We examined young women's opinions of five common eating disorder (ED) prevention themes in terms of persuasiveness and impact on behavioral intentions. Video-taped prevention themes were rated by female adolescents and young adults (ages 13-25) with and without eating disorders. Overall, younger participants found the prevention messages less persuasive than older participants. Controlling for age, clinical participants found the messages to be less persuasive than did non-clinical participants. Clinical participants reported no change in their behavioral intentions after watching the videos, whereas non-clinical participants reported a lower intention to diet and make body comparisons after viewing the messages. Presenter ratings (attractiveness, credibility, thinness) also positively predicted individuals' opinions of the messages. The findings suggest that younger adolescents and women who already display signs of disordered eating may be hard to persuade through ED prevention messages, and further research is needed to improve their impact among these groups.
我们从说服力以及对行为意图的影响方面，研究了年轻女性对五个常见饮食失调（ED）预防主题的看法。有或没有饮食失调问题的女性青少年和年轻成年人（年龄在13 - 25岁之间）对预防主题的录像进行了评分。总体而言，较年轻的参与者认为预防信息的说服力不如年长的参与者。在控制年龄因素后，临床参与者认为这些信息的说服力不如非临床参与者。临床参与者报告称观看视频后他们的行为意图没有变化，而非临床参与者报告称在观看这些信息后节食和进行身体比较的意图降低了。呈现者评分（吸引力、可信度、瘦度）也正向预测了个体对这些信息的看法。研究结果表明，年龄较小的青少年以及已经表现出饮食失调迹象的女性可能很难被饮食失调预防信息说服，需要进一步开展研究以提高这些信息在这些群体中的影响力。
