The aim of our study was to validate the Spanish version of the Insight Scale (IS) (Birchwood et al., 1994), a multidimensional self-report insight scale.
Observational study in a sample of patients with psychosis. A translation-backtranslation of the original scale was elaborated. Feasibility was calculated. Concurrent criteria validity with item 12 of PANSS, construct convergent and divergent validity with DAI and BPRS were calculated. IS scores between voluntary and involuntary inpatients were used for discriminant validity. Factor analysis, temporal reliability and internal consistency were also examinated.
The sample consisted of 61 patients. Interclass Correlation Coeficient (ICC) between item 12 of PANSS and IS was 0.49. Correlation between IS and DAI, and IS and BPRS was 0.414 (p=0.01) and -0.14 respectively. Difference between mean IS scores of voluntary (8.37) and involuntary inpatients (6.21) was signific (U test Mann-Whitney: 244.5; p=0.005). Three factors were extracted that accounted for 68.32% of variance. Cronbach alpha was 0,717.
The Spanish version of IS is a quick, simple, self-report and multidimensional instrument of insight with satisfactory psychometric properties.
我们研究的目的是验证洞察力量表（IS）（Birchwood等人，1994年）的西班牙语版本，这是一种多维自我报告洞察力量表。
对一组精神病患者进行观察性研究。对原始量表进行了翻译回译。计算了可行性。计算了与阳性和阴性症状量表（PANSS）第12项的同时效度标准，与缺陷评估量表（DAI）和简明精神病评定量表（BPRS）的结构收敛效度和发散效度。使用自愿住院患者和非自愿住院患者的IS得分进行判别效度分析。还检验了因子分析、时间可靠性和内部一致性。
样本包括61名患者。PANSS第12项与IS之间的组内相关系数（ICC）为0.49。IS与DAI之间的相关性以及IS与BPRS之间的相关性分别为0.414（p = 0.01）和-0.14。自愿住院患者（8.37）和非自愿住院患者（6.21）的平均IS得分差异具有统计学意义（曼-惠特尼U检验：244.5；p = 0.005）。提取了三个因子，解释了68.32%的方差。克朗巴哈α系数为0.717。
IS的西班牙语版本是一种快速、简单、自我报告的多维洞察力工具，具有令人满意的心理测量学特性。
