In our study, we aimed to adapt the Suicide Crisis Inventory (SCI), which can be used specifically to assess the acute phase of suicide, to the Turkish population by examining its Turkish validity and reliability in a non-clinical sample.
In this cross-sectional study, a total of 300 university students aged 18-24 years were evaluated online using the Socio-demographic and Clinical Data Form, the SCI, and the Suicide Behavior Questionnaire (SBQ). Criterion validity, discriminative validity, and factor analyses (exploratory and confirmatory) were conducted for the validity of the SCI, and internal consistency and item-total correlations were examined for reliability analyses. Additionally, a linear regression model was constructed to assess the predictive validity of the SCI. The predictive validity of past SCI scores was evaluated using a simple regression model.
When the linear regression model was tested with SCI scores as the independent variable and SBQ scores as the dependent variable [(1-298) = 203.625; = .000], it was found that the independent variable explained 41% of the variance in the dependent variable ( = 0.637; = 0.406). SCI scores significantly predicted SBQ scores ( = 14.270; B = 0.047; Bsth = 0.003; β = 0.647; = .000). In the validity analysis, the items removed from the scale could be evaluated for the total score, as they did not belong to any factor as originally specified. When items were removed, the total item reliability was Cronbach's alpha = 0.981.
We believe that the SCI will be a useful tool in assessing short-term suicide risk in a Turkish sample and in conducting scientific research. The SCI was found to be sufficient for use in a Turkish sample for the evaluation of short-term suicide risk, considering some limitations.
在我们的研究中，我们旨在通过在非临床样本中检验其土耳其语效度和信度，使专门用于评估自杀急性期的自杀危机量表（SCI）适用于土耳其人群。
在这项横断面研究中，使用社会人口学和临床数据表格、SCI以及自杀行为问卷（SBQ）对300名年龄在18 - 24岁的大学生进行在线评估。对SCI的效度进行了效标效度、区分效度和因子分析（探索性和验证性），并对信度分析检验了内部一致性和项目 - 总分相关性。此外，构建了一个线性回归模型来评估SCI的预测效度。使用简单回归模型评估过去SCI分数的预测效度。
当以SCI分数作为自变量、SBQ分数作为因变量对线性回归模型进行检验时[（1 - 298）= 203.625； = 0.000]，发现自变量解释了因变量中41%的方差（ = 0.637； = 0.406）。SCI分数显著预测了SBQ分数（ = 14.270；B = 0.047；Bsth = 0.003；β = 0.647； = 0.000）。在效度分析中，从量表中删除的项目由于不属于最初指定的任何因子，因此可以对总分进行评估。删除项目后，总项目信度为Cronbach's alpha = 0.981。
我们认为SCI将成为评估土耳其样本中短期自杀风险以及进行科学研究的有用工具。考虑到一些局限性，发现SCI足以用于土耳其样本中短期自杀风险的评估。
