Hypertension Knowledge-Level Scale (HK-LS): a study on development, validity and reliability.

Erkoc SB, Isikli B, Metintas S, Kalyoncu C - Int J Environ Res Public Health (2012)

Bottom Line: The scale ensured internal consistency in reliability and construct validity, as well as stability over time.No correlation was found between knowledge score and working at an income-generating job.The present scale, developed to measure the knowledge level of hypertension among Turkish adults, was found to be valid and reliable.

ABSTRACT
This study was conducted to develop a scale to measure knowledge about hypertension among Turkish adults. The Hypertension Knowledge-Level Scale (HK-LS) was generated based on content, face, and construct validity, internal consistency, test re-test reliability, and discriminative validity procedures. The final scale had 22 items with six sub-dimensions. The scale was applied to 457 individuals aged ≥ 18 years, and 414 of them were re-evaluated for test-retest reliability. The six sub-dimensions encompassed 60.3% of the total variance. Cronbach alpha coefficients were 0.82 for the entire scale and 0.92, 0.59, 0.67, 0.77, 0.72, and 0.76 for the sub-dimensions of definition, medical treatment, drug compliance, lifestyle, diet, and complications, respectively. The scale ensured internal consistency in reliability and construct validity, as well as stability over time. Significant relationships were found between knowledge score and age, gender, educational level, and history of hypertension of the participants. No correlation was found between knowledge score and working at an income-generating job. The present scale, developed to measure the knowledge level of hypertension among Turkish adults, was found to be valid and reliable.
