The Decisional Conflict Scale (DCS, 16 items, 5 dimensions) designed to measure the level of decisional conflict experienced by patients making health care decisions has not yet been validated in French.
A national sample of French cancer patients (n=644) facing the decision to undergo BRCA genetic testing was tested for this purpose, including a control group and an experimental group who had received an information booklet. Reliability and criterion validity were investigated. To check the validity of the factors selected, an exploratory factor analysis was then conducted, followed by confirmatory factor analyses.
Reliability was satisfactory (alpha=0.913). Women who definitely wanted to undergo genetic testing showed significantly lower DCS scores than uncertain women (p<0.001). Exploratory factor analysis suggested an optimal 4-dimensional model. In the control group, confirmatory factor analyses showed that the French model was more accurate than the original one. When the decision-making conflicts decreased (in the experimental group), both models yielded only fairly accurate indices.
The French version of the DCS was found to give a reliable overall score. However, special care should be taken when using the individual subscores. In addition, it is necessary to take into account the context in which the decision-making occurs.
决策冲突量表（DCS，16项，5个维度）旨在衡量做出医疗保健决策的患者所经历的决策冲突程度，其法语版本尚未经过验证。
为此对法国癌症患者的全国样本（n = 644）进行了测试，这些患者面临是否接受BRCA基因检测的决策，包括一个对照组和一个收到信息手册的实验组。对可靠性和效标效度进行了调查。为检验所选因素的有效性，随后进行了探索性因素分析，接着是验证性因素分析。
可靠性令人满意（α = 0.913）。明确希望进行基因检测的女性的DCS得分显著低于不确定的女性（p < 0.001）。探索性因素分析表明最佳的4维模型。在对照组中，验证性因素分析表明法语模型比原始模型更准确。当决策冲突减少时（在实验组中），两个模型得出的指标都只是相当准确。
发现DCS的法语版本给出的总体得分可靠。然而，使用各个子分数时应格外小心。此外，有必要考虑决策发生的背景。
