Key result
The HBP SCP scale (AUC 0.838) demonstrated significantly better diagnostic accuracy than the SC-HI scale (AUC 0.754) for assessing self-care ability in older Chinese adults with hypertension.
Why the study?
The study was conducted to test and compare the Self-Care of Hypertension Inventory and the Hypertension Self-Care Profile among older patients with hypertension in China.
How do the Self-Care of Hypertension Inventory (SC-HI) and Hypertension Self-Care Profile (HBP SCP) compare in assessing self-care among older adults with hypertension in China?
Cross-Sectional (n=220)
Yes
How do the Self-Care of Hypertension Inventory (SC-HI) and Hypertension Self-Care Profile (HBP SCP) compare in assessing self-care among older adults with hypertension in China?
Absolute Event Rate: 0.838% vs 0.754%
p-value: p=<0.05
Both the SC-HI and HBP SCP are reliable and valid tools for assessing hypertension self-care in older Chinese adults, with the HBP SCP being slightly more precise.
HBP SCP may offer modestly superior accuracy for self-care assessment in older Chinese adults with hypertension; leaves open need for prospective validation before clinical adoption.
AIM: To test and compare the Self-Care of Hypertension Inventory (SC-HI) and Hypertension Self-Care Profile (HBP SCP) among older patients with hypertension in China. DESIGN: A cross-sectional observational study. METHODS: A convenience sampling of 220 older adults (120 male patients and 100 female patients) with hypertension and a mean age of 73.74 years was surveyed using the Chinese version of SC-HI, the Chinese version of HBP SCP and the Chinese version of Exercise of Self-Care Agency Scale (ESCA) during July-September 2019. Psychometric analyses and Receiver Operating Characteristic curve analyses were performed on the collected data. RESULTS: The Cronbach's α of SC-HI and HBP SCP was 0.858 and 0.953, respectively. The Pearson's coefficients between the SC-HI total score and the ESCA total score, the HBP SCP total score and the ESCA total score were 0.494 and 0.700, respectively. The satisfactory sensitivity, specificity, cut-off point and Area under the curve of SC-HI were 0.8292, 0.5495, 120.5 and 0.754, respectively. As for HBP SCP, the values were 0.7907, 0.7582, 169.5 and 0.838, respectively. There was no significant difference between these two scales. Each has its own characteristics. However, the HBP SCP is more precise and effective for measuring self-care ability in older patients.

Zhao et al. (2022) conducted a cross-sectional in Hypertension (n=220). Hypertension Self-Care Profile (HBP SCP) vs. Self-Care of Hypertension Inventory (SC-HI) was evaluated on Area under the curve (AUC) for predicting high self-care ability (p=<0.05). The HBP SCP scale (AUC 0.838) demonstrated significantly better diagnostic accuracy than the SC-HI scale (AUC 0.754) for assessing self-care ability in older Chinese adults with hypertension.
