Developing, Piloting, and Factor Analysis of a Brief Survey Tool for Evaluating Food and Composting Behaviors: The Short Composting Survey

By Jennie Norton, Becky Pearson, David Gee and Nicole Stendell-Hollis

Abstract: Household composting is a practical sustainable behavior which should be further investigated. The Short Composting Survey was developed for use during the Compost Project pilot study to measure the knowledge, values, barriers, and social norms surrounding composting (n=25). The purpose of this research was to describe the testing and refining of the survey tool for the pilot study. Statistical analyses included calculating the Index of Item-Objective Congruence (IIOC) values and conducting a confirmatory factor analysis following administration of the survey. Nine respondents assisted with survey tool development by completing the IIOC, and values ranged from 0.29 to 0.66 which indicated that all of the survey questions matched more than one construct. The factor analysis resulted in a three-factor solution with a cumulative loading of 71.2%, meaning that these identified factors contributed 71.2% of the variance in responses. Factor 1 (“Values”) proved to be the strongest factor, explaining 36.6% of the variance, whereas Factor 2 (“Social Norms”) explained 20.04%, and Factor 3 (“Barriers”) had 14.6%. This survey may be useful for future food composting and sustainability-related research efforts.
