The aim of this study was to adapt the instrument 'Good Nursing Care Scale for Patients' to Swedish conditions as a measure of patients' satisfaction, as well as estimating its reliability and validity. Following a pilot test, discussions in the author group, testing for readability among patients and judgement of content validity by a panel of experts, the final version was reduced to 72 items focusing on good caring. The refined instrument was assessed for internal consistency in 447 surgical in-patients, for 2 week test-retest reliability in 100 patients and subjected to orthogonal principal components factor analysis with varimax rotation, followed by second-order factor analysis. The internal consistency item-item correlation coefficient ranged from 0.15 to 0.91, correlation between each item and the total scale was >or=0.30 for 70 items, Cronbach's alpha coefficient for the final scale was 0.79 and test-retest reliability was 0.75. An orthogonal principal components factor analysis with varimax rotation was conducted on the final 71 items and the 15 first-order factors with eigenvalues >or=1 explained 66% of the total variance. A second-order factor analysis of these 15 factors as items resulted in a seven-factor solution. The total variance explained by the seven factors was 79%. Cronbach's alpha coefficient for the seven factors ranged between 0.32 and 0.95. The instrument seems reliable and valid to assess the patients' satisfaction with what happened during their hospital stay. To confirm the factor structure and improve factor consistency additional development and testing is suggested.
本研究的目的是将“患者优质护理量表”调整至瑞典的情况，作为衡量患者满意度的指标，并评估其信度和效度。经过预试验、作者组讨论、对患者进行可读性测试以及由专家小组判断内容效度后，最终版本缩减至72项，重点关注优质护理。对447名外科住院患者评估了该优化量表的内部一致性，对100名患者进行了为期2周的重测信度测试，并进行了具有方差最大化旋转的正交主成分因子分析，随后进行二阶因子分析。内部一致性项目间相关系数范围为0.15至0.91，70个项目中每个项目与总量表的相关系数≥0.30，最终量表的克朗巴赫α系数为0.79，重测信度为0.75。对最终的71个项目进行了具有方差最大化旋转的正交主成分因子分析，特征值≥1的15个一阶因子解释了总方差的66%。对这15个因子作为项目进行二阶因子分析，得到了一个七因子解决方案。这七个因子解释的总方差为79%。这七个因子的克朗巴赫α系数范围在0.32至0.95之间。该量表似乎在评估患者对住院期间所发生事情的满意度方面具有信度和效度。建议进行进一步的开发和测试以确认因子结构并提高因子一致性。
