Cross‐Cultural Adaptation and Psychometric Validation of the Body Perception Questionnaire‐Short Form (BPQ‐SF) Among Chinese Patients With Coronary Heart Disease

Objective To revise the Brief Body Perception Questionnaire (BPQ‐SF) for applicability in patients with coronary heart disease (CHD), and to examine its reliability and psychometric characteristics. Methods In Sample 1 ( n = 371), items from the two subscales of the BPQ‐SF were revised using expert consultation and item analysis, followed by exploratory factor analysis (EFA). Sample 2 ( n = 350) was used for confirmatory factor analysis (CFA) and for evaluating structural validity, internal consistency, test–retest reliability, and criterion‐related validity. Results The revised BPQ‐SF consists of 30 items across two subscales: Body Awareness (15 items) and Autonomic Reactivity (15 items). The scale demonstrated good structural validity, internal consistency, and test–retest reliability. The total score was significantly and positively correlated with anxiety as measured by the Hospital Anxiety and Depression Scale‐Anxiety subscale (HADS‐A) ( r = 0.368, p < 0.01). Conclusion The revised BPQ‐SF shows sound reliability and validity in hospitalized patients with CHD and serves as a reliable tool for assessing interoceptive sensitivity and emotional states. It offers a valuable measurement basis for the early detection and intervention of anxiety in patients with coronary heart disease.
