Insights

The Persian version of the heart failure-specific health literacy scale is a valid and reliable tool for assessing health literacy (HL) in heart failure patients. This validated instrument is crucial for improving patient outcomes.

Area of Science:

  • Cardiology
  • Health Literacy Research
  • Psychometrics

Background:

  • Health literacy (HL) significantly impacts health outcomes in heart failure (HF) patients.
  • Culturally appropriate and valid instruments are essential for studying HL.
  • The study aimed to validate the Persian version of the heart failure-specific health literacy scale (HF-Specific HL Scale).

Purpose of the Study:

  • To validate the Persian translation of the HF-Specific HL Scale.
  • To ensure the scale is a reliable and culturally relevant tool for measuring health literacy in Iranian heart failure patients.

Main Methods:

  • Translation of the HF-Specific HL Scale into Persian using the forward-backward procedure.
  • Assessment of content, face, and construct validity.
  • Evaluation of reliability using Cronbach's alpha and test-retest methods.
  • Data analysis with SPSS and Smart PLS software.

Main Results:

  • Confirmatory factor analysis supported the three-factor model.
  • Convergent and divergent validity were confirmed.
  • The structural model demonstrated good fit (R-square > 0.43, path coefficient > 0.65).
  • High internal consistency (Cronbach's α > 0.70) and good test-retest reliability (0.78-0.90) were achieved.

Conclusions:

  • The Persian HF-specific HL scale is a reliable and valid instrument for assessing health literacy in heart failure patients.
  • The validated scale can be used to measure health literacy in this population.
  • Further research is needed to determine the scale's sensitivity and specificity.

Health Literacy01:21

Health Literacy

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure I: Introduction01:27

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...
