一、项目介绍
选题背景
随着现代社会生活节奏的加快和竞争压力的增大，心理压力问题已成为影响公众健康的重要因素。根据世界卫生组织发布的《全球心理健康状况报告》显示，全球约有27%的成年人经历过不同程度的心理压力困扰，而美国心理学会的年度压力调查数据表明，超过60%的受访者表示工作和生活压力对其身心健康造成了显著影响。国内相关研究机构的调研结果显示，我国城市居民中有接近40%的人群处于中高等压力状态，压力相关的心理疾病发病率呈现逐年上升趋势。传统的压力评估方法主要依赖心理量表测试和专业医生诊断，存在评估周期长、主观性强、难以实现连续监测等局限性。伴随着可穿戴设备技术的快速发展和智能手机的广泛普及，人们的生理指标、行为模式、社交活动等数据得以大量采集和记录，这些数据蕴含着丰富的压力状态信息。同时，大数据处理技术特别是Apache Spark分布式计算框架的日趋成熟，为处理和分析海量多维度压力相关数据提供了强有力的技术支撑，使得构建智能化、自动化的压力检测分析系统成为现实可能。
选题意义
本系统的建设具有重要的理论价值和广泛的实际应用意义。从技术创新层面来看，该系统将Hadoop分布式存储架构与Spark大数据处理引擎相结合，探索了大数据技术在心理健康数据分析领域的深度应用，为相关技术的跨领域融合提供了宝贵的实践经验和技术参考。从健康管理角度分析，系统通过整合个体的生理指标、行为模式、人格特质等多维度数据，能够建立起科学的压力状态量化评估模型，这对于早期识别和筛查高压力风险人群具有重要价值，可以帮助医疗机构和健康管理部门更及时地发现潜在的心理健康问题。从社会效益角度考虑，该系统的推广应用能够降低传统压力评估的人力成本和时间成本，提高压力检测的效率和准确性，为构建覆盖面更广的心理健康监测网络奠定技术基础。对于个人用户而言，系统提供的个性化压力分析报告和健康建议，能够帮助用户更好地了解自身的压力状况和影响因素，从而采取针对性的调节措施，改善生活质量和心理健康水平。
