This study compared the effectiveness of two approaches to imagery rescripting (body versus general) among young women with an elevated risk of developing an eating disorder.
University students (N = 130 females) were randomly assigned to one of the four conditions: body or general imagery rescripting, psychoeducation, control. After initial brief laboratory training delivered online, participants in the imagery rescripting conditions were asked to practice imagery rescripting for 5 min each day for a week. Primary (global eating psychopathology, eating disorder behaviors, and body image acceptance) and secondary outcomes (self-compassion, fear of self-compassion, and dysfunctional attitudes) were measured at baseline and one-week follow up.
Completer analyses showed both imagery rescripting conditions and psychoeducation had significant impact on global eating psychopathology and body acceptance (d = 0.60-0.78). Psychoeducation did not impact secondary variables, whereas body imagery rescripting improved self-compassion and fear of self-compassion (d = 0.61-0.80) and general imagery rescripting improved dysfunctional attitudes (d = 0.82) compared to control. Intent to treat analyses had similar but slightly less robust results.
While three active groups had significant impact on the primary variables, imagery rescripting approaches had impact on other variables that maintain disordered eating. Future research should investigate the impact of combining psychoeducation and imagery rescripting in terms of impact on disordered eating.
本研究比较了两种意象重写方法(身体意象重写和一般意象重写)对有发展进食障碍风险的年轻女性的效果。
将大学生(N=130 名女性)随机分配到以下四个条件之一:身体意象重写或一般意象重写、心理教育、对照组。在线进行初步短暂的实验室训练后,意象重写组的参与者被要求每天进行 5 分钟的意象重写,持续一周。在基线和一周随访时测量主要(整体进食心理病理学、进食障碍行为和身体意象接受)和次要结果(自我同情、对自我同情的恐惧和功能失调态度)。
完成分析显示,两种意象重写条件和心理教育都对整体进食心理病理学和身体接受有显著影响(d=0.60-0.78)。心理教育对次要变量没有影响,而身体意象重写改善了自我同情和对自我同情的恐惧(d=0.61-0.80),一般意象重写改善了功能失调态度(d=0.82),与对照组相比。意向治疗分析有类似但略不那么有力的结果。
虽然三个活跃组对主要变量有显著影响,但意象重写方法对维持饮食障碍的其他变量也有影响。未来的研究应该调查心理教育和意象重写相结合在饮食障碍影响方面的效果。
