The main objective of the study was to determine the psychometric properties (mainly, validity and reliability) of the French language version of the brief Quality of Life Interview (QoLI). That instrument evaluates both the subjective and objective aspects of quality of life.
128 patients fulfilling the DSM IV criteria for schizophrenia were included. Quality of life was evaluated using the brief QoLI. Schizophrenic symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS). The validity of the internal structure of the QoLI was investigated by means of item analysis, study of the correlations between the items and between the item-dimensions and principal component analysis addressing the subjective fields. The validity of the external structure was mainly investigated through the nomological validity study. The reliability of the scale was evaluated by studying the internal consistency. In addition, the acceptability of the scale was documented.
The results of the study of the validity of the internal structure confirmed the pertinence of the pre-defined fields, particularly the subjective fields. Only some of the subjective fields of the QoLI showed significant correlations with the PANSS sub-scales. The acceptability of the scale was satisfactory.
The psychometric properties of the French language version of the brief QoLI appeared satisfactory. The brief QoLi was shown to be an easily used instrument for assessment of the various objective and subjective aspects of the quality of life of schizophrenic patients.
本研究的主要目的是确定简易生活质量访谈(QoLI)法语版的心理测量特性(主要是效度和信度)。该工具评估生活质量的主观和客观方面。
纳入128名符合精神分裂症DSM-IV标准的患者。使用简易QoLI评估生活质量。使用阳性和阴性症状量表(PANSS)评估精神分裂症症状。通过项目分析、项目之间以及项目维度与涉及主观领域的主成分分析之间的相关性研究,调查QoLI内部结构的效度。外部结构的效度主要通过效标效度研究进行调查。通过研究内部一致性评估量表的信度。此外,记录了量表的可接受性。
内部结构效度研究结果证实了预定义领域的相关性,特别是主观领域。QoLI的一些主观领域仅与PANSS子量表显示出显著相关性。量表的可接受性令人满意。
简易QoLI法语版的心理测量特性似乎令人满意。简易QoLi被证明是一种易于使用的工具,可用于评估精神分裂症患者生活质量的各种客观和主观方面。
