Development and Psychometric Validation of HIPER-Q to Assess Knowledge of Hypertensive Patients in Cardiac Rehabilitation

Abstract

BackgroundThe absence of instruments capable of measuring the level of knowledge of hypertensive patients in cardiac rehabilitation programs about their disease reflects the lack of specific recommendations for these patients.ObjectiveTo develop and validate a questionnaire to evaluate the knowledge of hypertensive patients in cardiac rehabilitation programs about their disease.MethodsA total of 184 hypertensive patients (mean age 60.5 ± 10 years, 66.8% men) were evaluated. Reproducibility was assessed by calculation of the intraclass correlation coefficient using the test-retest method. Internal consistency was assessed by the Cronbach’s alpha and the construct validity by the exploratory factorial analysis.ResultsThe final version of the instrument had 17 questions organized in areas considered important for patient education. The instrument proposed showed a clarity index of 8.7 (0.25). The intraclass correlation coefficient was 0.804 and the Cronbach’s correlation coefficient was 0.648. Factor analysis revealed five factors associated with knowledge areas. Regarding the criterion validity, patients with higher education level and higher family income showed greater knowledge about hypertension.ConclusionThe instrument has a satisfactory clarity index and adequate validity, and can be used to evaluate the knowledge of hypertensive participants in cardiac rehabilitation programs.

Does Hypertension Knowledge Influence Levels of Physical Activity in Hypertensive Patients From a Southern Brazilian Community?

“…38 With respect to knowledge about HP, most patients (50.8%) were classified in the category of "acceptable knowledge". These results are similar to those of other studies 21,39 and reflect the importance of assessing knowledge about health and formulating hypotheses that may elucidate the determining factors for information gaps. It is also noteworthy that no patient presented an optimal level of knowledge about the disease, according to the classification of the instrument.…”

“…It is also noteworthy that no patient presented an optimal level of knowledge about the disease, according to the classification of the instrument. 21 Therefore, patient knowledge is a central component in the treatment of HP and is associated with successful selfmanagement of the disease and behavioral changes. 16,40 Health education interventions can result in significant reductions in risk factors associated with lifestyle diseases, such as HP.…”

“…After completion of all questions, the sum of the scores obtained represent the average total knowledge, and the maximum score of 51 points represents the "perfect" knowledge. 21 Finally, the level of PA was assessed using a pedometer (Power Walker TM ® Model PW-610/611). The equipment was programmed to store the number of steps taken for 24 hours.…”

“…2021;[online].ahead print, PP.0-0 men (27.6%). Median knowledge about HP was 32 (10) points, which means acceptable knowledge according to HIPER-Q 21. The correlation tests of knowledge about HP with age, BMI and level of PA are illustrated in Table2.…”

Development of an instrument to evaluate the knowledge that the patient with hepatic cirrhosis has about his disease and treatment

“…The work of Bonin et al 18 , constructed a questionnaire to measure the knowledge of the patient with heart failure. The research of Zulianello et al 19 , who constructed and validated a psychometric scale to assess the knowledge of hypertensive patients. Maciel et al 20 developed a belief scale on mental illness.…”
