Research demonstrates that anxiety elevates the risk of blood donors experiencing adverse events, which in turn deters the performance of repeat blood donations. Identifying donors suffering from heightened state anxiety is important to assess the impact of evidence-based interventions. This study analyzed the appropriateness of a shortened version of the state subscale of the State-Trait Anxiety Inventory (STAI) in a blood donation context.
STAI-State questionnaire data were collected from two separate samples of Australian blood donors (n = 919 and n = 824 after cleaning). Responses to demographic, donation history, and adverse reaction questions were also obtained. Identification of items and analysis was performed systematically to assess and compare internal reliability and content, construct, convergent, and criterion validity of three potential short-form state anxiety scales.
Of the three short-form scales tested, STAI-State six-item scale demonstrated the best metric properties with the least number of items across both sample groups. Cronbach's alpha was acceptable (α = 0.844 and α = 0.820), correlated positively with the original measure (r = 0.927 and r = 0.931) and criterion-related variables, and maintained the two-dimension factorial structure of the original measure.
The six-item short version of the STAI-State subscale presented the most reliable and valid scale for use with blood donors. A validated donor anxiety tool provides a standardized assessment and record of donor anxiety to gauge the effectiveness of ongoing efforts to enhance the donation experience.
研究表明，焦虑会增加献血者发生不良事件的风险，进而阻碍重复献血行为。识别出状态焦虑水平较高的献血者对于评估循证干预措施的影响至关重要。本研究分析了状态-特质焦虑问卷（STAI）状态分量表的一个缩短版本在献血情境中的适用性。
从澳大利亚献血者的两个独立样本中收集了STAI状态问卷数据（清理后n = 919和n = 824）。还获取了对人口统计学、献血历史和不良反应问题的回答。系统地进行项目识别和分析，以评估和比较三种潜在的简短状态焦虑量表的内部信度、内容效度、结构效度、收敛效度和效标效度。
在测试的三个简短量表中，STAI状态六项目量表在两个样本组中项目数量最少，表现出最佳的计量学特性。克朗巴哈系数可接受（α = 0.844和α = 0.820），与原始量表呈正相关（r = 0.927和r = 0.931）以及与效标相关变量呈正相关，并保持了原始量表的二维因子结构。
STAI状态分量表的六项目简短版本是用于献血者的最可靠、有效的量表。一个经过验证的献血者焦虑工具可为献血者焦虑提供标准化评估和记录，以衡量当前为改善献血体验所做努力的效果。
