Insights

This study validated a Persian version of the revised heart failure compliance questionnaire (RHFCQ) for Iranian heart failure patients. The translated RHFCQ demonstrates good validity and moderate reliability for assessing patient adherence.

Area of Science:

  • Cardiology
  • Health Psychology
  • Medical Sociology

Background:

  • Health-related behavior compliance is a significant challenge for heart failure (HF) patients.
  • Assessing adherence to medical advice is crucial for managing HF outcomes.
  • Existing tools may not adequately capture the nuances of compliance in diverse cultural contexts.

Purpose of the Study:

  • To translate and validate the Revised Heart Failure Compliance Questionnaire (RHFCQ) into Persian.
  • To evaluate the psychometric properties of the Persian RHFCQ in Iranian HF patients.
  • To provide a reliable and valid instrument for measuring compliance in this population.

Main Methods:

  • Methodological study involving forward-backward translation of the RHFCQ.
  • Content validity assessed by 12 experts using the Content Validity Index (CVI).
  • Internal consistency evaluated using Cronbach's alpha; test-retest reliability assessed with the Intraclass Correlation Coefficient (ICC) in 150 HF patients.

Main Results:

  • The Persian RHFCQ showed high CVI scores (0.833–1.000), indicating good content validity.
  • Cronbach's alpha for internal consistency was 0.629, improving to 0.655 after item modification.
  • Test-retest reliability, measured by ICC, was acceptable at 0.576.

Conclusions:

  • The modified Persian RHFCQ is a valid and reliable tool for assessing compliance in Iranian heart failure patients.
  • The questionnaire is user-friendly, demonstrating good validity and acceptable moderate reliability.
  • This instrument can aid healthcare providers in monitoring and improving patient adherence to treatment regimens.

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

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 III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
