Understanding How Consumers Cope with Food Safety Concerns: Using Qualitative Panel Data to Obtain a Complete Picture

Abstract:

American consumers are increasingly concerned about the microbial safety of the fruits and vegetables they consume.  A random survey of 3,619 consumers from the Gallup Panel performed in October 2008 investigated the extent to which American consumers were concerned about the microbial safety of produce and how they coped with those concerns in the food marketing channel.

Do One-Time Inducements Help Long-Term Survey Participation? – A Case for Survival Analysis

Abstract:

In a recent study involving a mixed-mode experiment to recruit members to a consumer panel, Rao et al. (2010) tested the effect of various response-inducement techniques such as advance letters, monetary incentives, and telephone follow-up on panel recruitment. The experiment was successful in recruiting individuals to a non-incentive-driven consumer panel (i.e., members do not receive any form of monetary incentives for their participation in the panel). While the experiment used response inducements as a onetime stimulus to motivate individuals to join the panel, no such response inducements were provided for their subsequent panel participation.

A Comparison of Web and Mail Survey Respondents within a Mixed Mode National Survey

Abstract:

Web surveys are being increasingly incorporated into national survey data collection programs in the United States because of their cost/time-efficiencies. Yet, response rates and data quality issues in web surveys remain important challenges. As a basic study designed to better understand data quality, this paper investigates the degree to which survey modes themselves affect response rates and data quality in a national mixed mode survey.

The Theory and Evaluation of Anchoring Effect in Visually Administered Extremely Long Response Lists

Abstract:

Numerous studies (Payne 1971; Krosnick and Alwin 1987; Ayidiya and McClendon 1990; Schwarz, Hippler, and Noelle-Neumann 1992; Malhotra 2009; Malhotra 2008) have examined response order effects in visually administered questionnaires. A number of theories have also been proposed to explain this effect, with the most popular one being the theory of satisficing (Krosnick and Alwin 1987; Krosnick 1991). According to this theory, when response alternatives are presented visually, respondents begin at the top of the list and consider each alternative individually, all while establishing a cognitive framework for evaluating later response alternatives.
