This preliminary randomized controlled trial assessed the feasibility of a pilot mindfulness-based intervention with respect to reducing the risk of eating disorders in young women.
Forty-four young adult women with body image concerns (Mage = 20.57, SD = 3.22) were randomly allocated to a mindfulness-based or a dissonance-based intervention (3 × 1 h weekly sessions), or to assessment-only control. Self-report measures of eating disorder risk factors, symptoms and related psychosocial impairment were compared at baseline, post-intervention, and at 1- and 6-month follow up.
At post-intervention, acceptability ratings for both interventions were high. Mindfulness participants demonstrated statistically significant improvements relative to control at post-intervention for weight and shape concern, dietary restraint, thin ideal internalization, eating disorder symptoms and related psychosocial impairment; however, these gains were largely lost over follow up. Dissonance participants did not show statistically significant improvements relative to control on any outcomes, despite small to moderate effect sizes.
These preliminary findings demonstrate the acceptability and short-term efficacy of a mindfulness-based approach to reducing the risk of disordered eating in young women. This provides support for the continued evaluation of mindfulness in the prevention and early intervention of eating disorders, with increased efforts to produce maintenance of intervention gains.
这项初步随机对照试验评估了一项基于正念的干预措施在降低年轻女性饮食失调风险方面的可行性。
44名关注身体形象的年轻成年女性(年龄中位数=20.57,标准差=3.22)被随机分配到基于正念的干预组、基于认知失调的干预组(每周3次,每次1小时)或仅进行评估的对照组。在基线、干预后、1个月和6个月随访时,比较饮食失调风险因素、症状及相关心理社会功能损害的自我报告测量结果。
干预后,两种干预措施的可接受性评分都很高。正念干预组在干预后相对于对照组,在体重和体型关注、饮食限制、瘦理想内化、饮食失调症状及相关心理社会功能损害方面有统计学显著改善;然而,这些改善在随访过程中大多消失。认知失调干预组在任何结果上相对于对照组均未显示出统计学显著改善,尽管效应大小为小到中度。
这些初步研究结果证明了基于正念的方法在降低年轻女性饮食失调风险方面的可接受性和短期疗效。这为继续评估正念在饮食失调预防和早期干预中的作用提供了支持,同时加大努力以维持干预效果。
