Endorsement of Diagnostic and Statistical Manuel of Mental Disorders-Iv Dependence Criteria in Eating Behavior
2010 - 117 pages
To test the validity of the seven Diagnostic Statistical Manual-IV (DSM-IV) dependence (formerly termed 'addiction') criteria as applied to eating behavior, I administered a paper and pencil adaptation of the criteria to 48 members of a church attending a health fair and 17 students attending an adult education class on the effects of refined carbohydrates. Participants endorsed criteria meaning they indicated true or yes to the behavior described in a criterion without the evaluation of a trained interviewer. Two adaptations were developed to test for convergent validity. the first was a minimal rewording of the DSM-IV criteria. the second was more descriptive of symptoms and was adapted from a validated instrument, the Structured Clinical Interview for the DSM (SCID). Answers to the seven criteria were weighted for the number of foods indicated as used in the behavior. the test was given twice to evaluate for test-retest reliability (n=13). BMI and physical activity data were tested for predictive validity. Principal component analysis was performed as a pilot. Cronbach's alpha for participants taking the test for the first time (excluding the population who took the test a second time) was .67 for the DSM adaptation and .81 for the SCID adaptation. Pearson's Correlation for the test-retest was .60 (p=.015) for the DSM and .51 (p=.05) for the SCID. Convergent validity was .517 (p=.00). Discriminant validity using categorical analysis was demonstrated for BMI (p
