Background: As a primary phase of a Health Impact Assessment (HIA) on the Iranian Targeted Subsidy Plan (TSP), this study was conducted to assess the psychometric properties of a newly developed quantitative Health Policy Impact Assessment Tool (HEPIAT). Methods: In 2014, multistage cluster sampling was employed to recruit 509 key informants in Sanandaj, Iran, to participate in this cross-sectional study. A comprehensive literature review was conducted to develop the initial draft of HEPIAT. Content validity was determined by a consensus panel of experts, and construct validity and factor structure of the HEPIAT were assessed using Exploratory Factor Analysis (EFA). Reliability was assessed utilizing the Cronbach’ s alpha coefficient and the test– retest reliability coefficient. Results: Applying EFA, the optimal solution including 35 items and 6 factors was emerged, which accounted for 64. 94% of the total variance. The mean items’ relevancy, clarity, simplicity, and their total mean± SD score were 88. 3± 0. 2, 90. 1± 0. 5, 86. 1± 0. 7, and 89. 6± 0. 4, respectively. The scores of intra-class correlation coefficients (ICC) and internal consistency reliability for all the factors were ranged from 0. 67 to 0. 89. HEPIAT demonstrated an appropriate validity, reliability, functionality, and simplicity. Conclusion: Although further works in different settings are warranted, HEPIAT may be a practical and useful quantitative instrument in socioeconomic-related HIAs aimed to inform policymakers and stakeholders on the health impacts of their decisions and plans.
