Abstract

Interoception (e.g., abilities to recognize/attend to internal sensations) is robustly associated with psychopathology. One form of interoception, body trust, is relevant for the development of disordered eating and suicidal thoughts/behaviors. However, measures of body trust are narrow, despite research suggesting body trust is multifaceted. The aim of this study was to develop a comprehensive measure of body trust: The Body Trust Scale (BTS). 479 U.S. adults completed self-report surveys containing the BTS and psychopathology measures. Exploratory and confirmatory factor analyses revealed a three-factor structure: Comfort with One's Body, Physical Attractiveness, and Comfort with Internal Sensations. Factors showed strong construct, convergent, and divergent validity, as well as moderate predictive validity for suicidal thoughts/non-suicidal self-injury. Furthermore, factors showed strong internal consistency, test-retest reliability, and were invariant across the gender binary. The BTS can be used in research and clinical settings to understand how specific facets of body trust relate to psychopathology.

身体信任量表的开发和心理测量验证。

内感知（如识别/关注内部感觉的能力）与精神病理学密切相关。内感知的一种形式--身体信任与饮食失调和自杀想法/行为的发展有关。然而，尽管研究表明身体信任是多方面的，但对身体信任的测量却很狭窄。本研究旨在开发一种全面的身体信任测量方法：身体信任量表（BTS）。479 名美国成年人完成了包含身体信任量表和心理病理学测量的自我报告调查。探索性和确认性因子分析显示了一个三因子结构：对自己身体的舒适感、身体吸引力和对内部感觉的舒适感。各因子显示出很强的建构效度、聚合效度和发散效度，以及对自杀想法/非自杀性自伤的适度预测效度。此外，各因子还显示出很强的内部一致性和重测可靠性，并且在性别二元对立的情况下保持不变。BTS可用于研究和临床，以了解身体信任的特定方面与精神病理学的关系。
