Scale Measurement of Health Primary Service Utilization among the Migrant International Population

Area of Science:

• Public Health
• Health Services Research
• Migrant Health

Background:

• The World Health Organization (WHO) emphasizes the right to healthcare.
• International migrants face unique challenges in accessing healthcare.
• Assessing healthcare access requires validated measurement tools.

Purpose of the Study:

• To analyze the internal structure of the Experience in Exercising the Right to Health Care (EERHC) scale.
• To evaluate the psychometric properties of the EERHC scale for international migrants.
• To establish a reliable instrument for measuring primary health care utilization.

Main Methods:

• Instrumental study with 563 participants.
• Exploratory Structural Equation Modeling (ESEM) and Confirmatory Factor Analysis (CFA).
• Assessment of reliability (Cronbach's α, McDonald's ω) and internal consistency (item-dimension correlations).

Main Results:

• The EERHC scale demonstrated acceptable psychometric properties (Cronbach's α and McDonald's ω > 0.9).
• Item-dimension correlations were r ≥ 0.3.
• The final model showed good fit indices (RMSEA = 0.07, CFI = 0.97, TLI = 0.95, SRMR = 0.03).

Conclusions:

• The EERHC scale possesses a robust internal structure with 45 items across four dimensions.
• The validated scale is suitable for measuring primary health care service utilization among international migrants.
• Findings support the use of the EERHC scale within the WHO framework for the right to health care.
