For a nutrition program evaluation in a low-income community, which data collection method yields the largest response rate?

Surveys administered in person typically yield the largest response rates, especially in low-income communities. This method allows for direct interaction between the survey administrator and participants, which can enhance engagement and motivate individuals to respond. In-person surveys can also help clarify questions, address concerns, and provide immediate assistance, thereby reducing the likelihood of misunderstanding or reluctance to participate.

Additionally, personal interaction may build trust, making participants more comfortable sharing information, particularly in communities where there may be hesitation towards written or digital surveys due to various socioeconomic factors. Face-to-face administration allows for the collection of valuable qualitative data that can further enrich the evaluation.

While web-based surveys offer convenience and can be cost-effective, they often have lower participation rates, particularly in low-income populations where access to technology and digital literacy may be limited. Similarly, mailed surveys can face challenges such as lower response rates and issues with delivery or interest. The nominal group process is a qualitative method designed to gather diverse opinions in a group setting but may not be effective for collecting data from large numbers of individuals, which is often needed for robust evaluation.
