Objective: The present study was designed to compare response rates on a standard self-report questionnaire that was nominally anonymous to an unmatched count questionnaire that allowed for true anonymity in responding. Method: Four hundred and fifty-four college students were asked about several topics, including attitudes towards weight and shape, dieting, and eating disordered behavior using one of two response formats; either a standard questionnaire in true-false format or an unmatched count questionnaire that did not require participants to directly answer sensitive questions. Results: Both males and females had significantly different rates of endorsement between the two methods of assessment on the majority of the eating-related questions. Conclusion: Response format and degree of anonymity affect endorsement of eating-related thoughts and behaviors. Understanding response bias is critical to determining accurate rates of eating disordered thoughts and behaviors.
