People with different personality types lead very different lifestyles; these personality types also affect the eating habits of an individual. Poor eating habits can lead to a myriad of health problems, including obesity and diabetes, while healthy eating habits can promote longevity. An associated problem is inaccurate reporting of eating habits by research participants and medical patients. While many studies have been conducted to examine the relationship between eating disorders and personality types, very few, if any, have examined the effects of personality types on actual eating habits as well as perceived eating habits. The proposed study will test for associations between personality traits and eating habits and inaccuracy in self-reported eating habits. Using the five factor personality model, participants will be given a questionnaire to assess the personality traits of openness, conscientiousness, extraversion, agreeableness, and neuroticism. Participants will then be given two more questionnaires to determine their actual eating habits and their perceived eating habits. The actual eating habits will be determined using the Self Reported Habit Index, a rigorous eating habit assessment that that can accurately determine the habits of an individual. Participants’ perceived eating habits will be assessed using a questionnaire designed specifically for this study that will assess their general view of the healthiness of their own eating habits. Participants will be gathered via Amazon’s Mechanical Turk. Through analysis of this data, conclusions will be drawn about the susceptibility of various personality traits to detrimental eating habits. Additionally, the discord between perceived and actual eating habits will be determined to provide insight into the attitudes of individuals regarding their own eating habits. This information will equip medical professionals and dieticians with knowledge about how to best accommodate patients with poor eating habits and provide them with top-notch treatment.
