Cardiovascular diseases are among progressive diseases that begin in childhood and are manifested mainly in adulthood. This study was assessed the validity and reliability testing of the Persian version of the Perceived Health Competence Scale (PHCS) among patients with cardiovascular diseases referred to Shahid Rajaie Heart center in Tehran, Iran.
In this cross-sectional study, a convenience sample of 700 patients with cardiovascular diseases referring to Shahid Rajaie Heart center in Tehran were recruited (response rate = 100%; = 700). Content validity was established using translation and back-translation procedure and getting views of the expert panel. The content validity of the questionnaire was measured using content validity ratio (CVR) and content validity index (CVI). Reliability was ascertained using Cronbach's alpha. The stability was confirmed using intra-class correlation coefficients.
In this study, CVI = 0.81 and CVR = 0.72 were calculated. Scale reliability was sufficient (α = 0.78; range = 0.73-0.77). Furthermore, reliability based on the stability of the whole scale was 0.75.
The PHCS-Persian confirmed as a valid and reliable instrument to measure perceived health competence. The PHCS-Persian scale could be a useful, comprehensive, and culturally sensitive scale for assessing perceived health competence.
心血管疾病属于始于儿童期并主要在成年期表现出来的渐进性疾病。本研究评估了在伊朗德黑兰被转诊至沙希德拉贾伊心脏中心的心血管疾病患者中，波斯语版健康感知能力量表（PHCS）的有效性和可靠性测试。
在这项横断面研究中，招募了700名方便样本的心血管疾病患者，他们被转诊至德黑兰的沙希德拉贾伊心脏中心（回复率 = 100%；n = 700）。通过翻译和回译程序并征求专家小组的意见来确定内容效度。使用内容效度比（CVR）和内容效度指数（CVI）来测量问卷的内容效度。使用克朗巴赫α系数确定信度。使用组内相关系数确认稳定性。
在本研究中，计算得出CVI = 0.81，CVR = 0.72。量表信度足够（α = 0.78；范围 = 0.73 - 0.77）。此外，基于整个量表稳定性的信度为0.75。
波斯语版PHCS被确认为测量健康感知能力的有效且可靠的工具。波斯语版PHCS量表可能是评估健康感知能力的一个有用、全面且具有文化敏感性的量表。
