Psychometric properties of the Thai Qualifications Framework for Higher Education instrument among Royal Thai Air Force nurse stakeholders

Background: The Thai Qualifications Framework for Higher Education (TQF: HEd) serves as
a framework to enhance the quality of higher education in Thailand. However, no valid and
reliable TQF: HEd instrument is available to measure the quality of graduates among Royal
Thai Air Force Nurses.
Objective: This study aimed to assess the psychometric properties of the TQF: HEd
instrument among graduate nurses of the Royal Thai Air Force.
Methods: Psychometric testing of the instrument was conducted. The instrument’s validity
was evaluated through a review by a panel of five experts, providing a content validity index
(CVI). Construct validity was assessed using Confirmatory Factor Analysis (CFA) with a
sample size of 308, and Cronbach’s α coefficient was utilized to measure the scale’s internal
consistency.
Results: The Scale-Content Validity Index (S-CVI) was 0.88. CFA yielded the following fit
indices: 2 = 265.861, p = 0.068, df = 233, 2/df ratio = 1.141, Comparative fit index (CFI) =
0.996, Tucker Lewis Index (TLI) = 0.993, Root Mean Square Error of Approximation (RMSEA)
= 0.021, and Standardized Root Mean Square Residual (SRMR) = 0.033. The scale reliability
was acceptable, with a Cronbach’s alpha coefficient of 0.93 and 0.85-0.92 for the six factors.
Conclusion: The TQF: HEd instrument demonstrates satisfactory psychometric properties,
which will be valuable for those in charge of the curriculum in utilizing the instrument to
measure graduate competency and guide curriculum development.
