapid growth, continuous improvement with limited finances, trend analysis with questionnaire adaptation, and meeting diverse scientific/policy needs.
• These tensions are likely to persist in future survey cycles.
• The HBSC network's structure and experience are key to navigating these challenges.

Conclusions:

• The HBSC survey's long-term experience provides a potential model for other large-scale cross-national studies.
• The identified tensions require ongoing attention and strategic management.
• The HBSC network's collaborative structure aids in addressing methodological challenges.
