Which practice contributes to data quality assurance in behavior-change research?

• A. Standardized Data Collection
• B. All of the Above
• C. Data Validation
• D. Training

Answer: (B)

In behavior-change research, ensuring data quality comes from a combination of reliable measurement, careful checking, and well-prepared staff. Standardized data collection ensures everyone follows the same procedures and uses the same instruments, which reduces variation due to how data are gathered. Data validation matches what was collected against rules for accuracy and completeness, catching mistakes, outliers, or inconsistencies that could distort findings. Training equips researchers and field staff with the proper protocols and the importance of precise data, which improves consistency, reduces mistakes, and enhances reliability across raters and sites. When you put these elements together, you create a comprehensive approach to maintain high-quality data from collection through entry and analysis. All of these practices contribute to data quality assurance, so they collectively represent the best choice.
