Description

Health-Related Quality of Life (HRQOL) refers to individuals’ subjective assessments of their health and the impact of their health on daily life. The Healthy Days Symptoms (HDS-5) tool assesses the duration and intensity of symptoms affecting quality of life.

Data Analysis and Use

Data analysis from the HRQOL-HDS-5 includes:
Scoring: Participants report the duration and intensity of their symptoms over specific time periods.
Statistical Analysis:Descriptive Statistics: Mean and standard deviation are used to determine overall quality of life.
Correlation: Examining the relationship between quality of life and factors such as age, gender, or socioeconomic conditions.
Comparative Analysis: Comparisons between different groups (e.g., patients with different conditions) to highlight differences in quality of life.

Objective

The objective of the HRQOL-HDS-5 tool is to understand the impact of symptoms on individuals’ quality of life, identify factors that affect well-being, and provide data for improving healthcare interventions.

Calibration

Calibration of the HRQOL-HDS-5 includes:
Cross-Cultural Studies: Testing the tool in various cultural contexts to ensure appropriate and accurate application.
Reliability Analysis: Using techniques such as Cronbach’s alpha to ensure the consistency of the questions.
Validity Testing: Checking the tool’s ability to reflect participants’ actual experiences regarding their quality of life.
