Cross-cultural research: trying to do it better. 1. Issues in study design

Area of Science:

• Public Health Research
• Cross-Cultural Studies
• Methodology

Background:

• Cross-cultural public health studies face unique methodological and practical challenges.
• Immigrant populations, particularly non-English speaking background groups, present specific difficulties in research.
• The Mothers in a New Country (MINC) study aimed to explore these challenges in a real-world setting.

Purpose of the Study:

• To discuss strategies for overcoming methodological and practical hurdles in cross-cultural public health research.
• To share lessons learned from the Mothers in a New Country (MINC) study regarding participant recruitment and interviewer training.
• To inform future research design for studies involving diverse cultural groups.

Main Methods:

• The study employed an interview-based approach with 318 recent mothers from Vietnamese, Turkish, and Filipino backgrounds in Melbourne.
• Systematic sampling and recruitment strategies were utilized.
• Careful selection, training, and ongoing support were provided to bicultural interviewers.

Main Results:

• A systematic approach to sampling and recruitment, alongside a flexible study protocol, achieved adequate sample size and representativeness.
• Significant attention to interviewer selection, training, and support enhanced study completion and confidence in findings.
• The study demonstrated the feasibility of conducting rigorous cross-cultural research with appropriate planning.

Conclusions:

• Researchers and funders must acknowledge the significant implications of methodological and practical issues in cross-cultural studies.
• Addressing these challenges requires careful consideration of study costs and timelines.
• Despite the complexities, successful cross-cultural research yields substantial benefits for public health understanding and interventions.
