Heatwave Risk Perception and Its Determinants: Empirical Evidence from Pakistan

This dataset supports the study “Heatwave Risk Perception among Vulnerable Communities in Pakistan”, which investigates public perception and determinants of heatwave risk across Pakistan. The dataset was collected to better understand how individuals perceive heatwave-related risks, particularly in the context of increasing frequency and intensity of extreme heat events due to climate change. A total of 686 registered volunteers from the Alkhidmat Foundation Pakistan participated in an online survey. The questionnaire assessed demographic characteristics, heatwave experiences, knowledge, attitudes, and perceptions of heat-related risks. The survey also included items related to perceived vulnerability, perceived severity, perceived benefits, cues to action, and other determinants influencing heatwave risk perception. The dataset includes: Raw and cleaned survey responses (anonymized). Variable descriptions and coding information. Construct scales used to compute the Heatwave Risk Perception Index (HRPI), developed from the first two constructs of the Health Belief Model (perceived vulnerability and perceived severity). Socio-demographic variables and indicators used in univariate and multivariate logistic regression analyses. Key findings from the associated study indicate that 57.73% of respondents demonstrated a high heatwave risk perception. Factors such as ethnicity, previous heatwave experience, awareness of heatwave plans, experienced maximum temperature, sleep disruption, perception of future heatwave increase, and personal or relatives’ health concerns were found to significantly influence heatwave risk perception. This dataset can be used for further research on climate risk communication, behavioral adaptation, and public health preparedness in the context of extreme heat events in South Asia.本数据集用于支撑题为《巴基斯坦脆弱社区的热浪风险认知》（Heatwave Risk Perception among Vulnerable Communities in Pakistan）的研究，该研究旨在调查巴基斯坦境内民众的热浪风险认知及其影响因素。本数据集的采集旨在更全面地理解个体对热浪相关风险的认知模式，尤其是在气候变化导致极端高温事件发生频率与强度持续增加的背景下。 总计686名来自巴基斯坦阿尔赫德马特基金会（Alkhidmat Foundation Pakistan）的注册志愿者参与了本次线上问卷调查。问卷涵盖人口统计学特征、热浪相关经历、知识储备、态度倾向以及热浪风险认知等多个维度，同时包含感知易感性、感知严重性、感知收益、行动线索等各类影响热浪风险认知的相关条目。 本数据集涵盖以下内容： 1. 经匿名化处理的原始与清洗后的问卷回复数据； 2. 变量说明与编码信息； 3. 用于构建热浪风险感知指数（Heatwave Risk Perception Index, HRPI）的构念量表，该指数基于健康信念模型（Health Belief Model, HBM）的前两个构念——感知易感性与感知严重性开发而成； 4. 用于单因素与多因素逻辑斯蒂回归分析的社会人口学变量与指标。 该关联研究的核心发现显示，57.73%的受访者呈现出较高水平的热浪风险认知。研究表明，民族属性、既往热浪经历、对热浪应对预案的知晓程度、亲历的最高气温、睡眠中断情况、对未来热浪频次增长的认知，以及个人或亲属的健康担忧等因素，均会对热浪风险认知产生显著影响。 本数据集可用于南亚地区极端高温事件背景下的气候风险传播、行为适应与公共卫生备灾等相关后续研究。
