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.
