Abstract

Objective: A two-arm cluster randomized controlled trial evaluated the impact of Body Confident Athletes (BCA) on girls' (N = 568, 11-17 years) body image, sports enjoyment, and affect.

Method: Sports organizations were randomly allocated (1:1) into either an intervention (BCA; k = 29) or waitlist control condition (k = 33). Girls and coaches in the intervention condition completed three 60-min sessions over three consecutive weeks. Primary outcomes were the immediate and short-term changes in girls' body esteem, with secondary outcomes assessing changes in girls' body appreciation, self-objectification, attuned self-care, sports enjoyment, and affect.

Results: Girls in the BCA condition reported significant small improvements in body esteem, body appreciation, attuned self-care, self-objectification, and negative affect at postintervention, with several effects either maintained (attuned self-care at 1-month follow-up [T3], but not at 3-month follow-up [T4]) or reemerging at later follow-up points (body esteem and self-objectification at T4, but not at T3). Effects were not maintained for body appreciation or negative affect, nor did effects emerge for sports enjoyment or positive affect. Coaches were effective interventionists (i.e., 80% accuracy), with most girls comprehending key intervention messages (85.1%).

Conclusion: BCA is the first coach-led positive body image intervention designed for girls in sport. The findings of the current trial show that BCA is a scalable body image intervention accurately delivered by sport community members, resulting in immediate and short-term improvements in girls' body image.

女性运动员身体形象干预的随机对照试验。

目的：通过两组随机对照试验，评价身体自信运动员（Body confidence Athletes， BCA）对女生（N = 568, 11-17岁）身体形象、运动享受和情感的影响。方法：将体育组织按1:1的比例随机分配到干预组(BCA；K = 29)或等候名单对照条件（K = 33）。干预组的女孩和教练在连续三周内完成了三次60分钟的训练。主要结果是女孩身体自尊的即时和短期变化，次要结果评估女孩身体欣赏，自我客观化，协调自我护理，运动享受和影响的变化。结果：BCA条件下的女孩在干预后的身体自尊、身体欣赏、协调自我护理、自我客观化和负面情绪方面有显着的小幅改善，其中一些效果要么保持（1个月随访[T3]时协调自我护理，但在3个月随访[T4]时没有），要么在随后的随访点再次出现（T4时身体自尊和自我客观化，但在T3时没有）。对身体欣赏或消极影响的影响没有维持，对运动享受或积极影响的影响也没有出现。教练是有效的干预者（即准确率为80%），大多数女孩理解关键的干预信息（85.1%）。结论：BCA是第一个以教练为主导的女生体育运动积极身体形象干预。目前的试验结果表明，BCA是一种可扩展的身体形象干预，由体育社区成员准确提供，导致女孩身体形象的即时和短期改善。（PsycInfo Database Record (c) 2025 APA，版权所有）。
