BACKGROUND: Cardiovascular diseases are among progressive diseases that begin in childhoodand are manifested mainly in adulthood. This study was assessed the validity and reliability testingof the Persian version of the Perceived Health Competence Scale (PHCS) among patients withcardiovascular diseases referred to Shahid Rajaie Heart center in Tehran, Iran.METHODS: In this cross‑sectional study, a convenience sample of 700 patients with cardiovasculardiseases referring to Shahid Rajaie Heart center in Tehran were recruited (response rate = 100%;n = 700). Content validity was established using translation and back‑translation procedure and gettingviews of the expert panel. The content validity of the questionnaire was measured using contentvalidity ratio (CVR) and content validity index (CVI). Reliability was ascertained using Cronbach’salpha. The stability was confirmed using intra‑class correlation coefficients.RESULTS: 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 was0.75.CONCLUSIONS: The PHCS‑Persian confirmed as a valid and reliable instrument to measureperceived health competence. The PHCS‑Persian scale could be a useful, comprehensive, andculturally sensitive scale for assessing perceived health competence.
