The Mini-Mental test was developed to assess cognitive impairment in adults. It is structured under five main categories: orientation, registration memory, attention and calculation, recall, and language. The test is scored on a total of 30 points. Individuals scoring 17 or below are classified as having severe dementia, those scoring between 18 and 23 are classified with mild dementia, and individuals scoring between 24 and 30 are considered not to have dementia.

The MacNew Heart Disease-Specific Quality of Life Questionnaire is an internationally recognized tool for measuring health-related quality of life in patients with Coronary Artery Disease (CAD).

The questionnaire is designed to assess how physical, emotional, and social functions, as well as daily activities, are affected by CAD. The questionnaire consists of three subscales: physical limitation, emotional function, and social function, with a total of 27 items. Subscale scores are calculated by averaging the responses to the relevant items. For each subscale and for the total score, the lowest possible score is 1 and the highest is 7, with higher scores indicating better quality of life.

It is a mortality scoring system that includes 19 comorbidity diagnostic groups. This index is frequently used as an assessment tool for evaluating comorbidities. A score of "1 point" is assigned for the presence of myocardial infarction, congestive heart failure, peripheral vascular diseases, cerebrovascular disease, dementia, chronic pulmonary disease, connective tissue disease, ulcer disease, mild liver disease, and diabetes. A score of "2 points" is given for conditions such as hemiplegia, moderate/severe renal disease, diabetes with end-organ damage, tumors, leukemia, and malignant lymphoma. A score of "3 points" is assigned for moderate/severe liver disease, and "6 points" is given for the presence of metastatic solid tumors and AIDS. The total score is calculated by summing the individual scores, with higher scores indicating more serious conditions and a worse prognosis.

The Minnesota Living with Heart Failure Questionnaire consists of 21 items that examine the physical and emotional dimensions of heart failure. Items 2, 3, 4, 5, 6, 7, 12, and 13 assess the physical dimension, while items 17, 18, 19, 20, and 21 assess the emotional dimension. Each item is scored on a scale from 0 to 5, with a maximum possible score of 105. Higher scores indicate poorer quality of life.

The Fatigue Severity Scale is a questionnaire designed to measure the severity of fatigue over the past week. It consists of 9 items, each rated on a scale from 0 to 7. The total score is obtained by summing the responses to all items and dividing the sum by 9. A score of 4 or higher typically indicates severe fatigue.

The Leicester Cough Questionnaire is a health-related quality of life tool specifically designed for chronic cough. It is a self-administered, easy-to-use form that evaluates the impact of chronic cough on physical, psychological, and social aspects of life. The questionnaire consists of 19 items across these three domains, and it uses a 7-point Likert scale for responses.

Higher scores on the LCQ indicate that the individual is less affected by the cough, reflecting better overall health. The total score is the sum of the scores from the physical, psychological, and social domains.
