The Translation, Reliability and Validity of the Chinese Version of the Hill–Bone Compliance to High Blood Pressure Therapy Scale in Adults with Hypertension

Abstract

Objective

To assess the reliability and validity of the Chinese version of the Hill–Bone compliance to high blood pressure therapy scale (HBTS) for use in adults with hypertension in China.

Methods

To develop a Chinese version of the study scale, it was translated into Chinese then back-translated into English. The final version was used in a survey conducted between Jan and June 2019 in a hospital in Xi’an, China. Reliability was assessed by using the Cronbach’s alpha as a measure of analyzing the internal consistency. Exploratory factor analysis (EFA) was performed to assess the validity of the Chinese scale.

Results

The EFA revealed a four-component structure representing two of medication taking; appointment keeping and reduced sodium intake. Percentages of explained variance were 37.55%, 52.77%, 65.24% and 73.97%, respectively. All questions have factor loadings >0.4. The Cronbach’s alpha score for the entire questionnaire was 0.857.

Conclusion

The Chinese Hill–Bone scale (HBTS-C) is a valid and reliable instrument for measuring adherence among Chinese with hypertension. Use of this screening tool for the assessment of adherence to hypertension treatment is recommended.
