目的：对中文版身体意象灵活及不灵活量表进行修订,并在中国大学生群体中对其信度和效度进行检验。
方法：2023年11月—12月,采用方便取样法对内蒙古自治区和四川省3所高校的1 062名本科生施测。首先,对30名大学生进行中文版身体意象灵活及不灵活初始量表的通俗度检验,形成正式量表。接着,采用正式量表对480名大学生施测,并对数据进行项目分析与探索性因素分析。此后,再次使用正式量表对482名大学生进行测量,并对数据进行验证性因素分析、信度与效度分析。为检验量表的稳定性,2周后对上述被试中的70名大学生进行重测。
结果：探索性因素分析发现,中文版身体意象灵活分量表包括正念接受和积极情感认知2个维度,共12个项目;中文版身体意象不灵活分量表包括主动回避、消极情感认知2个维度,共11个项目。验证性因素分析发现,该量表模型拟合效果良好（灵活分量表：χ2/df=2.663,NFI=0.909,TLI=0.926,CFI=0.940,IFI=0.941,RMSEA=0.059;不灵活分量表：χ2/df=3.437,NFI=0.930,TLI=0.934,CFI=0.949,IFI=0.949,RMSEA=0.071）。身体意象灵活得分与身体知觉得分呈负相关（r=-0.071,p<0.05）,与身体欣赏得分呈正相关（r=0.464,p<0.01）;身体意象不灵活得分与身体欣赏得分呈负相关（r=-0.073,p<0.05）,与身体知觉得分成正相关（r=0.334,p<0.01）,具有较好的校标关联效度。信度检验发现,2个分量表的Cronbach’s α系数分别为0.843、0.874。
结论：中文版身体意象灵活及不灵活量表的信度与效度指标均与原量表信度与效度保持较高一致性,均符合心理测量学指标,可以作为评估中国大学生身体意象灵活性测量工具。
Objective: To revise the Chinese version of the Body Image Flexibility and Inflexibility Scale and examine its reliability and validity among Chinese college students.
Methods: From November to December 2023, convenience sampling was employed to survey 1 062 undergraduate students from three universities in Inner Mongolia Autonomous Region and Sichuan Province. Firstly, 30 students participated in a comprehensibility test on the initial Chinese version of the Body Image Flexibility and Inflexibility Scale to form the formal scale. Subsequently, the formal scale was used to measure 480 college students, and the data were subjected to item analysis and exploratory factor analysis. In the end, the formal scale was used to measure 482 college students, and confirmatory factor analysis and reliability and validity tests were conducted on the data. Two weeks later, 70 college students were asked to re-test for assessing test-retest reliability.
Results: Exploratory factor analysis revealed two dimensions in the Chinese version of the Body Image Flexibility Subscale: mindful acceptance and positive affective cognition, encompassing 12 items in total; and two dimensions in the Chinese version of the Body Image Inflexibility Subscale: active avoidance and negative affective cognition, with 11 items in total. Confirmatory factor analysis indicated that the models of the Chinese version of the Body Image Flexibility Subscale and Body Image Inflexibility Subscale both demonstrated good fitness (χ2/df=2.663, NFI=0.909, TLI=0.926, CFI=0.940, IFI=0.941, RMSEA=0.059; χ2/df=3.437, NFI=0.930, TLI=0.934, CFI=0.949, IFI=0.949, RMSEA=0.071). The Flexibility Subscale was negatively correlated with body perception (r=-0.07, p<0.05) and positively correlated with body appreciation (r=0.46, p<0.01); The Inflexibility Subscale was negatively correlated with body appreciation (r=-0.07, p<0.05) and positively correlated with body perception (r=0.33, p<0.01), indicating good discriminant validity. Furthermore, reliability tests showed that the overall Cronbach’s α coefficients of the two subscales were 0.843 and 0.874, respectively, indicating good internal consistency.
Conclusion: The Chinese version of Body Image Flexibility and Inflexibility Scale has good validity and reliability among Chinese college students, with each subscale having two dimensions, making it a reliable scientific research tool.
