Most of the major instruments in the eating disorder field have documented psychometric support only in predominantly White samples. The current study examined the internal consistency, temporal stability, and convergent and discriminant validity of a variety of eating disorder measures in Black (n = 97) and White (n = 179) female undergraduates. Internal consistency coefficients were good (>.76) for all measures for both groups. Temporal stability across 5 months was also adequate in both groups, but with evidence for dietary restraint and subjective binge eating being less stable in Black women (e.g., for the Restraint subscale of the Three-Factor Eating Questionnaire [TFEQ], r = .63 for Black women and r = .82 for White women). Scores on the bulimic symptoms and dietary restraint instruments converged and diverged in a theoretically consistent pattern. Findings suggest these eating disorder measures are reliable (internally consistent; temporally stable over 5 months) and that the bulimic symptom measures of the Bulimia Test-Revised, the Bulimia subscale of the Eating Disorder Inventory, and the dietary restraint measures from the Eating Disorder Examination-Questionnaire and TFEQ demonstrate convergent and discriminant validity in Black college women.
饮食失调领域的大多数主要测评工具仅在以白人为主的样本中得到了心理测量学支持的记录。本研究考察了多种饮食失调测评工具在97名黑人女大学生和179名白人女大学生中的内部一致性、时间稳定性以及聚合效度和区分效度。两组所有测评工具的内部一致性系数都良好（>.76）。两组在5个月内的时间稳定性也足够，但有证据表明，饮食节制和主观暴饮暴食在黑人女性中稳定性较差（例如，在三因素饮食问卷[TFEQ]的节制分量表中，黑人女性的r = 0.63，白人女性的r = 0.82）。暴食症状和饮食节制测评工具的得分以理论上一致的模式聚合和离散。研究结果表明，这些饮食失调测评工具是可靠的（内部一致；在5个月内时间稳定），并且修订版暴食测试的暴食症状测评工具、饮食失调量表的暴食分量表以及饮食失调检查问卷和TFEQ的饮食节制测评工具在黑人女大学生中显示出聚合效度和区分效度。
