Salad=success and fries=failure? Conceptualizing and assessing self-control outcome measures in food decision-making research

摘要

Researchers studying decisions about food utilize a wide variety of measures to assess self-control outcomes in experimental studies. However, it is often unclear whether or not the chosen dependent variables truly implicate self-regulatory mechanisms in decision making. In the present research, we provide a conceptual framework for evaluating self-control outcome measures, concentrating specifically on the domain of food and eating self-control decisions. We propose and empirically examine the essential characteristics [i.e., (i) recognized as self-control relevant by study population, (ii) related to individual differences in self-control, and (iii) recognized as self-control relevant by individual] of good self-control outcome measures and provide specific methodological recommendations (including the rank-then-choose method) for capturing exhibited self-control in the domain of food decision making. Our conceptual developments and recommendations seek to enhance the consistency, efficiency, and effectiveness of food-related decision research. Copyright (c) 2015 John Wiley & Sons, Ltd.
