Abstract:
OBJECTIVE: The purposes of this study were to clarify the roles of personality characteristics and general psychopathology, including depression and hypochondriasis, in individuals with eating disorders, and to test a continuum hypothesis of eating disorders. METHODS: Using a multi-stage questionnaire sampling method including area sampling, proportionated stratified sampling, and quota sampling, we surveyed 3,062 subjects(1249 males and 1813 females) from a target of 4,400 Korean adults over the age of 18 in a nationwide area(9 ku's, 10 middle or small cities, and 17 kun's). We used the questionnaire which consisted of three parts:general information, scales for eating traits, and scales for personality characteristics and other general psychopathology. RESULTS: Psychoticism was the only personality characteristics which had a significant relationship with various eating traits including 'eating habits'(r=-0.3195), 'the Eating Attitudes Test'(EAT, r=0.3657), and 'preference for vegetables and fish, and dislike for sweet,tasting foods'(r=-0.2740). Lie scale also had a significant relationship with 'preference for snacks and instant foods'(r=-0.2117). These results were consistent in examining the relationships across genders. In female, there was a significant relationship between 'preference for the traditional Korean foods' and 'psychoticism'(r=-0.2103) in addtion to above relationships. However, there were no significant relationships between any of the eating traits and other psychopathology. Relative to the relationship between personality characteristics and general psychopathology, there were significant correlations between 'depression' and 'interoversion-extraversion'(r=-0.2174), 'depression' and 'neuroticism'(r=0.4510>, and 'hypochondriasis' and 'neuroticism'(r=0.3432). These correlations in female was the same as those of the total group, while among males, 'depression' was significantly correlated with all four personality characteristics, and 'hypochondriasis' was significantly correlated with 'interoversion-extraversion'(r=-0.2265) and 'neuroticism'(r=0.3762). CONCLUSION: These results suggest that psychoticism is the only personaltiy characteristics related to eating-specific psychopathology, while general psychopathology, such as depression and hypochondriasis is not related to eating pathology but may influence eating disorders by their interaction with other personality characteristics, such as interoversion-extraversion and neuroticism. Considering the results of previous studies in the patients with eating disorders and high risk groups, which are similar with our results in the general population, our results support a continuum hypothesis of eating disorders. Our results also suggest that gender differences in the pathology of eating disorders are the result not of difference in eating-specific pathology itself but through difference in influences of concurrent general psychopathology, such as depression and hypochondriasis.
