This study examined the schema-level cognitive content and processes that might explain the presence of compulsive behaviours among patients with eating disorders.
Each of 62 eating-disordered women completed standardised measures of schema-level core beliefs and cognitive processes, and was interviewed for diagnosis and obsessive compulsive features.
Compulsive behaviours were associated with four core beliefs--'mistrust/abuse', 'defectiveness/shame', 'dependence/incompetence' and 'subjugation'. Higher levels of avoidance of emotional arousal were also associated with compulsivity.
Schema-level beliefs and processes are associated with the presence of compulsivity. The key cognitions might impact via the activation of negative affect, meaning that the compulsive behaviours serve the function of emotion regulation. Such cognitions are likely to be a necessary target in CBT for those presenting with compulsive behaviours in the eating disorders.
本研究考察了可能解释饮食失调患者强迫行为存在的图式水平认知内容和过程。
62名饮食失调女性每人完成了图式水平核心信念和认知过程的标准化测量，并接受了诊断和强迫特征访谈。
强迫行为与四个核心信念相关——“不信任/虐待”、“缺陷/羞耻”、“依赖/无能”和“征服”。更高水平的对情绪唤起的回避也与强迫性相关。
图式水平的信念和过程与强迫性的存在相关。关键认知可能通过激活负面情绪产生影响，这意味着强迫行为起到了情绪调节的作用。对于饮食失调中出现强迫行为的患者，此类认知很可能是认知行为疗法中的一个必要治疗靶点。
