Psychosocial Predictors and Mental-Health Outcomes in UK Adults: A Two-Wave Longitudinal Survey (10–23 August 2024)

This dataset contains fully anonymised, two-wave survey data from 273 adult, native-English UK residents recruited via the Prolific platform.Time-frame and design: Baseline measures were obtained between 10 and 16 August 2024 (Time 1). The same participants completed follow-up measures exactly one week later, between 17 and 23 August 2024 (Time 2). All 273 respondents took part in both waves, yielding a complete longitudinal panel.Variables collected at Time 1 (baseline):Demographics – age, gender, ethnicity, current employment status.Childhood trauma – total score and five sub-types.Psychosocial resources and vulnerabilities – perceived social support, perceived loneliness, social-network size, previous suicide-related history, subjective socioeconomic status, trait worry, and rumination.Variables collected at Time 2 (one-week follow-up)(reporting period: previous week):Mental-health outcomes – depressive symptoms, anxiety symptoms.Defeat–entrapment outcomes – perceived defeat and entrapment.Stress-related outcomes – perceived stress and stress appraisal.Raw item scores and all derived scale totals are provided. A comprehensive codebook—covering variable names, abbreviations, response formats, and scoring procedures—appears in Worksheet 2 of the file.The current datasets was approved by the Research Ethics Committee of the School of Psychology, University of Leeds (REC reference: PSCETHS-1110), and the main study hypotheses were preregistered at AsPredicted.org (#182080).

本数据集包含经完全匿名化处理的两波追踪调查数据，招募对象为通过Prolific平台招募的273名英国本土成年英语使用者。
时间与研究设计：基线测量于2024年8月10日至16日完成（时间点1）；同一批参与者在整整一周后，即2024年8月17日至23日完成追踪测量（时间点2）。所有273名受访者均参与了两波调查，形成完整的纵向面板数据集。
时间点1（基线）收集的变量包括：人口统计学信息——年龄、性别、族裔、当前就业状态；童年创伤——总分及5个亚型得分；社会心理资源与易感性因素——感知社会支持、感知孤独感、社交网络规模、既往自杀相关史、主观社会经济地位、特质性担忧及反刍思维。
时间点2（一周后追踪）收集的变量（报告周期为过去一周）包括：心理健康结局——抑郁症状、焦虑症状；失败-被困感结局——感知失败与被困感；应激相关结局——感知压力及压力评估。
本数据集提供了原始条目得分及所有派生的量表总分。文件的工作表2中包含一份完整的编码手册，涵盖变量名称、缩写、作答格式及计分流程。本数据集已通过利兹大学心理学院研究伦理委员会批准（伦理审查编号：PSCETHS-1110），本研究的主要假设已在AsPredicted.org平台预先注册（编号：#182080）。
