This study tested whether appearance comparisons to fitspiration images on Instagram are reciprocally associated with positive body image, negative body image, and dietary restraint. Adult women were invited to complete study measures at the baseline ( = 3039), 4-month ( = 1453), and 8-month ( = 1329) follow-up. Cross-lagged panel analyses were computed to test hypothesized bidirectional relationships using full information maximum likelihood to handle missing data. Results identified a unidirectional relationship between positive body image and fitspiration comparisons: higher positive body image (body appreciation) predicted lower fitspiration comparisons at each time-point. Evidence for bidirectional associations between fitspiration comparisons, negative body image and dietary restraint was also found. Higher negative body image and dietary restraint predicted greater fitspiration comparisons, and higher fitspiration comparisons predicted greater negative body image and dietary restraint. The findings identify factors associated with appearance-related fitspiration comparisons. Social media literacy programs may benefit from addressing comparisons to fitspiration content depicted on Instagram.
本研究旨在测试在 Instagram 上与健身灵感图片进行外观比较是否与积极的身体形象、消极的身体形象和饮食控制呈反向相关。成年女性被邀请在基线（ = 3039）、4 个月（ = 1453）和 8 个月（ = 1329）的随访中完成研究测量。使用完全信息极大似然法处理缺失数据，进行交叉滞后面板分析以测试假设的双向关系。结果表明，积极的身体形象和健身灵感比较之间存在单向关系：每个时间点，更高的积极身体形象（身体欣赏）预示着更低的健身灵感比较。也发现了健身灵感比较、消极身体形象和饮食控制之间存在双向关联的证据。更高的消极身体形象和饮食控制预示着更大的健身灵感比较，而更高的健身灵感比较预示着更大的消极身体形象和饮食控制。研究结果确定了与外观相关的健身灵感比较相关的因素。社交媒体素养计划可能受益于解决在 Instagram 上展示的健身灵感内容的比较问题。
