Abstract
Objectives : To collect normative data and standardized scores for the MMPI-2-RF Thai version and compare Thai normative data with MMPI-2-RF English version
Materials and Methods : Normative data was collected by licensed clinical psychologists in each region. We collected data from 1,163 participants aged 18-80 years old. Data analysis was conducted by comparing the normative data of the Thai version and English version.
Results : Results showed that from 51 scales, there were no significant differences in K-r, BXD, RC9, JCP and IPP scales. However, comparing T-score and Uniform T-score showed that there were significant differences in F-r, Fp-r, RBS, THD, RC6 and PYSC-r. Other scales, on the other hand, were shown to be significantly similar to English version scores.
Discussion : In addition to the different scales recommended by experts at the University of Minnesota, cultural context plays a part in normalizing the standardization results. The fact that most of the values were close to the standard English version made it more confident to use the Thai version of the MMPI-2-RF as a basis for clinical diagnosis in the country.
Conclusion : Standard scores of the MMPI-2-RF Thai version are appropriate for clinical diagnosis in the Thai population.
