Researchers developed and tested a new questionnaire that measures how ready heart disease patients are to adopt an anti-inflammatory diet. In a pilot study of 25 patients, the tool successfully classified participants into three readiness stages and demonstrated acceptable internal consistency with a Cronbach’s alpha of 0.73. The questionnaire, available in English and Hindi, helps doctors understand each patient’s readiness for dietary change and can guide personalized support strategies.
Researchers in India created and tested a new questionnaire to measure how ready people with heart disease are to switch to an anti-inflammatory diet, which can help reduce heart problems. The tool, called the Readiness to Change Diet Questionnaire, was developed by adapting an existing assessment and testing it with heart patients. According to Gram Research analysis, the questionnaire successfully identified patients at different stages of dietary change readiness and worked well in both English and Hindi. The study involved 25 participants and showed the tool is easy to understand and useful for helping doctors know which patients need extra support to make healthier eating choices.
Key Statistics
A 2026 pilot study of 25 coronary artery disease patients found that the Readiness to Change Diet Questionnaire successfully classified participants into three stages: 2 in pre-contemplation, 10 in contemplation, and 13 in the action stage.
The adapted Readiness to Change Diet Questionnaire demonstrated acceptable internal consistency with a Cronbach’s alpha of 0.73 in a 2026 pilot test of 25 heart disease patients in India.
In a 2026 validation study, 10 out of 25 heart disease patients required assistance to complete the Readiness to Change Diet Questionnaire, indicating the need for healthcare provider support in some cases.
The Quick Take
- What they studied: Can researchers create a simple questionnaire that measures how willing heart disease patients are to start eating an anti-inflammatory diet?
- Who participated: 25 people with coronary artery disease (blocked heart arteries) in the National Capital Region of India participated in the pilot test. The questionnaire was also reviewed by 6 health experts.
- Key finding: The questionnaire successfully sorted patients into three groups: 2 not ready to change, 10 thinking about changing, and 13 already making changes. The tool showed good internal consistency with a Cronbach’s alpha of 0.73.
- What it means for you: If you have heart disease, this tool could help your doctor understand whether you’re ready to switch to a healthier diet and provide support tailored to your stage of readiness. However, this is an early-stage tool that needs more testing before widespread use.
The Research Details
Researchers took an existing questionnaire designed to measure readiness for treatment changes and adapted it specifically for dietary behavior in heart disease patients. They translated it into Hindi to serve populations in India. The team used an e-Delphi approach, which means experts reviewed the questionnaire multiple times and provided feedback through online rounds. In each round, experts suggested improvements and the researchers made changes based on this feedback. After the experts approved the questionnaire, 25 heart disease patients tested it to see if it was easy to understand and use. The researchers measured how well the questions worked together using a statistical test called Cronbach’s alpha.
Understanding a patient’s readiness to change eating habits is important because people at different stages need different types of support. Someone not thinking about changing needs education, while someone already trying to change needs practical tips. A good measurement tool helps doctors provide the right help at the right time.
This is an early-stage validation study with a small sample size of 25 participants, which limits how much we can generalize the findings. The tool showed acceptable internal consistency (0.73), meaning the questions measure the same concept consistently. The study included expert review and participant feedback, which strengthens the tool’s design. However, the study did not test whether the questionnaire accurately predicts actual dietary behavior changes over time, which would require longer follow-up research.
What the Results Show
The adapted questionnaire successfully classified participants into three stages of readiness to change their diet. Two participants were in the pre-contemplation stage, meaning they were not thinking about changing their diet. Ten participants were in the contemplation stage, meaning they were considering making dietary changes. Thirteen participants were in the action stage, meaning they were already actively trying to eat better. The questionnaire demonstrated acceptable internal consistency with a Cronbach’s alpha of 0.73, indicating that the questions reliably measured readiness to change. Participants found the tool concise and reported that the instructions, definitions, items, and response options were understandable, relevant, and appropriate for their situation.
The research team made several important modifications based on expert feedback. They simplified complex terminology to make the questionnaire easier to understand. They revised the instructions and specific questions to be clearer. They added definitions for key terms. They also simplified the Hindi version to ensure it was equally clear for Hindi-speaking patients. These changes improved the questionnaire’s usability. However, the study noted that 10 out of 25 participants required assistance to complete the questionnaire, suggesting that some patients may need help from healthcare providers when using this tool.
This study adapted the Readiness to Change Questionnaire-Treatment Version, which was originally designed to measure readiness for medical treatments. By modifying it for dietary behavior in heart disease patients, the researchers extended the tool’s usefulness to a new area. The approach of using expert review and participant testing to validate a new questionnaire follows established best practices in health measurement research. The internal consistency score of 0.73 is comparable to other validated health behavior questionnaires.
The study has several important limitations. The sample size of 25 participants is small, so results may not apply to all heart disease patients. The study only tested the questionnaire in one region of India, so it may need adjustment for other populations. The research did not follow patients over time to see if the questionnaire actually predicts whether people will change their eating habits. Some participants needed help completing the questionnaire, which suggests it may not work well for all patients without support. The study did not compare this questionnaire to other existing tools that measure readiness to change.
The Bottom Line
If you have coronary artery disease, talk with your doctor about using this questionnaire to assess your readiness to adopt an anti-inflammatory diet. The tool can help identify your current stage of change and guide conversations about dietary improvements. An anti-inflammatory diet typically emphasizes vegetables, fruits, whole grains, fish, and healthy oils while limiting processed foods and saturated fats. Moderate confidence: This tool shows promise but needs more testing in larger populations before it becomes standard practice.
This tool is designed for people with coronary artery disease and their healthcare providers. It may also be useful for cardiologists, dietitians, and health educators working with heart disease patients. People without heart disease do not need this specific tool, though the general concept of measuring readiness to change applies to many health behaviors.
The questionnaire can immediately help identify your readiness stage, but dietary changes take time. Most people see improvements in heart health markers within 4 to 8 weeks of consistent dietary changes. Significant improvements in inflammation and heart function may take 3 to 6 months or longer.
Frequently Asked Questions
What is an anti-inflammatory diet and why do heart disease patients need it?
An anti-inflammatory diet emphasizes vegetables, fruits, whole grains, fish, and healthy oils while limiting processed foods and saturated fats. Heart disease patients benefit because this eating pattern reduces inflammation in blood vessels and arteries, which helps prevent heart attacks and improves overall heart health.
How does the Readiness to Change Diet Questionnaire help with heart disease management?
The questionnaire identifies which stage of dietary change a patient is in: not thinking about it, considering it, or actively doing it. This helps doctors provide targeted support and education matched to each patient’s readiness level, improving the chances of successful dietary change.
Is this questionnaire ready to use in hospitals and clinics right now?
The questionnaire shows promise and works well in English and Hindi, but this early-stage study involved only 25 patients. Larger studies are needed before it becomes standard practice in most healthcare settings. Talk with your doctor about whether it’s available at your facility.
How long does it take to see health benefits from changing to an anti-inflammatory diet?
Most people notice improvements in inflammation markers within 4 to 8 weeks of consistent dietary changes. Significant improvements in heart function and overall cardiovascular health typically appear within 3 to 6 months or longer, depending on individual factors.
Can this questionnaire predict whether someone will actually stick to a healthier diet?
The study did not test whether the questionnaire predicts actual long-term dietary adherence. While measuring readiness to change is helpful for guiding support, additional research is needed to confirm whether it accurately predicts who will successfully maintain dietary changes.
