Abstract
Objectives
Mindfulness has been proposed as a potential intervention for eating disorders (EDs). However, a better understanding of the relationships between state mindfulness and restrictive ED symptoms for those with anorexia nervosa and atypical anorexia nervosa (AN-spectrum) is needed to design effective mindfulness-based interventions. Additionally, individualized longitudinal modeling of state mindfulness and ED behaviors could inform development of personalized mindfulness-based interventions for those with AN-spectrum disorders.
Methods
Participants (n = 18; 784 data points per participant; 14,112 data points) with AN-spectrum disorders completed four daily ecological momentary assessments of ED behaviors, nonjudgment, acceptance, and present-moment awareness for 14 days. Contemporaneous and temporal group-level and idiographic (i.e., one-person, individual) networks were calculated to identify associations among mindfulness variables and ED behaviors.
Results
In contemporaneous networks (i.e., within a single timepoint), present-moment awareness was negatively associated with eating small meals but positively associated with avoiding foods due to anxiety. Acceptance was positively associated with eating small meals. In temporal networks, nonjudgment was negatively associated with following eating rules and avoiding foods due to anxiety, whereas acceptance negatively predicted restriction prospectively. Idiographic networks were heterogenous; state mindfulness facets demonstrated positive and negative associations with ED behaviors depending on the individual.
Conclusions
At the group level, state mindfulness tends to relate to lower engagement in restrictive ED behaviors over time. High heterogeneity in individual networks illustrates the need for personalized assessment of relationships between state mindfulness and ED behaviors. These types of methodologies can lead to the development of personalized mindfulness-based interventions for those with AN-spectrum disorders.
研究目的：正念被认为是治疗进食障碍（ED）的一种潜在干预方法。然而，我们需要更好地了解神经性厌食症和非典型神经性厌食症（AN-spectrum）患者的正念状态与限制性进食障碍症状之间的关系，以设计有效的正念干预措施。方法患有神经性厌食症的参与者（n = 18；每位参与者 784 个数据点；14,112 个数据点）在 14 天内完成了对 ED 行为、非评判、接受和当下意识的四项每日生态瞬间评估。结果在当时的网络中（即在单个时间点内），当下意识与少食多餐呈负相关，但与因焦虑而避免进食呈正相关。接受与吃少食正相关。在时间网络中，不做判断与遵守饮食规则和避免因焦虑而进食呈负相关，而接受对限制进食呈负相关。在群体层面上，随着时间的推移，正念状态往往与较低的限制性 ED 行为相关。个体网络的高度异质性说明，需要对状态正念与 ED 行为之间的关系进行个性化评估。这些类型的方法可以为患有自闭症谱系障碍的人开发基于正念的个性化干预措施。
期刊介绍：
Mindfulness seeks to advance research, clinical practice, and theory on mindfulness. It is interested in manuscripts from diverse viewpoints, including psychology, psychiatry, medicine, neurobiology, psychoneuroendocrinology, cognitive, behavioral, cultural, philosophy, spirituality, and wisdom traditions. Mindfulness encourages research submissions on the reliability and validity of assessment of mindfulness; clinical uses of mindfulness in psychological distress, psychiatric disorders, and medical conditions; alleviation of personal and societal suffering; the nature and foundations of mindfulness; mechanisms of action; and the use of mindfulness across cultures. The Journal also seeks to promote the use of mindfulness by publishing scholarly papers on the training of clinicians, institutional staff, teachers, parents, and industry personnel in mindful provision of services. Examples of topics include: Mindfulness-based psycho-educational interventions for children with learning, emotional, and behavioral disorders Treating depression and clinical symptoms in patients with chronic heart failure Yoga and mindfulness Cognitive-behavioral mindfulness group therapy interventions Mindfulnessness and emotional regulation difficulties in children Loving-kindness meditation to increase social connectedness Training for parents and children with ADHD Recovery from substance abuse Changing parents’ mindfulness Child management skills Treating childhood anxiety and depression
