This article aims to review the linguistic adaptation and psychometric validation of psychological assessment instruments through a narrative review. Linguistic adaptation involves translating and culturally adjusting instruments to fit the target population, while psychometric validation assesses reliability using indicators such as Cronbach's Alpha (α≥0.70) and McDonald's Omega (ω≥0.70). Additional reliability measures include Guttman's Lambda (λ≥ 0.70) and Composite Reliability (CR≥ 0.70). Validity is evaluated through the Average Variance Extracted (AVE≥ 0.50) and the Heterotrait-Monotrait Ratio (HTMT≤ 0.85). Model fit is assessed using indices such as CFI (≥ 0.90), TLI (≥ 0.90), NFI (≥ 0.90), NNFI (≥ 0.90), RFI (≥ 0.90), IFI (≥ 0.90), GFI (≥ 0.90), AGFI (≥ 0.90), PGFI (≥ 0.50), PNFI (≥ 0.50), PCFI (≥ 0.50), RMSEA (≤ 0.08 acceptable, ≤ 0.05), and SRMR (≤ 0.08). Confirmatory Factor Analysis (CFA) is also employed to investigate measurement invariance, ensuring the stability of the instrument across different groups.
