This study compared the effect of imagery rescripting focusing on self-compassion, imagery rescripting focusing on mastery, and a positive memory control condition on (1) emotional responses towards the memory (one day after), (2) changes in the believability of negative core beliefs, and dysfunctional eating behaviors (one week after) in individual at risk for developing an eating disorder.
Female participants (N = 69) were allocated to one of three conditions: ImRs focusing on self-compassion (N = 24), ImRs focusing on self-mastery (N = 23), and positive memory control condition (N = 22). Participants in the ImRs conditions received a 20-min self-guided ImRs intervention, whereas participants in the control condition received a 20-min self-guided task focusing on an unrelated positive memory.
The experimental manipulation successfully induced the use of self-compassion and mastery strategies in the respective imagery rescripting condition. However, our data show that a single 20-min session of self-guided imagery rescripting focusing on compassion and/or mastery has no effect on the emotional response towards the aversive memory or in the change of core beliefs and eating behaviors at follow up.
We discuss potential reasons for the null findings, including the use of a single imagery rescripting session, the sample size and the measurement of manipulation checks.
Future studies are needed to rule out methodological explanations for the null results. These findings may be of value for the development of future experimental lab paradigms which aim to evaluate the causal effects and working mechanisms of imagery rescripting.
本研究比较了意象重写聚焦自我同情、意象重写聚焦掌控、以及积极记忆控制条件对(1)对记忆的情绪反应(一天后)、(2)对消极核心信念的可信度的变化,以及对有饮食障碍风险的个体的不良进食行为(一周后)的影响。
将女性参与者(N=69)分配到三个条件之一:自我同情焦点的 ImRs(n=24)、自我掌控焦点的 ImRs(n=23)和积极记忆控制条件(n=22)。ImRs 条件的参与者接受了 20 分钟的自我指导的 ImRs 干预,而控制条件的参与者则接受了 20 分钟的自我指导任务,重点关注无关的积极记忆。
实验操作成功地在各自的意象重写条件中诱导了自我同情和掌控策略的使用。然而,我们的数据表明,单次 20 分钟的自我指导意象重写聚焦于同情和/或掌控,对不良记忆的情绪反应或核心信念和进食行为的变化没有影响。
我们讨论了无效结果的潜在原因,包括单次意象重写会话的使用、样本量和操作检查的测量。
需要进一步的研究来排除无效结果的方法学解释。这些发现可能对未来实验实验室范式的发展有价值,这些范式旨在评估意象重写的因果效应和工作机制。
