The Specific Phobia of Vomiting Inventory (SPOVI) is a 14-item instrument measuring behavioral avoidance and threat monitoring associated with emetophobia. The current study aimed to provide a German translation of the SPOVI and examine its psychometric properties and correlates.
N = 441 adults from the general population and N = 465 outpatients with mental disorders completed the SPOVI and other self-report measures. Factor structure, reliability, convergent, and discriminant validity, as well as clinical utility, were investigated.
The German version of the SPOVI had a one-factor structure and high internal consistency in both samples (ωs > 0.90). Large correlations (rs > 0.50) with questionnaires assessing phobic anxiety, general anxiety, illness-related anxiety, and disgust sensitivity supported convergent validity, while relatively low correlations with questionnaires assessing depression, eating disorders or paranoid ideation supported discriminant validity. Among outpatients, those with a specific phobia diagnosis had the highest SPOVI scores.
The German translation of the SPOVI has sound psychometric properties and is a potentially practical clinical screening instrument for emetophobia. PRE-REGISTRATION: https://aspredicted.org/5y6zb.pdf .
呕吐特定恐惧症量表（SPOVI）是一种包含14个条目的工具，用于测量与恐吐症相关的行为回避和威胁监测。本研究旨在提供SPOVI的德文翻译，并检验其心理测量特性及相关性。
441名普通人群中的成年人以及465名患有精神障碍的门诊患者完成了SPOVI及其他自我报告测量。对其因子结构、信度、聚合效度、区分效度以及临床效用进行了研究。
SPOVI德文版在两个样本中均具有单因子结构和较高的内部一致性（ωs＞0.90）。与评估恐惧焦虑、一般焦虑、疾病相关焦虑和厌恶敏感性的问卷具有高度相关性（rs＞0.50），支持聚合效度；而与评估抑郁、饮食失调或偏执观念的问卷相关性相对较低，支持区分效度。在门诊患者中，患有特定恐惧症诊断的患者SPOVI得分最高。
SPOVI德文版具有良好的心理测量特性，是一种潜在实用的恐吐症临床筛查工具。预注册：https://aspredicted.org/5y6zb.pdf 。
