Date and code for "Development and validation of a risk prediction model for depressive symptoms in patients with arthritis based on the health ecology model"

Dataset Description This repository contains replication materials for the study entitled Development and validation of a risk prediction model for depressive symptoms in patients with arthritis based on the health ecology model. Using publicly available survey data, this study aims to develop and validate a risk prediction model for depressive symptoms among arthritis patients. The materials include: **Data**: A cleaned dataset derived from the China Health and Retirement Longitudinal Study (CHARLS). This dataset is a processed subset of the original survey data and can be directly applied to statistical analysis. **Code**: R scripts for the development and validation of the risk prediction model. ## Data Source: The dataset provided here is derived from the following publicly available source: China Health and Retirement Longitudinal Study (CHARLS): https://charls.pku.edu.cn/ ##License: The code is shared under the MIT License. Data reuse must comply with the terms and conditions of the original CHARLS dataset provider. ##How to Use: 1. Download the code and data files. 2. Open the corresponding script in RStudio. 3. Modify the file paths as needed, and run the scripts to reproduce the model.
