Abstract

Introduction: Ischemic Heart Disease (IHD), a major cardiovascular disease globally, has become the primary cause of death in Sri Lanka. Negative affectivity (NA) and social inhibition (SI) are two personality traits which increase the risk of IHD. The Type D Scale (DS-14) evaluates a person's general level of distress on NA and SI. However, DS-14 has not been translated and validated into Sinhala in Sri Lanka.

Objectives: The study aimed to cross-culturally adapt and validate the DS-14 for use with Sinhala speaking patients diagnosed with IHD.

Methods: Translation, back translation and pre-test were conducted before a two-rounds of a Delphi process which assessed content and consensual validity of the instrument. The validated questionnaires were administered to 140 patients diagnosed with IHD at a Base Hospital. Factor structure was confirmed through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) and reliability, by internal consistency with Cronbach's alpha.

Results: The questionnaire was administered among 140 participants (85 females), aged 18-60 years. The DS-14 Sinhala version showed good content and consensual validity. Factor analysis proved two factors compatible with the original instrument, which explained the variance of 62.9%. CFA confirmed the two-factor model. The reliability analysis indicated Cronbach's alpha for NA and SI as 0.93 and 0.88, respectively.

Conclusion: The cross-culturally adapted DS-14 Sinhala version indicated the same psychometric properties as the original instrument, in the local context with IHD patients. It can be confidently applied in the investigation of Type D personality in IHD prevention and treatment, as well as in research.

斯里兰卡诊断为缺血性心脏病患者的D型人格量表的跨文化适应
简介:缺血性心脏病(IHD)是全球主要的心血管疾病,已成为斯里兰卡的主要死亡原因。负性情感(NA)和社会抑制(SI)是增加IHD发病风险的两种人格特征。D型量表(DS-14)评估一个人在NA和SI上的总体痛苦水平。然而,DS-14尚未在斯里兰卡翻译和验证为僧伽罗语。目的:该研究旨在跨文化适应和验证DS-14用于诊断为IHD的僧伽罗语患者。方法:进行翻译、反译和预测试,然后进行两轮德尔菲程序,评估工具的内容和共识效度。对某基地医院140名诊断为IHD的患者进行了有效的问卷调查。通过探索性因子分析(EFA)和验证性因子分析(CFA)来确定因子结构,并通过与Cronbach's alpha的内部一致性来确定信度。结果:共收集问卷140份,其中女性85份,年龄18 ~ 60岁。DS-14僧伽罗语版本显示了良好的内容和共识有效性。因子分析证实两个因子与原仪器相容,解释方差为62.9%。CFA验证了双因素模型。信度分析显示,NA和SI的Cronbach's alpha分别为0.93和0.88。结论:跨文化改编的DS-14僧伽罗语版本在当地IHD患者中显示出与原始仪器相同的心理测量特性。它可以自信地应用于D型人格的调查和IHD的防治,以及研究中。

期刊介绍: The Ceylon Medical Journal, is the oldest surviving medical journal in Australasia. It is the only medical journal in Sri Lanka that is listed in the Index Medicus. The CMJ started life way back in 1887 as the organ of the Ceylon Branch of the British Medical Association. Except for a brief period between 1893 and 1904 when it ceased publication, the CMJ or its forbear, the Journal of the Ceylon Branch of the British Medical Association, has been published without interruption up to now. The journal"s name changed to the CMJ in 1954.
