Increased violent events happen in the general hospitals in China and yet non-psychiatric departments do not have tools for violence-tendency screening.
The current study developed and evaluated two Inpatient Psychological Experience Questionnaires (IPEQs) for the screening of violence-related six mental health disorders: (Inpatient Psychological Experience Questionnaire-1 (IPEQ-1): anxiety, depression and suicidality; Inpatient Psychological Experience Questionnaire-2 (IPEQ-2): paranoid personality disorder, emotionally unstable personality disorder and histrionic personality disorder). Two initial IPEQs (IPEQ-1: 37 items and IPEQ-2: 30 items) were developed and assessed by domain experts. Then 1210 inpatients were recruited and divided into three groups (160, 450 and 600 samples, respectively) for IPEQs item selection and evaluation. During the two-stage item selection, three statistical methods including Pearson's correlation coefficient, exploratory factor analysis and item response theory were applied. For the item evaluation, Cronbach's alpha coefficient, test-retest reliability, criterion-related validity and construct validity of the final questionnaires were measured.
Twelve items were selected for each IPEQs. Cronbach's alpha coefficients were 0.91 and 0.78 for IPEQ-1 and IPEQ-2, respectively. Test-retest replication ratios were 0.95 and 0.87 for IPEQ-1 and IPEQ-2, respectively. Correlation coefficients between different disorders and their related-tools scores were [0.51, 0.44] and [0.40, 0.44] for IPEQ-1 and IPEQ-2, respectively and were significant (P < 0.01). Confirmatory factor analysis supported the validity of the final IPEQs (P < 0.05), and the model fit index met the criterion generally.
The IPEQs developed in this study could be effective and easy-to-use tools for screening inpatients with violence-intendancy in non-psychosomatic departments.
中国综合医院暴力事件频发，但非精神科科室缺乏暴力倾向筛查工具。
本研究开发并评估了两种用于筛查与六种心理健康障碍相关的暴力问题的住院患者心理体验问卷（IPEQs）：（住院患者心理体验问卷-1（IPEQ-1）：焦虑、抑郁和自杀意念；住院患者心理体验问卷-2（IPEQ-2）：偏执型人格障碍、情绪不稳定型人格障碍和表演型人格障碍）。两个初始的 IPEQs（IPEQ-1：37 项，IPEQ-2：30 项）由领域专家制定和评估。然后招募了 1210 名住院患者，并将其分为三组（分别为 160、450 和 600 个样本）进行 IPEQs 项目选择和评估。在两阶段项目选择过程中，使用了三种统计方法，包括皮尔逊相关系数、探索性因素分析和项目反应理论。对于项目评估，测量了最终问卷的克朗巴赫 α系数、重测信度、效标关联效度和结构效度。
每个 IPEQs 都选择了 12 项。IPEQ-1 和 IPEQ-2 的克朗巴赫 α系数分别为 0.91 和 0.78。IPEQ-1 和 IPEQ-2 的重测复制率分别为 0.95 和 0.87。不同障碍与相关工具评分之间的相关系数分别为 IPEQ-1 为[0.51，0.44]和 IPEQ-2 为[0.40，0.44]，均具有统计学意义（P<0.01）。验证性因子分析支持最终 IPEQs 的有效性（P<0.05），且模型拟合指数总体上符合标准。
本研究开发的 IPEQs 可作为非精神科科室筛查有暴力倾向住院患者的有效且易于使用的工具。
