Data from: "ABC" - the Awareness-Body-Chart: a New Tool Assessing Body Awareness

Background: Despite the importance of body awareness for health and well-being there is still a lack of valid assessment tools to scan proper body awareness. To respond to the limitations of questionnaires (reading/interpretation problems of subjects) the Awareness-Body-Chart (ABC) was designed to assess body awareness by colouring 51 regions according to their awareness. The objective of this study was to investigate the psychometric characteristics of the ABC. Methods: In a questionnaire-study, 106 students in Graz (79 females, 27 males, age median 21 (IQR 20 - 23) years) filled in the ABC, furthermore a German body awareness questionnaire „KEKS", and the Beck Depression Inventory II. Factor structure, internal consistency, and retest reliability of the ABC were investigated. Correlations of the ABC with the KEKS and the Beck Depression Inventory II and comparisons of subgroups were conducted. Results: Through factor analyses, 14 factors with clear assignments to body parts could be categorized: cranium, face, cervical/lumbar region, chest/abdomen, back, shoulder, upper arm, lower arm/elbow, hand, genital area, thigh/hip, knee, lower leg, and foot. The 14 body parts and the total score showed acceptable to high Cronbach's alphas (α = .64 - .97). The test-retest reliability showed values between ρ = .71 and ρ = .96. The correlation of the ABC and KEKS (r = .66, p < .001) confirmed validity. Further indications of validity could be seen in comparisons of subgroups and in correlations with the Beck Depression Inventory II. Conclusion: The ABC proved good psychometric properties with acceptable to high internal consistency, acceptable to high retest reliability and high construct validity. It is an easy-to-use tool for clinical settings and research. The ABC opens new insights into body awareness-patterns of various subgroups.背景：尽管躯体觉知（body awareness）对于健康与福祉至关重要，但目前仍缺乏有效的评估工具以全面评估躯体觉知水平。针对问卷法存在的被试阅读困难与理解偏差等局限，研究人员开发了躯体觉知图表（Awareness-Body-Chart, ABC），通过让被试依据自身对各身体区域的觉知程度为51个区域着色，以此评估躯体觉知。本研究旨在探究该ABC的心理测量学特征。 方法：本研究采用问卷调研范式，招募了格拉茨的106名大学生（其中女性79名，男性27名，年龄中位数为21岁，四分位距20~23岁），要求其填写ABC量表、德国版躯体觉知问卷「KEKS」以及贝克抑郁量表第二版（Beck Depression Inventory II）。研究对ABC的因子结构、内部一致性及重测信度（test-retest reliability）进行了考察，并分析了ABC与KEKS、贝克抑郁量表第二版的相关性，同时开展了亚组间比较。 结果：经因子分析，可将条目归类为14个具有明确身体部位指向的因子：颅骨、面部、颈/腰区、胸/腹部、背部、肩部、上臂、前臂/肘部、手部、生殖器区域、大腿/髋部、膝部、小腿及足部。该14个身体部位维度与总分的克朗巴哈α系数（Cronbach's alpha）介于0.64~0.97，处于可接受至较高水平。重测信度系数ρ介于0.71~0.96之间。ABC与KEKS的相关性（r=0.66, p<0.001）验证了其效标效度。亚组比较及与贝克抑郁量表第二版的相关性结果，亦为效度验证提供了进一步支撑。 结论：ABC展现出优异的心理测量学性能：内部一致性处于可接受至较高水平，重测信度符合要求，且结构效度极佳。该工具操作简便，可适用于临床场景与科研工作。此外，ABC可为探索不同亚组的躯体觉知模式提供全新视角。
