To translate and validate the Problem-Solving Decision-Making scale instrument into the Portuguese language.
Cross-sectional study.
The Problem-Solving Decision-Making scale was translated from English to Portuguese and then back-translated to obtain a final version. The questionnaire was then applied face-to-face from January to March 2019 in a representative sample of the Portuguese population (n=301 people aged 20 years or more) to validate the Problem-Solving Decision-Making scale in a Portuguese population.
Principal component analysis and Cronbach's alpha.
Principal component analysis was used to evaluate the validity of the internal structure of the scale. The results identified two components: problem-solving and decision-making with an explained variance of 65.9%. For internal consistency, three different techniques were used and applied to the two components. All of the items have very good internal consistency (problem-solving Cronbach's alpha=0.931 and decision-making Cronbach's alpha=0.951).
The validation of the Portuguese scale agreed well with the existing literature. The scale can be divided into two components: the problem-solving component and the decision-making component. The translated scale demonstrated good internal consistency and can therefore be used in future studies.
将问题解决决策量表翻译成葡萄牙语并进行验证。
横断面研究。
问题解决决策量表从英语翻译成葡萄牙语，然后再回译，以获得最终版本。然后，从 2019 年 1 月到 3 月，在葡萄牙人口的代表性样本中进行了面对面的问卷调查，以验证该量表在葡萄牙人口中的适用性。
主成分分析和 Cronbach's alpha。
主成分分析用于评估量表内部结构的有效性。结果确定了两个分量：问题解决和决策，解释方差为 65.9%。对于内部一致性，使用了三种不同的技术，并应用于这两个分量。所有项目都具有非常好的内部一致性（问题解决 Cronbach's alpha=0.931，决策 Cronbach's alpha=0.951）。
葡萄牙语量表的验证结果与现有文献一致。该量表可分为两个分量：问题解决分量和决策分量。翻译后的量表具有良好的内部一致性，因此可以在未来的研究中使用。
