Although historically conceptualized as problems of youth, recent research indicates that women of all ages experience body dissatisfaction and eating disorder (ED) pathology. Despite this, existing body image interventions predominantly target youth. The Body Project (BP) has extensive support for reducing ED risk factors in younger women and girls. The current proof-of-concept study investigated the feasibility, acceptability, and estimates of intervention effect sizes of a modified BP for adult women, the Women’s Body Initiative (WBI). Conducted in the Southwestern United States, adult women (N = 13) aged 29–70 (M = 49.1) participated in 4, 1-h weekly sessions, completing measures at baseline, post-intervention, and 3-month follow-up. Participants rated the program as highly feasible and acceptable. Within-subjects effects sizes were medium to large for primary outcomes (body dissatisfaction, ED pathology) and secondary outcomes (psychosocial impairment, negative affect, quality of life, nutritious food consumption, and sleep) through 3-months. Results suggest preliminary feasibility and acceptability of WBI for adult women, and support proceeding with a larger trial to investigate intervention efficacy.

尽管历史上被概念化为青年问题，但最近的研究表明，所有年龄段的女性都会经历身体不满和饮食失调 (ED) 病理。尽管如此，现有的身体形象干预主要针对年轻人。Body Project ( BP ) 广泛支持减少年轻女性和女孩的 ED 风险因素。目前的概念验证研究调查了女性身体倡议( WBI )对成年女性改良BP干预效果大小的可行性、可接受性和估计。在美国西南部进行，成年女性 ( N  = 13) 年龄在 29-70 ( M = 49.1) 参加 4 次每周 1 小时的会议，在基线、干预后和 3 个月的随访中完成测量。参与者认为该计划是高度可行和可接受的。在 3 个月内，主要结果（身体不满意、ED 病理学）和次要结果（心理社会障碍、负面影响、生活质量、营养食品消耗和睡眠）的受试者内效应大小为中到大。结果表明WBI对成年女性的初步可行性和可接受性，并支持进行更大的试验以调查干预效果。
