To validate the Greek version of the State-Trait Anxiety Inventory (STAI) in a sample of cancer patients.
The scale was administered twice, with a 3-day interval, to 99 eligible patients with cancer. Together with the Greek version of STAI scale, the patients also completed the anxiety subscale from the Hospital Anxiety and Depression scale (HAD).
Factor analysis yielded a three-factor solution, explaining 47.143% of the variance. Cronbach alpha for three scales was between 0.729 and 0.852. Inter-scale correlations were moderate-to-high and ranged from 0.282 to 0.563 (p < 0.0005, p < 0.005). The assessment of the relationships among the Greek STAI scales and HAD-Anxiety showed statistically significant correlations between them (r ranged between 0.428 and 0.596, p < 0.0005). The test/retest reliability of scale (Pearson's 'r'), showed that the coefficient agreement ranged between 0.85 and 0.90 (p < 0.0005). Univariate analysis revealed significant correlations between female gender, metastasis, performance status, chemotherapy, mild opioids and low education level with increased anxiety.
These results support that the Greek version of STAI is an instrument with satisfactory psychometric properties, and is a valid research tool for Greek cancer patients.
在癌症患者样本中验证状态-特质焦虑量表（STAI）的希腊语版本。
对 99 名符合条件的癌症患者进行了两次量表测试，间隔 3 天。除了希腊语版的 STAI 量表外，患者还完成了医院焦虑和抑郁量表（HAD）的焦虑子量表。
因子分析产生了一个三因素解决方案，解释了 47.143%的方差。三个量表的克朗巴赫 alpha 值在 0.729 到 0.852 之间。量表之间的相关性为中度至高度，范围为 0.282 到 0.563（p < 0.0005，p < 0.005）。希腊语 STAI 量表和 HAD-焦虑之间关系的评估显示它们之间存在统计学上显著的相关性（r 范围在 0.428 到 0.596 之间，p < 0.0005）。量表的测试/重测可靠性（Pearson 'r'）显示，系数一致性在 0.85 到 0.90 之间（p < 0.0005）。单变量分析显示，女性性别、转移、表现状态、化疗、轻度阿片类药物和低教育水平与焦虑增加之间存在显著相关性。
这些结果支持希腊语版 STAI 是一种具有令人满意的心理测量特性的工具，是希腊癌症患者有效的研究工具。
