The authors assessed eating behaviors and attitudes of 225 college freshman women on the bulimia and restraint scales at the beginning of the year. Seven months later, they reassessed 104 of the original students. Concurrent data regression analyses found that symptoms of eating pathology were associated with figure dissatisfaction, ineffectiveness, public self-consciousness, and vigor on the Profile of Mood States, and for bulimia, self-efficacy to control eating when experiencing negative feelings, and reward conditions. Both bulimia and restraint were highly stable across the 7 months. Prospective analyses, controlling for the initial level of eating pathology in hierarchical regressions, found that figure dissatisfaction, ineffectiveness, and alcohol use/abuse over the past year were significant predictors of worsening symptoms. Beginning levels of bulimia and restraint were the best predictors of eating pathology at the end of the study. The roles that self-image and alcohol use may play as vulnerabilities for eating pathology are also considered.
作者在年初对225名大学新生女性进行了关于暴食和节制量表的饮食行为及态度评估。七个月后,他们对其中104名最初参与研究的学生进行了重新评估。同时进行的数据回归分析发现,饮食病理学症状与身体形象不满、无效感、公众自我意识以及情绪状态量表中的活力相关,对于暴食症而言,还与在经历负面情绪时控制饮食的自我效能感以及奖励条件相关。暴食和节制在这7个月中都具有高度稳定性。前瞻性分析在分层回归中控制了饮食病理学的初始水平,发现身体形象不满、无效感以及过去一年的酒精使用/滥用是症状恶化的显著预测因素。研究结束时,暴食和节制的初始水平是饮食病理学的最佳预测指标。同时也考虑了自我形象和酒精使用可能作为饮食病理学易感性因素所起的作用。
