Abstract

Given that mobile digital imaging analyses (DIA) are equipped to automate body composition and subsequently alter one’s appearance at a given objective body fat percent (BF%), the purpose of this study was to validate the use of this tool for assessments of body image. Participants (f = 134, m = 89) from two separate centers underwent body composition scans using a mobile DIA and completed the Multidimensional Body Self-Relations Questionnaire–Appearance Scale (MBSRQ-AS). Using a DIA-generated avatar, participants altered their figure so that it represented their perceived body, ideal body, and what a partner would find attractive. Distortion was calculated as perceived minus actual BF% and dissatisfaction was calculated as either ideal or partner minus perceived BF%. The total sample and females (p < 0.050), but not males, had significantly lower perceived BF% compared to their actual. Ideal and partner BF% was significantly lower than the perceived BF% for all groups (all p < 0.050). Ideal and partner BF% mean differences (MD) from perceived were positively associated with appearance evaluation (AE) and body area satisfaction (BAS) and negatively associated with overweight preoccupation and self-classified weight for the total sample (all p < 0.050). Perceived_MD demonstrated negative associations with AE and BAS (p < 0.050), but only for females when separated by sex. Perceptual body image measured by DIA is significantly associated with attitudinal body image and may allow practitioners to better quantify this growing issue.

利用移动数字成像分析验证新型感知身体形象评估方法：在多种族样本中进行的跨部门多中心评估

鉴于移动数字成像分析仪（DIA）能够自动生成身体成分，并在给定的客观体脂率（BF%）下改变人的外观，本研究旨在验证该工具在身体形象评估中的应用。来自两个不同中心的参与者（女=134，男=89）使用移动 DIA 进行了身体成分扫描，并完成了多维身体自我关系问卷-外貌量表（MBSRQ-AS）。通过使用 DIA 生成的头像，参与者改变了自己的身材，使其代表自己的感知身材、理想身材以及伴侣认为有吸引力的身材。失真度的计算方法是感知BF%减去实际BF%，不满意度的计算方法是理想BF%或伴侣BF%减去感知BF%。总样本和女性（p <0.050）的感知 BF% 明显低于实际 BF%，而男性则不然。所有群体的理想和伴侣 BF% 都明显低于感知 BF% （所有 p 均为 0.050）。在所有样本中，理想和伴侣 BF% 与感知 BF% 的平均差（MD）与外貌评价（AE）和身体部位满意度（BAS）呈正相关，而与超重预想和自我体重分类呈负相关（所有 p < 0.050）。知觉身体形象（PerceivedMD）与AE和BAS呈负相关（p <0.050），但按性别区分时，仅女性与之呈负相关。通过DIA测量的知觉体型形象与态度体型形象有显著关联，可使从业人员更好地量化这一日益严重的问题。

期刊介绍： Behavior Therapy is a quarterly international journal devoted to the application of the behavioral and cognitive sciences to the conceptualization, assessment, and treatment of psychopathology and related clinical problems. It is intended for mental health professionals and students from all related disciplines who wish to remain current in these areas and provides a vehicle for scientist-practitioners and clinical scientists to report the results of their original empirical research. Although the major emphasis is placed upon empirical research, methodological and theoretical papers as well as evaluative reviews of the literature will also be published. Controlled single-case designs and clinical replication series are welcome.
