The quality of life in epilepsy inventory (QOLIE-89) is the most comprehensive and widely used instrument for assessment of the quality of life of patients with epilepsy.
To prove that the Bulgarian version of QOLIE-89 shows good reliability and validity.
The study included 35 patients with refractory epilepsy: 20 women (57.14%) and 15 men (42.86%) at the mean age of 43.11 +/- 2.38 years and mean duration of epilepsy 22.46 +/- 2.05 years. All respondents completed QOLIE-89 twice at an interval of one to three weeks; they also completed QOLIE-31 once.
Cronbach's alpha was between 0.90 and 0.92 for all subscales, the mean assessment score was 0.91. These results, the high Spearman-Brown coefficient (0.90) and the low mean inter-item correlation (0.33) suggest that the Bulgarian version of QOLIE-98 shows excellent internal consistency and high reliability. This is supported by the high coefficient of correlation (0.83-0.98) between the subscales scores and the overall assessment of the quality of life in the two completions of the questionnaire. The questionnaire proved to be valid based on the strong correlation we found between the overall assessment score (0.91) of QOLIE-31 and QOLIE-89 and the subscales of seizure worry, overall quality of life, energy/fatigue and overall scores--all in the range of 0.95-1.00. The correlations of coefficients for the other subscales were between 0.69-0.86.
The psychometric properties of the Bulgarian version of QOLIE-98 are good; they are similar to those of the original American version and the validated Norwegian and Chinese versions. It shows high reliability and validity and can be used to assess the quality of life of elderly people with epilepsy.
癫痫患者生活质量量表（QOLIE - 89）是评估癫痫患者生活质量最全面且应用最广泛的工具。
证明保加利亚语版的QOLIE - 89具有良好的信度和效度。
该研究纳入了35例难治性癫痫患者，其中20例女性（57.14%），15例男性（42.86%），平均年龄43.11±2.38岁，平均癫痫病程22.46±2.05年。所有受访者在1至3周的间隔内完成两次QOLIE - 89问卷；他们还完成了一次QOLIE - 31问卷。
所有分量表的克朗巴哈系数在0.90至0.92之间，平均评分为0.91。这些结果、较高的斯皮尔曼 - 布朗系数（0.90）以及较低的平均项目间相关性（0.33）表明，保加利亚语版的QOLIE - 98具有出色的内部一致性和高信度。问卷两次填写的分量表得分与生活质量总体评估之间的高相关系数（0.83 - 0.98）也支持了这一点。基于我们发现的QOLIE - 31和QOLIE - 89的总体评估得分（0.91）与癫痫发作担忧、生活质量总体、精力/疲劳以及总分等分量表之间的强相关性（范围均在0.95 - 1.），该问卷被证明是有效的。其他分量表的相关系数在0.69 - 0.86之间。
保加利亚语版QOLIE - 98的心理测量特性良好；与原始美国版以及经验证的挪威语和中文版相似。它具有高信度和效度，可用于评估老年癫痫患者的生活质量。
