Percutaneous coronary intervention (PCI) is a nonsurgical procedure used in the treatment of coronary heart disease.
The purpose of this study was to validate a scale created in order to assess the importance and fulfillment of information needs in patients after PCI.
A 10-item scale was created by the researchers to explore the level of information needs and the level of fulfillment of these needs. The total scores have a possible range of 10 to 40 with higher scores indicating higher importance and fulfillment. The validation of the questionnaire included face and content validity, construct validity, internal consistency, repeatability, and discriminant validity.
Forty patients contributed to this validation. Mean and median scores for each question separately and also overall scores suggest that patients consider the need to be informed very important and that it was fulfilled to a very high degree (mean scores 39.5 and 39.3, respectively). All questions were found to be significantly correlated with the overall scores (rho > 0.3) meaning strong construct validity. Cronbach's α coefficients were high (>0.7) indicating great consistency. Both total scores had great repeatability, which suggests a high degree of reliability of the participants' responses (ICCs > 0.8). Regarding discriminant validity, a statistically significant association was observed only between marital status and the degree of fulfillment of the need to be informed (p = 0.036). More specifically, divorced or widowed patients had a lower degree of fulfillment than married patients (mean 38.6 vs. 39.6).
It is a reliable instrument that will help clinicians who are at close contact with patients after PCI to gain a better understanding of their needs.
经皮冠状动脉介入治疗（PCI）是一种用于治疗冠心病的非手术方法。
本研究的目的是验证一个为评估PCI术后患者信息需求的重要性和满足程度而创建的量表。
研究人员创建了一个包含10个条目的量表，以探究信息需求水平和这些需求的满足程度。总分范围为10至40分，分数越高表明重要性和满足程度越高。问卷的验证包括表面效度和内容效度、结构效度、内部一致性、可重复性和区分效度。
40名患者参与了此次验证。每个问题的平均分和中位数以及总分表明，患者认为需要了解信息非常重要，并且得到了很高程度的满足（平均分分别为39.5和39.3）。所有问题均与总分显著相关（rho>0.3），这意味着具有很强的结构效度。克朗巴哈α系数很高（>0.7），表明一致性很好。两个总分都具有很高的可重复性，这表明参与者的回答具有很高的可靠性（组内相关系数>0.8）。关于区分效度，仅在婚姻状况与信息需求满足程度之间观察到统计学上的显著关联（p=0.036）。更具体地说，离婚或丧偶患者的满足程度低于已婚患者（平均分38.6对39.6）。
这是一种可靠的工具，将有助于与PCI术后患者密切接触的临床医生更好地了解他们的需求。
