We adapted the Ford Insomnia Response to Stress Test to Turkish (FIRST-T) and validated it.
We randomly divided 774 Turkish university students into two equal groups for exploratory (EFA) and confirmatory factor analysis (CFA). McDonald's omega and Cronbach's alpha values were utilized for reliability analyses. Item response theory (IRT) approach also used for psychometric properties on the full sample. For discriminant validity, study sample were classified into high and low sleep reactivity groups, and their sociodemographic and sleep data were compared.
EFA results suggested a one-factor structure of the FIRST-T, which was confirmed by CFA results. The FIRST-T had solid internal reliability. Item analysis results showed that all the items could distinguish between low and high scorers. This scale showed the same construct (clinical insomnia vs good sleepers) across the sexes in multi-group CFA and differential item functioning results. In the high FIRST-T score group, sleep quality, severity of insomnia, and anxiety scores were higher. In this group, more participants had clinical insomnia according to the Insomnia Severity Index (ISI) and were poor sleepers according to the Pittsburg Sleep Quality Index (PSQI) (p < 0.01).
The FIRST-T has robust psychometric properties that assesses sleep reactivity among university students.
我们对福特应激性失眠反应测试进行了土耳其语改编（FIRST-T）并进行了验证。
我们将774名土耳其大学生随机分为两组，分别进行探索性因素分析（EFA）和验证性因素分析（CFA）。采用麦克唐纳ω系数和克朗巴哈α系数进行信度分析。项目反应理论（IRT）方法也用于对整个样本进行心理测量特性分析。为了检验区分效度，将研究样本分为高睡眠反应性组和低睡眠反应性组，并比较他们的社会人口统计学和睡眠数据。
探索性因素分析结果表明FIRST-T具有单因素结构，验证性因素分析结果证实了这一点。FIRST-T具有可靠的内部信度。项目分析结果表明，所有项目都能区分低分者和高分者。在多组验证性因素分析和项目功能差异结果中，该量表在不同性别间显示出相同的结构（临床失眠者与睡眠良好者）。在FIRST-T高分组中，睡眠质量、失眠严重程度和焦虑得分更高。根据失眠严重程度指数（ISI），该组中更多参与者患有临床失眠，根据匹兹堡睡眠质量指数（PSQI），他们的睡眠质量较差（p<0.01）。
FIRST-T具有强大的心理测量特性，可用于评估大学生的睡眠反应性。
